Using pyodata, how do I list all available properties of a queried Entity?
问题
我想要动态列出使用PyOData包从odata实体中获取所有可用属性的方法。
以下是我想要做的事情：
service = pyodata.Client(SERVICE_URL, session)positions = service.entity_sets.TRLPositionSet.get_entities().select('Prop1,Prop2').execute()for p in positions:# 如何实现下面的get_properties函数？properties = get_properties(p)for prop in properties:print(prop.name, getattr(p, prop.name))
我该如何实现get_properties(p)函数以使其返回一个列表['Prop1', 'Prop2']？

Here is what I'd like to do:
service = pyodata.Client(SERVICE_URL, session)positions = service.entity_sets.TRLPositionSet.get_entities().select('Prop1,Prop2').execute()for p in positions:# how to implement get_properties below?properties = get_properties(p)for prop in properties:print(prop.name, getattr(p, prop.name)
How would I implement the get_properties(p) function to make it return a list ['Prop1', 'Prop2']?

翻译结果如下：
看看这里：https://github.com/SAP/python-pyodata/issues/53#issuecomment-533261246for es in client.schema.entity_sets:print(es.name)properties = es.entity_type.properties()for prop in es.entity_type.key_properties:print(f' K {prop.name}({prop.type.name})')properties.remove(prop)for prop in properties:print(f' + {prop.name}({prop.type.name})')for prop in es.entity_type.nav_properties:print(f' + {prop.name}({prop.to_role.entity_type_name})')在我的情况下，我必须使用`es._entity_type`
请注意，我已经将代码中的 "proprties" 更正为 "properties"，并将 "key_proprties" 更正为 "key_properties"，以及 "nav_proprties" 更正为 "nav_properties"，以匹配正确的Python语法。

Take a look here:
https://github.com/SAP/python-pyodata/issues/53#issuecomment-533261246
for es in client.schema.entity_sets:
print(es.name)
proprties = es.entity_type.proprties()for prop in es.entity_type.key_proprties:print(f' K {prop.name}({prop.typ.name})')proprties.remove(prop)for prop in proprties:print(f' + {prop.name}({prop.typ.name})')for prop in es.entity_type.nav_proprties:print(f' + {prop.name}({prop.to_role.entity_type_name})')
In my case I had to use es._entity_type
