Automatically validates when you call your model’s save()

Project description

Make save call full_clean.

Do you think Django models save method will validate all fields (i.e. call full_clean) before saving or any time at all? Wrong!

I discovered this awful truth when I couldn’t understand why a model object with an email field (without blank=True) could be saved with an empty string as email address.

Installing

First add the application to your Python path. The easiest way is to use pip:

pip install django-smart-save

You should install by downloading the source and running:

$ python setup.py install

Configuring

Make sure you have django.contrib.auth installed, and add the smart_save application to your INSTALLED_APPS list:

INSTALLED_APPS = (
    ...
    'django.contrib.auth',
    'smart_save',
)

You can specify a different method name in your project settings (default: save_if_valid):

SMART_SAVE_METHOD = ‘my_save’

Usage Overview

It is simple:

>>> user = User(username="chris")
>>> user.save_if_valid()
True
>>> user = User(username="")
>>> user.save_if_valid()
False
>>> user._errors
{'username': ['This field cannot be blank.']}
