Use form_for without the enclosing form tag

In rare cases you might need something like form_for (for using form builder methods on the resulting block element) but without the surrounding form. One such case would be updating some of a form's fields via XHR.

You can simply use Rails' fields_for to do things like this in your views (HAML here):
- fields_for @user do |form|
= form.label :email, 'E-Mail'
= form.text_field :email

You will only receive the form content you gave, no hidden inputs including the authenticity token etc.

By refactoring problematic code and creating automated tests, makandra can vastly improve the maintainability of your Rails application.
