Django Rest Framework AttributeError： 'レスポンス'オブジェクトに 'エンコーディング'属性がありません

Question

APIRequestFactoryの代わりにAPIClientクラスを使用して、新しく作成したビューセットで簡単なテストを実行しようとしていますが、

AttributeError: 'Response' object has no attribute 'encoding' 

私もAPIRequestFactoryを使用する場合は正常に動作しますが、私はTokenAuthenticationを使用していますので、私はAPIClientを必要としています。

これは、私がクライアントを使用していたコンテキストです：

api_client = APIClient() 
reversed_url = reverse('showcase:ajax:publisher-dashboard', kwargs={'pk': 1}) 
client_token = cm.Client.objects.get(first_name='Cliente 1', 
            last_name='Prueba Showcase').user.auth_token.key 
api_client.credentials(HTTP_AUTHORIZATION='Token ' + client_token) 

request = api_client.get(reversed_url, format='json') 
response = views.PubViewSet.as_view({'get': 'dashboard'})(request, pk=1) 

は結果が資格情報を提供し、settings.pyにTokenAuthを無効にすることなく同じです。

APIRequestFactoryを使用している場合、これらは、Responseオブジェクトの内容は以下のとおりです。

<Response status_code=200, "text/html; charset=utf-8"> 

_charset = {NoneType} None 
_closable_objects = {list} <class 'list'>: [] 
_container = {list} <class 'list'>: [b''] 
_content_type_for_repr = {str} ', "text/html; charset=utf-8"' 
_handler_class = {NoneType} None 
_headers = {dict} {'content-type': ('Content-Type', 'text/html; charset=utf-8')} 
_is_rendered = {bool} False 
_post_render_callbacks = {list} <class 'list'>: [] 
_reason_phrase = {NoneType} None 
_request = {NoneType} None 
charset = {str} 'utf-8' 
closed = {bool} False 
content = {str} 'Traceback (most recent call last):\n File "/home/ariel/.local/pycharm-2017.1.1/helpers/pydev/_pydevd_bundle/pydevd_resolver.py", line 197, in _getPyDictionary\n attr = getattr(var, n)\n File "/home/ariel/.virtualenvs/recrow-app/lib/python3.6/site-packag

reason_phrase = {str} 'OK' 
rendered_content = {str} 'Traceback (most recent call last):\n File "/home/ariel/.local/pycharm-2017.1.1/helpers/pydev/_pydevd_bundle/pydevd_resolver.py", line 197, in _getPyDictionary\n attr = getattr(var, n)\n File "/home/ariel/.virtualenvs/recrow-app/lib/python3.6/site-packag 
rendering_attrs = {list} <class 'list'>: ['template_name', 'context_data', '_post_render_callbacks'] 
status_code = {int} 200 
status_text = {str} 'OK' 
streaming = {bool} False 
template_name = {NoneType} None 
using = {NoneType} None 

そしてAPIClientが使用されます。

Answer 1

私はあなたがこのコードの行でエラーが発生していると思う：

request = api_client.get(reversed_url, format='json') 
response = views.PubViewSet.as_view({'get': 'dashboard'})(request, pk=1) 

api_client.getは既にHTTPResponseを返すので、iを渡す必要はありませんtをVewSetに要求します。代わりに、これを試してみてください：

response = api_client.get(reversed_url) 
assert response.status_code == 200
