Vim for Django... a hell of a good start

django-user-registery

I needed to build an auditing system in django and it got me to thinking... What is a graceful way of being to see and get an authenticated user in the context of a model or signal?

I didn't immediately see one so I wrote django-user-registry


I have since deprecated this for function that looks through the stack to find the request signature.
If it finds the request it uses the user from there.

---- Deprecated (Does't work on multithreaded (read all) servers :P ----

The concept is simple create a small middleware class that registers an authenticated user with with a registry class on request and unregisters the user on result.

Then in your model/signal code you can check for and access a user if one exists in the current context.

This code is little naive... it definitely would fall down in a multithreaded environment. Any ideas? The only other way that I can think of implementing it is to walk back up the stack looking for a request...

Example
(in settings.py)

MIDDLEWARE_CLASSES = (
'django.middleware.common.CommonMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',

# 3rd party
# allow access to authenticated users in models and signals
'user_registry.middleware.UserRegistryMiddleware',
)

(in foo/signals.py)

from django.db.models.signals import post_save, post_delete, m2m_changed
from django.dispatch import receiver

from user_registry import UserRegistry

def alert_on_user():
print "alert_on_user"
if UserRegistry.has_user():
user = UserRegistry.get_user()
print user

@receiver(post_save)
def post_save_audit(sender,**kwargs):
alert_on_user()

@receiver(post_delete)
def post_delete_audit(sender,**kwargs):
alert_on_user()

@receiver(m2m_changed)
def m2m_changed_audit(sender,**kwargs):
alert_on_user()


Update dj_jsurls is now django-jsurls

In order to follow the established plugin naming convention dj_urls is now django-jsurls. Also I got sick of typing dj_jsurls so the js root is now jsurls.

There is templatetags/jsurls - get_jsurls_static_prefix and urls.jsurls_urlpatterns to work around the fact that django.contrib.staticfiles.staticfiles_urlpatterns eats all /static/ paths

Lastly, there is a manage.py generate_static_jsurls to build the static production version of the jsurls.js file.

DRY out your urls (in JS)

(update: changed url repository)

When it come to xhr heavy JS code, I hate hard coding in urls. This isn't good practice on the Django side and it is not good practice on the JS side. While I was working in ROR for a spell, I found a plugin on github toretore/javascript_routes that built off of ROR routes system. Upon moving back to Django I wanted the same functionality, so I built a pluggable app at sjzabel/django-jsurls.

Right now it is view designed for development use but I'll have management tool to statically generate it for productions here soon.

Django, login required mixin, mixed into all class based generic views

Django, aaaaaaaah...

After a two year stint using Ruby on Rails, I am back in the loving arms of Django.

I've been quite pleased to see that it is growing up but still keeping all the things that I loved about it (the intuitiveness, the flexibility, the ease of hacking, the spectacular documentation, etc...)

So a link Eric Olscher : Large Problems (mostly solved)

In this series of blog posts Eric talks about a number of issues that we had to hand roll solutions to when I was beginning with Django

Pomodoro + Adium + Applescript = Fun!

Two useful little scripts for changing your Adium status at the beginning and end of a Pomodoro session. (I got sick of doing this by hand after my first session :P)

- @Start

tell application "Adium"
go away with message "back at " &(time string of ((current date) + 25 * minutes))
end tell

- @Finish

tell application "Adium"
go available
end tell

I love the django community (make your own my little django pony)

Look Ma... my first ubiquity script

I have been tracking my calories
A friend has a nice tracking site
A well known site has a lot of nutritional data
I do not do data entry
+I have enough morals not to spider the site :P

I now know how to write ubiquity scripts :)

Mumboe's Auto Extraction process mentioned on ReadWriteWeb

We got a pretty nice writeup from readwriteweb.

A little something svn to put in your .bashrc pipe

Today's helpful trickery. In the course of debugging I want to hit reset, here is helpful little snippet

alias _svn_revert_all="svn status | awk '{print $2}' | xargs svn revert"

def __init__(self, introduction)

It was no longer productive to intermix various tech notes and recipes with random drone noise about my life. Additionally, after checking the blogs of the last three people that I have interviewed, it has become increasingly apparent that a separation of church and state is a good thing.
