我正在尝试将订单归因于我已经创建的特定用户帐户。我已经完成了我在上一个应用程序上执行的过程，但是它无法正常工作，并不断引发以下错误。

我认为这与用户外键的位置有关，但我无法弄清楚或在此处找到与其相关的任何其他帖子。

我的model.py文件如下。

from django.db import models
from babysitters.models import Babysitter
from django.contrib.auth.models import User

class Order(models.Model):
    user = models.ForeignKey(User)
    def __str__(self):
        return "{0}".format(self.date)
        
        
class OrderLineItem(models.Model):
    
    order = models.ForeignKey(Order, null=False)
    babysitter = models.ForeignKey(Babysitter, null=False)
    quantity = models.IntegerField(blank=False)
    price = models.IntegerField(blank=False)
    def __str__(self):
        return "{0} {1} {2} @ {3}".format(self.quantity, self.babysitter.firstName, self.babysitter.quantity, self.babysitter.price)

我的forms.py是

from django import forms
from .models import Order

class MakePaymentForm(forms.Form):

    MONTH_CHOICES = [(i, i,) for i in range(1, 13)]
    YEAR_CHOICES = [(i, i,) for i in range(2018, 2036)]

    
    credit_card_number = forms.CharField(widget=forms.TextInput(attrs= 
    {'placeholder':'Credit card number'}),
    max_length=16, label='Credit card number', required=True)
    expiry_month = forms.ChoiceField(label="Month", choices=MONTH_CHOICES)
    expiry_year = forms.ChoiceField(label="Year", choices=YEAR_CHOICES)
    cvv = forms.CharField(widget=forms.TextInput(attrs= 
    {'placeholder':'cvv'}),
    max_length=3, label='Security code (CVV)', required=True)
    stripe_id = forms.CharField(widget=forms.HiddenInput)
    
    class OrderForm(forms.ModelForm):
    class Meta:
        model = Order
        fields = ('user',)

and views.py是

from django.contrib import messages, auth
from django.contrib.auth.decorators import login_required
from checkout.forms import MakePaymentForm, OrderForm
from django.shortcuts import render, get_object_or_404, redirect, reverse

        payment_form = MakePaymentForm(request.POST)
        if order_form.is_valid() and payment_form.is_valid():
            order = order_form.save(commit=False)
            order.date = timezone.now()
            order.save()
            
            bookings = request.session.get('bookings', {})
            total = 0
            for id, quantity in bookings.items():
                babysitter = get_object_or_404(Babysitter, pk=id)
                total += quantity * babysitter.price
                order_line_item = OrderLineItem(
                    order = order, 
                    babysitter = babysitter, 
                    quantity = quantity
                    )
                order_line_item.save()
                
            try:
                customer = stripe.Charge.create(
                    amount = int(total * 100),
                    currency = "EUR",
                    description = request.user.email,
                    card = payment_form.cleaned_data['stripe_id'],
                )
            except stripe.error.CardError:
                messages.error(request, "Your card was declined!")
                
            if customer.paid:
                messages.error(request, "You have successfully paid")
                request.session['cart'] = {}
                return redirect(reverse('products'))
            else:
                messages.error(request, "Unable to take payment")
        else:
            print(payment_form.errors)
            messages.error(request, "We were unable to take a payment with that card!")
    else:
        payment_form = MakePaymentForm()
        order_form = OrderForm()
        
    return render(request, "checkout.html", {'order_form': order_form, 'payment_form': payment_form, 'publishable': settings.STRIPE_PUBLISHABLE})
    
    stripe.api_key = settings.STRIPE_SECRET

有人可以帮助我还是告诉我我要怎么做？这是我正在研究的项目的最后一部分，令人头疼。

Answer 1

此错误表明数据库没有“ user_id”列，因此您可能尚未创建最新迁移或未针对数据库运行它们。我建议在您的项目文件夹中运行以下命令：

$ python manage.py makemigrations
$ python manage.py migrate

关系“ checkout_order”的列“ user_id”不存在
