To my code, which records a contact from the form and adds it to the db, need to add get_or_create, or write another condition (if there is a contact with such a phone — update, no - add), but i'm do it for the first time, please, I'll be glad to read solution to my problem and a brief explanation ♡
views.py
from django.http import HttpResponse
from django.shortcuts import render,redirect
from django.contrib import messages
from .forms import Forms
def main(request):
form = Forms
if request.method == "POST":
form = Forms(request.POST)
if form.is_valid():
form.save()
messages.success(request, 'Form has been submitted')
return redirect('/')
return render(request, 'app/main.html', { 'form':form } )
forms.py
from django.forms import ModelForm
from .models import Form
class Forms(ModelForm):
class Meta:
model = Form
fields = '__all__'

You can implement this with:
def main(request):
if request.method == "POST":
form = Forms(request.POST)
if form.is_valid():
Form.objects.get_or_create(
phone=form.cleaned_data['phone'],
defaults={'name': form.cleaned_data['name']}
)
messages.success(request, 'Form has been submitted')
return redirect('/')
else:
form = Forms()
return render(request, 'app/main.html', { 'form': form })You must be careful however since this means that a user might edit data of another user. Perhaps it is thus worth to check if the (logged in) user has rights to update that item.
