Rails：定义控制器的方法

Question

Newbie question! I'm trying to get my head around how I can set up specific Active Record searches which I then call from my controllers. Why is this throwing an undefined method error?

method defined in the Model:

class Event < ActiveRecord::Base

    attr_accessible :category, :date_end, :date_start, :description, :time_start, :title, :venue, :image


    def next_seven_days
        t = Time.now
        Event.where("date_end BETWEEN ? AND ?", t, t+7.days).order("date_end ASC")
    end
end

Controller

def index
    @events = Event.next_seven_days     
end

Answer 1

because you haven't defined the method you're calling as a class method

try

 def self.next_seven_days

in the activerecord class instead of what you have
