hello, AppConfig could provide hooks, but it'd indeed be already quite late in the setup process : settings are already loaded, logging already configured, script prefix already set, and just accessing AppConfig could already trigger the import of advanced submodules (models etc.), which could break the early setup.
I guess an environment variable, or a naming convention, could allow early hooks similar to those of Gunicorn for example, and unrelated to installed apps. regards, Pascal Chambon On Tuesday, July 2, 2019 at 8:40:04 PM UTC+2, Christian González wrote: > > > Am 01.07.19 um 23:24 schrieb Pkl: > > > > Regarding django.setup() tweakability, the generic need is simply to > > have a hook, somewhere for users to put early init code, regardless of > > the way django is launched.
