python - 如何使用python获取orient db中顶点的边缘对象数据

Question

import pyorient

# create connection 
client = pyorient.OrientDB("localhost", 2424) 

# open databse 
client.db_open( "Test", "admin", "admin" )

requiredObj = client.command(' select from chat where app_cat=appCategory and module=module and type=type and prob_cat=problemCategory  ')

print requiredObj[0]

输出:

#Output
{'@Chat':{'prob_cat': 'PERFORMANCE', 'type': 'NON FUNCTIONAL', 'module': 'app', 'out_': <pyorient.otypes.OrientBinaryObject object at 0x10d1d6c10>, 'app_cat': 'RETAIL', 'issue': 'Non Capture of Data'},'version':7,'rid':'#22:0'}

这里我想重新绑定(bind) out_': <pyorient.otypes.OrientBinaryObject object>使用Python。当我尝试使用此代码来解除对象绑定(bind)时，会出现此错误

print requiredObj[0].out_[0]

TypeError: 'OrientBinaryObject' object does not support indexing

Answer 1

你可以使用

requiredObj = client.command(' select expand(out()[0]) from chat where app_cat=appCategory and module=module and type=type and prob_cat=problemCategory  ')

print(requiredObj[0])
