couchdb-python指定自己的_id失败

Question

如何在couchdb-python（0.9）中定义自己的_id，因为当我尝试'_id': i[5]时，我收到以下错误消息？

$ python test3.py 
828288 
Traceback (most recent call last): 
    File "test3.py", line 42, in <module> 
    db.save(doc) 
    File "/home/mictadlo/.virtualenvs/unisnp/lib/python2.7/site-packages/couchdb/client.py", line 415, in save 
    func = _doc_resource(self.resource, doc['_id']).put_json 
    File "/home/mictadlo/.virtualenvs/unisnp/lib/python2.7/site-packages/couchdb/client.py", line 954, in _doc_resource 
    if doc_id[:1] == '_': 
TypeError: 'int' object has no attribute '__getitem__' 

下面是这是造成上述错误的脚本：

from couchdb.mapping import Document, TextField, IntegerField, Mapping 
from couchdb.mapping import DictField, ViewField, BooleanField, ListField 
from couchdb import Server 

# $ sudo systemctl start couchdb 
# http://localhost:5984/_utils/ 

server = Server() 
db = server.create("test") 

r = [["Test", "A", "B01", 828288, 1, 7, 'C', 5], 
    ["Test", "A", "B01", 828288, 1, 7, 'T', 6], 
    ["Test", "A", "B01", 171878, 3, 8, 'C', 5], 
    ["Test", "A", "B01", 171878, 3, 8, 'T', 6], 
    ["Test", "A", "B01", 871963, 3, 9, 'A', 5], 
    ["Test", "A", "B01", 871963, 3, 9, 'G', 6], 
    ["Test", "A", "B01", 1932523, 1, 10, 'T', 4], 
    ["Test", "A", "B01", 1932523, 1, 10, 'A', 5], 
    ["Test", "A", "B01", 1932523, 1, 10, 'X', 6], 
    ["Test", "A", "B01", 667214, 1, 14, 'T', 4], 
    ["Test", "A", "B01", 667214, 1, 14, 'G', 5], 
    ["Test", "A", "B01", 667214, 1, 14, 'G', 6]] 


for i in r: 
    print i[3] 

    doc = { 
     'type': i[0], 
     'name': i[1], 
     'sub_name': i[2], 
     'pos': i[3], 
     's_type': i[4], 
     '_id': i[5], 
     'chr':[] 
    } 
    doc['chr'].append({ 
     "letter":i[6], 
     "no":i[7] 
    }) 

    db.save(doc)

该公司预计_id是一个字符串，你传递一个int类型的。错误是由以下行引起的：

if doc_id[:1] == '_': 

因为脚本正在尝试切分int对象。

所以将其更改为字符串类型：

... 
... 
'_id': str(i[5]), 
...
