Carrierwave get image by url

I need to get some images by the url.

The urls are like http://img.wallsbay.com/large/2014/05/2665.jpg but 2014 and 2665 are changings.

My controller has this params:

  def image_params
    params.require(:image).permit(:content, :remote_content_url, :id)
  end

And i tried to get image from the url like this:

@image.remote_content_url = 'http://img.wallsbay.com/large/#{:content}/05/#{:id}jpg'

but remote_content_url is undefined method.

I resolve this issue by adding attr_accessor :remote_content_url into my image model.

The remote_<attr_name>_url attribute is to upload images by a given URL.

@model.remote_content_url = "http://img.wallsbay.com/large/2014/05/2665.jpg"
@model.save
@model.content_url // => "<upload-dir>/2665.jpg"

Use @model.content_url to retrieve the url to the uploaded image.

To apply a transformation use @model.content_url(:square).

The correct way to get the image URL would be @image.content.url assuming content is the attribute you are using for Carrierwave.
