CarrierWare how get image dimension (wigth, height)? about cloudinary_gem HOT 9 CLOSED

Pinging this one. Would it be possible to add an easy way to get the width / height from the uploaded JSON for those of us that store that in the model?

from cloudinary_gem.

All the metadata returned from Cloudinary can be accessed right after the upload using the metadata method on the uploader. You can add the following to your model to retrieve the width and height (picture is the name of mounted upload) -

after_save :update_dimensions

def update_dimensions
  if self.picture.present? && self.picture.metadata.present?
    width = self.picture.metadata["width"]
    height = self.picture.metadata["height"]
    # TODO: Update model entity
  end
end

from cloudinary_gem.

metadata is nil for me... I have an extremely basic uploader:

class ImageUploader < CarrierWave::Uploader::Base
  include Cloudinary::CarrierWave
  def public_id
    "#{model.class.to_s}-#{model.slug}"
  end
end

And mounted:

class Photo < ActiveRecord::Base
  mount_uploader :image, ImageUploader
end

I've tried both before_save and after_save. On both of them image.metadata is nil...

from cloudinary_gem.

Please make sure after_save is placed after the mount_uploader definition (otherwise the callbacks are called in the wrong order).

from cloudinary_gem.

It is. The mount_uploader is at the very top of my model definition and I tried callback at bottom. It seems to be getting cleared out.

Can you please try to add the following to the end of the Photo class:

after_save :testmd
def testmd
  puts "HERE #{self.image.metadata.inspect}"
end

And upload using the rails console:

Photo.create(:remote_image_url=>"http://cloudinary.com/images/logo.png")

from cloudinary_gem.

Weird. I must have something conflicting with it:

/Users/ehochber/.rvm/gems/ruby-2.0.0-p0@thg/gems/activerecord-3.2.13/lib/active_record/persistence.rb:85
rescue ActiveRecord::RecordInvalid

from cloudinary_gem.

Maybe you have :null=>false fields in the photos table?
If remote_image_url is the issue, you can try uploading a local file:

Photo.create(:image_url=>File.open("Path to local image file"))

from cloudinary_gem.

Fantastic! I tried this on a simper model and it worked. Looks like some of my method aliasing I use to detect image changes were conflicting. Thanks!
