我正在做一个Django项目,我想得到一个属性为OneToOne的Related模型的ID,这样我就可以用相关的Profile编辑用户的Profile,但我得到的回报是字段'id'应该是一个数字,但得到的是'GANDE1'。
以下是我的模型:
class Profile(models.Model):
customer = models.OneToOneField(User, on_delete=models.CASCADE, null = True)
surname = models.CharField(max_length=20, null=True)
othernames = models.CharField(max_length=40, null=True)
gender = models.CharField(max_length=6, choices=GENDER, blank=True, null=True)
address = models.CharField(max_length=200, null=True)
phone = models.CharField(max_length=11, null=True)
image = models.ImageField(default='avatar.jpg', blank=False, null=False, upload_to ='profile_images',
)
#Method to save Image
def save(self, *args, **kwargs):
super().save(*args, **kwargs)
img = Image.open(self.image.path)
#Check for Image Height and Width then resize it then save
if img.height > 200 or img.width > 150:
output_size = (150, 250)
img.thumbnail(output_size)
img.save(self.image.path)
def __str__(self):
return f'{self.customer.username}-Profile'
class Account(models.Model):
customer = models.OneToOneField(User, on_delete=models.CASCADE, null=True)
account_number = models.CharField(max_length=10, null=True)
date = models.DateTimeField(auto_now_add=True, null=True)
def __str__(self):
return f' {self.customer} - Account No: {self.account_number}'
以下是我的看法:
def create_account(request):
#Search Customer
if searchForm.is_valid():
#Value of search form
value = searchForm.cleaned_data['value']
#Filter Customer by Surname, Othernames , Account Number using Q Objects
user_filter = Q(customer__exact = value) | Q(account_number__exact = value)
#Apply the Customer Object Filter
list_customers = Account.objects.filter(user_filter)
else:
list_customers = Account.objects.all()
context = {
'customers':paged_list_customers,
}
return render(request, 'dashboard/customers.html', context)
下面是我如何显示帐户列表中我的模板:
{% for customer in customers %}
<tr>
<td>{{ forloop.counter }}</td>
<td>{{ customer.account_number }}</td>
{% if customer.customer.profile.surname == None %}
<td> <a class="btn btn-danger" href=" {% url 'update-customer' customer.customer.id %} ">Click to Enter Customer Personal Details.</a> </td>
{% else %}
<td>{{ customer.customer.profile.surname }} {{ customer.customer.profile.othernames }}</td>
<td>{{ customer.customer.profile.phone }}</td>
<td><a class="btn btn-success btn-sm" href="{% url 'account-statement' customer.id %}">Statement</a></td>
<td><a class="btn btn-danger btn-sm" href="{% url 'dashboard-witdrawal' customer.id %}">Withdraw</a></td>
<th scope="row"><a class="btn btn-success btn-sm" href="{% url 'create-deposit' customer.id %}">Deposit</a></th>
{% endif %}
</tr>
{% endfor %}
这是我遇到问题的客户更新视图:
def update_customer_profile(request, pk):
#get logged in user
user = request.user
#check if logged in user is staff
try:
customer_user = User.objects.get(id=pk)
except User.DoesNotExist:
return redirect('user-register')
else:
count_users = User.objects.count()
#Get the Customer User's Profile from the User above
user_profile = Profile.objects.get(customer=customer_user.username)
请理解,我想得到一个用户的ID,并与他的个人资料记录中的一个匹配,这样我就可以编辑他的个人资料记录。还请注意,客户资料是自动创建的用户注册后使用的信号。谢谢期待您的亲切回答。

如果您已经有了
User
对象,那么只需使用它们之间的关系:你不需要单独查询数据库。这正是关系的作用。
