Hi,
I wonder if anyone can help me. I'm having a problem with my request
specs.
I'm simulating a post in my specs thusly:
it "should check confirmation password" do
response = post(url(:account), { :account => {
:name => 'Name',
:email => '[email protected]',
:password => 'secret',
:password_confirmation => 'wrong',
}})
end
but this is generating an error "interning empty string" when I try to
call 'render' in the controller. This is because the :format param has
been set to "" rather than nil (or a valid format). The error
backtrace is this:

What appears to happen (though I have only a sketchy understanding of
what's going on) is that the code breaks my request down using the
router to generate an {:format => nil, :action =>
"theaction", :controller => "thecontroller"}.
:action and :controller get split out and used to instantiate and call
the right method on the right controller but :format gets merged into
the params. These params are encoded into a query string and sent,
through 'fake_request' as part of the post body. This results in
the :format being sent as a parameter:
..&format=&...
Which is then converted to an empty string by the controller, rather
than nil.
This empty string is what's causing the problem.
Now, I can fix this by simply removing the :format parameter from the
post body:
def build_request(params = {}, env = {})
params.delete(:format)
...
end
but this is obviously a hack.
The format parameter is dealt with correctly if I use webrat's
"click_button" to post a form, so what's the difference?
Has anyone else seen this? Is the problem in the way I'm calling the
post? I'm new to this kind of integration testing and making it up as
I go along. That might show..
Thanks in advance,
Garry
