I am using a database router hence i have two databases for my application. One database for default django data and the other one.
In my admin i have override the save_model function in order to save the created_by variable, but i am unable to do this.
Cannot assign "<User: testuser>": the current database router prevents this relation.
database router:
from django.conf import settings
class DatabaseAppsRouter(object):
def db_for_read(self, model, **hints):
"""Point all read operations to the specific database."""
if settings.DATABASE_APPS_MAPPING.has_key(model._meta.app_label):
return settings.DATABASE_APPS_MAPPING[model._meta.app_label]
return None
def db_for_write(self, model, **hints):
"""Point all write operations to the specific database."""
if settings.DATABASE_APPS_MAPPING.has_key(model._meta.app_label):
return settings.DATABASE_APPS_MAPPING[model._meta.app_label]
return None
def allow_relation(self, obj1, obj2, **hints):
"""Allow any relation between apps that use the same database."""
db_obj1 = settings.DATABASE_APPS_MAPPING.get(obj1._meta.app_label)
db_obj2 = settings.DATABASE_APPS_MAPPING.get(obj2._meta.app_label)
if db_obj1 and db_obj2:
if db_obj1 == db_obj2:
return True
else:
return False
return None
def allow_syncdb(self, db, model):
"""Make sure that apps only appear in the related database."""
if model._meta.app_label in ['south']:
return True;
elif db in settings.DATABASE_APPS_MAPPING.values():
return settings.DATABASE_APPS_MAPPING.get(model._meta.app_label) == db
elif settings.DATABASE_APPS_MAPPING.has_key(model._meta.app_label):
return False
return None
admin:
class SomeEntityAdmin(admin.ModelAdmin):
def save_model(self, request, obj, form, change):
user = request.user._wrapped if hasattr(request.user,'_wrapped') else request.user
if not obj.created_by:
obj.created_by = user
obj.save()
I have even tried to define a different database by using save(using='thedb') but that does not work either. Is my database router wrong?
