我有一个Python类，该类接受参数中的url并在新闻网站上启动搜寻器。
对象创建完成后，该对象将存储在Elasticsearch集群中。
我想创建一个方法，该方法接受Elasticsearch文档的输入，并从中创建一个对象。
class NewsArticle():
def __init__(self, url):
self.url = url
# Launch a crawler and fill in the other fields like author, date, ect ...
@classmethod
def from_elasticsearch(cls, elasticsearch_article):
document = elasticsearch_article['_source']
obj = cls(document['url'])
obj.url = document['url']
obj.author = document['author']
.
.
.
问题是，当我打电话时...
# response is my document from elasticsearch
res = NewsArticle.from_elasticsearch(response)
...该方法__init__将被调用并启动我的搜寻器。无论如何，它不会启动我的搜寻器或调用init方法吗？
简单if和默认参数如何crawl：
class NewsArticle():
def __init__(self, url, crawl=True):
self.url = url
if crawl:
# Launch a crawler and fill in the other fields like author, date, ect ...
@classmethod
def from_elasticsearch(cls, elasticsearch_article):
document = elasticsearch_article['_source']
obj = cls(document['url'], crawl=False)
obj.url = document['url']
obj.author = document['author']
