Module: Algorithms::Prompt

Test if prompt is bad. Prompt is bad if it does not have 2 items or if any of its items are nil.

    # File lib/algorithms/prompt.rb, line 35
35:   def bad_prompt?(prompt)
36:     return (prompt.items.length != 2 || prompt.items.any?(&:nil?))
37:   end

41:       :joins => "INNER JOIN items_questions ON (items_questions.question_id=#{question_id} AND items_questions.item_id=items.id)",
42:       :conditions => { :active => true },

44:   end

create_prompts(question_id, voter_id, count, algo)

Generate count number of prompts based on question and voter. Choose generation algorithm based on prime.

Return

An array of prompts

Parameters

question_id<int>:	Prompts for this question ID.
voter_id<int>:	Prompts for this voter ID.
count<int>:	This number of prompts.
prompt<bool>:	If true primed prompts are generated, otherwise random

prompts are generated.
