问题描述

我正在尝试设计用于搜索功能的api.搜索基于地名.我想要的是localhost:8000/api/v1/rent/search/?format = json& q ="california"，但是我收到了一个错误，该错误已在下面附上

I am trying to design an api for search functionality. Search is based on place name.What i want is localhost:8000/api/v1/rent/search/?format=json&q="california" but i am getting an error which i have attached below

{
  "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)

我想念什么?

推荐答案

您正在使用Tastypie Paginator类，该类根据传递给它的请求自动检测当前页面，这与Django Paginator类不同，该类需要您执行以下操作:传递页面索引.

You're using a Tastypie Paginator class, which automatically detects the current page based on the requests passed in to it, unlike the Django Paginator class which requires you to pass in the page index.

以下是带有相关注释的代码: https ://github.com/django-tastypie/django-tastypie/blob/master/tastypie/paginator.py#L26

Here's the code with relevant comments: https://github.com/django-tastypie/django-tastypie/blob/master/tastypie/paginator.py#L26

尝试一下:

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

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