大家好，我是django的新手，我正在创建一个项目，我用表“tblusuarios”创建了一个数据库，并设法插入必要的数据，如姓名，姓氏，电子邮件，密码，然而，当我去登录时，我使用字段“mail”作为用户名，但到目前为止未能登录。你能给我什么建议吗？用户型号：

class TblUsuarios(AbstractBaseUser, models.Model):
    nombre = models.CharField(max_length=80)
    apellidos = models.CharField(max_length=80, blank=True, null=True)
    correo = models.CharField(max_length=80, unique=True)
    telefono = models.CharField(max_length=11, blank=True, null=True)
    password = models.CharField(max_length=80)
    foto = models.ImageField(upload_to='images/')
    tbl_roles = models.ForeignKey(TblRoles, models.DO_NOTHING, default=1)

    # object = CustomAccountManager()
    USERNAME_FIELD = 'correo' #le damos el username por defecto a la tabla
    REQUIRED_FIELDS=(['nombre'])
    class Meta:
        db_table = 'tbl_usuarios'

查看功能：

def login_user(request):
    if request.method == 'POST':
        correo = request.POST['email']
        password = request.POST['password']

        user = authenticate(request, username = correo, password = password)
        print(user)
        if user is not None:
            login(request, user)
            messages.info(request, 'Has ingresado correctamente a la aplicacion!!')
            return redirect('home')
        else:
            messages.error(request, 'Ha ocurrido un error a la hora de iniciar sesion!')
            return redirect('login')
    else:
        context = {}
        return render(request, 'users/login.html', context)

登录表单：

{% extends "layouts/layout.html" %} {% block content %}

{% if user.is_authenticated %}
    <h2>Ya estas logueado en nuestra aplicación</h2>
{% else %}

          class="w-100 vh-100"
          style="object-fit: cover; object-position: left"
        />
      </div>
    </div>
  </div>

{% endif %}
{% endblock content %}

因此，正如我所说的，视图函数中的变量“user”总是“none”。
我将“USERNAME_FIELD”变量添加到我的用户模型中，但是它没有起作用。
