Django migration linter

Detect backward incompatible migrations for your django project. All in one file.

Usage

python migration_linter.py DJANGO_PROJECT_FOLDER [GIT_COMMIT_ID] [--ignore-name-contains=IGNORE_NAME_CONTAINS] [--include-apps INCLUDE_APPS [INCLUDE_APPS ...] | --exclude-apps EXCLUDE_APPS [EXCLUDE_APPS ...]]

• DJANGO_PROJECT_FOLDER - an absolute or relative path to the django project.
• GIT_COMMIT_ID - if specified, only migrations since this commit will be taken into account. If not specified, the initial repo commit will be used.
• --ignore-name-contains IGNORE_NAME_CONTAINS- ignore migrations containing this name
• --include-apps INCLUDE_APPS [INCLUDE_APPS ...] - check only migrations that are in the specified django apps
• --exclude-apps EXCLUDE_APPS [EXCLUDE_APPS ...] - ignore migrations that are in the specified django apps

Requirements

Needed software (in PATH):

• python (only tested on python2.7 (yet))
• git
• UNIX command line tools like tail

The linter will try to detect whether if the project is a django project and is versioned with git.

Tests

Launch the tests with: python -m unittest test_migration_linter

More test are to be written.

Improvements

• Add an appropriate license
• More tests (always!)
• Detect data migration (not only scheme migrations)
• Detection dependent on specified database (mysql, postgresql, ...)
