Why Django's POST doesn't do anything - not even an error?
Question
I'm doing an assignment for Uni from Python/Django. One of the things I have to do is to create a form where a user can create a new "tournament" on the website. Frontend doesn't matter at all.
I created a model, added some tournaments from the Admin panel and that works fine. But when I try to create a new tournament from the form, and click the sumbit button, I get redirected to my home page (even though nothing specifies in the HTML or views.py that this should happen), I get no error, no data posted and no info back from the command line.
models.py
class Tournament(models.Model):
title = models.CharField(max_length=30)
creator = models.OneToOneField(User, on_delete=models.CASCADE)
players = models.ManyToManyField(User, related_name="players",)
created_date = models.DateField(auto_now=True)
start_date = models.DateField(auto_now=True)
max_players = models.IntegerField(
null=True, validators=[MinValueValidator(2), MaxValueValidator(64)])
slug = models.SlugField(unique=True, db_index=True)
def __str__(self):
return f"{self.title} \n {self.creator} \n {self.max_players}"
Forms.py
class TournamentForm(forms.ModelForm):
class Meta:
model = Tournament
#exclude = ["slug"]
fields = "__all__"
views.py
class TournamentView(View):
def get(self, request):
form = TournamentForm()
print(form.errors)
return render(request, "tournament_app/new_tournament.html", {
"form": form
})
def post(self, request):
form = TournamentForm(request.POST)
if form.is_valid():
print(form.errors)
form.save()
return redirect("/thank-you")
print(form.errors)
return render(request, "tournament_app/new_tournament.html", {
"form": form
})
new_tournament.html
{% extends "base.html" %}
{% block title %} Create New tournament {% endblock title %}
{% extends "base.html" %}
{% block title %}
Create New tournament
{% endblock title %}
{% block content %}
<form action="/" method="POST">
{% csrf_token %}
{% for field in form%}
<div class="form-control">
{{field.label_tag}}
{{field}}
</div>
{% endfor %}
<button type="submit">Send</button>
</form>
base.html
<!DOCTYPE html>
<html lang="en">

<body>
{% if user.is_authenticated %}
<p style="text-align:right;">You are logged in as <b>{{user.username}}</b></p>
{% else %}
<p style="text-align:right;"><b>Anonymous user</b></p>
{% endif %}
<a href="{% url "index-page" %}"><button type = "button"> Main Page </button></a>
<a href="{% url "login" %}"><button type = "button"> Login </button></a>
{% block content %}{% endblock content %}
</body>
</html>
As you can see in the views.py I tried to check for at least any errors as suggested on some other post years ago, but I get NO response back. In the command line i see it as such:
[22/Jul/2021 13:33:10] "GET /new-tournament HTTP/1.1" 200 1839
[22/Jul/2021 13:33:19] "POST / HTTP/1.1" 200 744
I have absolutely no experience in WebDev and no experience in Django. Can you please help me identify problem? If there was at least some error response or anything like that.

I get redirected to my home page (even though nothing specifies in the HTML or views.py that this should happen)
Oh, but you're specifying that, quite explicitly. :-)
You're POSTing to / , not /new-tournament (your TournamentView).
<form action="/" method="POST">
Get rid of the action to post to the current URL instead.
<form method="POST">
Additionally, you can simplify your TournamentView to a CreateView :
class TournamentView(CreateView):
model = Tournament
template_name = "tournament_app/new_tournament.html"
success_url = "/thank-you"
(yes, that should be all)
