Python decorators can be used in Django in order to avoid duplication of code in view functions. For instance, consider the following definition of a decorator that is then applied to a view function. This code has three bugs: 01: def fetch_author (view_func) : 02: 03: 04: def wrapper (request, *args, **kwargs) : try: author = Author.objects.get (id-request. GET ["author_id"]) view_func (request, author, *args, **kwargs) except Author. Does NotExist: return bad_request (request, Author. DoesNotExist) 05: 06: 07: 08: 09: 10: @fetch_author 11: def books_new (request) : 12: books = Book.objects.filter (authors_in=[author], year_gte="2015") 13: 14: 15: 16: 17: return view_func } context = { "title":"New books", "books" : books, return render (request, "books-recent.html", context) Identify the three lines which contain the three bugs: O Lines 5, 8 and 10 O Lines 7, 11 and 12 O Lines 5, 7 and 12 O Lines 5, 8 and 11 O Lines 10, 11 and 12 O Lines 7, 8 and 10

author = Author.objects.get(id=request. GET ["author_id"])
view_func(request, author, *args, **kwargs)
}
except Author. Does NotExist:
return bad_request (request, Author. Does NotExist)
return view_func
books = Book.objects.filter (authors_in= [author], year_gte="2015")
context = {
"title": "New books",
"books" : books,
return render (request, "books-recent.html", context)
