Cant uploading data through foreign key with crispy forms - django

Question

I am uploading a photo by using a foreign key in forms but I didn't get any data in a database and I didn't get any errors.
models.py
from django.db import models
class username(models.Model):
name=models.CharField(max_length=100)
phone=models.BigIntegerField()
email=models.EmailField(max_length=100)
class Profilephoto(models.Model):
profile_photo = models.FileField(upload_to='media/')
uname = models.ForeignKey(username, on_delete=models.CASCADE, null=True)
forms.py
from django import forms
from .models import Profilephoto
class DocumentForm(forms.ModelForm):
class Meta:
model = Profilephoto
fields = ['profile_photo','uname']
view.py
from django.shortcuts import render, redirect, HttpResponse
from .models import username,Profilephoto
from .form import DocumentForm
def home(request):
if request.method == 'POST':
name = request.POST['name']
phone = request.POST['phone']
email = request.POST['email']
username(name=name,phone=phone,email=email).save()
users = username.objects.latest('id')
return render(request, 'home.html',{'usernames': users})
else:
users = username.objects.latest('id')
return render(request, 'home.html',{'usernames': users})
def data1(request,id):
if request.method == 'GET':
obj = username.objects.get(id=id)
form = DocumentForm(instance=obj)
return render(request, 'data1.html', {'form': form, 'usernames': obj})
elif request.method == 'POST':
obj = username.objects.get(id=id)
form = DocumentForm(request.POST, request.FILES, instance=obj)
if form.is_valid():
form.save()
return redirect('home')
return render(request, 'data1.html', {'usernames': obj})
data1.html
<form method="post" enctype="multipart/form-data">
{% csrf_token %}
{{ form|crispy }}
<div align="center">p
<button type="submit" class="btn btn-primary">Submit</button>
</div>
</form>
Please Help me Thanks in Advance

It's happening because your DocumentForm is form of model Profilephoto and in view function you are passing Username's instance.
so in your views.py, try this:
def data1(request,id):
if request.method == 'GET':
obj = username.objects.get(id=id)
form = DocumentForm()
return render(request, 'data1.html', {'form': form, 'usernames': obj})
elif request.method == 'POST':
obj = username.objects.get(id=id)
form = DocumentForm(request.POST, request.FILES)
if form.is_valid():
form.save()
return redirect('home')
return render(request, 'data1.html', {'usernames': obj})
