1. 環(huán)境
- windows 10呼奢；
- elasticsearch 7.8.0握础；
- Django
2. 問題
- 使用 elasticsearch + Django 搭建搜索引擎悴品，在獲取 suggest 時(shí)遇到 AttributeError: 'Response' object has no attribute 'my_suggest' 報(bào)錯(cuò)，
- 問題代碼如下：
from SEARCH.models import ArticleType # 注意：ArticleType 是在另一個(gè)文件單獨(dú)定義的孤澎！
from django.http import HttpResponse
from elasticsearch import Elasticsearch
from datetime import datetime
client = Elasticsearch(hosts=["127.0.0.1"])
s = ArticleType.search()
s = s.suggest(
'my_suggest',
"xx",
completion={
"field": "suggest",
"fuzzy": {
"fuzziness": 2
},
"size": 10
}
)
suggestions = s.execute()
- 報(bào)錯(cuò)如下：
KeyError: 'my_suggest'
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "C:\Users\Administrator\AppData\Local\Programs\Python\Python37\lib\site-packages\django\core\handlers\exception.py", line 34, in inner

AttributeError: 'Response' object has no attribute 'my_suggest'
3. 解決
- 原因
elasticsearch 版本更新導(dǎo)致用法變更，問題代碼是舊的寫法型将，需要將 s.execute_suggest() 變更為 s.execute().to_dict()荐虐； - 更新代碼
from django.http import HttpResponse
from elasticsearch import Elasticsearch
from datetime import datetime
client = Elasticsearch(hosts=["127.0.0.1"])
s = ArticleType.search()
s = s.suggest(
'my_suggest',
"九州",
completion={
"field": "suggest",
"fuzzy": {
"fuzziness": 2
},
"size": 10
}
)
# 調(diào)用 execute_suggest 方法
# suggestions = s.execute()
suggestions = s.execute().to_dict() # 此處將 s.execute_suggest() 變更為 s.execute().to_dict()
print("#" * 50)
print(suggestions)
print("#" * 50)
- 打印結(jié)果如下缚俏，問題解決：
