models

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

INSTALLED_APPS 中添加app名称

执行之后的结果

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

serializers 里面包含哪些字段

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

序列化

return  Response(serializer.data)

返回的值就会是

students = Student.objects.all()

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

names的赋值

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

    def get(self,request,id=None):students = Student.objects.get(pk=id)serializer = StudentSerializer(instance=students, many=False)

反序列化
