Create has_many relationships from form

So if I have a two models like this:

#parent.rb
class Parent < ApplicationRecord
    has_many :children
end

#children.rb
class Child < ApplicationRecord
    belongs_to :parent
end

How would you create a form that allows you to create multiple children in the form that creates the parent?

Cocoon[0] solves this problem quite nicely, and has a great example app.

Rolling on the back-end, throw accepts_nested_attributes_for :children on your Parent model, do some fields_for (or simple_fields_for) stuff in your form, and make sure you can assign the attributes by adding children_attributes: [:name, :age] to your parent_params.
