问题

In Django/Python, how do I catch a specific mySQL error: 'IntegrityError':

try:
   cursor.execute(sql)
except IntegrityError:
    do_something

Not sure what I should import and from where.

回答1:

DId you try from django.db import IntegrityError? First result for me in Google btw. when searching for IntegrityError.

Here is a similar response . In summary

from django.db import IntegrityError
from django.shortcuts import render_to_response

try:
# code that produces error
except IntegrityError as e:
return render_to_response("template.html", {"message": e.message})
