Ruby on Rails Plugins

form_helper_css

This plugin enhances the default tag helpers to automatically add CSS classes to form elements. It’s similar to the enhanced_form_tag_helper plugin, but takes a different approach by directly intercepting the tag and content_tag methods, and should therefore work in all situations where form elements are created, especially the FormHelper and more exotic ones like button_to.

The following elements are enhanced:

• <input> tags get their type as class name
• submit buttons additionally get the class name button
• password fields additionally get the class name text
• <textarea> tags get the class name text
• <select> tags get the class name select
• <button> tags get the class name button

If any helper options already specify a class, nothing will be changed. If you don’t want a class to be added, pass :class => nil.

Installation

script/plugin install -x http://dev.diarrhea.ch/svn/rails_plugins/trunk/form_helper_css

redcloth_template

This plugin registers a template handler for *.red files, which will be run through ERB and RedCloth, and enables you to use Textile syntax directly in your views.

Note: this plugin requires at least RedCloth 4.0 (aka "SuperRedCloth").

Installation

script/plugin install -x http://dev.diarrhea.ch/svn/rails_plugins/trunk/redcloth_template

auto_convert_fields

This plugin lets you define model fields which should be automatically converted with helpers from the TextHelper module, or a custom block. It works by redefining the field= method, so it applies immediately. If you already have a custom setter, it will be aliased and called after the conversion. You can also use the old (or default) setter explicitly by calling field_without_auto_convert=.

Usage

Use the class method auto_convert to specify fields, and pass symbols for the helpers in the :with option:

class MyModel < ActiveRecord::Base
  auto_convert :name, :text, :with => :strip_tags
end

You can specify multiple helpers by passing an array. The helpers will be run in the order they’re specified in:

class MyModel < ActiveRecord::Base
  auto_convert :name, :text, :with => [ :strip_tags, :simple_format ]
end

For more complex cases, pass a block which will be given the value. The helpers are also available in the context of the block:

class MyModel < ActiveRecord::Base
  auto_convert :name, :text do |value|
    strip_tags(value).strip.gsub(/[^\w ]/, '')
  end
end

Installation

script/plugin install -x http://dev.diarrhea.ch/svn/rails_plugins/trunk/auto_convert_fields
