When using Django the save() function does not work using model forms

Question

Im trying to learn Django. I believe my form is working properly but the data is not saved into the database.

This is my model:

from django.db import models

# Create your models here.
class parameters(models.Model):
    interval_1 = models.PositiveIntegerField()
    interval_2 = models.PositiveIntegerField()
    interval_3 = models.PositiveIntegerField()
    interval_4 = models.PositiveIntegerField()
    interval_5 = models.PositiveIntegerField()
    interval_6 = models.PositiveIntegerField()
    cost_1 = models.DecimalField(max_digits=19, decimal_places=2)
    cost_2 = models.DecimalField(max_digits=19, decimal_places=2)
    cost_3 = models.DecimalField(max_digits=19, decimal_places=2)
    cost_4 = models.DecimalField(max_digits=19, decimal_places=2)
    cost_5 = models.DecimalField(max_digits=19, decimal_places=2)
    cost_6 = models.DecimalField(max_digits=19, decimal_places=2)

This is my form:

from django import forms
from django.forms import ModelForm

from .models import parameters

# Create your forms here.

class set_parameters(forms.ModelForm):
    class Meta:
        model = parameters
        fields = "__all__"

This is my view:

from django.shortcuts import render

# Create your views here.
from .models import parameters
from .forms import set_parameters

def frequence_create_view(request):
    form = set_parameters(request.POST or None)
    if form.is_valid():
        form.save()
        print(request)
        print(form)
        form = set_parameters()
    else:
            print (form.errors)

    context = {
        'form': form
    }
    return render(request, 'settings/settings.html', context)

These are my templates:

<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
</head>
<body>
    {% block frequence %}
    {% endblock %}
    {% block cost %}
    {% endblock %}
</body>
</html>

{% extends 'base.html' %}
{% block frequence %}
<form action='.' method='POST'> {% csrf_token %}
    {{ form.as_p }}
    <input type='submit' value='save' />
</form>
{% endblock %}

And this is my URL's

from django.contrib import admin
from django.urls import path
from settings.views import frequence_create_view

urlpatterns = [
    path('admin/', admin.site.urls),
    path('frequence_create/', frequence_create_view),
]

The problem I have is that when i submit the form the information is not stored in the database.

Can somebody try to explain what the problem is?

have you seen any form errors?

correct your code as shown, which will handle the get request too

def frequence_create_view(request):
    if request.method == "POST":
        form = set_parameters(request.POST or None)
        if form.is_valid():
           form.save()
           return redirect('/')
    else:
        form = set_parameters()
    return render(request, 'your.html', {'form': form})
