Additional fields for(ever) Django.

- Python 2.7, 3.6
Documentation¶
Documentation is available on Read the Docs.
Main features and highlights¶
- MD5Field.
Installation¶
Install latest stable version from PyPI:
pip install django-strawberry
or latest stable version from GitHub:
pip install https://github.com/barseghyanartur/django-strawberry/archive/stable.tar.gz
or latest stable version from BitBucket:
pip install https://bitbucket.org/barseghyanartur/django-strawberry/get/stable.tar.gz
Usage¶
MD5 field¶
In case you want to have an MD5 field populated from another field of the same model.
Example 1¶
myapp/models.py
from django.db import models
from strawberry.fields import MD5Field
class MyModel(models.Model):
title = models.CharField(max_length=255)
title_hash = MD5Field(
populate_from='title',
null=True,
blank=True
)
def __str__(self):
return self.title
myapp/example.py
from myapp.models import MyModel
mymodel = MyModel.objects.create(title="Lorem7")
print(mymodel.title_hash)
'd48a712e77902d0558a3721d9a4740c9'
Example 2¶
The populate_from argument can also be a callable, that would expect the model instance as an argument. Thus, example identical to the first one would be:
myapp/models.py
from django.db import models
from strawberry.fields import MD5Field
def strip_title(instance):
return instance.title.strip()
class MyModel(models.Model):
title = models.CharField(max_length=255)
title_hash = MD5Field(
populate_from=strip_title,
null=True,
blank=True,
)
def __str__(self):
return self.title
myapp/example.py
from myapp.models import MyModel
mymodel = MyModel.objects.create(title=" Lorem7 ")
print(mymodel.title_hash)
'd48a712e77902d0558a3721d9a4740c9'

Release history and notes¶
Sequence based identifiers are used for versioning (schema follows below):
major.minor[.revision]
- It’s always safe to upgrade within the same minor version (for example, from 0.3 to 0.3.4).
- Minor version changes might be backwards incompatible. Read the release notes carefully before upgrading (for example, when upgrading from 0.3.4 to 0.4).
- All backwards incompatible changes are mentioned in this document.
