更改用户详细信息时 UNIQUE 约束失败用户名错误

Question

我通过扩展 AbstractUser class 来自定义用户模型。我想制作表格来更改用户的全名和网站字段。我的用户：

class Hacker(AbstractUser):
    name = models.CharField(max_length=255)
    team = models.ForeignKey(Team, on_delete=models.CASCADE, blank=True, null=True)
    description = models.CharField(max_length=255, blank=True, null=True)
    website = models.URLField(max_length=200, blank=True, null=True)

    def __str__(self):
        if self.name:
            return self.name
        else:
            return self.username

和forms.py：

class ProfileForm(forms.ModelForm):
    """
    Edit profile form
    """
    name = forms.CharField(label=_("Name"),
                           widget=forms.TextInput(attrs={'placeholder': _('Name')}))
    description = forms.CharField(label=_("Description,Position"), required=False,
                                  widget=forms.TextInput(attrs={'placeholder': _('Description, Position')}))
    website = forms.URLField(label=_("Website"), required=False,
                             widget=forms.TextInput(attrs={'placeholder': _('Website URL')}))

    class Meta:
        model = get_user_model()
        fields = ['name', 'description', 'website']

在页面中，我使用 {{ field }} 添加输入，在 POST 部分视图中：

form = ProfileForm(request.POST)
    if form.is_valid():
        form.save(commit=True)
        ...

但是 form.save 给出 UNIQUE constraint failed: common_hacker.username 错误。这里可能有什么问题？

创建表单时添加instance=request.user修复问题：

form = ProfileForm(request.POST, instance=request.user)
