<% fieldset 'User Registration' do %>
// fields
<% end %>
# File lib/form_assistant/view_helpers.rb, line 35 def fieldset(legend, &block) locals = { :legend => legend, :fields => capture(&block) } partial = render(:partial => "#{RPH::FormAssistant::FormBuilder.template_root}/fieldset.html.erb", :locals => locals) # render the fields binding_required ? concat(partial, block.binding) : concat(partial) end

easy way to make use of FormAssistant::FormBuilder
<% form_assistant_for
@project do |form| %>
// fancy form stuff
<% end %>
# File lib/form_assistant/view_helpers.rb, line 25 def form_assistant_for(record_or_name_or_array, *args, &proc) form_for_with_builder(record_or_name_or_array, RPH::FormAssistant::FormBuilder, *args, &proc) end
Private Instance Methods
binding_required()

determines if binding is needed for concat() (Rails 2.2.0 and greater no longer requires the binding)
# File lib/form_assistant/view_helpers.rb, line 15 def binding_required RPH::FormAssistant::Rules.binding_required? end
form_for_with_builder(record_or_name_or_array, builder, *args, &proc)
click to toggle source
used to ensure that the desired builder gets set before calling form_for()
# File lib/form_assistant/view_helpers.rb, line 7 def form_for_with_builder(record_or_name_or_array, builder, *args, &proc) options = args.extract_options! # hand control over to the original #form_for() form_for(record_or_name_or_array, *(args << options.merge!(:builder => builder)), &proc) end
