我尝试使用django-haystack
在我的应用中添加基于elasticsearch
的搜索。我使用django-rest-framework
来构建API。以下是我的索引:
class ArtistIndex(indexes.SearchIndex, indexes.Indexable):
text = indexes.CharField(document=True, model_attr='name')
def get_model(self):
return Artist
这是我的观点:
def search(request):
q = request.GET.get('q', '')
if q is '':
return Response(status=status.HTTP_400_BAD_REQUEST)
all_results = SearchQuerySet().models(Artist).filter(content=Clean(q))
serializer = ArtistSerializer(all_results, many=True)
print serializer.data
return Response(status=status.HTTP_200_OK)
我的序列化器:
class ArtistSerializer(serializers.ModelSerializer):
class Meta:
model = Artist
fields = (
'name',
'type',
'gender',
'begin_life',
'end_life',
)
但是,当我点击端点时,print
语句会打印出类似这样的内容:
[{'name': None, 'type': None, 'gender': None, 'begin_life': None, 'end_life': None}, {'name': None, 'type': None, 'gender': None, 'begin_life': None, 'end_life': None}, {'name': None, 'type': None, 'gender': None, 'begin_life': None, 'end_life': None}, {'name': None, 'type': None, 'gender': None, 'begin_life': None, 'end_life': None}, {'name': None, 'type': None, 'gender': None, 'begin_life': None, 'end_life': None}]
有人可以告诉我我做错了什么吗?
感谢。
答案 0 :(得分:3)
我找到了更好的序列化数据的方法。我现在正在使用它:
from django.core import serializers
-- snippet --
def search(request):
q = request.GET.get('q', '')
if q is '':
return Response(status=status.HTTP_400_BAD_REQUEST)
all_results = SearchQuerySet().filter(content=Clean(q))
serializer = serializers.serialize("json", [q.object for q in all_results])
print serializer
return Response(status=status.HTTP_200_OK)
现在,我可以搜索多个模型而无需担心序列化数据:)
结果数据如下:
{
"fields": {
"name": "Megadeth",
"end_life": "",
"gid": "a9044915-8be3-4c7e-b11f-9e2d2ea0a91e",
"gender": "",
"type": "2",
"begin_life": "1983-6-"
},
"model": "InQusic.artist",
"pk": 975773
}
所以,现在我可以在我的客户端区分结果。
