如何得到一个顶点的边缘对象数据，在东方分贝使用python

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'} 

这里我要重新绑定out_': <pyorient.otypes.OrientBinaryObject object>使用python。当我尝试此代码debind对象这个错误出现

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]) 

希望它可以帮助
