David added the comment:
when I do anything like this:
import flask ...
class User......
.
.
.
try:
current_user
except NameError:
global current_user
current_user = User(request.form['parameter1'], request.form['parameter2'],
'')
I get the error that current_user_user was 'used' before the global
declaration. The try ... except ... is so when the user enters this route /
function the first time, a class instance is instantiated, but if they return
the second time, the existing class instance is updated in lines of code
downstream rather than declared again with the same name, and therefore
overwritten.
