django-basis 
¶
Simple reusable django app for basic model functionality.
Usage of TimeStampModel¶
Adds created_at and updated_at to models.
from basis.models import TimeStampModel
class Person(TimeStampModel):
name = models.Charfield(max_length=50)
person = Person.objects.create(name="Fredrik"))
print person.created_at # datetime object1
person.name = "Rolf"
person.save()
print person.created_at # (datetime at the moment of the creation)
print person.updated_at # (datetime at the moment of the update)
Usage of PersistentModel¶
Safe deletion of objects.
from basis.models import PersistentModel
class Person(PersistentModel):
name = models.Charfield(max_length=50)
person = Person.objects.create(name="Fredrik"))
# SafeDelete person (safe delete)
person.delete()
print Person.objects.all().count() # 0 - excludes deleted users
print Person.all_objects.all().count() # 1 - includes deleted users
# Restore deleted person
person = Person.all_objects.get(id=person.id)
person.restore()
# If you really want to delete the object
person = Person.objects.create(name="Fredrik"))
person.delete(force=True)
Usage of BasisModel¶
Includes the functionality of both PersistentModel and TimeStampModel, while adding the fields created_by and updated_by.
from basis.models import BasisModel
class Person(BasisModel):
name = models.Charfield(max_length=50)
# Save changes on objects and register who did it
person = Person.objects.get(id=id)
person.name = "Fredrik"
person.save(current_user=request.user)
# Or create a new object and register who did it
person = Person.objects.create(name="Fredrik", current_user=request.user)
# See meta info about the object
print person.created_by # user object (creator)
print person.updated_by # user object (updater)
Models¶
Usage of BasisSerializer¶
Makes sure BasisModel objects created and updated have the created_by and updated_by fields set.
