python - 意外的关键字参数

问题描述

这是我的模型 模型

from Account.models import User
from django.db import models

class Seller(models.Model):
    seller = models.OneToOneField(User, on_delete = models.CASCADE)
    email = models.EmailField(max_length = 90, unique = True)
    country = models.CharField(max_length = 60)
    phone = models.CharField(max_length= 20, unique = True, blank = True, null = True)
    address = models.TextField()
    zipcode = models.CharField(max_length = 10)

形式

from django import forms
from django.contrib.auth.forms import UserCreationForm
from django.db import transaction
from .models import Seller
from Account.models import User

class SellerCreationForm(UserCreationForm):
    name = forms.CharField(required = True)
    email = forms.EmailField(required = True)
    phone = forms.CharField(required = False)
    country = forms.CharField(required = True)
    address = forms.CharField(required = True)
    zipcode = forms.CharField(required = True)

    class Meta(UserCreationForm.Meta):
        model = User

    @transaction.atomic
    def save(self):
        user = super().save(commit=False)
        user.is_seller = True
        user.name = self.cleaned_data.get('name')
        user.save()
        seller = Seller.objects.create(user=user)
        seller.email = self.cleaned_data.get('email')
        seller.phone = self.cleaned_data.get('phone')
        seller.country = self.cleaned_data.get('country')
        seller.address = self.cleaned_data.get('address')
        seller.zipcode = self.cleaned_data.get('zipcode')
        seller.save()
        return user

意见

from django.shortcuts import render, redirect
from django.views.generic import CreateView
from .forms import SellerCreationForm
from django.contrib.auth.forms import AuthenticationForm
from Account.models import User

class RegisterSeller(CreateView):
    model = User
    form_class = SellerCreationForm
    template_name = 'registration/registerseller.html'

    def form_valid(self, form):
        user = form.save()
        login(self.request, user)
        return redirect('/')

我尝试创建一个具有多种用户类型且所有用户具有不同功能的项目。 代码中的所有内容都运行良好，但每当我尝试注册新用户时，都会出现错误。它说 Seller() 得到了一个意想不到的关键字参数“用户”

解决方案

从ForeignKey到Seller已User命名seller，而不是seller`。因此，您可以构造一个对象：

seller = Seller.objects.create(
    seller=user,
    email=self.cleaned_data['email']
    phone = self.cleaned_data['phone']
    country = cleaned_data['country']
    address = self.cleaned_data['address']
    zipcode = self.cleaned_data['zipcode']
)

但也许最好将该字段重命名为：

from Account.models import User
from django.db import models

class Seller(models.Model):
    user = models.OneToOneField(User, on_delete = models.CASCADE)
    # ⋮

注意：通常使用settings.AUTH_USER_MODEL[Django-doc]引用用户模型比直接使用User模型 [Django-doc]更好。有关更多信息，您可以查看文档的引用User模型部分。
