Functional tests of nested routes on Rails 3
I have a Rails 3 app with the following nested route:
resources :games do
collection do
get :all
get :unassigned
end
resources :messages
resources :comments
end
A Game has many comments, and a Game also has many messages.
I am expecting that "/games/1/comments" routes to the index action on the 开发者_StackOverflow社区comments controller, and sets :game_id => 1
in the params hash.
Everything is working fine in the app. However, my route tests are failing and I can't figure out why.
When I try this:
assert_routing({:path => "/games/1/messages", :method => :get},
{ :controller => "messages", :action => "index", :game_id => 1})
I get this:
2) Failure:

When I try this (note the quoting on :game_id
) :
assert_routing({:path => "/games/1/messages", :method => :get},
{ :controller => "messages", :action => "index", :game_id => "1"})

Also tried this:
assert_routing({:path => "/games/1/messages", :method => :get}, {:controller => "messages", :action => "index"}, {}, {:game_id => "1"})
Response:
The recognized options <{"action"=>"index", "game_id"=>"1", "controller"=>"messages"}>
did not match <{"action"=>"index", "controller"=>"messages"}>, difference: <{"game_id"=>"1"}>
I think, somehow, I'm getting hung up on the syntax for testing the routing on nested resources. Any ideas?
Thanks in advance--
Assert routing does two things (in that order)
assert_recognizes
assert_generates
So your test-case 2 gets one step further / performs better.
Now, assert_generates
checks whether url_for
returns the url you give it.
url_for(:controller => "messages", :action => "index", :game_id => "1")
# should return: /games/1/messages
But according to the exception, it returns /messages?game_id=1
(game_id
as the extra). This should/can only happen, if you have a resources :messages
rule before your resources :games
. If that's the case, move it behind, so that the nested rule comes first.
Try
assert_routing({:path => "/games/1/messages", :method => :get}, {:controller => "messages", :action => "index"}, {}, {:game_id => "1"})
