Re: params not available for controller specs?

Ah, thanks! That was a breakthrough. My mock object “ids_string” isn’t
receiving the method calls I expect (even though the code under test
actually does what I want it to do and works correctly), but at least
I’m past the params issue.

Try:
get :download, :ids => ids_string

You need the “:” in front of the action name.

Hi, all,

I’m trying to write a spec for a controller method that starts out:

def download
@orders = Order.find( params[:ids] )

and started writing a spec that set params[:ids] to a mock.

Why would you want to set params[:ids] to a mock? params values are
always basically strings (or hashes/arrays of strings) and you can set
them in the actual action call:

get :foo, :ids => [1,2,3]

Moreover, in your case Order.find should be the thing you want to
stub. You don’t want the finder call to go to the database, since
you’re speccing the controller behaviour here, not business logic.

You don’t get the same object through the action queue, which is
another reason for not mocking something there. “string 1” is not
necessarily the same object as “string 1” and Rails will do a lot of
processing to the parameters before they end up in the params hash.

Just assume that a similar string will get passed through and spec
that the behaviour is what you expect.

What kind of method calls are you expecting/stubbing for a string?
