Django initial form values from db query in views

I'm trying to set initial values in form for editing within views. For example i want to edit book that is allready stored in database setting initial values from database query. Is it possible in django ? For instance:

views.py:

from .models import Book
from .forms import BookForm

def edit_book(request,book_id):
    query_book=Book.objects.get(pk=book_id)
    Book_form_to_edit =BookForm(initial=query_book)
    context={
    'book_form':Book_form_to_edit,
    }
    return render(request,'edit_book.html',context)

Thank you in advance.

Yess, it is possible try referring the code below. I have edited your code so you will grab some idea on it.

from .models import Book
from .forms import BookForm

def edit_book(request,book_id):
    query_book=Book.objects.get(pk=book_id)
    Book_form_to_edit =BookForm(request.POST, instance=query_book)

    if Book_form_to_edit.is_valid():
      Book_form_to_edit.save()

    context={
      'book_form':Book_form_to_edit,
    }
    return render(request,'edit_book.html',context)

and in url.py make sure to get the book_id

path('<int:book_id>/Edit/', views.edit_view, name='edit')
