    <p>I am writing a Rails 3.2.6 app. I want to separate my controllers and models into subfolders to keep my code clean. I have ensured that the model and its subdirectory name are not the same. However, I find that the code fails if the controller subdirectory name and the model subdirectory name are the same.</p> <p>The following application structure works fine:</p> <pre><code>test app controllers postcnt posts_controller.rb models postmdl post.rb </code></pre> <p>but the following structure doesn't:</p> <pre><code>test app controllers postnsp posts_controller.rb models postnsp post.rb </code></pre> <p>When I call the URL:</p> <pre><code>http://localhost:3000/postnsp/posts </code></pre> <p>I get a 500 error with the message:</p> <pre><code>LoadError in Postnsp::PostsController#index Expected /Users/dev/code/test/app/models/postnsp/post.rb to define Postnsp::Post </code></pre> <p>In the above examples I followed the advice here to eliminate model namespacing: <a href="https://stackoverflow.com/questions/1445341/rails-elegant-way-to-structure-models-into-subfolders-without-creating-submodul">Rails: Elegant way to structure models into subfolders without creating submodules</a></p> <p>and added</p> <pre><code>config.autoload_paths += Dir[Rails.root.join('app', 'models', '{**}')] </code></pre> <p>to my application.rb file </p> <p>For the second (failing) example the relevant files are as follows:</p> <p>post.rb:</p> <pre><code>class Post &lt; ActiveRecord::Base attr_accessible :content, :name end </code></pre> <p>posts_controller.rb:</p> <pre><code>class Postnsp::PostsController &lt; ApplicationController def index @posts = Post.all respond_to do |format| format.html # index.html.erb format.json { render json: @posts } end end </code></pre> <p>routes.rb:</p> <pre><code>Test::Application.routes.draw do namespace :postnsp do resources :posts end </code></pre> <p>Can anyone explain why the subdirectories can't be the same? I assume it's something to do with the creation of the postnsp module for the posts_controller.rb but I can't understand why it's preventing the creation of the model. I would like to have consistency in the directory structure naming in both the controller and model folders should I require it.</p>

    1. COI think it should be `class Postnsp::Post < ActiveRecord::Base` in the model .rb file too. (prefix `Postnsp`)

    2. COSee my response to Draiken below. Both examples above do not have namespaced models - one works, one doesn't. I don't want to change the model, rather I want to know what in the design of rails is preventing the second variant working.

    3. COProbably due to how auto loading works in Ruby. This is probably one of the areas where you are fighting against "the rails way" (good or bad, no comment!). But why do you want to separate into directories? What is it achieving for you apart from the "feeling of clean"? ("I have ensured that the model and its subdirectory name are not the same." => you've already fought against rails once, expect more!)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
