Thanks, first, to everyone who's asked and answered questions on this list,
and to the creators of RSpec - it is all very helpful. I've searched the
mailing list, and had a couple 2hr googling sessions that didn't help me
find an answer.
I've run into a problem getting my first non-trivial view spec to run. I
get an error when trying to generate a link_to() to another resource. Here
is an overview of the situation, then the code:
- I'm using a restful design
- I'm using nested (multiply nested) resources
- I am trying to test a show.rhtml view, that includes links (link_to)
to resources managed by another controller
- The use_case model has a many-to-may through relationship with
actors, and I'm displaying links to the associated actors on the use_case
page
- I can't get the links to generate when running rspec (but it works
great in the app)
- I am in the early stages of the project, and want to move forward
BDD, but I have some existing code that I need to test before I can start
moving forward again.
My theories: I need to stub the controller (for the other resource), or I
need to stub something else.
Here's the command I'm running to drive RSpec
ruby script/spec -f s spec/views
Here's the error that I get
1)
ActionView::TemplateError in 'UseCase showing a use case should display the

Here's part of my routes.rb, showing the nested resources
map.resources :customers do |customers|
customers.resources :projects do |projects|
projects.resources :actors
projects.resources :use_cases
Here's some of the stubbing that I am using to set up the spec
@customer = mock_model(Customer,
:id => 1,
:to_param => "1"
)
@project = mock_model(Project,
:id => 1,
:customer_id => 1,
:to_param => "1"
)
I've also stubbed objects to create the following :assigns
assigns[:customer] = @customer
assigns[:project] = @project
assigns[:use_case] = @use_case
assigns[:primary_actors] = @primary_actors
I suspect that there is something else that needs to be stubbed - actors
controller, maybe? I really don't know. If anyone can point me in the
right direction, or tell me where in the error message to dig deeper, that
would be awesome.
If I left out any important information, please let me know! And a huge
thanks in advance to anyone who can help me out, or explain why this isn't
supported, or point me towards any docs or articles that address this issue
(because I will have it a zillion times, as almost all views in my app
display content and links from more than one model).
