Django Validate on Save

Automatically call full_clean() on models during save() to prevent invalid data being saved.

Surprisingly, this does not happen by default, apparently for backwards compatibility reasons.

Author: Francis Devereux, Bright Interactive.

Adding to your Django Project

For Django 1.6, 1.5, 1.4 or 1.3:

Call validate_on_save.validate_models_on_save('your_app_name') from your app's models.py (I put this call near the end of models.py, not sure whether this matters).

For Django 1.7 or 1.8:

Create an AppConfig (https://docs.djangoproject.com/en/1.8/ref/applications/) and call validate_on_save.validate_models_on_save('your_app_name') in its ready() method.

You need to configure the app to use the new, app-specific AppConfig by editing its __init__.py file, and adding the following:

default_app_config = 'package.leading.to.NameOfNewAppConfig'

Publishing releases to PyPI

Only Bright Interactive employees can publish a release. Ensure you have a .pypirc file in your home directory configured to publish to the bright PyPI account (real password has been redacted).

[pypirc]
servers = pypi

[server-login]
username:bright
password:******

To publish a new version of django-validate-on-save to PyPI, set the __version__ string in validate_on_save/__init__.py, then run:

# Run the tests against multiple environments
tox
# Publish to PyPI
./setup.py publish
# Tag (change 1.0.0 to the version you are publishing!)
git tag -a v1.0.0 -m 'Version 1.0.0'
git push --tags

Running the tests

To run the tests against the current environment:

./manage.py test

To run the tests against multiple environments, install tox using pip install tox, make sure you're not currently in a virtual environment, then simply run tox:

tox

Changelog

1.1.4

• Initial Python 3 support. Tox passes but I think that there is still work to do e.g. adding u prefix to strings.

1.1.3

• No code changes - version number bump required because I uploaded a broken package of 1.1.2 to PyPI

1.1.2

• Test against Django 1.8
• Avoid using deprecated django.db.models.loading on Django 1.7+

1.1.1

• Don't load all the apps when setting the signals for the models to avoid a circular import

1.1.0

• Add support for Django 1.7

1.0.0

• Initial release
