Redux: Extending the Django User model with inheritance
I just packaged up and released a small bit of code last night. Mostly because I wanted to extract it from my project to reuse later, but also because I thought it was cool enough to share. It really is small. Just a few lines of code, as it's basically just a clever use of the InheritanceQuerySet provided by django-model-utils. I suppose I could have copied that bit of code into my app, but django-model-utils is small and has some great stuff that I've started using in all of my projects. So, allow me to share why I thought this bit of code is useful. I have a project that I'm working on that requires several different classes of authenticated users. Each user class has its own required fields and foreign keys and such. It was all complicated enough that a single user profile model wasn't going to cut it. So I tried using a generic foreign key on the user profile that could be used to point to the "real" profile. Wow, was that a mess. Another requirement of my project is that all the users belong to a hierarchy. When a given user logs in, they need to … -

Auto-Detecting Anomalies in Your Key Metrics
As your web application grows, so does the importance of monitoring. With more cogs in the machine, more things can go wrong. At Yipit, we want to find and fix application level errors in a timely fashion. While our test suite catches most bugs, some inevitably seep through. Whereas many tools such as Ylastic, AWS, Chartbeat, Munin, and Ganglia help mitigate the monitoring headache on the machine and network level, they don’t do as great a job at the application level. Where we envision Xenia Monitoring of Application Level Metrics at Yipit At Yipit, our application metrics consist mostly of user actions, or events. We log everything from opening our daily email and browsing the web interface to making an API call and using our mobile app. Up until now, we’ve relied on human monitoring, user complaints, and automated custom scripts to detect worrisome trends in our application metrics. However, our recent growth forced us to look into more scalable solutions to this problem. As such, we have begun developing an automated anomaly detection system for monitoring application level metrics more intelligently, code-named Xenia. Xena - the Warrior Princess Xenia (Not the Warrior Princess) The main purpose of Xenia is … -

My BaseModel
When I build projects in Django I like to have a 'core' app with all my common bits in it, including a BaseModel. In that BaseModel I'll define the most basic fields possible, in this case a simple pair of created/modified fields built using custom django-extension fields. # core/models.pyfrom django.db import modelsfrom django.utils.translation import ugettext_lazy as _from core.fields import CreationDateTimeField, ModificationDateTimeFieldclass BaseModel(models.Model): """ Base abstract base class to give creation and modified times """ created = CreationDateTimeField(_('created')) modified = ModificationDateTimeField(_('modified')) class Meta: abstract = TrueYou'll notice I also have core.fields defined. That is because (unless things have changed), django-extensions doesn't work with South out of the box. Hence the file below where I extend those fields to play nicely with my migration tool of choice.# core/fields.pyfrom django_extensions.db.fields import CreationDateTimeField, ModificationDateTimeFieldclass CreationDateTimeField(CreationDateTimeField): def south_field_triple(self): "Returns a suitable description of this field for South." # We'll just introspect ourselves, since we inherit. from south.modelsinspector import introspector field_class = "django.db.models.fields.DateTimeField" args, kwargs = introspector(self) return (field_class, args, kwargs) class ModificationDateTimeField(ModificationDateTimeField): def south_field_triple(self): "Returns a suitable description of this field for South." # We'll just introspect ourselves, since we inherit. from south.modelsinspector import introspector field_class = "django.db.models.fields.DateTimeField" args, kwargs = introspector(self) return (field_class, args, … -
