Call helper method from model

Question

For my Predictions model I created a method in predictions_helper.rb like this:

module PredictionsHelper

  def time_in_date(time, date)
    time.between(date..date+1.day)
  end
end

However, when I call it like this:

time_in_date(le.time, date)

I get the following error:

NoMethodError:
       undefined method `time_in_date' for PredictionsHelper:Module

Answer 1

It seems like the easiest thing to do would be to include your module in your Predictions class

class Prediction < ActiveRecord::Base
  include PredictionsHelper
end

That will give you access to time_in_date

Answer 2

The predictions_helper is within scope of the Predictions model, however, since you've put it inside of a module, you'll need to include that module.

So:

include PredictionsHelper
# code...

or

PredictionsHelper::time_in_date(le.time, date)
