On the Django IRC channel, I was helped through some resources for replacing the auth systems's User model with my own extended version. Here are the notes I made. Note that it was 2:30 am local time, beware hacker fatigue syndrome.
[02:18] <harmless> phew, that was NOT easy [02:18] <harmless> note to all: [02:18] <harmless> if you wish to replace the auth User model with an extended version, you must do the following: [02:19] <harmless> 1. patch the createsuperuser function in core/management.py to catch ObjectDoesNotExist rather than users.UserDoesNotExist [02:20] <harmless> 2. ensure that your model's META specifies module_name = "users" [02:21] <harmless> 3. provide a _module_create_user function that does all of what django.models.auth.User's does, plus inits your new fields [02:21] <harmless> 3 a. note that it's easier to use keyword arguments here, as it's not clear what the field order is when extending a model [02:21] <harmless> 4. wipe your entire database every time you make a change. [02:22] <harmless> and that pretty much did it for me, i've got my own user class being used successfully for auth and admin, and it's a single nice class in the admin interface. [02:22] <harmless> so maybe next time i need to do this, this transcript will be a quick google search away :) [02:25] <alect> perhaps you should wikify it [02:35] <paulproteus|lapt> I'm with alect on this one. (-: [02:36] <harmless> well, i'm not sure it's wikiworthy at this point [02:36] <harmless> it looks like it's changing right away anyways [02:36] <harmless> but i'll paste it in with a "late night hacking" warning
Missing here is step 2b, ensure that your model's META specified replaces_module="auth.users", and step 5, you must copy the original models' entire META.admin section if you wish to change it at all.
Here's what my model looks like at this point:
class User(users.User): gamename = meta.CharField("Game Name", maxlength=100, blank=True) url = meta.CharField(maxlength=100, blank=True) description = meta.TextField(blank=True) # SNIP a few more extra model attributes class META: replaces_module = 'auth.users' module_name = "users" verbose_name = _('User') verbose_name_plural = _('Users') module_constants = { 'SESSION_KEY': '_auth_user_id', } ordering = ('username',) exceptions = ('SiteProfileNotAvailable',) admin = meta.Admin( fields = ( (None, {'fields': ('username', 'password_md5')}), (_('Personal info'), {'fields': ('first_name', 'last_name', 'email')}), (_('Extended info'), {'fields': ('gamename', 'url', 'description')}), (_('Permissions'), {'fields': ('is_staff', 'is_active', 'is_superuser', 'user_permissions')}), (_('Important dates'), {'fields': ('last_login', 'date_joined')}), (_('Groups'), {'fields': ('groups',)}), ), list_display = ('username', 'gamename', 'first_name', 'last_name', 'is_staff'), list_filter = ('is_staff', 'is_superuser'), search_fields = ('username', 'first_name', 'last_name', 'email', 'gamename', 'description'), )
NOTE
If you're using development django, these steps change a bit.
- you won't need to modify createsuperuser (step 1 above)
- you will need to change
password_md5
above to justpassword
anywhere it appears in your model's META - specifically, inadmin.fields
Comments
- How does this work in the magic-removal branch?
- Apparently the modern version of django.contrib.auth can assign a model to get_profile for attatching extra data to a User.
