Formatting values of numbers using text_field

Rails
1

Anyone have a quick solution on how to format a number in a text_field
tag?

<% text_field “price”, “amount” %> returns 100.0 and it would be nice
if it showed 100.00

Of course, number_with_precision works nicely, but how do you make that
work with text_field?

I thought maybe overriding the getter in the model. However, this means
I would have to bring the helper code into the model which I’m not sure
I like.

If you mean formatting the field when the user exits the field, you
should use JavaScript (or write a small JavaScript Helper method, so
you can easily use it throughout your whole application) :

Yes, overriding the attribute getter and setter is what I do:

def amount_s
‘%.2f’ % amount
end

def amount_s= (amount)
self.amount = amount.to_f
end

<%= text_field :price, :amount_s %>
