I'm trying to write a gem that extends the methods available to ActiveRecord models. At this point it's super simple, and only consists of 3 files, per following the instructions listed on this question: Rails extending ActiveRecord::Base and using Railties to self-initilize.
my_gem.rb
require 'my_gem/railtie' if defined? ::Rails::Railtie
my_gem/railtie.rb
require 'my_gem/extensions'
module MyGem
class Railtie < ::Rails::Railtie
initializer "my_gem.extensions" do
ActiveSupport.on_load(:active_record) do
ActiveRecord::Base.send :include, Extensions
end
end
end
end
my_gem/extensions.rb
module MyGem
module Extensions
extend ActiveSupport::Concern
module ClassMethods
def in_the_past_x_days x = 14
where("#{self.table_name}.created_at > ?", x.days.ago)
.group("DATE(#{self.table_name}.created_at)")
end
end
end
end
This results in a "NoMethodError", however, whenever I try to call in_the_past_x_days
. Am I missing something obvious?
Update
Turns out it was something obvious, see answer for details.
