rspec users - Mar 2009 - Spec::Rails, "model.should have(1).error_on(:attribute)" passes when?

Spec::Rails people,

I''m curious about:
  - model.should have(1).error_on(:attribute)

displayed in the URL below:
 
http://rspec.rubyforge.org/rspec-rails/1.2.2/classes/Spec/Rails/Extensions/ActiveRecord/InstanceMethods.html

The Rspec peepcode screencast suggests that
model.should have(1).error_on(:attribute)
should pass if
model.send(:attribute)
returns nil

For me, I get an exception from the rspec script.

My work-around is simple.

Instead of:
  - model.should have(1).error_on(:attribute)
I Use:
  -model.send(:attribute).should be_nil

But now I have the question:
  - What kind of error causes:
    - model.should have(1).error_on(:attribute)
    - to pass ??

--b

If you add this to your model:

  validates_presence_of :attribute

Then this will pass

  Model.new(:attribute => nil).should have(1).error_on(:attribute)

I added:
  - validates_presence_of :attribute

To my model.

The test now passes.

Thanks David.

Congrats! It took longer than it usually does, but you just  
experienced the red and green parts of the red/green/refactor cycle.
