Flask - Ecosystem and Patterns

You wrote this repository method:

def add_user(self, user):
    db.session.add(user)
    db.session.commit

What is the error here?

AMissing parentheses after commit method call

Bdb.session.add should be db.add

Cuser parameter should be a dictionary, not an object

Dcommit should be called before add

Step-by-Step Solution

Solution:

Step 1: Check method calls on db.session
The commit method must be called with parentheses: commit().
Step 2: Identify the missing parentheses error
Without parentheses, commit is just a reference, so changes are not saved.
Final Answer:
Missing parentheses after commit method call -> Option A
Quick Check:
commit() needs parentheses to execute [OK]

Quick Trick: Always call commit() with parentheses [OK]
