如何在 Elixir 中保存模型
我已经使用 Django 模型创建了一个数据库，现在我正在使用 SQLAlchemy 和 Elixir 访问该数据库。查询有效，我可以完美地从数据库中提取项目，但是当我编辑它们并尝试保存它们时，它会抛出以下异常：
>>> p = Problem.query.first()
>>> p
<Problem('Test Problem', 'This is a test problem so the database has something in it', 'SBMT')>
>>> p.name
u'Test Problem'
>>> p.name = "Test_Problem"
>>> p.save()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.7/site-packages/elixir/entity.py", line 1116, in save
return self._global_session.save(self, *args, **kwargs)
AttributeError: 'Session' object has no attribute 'save'
我做错了什么？我是否错过了设置中阻止我将内容保存到数据库的关键部分，或者是我的 elixir 和 SQLAlchemy 版本有问题？
我已经运行 setup_all() 并且 metadata.bind 已全部设置，因此我可以查询数据库。
I've got a database created using Django models which I'm now accessing using SQLAlchemy and Elixir. The querying works and I can pull items out of the database perfectly happily but when I edit them and try to save them it throws the following exception:
>>> p = Problem.query.first()
>>> p
<Problem('Test Problem', 'This is a test problem so the database has something in it', 'SBMT')>
>>> p.name
u'Test Problem'
>>> p.name = "Test_Problem"
>>> p.save()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.7/site-packages/elixir/entity.py", line 1116, in save
return self._global_session.save(self, *args, **kwargs)
AttributeError: 'Session' object has no attribute 'save'
What am I doing wrong? Have I missed a crucial part of the set up that is preventing me from saving things to the database or is it a problem with my versions of elixir and SQLAlchemy?
I've already run setup_all() and the metadata.bind is all set, hence I can query the database.

我不是 Elixir 专家，但从文档来看，它似乎使用了一种称为全局会话的东西。
要将更改保存到数据库，您需要执行
session.commit()，没有像 Django 中那样的save()方法。I'm no Elixir expert, but from the documentation it looks like it uses something called a global session.
To save the changes to the database, you do a
session.commit(), there's nosave()method like in Django.
