33	33	# </form>
34	34	#
	35	# If you are using a partial for your form fields, you can use this shortcut:
	36	#
	37	# <% form_for :person, @person, :url => { :action => "create" } do \|f\| %>
	38	# <%= render :partial => f %>
	39	# <%= submit_tag 'Create' %>
	40	# <% end %>
	41	#
	42	# This example will render the <tt>people/_form</tt> partial, setting a local variable called <tt>form</tt> which references the yielded FormBuilder.
	43	#
35	44	# The <tt>params</tt> object created when this form is submitted would look like:
36	45	#
…	…
153	162	# <%= check_box_tag "person[admin]", @person.company.admin? %>
154	163	# <% end %>
	164	#
	165	# In this case, if you use this:
	166	#
	167	# <%= render :partial => f %>
	168	#
	169	# The rendered template is <tt>people/_labelling_form</tt> and the local variable referencing the form builder is called <tt>labelling_form</tt>.
155	170	#
156	171	# In many cases you will want to wrap the above in another helper, so you could do something like the following:
