The above is not how you want to write that spec.
Do something like this instead:
--------------------------
describe DrugsController do
it "assigns the drugs within a given category as @drugs" do
Drug.stub!(:where).with([ 'drug_category_id = ?', "37"
]).and_return([ mock_drug ])
get :search, :id => "37"
assigns[:drugs].should equal([ mock_drug ])
end
private
def mock_drug(stubs={})
@mock_drug ||= mock_model(Drug, stubs)
end
end
--------------------------
Note: I think the syntax for assigns has changed somewhat in RSpec 2.0
so you may want to read about that change. What I've shown here is RSpec
1.x syntax.
You don't need to hit the database just to make sure your controller is
assigning the @drugs instance variable. Use a mock instead. You don't
need to test the Rails "where()" method. Hopefully, that already has its
own tests in Rails. If it were broken, it doesn't do you any good to
prove it's broken in your application specs anyway.
