在模型中访问设备 current_user [英] accessing devise current_user within model

问题描述

我正在尝试访问模型中的 current_user，目的是使用 find_or_create_by 动态创建元素.

hi i am trying to access current_user within a model for the purpose of creating an element on the fly with find_or_create_by.

以下是我模型中的方法

def opponent_name=(name)
self.opponent = Opponent.find_or_create_by_name_and_team_id(name,current_user.team_id) if name.present?
end

但我得到的错误是

NameError in EventsController#create

undefined local variable or method `current_user' for #<Event:0x007fb575e92000>

推荐答案

在模型文件中访问 c​​urrent_user:

Access current_user in Model File:

# code in Applcation Controller:
class ApplicationController < ActionController::Base
  before_filter :global_user

  def global_user
    Comment.user = current_user
  end
end

#Code in your Model File :
class Comment < ActiveRecord::Base
  cattr_accessor :user  # it's accessible outside Comment
  attr_accessible :commenter 

  def assign_user
    self.commenter = self.user.name
  end
end

请原谅我，如果它违反了任何 MVC 架构规则.

Pardon me, if It violates any MVC Architecture Rules.
