Rails 4 rolify 和活动管理员无法添加/更新角色

Question

您好，我有两个表 Active admin 和 user。我希望 activeadmin 能够创建用户或/并更改用户的角色。

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 日志说未经许可的参数角色_id

下面是我最后一次更改的管理员/用户

我正在使用 Devise、CanCan 和 Rolify。 当我添加或更新角色时，会创建一个名为 # 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 是未经许可的参数。 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role_ids: [] 而不是:role_ids

permit_params :email, :password, role_ids: []

或

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