Django helpers
custom user_account_fetched signal
postgrestutils provides a custom signal called user_account_fetched which provides the current request and the account of the current user on login.
To use this feature (and you really should 99.9% of the time) configure your settings accordingly by specifying the columns you need from the account endpoint:
# settings.py
POSTGREST_UTILS_AUTOFETCH = 'person_id,email' # comma-separated stringWhen connecting to the signal you will have to provide a callback function. That function is a great place for your custom logic to fetch and store additional information your app frequently needs into the session. You can connect to it like so:
# apps.py
from django.apps import AppConfig
from postgrestutils.signals import user_account_fetched
from your_app.utils import your_callback_func
class YourAppConfig(AppConfig):
def ready(self, *args, **kwargs):
super().ready(*args, **kwargs)
user_account_fetched.connect(your_callback_func)Your callback function could look something like this:
# utils.py
from postgrestutils.client import pgrest_client
def your_callback_func(sender, **kwargs):
request = kwargs['request']
account = kwargs['account']
# fetching some addtional data your project needs frequently using the pgrest_client (person, memberships etc.)
# 'caching' that data in the session
request.session['account'] = account
request.session['person'] = person
request.session['memberships'] = membershipsFor more information on signals refer to the django docs. They are great. Really.
