Nested Resource w/ Collection

Hi guys,

In my routes file I have the following nested resource:

  resources :users do
      collection do
        get ''posts''
      end
    end

However, when I visit this URL: http://localhost:3000/users/posts, I get this
error:  "The action ''posts'' could not be found for
UsersController"

In my UsersController I have the following:

class UsersController < ApplicationController
  # GET /users
  # GET /users.json
  def index
    @users = User.order(:name)

    respond_to do |format|
      format.html # index.html.erb
      format.json  { render :json => @users }
    end
  end

  # GET /users/1
  # GET /users/1.json
  def show
    @user = User.find(params[:id])

    respond_to do |format|
      format.html # show.html.erb
      format.json  { render :json => @user }
    end
  end

  # GET /users/new
  # GET /users/new.json
  def new
    @user = User.new

    respond_to do |format|
      format.html # new.html.erb
      format.json  { render :json => @user }
    end
  end

  # GET /users/1/edit
  def edit
    @user = User.find(params[:id])
  end

  # POST /users
  # POST /users.json
  def create
    @user = User.new(params[:user])

    respond_to do |format|
      if @user.save
        format.html { redirect_to(users_url,
          :notice => "User #{@user.name} was successfully
created.") }
        format.json  { render :json => @user,
          :status => :created, :location => @user }
      else
        format.html { render :action => "new" }
        format.json  { render :json => @user.errors,
          :status => :unprocessable_entity }
      end
    end
  end

  # PUT /users/1
  # PUT /users/1.json
  def update
    @user = User.find(params[:id])

    respond_to do |format|
      if @user.update_attributes(params[:user])
        format.html { redirect_to(users_url,
          :notice => "User #{@user.name} was successfully
updated.") }
        format.json  { head :ok }
      else
        format.html { render :action => "edit" }
        format.json  { render :json => @user.errors,
          :status => :unprocessable_entity }
      end
    end
  end

  # DELETE /users/1
  # DELETE /users/1.json
  def destroy
    @user = User.find(params[:id])
    @user.destroy

    respond_to do |format|
      format.html { redirect_to(users_url) }
      format.json  { head :ok }
    end
  end
end



What would I change for the route:  http://localhost:3000/users/posts to work?

> "The action ''posts'' could not be found for

http://localhost:3000/users/posts

routes your request to UsersController#posts, but method
''posts'' is not
there.

Add ''posts'' method to UsersController, and your problem is
solved.

Or... you have just created a whole load of different problems... :-/


Instead, check the result of "rake routes" to see what routes Rails is
expecting - this might put you on the track towards what is not right
with your routing.

PS Just to clarify, rather than "collection" you possibly want to use
the syntax:
  resources :users do
    resources :posts
  end

Re: Nested Resource w/ Collection

Michael,

I initially I was using resources as oppose to collection.  I ran take routes
and users/posts is a valid route.

Ultimately I am trying to keep a relationship between the two models but remove
the user id from the URL.

You can keep a relationship between models without *any* nesting of
routes. Whether a Post belongs to a User, or has many Comments has no
*requirement* for certain routes. The routes are just there to help
you get about those relationships.
What exact functionality do you want to implement?

Re: Nested Resource w/ Collection

The end goal is this:  I have a client app that is proxing json from the rails
server.   Our current way of using /users/id/posts.json as the url proxied does
not work as needed.  I would like to set a relation between the user and post
model but NOT have a nested url.  The desired scenario is this: A user logs in
and creates a session.  After authentication a redirect to /posts occurs.  Post
belongs to user and user has_many posts.

If you''d like and have a git account, I can add you as a contributor to
this demo.  This way you can see and change the logic I have currently.  Here is
a link to the git project: https://github.com/TheCodeBoutique/Blogger
