python - 如何在 django 中更新卖家资料？
问题描述
我正在开发一个具有两种类型用户的多用户项目。
第一个是卖方，第二个是买方。当卖家注册自己时，它将被重定向到他的个人资料，卖家可以通过提供名字、姓氏、地址等额外凭据来更新其个人资料，但我遇到的主要问题是，当我提供要更新的数据时它什么也没显示。
所以我请求大家为我提供最好的解决方案。我必须在周日晚上之前提交这项工作。
我还为您提供了我的代码，以便大家都能理解我错在哪里。
models.py：
from django.db import models
from accounts.models import Seller
class Profile(models.Model):
CATEGORY_CHOICES = (
('M', 'Male'),
('F', 'Female'),
)
first_name = models.CharField(max_length=200)
last_name = models.CharField(max_length=200)
profile_image = models.ImageField(upload_to='photos/')
date_of_birth = models.DateField()
gender = models.CharField(max_length=200, choices=CATEGORY_CHOICES)
email = models.EmailField(max_length=200)
phone = models.CharField(max_length=200)
address = models.CharField(max_length=200)
# city = models.CharField(max_length=200)
# number = models.CharField(max_length=200)
# zip = models.CharField(max_length=200)
# country = models.CharField(max_length=200)
seller = models.ForeignKey(Seller, on_delete=models.CASCADE)
def __str__(self):
return self.name
注意：我有另一个名为 accounts 的应用程序，其中我有两个模型 1st Seller 和 2nd BuyerOneToOne与User.
计算应用模型：
class Buyer(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE, null=True, related_name='buyer_profile')
bio = models.CharField(max_length=30, blank=True)
location = models.CharField(max_length=30, blank=True)
first_name = models.CharField(max_length=200, null=True, blank=True)
last_name = models.CharField(max_length=200, null=True, blank=True)
profile_image = models.ImageField(upload_to='photos/', null=True, blank=True)
date_of_birth = models.DateField(null=True, blank=True)
phone = models.CharField(max_length=200, null=True, blank=True)
address = models.CharField(max_length=200, null=True, blank=True)
gender = models.CharField(max_length=200, null=True, blank=True)
def __str__(self):
if self.user:
return str(self.user.username)
else:
return 'Buyer Name is null'
class Seller(models.Model):
CATEGORY_CHOICES = (

user = models.OneToOneField(User, on_delete=models.CASCADE, null=True, related_name='seller_profile')
company_name = models.CharField(max_length=100, blank=True)
website = models.CharField(max_length=100, blank=True)
location = models.CharField(max_length=30, blank=True)
first_name = models.CharField(max_length=200, null=True, blank=True)
last_name = models.CharField(max_length=200, null=True, blank=True)
profile_image = models.ImageField(upload_to='photos/', null=True, blank=True)
date_of_birth = models.DateField(null=True, blank=True)
phone = models.CharField(max_length=200, null=True, blank=True)

gender = models.CharField(max_length=200, null=True, blank=True, choices=CATEGORY_CHOICES)

解决方案
我重新设计了models.py，forms.py文件如下：-
models.py # Profile models have all field (contains Buyers and Sellers)
class Profile(models.Model):
CATEGORY_CHOICES = (
('M', 'Male'),
('F', 'Female'),
)
user = models.OneToOneField(User,
on_delete=models.CASCADE)
# is_seller field divide the user from Seller and Buyer
is_seller = models.BooleanField(default=False)
# if 'is_seller' field false then it means user is 'buyer' and vice-versa
profile_image = models.ImageField(upload_to='photos/', blank=True, null=True)
date_of_birth = models.DateField()
gender = models.CharField(max_length=200, choices=CATEGORY_CHOICES, blank=True, null=True)
phone = models.CharField(max_length=200, blank=True, null=True)
address = models.CharField(max_length=200, blank=True, null=True)
# city = models.CharField(max_length=200, blank=True, null=True)
# number = models.CharField(max_length=200, blank=True, null=True)
# zip = models.CharField(max_length=200, blank=True, null=True)
# country = models.CharField(max_length=200, blank=True, null=True)
company_name = models.CharField(max_length=100, blank=True, null=True)
website = models.CharField(max_length=100, blank=True, null=True)
location = models.CharField(max_length=30, blank=True, null=True)
bio = models.CharField(max_length=30, blank=True)
现在在 forms.py 文件中根据用户添加必填字段（即用户是买方或卖方）：-
forms.py
class BuyersForm(forms.ModelForm):
class Meta:
model = Profile
fields = [# Choose and add fields for buyers here]
class SellerForm(forms.ModelForm):
class Meta:
model = Profile
fields = [# Choose and add fields for seller here]
现在，在前端编写用于登录的自定义注册页面（即名字，姓氏，用户名，电子邮件，密码），并且必须有一个选择器（选择卖方或买方）。当用户点击提交时，然后保存所有值to User（即名字、姓氏、用户名、电子邮件、密码）以及 in Profile（即 is_seller 为 True 或 False 并添加 User 实例）。之后（假设用户选择sellerthen）发送SellerForm前端并要求用户填写所需填写的内容。
