3. Do you have a minute? ! I’d like to talk to you about our Lord and Saviour
4. Django REST Framework Browsable API ! Authentication ! Serialization ! Docs & community
5. ..meanwhile in Django.. from django.http import JSONResponse from django.core import serializers ! ! def books_list(request): qs = Book.objects.all() return JSONResponse(qs.values()) ! ! def book_detail(request, book_id): book = get_object_or_404(Book, id=book_id) dct = serializers.serialize(‘python’, [book]) return JSONResponse(dct)
6. DjangoRestless from restless.views import Endpoint from restless.models import serialize ! class BookList(Endpoint): def get(self, request): return serialize(Book.objects.all()) ! class BookDetail(Endpoint): def get(self, request, book_id): book = get_object_or_404(Book, id=book_id) return serialize(book)
7. model views from restless.modelviews import * ! ! class BookList(ListEndpoint): model = Book ! class BookDetail(DetailEndpoint): model = Book
8. custom serialization from restless.models import serialize ! ! def my_ordinary_view(request): book = Book.objects.all() return serialize(book, fields=[ ‘title’, (‘author’, { fields=[‘name’, ‘address’]}), (‘publisher’, { fields=[‘name’, ‘address’]}), ‘summary’, (’n_comments’, lambda x: x.comments.Count())])
