You copied initialize_dup example to your model, you should add that method
only if you have some has_many, has_one or has_and_belongs_to_many
associations which needs to be copied. In the example:
class Bill < ActiveRecord::Base
belongs_to :customer
has_many :items
def initialize_dup(other)
super
self.items = other.items.map(&:dup)
end
end
Bill model has 2 associations, customer is copied to cloned record, but
initialize_dup with self.items = other.items.map(&:dup) line is needed to
clone bill with items.
Another issue is you are getting a JS post request, although you changed link
to use get and page request, I have same config here and it works.
