Re: [ORUG] Form submission type conversion

[Scott Moe]

I had a similar problem with money fields.  I kept the the validates_numericality_of
so a type cast "0" will not validate.

The garbage entered by the user is still available with object.attributes_before_type_cast[field_name]. In a rather overdone view helper method I build an input tag with the value set to what the user typed, if object.errors.on field_name is true.  I'm willing to show you the code but the error handling is a small part of that mess. Those ActiveRecord methods may be all you need.

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?
