Is validates\_numericality\_of supposed to accept true as a value for  
the following options

class Location \< ActiveRecord::Base

validates\_numericality\_of :longitude, :allow\_nil =\>  
true, :greater\_than\_or\_equal\_to = -180, :less\_than\_or\_equal\_to = 180

end

place = Location.new()  
place.longitude = true  
assert place.save \<- succeeds!

What type is the longitude field? If it’s a integer field, setting true  
on  
it will make the value 1 and it will return true when you save it.

It’s a decimal field.
