PyDev displays undefined variable from import for 1 out of 2 vars

问题

Issue

I have the following structure:

home.py
logic/brains/databeam.py

Inside databeam.py I have:

engine  = create_engine(databaseSettings(), pool_size = 20, max_overflow = 0)
Session = sessionmaker(bind = engine)
session = Session()

boom = 'boom'

And in home.py:

from logic.brains.databeam import session, boom

print session
print session.query()
print boom

Everything works as intended, but PyDev on eclipse shows me this:

This works when...

Instead of using from logic.brains.databeam import session as session, boom as boom, I do this:

import logic.brains.databeam
session = logic.brains.databeam.session
boom    = logic.brains.databeam.boom

But this seems untidy, is there a better way to show PyDev that the import works?

A solution that I found to be reasonable is to suppress this type of error in PyDev altogether. I know this is not perfect, but far and away the best one I've come across.
