Django Validator

Validate Django settings, models, URLs, serializers, and production rules with configurable strictness and explicit pass or fail status.

Developer Input

Django rule validation

Paste Django code or a multi-file project sample

# FILE: settings.py
SECRET_KEY = "hardcoded-key"
DEBUG = True
ALLOWED_HOSTS = ["*"]

# FILE: models.py
class Product(models.Model):
    name = models.CharField(max_length=120, null=True)
    category = models.ForeignKey("Category")

How to use this developer tool

Paste the target Django source.
Select automatic or file-specific validation.
Enter basic, recommended, strict, or production strictness.
Run validation and review passed, warning, error, and skipped rules.

What this developer tool does

The validator evaluates explicit Django rules and returns a pass or fail status rather than a broad advisory audit.

Target detection → profile rules → pass/warn/error classification → validation status

Static validation cannot confirm database state, installed apps, migrations, imported objects, or runtime middleware behavior.

Example

A ForeignKey without on_delete fails the model rule set, while a missing __str__ method is normally a warning.

Tips for better output

Use production strictness before deployment.
Include file markers to select accurate rule sets.
Resolve errors before warnings.
Use Django Checker for broader advisory checks.

FAQ

How is Validator different from Checker?

Validator applies explicit pass/fail rules, while Checker reports broader configuration and convention concerns.

Can I choose strictness?

Yes. Basic, recommended, strict, and production-oriented profiles are supported through the strictness input.

Does it validate Python syntax?

It performs limited structural checks, not a full Python parser or interpreter.

Can it validate DRF serializers?

It checks common ModelSerializer model and fields declarations.

Does it run migrations?

No. It does not access the project or database.
