ruby-on-rails - 在管理 Gem Rails 中设置管理员

Question

我已经关注了 guide关于如何在 Rails 中为我的应用程序安装管理 gem，但我想添加的是仅由我设置管理员的功能。我关注了Gtihub说明，但我坚持如何将我的电子邮件或任何其他用户的电子邮件设置为管理员。这是我到目前为止添加的内容:

controller/admin/application_controller.rb

# All Administrate controllers inherit from this `Admin::ApplicationController`,
# making it the ideal place to put authentication logic or other
# before_filters.
#
# If you want to add pagination or other controller-level concerns,
# you're free to overwrite the RESTful controller actions.
class Admin::ApplicationController < Administrate::ApplicationController

  before_action :authenticate_user!
  before_action :authenticate_admin

  def authenticate_admin
    redirect_to '/', alert: 'Not authorized.' unless current_user && access_whitelist
  end

  private
    def access_whitelist
      current_user.try(:admin?) || current_user.try(:door_super?)
    end

  # Override this value to specify the number of elements to display at a time
  # on index pages. Defaults to 20.
  # def records_per_page
  #   params[:per_page] || 20
  # end
end

dashboards/user_dashboard.rb

require "administrate/base_dashboard"

class UserDashboard < Administrate::BaseDashboard
  # ATTRIBUTE_TYPES
  # a hash that describes the type of each of the model's fields.
  #
  # Each different type represents an Administrate::Field object,
  # which determines how the attribute is displayed
  # on pages throughout the dashboard.
  ATTRIBUTE_TYPES = {
    posts: Field::HasMany,
    reviews: Field::HasMany,
    id: Field::Number,
    email: Field::String,
    encrypted_password: Field::String,
    reset_password_token: Field::String,
    reset_password_sent_at: Field::DateTime,
    remember_created_at: Field::DateTime,
    sign_in_count: Field::Number,
    current_sign_in_at: Field::DateTime,
    last_sign_in_at: Field::DateTime,
    current_sign_in_ip: Field::String,
    last_sign_in_ip: Field::String,
    created_at: Field::DateTime,
    updated_at: Field::DateTime,
    name: Field::String,
    password: PasswordField,
    password_confirmation: PasswordField

  }

  # COLLECTION_ATTRIBUTES
  # an array of attributes that will be displayed on the model's index page.
  #
  # By default, it's limited to four items to reduce clutter on index pages.
  # Feel free to add, remove, or rearrange items.
  COLLECTION_ATTRIBUTES = [
    :posts,
    :reviews,
    :id,
    :email,
  ]

  # SHOW_PAGE_ATTRIBUTES
  # an array of attributes that will be displayed on the model's show page.
  SHOW_PAGE_ATTRIBUTES = ATTRIBUTE_TYPES.keys

  # FORM_ATTRIBUTES
  # an array of attributes that will be displayed
  # on the model's form (`new` and `edit`) pages.
  FORM_ATTRIBUTES = [
    :posts,
    :reviews,
    :email,
    :password,
    :password_confirmation,
    # :encrypted_password,
    # :reset_password_token,
    # :reset_password_sent_at,
    # :remember_created_at,
    # :sign_in_count,
    # :current_sign_in_at,
    # :last_sign_in_at,
    :current_sign_in_ip,
    :last_sign_in_ip,
    :name,
  ]

  # Overwrite this method to customize how users are displayed
  # across all pages of the admin dashboard.
  #
  # def display_resource(user)
  #   "User ##{user.id}"
  # end
end

这就是我管理访问的方式

# All Administrate controllers inherit from this `Admin::ApplicationController`,
# making it the ideal place to put authentication logic or other
# before_filters.
#
# If you want to add pagination or other controller-level concerns,
# you're free to overwrite the RESTful controller actions.
module Admin
  class ApplicationController < Administrate::ApplicationController
    before_filter :authenticate_admin

    def authenticate_admin
      redirect_to root_url unless current_user.try(:admin)
    end

    # Override this value to specify the number of elements to display at a time
    # on index pages. Defaults to 20.
    # def records_per_page
    #   params[:per_page] || 20
    # end
  end
end

所以它基本上检查 current_user 方法的 bool 字段。如果您没有，请为您的用户模型创建它，或者使用授权系统提供的。
