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.
More info:
- “Why doesn’t django’s model.save() call full clean?”
- “Model docs imply that ModelForm will call Model.full_clean(), but it won’t.”
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.']}
