Mixins for model cleanup methods and validation error concatenations
* Free software: MIT license
* Documentation: https://django-model-cleanup.readthedocs.io.
Features of CleanMixin
----------------------
* Provides `clean` method implementation
* Call to `full_clean` will result in call to all `clean_*` methods
* All methods will get called regardless of validation errors - get all errors at once
* Auto mapping of errors to field names based on clean method names, if errors have no error_dict
Quickstart
----------
Install Django Model Cleanup::
pip install django-model-cleanup
Add mixin in your models and enjoy `clean_` method collection and error concatenation when `full_clean` is called:
.. code-block:: python
from django.core.exceptions import ValidationError
from django.db import models
from django.utils.translation import ugettext_lazy as _
from django_model_cleanup import CleanMixin, ExtensibleValidationError
class SomeModel(CleanMixin, models.Model):
lorem = models.CharField(max_length=10, blank=True)
def clean_foo(self):
raise ValidationError('Foo is bad')
def clean_bar(self):
raise ExtensibleValidationError({'bar': _('Bar is wrong cause %s > %s!')}, code='bar', params=(2, 1))
def clean_legacy(self):
# We can't init ValidationError as one-liner, cause dict + params are not compatible
# We need to wrap a message in ValidationError and put that in dict indicating a field
msg = _('Bar legacy error %s > %s!')
error = ValidationError(msg, code='bar', params=(7, 5))
raise ValidationError({'bar': error})
Each error handling and concatenation is no longer required:
.. code-block:: python
# This is not longer required:
def clean(self):
errors = []
try:
self.clean_foo()
except ValidationError as ex:
errors.append(ex)
errors = []
try:
self.clean_bar()
except ValidationError as ex:
errors.append(ex)
errors = []
try:
self.clean_legacy()
except ValidationError as ex:
errors.append(ex)
if errors:
raise ValidationError(errors)
Running Tests
-------------
Does the code actually work?
::
$ pipenv install --dev
$ pipenv shell
$ tox
We recommend using pipenv_ but a legacy approach to creating virtualenv and installing requirements should also work.
Please install `requirements/development.txt` to setup virtual env for testing and development.
