django-pgtrigger VS awesome-mysql

For Django there's https://github.com/Opus10/django-pgtrigger that makes it possible to define triggers right in your models, so you have everything in one place.

django-pgtrigger – Write Postgres triggers for your Django models

Note that have now ditched our post_save signal from the previous solution. As we pointed out, signals can easily be missed. Instead, we are using a Postgres trigger : defining the listener as it is above makes use of the django-pgtrigger library to write a Postgres trigger to our database, the job of which is to notify our channel whenever a Comment is inserted in to the database. Triggers are far more robust than signals for detecting database write events; application level triggers can easily be missed, whereas triggers will always be executed.
