Module: Formtastic::SemanticFormHelper

Defined in:
lib/formtastic.rb

Overview

Wrappers around form_for (etc) with :builder => SemanticFormBuilder.

  • semantic_form_for(@post)

  • semantic_fields_for(@post)

  • semantic_form_remote_for(@post)

  • semantic_remote_form_for(@post)

Each of which are the equivalent of:

  • form_for(@post, :builder => Formtastic::SemanticFormBuilder))

  • fields_for(@post, :builder => Formtastic::SemanticFormBuilder))

  • form_remote_for(@post, :builder => Formtastic::SemanticFormBuilder))

  • remote_form_for(@post, :builder => Formtastic::SemanticFormBuilder))

Example Usage:

<% semantic_form_for @post do |f| %>
  <%= f.input :title %>
  <%= f.input :body %>
<% end %>

The above examples use a resource-oriented style of form_for() helper where only the @post object is given as an argument, but the generic style is also supported, as are forms with inline objects (Post.new) rather than objects with instance variables (@post):

<% semantic_form_for :post, @post, :url => posts_path do |f| %>
  ...
<% end %>

<% semantic_form_for :post, Post.new, :url => posts_path do |f| %>
  ...
<% end %>

FIELD_ERROR_PROC =

Override the default ActiveRecordHelper behaviour of wrapping the input. This gets taken care of semantically by adding an error class to the LI tag containing the input.
