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"},
    ]
}

By default only your project apps are checked but you can use include_apps option to specify apps to check (including third party apps):

EXTRA_CHECKS = {
    # use same names as in INSTALLED_APPS
    "include_apps": ["django.contrib.sites", "my_app"],
    ...
}

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()

Checks

Models

• extra-checks-config - settings.EXTRA_CHECKS is valid config for django-extra-checks (always enabled).
• model-attribute - Each Model in the project must have all attributes from attrs setting specified.
• model-meta-attribute - Each Model.Meta in the project must have all attributes from attrs setting specified.
• model-admin - Each model must be registered in admin.
• field-file-upload-to - FileField/ImageField must have non empty upload_to argument.
• field-verbose-name - All model's fields must have verbose name.
• field-verbose-name-gettext - verbose_name must use gettext.
• field-verbose-name-gettext-case - Words in text wrapped with gettext must be in one case.
• field-help-text-gettext - help_text must use gettext.
• field-text-null - text fields shoudn't use null=True.
• field-boolean-null - prefer using BooleanField(null=True) instead of NullBooleanField.
• field-null - don't pass null=False to model fields (this is django default).
• field-foreign-key-index - ForeignKey fields must specify db_index explicitly (to apply to unique together only: when: unique_together).

DRF Serializers

• drf-model-serializer-extra-kwargs - ModelSerializer's extra_kwargs must not include fields that specified on serializer.
