rails 4 cancancan多态

Question

无论出于什么原因，用于跟随/追随者的代码不再起作用，我怀疑我需要一个取消规则，但我不确定。希望有人能看到我的错误。

配置文件模型

class Profile < ActiveRecord::Base
  ...
  has_many :follower_relationships, foreign_key: :following_id, class_name: 'Follow', dependent: :destroy
  has_many :followers, through: :follower_relationships, source: :follower
  has_many :following_relationships, foreign_key: :follower_id, class_name: 'Follow', dependent: :destroy
  has_many :following, through: :following_relationships, source: :following
  ...
end

遵循模型

class Follow < ActiveRecord::Base
  ...
  belongs_to :follower, foreign_key: 'follower_id', class_name: 'Profile'
  belongs_to :following, foreign_key: 'following_id', class_name: 'Profile'
  ...
end

配置文件控制器

class ProfilesController < ApplicationController
  ...
  load_and_authorize_resource
  ...
  def follow
    if current_user.profile.follow(@profile.id)
      SystemMailer.following_email(@profile.user, current_user).deliver_later
      redirect_to request.referrer
    end
  end

  def unfollow
    redirect_to request.referrer if current_user.profile.unfollow(@profile.id)
  end 

当前ability.rb

class Ability
  include CanCan::Ability
  ...
  can :edit, Profile, user_id: user.id
  can :read, Profile
  can :update, Profile, user_id: user.id
  can :show, Profile
  can :manage, Profile, id: user.profile.id

我已经尝试了各种can能力，但我觉得我只是在胡乱操作。如果上面的代码行没有错误，有人能指出我应该实施的can规则吗？

谢谢!

Answer 1

我弄清楚了，它实际上不是因为模型组织而被阻止，这些操作在能力类中是不被允许的。

添加：

can :follow, Profile
can :unfollow, Profile

解决了问题。很抱歉浪费大家的时间。
