How can we improve performance in the Admin when loading profile pages with ManyToMany fields?
We have five or so ManyToMany fields (with 10,000+ and growing total entires in each field, only a few are selected for any one profile) in our user profile. When we bring up the profile in the admin, the page takes a while to load and render and taxes django and the database more than we would like as admin loads all the field possibilities. Most of the time we use the admin to view the data, not make changes. Is there anything we can do to improve performance? -- Eric Chamberlain --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Has anyone used the django database as a backend for openldap?
Hi, We have various servers and tools that can use LDAP for users, groups, and authentication. The users and groups information we would like to use is in django. Has anyone used the django database as a slapd backend?

If your app servers have access to the password decryption keys, then anyone with access to the app server also has access to the password decryption keys. The simplest solution is to use SSL to secure the traffic between the browser and the app server and some custom model methods to symmetrically (AES, twofish, or blowfish) encrypt and decrypt the data going into and out of the database. That would protect you against sniffing and a database compromise, but not an app server compromise. A more secure way to mitigate the risk, would be to split up functions, so public Internet facing app servers do not perform decryption functions or work with plaintext passwords. In that scenario, you could use an asymmetric key (ideally one per user or encrypted password) at the browser to encrypt the passwords. Secured backend servers would perform the asymmetric decryption and plaintext password handling functions. You still have problems if the backend servers are compromised, but they would be much easier to lock-down and audit. -- Eric Chamberlain, Founder RF.com - http://RF.com/ --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

We are after user information and a user can have 0 or more
ProviderAccounts.
The template looks like:
{% for profile in profiles %}
{{profile.user.email}}
{{profile.user.first_name}} {{profile.user.last_name}}
{{profile.user.date_joined|date:"Y M d H:i" }}
{% for calling_service in profile.provider_list %}
{{calling_service.name}}{% if not forloop.last %}{% endif %}
{% endfor %}
{% for sim in profile.sims.all %}
{{sim.caller_id}}{% if not forloop.last %}{% endif %}
{% endfor %}
{{profile.call_count}}
{% endfor %}

How can child objects inherit data from parents?
Hello, We're not sure how can we represent the following data structure in the django model? Grandparent Object First Name - NULL Last Name - NULL City - Anytown Ancestor Object - NULL Parent Object First Name - Bob Last Name - Smith City - NULL Ancestor Object - Grandparent Child Object First Name - Jill Last Name - NULL City - NULL Ancestor Object - Parent We'd like to be able to use the child object with the NULL fields coming from the ancestor objects. We need to update the parent field and have all the child objects return the new value. The parent object behaves like a template, some users have write access to the child, but not the parent object or some users may not have write access to all the child fields. We'd like to keep database calls to a minimum and avoid looping lookups if possible. Is there a better way to implement this? -- Eric Chamberlain -- You received this message because you are subscribed to the Google Groups "Django users" group.

Trying to limit a ForeignKey in the admin site, but formfield_for_foreignkey isn't working
How do I get the default_provider field to only list providers that belong to
this Partner?
class Partner(Model):
id = UUIDField(primary_key=True)
...
default_provider = ForeignKey('Provider', null=True, blank=True)
providers = ManyToManyField('Provider', related_name='provider_partners',
blank=True, null=True)
class PartnerAdmin(ModelAdmin):
list_display = ('name', 'type', 'url')
list_filter = ('type',)
exclude = ['calls','providers' ]
raw_id_fields = ('admins',)
inlines = [ PartnerRegistrationInline, ]
def formfield_for_foreignkey(self, db_field, request, **kwargs):
if db_field.name == "default_provider":
kwargs["queryset"] = self.model.providers.all()
return db_field.formfield(**kwargs)
return super(PartnerAdmin, self).formfield_for_foreignkey(db_field,
request, **kwargs)
The code above generates an AttributeError:
'ReverseManyRelatedObjectsDescriptor' object has no attribute 'all'

Re: django takes all my toys
It sounds like Django is working and your issue is with the web server configuration. In you case it sounds like there are two ways you could install Django, add a virtual host to the machine, or configure apache to serve Django from a subdirectory. Unless you have extra hostnames available, I'd go with the subdirectory option. Both configuration options have examples on the web.

Re: group password
I would use auth.User as is. When a new user (no existing django session) enters the code, django creates a user account (random username and password) behind the scenes and logs in the user. Then the user is identifiable as long as they stay on that machine. Set the logout interval to whatever you need for the experiment duration.

Re: If is first time logging in
Anything wrong with adding a flag to the profile model? If the flag is not set, show the profile stuff? It keeps all the profile management in one model. The "flag" could even be a timestamp, so you could show the prompt again, if after X time the user has not added anything to their profile.

New project, debating postgresql or MySQL (Amazon RDS), does it matter to Django?
Hello, We have a new project and are debating whether to use postrgresql (Amazon EC2) or MySQL with InnoDB tables (Amazon RDS). It looks like our TCO would be much lower using Amazon RDS. Our past Django experience has been with postgresql, does MySQL InnoDB have any problems with Django's transaction middleware? We aren't using any custom fields, are there functional differences between the two databases that would impact how we use Django? -- Eric Chamberlain -- You received this message because you are subscribed to the Google Groups "Django users" group.

Indexing large CharFields with MySQL backend
Hello, In our model, we need to do lookups based on the user's XMPP JID. The JID can be up to 3071 characters long. The problem we have run into is that MySQL does not like to index columns that are that large. We are working on an implementation where we generate a hash and index the hash value, but we were wondering if anyone has already created a model field that addresses this problem and makes the database limitations transparent. -- Eric Chamberlain -- You received this message because you are subscribed to the Google Groups "Django users" group.

In some cases, we generate a random 30-character username, the odds of a collision are very low and we don't run into issues trying to truncate an email address so it will conform to the username field character and length requirements. In other cases, where we need a deterministic username, we base64 encode a UUID for the username. We try to not tie the username to a derivative of the email address, so we can avoid username collisions if the user changes their email address.

Trying to implement a unique default relationship between models
Hello,
I'm trying to implement a default relationship between models.
Each otherApp.Partner model can have zero or more Registration models.
One Registration per otherApp.Partner can be flagged as the default
(default_reg).
What I would like is for the default_reg boolean to be configurable from the
Admin. I've written up the code below. Save properly updates the other
Relationships, but the Admin form validation won't allow (unique error) another
Registration to be set as the default, until the first Registration is
unflagged.
How do I override the form validation or have it ignore the unique constraint,
because it is handled in the model save method?
Or is there a better way to do this?
class BasePartnerModel(BaseRFModel):
""" Adds the partner key to the model. """
partner = ForeignKey('otherApp.Partner')
class Meta:
abstract = True
class Registration(BasePartnerModel):
""" When a user registers with us before registering with a partner, we
need to send the
user's information to the partner. This model tracks where to send the
registration
information, and maps the results between the partner and us."""
# TrueNoneField from http://www.djangosnippets.org/snippets/1831/
default_reg =
TrueNoneField(default=None,verbose_name=_('default'),help_text=_('Default
registration if one is not specifed, if no default, first one is used.'))
def save(self, force_insert=False, force_update=False):
if self.default_reg is True:
# if this is the new default, set others to False
Registration.objects.filter(partner=self.partner).exclude(pk=self.pk).update(default_reg=None)
super(Registration, self).save(force_insert, force_update) # Call the
"real" save() method.
class Meta:
unique_together = (('partner','default_reg'),)

For security reasons unique to our application, we don't have the model decrypt the passwords. Our backend pulls the encrypted password from Django and it decrypts the password before use. We use asymmetric encryption, so a compromise of our web servers and our database servers can not result in decryption of all the stored passwords. In our case, we deal with something of more value than Photographs. If you're only dealing with photographs; not personally identifiable information, credit card numbers, or medical information, I would use symmetric encryption as some of the other posters have mentioned. I wouldn't worry about getting sued, what kind of damages would people have and your EULA should already limit your liability. -- Eric Chamberlain -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Which Linux distro to use on EC2?
For stock web serving stuff, like what you list, we use the Amazon Linux AMI. Amazon handles the optimization and compatibility issues and they are pretty responsive about adding new packages to the distribution. For more specialized applications (VoIP infrastructure, XMPP server), where Amazon doesn't have packages already in the distro we use CentOS.

Re: using django on a server?
Cloud computing is basically resources that you don't have to pay for when you don't use them and no long-term commitments. We use Amazon Web Services and can change our setup on an hourly basis. We just finished consolidating some low utilization servers with Amazon EC2. We cut our costs down to about $.035/hr. And we really like that we can turn on and off development/testing servers and only pay for them when we need them, those are currently running about $.007/hr. We also leverage Amazon to serve our static files (javascript, image & css) from S3 and CloudFront. That traffic doesn't even hit our servers.

It's not free, but we use Amazon EC2. It's like having vmware, but you don't have to manage the host box.

Re: Generate a unique username for django.contrib.auth
Because the id is not known until after the record is saved, so you'd have to generate some non-colliding filler value anyway. Using incremental numbers can also leak usage information to the users.

Re: Django + CSS
Unless you are trying to serve your CSS inline, which it doesn't appear to be
the case from your post, why wouldn't you serve your CSS files like any other
static file? Serve the static file with your web server or CDN and put the url
in the template, no magic required.

Re: Storing *big* texts in db fields
Karen, In your use case, large text fields shouldn't be a problem. I would install the django-toolbar and use the reporting to determine if a particular query or template is causing the slowdown. Are you displaying the large text field in the admin list view? If you are and the view template is using a table, the browser won't display the table until all the data is rendered, that could be the cause of your slowness.

Re: Database synchronization with sometimes-connected mobile client
We had to work through similar issues with our iPhone and iPad applications. We wanted to decouple the server development from the iOS applications and decided to not try and mirror the device and server database schemas, we pass objects back and forth and let each implementation store the underlying object however it needs to (CoreData or SQL). Our object tracking is loosely based on Active Directory's multi-master replication model. We track objects by UUID and last modified timestamp. The device(s) can then pull/push all the moves/adds/changes since the last sync. On Feb 5, 2011, at 5:02 AM, Greg Humphreys wrote: > Hi everyone.

Re: How should I properly impliment HTTP(S) auth (REMOTE_AUTH) in django?
I wouldn't consider using a UUID as multi-factor authentication. All our API traffic is over https. We use the basic authentication included with django-piston. Any reason why you want to exchange username and password for an API Key? Why not just authenticate each request with username and password?

If you have lots of rows, this query is really slow as the db must build a new
table for the ORDER BY.
