Hi,
I have this in one of my models:
validates_format_of :amount, :with => /\A[0-9]{1,5}\.[0-9]{2}\Z/
If I enter an amount that ends with ".00", eg. 123.00 or 300.00 it
fails, and I cannot understand why. It works with 123.11 or 300.01,
etc.
I have also tried:
validates_format_of :amount, :with => /\A[0-9]{1,5}\.[0-9][0-9]\Z/
but it gives the same result (ie. doesn''t work as I would have thought
it would).
Am I missing something?
I''m using JRuby on Netbeans under Windows Vista if that is relevant.
Andrew.

Try telling ruby that a variable contains the value 300.00, it will say:>> a = 300.00=> 300.0>> a=> 300.0 And there''s your answer. You will have to tell Ruby that this is a so- called "double". to_d didn''t work in my local environment, but that Ruby version is quite old. Try to to find how to convert your object into a double. Hope this helps!

Right, as I said, I''ve never done something like it, but at least we know what''s wrong.

Thanks all for your suggestions. It''s definitely dropping the final
"0"
as Jaap suggested.
I think I can work around it by changing the regular expression to:
/\A[0-9]{1,5}\.[0-9]{1,2}\Z/
Also just as a side note I''m new to Ruby / Rails having previously
worked with ColdFusion and Java, and I have to say this is a really
helpful community on this list. Great stuff.

Great stuff.I''m a former CF developer myself. If there''s any way that I can provide Rails insight on something CF-related, please feel free to ask.

Conrad Taylor wrote: [...]> validates_numericality_of only determines whether something is numericThat''s true. And that may be all that the OP really needs here, which is why I suggested it.

But \d is 2 characters instead of 5, and I believe that is the better choice from a readability standpoint.
