Form submission type conversion

[Chris Booth]

I'm probably making this more complicated than it needs to be, but I'm
stumped.

I have a form with a regular text box for the user to enter a dollar
amount in. The model field for that box is a decimal. The model has
a validates_numericality_of for that field. If the user types
'$1,000.00' into the field and submits, the value gets put in as 0.

I've tried stripping the $ and , in a before_validation method using
self.<field>.to_s.gsub!('$',''), but this doesn't work, because
self.<field> is already set to 0 at this point.

Where would I strip the $ and , out of the value so that it will pass
the validates_numericality_of? Or should I even be using that
validation?

Worst case, you could write a custom validation for that.

I'd put a custom setter on the model and strip it there.

In my model I did something like:

before_validation :clean_phone_number

def clean_phone_number
    self.phone.gsub!(/\D/,'')
  end

to strip out the non-numeric stuff and then run the regular rails validation stuff.
