How to use tastypie for showing contents of model based on client_id in oauth 2.0?

Question

I have a problem where I want to filter model resourse based on a field and show that particular queryset to the requesting client_id.

I am using tastypie v0.10.0 with django 1.6.5 and swagger UI for documentation.

In Example model I have stored information related to all clients and want to show the data belongs to the particular client based on client id. I have filters fields in Example model based on which I can create queryset for particular client.

class Resource(ModelResource):
    class Meta:
        queryset = Example.objects.all()
        resource_name = 'example'
        authorization = DjangoAuthorization()
        detail_allowed_methods = ['get',]
        authentication = OAuth20Authentication()

Please suggest me the best way to implement the above scenario. Thanks in advance.

Here is the solution I came out with.

import provider.oauth2
from provider.oauth2.models import AccessToken


class Resource(ModelResource):
    # 
    class Meta:
        queryset = Example.objects.all()
        resource_name = 'example'
        authorization = DjangoAuthorization()
        detail_allowed_methods = ['get',]
        always_return_data = True
        authentication = OAuth20Authentication()

        key = bundle.request.GET.get('oauth_consumer_key')
        if not key:
            key = bundle.request.POST.get('oauth_consumer_key')
        if not key:
            auth_header_value = bundle.request.META.get('HTTP_AUTHORIZATION')
            if auth_header_value:
               key = auth_header_value.split(' ')[1]

        token = verify_access_token(key)
        >>>>> token.user this contains username
        >>>> come out with the proper conditions through which you can create queryset
        queryset = Example.objects.filter(field=condition)
        return queryset
