Question

您好我有两个表Active管理员和用户。我希望activeadmin能够创建用户或/和更改用户的角色。

我可以创建用户，但无法在创建和更新时向用户添加角色您可以在底部看到错误。 Rails日志说未经许可的param roles_id

下面是我的管理员/用户，上次更改了

我正在使用Devise，CanCan＆amp; Rolify。 当我添加或更新角色时，会创建名为＃的角色记录它被添加到角色而不是选定的选项。我看到roles_id是不允许的params。但我已将其添加到允许的参数中。即使在控制器中添加允许的参数

，它也不起作用

ActiveAdmin.register User do
  permit_params :email , :role_ids ,:password

  form do |f|
    f.inputs "Users" do
      f.input :email
      f.input :password
      f.input :roles, as: :select, multiple: false, collection: Role.all

    end
    f.actions
  end 

  show do
    binding.pry
    attributes_table do
      row :email
      row :roles do | user |
        user.roles.first.name unless user.roles.blank?
      end
    end
  end

  index do
    column :email
    column :roles do | user |
        user.roles.first.name unless user.roles.blank?
    end
    actions
  end
  controller do
    def create
      @user = User.new(user_params)
      add_roles(@user)
      create!
    end

    def update
      add_roles(resource)
      update!(user_params)
    end

    private
      def add_roles(resource)
        resource.roles = []
        params[:user][:role_ids].each { 
          |r| resource.add_role(Role.find(r)) unless r.blank? 
        }
      end
      def user_params
        params.require(:user).permit(:email, :password)
      end
    end
end

Answer 1

尝试使用role_ids: []代替:role_ids

permit_params :email, :password, role_ids: []

或

permit_params :email, :password, :role_ids => []

Rails 4 rolify和活动管理员无法添加/更新角色
