Spec'ing the result of rescue_from

Testing RSpec
1

Hey All,

In my app, I have actions that are restricted to only POST requests in
config/routes.rb. We were getting a fair number of MethodNotAllowed
errors on these actions. In most cases, we’re ok with sending the
user back to the homepage, however there are a few exceptions where
we’d like to send them a specific action. My spec looks like this:

describe “GET process_step_2” do
it “should redirect to step_2” do
rescue_action_in_public!
get :process_step_2
response.should redirect_to(application_step_2_url)
end
end

Then my application controller, I decided to rescue_from, so it looks
like this:

class ApplicationController < ActionController::Base
rescue_from ActionController::MethodNotAllowed, :with
=> :invalid_method

protected

def invalid_method
redirect_to previous_step_url
end

def previous_step_url
case request.env[“REQUEST_URI”]
when /step_2/process/
application_step_2_url
else
root_url
end
end
end

The spec fails even though when you re-create the situation in the
browser, the code works.

What am I doing wrong here? Am I even going about this in the right
way?

Thanks in advance for your help.

Best, PJ

What’s the failure message?

I guess the question then, is that if this is how things are handled
when using rescue_from, how do I spec out that users are being
redirected to the right location? Do you think the inconsistency
between the development test logs needs to be brought up with Rails
core?

You’ve got a route named application :slight_smile: I’m sure that’s where the
confusion lies, though I’m not convinced of where the problem lies.

What are the controllers and models actually called? What version of
rails, rspec, etc?

Hi David, thanks for the speedy response yesterday. Much appreciated.

I did some more digging, and found a couple things. When I try this
in the browser (by visiting /application/step_2/process) and look at
the development log, the request is actually being made to
ApplicationController#index:

Processing ApplicationController#index (for 127.0.0.1 at 2009-06-23
11:08:18) [GET]
Redirected to http://byassociation.local/application/step_2

However when the specs are run, the test log shows:

Processing MembersController#process_step_2 (for 208.77.188.166 at
2009-06-23 11:19:50) [GET]
