ClassyFieldErrors

Purpose

Provide clean html/css handling of form fields with errors. Rails wraps error input fields with a div, to provide styling. We just add the css class directly to the error form field.

Why

The default rails way can break html structure, and destroy placement/styling. We saw this happen mainly when you wrap form fields inside label tags.

Result

Normal Rails html/css for error input fields

<div class="fieldWithErrors"><input>Test</input></div>

New output

<input class="input-error">Test</input>

This works on input, textarea and select elements.

How to use

  • Install the plugin: script/plugin install git://github.com/xing/classy_field_errors.git

  • Put the css contained in sample/field_error_proc.css in your base css file
