1，添加模型
Test/app8/models.py
from django.db import models
class User(models.Model):
username = models.CharField(max_length=50, unique=True)
email = models.EmailField(unique=True)
password = models.CharField(max_length=128) # 使用哈希存储密码
first_name = models.CharField(max_length=60)
last_name = models.CharField(max_length=50)
# 添加其他字段，例如：
# age = models.IntegerField()
# bio = models.TextField()
# ...
class Meta:
db_table = 'users2'
def __str__(self):
return self.username
class Person(models.Model):
name = models.CharField(max_length=100)
age = models.IntegerField()
def __str__(self):
return self.name
class Passport(models.Model):
person = models.OneToOneField(Person, on_delete=models.CASCADE)
passport_number = models.CharField(max_length=20)
issue_date = models.DateField()
def __str__(self):
return f"{self.passport_number} - {self.person.name}"
2，执行迁移命令
python manage.py makemigrations app8
python manage.py migrate app8使用迁移命令会生成Person和Passport两个张模型表，Passport表中生成一个外键，命名为person_id
3，创建视图函数
Test/app8/views.py
from django.shortcuts import render
from .models import User
def create_user(request):
if request.method == 'POST':
username = request.POST.get('username')
email = request.POST.get('email')
# ... 获取其他字段的值
# 创建用户实例
user = User(
username=username,
email=email,
# ... 填充其他字段
)
user.save() # 保存到数据库
# ... 处理成功或失败的逻辑
return render(request, '8/1.html')
from django.shortcuts import render, get_object_or_404
from django.http import HttpResponse
from app8.models import Person, Passport
def delete_person(request, person_id):
person_to_delete = get_object_or_404(Person, id=person_id)
person_to_delete.delete()
return HttpResponse("Person and associated Passport have been deleted.")
from django.shortcuts import render
from django.http import HttpResponse
from .models import Person, Passport
import datetime
def add_data(request):
if request.method == 'POST':
name = request.POST.get('name')
age = request.POST.get('age')
passport_number = request.POST.get('passport_number')
issue_date = request.POST.get('issue_date')
person = Person(name=name, age=age)
person.save()
passport = Passport(person=person, passport_number=passport_number, issue_date=datetime.datetime.strptime(issue_date, '%Y-%m-%d').date())
passport.save()
return HttpResponse("数据已成功保存！")
else:
return render(request, '8\insert_data.html')
4，添加html代码
Test/templates/8/insert_data.html
<!DOCTYPE html>
<html>
<head>
<title>插入数据</title>
</head>
<body>
<form method="post">
{% csrf_token %}
<label for="name">姓名:</label><br>
<input type="text" id="name" name="name"><br>
<label for="age">年龄:</label><br>
<input type="text" id="age" name="age"><br>
<label for="passport_number">护照号码:</label><br>
<input type="text" id="passport_number" name="passport_number"><br>
<label for="issue_date">发行日期:</label><br>
<input type="date" id="issue_date" name="issue_date"><br>
<input type="submit" value="提交">
</form>
</body>
</html>
5，访问页面
http://127.0.0.1:8000/app8/add_data/
<!DOCTYPE html>
<html>
<head>
<title>插入数据</title>
</head>
<body>
<form method="post">
{% csrf_token %}
<label for="name">姓名:</label><br>
<input type="text" id="name" name="name"><br>
<label for="age">年龄:</label><br>
<input type="text" id="age" name="age"><br>
<label for="passport_number">护照号码:</label><br>
<input type="text" id="passport_number" name="passport_number"><br>
<label for="issue_date">发行日期:</label><br>
<input type="date" id="issue_date" name="issue_date"><br>
<input type="submit" value="提交">
</form>
</body>
</html>
可以看到插入的数据成功落库了
