01 Stark总结

1.1 编写类starkConfig；

1.2 注册类似于admin.site.register();

1.3 设计URL；

02 ORM总结

2.1 基于双下划线的查询;

models.py

from django.db import models

# Create your models here.

class Author(models.Model):
    nid = models.AutoField(primary_key=True)
    name = models.CharField(max_length=32)
    age = models.IntegerField()
    # 与AuthorDetail建立一对一的关系;
    authorDetail = models.OneToOneField(to="AuthorDetail", on_delete=models.CASCADE)

    def __str__(self):
        return self.name

class AuthorDetail(models.Model):
    nid = models.AutoField(primary_key=True)
    birthday = models.DateField()
    telephone = models.BigIntegerField()
    addr = models.CharField(max_length=64)

    def __str__(self):
        return self.telephone

class Publish(models.Model):
    nid = models.AutoField(primary_key=True)
    name = models.CharField(max_length=32)
    city = models.CharField(max_length=32)
    email = models.EmailField()

    def __str__(self):
        return self.name

class Book(models.Model):
    nid = models.AutoField(primary_key=True)
    title = models.CharField(max_length=32)
    publishDate = models.DateField()
    price = models.DecimalField(max_digits=5, decimal_places=2)
    # 与Publish表建立一对多的关系，外键字段在多的一方;
    publish = models.ForeignKey(to="Publish", to_field="nid", on_delete=models.CASCADE)
    # 与Author表建立多对多的关系，ManyToManyField可以建立在两个模型中的任意一个，自动创建第三张表;
    authors = models.ManyToManyField(to="Author")

    def __str__(self):
        return self.title

views.py

from django.shortcuts import render, HttpResponse

# Create your views here.
from .models import *

def index(request):
    # ret1 = Publish.objects.filter(name="沙河出版社").values("book__title", "book__price")
    # print("ret1", ret1)
    # print("query", ret1.query)

    ret2 = Book.objects.filter(publish__name="沙河出版社").values("title", "price")
    print(ret2)
    print(ret2.query)
    return HttpResponse("ok")
