6.0.0

Feature:

  • Breaking change: Handle custom Django app label when gathering migrations from git reference. (#262) This means that, an app that was previously referenced by its folder name, will now be referenced by its Django app label.

Miscellaneous:

  • Add py.typed file (#303)
  • Add support for Django 5.2 (#304)

5.2.0

Feature:

  • Allow ignoring all initial migrations, with --ignore-initial-migrations

Bug:

  • Don't detect an index creation during a transaction with an exclusive lock, when the table is being created (#264)

Miscellaneous:

  • Add support for Python 3.13
  • Add support for Django 5.1
  • Drop support for Python 3.7 and 3.8
  • Mark md5 hashing as not used for security

5.1.0

Feature:

  • Support Django 5.0 db_default attribute (issue #275)
  • Allow ignoring the failures of sqlmigrate commands, with --ignore-sqlmigrate-errors option (issue #274)

Bug:

  • Don't detect 'IS NOT NULL' as backward incompatible changes (issue #263)
  • Don't consider UNIQUE INDEX creation as making a column not nullable

Miscellaneous:

  • Migrated from setup.py and setup.cfg to pyproject.toml
  • Add support for Python 3.12
  • Add support for Django 5.0
  • Avoid git command injections
  • Remove Codecov integration

5.0.0

  • Breaking change: stop silently ignoring when the internal sqlmigrate call fails and the linter cannot analyse the migration. Instead, the linter crashes and lets the sqlmigrate error raise, in order to avoid letting a problematic migration pass. One common reason for such an error is the SQL generation which requires the database to be actually migrated in order to fetch actual constraint names from it. The crash is a sign to double-check the migration. But if you are certain the migration is safe, you can ignore it (issue #209)

Features:

  • Fixed RunPython model import check when using a through object like MyModel.many_to_many.through.objects.filter(...) (issue #218)
  • Mark the IgnoreMigration operation as elidable=True
  • Handle functools.partial functions in RunPython data migrations
  • Add a new check, CREATE_INDEX_EXCLUSIVE to detect index creation while an exclusive lock is held

Bug:

  • Don't detect not nullable field on partial index creation (issue #250)

Miscellaneous:

  • Add support for Python 3.11
  • Add support for Django 4.1
  • Add support for Django 4.2
  • Drop support for Django 2.2
  • Internally rename "migration tests" to "migration checks"
  • Add dataclasses internally instead of custom dicts
  • Use pre-commit hooks for linting
  • Add mypy and ruff usages

4.1.0

  • Allow configuring logging for makemigrations command and unify behaviour with lintmigrations (issue #207)
  • Adapt --warnings-as-errors option to allow selecting some migration tests only (issue #201)
  • Add sql_analyser option to makemigrations in order to specify the SQL analyser to use (issue #208)
  • Make project_root_path and verbosity configurable from other setting source (issue #203)

4.0.0

  • Drop support for Django 1.11, 2.0, 2.1, 3.0 and 3.1
  • Add support for Django 4.0
  • Fix index creation detection when table is being created in the transaction (issue #178)
  • Handle unique index creation as adding a unique constraint (issue #183)
  • Allow any option to be set/unset in config file (issue #167)
  • Allow using Django settings for any option to be set/unset (issue #198)
  • Raise when unsupported database vendor, allow passing an option to select SQL analyser (issue #138 and #169)

3.0.1

Fixed bug:

  • Setting a field as NOT NULL without default passed the linter.

3.0.0

Breaking API change on lintmigrations command:

  • the positional argument GIT_COMMIT_ID becomes an optional argument with the named parameter --git-commit-id [GIT_COMMIT_ID]
  • the lintmigrations command takes now two positional arguments: lintmigrations [app_label] [migration_name]

New features:

2.5.3

  • Stop packaging the 'tests' module into the release wheel file
  • Add Django 3.2 support

2.5.2

  • Remove toml support for config files

2.5.1

  • Remove .editorconfig from default config file
  • Allow utf-8 encoding in config files

2.5.0

Renamed lint checks:

  • REVERSIBLE_DATA_MIGRATION -> RUNPYTHON_REVERSIBLE
  • NAMING_CONVENTION_RUNPYTHON_ARGS -> RUNPYTHON_ARGS_NAMING_CONVENTION
  • DATA_MIGRATION_MODEL_IMPORT -> RUNPYTHON_MODEL_IMPORT
  • DATA_MIGRATION_MODEL_VARIABLE_NAME -> RUNPYTHON_MODEL_VARIABLE_NAME
  • REVERSIBLE_RUNSQL_DATA_MIGRATION -> RUNSQL_REVERSIBLE

Features/fixes:

  • Make data migration model import error less strict (issue #121)
  • Add warning detection on RunPython call when model variable name is not the same as model class name
  • Run checks on RunSQL migration operations
  • Rename the RunPython data migration lint checks for improved consistency
  • Refactor and commonise the loggers, so that all modules the django_migration_linter logger
  • Allow using configuration file for linter options
  • Add option --include-name and --include-name-contains to only include migration with a certain name

Others:

  • Switched from Travis CI to GitHub Actions for tests
  • Apply isort to the project

2.4.1

  • Add Django 3.1 support
  • Upgrade linter versions of flake8 and black to the latest

2.4.0

  • Add possibility to lint newly generated migrations through the makemigrations command. You can activate it through the --lint command option, or by default with the MIGRATION_LINTER_OVERRIDE_MAKEMIGRATIONS = True Django settings.

2.3.0

  • Handle making a column NOT NULL with a Django default value as backward incompatible. This should have been the case from the beginning, but it was not. When one uses the django-add-default-value lib, the operation should still be compatible.
  • Improve behaviour of the --include-migrations-from option. When the given filename is missplelled, fail instead of linting all migrations. When the file is empty, lint no migrations instead of linting all migrations.
  • Update libraries used for testing (tox, flake8, etc.)

2.2.2

  • Don't pin dependencies but only define minimal versions

2.2.1

Fixed bug:

  • Correctly detect apps.get_models when on multiple lines in data migration

2.2.0

  • Make summary output more friendly (Thanks to @vald-phoenix)
  • Add forgotten documentation about IgnoreMigration
  • Don't pin the appdirs strictly to 1.4.3, but allow higher versions

2.1.0

  • Detect in data migrations if models are imported the correct way or not

2.0.0

  • Add linting on data migrations that will raise warnings
  • Add --quiet warning option to suppress warning messages
  • Add --warnings-as-errors option to handle warnings as errors

1.5.0

  • Rework documentation. Make README smaller and clearer. Move detailed documentation to docs/ folder.
  • Add Django 3.0 to test matrix.

1.4.1

  • Update testing dependencies (mysqlclient, Django 2.2 and black)

1.4.0

  • Add --include-migrations-from option to only consider migrations specified in a given file. No matter if the migrations are selected from a git commit or not, we only select the ones in the given file.
  • Add --quiet {ok,ignore,error} option to remove different or multiple types of messages from being printed to stdout.
  • Make detection of problematic table and column a bit more resilient for UX.
  • Add Python 3.8 to test matrix and update test dependencies.

Fixed bugs:

  • Handle adding many to many fields correctly.

1.3.0

  • Add --exclude-migration-tests option to ignore backward incompatible migration tests.
  • Do not falsely detect dropping NOT NULL constraint.
  • Detect DROP TABLE backward incompatible migration.
  • Detect adding a UNIQUE constraint as backward incompatible migration.
  • Handle when Django tries to generate the SQL of a migration but raises an exception because it cannot find the name of a certain constraint (because it has been dropped already).

Internal change:

  • Differentiate different database vendors during SQL analysis.

1.2.0

  • Add --unapplied-migrations and --applied-migrations mutually exclusive options in order to respectively lint only unapplied or applied migrations.
  • When loading migration starting from a git ref, cross the found migrations with the currently loaded migrations in the project.
  • Add --project-root-path which allows to specify the root path which is used for finding the .git folder. (thanks to @linuxmaniac)

1.1.0

  • Improve speed of ignored migration through the IgnoreMigration operation. Instead of generating their SQL, we verify if the Operation class is present. Thus we don't have to wait for the SQL generation. Also improves the caching strategy.

Breaks some internal APIs, so minor update to 1.1.0.

1.0.0

Breaking changes of the linter usage. The linter now is a Django management command. It should be used with a python manage.py lintmigrations followed by the usual options. Additionally, the linter now needs to be added the to the INSTALLED_APPS in your Django settings.

  • The linter is now much faster: we don't setup django once for each migration
  • The linter is now more robust: we rely on Django internals to discover migrations
  • Clean up of the testing setup: it is cleaner, less brittle and we have more confidence that it works
  • Added support for Django 2.2
  • Dropped support for Python 3.4

Fixed bugs:

  • Made the cache database-dependent. Between multiple databases, some migrations would be considered correct while they are not on the used DB.
  • Adding an erroneous migration to the ignore list on the second run would get the migration content from the cache and not ignore it.

0.1.5

  • Bug fix: handle migration files with spaces in their name by quoting the migration name

0.1.4

  • Explicitly test for mysql, sqlite3 and postgresql
  • Fix alter column type detection in postgresql
  • Do not create cache folder when -no-cache option
  • Fix tests on Windows
  • Use the same Python interpreter as used for launching the linter, instead of manually trying to re-create the path

0.1.3

  • Fixes migrations that are ignored to generate empty SQL, that PostgreSQL complains about. It throws an exception making migrations fail, that are in fact valid. (Thanks to @fevral13 and @mes3yd)
  • Add options -V and --version to show the current linter version

0.1.2

  • Bug fix: handle when the linter is called in the working dir django-migration-linter .
  • Bug fix: don't assume that the git root is at the same path as the django project

0.1.1

  • Fix caching when app is in a folder and not at the root of the project
  • Do not check for .git folder at root, because it might be located somewhere else. Let git itself do the job
  • Make some imports relative

0.1.0

The django migration linter is now set to a Beta version, instead of Alpha since it has been used for quite some time.

Version 0.1.0 comes with:

  • Possibility to ignore migration files entirely (without specifying them on the command line)
  • This can be used by adding the migration operation IgnoreMigration() in the migrations operations list. See readme
  • Caching. We cache failed and succeeded migrations (w.r.t. migration linting) in a cache file.
  • Each migration file is stored as the MD5 hash of its content with the result of the linting

Other things:

  • Added support for Python 3.7
  • Added support for Django 2.1
  • The codebase is now in black format to improve Python-code readability
  • 2019 ! Happy new year

0.0.7

  • Minor bug fix when no errors detected

0.0.6

  • Use logger correctly
  • Drop django 1.10 support

0.0.5

  • Only consider added migrations during linting
  • Change readme to rst format (for PyPi)
  • Added examples folder
  • Add django (at least 1.10) as requirement for the linter

0.0.4

Assure compatibility for multiple python and django versions.

  • Try to improve PyPi readme
  • Better error messages

0.0.3

  • Made a mistake and accidentally deleted 0.0.2 from PyPi

0.0.2

  • Python 3 compatibility

  • Faster migration gathering

  • Code base refactoring

  • Test base refactoring

0.0.1
