我是Ruby on Rails的新手，迄今为止，我创建了用户登录，注册，注销，但我想创建一个管理员用户，但我不知道这个怎么做。如何使用Ruby on Rails创建管理员用户
route.rb是：
Rails.application.routes.draw do
get 'courses/index'
get 'courses/new'
get 'courses/edit'
get 'courses/show'
get 'course/index'
get 'course/new'
get 'course/edit'
get 'course/show'
get 'sessions/signin'
get 'sessions/main'
get 'sessions/profile'
get 'sessions/setting'
get 'users/new'
get 'home/index'
resources :users, path_names: {new: "signup"} do
collection do
get "main", action: :new
end
end
resources :sessions, path_names: {new: "signin", destroy: "signout"} do
collection do
get :signin
get :main
get :profile
get :setting
end
end
resources :home, only: [], path: "" do
get :about
end
root 'home#index'
resources :courses, only: [:index, :new, :edit, :show]
#resources :course, only: [:index, :new, :edit, :show]
resources :courses
resources :course_groups
patch 'course_groups/:id/add_course', to: 'course_groups#add_course', as: 'course_group_add_course'
delete 'course_groups/:id/delete_course', to: 'course_groups#destory_course', as: 'course_group_destory_course'
resources :rules
patch 'rules/:id/add_group', to: 'rules#add_group', as: 'rule_add_course_group'
delete 'rules/:id/delete_group', to: 'rules#destroy_group', as: 'rule_destroy_course_group'
resources :requirements
patch 'requirements/:id/add_rule', to: 'requirements#add_rule', as: 'requirement_add_rules'
delete 'requirements/:id/delete_rule', to: 'requirements#destroy_rule', as: 'requirement_destroy_rules'
#resources :plans
resources :users do
resources :plans
end
patch 'users/:user_id/plans/:id/add_course', to: 'plans#add_course', as: 'plan_add_course'
delete 'users/:user_id/plans/:id/delete_course', to: 'plans#destory_course', as: 'plan_destory_course'
match '/about', to: 'home#about', via: 'get'
match '/signup', to: 'users#new', via: 'get'
match ':controller(/:action(/:id))(.:format)', via: 'get'
match '/signin', to: 'sessions#new', via: 'get'
match '/signout', to: 'sessions#destroy', via: 'delete'
match '/main', to: 'users#new', via: 'get'
#match '/profile', to: 'sessions#profile', via: 'get'
match '/setting', to: 'sessions#setting', via: 'get'
match '/editname', to: 'users#edit', via: 'get'
match '/show', to: 'users#show', via: 'get'
match '/profile', to: 'users#profile', via: 'get'
#match '/info', to: 'users#info', via: 'get'
#match '/changepass', to: 'users#edit', via: 'get'
end
和我users_controller.rb是：
class UsersController < ApplicationController
before_filter :check_if_signned_in, only: [:show, :edit, :update, :delete]
before_filter :signed_in_user, only: [:edit, :update]
before_filter :skip_password_attribute, only: :update
def new
@user = User.new
end
def create
@user = User.new(user_params)
if @user.save
redirect_to @user, notice: 'User was sucessfully created!'
else
render action: "new"
end
end
#if current user exits, then it can get back to the main page of user
def show
if current_user.nil?
@user = User.find(params[:id])
else
@user = User.find(current_user)
end
end
def edit
#@user = User.find(params[:id])
#@user = User.find(current_user)
@user = current_user
@user.save
@title = "Edit profile"
end
def update
@user = User.find(params[:id])
#@user = User.find(current_user)
#if @user.update_attributes(user_params)
if @user.update_attributes(user_params)
flash[:success] = "Profile updated."
#sign_in @user_params
redirect_to @user
else
@title = "Edit profile"
render 'edit'
end
end
private
def user_params
params.require(:user).permit(:name, :email, :password, :password_confirmation)
end
def signed_in_user
redirect_to signin_path, notice: "Please sign in." unless signed_in?
end
def edit_user
params.require(:user).permit(:name)
end
def skip_password_attribute
if params[:password].blank? && params[:password_confirmation].blank?
params.except!(:password, :password_confirmation)
end
end
end
的application_controller.rb是：
class ApplicationController < ActionController::Base
# Prevent CSRF attacks by raising an exception.
# For APIs, you may want to use :null_session instead.
#protect_from_forgery with: :exception
protect_from_forgery
#before_filter :session_expire
#before_filter :update_active_time
include SessionsHelper
def check_if_signned_in
deny_access unless signed_in?
end
#def update_active_time
# session[:expires_at] = default_expire
#end
def is_owner
current_user.id == params[:id]
end
#private
# def get_session_time_left
# expire_time = session[:expires_at] #|| default_expire
# a = expire_time
# b = Time.now
# @session_time_left = (a - b).do_i
#@session_time_left = (expire_time - Time.now).do_i
# end
end
任何人都可以教我如何创建一个管理员用户吗？当管理员用户登录时，它将转到另一个不同的页面。 提前谢谢！
