Tastypie: How can I fill the resource without data

问题:

I want to grab some information from Foursquare , add some fields and return it via django-tastypie. UPDATE:

def obj_get_list(self, request=None, **kwargs):
    near = ''
    if 'near' in request.GET and request.GET['near']:
        near = request.GET['near']
    if 'q' in request.GET and request.GET['q']:
        q = request.GET['q']

    client = foursquare.Foursquare(client_id=settings.FSQ_CLIENT_ID, client_secret=settings.FSQ_CLIENT_SECRET)

    a = client.venues.search(params={'query': q, 'near' : near, 'categoryId' : '4d4b7105d754a06374d81259' })

    objects = []

    for venue in a['venues']:
        bundle = self.build_bundle(obj=venue, request=request)
        bundle = self.full_dehydrate(bundle)
        objects.append(bundle)

    return objects

Now I am getting:

{
  "meta": {
    "limit": 20,
    "next": "/api/v1/venue/?q=Borek&near=Kadikoy",
    "offset": 0,
    "previous": null,
    "total_count": 30
  },
  "objects": [
    {
      "resource_uri": ""
    },
    {
      "resource_uri": ""
    }]
}

There are 2 empty objects. What should I do in order to fill this resource?

回答1:

ModelResource is only suitable when you have ORM Model behind the resource. In other cases you should use Resource.

This subject is discussed in ModelResource description, mentioning when it is suitable and when it is not: http://django-tastypie.readthedocs.org/en/latest/resources.html#why-resource-vs-modelresource

Also there is a whole chapter in the documentation, aimed at providing the details on how to implement non-ORM data sources (in this case: external API): http://django-tastypie.readthedocs.org/en/latest/non_orm_data_sources.html
