Hi. Thanks for your gem! I have one problem with reupload image.
I select image with aspect 16:9 from my pc, cropbox works correct. After i would exchange this image(16:9) with image 4:5 and this look so stretched. Can you help me solve my problem?

PS Sorry for my bad English :(

When I upload an image (960 x 539) like this, everything is OK.

but when I upload an image with very different dimensions (550 x 800), this happens:

I'm not using the default width and height attributes because I want full width images.
So, How can I fix this?

Hi, nice fork from the orginal one.
I have this issue

POST /users.json

def create
@user = User.new(user_params)

respond_to do |format|

My private controller for user looks like this
private
# Use callbacks to share common setup or constraints between actions.
def set_user
@user = User.find(params[:id])
end

# Never trust parameters from the scary internet, only allow the white list through.
def user_params
  params.require(:user).permit(:avatar, {avatars: []}, :avatar_cache, :favatar_crop_x, :avatar_crop_y, :avatar_crop_w, :avatar_crop_h)
end

end

Hi, I have issue when try to update(edit) scaffold crop image it will not update the image.
I have used the crop-on-fly here http://46.101.120.93/
Do I need profiles_controller.rb define the crop? https://github.com/vjandrei/rails4_snappaajat/blob/DeployTestCapistrano/app/controllers/profiles_controller.rb

Hi,

Thanks for amazing gem ;)

I installed in my app and i have an issue!

When the user already exist and have an avatar that was uploaded before, all the fields work fine.

<%= form_for @Profile do |f| %>
<%= f.cropbox :avatar, width: 250, height: 250 %>
<%= f.file_field :avatar %>
<%= f.previewbox :avatar %>
<%= f.submit 'Crop and Save' %>

But when there is no avatar yet "first time that avatar will be uploaded"

I get the message:

nil is not a valid asset source

And the two field that dont work are:

<%= f.cropbox :avatar, width: 250, height: 250 %>
<%= f.previewbox :avatar %>

How to deal with first time upload image?

Thanks a lot!
