python - page()接受1个位置参数，但给出了2个

我正在尝试为搜索功能设计一个api。搜索基于地名。我想要的是localhost:8000/api/v1/rent/Search/？format=json&q=“california”但我收到一个错误，我在下面附加了一个错误

{
  "error_message": "page() takes 1 positional argument but 2 were given",
  "traceback": "Traceback (most recent call last):\n\n  File \"/home/tushant/.virtualenvs/rent/lib/python3.4/site-packages/tastypie/resources.py\", line 211, in wrapper\n    response = callback(request, *args, **kwargs)\n\n  File \"/home/tushant/Projects/rentals-v2.1/rentals/api/api.py\", line 102, in get_search\n    page = paginator.page(int(request.GET.get('page', 1)))\n\nTypeError: page() takes 1 positional argument but 2 were given\n"
}

我的搜索api代码是

    from rentals.models import Rental,Gallery
    from django.core.paginator import InvalidPage
    from django.conf.urls import *
    from tastypie.paginator import Paginator
    from tastypie.exceptions import BadRequest
    from tastypie.resources import ModelResource
    from tastypie.utils import trailing_slash
    from haystack.query import SearchQuerySet
     class SearchResource(ModelResource):
        class Meta:
            queryset = Rental.objects.all()
            resource_name = 'rent'

    def prepend_urls(self):
        return [
            url(r"^(?P<resource_name>%s)/search%s$" % (self._meta.resource_name, trailing_slash()), self.wrap_view('get_search'), name="api_get_search"),
        ]

    def get_search(self, request, **kwargs):
        self.method_check(request, allowed=['get'])
        self.is_authenticated(request)
        self.throttle_check(request)

        # Do the query.
        sqs = SearchQuerySet().models(Rental).load_all().auto_query(request.GET.get('q', ''))
        paginator = Paginator(sqs, 20)

        try:
            page = paginator.page(int(request.GET.get('page', 1)))
        except InvalidPage:
            raise Http404("Sorry, no results on that page.")

        objects = []

        for result in page.object_list:
            bundle = self.build_bundle(obj=result.object, request=request)
            bundle = self.full_dehydrate(bundle)
            objects.append(bundle)

        object_list = {
            'objects': objects,
        }

        self.log_throttled_access(request)
        return self.create_response(request, object_list)

我的models.py是

class Rental(models.Model):
        city =  models.CharField(_("City"), max_length=255, blank=False,null=True,
            help_text=_("City of the rental space"))
        place =  models.CharField(_("Place"), max_length=255, blank=False,null=True,
            help_text=_("Place of the rental space"))

    class Gallery(models.Model):
        rental = models.ForeignKey('Rental', null=True, on_delete=models.CASCADE,verbose_name=_('Rental'), related_name="gallery")
        image = models.ImageField(blank=True,upload_to='upload/',null=True)

我错过了什么？

最佳答案

您使用的是一个tastypepaginator类，它根据传入的请求自动检测当前页面，而Django Paginator类要求您传入页面索引。
下面是带有相关注释的代码：https://github.com/django-tastypie/django-tastypie/blob/master/tastypie/paginator.py#L26
试试这个：

    paginator = Paginator(request.GET, sqs, limit=20)

    try:
        page = paginator.page()
    except InvalidPage:
        raise Http404("Sorry, no results on that page.")
