Question

so i’ve got one pretty simple method in a model here:

  def log
    self.statistics.build()
    self.save
    return
  end

now i wanted to exclude this method into a module to use it in different models.

module Statistic
  def log
    self.statistics.build()
    self.save
    return
  end
end

i added the file to the autoload paths and included it into my model (the inclusion works fine).

class Foo < ActiveRecord::Base
  include Statistic
end

trying to call the .log method results in an error:
undefined methodnew’ for Statistic:Modulethe raised line number is theself.statistics.build()` line.

any ideas why this is not working?

thanks for all hints! please leave a comment if something is unclear.

Answer 1

I think this is a naming clash.

It seems you have a has_many :statistics, by default this will look for a class called Statistic.

But this is the same name as the module you have created.

I suggest renaming your module to StatisticsExtensions or something of that sort.
