FYI - Django, Python-memcached and memcached saves the day!
This post is kind of like a discussion rather than a question.. You can think of it as a feedback if you like (we've solved the issue at hand though would like to know how other people solved similar issue). Anyway onto the point - We needed a way to cache data from our Templates so the way we thought about it initially was to implement flyweight and then have a pool through which we use dicts to get values in/out. It was all good till soonish we figured we couldn't cache a pool of Class objects within each user session (given each HTTP request is distinct) within our classes. Cookies for anyone who can tell me how they solved the problem without using any kind of serialized/non-serialized persistance (the whole point was _not_ to hit the DB again and again if same data was being asked) :-) The way we initially tried was this- 1] Time t1 HTTP/1.1 Get => Django View => flyweight impl => pool(k) => Get v for k or create a new one and return it. 2] Time t2 how would this one work out? HTTP/1.1 Get => Django View => flyweight impl => pool(k) => Get v for k or create a new one and return it. There is no way flyweight class would know the difference of t1 from t2 because it doesn't have whole view of the system and it will just keep creating a new Pool for each seperate request. Unless, we use in-memory persistance, this thing wouldn't work yeah? Or, is our design flawed (constructive critcism welcomed :-) After a bit of discussion, we used memcached which solved the issue beautifully as such: 1] Time t1 HTTP/1.1 Get => Django View => flyweight impl => memcahed_pool(k) => Get v for k or create a new one and return it. 2] Time t2 Now it works HTTP/1.1 Get => Django View => flyweight impl => memcached_pool(k) => Get v for k or create a new one and return it.

No, I was thinking in Django applications - actually in web applications in general, since I'm not convinced yet Django is the right tool for the job, but it's project vs application design is exactly how I had it in mind. It's a little more complicated by the fact, that some datasets are related, but not necessarily the same, as is the case with available geodata per region (different providers use different names for the same meta-data, though I may need to pre process and standardize it for my own sanity). > The reason this matters is each Django project connects to PostgreSQL > as a single user, so any role-based authentication will be uniform > across everything inside of that project.

So, if I gather this correctly, anything Django's project user can see, it will try to model and manage on syncdb. Am I correct in assuming that it's unique project ID, filters data in a given application, so that for instance user Bob can exist both in project X and Y, be different, but stored in the same auth.users table? Also, if inter-schema foreign keys already exist, will this confuse Django? At first glance it seems that the 'Application.field' syntax for the ForeignKey method introduces a few problems, unless I strictly adhere to the "Django Application equals PostgreSQL Schema" design. -- Melvyn Sopacua -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Auth and Sites in Admin
Great, thanks. That solves my problem. But, I wish it were possible to actually make a user read only. Unless I give the user the right to change content the admin page says, "You don't have permission to edit anything" and no content is visible. But overall, I think admin is really great tool and there is still a lot to learn.

Quoting the documentation: http://docs.djangoproject.com/en/dev/ref/django-admin/#syncdb "Syncdb will not alter existing tables syncdb will only create tables for models which have not yet been installed. It will never issue ALTER TABLE statements to match changes made to a model class after installation.

Re: Making the case for Django (vs. Drupal)
Hi, new to the list here, but I've been doing Django dev for a while now and Drupal as well. In fact, at my workplace (60-person web design/ development shop) I'm leading a similar charge to move us away from Drupal development towards Django. I took a look at your post and thought I'd add a few things: 1. It's not exactly correct to say Drupal isn't Object Oriented. Like Django, some of Drupal is written in a typical procedural style, some OOP. It's more accurate to say Drupal is less Object Oriented. More here: http://drupal.org/node/547518 In any case I'm not sure it's a huge selling point. 2. Same for MVC: Drupal does it...kinda. More here: http://archivemati.ca/2006/01/21/drupal-as-a-mvc-framework/ I'd say Django maintains a separation of concerns much better, though, and I'd say this is a big selling point, unlike OOP 3. +10 on templates: Drupal templates are very frustrating. A single page is usually generated by an elaborate nesting of templates. Let's say you have a page that lists a bunch of nodes. You have a template for the page, for the list, for node itself and maybe (with CCK) individual node fields. This is a lot to keep track of and why there are whole books written about Drupal templating. What's more, you don't have enough control over markup. A lot of devs where I work feel very frustrated when the lean, clean, semantic html mockups they produce get completely torn up by the way Drupal works. Django almost never forces any markup constraints on you. This allows front end dev to proceed more or less parallel with back-end dev in Django, which buys you a lot of time if you have teams that work that way. In Drupal, the templating phase is intimately tied into the back end development phase, partly because of the less-than-stellar separation of concerns mentioned in #2 above. That's a slower way to work. 4. Drupal doesn't have an ORM, really. With you can get a mapping of DB fields to a php object, so that say, the "title" DB column maps to an object : $node->title, but that's not really an ORM in any sense that I think of it. 5. Security. Django makes a lot of design decisions that make it hard to write insecure code. Not impossible, but hard. Some attack vectors, like SQL injection (and other input sanitization exploits) are pretty much eliminated by Python's DB API and Django's ORM and Form validation tools. This is not to say you couldn't create an exploit in a Django app, but that you'd have to be trying to on purpose. They also give you tools to prevent CSRF which were optional, but in newer releases are being promoted to "required" in contrib.admin at least (http://docs.djangoproject.com/en/dev/ref/contrib/csrf/ ) One of PHPs biggest failings re: security , IMHO, is they made it too easy to do the wrong thing for far too long. This is improving, but I think you still see this lax approach reflected in the large number of Drupal exploits that have appeared and in the way many people don't seem to take security as seriously in the PHP universe. 6. Deployment. I tend to think of Deployment as more than just installing an app and for that reason, I think Drupal's deployment is far inferior to Django's. It's relatively easy to set up a Lamp stack and install Drupal on it. Django requires you to install Python, Apache, your RDBMs, python drivers to connect to it, PIL (probably) and mod_wsgi (Hopefully that's what you're using). These things represent the baseline for installing an app, IMHO, and for people without a *nix background, setting them up is harder than in Drupal (although with debian and dpgk, it's not that bad). But to me, deployment means more than installing a LAMP stack. Deployment means packaging. PHP doesn't really have good package management tools. Python does. Deployment means being able to run a test suite on your install and know immediately if anything has broken: Django let's you write tests for your app, Drupal does not. Deployment means being able to maintain dev, staging and production environments in sync. In Drupal this is very hard: one of my biggest complaints is that Drupal is that it mixes application configuration and data in the DB so that they are completely inextricable. This is a huge problem if, for example, you want to migrate some new views from your staging environment to your production environment. Deployment also means upgrading: In Drupal you've got the upgrade treadmill and it sucks. The more modules you have the more it sucks. Upgrades not infrequently break things, and since you have no unit tests or functional tests, there's no way to know if something broke without clicking around and hoping you catch the problem. Django + Python give you: + package management (distutils, virtual_env, zc.buildout) + unit and functional tests + fabric to help deploy in multiple environments across the cluster + south to help you migrate schemas + a complete separation of data from everything else My argument against Drupal boils down to 2

It does not sound logical. I don't think that anyone is seriously arguing that a piece of software being widely adopted somehow creates new security vulnerabilities in it. I believe the assumption is that all software of a given level of complexity has roughly the same number of vulnerabilities, either exposed or hidden. Thus, the more used a piece of software, the more attention the bad guys give it, and thus the more of those hidden security problems become exposed. -- -- Christophe Pettus x...@thebuild.com -- You received this message because you are subscribed to the Google Groups "Django users" group.

That's a tricky area - we have to be very careful about saying that anything is "more secure" than anything else. We don't want to give false hopes/impressions to managers, and we have to remember that part of the reason for Django's security track record is because it's "below the radar" of attackers.

That's really a function of the designer's skill set.

First, it's important to be sure we know what you mean by "application." In Django terminology, an application is a sub- component of a project; a project corresponds to what many people mean when they say "web application." The reason this matters is each Django project connects to PostgreSQL as a single user, so any role-based authentication will be uniform across everything inside of that project. If each of the "applications" you are talking about are a different Django project, you can have each connect as a different user with different PostgreSQL permissions. Assuming that you are able to use role-based permissions, you can set each user to have its own schema search path, and thus make visible to each user only the schemas that you want that particular user to see. Django does not, right now, have the ability to qualify table references with schemas, so the search path is the only practical method for using multiple schemas with Django. -- -- Christophe Pettus x...@thebuild.com -- You received this message because you are subscribed to the Google Groups "Django users" group.

What would cause an app to not register?
Howdy Everyone! After having installed a fresh version of Pinax 0.7.1, I have an interesting problem with the behavior of Django when I try to install custom applications. In my main project directory, I've created an 'apps' directory, and created some standard django skeleton apps. When I tried to run 'syncdb', I noticed the tables were not created for my models. After some amount of tracing, I found out that Django is not registering my apps, with my models. With skeleton models the apps register fine. When I say 'register', I mean this: I detect if an app is registered or not by doing this in manage.py: from django.db import models myApps = models.get_apps() I then look through the myApps list to see if my apps are present. I note that all of the Pinax apps are always present. Here is an example. This model causes the app to not register: --- from django.conf import settings from django.contrib.gis.db import models from django.contrib.localflavor.us.models import USStateField class Zipcode(models.Model): code = models.CharField(max_length=10) poly = models.PolygonField() objects = models.GeoManager() class Address(models.Model): addrKey = models.CharField(max_length=32) num = models.IntegerField() street = models.CharField(max_length=128) city = models.CharField(max_length=64) state = USStateField() zipcode = models.ForeignKey(Zipcode) objects = models.GeoManager() - This code allows the app to register: from django.db import models Has anyone seen this before?

The job of a django web designer
Hello, I am new to django and I am having a little issue in understanding the expected role of a designer during the development a django website. Is the point of the django template system to allow a designer to not have to worry about any code, and only need to deliver let's say, a pure html+css template to a coder who in turn will input the whole blocks and logic into that template? or is the designer expected to learn the django template system?

PostgreSQL Schema support
Hi, I'm considering Django for some projects, but initial research on schema support only showed some generics and I can't really find a good answer to my specific situation. So, I figured I'd try here. I've developed a database which should support various applications, separated by schema's. For sake of this discussion let's consider the following: PostgreSQL | |-- DB:webapps \ |-- schema:geo_regionX |-- schema:geo_regionY |-- schema:domino |-- schema:appointments |-- schema:salesforce |-- schema:auth |-- Other dbs The appointments application for client X needs access to geo_regionX. The salesforce application for client Y needs access to geo_regionY. The domino game needs access to neither. All need access to auth. Appropriate security measures have been taken in pg_hba.conf to enforce these permissions on connect. So my question should be obvious: Is it possible for a "Django appointments application" to understand and use the geographical information from the tables in the geo_regionX schema and equally important to treat that specific schema as read only, as the data is kept up-to-date by other means? -- Melvyn Sopacua -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Confirm email by matching on form
In addition to the above, cleaning that requires two fields is best
put in the forms overall clean method. This makes it a bit harder
because you can't raise a validation error if you want the error to
appear by the field, you have to insert it into self._errors.
Also, I have an even simpler suggestion. Don't make the user confirm
their email. I'm getting fed up with seeing this on forms all over the
web when it serves no purpose at all. You confirm a password because
you can't read it back. You don't ask them to confirm every other
field do you?

But template tags should be used for template objects that require filtering or displaying context objects not specifically associated with the view. If you want the car object to go through this choice in many different views, you'll want a template tag, but if it's only in one view method, you should do it in the method. For good examples on how/when to use custom template tags look at the comments framework or csrf one. The comment framework example is good because that application can be attached to any model and added to any view, so in this case you want it as a template tag.

Stucked in template language
Hi there, we have models like this: 1. A car database with freely assignable attributes. 2. An attribute-type table (ex: color, engine, seats) 3. Car attributes (ex: color:red, seats: 5) variable car by car We have to display a matrix of cars (rows) with different attributes (columns), but not every attribute is assigned to every car (empty cell in the table), columns are flexible...so if at least one car has a 'seats' attribute, there will be such column. In the template i cannot decide if specific attribute is assigned to a car or not, because i cant pass parameter to method call. How can i override this?

This means that the sorting algorithm used is not a stable sorting algorithm. Does anyone know how to go about making the admin interface use a stable sorting algorithm instead? I'm capable of implementing a stable sorting algorithm in Javascript, but don't know where to start to find the code that actually performs the sorting when I click on a column in the list view.

Not related to your problem, but storing two copies of the (verified to be
the same) email address in the database seems odd. I would leave email_conf
out of the model and include it only in the form.

I'd guess the problem is here, where you are returning the entire
cleaned_data array instead of just the data for the field you are cleaning.

I should say that I am using Django 1.1.1, Python 2.5 and sqlite3.
Thanks for your help.

Django/GoDaddy
I recently took on a new project for a new client where I was forced into using a GoDaddy Virtual Server (literally it was a deal breaker). Anyway I have configured about 1/2 dozen servers to run django - but I am stumped on this. I am looking for help from anyone who may have this experience. Server: CentOS 5 Python 1.4 Django 1.1.1 1. mod_wsgi was not available so I tried to compile from source. The apache apsx was not available and other attempts to config failed. I grabbed the apache source-dev to get the apsx, but the config failed. No problem I moved on to mod_python 2. Attempted to launch the app and got an error that there was no pysqlite2, they had the previous version. I pulled the latest version but again had failed at config. I moved to mysql and again the version that was available on yum was too old and trying to compile by the newer version failed at config. Their technical support person was mean and less helpful than a sharp stick. In short: I can't compile any of the necessary components, all of the yum updates are too old. My only other options for server are Cent OS 4 and Fedora Core 7 (I come from the Debian World mostly). Any recommendations? -- You received this message because you are subscribed to the Google Groups "Django users" group. To post to this group, send email to django-us...@googlegroups.com.

Re: Mediatemple/Django
I looked at it, but at the time they charged $20 for the and then $20 for the container with metered GPU. FOr $50 a month I got their equivalent of a virtual dedicated with unmetered GPU (they still watch bandwidth etc) which worked out really well.

Re: Increment a value in a database table field
Exactly Karen the model is confusing. Here is the exactly model.
class Resource_Track(models.Model)
users = models.ForeignKey(User)
resources = models.ForeignKey(Resource)
date_tracked = models.DateTimeField('Date Tracked')
description = models.TextField()
status_count_per_week = models.IntegerField()
status = models.ForeignKey(Status)
class Meta:
verbose_name_plural = 'Track Resources'
Sorry for confusing you.
