I was trying to access rails functions (number_with_precision) from an irb session. It can''t find the method. How do I load the libraries ? TIA LS -- Posted via http://www.ruby-forum.com/.

I normally use number_with_precision in my views and I''ve never had a problem. Now however, I need to use it in my controller because my Ajax method is calling the controller and the controller will return values to it which will be displayed in the span of my html document. In short, what am I doing wrong in the stateme...

Hello I''ve encountered a little problem with zeros using the decimal data type Specifying a scale of 3 and inserting a number with 3 zeros after the point (for example 12345.000) it gets correctly stored in the database, but rails insists to show me the number only with the first zero after the point (12345.0) There is a way to tell rails to not truncate at the first zero?

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.

I tracked down the error and saw that editing line 89 ( number_to_currency method) as follows solved the problem : Old piece of code : begin format.gsub(/%n/, number_with_precision(number, :precision => precision, :delimiter => delimiter, :separator => separator) ).gsub(/%u/, unit) rescue number end New one : begin format.gsub(/%n/, number_with_precision(number, :precision => precision, :delimiter => delimiter,...

I work in the UK and therefore most of my currency figures will be in UK pounds. I realise that to format a number to a currency format I can use: number_to_currency(amt, :unit => "?") but it would be more convenient to set ? as the default currency symbol. What is the best way to do that? Should I edit line 39 of this file:
