Add a form helper method

Question

Ive made a nice editor in jQuery and i want to add it as a form helper method.

how would i go about making a new form helper method?

ideally id like to be able to call:

f.nice_editor :field

Answer 1

Part of the question is: where do you put the nice_editor code? I don't think it is a good idea to directly edit class ActionView::Helpers::FormBuilder in your installation. Instead, put your code in one of the files in app/helpers. There are several ways to add extension methods to FormBuilder.

For instance, suppose you have a helper file items_helper.rb:

module ItemsHelper
    # this is one way to define new instance methods
    ActionView::Helpers::FormBuilder.class_eval do
        def nice_editor(conf,*opts)
            ...
        end
    end
end

Also, see this good discussion, which shows how to use self.included() to extend FormBuilder.
