如何遍历 ponyorm 实体对象
how to iterate over ponyorm entity object
我正在使用 ponyORM 并查询 PeopleModel" 例如:
first_name = "avi"
sqlObject = select(p for p in PeopleModel if raw_sql('( lower(first_name) = lower($first_name))
sqlObject object return PeopleModel 列表符合预期,非常完美。
现在我想打印所有 PeopleModel 值,我希望类似的东西能工作:
for people_model_key,people_model_value in sqlObject.items():
print(people_model_value)
但是没用..
如何打印所有 people_model 值?
非常感谢,
select
函数的结果是一个查询对象:
first_name = "avi"
people = select(p for p in PeopleModel
if raw_sql('( lower(first_name) = lower($first_name))
它不是字典,所以它没有items
方法。如果你遍历它,你会得到对象。您可以通过常规方式访问对象属性:
for person in people:
print('name:', person.name)
print('age:', person.age)
如果要将对象转换为字典,可以使用to_dict
方法:
for person in people:
for key, value in person.to_dict().items():
print(key, value)
