Python的前夜 - 更新记录,如果存在,否则插入
我使用的是默认的例子..Python的前夜 - 更新记录,如果存在,否则插入
run.py
from eve import Eve
app = Eve(template_folder=tmpl_dir)
if __name__ == '__main__':
app.run(debug=True)
settings.py
RESOURCE_METHODS = ['GET', 'POST', 'DELETE']
ITEM_METHODS = ['GET', 'PUT', 'PATCH', 'DELETE']
CACHE_CONTROL = 'max-age=20'
CACHE_EXPIRES = 20
IF_MATCH = False
people = {
# 'title' tag used in item links.
'item_title': 'person',
'item_url': 'regex("[a-zA-Z0-9.]+")',
'item_lookup': True,
'item_lookup_field': 'firstname',
'additional_lookup': {
'url': 'regex("[\w]+")',
'field': 'firstname'
},
'schema': {
'firstname': {
'type': 'string',
#'required': True,
'unique': True,
},
'age': {
'type': 'integer'
}
}
}
DOMAIN = {
'people': people
}
现在,我可以很容易地创建新条目
curl -X POST -F "firstname=john" -F "age=24" "http://127.0.0.1:5000/people"
输出
{"_updated": "Fri, 02 Dec 2016 10:12:58 GMT", "_created": "Fri, 02 Dec 2016 10:12:58 GMT", "_status": "OK", "_id": "5841492a10cf9320678bef65", "_links": {"self": {"href": "people/5841492a10cf9320678bef65", "title": "person"}}}
我现在可以轻松地发送一个卷曲的请求
curl -X GET "http://127.0.0.1:5000/people/john"
,并获得记录以来姓是我额外的查找
输出
{"_updated": "Fri, 02 Dec 2016 10:12:58 GMT", "firstname": "john", "age": 24, "_links": {"self": {"href": "people/5841492a10cf9320678bef65", "title": "person"}, "collection": {"href": "people", "title": "people"}, "parent": {"href": "/", "title": "home"}}, "_created": "Fri, 02 Dec 2016 10:12:58 GMT", "_id": "5841492a10cf9320678bef65"}
我现在还可以修补文件,改年龄的,
curl -X PATCH -F "age=32" "http://127.0.0.1:5000/people/john"
输出
{"_updated": "Fri, 02 Dec 2016 10:15:56 GMT", "_created": "Fri, 02 Dec 2016 10:12:58 GMT", "_status": "OK", "_id": "5841492a10cf9320678bef65", "_links": {"self": {"href": "people/5841492a10cf9320678bef65", "title": "person"}}}
我的问题:
以上PATCH只会当记录存在时工作,在那里一种方式,我可以发送PUT或PATCH请求与数据,让我们决定要么创建新的条目或修改,如果该条目已经存在?
希望我的问题是不够清楚
您设置了additional_lookup
额外的端点是只读的:
Besides the standard item endpoint which defaults to
/<resource>/<ID_FIELD_value>
, you can optionally define a secondary, read-only, endpoint like/<resource>/<person_name>
.
在你的设置,我觉得你并不需要设置additional_lookup
可言,因为它只是重新定义了item_lookup_field
(它设置了您的读/写端点)。
删除additional_lookup,并发送一个PUT请求到/
做了一个点安装升级前夕,一切开始工作,如记录在网站上。基本上我显然是在版本0.5.3。我想知道为什么? –
http://python-eve.org/features.html#event-hooks – metmirr
UPSERT_ON_PUT功能已存在,但似乎无法正常工作。我错过了什么? –
你会得到同样的错误吗?:'id = lookup [resource_def ['id_field']] KeyError:'_id' ' – metmirr
