Question

I’m trying to test a controller and I got this error. I understand the error, but don’t know how to fix it.

test: on CREATE to :user with completely invalid email should respond with    redirect (UsersControllerTest):ActionController::RedirectBackError:    No HTTP_REFERER was set in the request to this action,    so redirect_to :back could not be called successfully.  If this is a test, make sure to specify request.env['HTTP_REFERER']. 

Specify it where? I tried this:

setup { post :create, { :user => { :email => 'invalid@abc' } },    { 'referer' => '/sessions/new' } } 

But got the same error.

Specify it with what, exactly? I guess the URI of the view I want it to go back to:

'/sessions/new' 

Is that what they mean?

OK, so it turns out they mean do this:

setup do   @request.env['HTTP_REFERER'] = 'http://localhost:3000/sessions/new'   post :create, { :user => { :email => 'invalid@abc' } }, {} end 

Can someone tell me where that’s documented? I’d like to read up on the context of that information.

What if the domain is not ‘localhost:3000’? What if it’s ‘localhost:3001’ or something? Any way to anticipate that?

Why doesn’t this work:

setup { post :create, { :user => { :email => 'invalid@abc' } },    { 'referer' => '/sessions/new' } } 

The Rails docs specifically say that’s how you set the headers.

Their recommendation translates to the following:

setup do   @request.env['HTTP_REFERER'] = 'http://test.com/sessions/new'   post :create, { :user => { :email => 'invalid@abc' } } end
