[Error] Mixing Two databases
Hi all,
I am trying to use two database for my django(Django nonrel 1.3.1)
project. One is Postgres and other is MongoDB.
After filling in details in settings.py :
DATABASES = {
'default': {
'ENGINE': 'django_mongodb_engine', # Add
'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'.
'NAME': 'Mongo_MSTR', # Or path to
database file if using sqlite3.
'USER': '', # Not used with sqlite3.
'PASSWORD': '', # Not used with sqlite3.
'HOST': '', # Set to empty string for
localhost. Not used with sqlite3.
'PORT': '', # Set to empty string for
default. Not used with sqlite3.
},
'geodata': {
'ENGINE': 'django.contrib.gis.db.backends.postgis', # Add
'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'.
'NAME': 'mydatabase', # Or path to
database file if using sqlite3.
'USER': 'Username', # Not used with sqlite3.
'PASSWORD': 'Password', # Not used with sqlite3.
'HOST': '', # Set to empty string for
localhost. Not used with sqlite3.
'PORT': '', # Set to empty string for
default. Not used with sqlite3.
}
}
Now if I am doing a
$ Python manage.py syncdb --database=geodata
I am getting a error like this :
django.db.utils.DatabaseError: Ordering can't span tables on
non-relational backends
If however I am executing the above without postgres service started,
I will get a error related to Postgres.
If I am explicitly mentioning the RDMS why is it throwing me error
based on MongoDB?
What am I missing here? Any pointers or documents will be of great help.

I am trying to setup Geodjango over postgres. Since I am explicitly mentioning my model to use postgres and not mongoDB. I thought I had clear shot. but that is not the case and might be the cause of the problem. So how do I handle the settings now? Any Ideas and pointers would help. - Regards Subhodip Biswas GPG key : FAEA34AB Server : pgp.mit.edu http://subhodipbiswas.wordpress.com http:/www.fedoraproject.org/wiki/SubhodipBiswas -- You received this message because you are subscribed to the Google Groups "Django users" group.

Django Userena Problem
Hi all,
I am using Django-userena for my registration process. I made a
custome model in a app called 'users'. However since custom model is
not handled by syncdb, I am using south. I tried to migrate but got
this error instead.
django.db.utils.DatabaseError: relation "users_userprofile" already exists
however when I am trying to signin into my system, I am getting this error
relation "users_profile" does not exist
I guess I am missing something out here, Any kind of help/pointers or
docs will be of great use.
My models.py looks something like this :
class Profile(models.Model):
GENDER_CHOICES =(
(1, _('Male')),
(2, _('Female')),
)
user = models.OneToOneField(User,
unique=True,
verbose_name =('user'),
related_name = 'profile')
gender = models.PositiveSmallIntegerField(_('gender'),
choices=GENDER_CHOICES,
blank = True,
null=True)
website = models.URLField(_('website'), blank=True, verify_exists=True)
location = models.CharField(_('location'), max_length=255, blank=True)
birth_date = models.DateField(_('birth date'), blank=True, null=True)
about_me = models.TextField(_('about me'), blank = True)
@property
def age(self):
some operations
def create_user_profile(sender, instance, created, **kwargs):
if created:
Profile.objects.create(user=instance)
post_save.connect(create_user_profile, sender=User)

Re: Django Userena Problem
Hi all, I kind of got over with the last problem but got stuck in step after that. The previous problem was solved by naming the model to the first one, Since that table was already created django refused to create the same table structure against different name whatsoever. However now, once past sign in or signup forms, when it comes to fetch the profile using get_profiles(). I am getting a SiteProfileNotAvailable error for already existing accounts but no profile and UserProfile matching query does not exist. while for new signups I get a 'UserProfile' object has no attribute 'can_view_profile' Documentation says the AUTH_PROFILE_MODULE should point to appName.ModelName and it is okay in my case. users.UserProfile.

querying data from Django userena profile.
Hi all, I have defined my custom signupform as shown here. http://docs.django-userena.org/en/latest/faq.html I now want to query my custom defined profile as shown above and retrieve a data(first_name) while the user is signed in. Once he signs out that data is flushed out. I see that with User profile, I can do a request.user.get_profile.first_name in the template to retrieve the first name. How do I do that in the views.py. Any solution or pointer towards this in Django-Userena will be very helpful. - Regards Subhodip Biswas GPG key : FAEA34AB Server : pgp.mit.edu http://subhodipbiswas.wordpress.com http:/www.fedoraproject.org/wiki/SubhodipBiswas -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: querying data from Django userena profile.
Hi all, I have done a workaround the initial problem, all i did was add the custom field into my apps models.py. This led to the data entered in the custom field of signup form is shown in the edit_details page of the user profile. However, unlike other data fields in edit_profile, this custom field is not visible in view profile page. Can anybody explain why is this happening and any workaround for this? - Regards Subhodip Biswas GPG key : FAEA34AB Server : pgp.mit.edu http://subhodipbiswas.wordpress.com http:/www.fedoraproject.org/wiki/SubhodipBiswas -- You received this message because you are subscribed to the Google Groups "Django users" group.

Datastructure using django.
Hi all, I am trying to implement a tree structure using django. There are two packages I am looking at mptt and treebeard. Treebeard seems easy. I have however two questions: 1. With mptt I found that if you have moved one child to another parent both db and instance is updated but you need to reload or reregister every time you call such action.Is there a better way of doing this? 2. If my child have more than one parent, the structure does not remain a tree anymore. It becomes a graph i guess, How do you handle such situation. 3. How do I add treebeard or mptt into django admin. If I have one field name and I register it in admin.py. I get error regarding depth,path, numchild and name should be present. How do I handle this situation. Apologies for asking so many questions. - Regards Subhodip Biswas GPG key : FAEA34AB Server : pgp.mit.edu http://subhodipbiswas.wordpress.com http:/www.fedoraproject.org/wiki/SubhodipBiswas -- You received this message because you are subscribed to the Google Groups "Django users" group.
