I'm working on a website that allows people who run bed and breakfast businesses
to post their accommodations.
I would like
to require that they include a "profile image" of the accommodation when they post it, but I also want
to give them the option
to add more images later (this will be developed after).
I thought the best thing
to do would be
to use the Paperclip gem and have a Accommodation and a Photo in my application, the later belonging
to the first as an association.
A new Photo record is created when they create an Accommodation. It has both id and accommodation_id attributes. However, the image is never uploaded and none of the Paperclip attributes get set (image_file_name: nil, image_content_type: nil, image_file_size: nil), so I get Paperclip's "missing" photo.
Any ideas on this one? It's been keeping me stuck for a few days now.
Accommodation
models/accommodation.rb
class Accommodation < ActiveRecord::Base
validates_presence_of :title, :description, :photo, :thing, :location
attr_accessible :title, :description, :thing, :borough, :location, :spaces, :price

end

Photo
The controller and views are still the same as when Rails generated them.
models/photo.erb
class Photo < ActiveRecord::Base
attr_accessible :image_file_name, :image_content_type, :image_file_size
belongs_to :accommodation
has_attached_file :image,
:styles => {
:thumb=> "100x100#",
:small => "150x150>" }
end
