Question

我在Django-Tastypie API上创建了自己的资源。我一直在实现一些休息操作，现在我想实现我的自定义分页器，它将根据url传递的“key”生成next / prev值。

问题是：如果我传递一个像“http：localhost：8000 / api / stats / list / nextpage /”这样的值，obj_get会自动调用，不要让我返回一个值列表，只有一个值

所以我希望obj_get返回多个值。我的api.py看起来像这样：

我的资源类：

class CountryCountResource(Resource):

   countryName= fields.CharField(attribute='countryName')
   countryCount = fields.FloatField(attribute='countryCount')

   class Meta:
       resource_name = 'country/list'
       object_class = dict2obj
       include_resource_uri = False
       authorization = DjangoAuthorization()
       authentication = BasicAuthentication()

   def detail_uri_kwargs(self, bundle_or_obj):
       kwargs = {}

       if isinstance(bundle_or_obj, Bundle):
           kwargs['pk'] = bundle_or_obj.obj.countryName
       else:
           kwargs['pk'] = bundle_or_obj.countryName

       return kwargs

   def obj_get_list(self, request=None, **kwargs):

       db = MySQLdb.connect(host='xxxxxx',user='xxx',passwd='xxx',db='xxx')
       cur = db.cursor()
       cur.execute("SELECT count(*) FROM users")
       total_users=cur.fetchall()
       for item in total_users:
           totalint=int(item[0])

       cur.execute("SELECT country,count(country) FROM users GROUP BY country ORDER BY    count(country) DESC LIMIT 0,10")

       #ordered tuple
       mylist=cur.fetchall()

       newlist=[]
       for i in mylist:
           auxd={}
           auxd['countryName']=str(i[0])
           res=int(i[1])/float(totalint)
           res="%.2f" % res
           auxd['countryCount']=res
           newlist.append(dict2obj(auxd))

       db.close()

       return newlist

   def obj_get(self, request=None, **kwargs):
       return newlist <<<<<<------- DONT WORK

有什么想法吗？

我强烈建议您默认使用或自定义任何ModelResource附带的分页器行为：http://django-tastypie.readthedocs.org/en/latest/paginator.html
