You need to be passing the form builder through to the partial  
(via :locals for example).  
Since you haven’t, ruby assumes that form refers to the method form,  
which does indeed take at least one argument.

Hi,  
I don’t quite understand the previous posting. Can anyone please  
elaborate.

You’re trying to use your formbuilder ‘form’ in your partial, but  
there is no local variable called form in that partial and so ruby  
assumes you’re calling the form function, which requires at least one  
parameter (hence the error). You need to pass the form to the partial  
using locals, ie render :partial =\> ‘some\_partial’, :locals =\> {:form  
=\> foo}  
will make a local variable in that partial called form and whose value  
is foo.

Or, name the partial ‘\_form.html.erb’ and render it as an object:

\<%= render :partial =\> ‘form’, :object =\> form %\>
