由于这个原因，我一直在拉头发。在我的案例中，ModelField似乎是一个不错的选择，但我似乎无法让它发挥作用。我正在为一个项目开发一个搜索引擎。
serializers.py
class FullSearchSerializer(serializers.Serializer):
profiles = serializers.ModelField(model_field=Profiles())
cv = serializers.ModelField(model_field=CV())
我得到了这个奇妙的错误：
'Profiles' object has no attribute '_get_val_from_obj'
我这样做的原因是因为我在序列化之前获取，列出和分页了几个模型。因此：（views.py）
result_list = []
for target in targets:
result = targets[target]['model'].objects.select_related().filter(reduce(operator.or_, targets[target]['query_list']) & targets[target]['extra_query'])
if result:
result_list.append(result)
print result_list
results = list(
sorted(
chain(*result_list),
key = lambda objects: objects.id,
)
)
print results
page = request.QUERY_PARAMS.get('page')
paginated_result = paginate(results, page)
serializer_context = {'request': request}
serialized = PaginatedSearchSerializer(paginated_result, context=serializer_context)
print serialized.data
return JSONResponse(serialized.data, status=status.HTTP_200_OK)
return JSONResponse({'message': 'No results'})
＆＃34;目标[靶标] [＆＃39;模型＆＃39;]＆＃34;等等来自我循环的字典，获得正确的模型，序列化器等等。由于我正在创建一个能够搜索所有内容的函数，而不指定目标，我需要一个可以处理它的序列化程序。
