Helper方法没有暴露给控制器Rails

Question

Here's the code:

class SyncController < ApplicationController
  def get_sync
    @passed_ids = params[:ids].split(',')
    @users = @passed_ids.collect{|id| User.find(id)}

    #add the current user to the list
    @users << current_user
    @recommendations = get_recommendations(@users)
  end
end

module SyncHelper
  def get_recommendations(users)
    users
  end
end

I'm getting a can't find get_recommendations method error...

Answer 1

Your SyncHelper module needs to be included into your SyncController class. You can either add the line

include SyncHelper

in your class definition, or, if SyncHelper lives in the expected app/helpers file, you can use the rails helper method.
