第9章 dashboard 后端的搭建与开发

9-5 dashboard搭建与管理员模块开发（5） 

1.在项目 vedio 下目录 app/dashboard/views，修改文件 auth.py

# coding:utf-8

from django.views.generic import View
from django.shortcuts import redirect, reverse
from django.contrib.auth import login, authenticate
from django.contrib.auth.models import User
from app.libs.base_render import render_to_response

class Login(View):
    TEMPLATE = 'dashboard/auth/login.html'

    def get(self, request):
        data = {'error': ''}
        return render_to_response(request, self.TEMPLATE, data=data)

    def post(self, request):
        username = request.POST.get('username')
        password = request.POST.get('password')
        print(username, password)

        data = {}
        exists = User.objects.filter(username=username).exists()
        data['error'] = '没有该用户'
        if not exists:
            return render_to_response(request, self.TEMPLATE, data=data)

        user = authenticate(username=username, password=password)
        if not user:
            data['error'] = '密码错误'
            return render_to_response(request, self.TEMPLATE, data=data)
        if not user.is_superuser:
            data['error'] = '你无权登录'
            return render_to_response(request, self.TEMPLATE, data=data)
        login(request, user)
        return redirect(reverse('dashboard_index'))

2.在项目 vedio 下目录 app/dashboard，修改文件 urls.py　

# coding:utf-8

from django.urls import path
from .views.base import Index
from .views.auth import Login

urlpatterns = [
    path('', Index.as_view(), name='dashboard_index'),
    path('login', Login.as_view(), name='dashboard_login'),
]

3.在项目 vedio 下目录 templates/dashboard/auth，修改文件 login.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>登录</title>
    <link rel="stylesheet" href="/static/dashboard/css/bootstrap.min.css" />
    <link rel="stylesheet" href="/static/dashboard/css/login.css" />
</head>
<body>
<form class="form-horizontal edit-area" action="/dashboard/login" method="post">
    ${csrf_token}
    <div class="form-group">
        <div class="col-sm-10">
            <input type="text" name="username" class="form-control" placeholder="用户名">
        </div>
    </div>
    <div class="form-group">
        <div class="col-sm-10">
            <input type="password" name="password" class="form-control" placeholder="密码">
        </div>
    </div>
    <div class="form-group">
        <div class="col-sm-offset-2 col-sm-10">
            <button type="submit" class="btn btn-default">登录</button>${error}
        </div>
    </div>
</form>
</body>
</html>

4.在项目 vedio 下目录 app/dashboard/views，修改文件 auth.py

# coding:utf-8

from django.views.generic import View
from django.shortcuts import redirect, reverse
from django.contrib.auth import login, authenticate
from django.contrib.auth.models import User
from app.libs.base_render import render_to_response

class Login(View):
    TEMPLATE = 'dashboard/auth/login.html'

    def get(self, request):
        if request.user.is_authenticated:
            return redirect(reverse('dashboard_index'))
        data = {'error': ''}
        return render_to_response(request, self.TEMPLATE, data=data)

    def post(self, request):
        username = request.POST.get('username')
        password = request.POST.get('password')
        print(username, password)

        data = {}
        exists = User.objects.filter(username=username).exists()
        data['error'] = '没有该用户'
        if not exists:
            return render_to_response(request, self.TEMPLATE, data=data)

        user = authenticate(username=username, password=password)
        if not user:
            data['error'] = '密码错误'
            return render_to_response(request, self.TEMPLATE, data=data)
        if not user.is_superuser:
            data['error'] = '你无权登录'
            return render_to_response(request, self.TEMPLATE, data=data)
        login(request, user)
        return redirect(reverse('dashboard_index'))

5.测试

6.在项目 vedio 下目录 app/dashboard/views，修改文件 auth.py，添加类 AdminManger

# coding:utf-8

from django.views.generic import View
from django.shortcuts import redirect, reverse
from django.contrib.auth import login, authenticate
from django.contrib.auth.models import User
from app.libs.base_render import render_to_response

class Login(View):
    TEMPLATE = 'dashboard/auth/login.html'

    def get(self, request):
        if request.user.is_authenticated:
            return redirect(reverse('dashboard_index'))
        data = {'error': ''}
        return render_to_response(request, self.TEMPLATE, data=data)

    def post(self, request):
        username = request.POST.get('username')
        password = request.POST.get('password')
        print(username, password)

        data = {}
        exists = User.objects.filter(username=username).exists()
        data['error'] = '没有该用户'
        if not exists:
            return render_to_response(request, self.TEMPLATE, data=data)

        user = authenticate(username=username, password=password)
        if not user:
            data['error'] = '密码错误'
            return render_to_response(request, self.TEMPLATE, data=data)
        if not user.is_superuser:
            data['error'] = '你无权登录'
            return render_to_response(request, self.TEMPLATE, data=data)
        login(request, user)
        return redirect(reverse('dashboard_index'))

class AdminManger(View):
    TEMPLATE = 'dashboard/auth/admin.html'
    def get(self, request):
        return render_to_response(request, self.TEMPLATE)

7.在项目 vedio 下目录 app/dashboard，修改文件 urls.py　　

# coding:utf-8

from django.urls import path
from .views.base import Index
from .views.auth import Login, AdminManger
