lesson 1

1.1 创建100个Django用户

def create_user(name):
    from django.contrib.auth.models import User
    for i in range(100):
        username = '{}_{}'.format()
        User.objects.create_user(username,username+'@qq.com','123456')

create_user('ray')

1.2 用视图函数获取用户列表，并分页

1.2.1视图代码

from django.contrib.auth.models import User
from django.http import JsonResponse
def user_list(request):
    if request.method == 'GET':
        # 获取所有数据
        user = User.objects.all()
        # 获取每页分的条数
        per_num = int(request.GET['per_num'])
        # 获取第几页
        page = int(request.GET['page'])
        # 转化成list
        test_list = list(user.values('id','username','email'))
        # 分页
        end_page = per_num*page
        start_page = end_page-per_num
        per_result = test_list[start_page:end_page]
        return JsonResponse(per_result,safe=False)

1.22 URL代码

dashboard.urls

from django.conf.urls import url,include
from .views import user_list
urlpatterns = [
    url(r'^user_list',user_list , name='user_list')
]

1.2.3 访问方式

例如：访问第1页，每页4条数据

http://127.0.0.1:8000/dashboard/user_list?page=1&per_num=4
