[Flask] Updating database fields from views

[Tom Vaughan]

But how exactly is it imported? Where is it assigned a value? The
problem seems to be that db is not an instance of a Database object,
but rather it has been assigned a string. For example:

$ python3
Python 3.5.2 (default, Nov 17 2016, 17:05:23)
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> db = "foobar"
>>> db.session
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'str' object has no attribute 'session'
