Rails and decimals problem

rubyonrails-talk

Hi,

I was working on a plugin to enhance ActiveRecord's models so that it's easy to handle decimal numbers and store them as integers. I was dynamically creating instance methods to output the formatted attribute (145 becomes 14.5)

Now there is a problem with Rails forms (for example), as they access the attributes with instance_variable_get.

So to intercept that call, should I use alias_method_chain?

Regards

Ok so I've dropped work on the plugin and used decimal in rails migration to aset the column type accordingly.

But now, 130 appears as 130.0 , which is ugly and could lead people to misinterpret the a price as $1300. Is there an easy way to get rid of trailing zeros?

Regards

There is a helper method called "number_to_currency" that allows you to set precision, unit ++ http://api.rubyonrails.org/classes/ActionView/Helpers/NumberHelper.html#M001684
