Why to use this package if there is django-migrations and South?

The differencies between Django migrations and ua2.patch are in purpose:

  • django-migrations primary purpose is to propogate changes you make to your models into your database
  • ua2.patch purpose is to create & maintain patches, written by big development team

This package could be used in parallel to existing django-migrations module, or it can completely replace the job done by migrations. You, as developer, decide where you should use one or another.

We are not going to replicate all migration features, the core idea of this package is to provide easy to use tool to create and maintain (SQL|Python|Shell) patches for big team of people, working in parallel on different branches.

Installation

    'ua2.patch',

Usage examples

Create SQL patch

./manage.py patch next
File .../patches/00002-johnsmith-014.sql has been created
    size: 0

Now, you can open & edit the file. Note: until file size is zero, it would not be applied, but will be treated as reserved patch for future use.

Create Python patch

./manage.py patch next -e py
File .../patches/00002-johnsmith-022.py has been created
    size: 0

Note: patch body should have function main() which returns True. If you don't return True, the system will run the patch and exit on this place, preventing other scripts to run.

Create Shell patch

./manage.py patch next -e sh
File .../patches/00003-johnsmith-022.sh has been created
    size: 0
