I am facing the following problem:
I am doing a Rails 4 webapp and we are using paperclip for profile images. If the user does not upload an image we provide a default one (like the facebook silhouette placeholder). So as paperclip eases handling default images, we are doing the following in the Profile model:
class Profile < ActiveRecord::Base
belongs_to :user
has_attached_file :image, :styles => { :medium => "300x300", :thumb => "100x100" }, :default_url => "assets/profiles/:style/placeholder.gif"
end
The big problem is that I need the complete URL of the image and NOT only the path so I am struggling to get the host and port before that path. Using action view helpers there did not help (asset_url helper)
I was thinking in initializing some constant or configuration or environment variable per environment. Will it be correct? Any other suggestions?
EDIT: I forgot to mention this: The resource (Profile) may have a custom picture or a default one. When it has a custom image, we store it in Amazon S3 and in that case profile.image.url returns full URL. In the other case, when it has not a custom picture it has a default image stored in app/assets/images and in that case profile.image.url returns just the path. I would like that the method image.url consistently return full URLs. – flyer88 just now edit
