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 %>

Constant Summary

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.

proc do |html_tag, instance_tag|
  html_tag
