Module: Netzke::Basepack::FormPanel::Fields

Extended by:
ActiveSupport::Concern
Defined in:
lib/netzke/basepack/form_panel/fields.rb

Overview

Because FormPanel allows for arbitrary layout of fields, we need to have all fields configured in one place (the fields method), and then have references to those fields from items.

Defined Under Namespace

Instance Method Details

#fields ⇒ Object

Hash of fully configured fields, that are referenced in the items. E.g.:

{
  :role__name => {:xtype => 'netzkeremotecombo', :disabled => true, :value => "admin"},
  :created_at => {:xtype => 'datetime', :disabled => true, :value => "2010-10-10 10:10"}
}
