django default Authenticaiton form shows username rather than email - django

Question

I implemented my own user login form with django like below
from django.contrib.auth.forms import AuthenticationForm
class CustomUserLoginForm(AuthenticationForm):
class Meta:
model = CustomUser
fields = ('email', 'password')
then as a view this is what I have:
from rest_auth.views import LoginView
from users.forms import CustomUserLoginForm
class CustomLoginView(LoginView):
def get(self, request):
form = CustomUserLoginForm()
return render(request, "api/test_template.html", context={"form": form})
in my template then, I am calling {{form.as_p}} in <form> tag to show the form input details.
However, by default, this shows the username and password forms. How can I replace the username with the email?
in the rest-auth, browserable api, both the username and the email are present so I know that I can do this since I am using the rest-auth LoginView as backend.
Can I manually unpack {{form}} since later I would still like to style this form. How can I do this?
update
I unpacked the form in `api/test_template.html myself which now looks like the below:
{% block content %}
<div class="container">
<form method="POST">
{% csrf_token %}
<div>
<label for="{{ form.email.id_for_label }}">Email: </label>
<input{{ form.email }}>
</div>
<div>
<label for="{{ form.password.id_for_label }}">password: </label>
<input type="password" {{ form.password }}>
</div>
<button style="background-color:#F4EB16; color:blue" class="btn btn-outline-info" type="submit">Login</button>
</form>
Don't have an account? <strong>register here</strong>!
</div>
{% endblock %}
this works, however, rest-auth framework still require the username to not be empty. how can I change that, to ignore the username?
my user model
from django.contrib.auth.models import AbstractUser
from django.db import models
class CustomUser(AbstractUser):
def __str__(self):
return self.email

Answer 1

You should set USERNAME_FIELD='email' on your CustomUser model.
There is nice blogpost on How to use email as username.
