Database migration helper, using South.
|
|
|
|
Usage:
|
|
|
|
- Install South using the method suitable for your platform
|
|
http://south.aeracode.org/docs/installation.html
|
|
|
|
- You need to have a database setup, either an old one or
|
|
a fresh one. If the latter, run manage.py syncdb as normal,
|
|
entering superuser info etc.
|
|
|
|
- Start this tool and use the 'initialize' option. South will
|
|
create a migration scheme for all Evennia components.
|
|
|
|
That's all you need to do until Evennia's database scheme changes,
|
|
something which is usually announced with the update. To update
|
|
your current database automatically, follow these steps:
|
|
|
|
- Run this tool
|
|
|
|
- Select the Update option.
|
|
|
|
That is all. :)
|
|
|
|
For more advanced migrations, there might be further instructions.

Evennia Database Migration Tool
|
|
|
|
You usually don't need to use this tool unless a new version of Evennia tells you that
|
|
the database scheme changed in some way, AND you don't want to reset your database.
|
|
This tool will help you to migrate an existing database without having to manually edit
|
|
your tables and fields to match the new scheme. For that to work you must have run this
|
|
tool *before* applying the changes however.
|
|
|
|
This is a simple wrapper on top of South, a Django database scheme migration tool.
|
|
If you want more control, you can call manage.py directly using the instructions
|
|
found at http://south.aeracode.org/docs.
|
|
|
|
NOTE: Evennia is still in Alpha - there is no guarantee that database changes will still
|
|
not be too advanced to handle with this simple tool, and it is too soon to talk
|
|
of supplying custom migration schemes to new versions.
|
|
|
|
Options:
|
|
|
|
i - Initialize an existing/fresh database with migration mappings (done once)
|
|
u - Update an initialized database to the changed scheme
|
|
q - Quit
