15.He gave a situation and asked what i could like "If a db error has occured how will you manage the situation" ans:exception handling can be implementedTimes asked 1Official solution
Simpletry/except. Catch Exception not BaseException (SystemExit). IntegrityError 404 abort.
Exception handling. Types ValueError TypeError KeyError IntegrityError HTTPException.
Pehle 1-line definition, phir related MAD2 layer (Vue SFC / Flask route / models.py / tasks.py / Redis).
4-line formula: input kahan se aaya, auth/validation kaunsa, DB ya cache ya Celery, kya return.
Related mix mat karo — cache ≠ Celery, authentication ≠ authorization, v-if ≠ v-show, Beat ≠ Worker. Follow-up ke liye ek difference ready rakho.
Example
try: db.session.commit() except IntegrityError: db.session.rollback() return jsonify(msg='duplicate'), 400Project example: commit except rollback 400.
