You must have mis-read. I said that validates_numericality_of also
exhibited this:
| I've never worked at two places that had the same validation rules.
To illustrate:
{ :greater_than => 2 }
Is a different validation rule to
{ :less_than => 10 }
But nonetheless, the *core* of the matter is that the format for "a
number" does not change - the subset of values you permit does.
In the same way,
{ :domain_in => /\.edu\./ }
Would be a different validation rule to
{ :domain_in => /\.jp$/ }
But nonetheless, the *core* of the matter is that the format for "an
email address" does not change - the subset of values you permit does.
I hope you can see the parallels.
