pretalx comes with commands that you can execute from the command line. Run them in the same environment you installed pretalx in. If you followed the installation guide, you can run the following as your pretalx user:
python -m pretalx <command> [<flags>] [<options>]
python -m pretalx migrate¶
migrate command updates the database tables to conform to what pretalx
expects. Please execute it once upon installation and then on every update. As
migrate touches the database, you should have a backup of the state before
the command run.
migrate if pretalx has no pending database changes is harmless. It
will result in no changes to the database.
If migrations touch upon large populated tables, they may run for some time. The release notes will include a warning if an upgrade can trigger this behaviour.
python -m pretalx showmigrations¶
If you ran into trouble during
showmigrations. It will
show you the current state of all pretalx migrations. It may be useful debug
output to include in bug reports about database problems.
python -m pretalx clearsessions¶
This command will remove old and unusable sessions from the database. We recommend that you run it about once a month to keep your database at a reasonable size.
python -m pretalx shell or
python -m pretalx shell_plus¶
shell command opens a Python shell with the pretalx configuration and
environment. You can use it to import pretalx modules and execute methods. For
a better environment, install
shell_plus instead. This shell gives you tab completion, and a
range of useful initial imports.
python -m pretalx print_settings¶
If other debugging fails, install the
django_extensions package. Run
print_settings to receive full settings output. The output will contain
passwords, so sanitise it before pasting it anywhere.
If you don’t want to install a library for debugging, you can run these commands instead:
python -m pretalx shell >>> from django.conf import settings >>> from pprint import pprint >>> pprint(settings.__dict__)
The warning about included passwords and secrets in the output goes for this version as well.
Core pretalx commands¶
