  • Formtastic: Forms Made Crazy Easy for Rails Developers

    html-forms.pngFormtastic is a Rails plugin by Justin French that aims to take the headaches out of building forms in Rails views. To build it, Justin wrote down how he'd like a form creation DSL to look and then worked backwards to building the code necessary to implement that DSL. The result is a very obvious and straightforward form creation DSL.

    Formtastic doesn't just make it easy to whip up basic forms, though. It has some significant advantages over similar plugins:

    • It's Rails 2.3 ready
    • It's under active development (the last update was yesterday)
    • It supports internationalization
    • It has full spec coverage
    • It can handle belongs_to, has_many, and has_and_belongs_to_many associations out of the box, rendering multi-selects and radio inputs where necessary!
    • It doesn't screw around with the existing Rails form helpers

    Here's a large form example straight from Formtastic's documentation (which is pretty thorough, you'll be glad to know):

    <% semantic_form_for @article do |form| %>
    
      <% form.inputs :name => "Basic" do %>
        <%= form.input :title %>
        <%= form.input :body %>
        <%= form.input :section %>
        <%= form.input :publication_state, :as => :radio %>
        <%= form.input :category %>
        <%= form.input :allow_comments, :label => "Allow commenting on this article" %>
      <% end %>
    
      <% form.inputs :name => "Advanced" do %>
        <%= form.input :keywords, :required => false, :hint => "Example: ruby, rails, forms" %>
        <%= form.input :extract, :required => false %>
        <%= form.input :description, :required => false %>
        <%= form.input :url_title, :required => false %>
      <% end %>
    
      <% form.inputs :name => "Author", :for => :author do |author_form| %>
        <%= author_form.input :first_name %>
        <%= author_form.input :last_name %>
      <% end %>
    
      <% form.buttons do %>
        <%= form.commit_button %>
      <% end %>
    
    <% end %>

    The result is a clean bundle of HTML. Groovy, right? So get reading the documentation and give it a try. It's an awesome plugin.
