path('get2/', views.HelloApiView.as_view())

models

复制代码

class Student(models.Model):
    name = models.CharField(max_length=100,verbose_name='姓名')
    age = models.IntegerField(verbose_name='年龄')
    sex = models.BooleanField(default=1,verbose_name='性别')
    class_null = models.CharField(max_length=5,verbose_name='班级编号')
    class Meta:
        db_table = 'tb_student'

python manage.py makemigrations myapp

生成表

python manage.py migrate

数据库

复制代码

INSTALLED_APPS 中添加app名称

执行之后的结果

复制代码

class Book(models.Model):
    title = models.CharField(max_length=32,verbose_name='书籍')
    price = models.IntegerField(verbose_name='价格')
    pub_date = models.DateField(verbose_name='出版日期')
    bread = models.IntegerField(verbose_name='阅读量')
    bcomment = models.IntegerField(verbose_name='评论量')
    publish = models.ForeignKey('Publish',on_delete=models.CASCADE,verbose_name='出版社')
    def __str__(self):
        return self.title
class Publish(models.Model):
    name = models.CharField(max_length=32,verbose_name='出版社名称')
    email = models.EmailField(verbose_name='出版社邮箱')
    def __str__(self):
        return self.name
class Author(models.Model):
    name = models.CharField(max_length=32,verbose_name='作者')
    age = models.IntegerField(verbose_name='年龄')
    def __str__(self):
        return self.name

三个表

复制代码

serializers 里面包含哪些字段

复制代码

from rest_framework import serializers
class StudentSerializer(serializers.Serializer):
    name = serializers.CharField()

序列化

复制代码

return  Response(serializer.data)

返回的值就会是

复制代码

students = Student.objects.all()

复制代码

names = serializers.CharField(source='name')

names的赋值

复制代码

re_path('get3/(\d+)/', views.Details.as_view())

复制代码

    def get(self,request,id=None):
        students = Student.objects.get(pk=id)

        serializer = StudentSerializer(instance=students, many=False)

反序列化
