Very strange routing error in rails 3 - ruby-on-rails-3

I got a controller called MeController. It has a bunch of actions like spaces and projects.
The spaces action does the following:
def spaces
#spaces = current_user.spaces
respond_to do |format|
format.html # show.html.erb
format.json { render json: #note }
end
end
The view just renders an other index template like:
<%= render :template => "spaces/index" %>
This works perfectly but now the stränge part begins... :S
This is the project action:
def projects
#projects = current_user.projects
respond_to do |format|
format.html # index.html.erb
format.json { render json: #projects }
end
end
The view renders also an index template:
<%= render :template => "projects/index" %>
But for the projects I get the following error:
Routing Error
No route matches {:action=>"edit", :controller=>"spaces", :id=>nil}
I just don't get why it should be an Routine Error with the action edit and the controller spaces. :/
Here are my routes:
# Profiles & Current User
resources :profiles
get "me" => "profiles#show", :as => "current_user"
get "me/spaces", :as => "current_user_spaces"
get "me/projects", :as => "current_user_projects"
get "me/tasks", :as => "current_user_tasks"
get "me/notes", :as => "current_user_notes"
get "me/discussions", :as => "current_user_discussions"
get "me/files", :as => "current_user_files"
# Permissions
resources :permissions
resources :spaces do
resources :projects do
resources :tasks
resources :notes
end
end
devise_for :users
root :to => redirect("/me/spaces")
Hope somebody has a hint for me! :)

So my guess would be:
In your template (projects/index), you are using url helpers like url_for or link_to with links to specific projects. The issue is that the projects have nested routing within your spaces resource. That's why you have to provide any url helper with a reference to both, space and project when you want it to generate an url to a project.
RoutingError is also thrown in case an url helper doesn't know how to construct an url.
This is a long shot, but I hope it helps.

respond_with location ignored on GET request

At each step in my checkout process, an order is updated via a PUT request. However, one of the states has a form that submits to a third party which redirects back to my site, calling the update method with GET (no control over this).
Why does my respond_with code appear to be totally ignored and I get a Missing Template checkout/update error? It should be hitting #edit.
CheckoutController.rb
before_filter :load_order
def update
if #order.update_attributes(params[:order])
#order.next
end
respond_with(#order, :location => checkout_state_url(#order.state))
end
routes.rb
match '/checkout/update/:state' => 'checkout#update', :as => :update_checkout
match '/checkout/:state' => 'checkout#edit', :as => :checkout_state
match '/checkout' => 'checkout#edit', :state => 'client_details', :as => :checkout
It looks like respond_with does different things depending upon the HTTP verb and whether the resource has errors. See here and here.
The following code worked for me:
def update
if #order.update_attributes(params[:order]) && #order.next
respond_with(#order) { |format| format.html { redirect_to checkout_state_url(#order.state) } }
else
respond_with(#order) { |format| format.html { render :edit } }
end
end

How to create a custom POST Action in Rails3

I am trying to create a custom POST action for my article object.
In my routes.rb, I have set the action in the following way:
resources :articles do
member do
post 'update_assigned_video'
end
end
In my articles_controller.rb I have:
def update_assigned_video
#article = Articles.find(params[:id])
#video = Video.find(:id => params[:chosenVideo])
respond_to do |format|
if !#video.nil?
#article.video = #video
format.html { redirect_to(#article, :notice => t('article.updated')) }
else
format.html { render :action => "assign_video" }
end
end
Then in my view I make a form like this:
<%= form_for #article, :url => update_assigned_video_article_path(#article) do |f|%>
[...]
<%= f.submit t('general.save') %>
The view renders (so I think he knows the route). But clicking on the submit button brings the following error message:
No route matches "/articles/28/update_assigned_video"
rake routes knows it also:
update_assigned_video_article POST /articles/:id/update_assigned_video(.:format) {:action=>"update_assigned_video", :controller=>"articles"}
What am I doing wrong?
Is this the wrong approach to do this?
Your form_for will do a PUT request rather than a POST request, because it's acting on an existing object. I would recommend changing the line in your routes file from this:
post 'update_assigned_video'
To this:
put 'update_assigned_video'

Unexpected dot from helper method

I have the following routings
PosTracker::Application.routes.draw do
get "home/index"
resources :pos
resources :apis
match 'update_data' => 'home#update', :as => :update, :via => :get
root :to => "home#index"
end
Now, when using the link_to helper method:
link_to "text", pos_path(starbase)
I get the following route /pos.13 instead of /pos/13. Obviously, this won't produce valid output. How can I fix this?
Edit: Relevant controller:
class PosController < ApplicationController
# GET /pos
# GET /pos.xml
def index
#do stuff
respond_to do |format|
format.html # index.html.erb
format.xml { render :xml => #pos }
end
end
# GET /pos/1
# GET /pos/1.xml
def show
#pos = Pos.find(params[:id])
respond_to do |format|
format.html # show.html.erb
format.xml { render :xml => #pos }
end
end
end
It seems to me like Rails is recognizing pos_path as your #index action url helper. Generally it will take the symbol you pass to resources and singularize it for a #show action.
The url helper you want to use would be
link_to "text", po_path(starbase)
You can generally find the name of the helper methods by running
rake routes
Or to get the helper for a specific controller
rake routes CONTROLLER=pos

Rails 3: Problem with a route to new action

I have a problem with rails 3 routes.
I want add a new action called "gestion_etudiant" with a new view "gestion_etudiant.html.erb".
I have on my index page a link like this
<%= link_to "Administration", {:controller => "users", :action => "gestion_etudiant"} %>
I also try this:
<%= link_to "Administration", "/users/gestion_etudiant" %>
In my controller:
def gestion_etudiant
#users = User.find(:all)
end
but when I clic on the link, I always have this error:
ActiveRecord::RecordNotFound in UsersController#show
Couldn't find User with ID=gestion_etudiant
I have this in my routes file:
resources :users
And I've also try to add:
match "users/gestion_etudiant", :to => "users#gestion_etudiant"
and
resources :users, :only => [:gestion_etudiant]
But I can not access my page "gestion_etudiant.html.erb". Can anybody suggest why?
Try this:
# router:
resources :users do
get :gestion_etudiant, :on => :collection
end
# view:
link_to "Administration", gestion_etudiant_users_path
# Controller
def gestion_etudiant
#users = User.all # Don't use find with :all as it will be deprecated in rails 3.1
end
In your routes, try:
resources :users do
collection do
get 'gestion_etudiant'
end
end
You can check the routes you have in your application by running rake routes

Rails 3 - Nested Resources Routing - One to One relationship

Having some trouble with some nested resources routing. What I'm trying to do is link to a user's profile page for editing purposes. In my view it is written as:
<%= link_to "Edit Profile", edit_user_profile_path(current_user) %>
Which errors out with:
No route matches {:action=>"edit", :controller=>"profiles", :user_id=>#<User id: 1, email: "EDITEDOUT", hashed_password: "EDITEDOUT", created_at: "2011-01-20 18:30:44", updated_at: "2011-01-20 18:30:44">}
In my routes.rb file, it looks like so:
resources :users do
resources :profiles, :controller => "profiles"
end
I checked my Rake routes, and it gave me this as a valid option:
edit_user_profile GET /users/:user_id/profiles/:id/edit(.:format) {:action=>"edit", :controller=>"profiles"}
Which I am able to manually navigate to. For good measures, here's proof of my controller:
class ProfilesController < ApplicationController
def edit
#user = current_user
#profile = current_user.profile
end
def update
#user = current_user
#profile = current_user.profile
respond_to do |format|
if #profile.update_attributes(params[:profile])
format.html { redirect_to(orders_path, :notice => "Your profile has been updated.") }
format.xml { head :ok }
else
format.html { render :action => "edit" }
format.xml { render :xml => #profile.errors, :status => :unprocessable_entity }
end
end
end
end
Anyway, I've been having some problem tracking this down. Any pointers would help. For my DB design Profiles belong to Users in a one-to-one relationship. I'm hoping it's just something newbish I'm not noticing a new set of eyes might help.
If you look closely at your route, you'll see that it expects both a :user_id and an :id. The latter, in this case, refers to the user profile.
In order to tell Rails that you want that particular profile, you'll have to specify both the user and the profile in your link, like this:
edit_user_profile_path(current_user, #profile)
Now, Rails will use the first argument (current_user) for the :user_id part of the route, and the second argument (#profile) for the :id.
