Django的查询所有，根据用户名查询，增加用户操作

1.路由

from meiduo_admin.user.user_views import UsersView

urlpatterns = [

    # 用户操作路由
    path('users/', UsersView.as_view()),
]

2. 序列化器

from rest_framework import serializers

from meiduo_admin.models import User


class UsersSerialize(serializers.ModelSerializer):
    class Meta:
        model = User
        fields = ['id', 'username', 'mobile', 'email', 'password']

        # 1,给password增加额外的约束选项，不进行返回
        extra_kwargs = {
            "password": {
                'write_only': True
            }
        }

    # 1,重写create方法，密码加密
    def create(self, validated_data):
        return User.objects.create_user(**validated_data)

3. 视图

from rest_framework.generics import ListAPIView, CreateAPIView

from meiduo_admin import models
from meiduo_admin.user.user_serializers import UsersSerialize

from meiduo_admin.utils.myPagination import MyPageNumberPagination


class UsersView(ListAPIView, CreateAPIView):
    pagination_class = MyPageNumberPagination
    serializer_class = UsersSerialize

    # queryset = models.User.objects.filter(is_staff=False).all().order_by('-date_joined')

    # 1. 为了获取前端查询条件keyword重写get_queryset方法
    def get_queryset(self):
        # 2. 获取前端传入的参数keyword，名称由前端指定
        keyword = self.request.query_params.get('keyword')
        if keyword:
            return models.User.objects.filter(is_staff=False, username__contains=keyword).all().order_by('-date_joined')
        return models.User.objects.filter(is_staff=False).all().order_by('-date_joined')
