Form validation is done when you submit form using post request. The code you are showing is for rendering forms, you need a different view to handle the form submissions. You can do it like this:
Modify Form __init__
def __init__(self, *args, **kwargs):
self.voter = kwargs.pop('user', None)
self.round = kwargs.pop('round', None)
super(PlayerVotesForm, self).__init__(*args, **kwargs)Modify your current View:
# inside your votes view
for game in fixtures:
games[game] = forms.PlayerVotesForm(user=request.user, round=game)
return render(request, 'votes/display.html', context={'games':games})Template
{% for game, form in games.items %}
<h1> {{ game.round }} h1>
...
<form action="{% url 'cast-vote' game.pk %}" method="post">
{{ form.as_p }}
<input type="submit" value="OK">
form>
{% enfor %}Now you need to handle the form submission given above:
View
def cast_vote(request, pk):
game = get_object_or_404(Game, pk=pk)
if request.method == "POST":
form = PlayerVotesForm(request.POST, user=request.user, round=game)
if form.is_valid():
# do other logics
return redirect('votes-url')Url
path('castvote//' , cast_vote, name="cast-vote")No matter what stage you're at in your education or career, TuteeHUB will help you reach the next level that you're aiming for. Simply,Choose a subject/topic and get started in self-paced practice sessions to improve your knowledge and scores.

I have two models, "Fixture" and "PlayerVotes". The PlayerVotes model has two foreign keys, a link to a particular fixture and the voter (request.user).
I want to display the entire list of fixture as an expandable accordion (bootstrap4) and allow the logged in user to give some votes for each instance of fixture. I am not sure where I could have the form validation and the save() functions.
