python - Django 错误：没有这样的表，即使在进行迁移之后

问题描述

我在访问http://127.0.0.1:8000/orders/create/时遇到操作错误

我得到的错误：

OperationalError at /orders/create/
no such table: orders_order

我已经尝试过进行迁移。但问题不会消失

我的 models.py 看起来像这样：

from django.db import models
from ecom.models import Product

# Create your models here.

class Order(models.Model):
    first_name = models.CharField(max_length=50)
    last_name = models.CharField(max_length=50)
    email = models.EmailField()
    address = models.CharField(max_length=250)
    postal_code = models.CharField(max_length=20)
    city = models.CharField(max_length=100)
    created = models.DateTimeField(auto_now_add=True)
    updated = models.DateTimeField(auto_now=True)
    paid = models.BooleanField(default=False)

    class Meta:
        ordering = ('-created',)

    def __str__(self):
        return 'Order {}'.format(self.id)

    def get_total_cost(self):
        return sum(item.get_cost() for item in self.items.all())

#item info 
class OrderItem(models.Model):
    order = models.ForeignKey(Order, related_name='items',on_delete=models.PROTECT)
    product = models.ForeignKey(Product,related_name='order_items',on_delete=models.PROTECT)
    price = models.DecimalField(max_digits=10, decimal_places=2)
    quantity = models.PositiveIntegerField(default=1)

    def __str__(self):
        return '{}'.format(self.id)

    def get_cost(self):
        return self.price * self.quantity

我的views.py 看起来像这样：

from django.shortcuts import render
from .models import OrderItem
from .forms import OrderCreateForm
from cart.cart import Cart

# Create your views here.
def order_create(request):
    cart = Cart(request)
    if request.method == 'POST':
        form = OrderCreateForm(request.POST)
        if form.is_valid():
            order = form.save()
            for item in cart:
                OrderItem.objects.create(order=order, product=item['product'], price=item['price'], quantity=item['quantity'])
            # clear the cart            
            cart.clear()
            return render(request, 'order/created.html', {'order': order})
    else:
        form = OrderCreateForm()
        return render(request, 'order/create.html', {'cart': cart, 'form': form})

Django 突出显示的行：

order = form.save()

解决方案

python manage.py migrate 我通过运行来修复它python manage.py makemigrations orders。还要确保您的应用程序包含在settings.py文件中。
