A useful form helper to provide an easy to use colour picker field. Using this plugin you can simply provide a colour field with an integrated javascript colour picker.

Installation Instructions

1. Install the plugin into your Rails application

./script/plugin install http://svn.plasticrain.com/stuff/rails/plugins/colour_picker

This will automatically copy some required resources into the appropriate locations. The colour_picker.js file which powers all the javascript actions will be copied into public/javascripts. Also, a new folder will be created in your public/images folder to contain two required images – a spacer and alternative button icon.

You need to include the javascript in your application’s layout.

<%=javascript_include_tag 'colour_picker'%>

Within your form, simply call the ‘colour_field’ method:

<%=colour_field :object, :method%>

Usage Examples

Use the colour field with a graphical swatch icon rather than a button:

<%=colour_field :object, :method, :use_swatch_icon => true%>

Change the label of the default button:

<%=colour_field :object, :method, {}, {:value => 'Choose a colour' }%>
