Having a following followers problem in Django "too many values.." - django-models

Question

I'm about to finish a Django based project, and the last step of this project is to build a followers/following feature. I can unfollow someone I've followed manually from the admin, but I can't follow someone from my html view. It misses me just one tiny thing to add into my html code but I'm really stuck. My code
My Model:
from django.db import models
from django.contrib.auth.models import AbstractUser
# Create your models here.
class User(AbstractUser):
CREATOR = "CREATOR"
SUBSCRIBER = "SUBSCRIBER"
ROLE_CHOICES = (
(CREATOR, "Créateur"),
(SUBSCRIBER, "Abonné"),
)
profile_photo = models.ImageField(upload_to='profile_photos/', default='profile_photos/default.png', blank=True, null=True)
role = models.CharField(max_length=10, choices=ROLE_CHOICES, default=SUBSCRIBER)
follows = models.ManyToManyField('self', related_name='followers', symmetrical=False)
My Views:
#login_required
def abonnements(request):
user = request.user
followers = user.followers.all()
follows = user.follows.all()
if request.method == 'POST':
if request.POST.get('follow'):
if request.POST.get('follow') == user.username:
return render(request, 'blog/abonnements.html', {'followers': followers, 'follows': follows, "error": "You can't follow yourself!"})
try:
followed_user = User.objects.get(request.POST.get('follow'))
except User.DoesNotExist:
return render(request, 'blog/abonnements.html', {'followers': followers, 'follows': follows, "error": "User does not exist"})
else:
print(followed_user)
elif request.POST.get('unfollow'):
user.follows.remove(User.objects.get(pk=request.POST.get('unfollow')))
return render(request, 'blog/abonnements.html', {'followers': followers, 'follows': follows, "success": "You are no longer following " + request.POST.get('unfollow')})
return render(request, 'blog/abonnements.html', {'followers': followers, 'follows': follows})
My HTML
{% extends 'base.html' %}
<title>{% block title %}Abonnements{% endblock %}</title>
{% block content %} {% include 'partials/_navbar.html' %}
<main class="corps_abonnements">
<section class="suivre">
<p class="suivre_utilisateurs_titre">Suivre d'autres utilisateurs</p>
<form method="post">
{% csrf_token %}
<input type="text" name="follow" value="">
<input type="submit" value="Envoyer">
</form>
</section>
<section class="abonnements">
<p color="red">{{ error }}</p>
{% if success %}<p color="green">{{ success }}</p>{% endif %}
<p class="abonnements_titre">Abonnements</p>
{% for user in follows %}
<div class="utilisateur_desabonner_container">
<p class="nom_utilisateur_desabonner">{{ user.username }}</p>
<form method="post">
{% csrf_token %}
{% if user in follows %}
<input type="hidden" name="unfollow" value="{{ user.id }}">
<button style="background-color:red;" type="submit" class="creer_critique_demande">
Se désabonner
</button>
{% endif %}
</form>
</div>
{% endfor %}
</section>
<section class="abonnes">
<p class="abonnes_titre">Abonnés</p>
{% for user in followers %}
<div class="utilisateur_abonne_container">
<p class="nom_utilisateur_abonne">{{ user.username }}</p>
</div>
{% endfor %}
</section>
</main>
{% endblock %}
So when I put the connected user name in the input, it returns me the error "you can't follow yourself", it means that my code is good
the message
but If I try to put the username of another user I want to follow, it raises me an error. Can someone help me please ?
