# makemigrations
|
|
|
|
The linter can override behaviour of the [Django makemigrations command](https://docs.djangoproject.com/en/dev/ref/django-admin/#django-admin-makemigrations).
|
|
|
|
Either:
|
|
* by specifying the `--lint` option in the command line
|
|
* by setting the `MIGRATION_LINTER_OVERRIDE_MAKEMIGRATIONS` Django setting to `True`
|
|
|
|
## Example
|
|
```
|
|
$ python manage.py makemigrations --lint
|
|
|
|
Migrations for 'app_correct':
|
|
tests/test_project/app_correct/migrations/0003_a_column.py
|
|
- Add field column to a
|
|
Linting for 'app_correct':
|
|
(app_correct, 0003_a_column)... ERR
|
|
NOT NULL constraint on columns
|
|
Deleted tests/test_project/app_correct/migrations/0003_a_column.py
|
|
```
|
|
|
|
## Options
|
|
|
|
Among the options that can be given, additionally to the default `makemigrations` options, you can count the options
|
|
to configure what should be linted:
|
|
* `--database DATABASE` - specify the database for which to generate the SQL. Defaults to *default*.
|
|
* `--warnings-as-errors` - handle warnings as errors and therefore return an error status code if we should.
|
|
* `--exclude-migration-tests MIGRATION_TEST_CODE [...]` - specify backward incompatible migration tests to be ignored using the code (e.g. ALTER_COLUMN).
