django - 如何将详细信息对象传递给tastypie 中的自定义授权？

Question

在 Tastypie 授权期间，如何访问请求中正在访问的详细端点对象？

我注意到 docs 中被覆盖的方法之一有一个对象参数——我该如何设置？

Answer 1

在分行烫发中，

https://github.com/toastdriven/django-tastypie/blob/perms/tastypie/authorization.py

类授权有一组方法，例如:

def read_detail(self, object_list, bundle):
    """
    Returns either ``True`` if the user is allowed to read the object in
    question or throw ``Unauthorized`` if they are not.
    Returns ``True`` by default.
    """
    return True

这里可以尝试通过 访问obj bundle.obj

如果你不能使用 perms 分支，我建议你这样:

class MyBaseAuth(Authorization):
    def get_object(self, request):
        try:
            pk = resolve(request.path)[2]['pk']
        except IndexError, KeyError:
            object = None # or raise Exception('Wrong URI')
        else:
            try:
                object = self.resource_meta.object_class.objects.get(pk=pk)
            except self.resource_meta.DoesNotExist:
                object = None
        return object


class FooResourceAuthorization(MyBaseAuth):
    def is_authorized(self, request, object=None):
        if request.method in ('GET', 'POST'):
            return True
        elif request.method == 'DELETE':
            object = self.get_object(request)
            if object.profile = request.user.profile:
                return True
        return False
