Add's updated and created fields to a model if mixed in. Example that uses the name as the representation: class Company(models.Model, UnicodeReprMixIn): """ A representation of a comic book company. """ name = models.CharField(max_length=255) slug = models.SlugField() logo = models.ImageField(upload_to=os.path.join('upload', 'company_logos')) url = models.URLField(verify_exists=True) _unicode = "name"
This model is designed for my webshop. The Client-object is very 'stretch-able' by defining more fields to the client. These extra fields ares stored in the ClientConfig-object. Be sure to create a new Client-instance first and SAVE it! Without a client.id the ClientConfig won't work.
This is a basic stub for a model that you can use to easily add customizable JSON serialization to your models. Make your model inherit from JsonableModel, and then define the models/yourmodel.json template with whatever information from the model that you want to make available.
Example mixin for creating and removing thumbnails on a model. Also adds some methods for accessing an url for an image size. It might be a better idea to use a custom image field instead of this approach. Idea for getting the image url for different sizes from http://code.google.com/p/django-photologue Example usage <pre> >>> p.get_small_image_url() u'http://127.0.0.1:8000/site_media/photos/small_someimage.jpg' </pre>
I wanted to store ipv4 and ipv6 ip's in django but I wanted to use the postgresql inet network field type: http://www.postgresql.org/docs/8.3/static/datatype-net-types.html and I wanted to use IPy.py IP objects in python. I followed these very helpful examples along with the django documentation: http://vaig.be/2009/03/numeric-ip-field-for-django.html http://www.djangosnippets.org/snippets/1381/ It took me awhile to figure out how this works (not that I completely understand it now..) and figured I would share it. If anyone finds problems with this or can make it better I will definitely use it.
This snippet updates http://www.djangosnippets.org/snippets/383/ for Django 1.0+, and adds support for sqlite3. Original snippet text: A CompressedTextField to transparently save data gzipped in the database and uncompress at retrieval.
This snippet provides a uuid field for models, improving on the work in http://www.djangosnippets.org/snippets/335/
A mixin to define permissions on models. This is more of an abstract model to subclass/customise than a plug-in solution. Explanations are [here](http://www.muhuk.com/2009/05/django-permission-system/).
Getting a new ID according to the content type.
Used for models with active_date and inactive_date. Adds an "active" filter to get only active items
With these models, you can use your Django's database directly as backend for PowerDNS server (tested with MySQL). License: GNU GPL. More info: http://downloads.powerdns.com/documentation/html/configuring-db-connection.html#CONFIGURING-MYSQL
This example shows, how to use database views with django models. NewestArticle models contains 100 newest Articles. Remember, that NewestArticle model is read-only. Tested with mysql.
Many of my projects heavily depend on other non-django projects to create the databases. To simplify setting up a test environment, I modified the simple test runner so that it will treat all models as managed. This will also allow for easier test set up against models that point to views. You can directly populate the view with the specific data needed for the tests, instead of populating (potentially) several models.
You can use `UrlModel` to provide URL functionality to any instance of any model and any language (language support can be removed from this). Each model must have own view method, that returns HttpResponse. I was inspired by Flatpages. It is useful for small sites and static pages. `class Page(UrlModel): text = models.TextField() def view(self, request) # do something here return HttpResponse(...)`
Runs model methods on save, create, update, delete Similar to Rails hooks **Usage:** *in models.py* from myproject.hooks import connect_hooks class MyModel(models.Model): #... # only on first save of a newly created object def before_create(self): print self def after_create(self): print self # not on first save of a newly created object def before_update(self): print self def after_update(self): print self # any save, new object or update def before_save(self): print self def after_save(self): print self # delete, self is still available after delete def before_delete(self): print self def after_delete(self): print self **connect_hooks(MyModel)**
