Routes and REST Issue

Hi all,

A relative newcomer to routes here - I have a controller on which I would like to be able to specify only a couple RESTful operations (my example is for a RESTful user sessions controller, where it only makes sense to (1) create a session, and (2) destroy a session).

Using 'resources' on a controller in the routes file gives all seven methods so I'm not using that; I only need the two above, so my routes file looks like this:

    match 'sessions' => 'sessions#create', :via => :put     match 'sessions' => 'sessions#destroy', :via => :delete

Essentially I want a user to send a put (this is an idempotent operation) to the sessions collection URL, with a params hash of username and password. And calling delete on the same URL will log out the session.

However, my RSpec test, which looks like this:

describe "PUT 'new'" do     # (NB this user is created in the 'before' method)     it "should be successful" do       put 'new', {:name => 'a_user_logging_in', :password => 'a_password'}       response.should be_success     end

    it "should not be successful with a wrong username or password" do       put 'new', {:name => 'an_incorrect_user', :password => 'a_password'}       response.should_not be_success     end end

Does not pass as the routing fails! Here is the RSpec error:

Failure/Error: put 'new', {:name => 'a_user_logging_in', :password => 'a_password'}      ActionController::RoutingError:        No route matches {:name=>"a_user_logging_in", :password=>"a_password", :controller=>"sessions", :action=>"new"}

So clearly I've made an error here somewhere with my Routes, can someone help me achieve what I'm after (i.e. just a put and delete on a collection, which calls create and destroy on the controller?).

Many many thanks for your kind help,

- Nex

Hi all,

A relative newcomer to routes here - I have a controller on which I

would like to be able to specify only a couple RESTful operations (my

example is for a RESTful user sessions controller, where it only makes

sense to (1) create a session, and (2) destroy a session).

Using ‘resources’ on a controller in the routes file gives all seven

methods so I’m not using that; I only need the two above, so my routes

file looks like this:

match 'sessions' => 'sessions#create', :via => :put

match 'sessions' => 'sessions#destroy', :via => :delete

Making a create route does not give you a route for ‘new’ – you’ll need to create both.

You can also do:

resources :sessions, :only => [:new, :create, :destroy]

if you like.

You've routed put to the create action but in your spec you're calling the new action - the 2 need to match up.
