I have the following model

class Advertisement \< ActiveRecord::Base

# presence validation code

validates\_presence\_of :job\_title,  
:short\_description,  
:detail\_description,  
:contact\_email,  
:location,  
:area,  
:classification,  
:work\_type,  
:work\_place,  
:salary\_type,  
:min\_salary;

#length validation code  
validates\_length\_of :job\_title, :maximum =\> 80  
validates\_length\_of :short\_description, :maximum =\> 150  
validates\_length\_of :internal\_ref, :allow\_nil =\> true, :maximum =\>  
40  
validates\_length\_of :contact\_email, :maximum =\> 80  
validates\_length\_of :contact\_details, :allow\_nil =\> true, :maximum  
=\> 200

# numerical validation code

validates\_numericality\_of :min\_salary, :only\_integer =\> false  
validates\_numericality\_of :max\_salary, :allow\_nil =\>  
true, :only\_integer =\> false

# validate the format of data

validates\_format\_of :contact\_email,  
:with =\> /\A[\w.\_%-]+@[\w.-]+.[a-zA-Z]  
{2,4}\z/,  
:message =\> “is an invalid email address”

end

When I execute the following test case the second assert fails.

def test\_invalid\_ad\_with\_no\_attrs  
ad = Advertisement.new  
assert !ad.valid?  
assert ad.errors.invalid?(:min\_salary)  
end

Can anyone shed some light on this?

cheers
