Django开发物流web应用(二)-订单系统构建

1. setting.py配置

DEBUG = True: 是否为调试模式
INSTALLED_APPS: 已安装的Django应用
DATABASES: 使用的数据库

修改时区和语言

LANGUAGE_CODE = 'zh-hans'
TIME_ZONE = 'Asia/Shanghai'

2. 执行数据迁移

新创建的app需要创建一些数据表

运行:
python manage.py migrate

编辑 orders/models.py

class Order(models.Model):

    def __str__(self):
        return self.name

    name = models.CharField(max_length=200)
    sender = models.CharField(max_length=200)
    recipient = models.CharField(max_length=200)
    position = models.CharField(max_length=200)
    status = models.CharField(max_length=200)

将app添加至settings

INSTALLED_APPS = [
    ...
    'orders.apps.OrdersConfig',
]

最后执行数据库迁移

3. Django管理员

运行 python manage.py createsuperuser

并在 orders/admin.py里注册模型

...
from . models import Order

...
admin.site.register(Order)

4. 前端展示, 并添加订单

前端html页面:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>
</head>
<body>
    {% for order in orders %}
        <div>{{ order.name }}<div>
    {% empty %}
        <div>no orders<div>
    {% endfor %}
    <form action="/orders/" method="post">{% csrf_token %}
        <input type="text" name="order_name">
        <input type="text" name="order_sender">
        <input type="text" name="order_recipient">
        <input type="text" name="order_position">
        <input type="text" name="order_status">
        <input type="submit" value="提交">
    </form>
</body>
</html>

views.py

from django.shortcuts import render
from django.http import HttpResponse
from .models import Order


def create_order(request):
    new_order = Order()
    name = request.POST.get('order_name', '')
    sender = request.POST.get('order_sender', '')
    recipient = request.POST.get('order_recipient', '')
    position = request.POST.get('order_position', '')
    status = request.POST.get('order_status', '')
    new_order.name = name
    new_order.sender = sender
    new_order.recipient = recipient
    new_order.position = position
    new_order.status = status
    new_order.save()


def order_list(request):
    request.encoding='utf-8'
    if request.POST.get('order_name'):
        create_order(request)
    all_orders = Order.objects.all()
    context = {}
    context['orders'] = all_orders
    return render(request, 'orders/order_list.html', context)


def index(request):
    return HttpResponse("Hello")
