How to use the field "email" as "username" in django?

Hello everyone I am new to django and I am creating a project where I created a database with a table "tblusuarios" and managed to insert the necessary data such as name, surname, email, password, however, when I go to make the login I am using the field "mail" as username, but so far fails to make the login. Any advice you can offer me?
User model:

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'

View function:

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)

Login form:

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

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

          alt="Login image"
          class="w-100 vh-100"
          style="object-fit: cover; object-position: left"
        />
      </div>
    </div>
  </div>
</section>
{% endif %}
{% endblock content %}

So as I say, always the variable "user" in the view function comes as "none".

I added the "USERNAME_FIELD" variable to my user model, however it did not work.

As far as I know you should not inherit both from AbstractBaseUser and models.Model. See working example from docs :

Code sample :

from django.contrib.auth.models import AbstractBaseUser
from django.db import models


class MyUser(AbstractBaseUser):
    identifier = models.CharField(max_length=40, unique=True)
    ...
    USERNAME_FIELD = "identifier"

Also in your settings do not forget to precise the user model you want to use with the AUTH_USER_MODEL, reference here.

In your settings.py :

# ...
AUTH_USER_MODEL = "path.to.your.model.YourCustomUserModel"
# ...

I think it's better this way. I do it like this, but I don't know about the login part because I write it differently. Please do it this way, and if it doesn't work, let me know here.

from mymodel import TblUsuarios

def login_user(request):
    if request.method == 'POST':
        correo = request.POST.get['email']
        password = request.POST.get['password']
        if correo != '' and password != ''
            if TblUsuarios.objects.filter('email' = email).exists():            #If the email was in the database 
                TblUsuariosObject = TblUsuarios.objects.get('email' = email)    #Get Object with entered email
                if TblUsuariosObject.password == password:                      #check this email password == password in input
                    print(TblUsuariosObject.correo)
        # 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:
                messages.error(request, 'dont have this email in the Database')
                return redirect('login')
        else:
            messages.error(request, 'Null Inputs')
            return redirect('login')
    else:
        context = {}
        return render(request, 'users/login.html', context)
