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. Brian H. Web D.

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) : > **[PageResource.com - All About Web Development](https://pageresource.com)** > > PageResource.com is being discontinued as we’re merging with WebsiteSetup.org If you need web development tutorials, follow the links below (from WebsiteSetup.org) HTML Beginner’s Tutorial HTML Cheat Sheet How to Make a Website: Step by Step Guide If...
