Modelforms : not able to view the editable content while updating - django

Question

Possibly a newbie question, so please bear with me.
I have a Django form that edits a certain instance of a Model. I am using Modelforms. I am able to edit the instance but I am not able to see the content of instance that I want to edit.
I am learning django right now using video tutorials and in the tutorial adding instance=instance to ModelForm instance and then using form.as_p the values were populated in the input box.
In my case when I got to edit url my input fields are blank. However, whatever I write in new blank form gets updated to that object. What could have been wrong here? I am stuck at this point for 4 days so this question is a very desperate one :)
My form class:
from django import forms
from .models import Entry
class EntryForm(forms.ModelForm):
class Meta:
model = Entry
fields = ['name','type', 'date', 'description']
My Model:
from django.db import models
class Entry(models.Model):
name = models.CharField(max_length=200)
type = models.CharField(max_length= 200)
date = models.DateTimeField()
description = models.TextField()
My views look like this :
def update(request,pk):
instance = get_object_or_404(Entry,pk=pk)
if request.method == 'POST':
form = EntryForm(request.POST or None,instance=instance )
if form.is_valid():
instance =form.save(commit=False)
instance.save()
return HttpResponseRedirect('/')
else:
form = EntryForm()
return render(request, "form.html", {"name":instance.name,'instance':instance,'form': form})
Form template :
<form method="POST">
{% csrf_token %}
{{form.as_p}}
<button class="btn btn-success" type='submit'>Submit</button>
</form>

You are not passing the instance for the second case. Update your views.py to this.
def update(request,pk):
instance = get_object_or_404(Entry,pk=pk)
if request.method == 'POST':
form = EntryForm(request.POST or None,instance=instance )
if form.is_valid():
instance =form.save(commit=False)
instance.save()
return HttpResponseRedirect('/')
else:
form = EntryForm(instance=instance)
return render(request, "form.html", {"name":instance.name,'instance':instance,'form': form})
