Issue when using with responders #155

Closed d3crypt3d closed 8 years ago

d3crypt3d commented 8 years ago

When I try to use a model instance with responders the controller raises an error: NoMethodError: undefined method `texts_url'

# app/models/text.rb
class Text
  include ActiveAttr::Model

  attribute :plain
  attribute :encrypted
  attribute :frequency
end

# app/controllers/crypt_controller.rb
class CryptController < ApplicationController
   respond_to :json

  def encrypt
    respond_with Text.new(plain: @text, encrypted: output, frequency: frequency_analisys(output)), status: :ok
  end
  # ...
end

ERROR NoMethodError: undefined method texts_url' for #<CryptController:0x000000074745f8> /home/workstat/.rvm/gems/ruby-2.1.4@rails4/gems/actionpack-4.2.5.1/lib/action_dispatch/routing/polymorphic_routes.rb:220:inpolymorphic_method' /home/workstat/.rvm/gems/ruby-2.1.4@rails4/gems/actionpack-4.2.5.1/lib/action_dispatch/routing/polymorphic_routes.rb:114:in polymorphic_url' /home/workstat/.rvm/gems/ruby-2.1.4@rails4/gems/actionpack-4.2.5.1/lib/action_dispatch/routing/url_for.rb:164:inurl_for'

I'm not sure why anything would be trying to create a URL from just this sample code. Can you provide the full backtrace?

The reason this is happening is because the request is a POST, which the responders gem assumes is used for creating a resource and, like would be created when generating a Rails scaffold controller in a create action, the responders gem is trying to communicate the Location header for the resource and that's where it's trying to generate a URL for the given model. However there isn't a resources route defined for your Text model and that's why it fails. You could override the :location option if you have something suitable, but if not then the responders gem is probably too generalized for your use case.

      elsif post?
        display resource, :status => :created, :location => api_location
