Just adding this to a Rails 3.2.13 app. I created the Dropbox app just for this use but when I run the rake task I get an error:

Error getting request token. Is your app key and secret correctly set? Server returned 403: Forbidden.

As the screencap shows, I have set to app_folder.

If I change the file name on dropbox (outside of the gem), then try to display the URL link with something like

<% if direct_purchase.receipt_file_size != nil %>
        <td><%= link_to direct_purchase.purchase_date, direct_purchase.receipt.url %></td>
    <% else %>
        <td><%= direct_purchase.purchase_date %></td>
    <% end %>

I get a DropboxError saying the path is not found.

Is there a way to check if the path is valid?

I just installed this gem and followed the readme me to configure paperclip for dropbox. I used a yaml file to set my credentials.

I was able to upload to dropbox just fine, but when I tried to display my image with .url, I got the following exception:

undefined method `[]' for #Pathname:0x007fce810b02a0

After reconfirming that I had set everything up correctly, I traced the code and discovered that error was occurring in UrlGenerator#user_id.

def user_id
    @attachment_options[:dropbox_credentials][:user_id]
end

For some reason @attachment_options[:dropbox_credentials] is not a hash, but a Pathname. Since it's a Pathname [:user_id] causes an exception. If i change :dropbox_credentials to a hash in my model, @attachment_options[:dropbox_credentials] is a hash and everything works as expected.

My system configuration is:

ruby 2.1.3p242 (2014-09-19 revision 47630) [x86_64-darwin14.0]
Rails 4.1.1
paperclip (4.2.1)
paperclip-dropbox (1.3.0)

So, I have a model which has two icons:

class Category < ActiveRecord::Base
  has_many :events

  has_attached_file :black_icon, styles: { small: '30x30' },
    storage: :dropbox,
    dropbox_credentials: Rails.root.join('config/dropbox.yml')

  has_attached_file :white_icon, styles: { small: '30x30' },
    storage: :dropbox,
    dropbox_credentials: Rails.root.join('config/dropbox.yml')
end

If I use ActiveAdmin to upload two files named computing.png, both files do show up in my Dropbox folder (along with their :small variations). However, on trying to display the images, both are the same, either both black or both white.

Sorry for the lack of specificity, I'm just getting started with Rails. However, this was not an issue when not using paperclip-dropbox.

I have integrated paperclip-dropbox in my application and follwed all steps as described. Its working fine if I am storing an image. The image is properly being saved in my dropbox account. But when i try to access the image using the url generated by paperclip, the image is not found.

Even if i try the url in a seperate tab, it says:

Error (404)
We can't find the page you're looking for. Check out our Help Center and forums for help, or head back to home.

Does anyone have any idea, how to access the image from dropbox using this paperclip-dropbox gem or i am missing something.

Hello,

I am having a difficult time figuring out how to download a file via the browser after it has been uploaded using paperclip-dropbox. My original plan was to download the file using httparty then use send_file to present the file. This has not been working for me. Even if it has, because my app is hosted on herokuapps.com I doubt that I would be able to use this same tactic.

Is there a particular way that I need to go about doing this?

Hi Janko,

Thank you for creating this excellent gem! I'm a Rails instructor for BaseRails (www.baserails.com) and for the past couple months, I've been teaching my students to use your gem for image hosting due to its ease of use over other alternatives.

A few days ago, one of my students notified me about the recent update to the paperclip gem (http://www.theregister.co.uk/2014/02/09/content_type_spoofing_bug_in_ror_paperclip/). I've been telling them to hold off on upgrading to paperclip 4 because paperclip-dropbox still relies on paperclip 3. Are you planning to update your gem to the latest version of paperclip? Please let me know - thanks!

Best,
Alex

Is it possible to do something like this:

dropbox_credentials: Proc.new do |a|
    {
        app_key: "xxxxxxxxxxxxxxx", 
        app_secret: "xxxxxxxxxxxxxxx", 
        user_id: "xxxxxxxx",
        access_type: "app_folder",
        access_token: a.instance.user.token, 
        access_token_secret: a.instance.user.secret
    }
end

What I am trying to do is get the user's token and secret that belongs to this model (asset). Something kind of similar but for S3: http://rubydoc.info/gems/paperclip/Paperclip/Storage/S3.

Any help will be much appreciated, thanks!

When i delete instance of model in my application by using destroy method - image - in dropbox still remain. Should it be deleted or not?

Just trying out paperclip-dropbox but without much success. Here what I have done.

In my Gemfile:

gem 'paperclip'
gem "paperclip-dropbox"

Created an App on dropbox and followed these instructions: https://github.com/janko-m/paperclip-dropbox

In my dropbox.yml

development:
  app_key: APP_KEY
  app_secret: APP_SECRET
  access_token: ACCESS_TOKEN
  access_token_secret: ACCESS_TOKEN_SECRET
  user_id: USER_ID

production:
  app_key: APP_KEY
  app_secret: APP_SECRET
  access_token: ACCESS_TOKEN
  access_token_secret: ACCESS_TOKEN_SECRET
  user_id: USER_ID

In my User model:

has_attached_file :avatar, 
  :styles => {
    thumb: '100x100>',
    square: '200x200#',
    medium: '300x300>' }

In my view:

<%= image_tag @user_profile.avatar.url(:square), :size => '100x100' %>

Error message:

You have a nil object when you didn't expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.[]  
Pointing at my image_tag line of code.

Note that paperclip worked real well using the local filesystem.

Any ideas?

Hi

I have a problem with load file (in this case is image) from dropbox. I want to create a user that have an avatar like a demo in here, with a little modification. I tried to upload an image and the image is uploaded successfully in dropbox, and my table (in this case users table) was updated, but it can't be loaded. I have seen this issue, but it didn't work. Here is my code:

Gemfile

  def update_account
    @user = User.find(current_user.id)
    if @user.update(account_params)
      redirect_to(profile_path(@user.id))
    else
      render 'edit_account'
    end
  end

  def self.up
    add_attachment :users, :avatar
  end

  def self.down
    remove_attachment :users, :avatar
  end
end

it created 4 new columns: avatar_file_name, avatar_content_type, avatar_file_size, and avatar_updated_at

and dropbox.yml

access_token: "qd7csbjebxxxxxxx"
access_token_secret: "pni29r74xxxxxxx"
user_id: "293122165"
access_type: "dropbox"

First, I try to upload an image (it use edit_account.html.erb). After upload the image, open route /profile/:id, that render show.html.erb, the tag <%= image_tag @user.avatar.url %> give me a result <img alt="2426742 41674 108550" src="https://dl.dropboxusercontent.com/u/293122165/2426742-41674-108550.jpg" />. I try to go to that link with my browser, it says "Not Found The resource could not be found." What's wrong with my code? Or, my dropbox app is the problem? I don't know how to create dropbox app because I didn't found any tutorial how to create it.... So, I try to create Dropbox app with some guessing:

1. Go to this link
2. Click Dropbox API app
3. It asks What type of data does your app need to store on Dropbox? so I choose Files and datastores
4. It asks Can your app be limited to its own folder? so I choose No My app needs access to files already on Dropbox.
5. What type of files does your app need access to? and then I choose All file types My app needs access to a user's full Dropbox. Only supported via the Core API.
6. And it asks Provide an app name, and you're on your way. and I typed my app name there.

The result is my dropbox app settings:
Status: Development
Development users: Only you
Permission type: Full Dropbox
App key: q45pb9tzxxxxxxx
App secret: gbt9nw02xxxxxxx
OAuth2: Redirect URIs <-- I leave it blank because I don't understand what is it used for.
Allow implicit grant: Allow
Drop-ins domains: <-- I leave it blank because I don't understand what is it used for.
Webhooks: Webhook URIs <-- I leave it blank because I don't understand what is it used for.

Did I miss something? Or, did I happen something wrong? I try this in development mode.

Thanks

I just switched from the app folder option to the public directory because of the latency from dropbox.

The only thing is that now file uploads don't work anymore, i get a 'DropboxError (Forbiden)'. I triple checked my newly generated credentials in my credentials file and setted access_type to dropbox.

Here is what i did :
rake dropbox:authorize APP_KEY= APP_SECRET= ACCESS_TYPE=dropbox
Then authorized and successfuly got my credentials
Added everything to a config/dropbox.yml following the structure in the example but without the environnement variables.
Then left everything else the same way

I made a custom path for my images. Can it be the source of the problem maybe ?

If it can help i'm using the latest commited version from your repo (because i need default url interpolation).

Thank you for your help

Hi,

I noticed that calling model_obj.attachment_name.exists? when the model does not have an attachment (in my application it is optional) raises a TypeError:

[1] pry(main)> e = Entry.find_by_title "foobar"
[2] pry(main)> e.photo.exists?
TypeError: no implicit conversion of nil into String
from /Users/Tom/.rvm/gems/ruby-2.0.0-p195/gems/paperclip-dropbox-1.1.5/lib/paperclip/storage/dropbox/path_generator.rb:37:in `extname'

I could fix this by implementing a custom query method:

  def photo_exists?
    return self.photo.exists?
  rescue TypeError => er
    return false
  end

so that:

[5] pry(main)> e.photo_exists?
=> false

Credentials are ok, because if I visit the URL in my browser I can authorize my app but from the command line I get a 401.

DropboxAuthError: Couldn't get access token.  Server returned 401: Unauthorized.

When doing the rake dropbox:authorize APP_KEY=your_app_key APP_SECRET=your_app_secret rake task, it provides an authorization URL and then gives the access token/secret with user id. But then it does that all again for some reason.

When i upload file(pdf) via my app, I see that the default expiration date for all files is 0 day,
is there any way to upload file without existing of expiration date ? thanks

I'm looking through the source code and it appears that the user_id is only needed for app folder, so should this be optional? Also I have no idea where to get my user_id dropbox from, some instructions would help.

default_url option which is set in config.paperclip_defaults is not showing up. So I'm not able to see default image even though I set this option.

Hello, i have used the :default_url option in my user model and created the correct files in my asset pipeline. the user model looks like this:
has_attached_file :avatar, :styles => { :medium => "300x300>", :thumb => "100x100>", :small=>"80x80>" }, :default_url => ActionController::Base.helpers.asset_path("Bob_:style.jpg")

and i have a imges/Bob_small.jpg etc..

can someone tell me please why is this not working?

I am using gem "figaro" to host my variables and the form is a a nesteed form using the gem "nested_form". I was also able to get the user information information without a problem previously.

class LineImage < ActiveRecord::Base
  belongs_to :line_item
  attr_accessible :image, :location
  has_attached_file :image,
    storage: :dropbox,
    dropbox_credentials: {
        app_key: ENV['DROPBOX_APP_KEY'], 
        app_secret: ENV['DROPBOX_APP_SECRET'], 
        access_token: ENV['DROPBOX_ACCESS_TOKEN'],
        access_token_secret: ENV['DROPBOX_ACCESS_TOKEN_SECRET'],
        user_id: ENV['DROPBOX_USER_ID']
    }
  validates_presence_of :location
end

And my full-trace from the error:
https://gist.github.com/blklane/7753096

If a user doesn't specify app key and app secret in the Rake task, try to read them from config/dropbox.yml.

Hi.. I know this it a old issue (issues number 13). I'm using this gem with active-admin gem.

this is the model

class Category < ActiveRecord::Base
  has_many :photo

  attr_accessible :name, :desc

  attr_accessible :image

  has_attached_file :image,
    :storage => :dropbox,
    :dropbox_credentials => "#{Rails.root}/config/dropbox.yml",
    :dropbox_options => {
      :path => proc { |style| "#{style}/#{id}_#{image.original_filename}" }
    }

  validates :name, :uniqueness => true
  validates_attachment_presence :image
  validates_attachment_size :image, :less_than => 1.megabytes
  validates_attachment_content_type :image, :content_type => ['image/jpeg', 'image/png']

end

active_admin DSL file

ActiveAdmin.register Category do

  index do
    selectable_column
    column :name
    column :image_file_name do |photo|
      image_tag photo.image.url(:thumb)
    end
    default_actions
  end

  form do |f|
    f.inputs "Category Details" do
      f.input :name
      f.input :desc, :lable => "Description", :input_html => { :class => "tinymce" }
      f.input :image, :as => :file
    end
    f.buttons
  end

end

I was attempting to install your gem and ran into an issue. I wasn't sure if I should put this issue on github or if it was just something I am not doing correctly.

Here is what I did step by step, maybe you can see where I am doing something wrong.

• Installed paperclip
• Installed paperclip-dropbox
• generated paperclip fields for db
• rails g paperclip blog document
• added the following:

has_attached_file :document,
  storage: :dropbox,
  dropbox_credentials: {
    app_key: List.where(name: 'blog_dropbox_key').first.list,
    app_secret: List.where(name: 'blog_dropbox_secret').first.list,
    access_token: "..."
    access_token_secret: "..."
    user_id: "[email protected]"
    access_type: "dropbox"},
  dropbox_options: {environment: Rails.env}

• Tried to authorize my application for use with dropbox:

rake dropbox:authorize [email protected] APP_SECRET=mypassword ACCESS_TYPE=dropbox

I get the following error when I run that last comment:

rake aborted!

Hi,

I've noticed that it takes a couple of seconds for the Dropbox API to generate a URL.
Would it be safe to cache them in a DB column? I can't find any information on Dropbox URL expiration (for applications).

Thanks!

I keep getting:

undefined method `image' for #<LineImage:0x007fef5daa2220>

I had the original paperclip gem when I created the model/attribute then then changed it out for this gem and it no longer works, any Ideas? I am using the LineImage in a nested_form thanks to the gem "nested_form"

class LineImage < ActiveRecord::Base
  belongs_to :line_item
  attr_accessible :image, :location
  has_attached_file :image,
    storage: :dropbox,
    dropbox_credentials: {
        app_key: ENV['DROPBOX_APP_KEY'], 
        app_secret: ENV['DROPBOX_APP_SECRET'], 
        access_token: ENV['DROPBOX_ACCESS_TOKEN'],
        access_token_secret: ENV['DROPBOX_ACCESS_TOKEN_SECRET'],
        user_id: ENV['DROPBOX_USER_ID'],
        access_type: dropbox
    },
    dropbox_options: {path: proc { "#{id}_#{image.original_filename}"}},
    unique_filename: true
  # validate :validates_presence_of_image
  validates_presence_of :location, :image

  # def validates_presence_of_image
  #     return (image.exists? ? true : false)
  # end
end

Hi Janko,

First off, thanks for a great gem! I wanted to see when pull request #31 will be incorporated to the gem (or if it already is I could be doing something wrong). I'm trying to save a file a specific folder w/in dropbox and after looking at the updated source code I thought it should work by setting the :dropbox_visibility => 'private' and also by specifying the desired path. After a few tries I notice the code dropbox.rb code in my app didn't match what I was seeing on github, Screenshot http://d.pr/i/gatW.

Please let me know if this makes sense...or if I'm totally off...and thanks again for your help!

    :dropbox_credentials => {app_key: "123445", app_secret: "1234456", access_token: "123456", access_token_secret: "123456", user_id: "191409863"}

  validates_attachment_content_type :avatar, :content_type => ["image/jpg", "image/jpeg", "image/png", "image/gif"]

It is uploading the file to my dropbox successfully. So when I try User.first.avatar.url, its generates url like this https://dl.dropboxusercontent.com/u/191409863/mclarenp1_QY5vmfTw.jpg when I access this, the page shows dropbox error page instead on image.

It's very difficult at the moment to change the Model.attachment.url's(dropbox url's).

Example:

class Item < ActiveRecord::Base
    has_attached_file :picture_1, { dropbox_options: { path: proc { "#{self.id}_1" }  }, default_url: "default.png" }
    has_attached_file :picture_2, { dropbox_options: { path: proc { "#{self.id}_2" }  }}
    has_attached_file :picture_3, { dropbox_options: { path: proc { "#{self.id}_3" }  }}

    validates_attachment_content_type :picture_1, content_type: /\Aimage\/.*\Z/
    validates_attachment_content_type :picture_2, content_type: /\Aimage\/.*\Z/
    validates_attachment_content_type :picture_3, content_type: /\Aimage\/.*\Z/

end

Also I have to manually add a callback when the models referred to self.id changes.(eg. if we change the id of an item that has an attachment, dropbox url wont change automatically so samemodel.picture_1.url would cause an error).

I think we need a better API + handling for dropbox uploads.

The readme says that the :path parameter works similar to paperclip's path parameter. However, when I tried to utilize the a path schema like paperclip's default which places it in a folder by class using ":class", I found it was simply stored under a folder called ":class" instead of the class name.

I looked through all the documentation I could find in both your gem and paperclip's as well as google for a few days now, but could not find a way to get the class name inside of the dropbox path.

class ClassSession < ActiveRecord::Base
  attr_accesible :icon
  has_attached_file :icon,
    styles: { icon: "65x65^"},
    :storage => :dropbox,
    :dropbox_credentials => "#{Rails.root}/config/dropbox.yml",
    :dropbox_options {
      path: proc { |style| "MyApp/:class/#{style}/#{id}" },
    }
end

Expected result: file saved at Public/MyApp/ClassSession/icon/1_icon.png
Actual result: file saved at Public/MyApp/:class/icon/1_icon.png

How would I be able to achieve this?

And as a side question, why doesn't the gem use paperclip's path parameter instead of its own?

I have users table and I call the user's image_url on a view like this:

current_user.image.url

but sometimes it very slow because It's requesting the url from Dropbox every time you load the view.

I'm thinking of a callback and add the dropbox url to an attribute:
I have avatar_url on users table.

I tried to use

before_save :set_avatar_url

private

def set_avatar_url
   self.avatar_url = logo.url
end

but I'm getting

Path '/14556_937298776286928_704613103_n.png' not found

Seems like I'm able to upload an image to dropbox, it appears in my Public folder as:
tumblr_mbc58jDnZz1rshp39o5_250.png (there are 2 more files with thumb and medium appended)
Should they be in directories within the Public directory?

When I want to display an image:
<%= image_tag @post.photo.url(:medium) %>
The image is broken, the URL which is output in HTML is:
http://dl.dropbox.com/u/112885775/tumblr_mbc58jDnZz1rshp39o5_250_medium.png

If I go to that image, I get a 404 error.

What do I do?

I followed all the instructions, having previously successfully implemented paperclip-dropbox. But I'm getting this error whenever I upload a file:

Image /var/folders/7x/y47hx14s11vf895wwgk9rkqw0000gn/T/Henry 00420121019-852-12mfi2c.jpg is not recognized by the 'identify' command.

I have an older dropbox account with an existing Public folder, but I enabled it anyway.

Hello!

I have created a small application, using the instructions from the readme file.

Here is the model code:

class User < ActiveRecord::Base
  attr_accessible :avatar
  has_attached_file :avatar, 
    :styles => { :medium => "300x300>", :thumb => "100x100>" },
    :storage => :dropbox,
    :dropbox_credentials => "#{Rails.root}/config/dropbox.yml",
    :dropbox_options => {
      :path => proc { |style| "#{style}/#{id}_#{avatar.original_filename}" }
    }
end

Here is the controller code:

class UsersController < ApplicationController

  def new
    @user = User.new
  end

  def create
    @user = User.new( params[:user] )
    if @user.save
      redirect_to @user
    else
      render :action => "new"
    end
  end

  def show
    @user = User.find(params[:id])
  end

end

So when I try to create a new user, server throws an error:

[paperclip] Saving attachments.
   (0.8ms)  rollback transaction
Completed 500 Internal Server Error in 2072ms

NoMethodError (undefined method `gsub' for nil:NilClass):
  app/controllers/users_controller.rb:9:in `create'

Local storage works just fine. Could you please look at this?

my rails app is configured to use the app_folder access but when I try to upload a file in development, Rails throws me this error:

Host: rpc.dropbox.com:443, FE: None, X-Dropbox-RequestId: None, X-Dropbox-App-Error: None, Full Dropbox access attempt failed because this app is not configured to have full Dropbox access.  Should your access type be app folder ('sandbox') instead?

At first I thought maybe I entered the value wrong. My variable looks like this:

DROPBOX_ACCESS_TYPE: app_folder

Any ideas?

This isn't really and issue, but It obviously takes a little while for a picture to be uploaded to dropbox.
For user experience's sake I would like to display an progress bar. Is it possible to do so?

This gem core purpose renders obsolete as there's no posibility for a normal account to have a public folder. All links created by model.url get a 403 reposnse.

This gem was awsome but please update its readme so no more people lose their time as I did.

Thank you.

Hello. I followed the post of you and took a searched on google and found nothing relating to this error. will be someone who could help me? thank you

Hi,

I have following the setup installation of the paperclip-dropbox for rails.

I have this in my listing.rb file

class Listing < ActiveRecord::Base
has_attached_file :image, :styles => { :medium => "200x>", :thumb => "100x100>" }, :default_url => "default.jpg"
validates_attachment_content_type :image, :content_type => %w(image/jpeg image/jpg image/png), 
        :storage => :dropbox,
    :dropbox_credentials => Rails.root.join("config/dropbox.yml"),
    :path => ":style/:id_:filename"
end

When i upload an image, it storages in my localhost folder and not in the dropbox.

I'm naming my files based on some record entries (date for example). If one of these data fields is changed by the user, I would like to rename the file to match. Is it possible to do this?

Hi @janko-m I'm using paperclip-dropbox >= 1.1.7
then here are my attributes:

• avatar
• avatar_file_name
• avatar_content_type
• avatar_file_size:
• avatar_updated_at:

and in my form:

= f.file_field :avatar

and in my model

  has_attached_file :avatar,
        :storage => :dropbox,
        :dropbox_credentials => Rails.root.join("config/dropbox.yml"),
        :dropbox_visibility => 'public'

then when I add an image I can upload the image to dropbox and
these attributes has a values avatar_content_type, avatar_file_size, avatar_updated_at
but it cannot store the uploaded image url. Please help thanks!

PS. I'm using a non-premium dropbox account and the images we're uploaded in Apps/my_images folder in Dropbox.

Hello !

I have a problem when I try to show a picture.

I follow the readme and I have no problem to upload. But, when I try to show I picture, I have this error :

Cannot load storage module 'Dropbox'

Any ideas ?

Thanks !

I have been attempting to upload a file via the rails console and have not had any luck. Unfortunately the only error I get is DropboxError: Forbidden. The log file doesn't show any additional errors so I'm at a loss on how to debug this. What I have in my model is:

has_attached_file :document,
                     storage: :dropbox,
                     dropbox_credentials: {
                       app_key: "...",
                       app_secret: "...",
                       access_token: "...",
                       access_token_secret: "...",
                       user_id: "123456789"
                     },
                     dropbox_options: {environment: Rails.env},
                     access_type: 'app_folder
 validates_attachment_content_type :document, :content_type => /\Aimage\/.*\Z/

I am looking for any ideas on how I can figure out is not right and how I can fix it so I can upload a file to my dropbox account. Any help is appreciated.

After I run the rake task, I get this:

And after you approved the authorization confirm it here (y/n): y
rake aborted!
ArgumentError: root must be :dropbox, :app_folder, or :auto
/home/vagrant/.rvm/gems/ruby-2.1.2@vaipradisney/gems/dropbox-sdk-1.6.4/lib/dropbox_sdk.rb:738:in `initialize'

I've had this gem running for over a year with no issues. Suddenly after my last Gemfile update, I am getting this error for every view reference to an uploaded file:

View:
<%= image_tag current_user.avatar.url(:thumb) %>

Error:
ActionView::Template::Error (no implicit conversion of Symbol into Integer):

Confirmed that current_user.avatar.url and current_user.avatar.url(:thumb) both throw this error in the console as well.

For now I changed the view to this:
<%= image_tag current_user.avatar.dropbox_client.media(current_user.avatar.path)["url"] %>

Which works, but I don't understand why the former doesn't work.

Running Railss 4.2, Paperclip 4.2, and Paperclip-Dropbox 1.2.1 ... though I tried a whole bunch of different combinations and could never resolve the error. Was unable to find a solution on StackOverflow or other forums; hoping you may have an idea. Thanks!

Hello!

I have created a small application, it works perfect locally, but when I run it in heroku it doesn't found the url and break down.
This is the code,

# app/models/image.rb
class Image < ActiveRecord::Base 
    belongs_to :store
    has_attached_file :avatar, 
        :storage =>:dropbox, 
        :dropbox_credentials => Rails.root.join("config/dropbox_config.yml"),
            :path => "app/:class/:attachment/:id/:basename.:extension"
    validates_attachment_content_type :avatar, :content_type => /^image\/(png|gif|jpeg)/
end

When I upload an image it save it correctly (the image appear in my dropbox), but it fall when i put this code to show it:

When I run the heroku rails console "image.first.avatar.url" it tell me:
NoMethodError: undefined method `generate' for nil:NilClass

If i put "Image.first.avatar" it shows:
"=> #<Paperclip::Attachment:........."

Do you know what is wrong?
