Question

I am having a problem with admin.autodiscover(). I just moved my site from the system I was building it on to the server it will stay on for production use. The system that was being used to build it is Windows 7 however the production server is Debian Squeeze 64bit.

The problem is that I am getting the error The model UserProfile is already registered. I am not having this problem with the Windows 7 computer, only once it moves to Debian it does.

admin.py

class UserProfileadmin(admin.ModelAdmin):
    list_display = ['user', 'country', 'totalflights', 'totalhours', 'hub']
    search_fields = ['user']
    list_filter = ['hub']
    def formfield_for_foreignkey(self, db_field, request, **kwargs):
         if db_field.name == 'hub':
             kwargs['queryset'] = Airports.objects.filter(hub=True)

    return super(UserProfileadmin, self).formfield_for_foreignkey(db_field, request, **kwargs)

admin.site.register(UserProfile,UserProfileadmin)
class PilotRankadmin(admin.ModelAdmin):
    list_display = ['ranktitle', 'minimumhours', 'pay']
    search_fields = ['ranktitle']

admin.site.register(PilotRank, PilotRankadmin)

class PIREPadmin(admin.ModelAdmin):
    list_display = ['user', 'flightnumber']
    search_fields = ['ranktitle']

admin.site.register(PIREP, PIREPadmin)

Any ideas? I have never had this before when working on a Windows system then moving to a Linux system for production.

Answer 1

Can you post the error stack details…
have you tried using admin.site.unregister(UserProfile) just before you call register ?

edit:
this seems to be working fine for me –

if not admin.site._registry.has_key(UserProfile):
        admin.site.register(UserProfile)
