# Add this snippet into your ApplicationHelper to make it available to all views | |
# This method enables a simple but clean way to handle nested forms when a :has_many relationship | |
# along with the :accepts_nested_attributes_for methods are invoked in the model. | |
# Instead of making a method for each of the first arguments of the form_for() method, you can now just | |
# invoke the "nestable()" method and pass in the object in the first argument, followed by any associated/nested models. | |
# See the method and example comments below | |
module ApplicationHelper | |
# Call on first argument of the "form_for" method |
