Question

我通过扩展AbstractUser类来拥有自定义用户模型。我想创建表单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

并且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，并在POST部分视图中使用：

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

但是form.save会出现UNIQUE constraint failed: common_hacker.username错误。这可能有什么问题？

在创建表单已修复问题时添加instance=request.user：

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

更改用户详细信息时UNIQUE约束失败用户名错误
