Question

SO,

I have been working on this for a while, I posted a much larger question that didn’t get any replies, but I’ll ask a much simpler one here.

My question is, how else can I assign something without using self.attribute = in the following context:

 def photo_from_url(url)
   remote_photo = open(url)
   def remote_photo.original_filename;base_uri.path.split('/').last; end
   **self.photo = remote_photo**
   self.save
 end

I need to make photo_from_url a class method so I can call it from delayed_job however when I add self, it gives me “no method found photo=”.

Please help! Thanks in advance…

Option 1: you want to create new object each time you call this method:

class Photo < ActiveRecord::Base
  def self.photo_from_url(url)
    ...

    new(:photo => remote_photo).save!
  end
end

Option 2: you want to update existing object, then you need to get object id you want to modify:

class Photo < ActiveRecord::Base
  def self.photo_from_url(url)
    ...

    id = # here you find id, e.g. from url 
    find(id).update_attributes!(:photo => remote_photo)
  end
end
