Django 2.2 自定义用户模型（密码总是不匹配）

772

创建自定义用户模型并在管理面板中注册新用户后！！！无法从网站登录，错误 -请输入正确的邮件和密码。两个地方都要注意大小写。

Python 3.7，Django 2.2，站点上不允许用户注册，只能从管理面板并且只能由管理员进行。

我注意到了这一刻（有些东西告诉我这就是问题所在）。如果您进入管理配置文件中的管理面板，则密码将以散列形式显示，并且以文本形式为用户显示：

    def clean_password2(self):
        password1 = self.cleaned_data.get('password1')
        password2 = self.cleaned_data.get('password2')

        if password1 and password2 and password1 != password2:
            raise forms.ValidationError('Пароли не совпадают')

您的问题是您仅在 commit==True 时保存用户

        user = super().save(commit=False)
        user.set_password(self.cleaned_data['password1']) 

        if commit: # Не работает из-за этого. Уберите и будет счастье. Почему - см. ниже
            user.save()

更新到


    def save(self, *args, **kwargs):
        user = super().save(*args, **kwargs)
        user.set_password(self.cleaned_data['password1'])
        user.save()

模型管理员

# django.contrib.admin.options.ModelAdmin
# 969 строка

    def save_form(self, request, form, change):
        """
        Given a ModelForm return an unsaved instance. ``change`` is True if
        the object is being changed, and False if it's being added.
        """
        return form.save(commit=False)
