DELETE requests

Finally, we have the DELETE request, which is the simplest of the four supported methods. The main difference with the delete method is that it returns no content, which is the accepted standard with DELETE requests:

class PostApi(Resource):
    @marshal_with(post_fields)
    def get(self, post_id=None):
        …

    def post(self, post_id=None):
        …

    def put(self, post_id=None):
        …

    def delete(self, post_id=None):
        if not post_id:
            abort(400)

        post = Post.query.get(post_id)
        if not post:
            abort(404)

        args = post_delete_parser.parse_args(strict=True)
        user = verify_auth_token(args['token'])
        if user != post.user:
            abort(403)

        db.session.delete(post)
        db.session.commit()
        return "", 204

Again, we can test with:

$ curl -X DELETE\
-d "token=<the token>"\
http://localhost:5000/api/post/102 ...
