Rails namescoped model object without module prefix route path

Question

i have problem little bit with Rails router and form generator. My application have namespaced modules for models and controllers. Module is used to easier abstraction to another projects.

I using in routes.rb scope method instead namespace, because i wan't have "ugly" path helpers.

It looks like:

scope module: :taxonomy do
  resources :taxonomies do
    resources :terms
  end
end

Problem is that when i want to edit taxonomy (url: taxonomies/1/edit) i get an error:

undefined method `taxonomy_taxonomy_path'

cause my route is instead only taxonomy_path

is there any way how reach form_for @taxonomy to recognize that route is scoped? without used form_for @taxonomy, url: taxonomy_path(@taxonomy) which is not cure. Because @taxonomy object in controller methods within respond_with @taxonomy always refereces to taxonomy_taxonomy_url

my models:

module Taxonomy
  class Taxonomy < ActiveRecord::Base
    has_many :taxonomy_terms, inverse_of: :taxonomy
    has_many :terms, through: :taxonomy_terms
  class Term < ActiveRecord::Base
    has_one :taxonomy_term, inverse_of: :term
    has_one :taxonomy, through: :taxonomy_term

and controllers:

module Taxonomy
  class TaxonomiesController < ApplicationController

Answer 1

You can override ActiveRecord's model naming by:

module Taxonomy
  class Taxonomy < ActiveRecord::Base
    def self.model_name
      ActiveModel::Name.new("Taxonomy")
    end
  end
end

This overrides ActiveRecord default naming generation which generates taxonomy_taxonomy name for the Taxonomy class since it is under Taxonomy module. It should solve your routing name problem and generate a proper route name as you wish.

Answer 2

Try this in routes.rb:

namespace :taxonomy do
  resources :taxonomies do
    resources :terms
  end
end

This will probably require you to store your controllers in a subdirectory named taxonomy as well.

Answer 3

I am pretty sure you need to add a Module to your Class because of your folder structure.

  app/models
  ├── ...
  ├── taxonomy
  │   ├── taxonomy.rb
  │   └── ...
  └── ...

---

You can config rails to load your models located in subfolders recursively:

Config your config/application.rb:

config.autoload_paths += Dir[ Rails.root.join('app', 'models', "taxonomy", '**/') ]

You can set this config for any folder and subfolder in your rails app.

If you do that you will not have to override an ActiveRecord's model, which is not always the best idea.

class Taxonomy < ActiveRecord::Base
  ...
end
