Django Extra Checks

Useful checks for Django Checks Frameworks

Settings

To enable some check define EXTRA_CHECKS setting with a dict of checks and its settings, eg:

EXTRA_CHECKS = {
    "checks": [
        # require non empty `upload_to` argument.
        "field-file-upload-to",
        # use dict form if check need configuration
        # eg. all models must have fk to Site model
        {"id": "model-attribute", "attrs": ["site"]},
        # require `db_table` for all models, increase level to CRITICAL
        {"id": "model-meta-attribute", "attrs": ["db_table"], "level": "CRITICAL"},
    ]
}

To ignore model warnings you can use ignore_checks decorator, eg:

from extra_checks import ignore_checks, CheckID

@ignore_checks("model-attribute", "X011", CheckID.X050)
class MyModel(models.Model):
    image = models.ImageField()
