Question

if i’m using django, and a user submits, say, a comment to my website – what is the best way (or what ways are there?) to programatically “alert” that a url has been submitted, and then do something to that url?

Either “fix” it so it isn’t clickable, or “flag” it so i review the comment before approving, or emailing me saying “someone submitted a comment” – or, you know what, provide a hook so i can do something?

cheers!

Answer 1

1. Connect a function to post_save signal

2. For every value in instance.__dict__, check for presence of a url

3. If a url is present, send an email or do what you want

For example:

from django.db.models import signals

def check_for_url(sender, instance, created, kwargs**):
    for value in instance.__dict__.values():
        if 'http://' in value:
            # do want you want
post_save.connect(check_for_url)

Since your question isn’t precise, that should give you some starters, you should of course refine it according to your specific needs.
