Namespaces route and model path rails

I'm just started with rails and until now I was very happy with it, but there is one thing I can't figure out.

I have some ActiveRecords models in a namespace "Monitor", and I have some controllers in a Namespace "Settings". What I want to accomplish is that I can use the namespaced models in my settings controllers/forms.

I've got this:

/config/routes.rb

namespace :settings do
  resources :queues, :channels
end

/app/controllers/settings/queus_controller.rb

class Settings::QueuesController < ApplicationController

  def new
    @queue = Monitor::Queue.new()
    render 'form', :layout => false
  end

  def create
    @queue = Monitor::Queue.new(post_params)

    if (@queue.save)
      @status = 'added'
      render 'success'
    else
      render 'form', :layout => false
    end
  end

  def edit
    @queue = Monitor::Queue.find(params[:id])
    render 'form', :layout => false
  end

  ...
end

/app/models/monitor/queue.rb

module Monitor
  class Queue < ActiveRecord::Base
  end
end

/app/views/settings/form.html.erb

<%= form_for @queue do |f| %>
  ...
<% end %>

Now Rails is complaining about a missing method : monitor_queues_path or Rails generates a path like /monitor/queues instead of /settings/queues(:new/edit).

What am I missing here?

I found a solution from my friend @mkhairi he said to use this on the parent model :

class YourParentModel < ApplicationRecord
      def self.use_relative_model_naming?
        true
      end
end

then you can use back ur lovely short path.

Aah I found it!

This post gave me the proper solution: Rails namescoped model object without module prefix route path

The problem came from the prefix from the ActiveRecord class:

module Monitor
  class Queue < ActiveRecord::Base
  end
end

This should be

module Monitor
  class Queue < ActiveRecord::Base
    def self.model_name
      ActiveModel::Name.new("Monitor::Queue", nil, "Queue")
    end
  end
end

After changing this I only needed to change the form_for in the correct way:

<%= form_for [:settings, @queue] do |f| %>

And that fixes it :D

You are using nesting for your Queue models. Therefore your form_for call needs to know about the parent model too. So in your case you nested Queue under Setting so you will need to provide a setting object as well. I'm guessing in your controller you made a @setting variable. If this is the case then the following code will work for you.

<%= form_for [@setting, @queue] do |f| %>
    <%# Your form code here -%>
<% end -%>
