Sorry if this is a FAQ but I couldn''t find anything on it:
I want to display a number in an input text_field. I want it to display
with commas, i.e. ''10,000''. I also want to allow the user to
enter
commas in the field. It''s a Float property in the model (could be a
Fixnum instead). If the user enters an invalid number in the form (i.e.
''a345'') I want to preserve the user''s input and
display an error.
What''s the best way to go about this? Do I do my conversions in the
controller? Do I add accessor methods in the model that get and set
strings? (That doesn''t seem very MVC-ish.)
Thanks!
Steve
