Django 页面展示模型创建表的数据

1，添加视图函数

Test/app8/urls.py

from django.shortcuts import render
from .models import Userdef 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, Passportdef 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 datetimedef 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')def show_data(request):people = Person.objects.all()return render(request, '8\show_data.html', {'people': people})

2，添加路由地址

Test/app8/urls.py

from django.urls import path
from . import viewsurlpatterns = [path('create_user', views.create_user, name='create_user'),path('delete_person/<int:person_id>/', views.delete_person, name='delete_person'),path('add_data/', views.add_data, name='add_data'),path('show_data/', views.show_data, name='show_data'),
]

3，访问页面

http://127.0.0.1:8000/app8/show_data/

4，优化代码实现分页

4.1 修改视图函数

from django.core.paginator import Paginator
from django.shortcuts import renderdef show_data2(request):people_list = Person.objects.all()paginator = Paginator(people_list, 10)  # 每页显示10条数据page_number = request.GET.get('page')people = paginator.get_page(page_number)return render(request, '8\show_data2.html', {'people': people})

4.2 修改html代码

Test/templates/8/show_data2.html

<!DOCTYPE html>
<html>
<head><title>显示数据</title>
</head>
<body><table><tr><th>姓名</th><th>年龄</th><th>护照号码</th><th>发行日期</th></tr>{% for person in people %}<tr><td>{{ person.name }}</td><td>{{ person.age }}</td><td>{{ person.passport.passport_number }}</td><td>{{ person.passport.issue_date }}</td></tr>{% endfor %}</table><div class="pagination"><span class="step-links">{% if people.has_previous %}<a href="?page=1">&laquo; 第一页</a><a href="?page={{ people.previous_page_number }}">上一页</a>{% endif %}<span class="current">页码: {{ people.number }} / {{ people.paginator.num_pages }}</span>{% if people.has_next %}<a href="?page={{ people.next_page_number }}">下一页</a><a href="?page={{ people.paginator.num_pages }}">最后一页 &raquo;</a>{% endif %}</span></div>
</body>
</html>

4.3 修改路由地址

Test/app8/urls.py

from django.urls import path
from . import viewsurlpatterns = [path('create_user', views.create_user, name='create_user'),path('delete_person/<int:person_id>/', views.delete_person, name='delete_person'),path('add_data/', views.add_data, name='add_data'),path('show_data/', views.show_data, name='show_data'),path('show_data2/', views.show_data2, name='show_data2'),
]
