How to install:
1. Put the "badges" directory somewhere in your python path
2. Add "badges" to your installed apps (in the settings.py file)
3. Define the badges you wish to have on your site in the "badges.py" file of the badges app
4. OPTIONAL: If you want to use the pre-made badges overview/checklist page,
add this to your main "urls.py" file:
urlpatterns += patterns('',
How to make badges:
I would encourage you to create a "meta_badges.py" file and import it at the bottom of your
Every badge is subclassed from "badges.MetaBadge"
Here is an example badge that is awarded to users who fill in all the fields on their profile:
from myapp.models import UserProfile
id = "autobiographer"
model = UserProfile
one_time_only = True
title = "Autobiographer"
description = "Completed the User Profile"
level = "1"
def get_user(self, instance):
def check_email(self, instance):
The badges are awarded using the post_save signal. So whenever a member of the 'model' is saved,
it checks to see if the user should be awarded a badge. In this case the model is "Profile" so
whenever a user profile is saved, the badges app checks each of the conditions and if they are
all True, then the badge is awarded.
The "get_user" method is passed the same instance as the condition checks and needs to return the
user who should receive the badge... the default is instance.user
The "one_time_only" attribute determines whether a user can earn the badge more than once. If a
badge was awarded for writing a post that got 1000 views, you may want to award it for
EACH post that gets 1000 views, instead of just the first time.
There are some badge info attribute which defines the information about the badge that will be
shown on your website:
id - the unique name that will be used to identify the badge in your database. The
reason fo this is so that you can change the title, description, and level
title - the Name of the badge as it will appear on the website.
description - a short description of the badge as it will appear on the website.
level - badges are either easy (bronze/b), medium (silver/s), or hard (gold/g) to get. It
would not be very hard to change the levels to something else like numbers.
Conditions are callback functions. Any methods of your badge class whose names start with "check"
will be passed an instance of the model instance that has just been saved. If all the conditions
return "True," the badge will be awarded (unless it's a one-time-only and the user already has it)
When a badge is awarded, a signal is fired (found in badges.signals). The "sender" keyword argument
is the metaBadge you defined (Autobiographer in this case), and NOT the badge model instance that
is automatically created. The "user" keyword argument is the user who the badge was awarded to, and
the "badge" keyword argument is the model instance of the badge in the database (badges.models.Badge)

Manually Awarding a Badge:
You can manually award a badge to a user using the "award_to" method on the Badge model instance.
Example: Award a random badge to a random user...
from django.contrib.auth.models import User
from badges.models import Badge
random_user = User.objects.order_by("?")
random_badge = Badges.objects.order_by("?")
