Re: New django 1.0 website: www.astronomy2009.org
Very interesting. Nice work. That scrolling calendar widget near the bottom right of the home page needs a reset button. Once you scroll a bit, it fills up with so many events that finding your way back to today is tough. (Or maybe that thing is supplied by Google and so you are hosed as they almost never fix bugs of that nature.) Fortunately the menus provide access to current events so maybe this SNAFU is ignorable. Also I noticed "The Portal to the Universe" project. Are you guys doing that one? If so, how can I help?

Re: how to setup LDAP authorisation in django/apache.
We rolled our own LDAP authorization. First I created a python module that imported ldap from the python-ldap-2.2.1 package and wrapped in functions that performed authentication and pulled selected data from our corporate LDAP server. Then one of my partners used that to create our own login_required decorator. We wrapped selected application pages with that and used the regular auth system to define a few non- LDAP users who needed to use the Admin. We have been using that for about 2 years. I have a task ahead of me to update this functionality to 1.0. I'll post some notes on that when I am done. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Many-To-Many with extra fields
In my code I have a reference and a name such that I can do perform a "get" to procure the reference to the correct intermediate object. Then I simply interrogate that object directly. It should be possible to do a "values" style query instead if you only want a particular field or set of fields. Hope that helps!

Re: INSTALLED_APPS from a template
I have no idea, but it only took me a few minutes to create a filter
you can put in some templatetags module:
from django import template
from django.conf import settings
from django.template.defaultfilters import stringfilter
register = template.Library()
@register.filter
@stringfilter
def installed(value):
apps = settings.INSTALLED_APPS
if "." in value:
for app in apps:
if app == value:
return True
else:
for app in apps:
fields = app.split(".")
if fields[-1] == value:
return True
return False
Assuming that you named this file "installed.py" then your template
can do this:
{% load installed %}
{% if "django.contrib.sites"|installed %}
and so forth
If the string you supply (or the string yielded by your variable) has
a dot in it ("."), then the full name must match. Otherwise the filter
will just check the last component of the name. (You can edit that out
of the filter if you don't like that behavior.)
{{ "admin"|installed }}

Re: Can I create unique instances of a model to live under another model?
It may be as simple as creating an intermediary field between Document and agency called Study. (See the Django docs regarding adding extra fields to a many-to-many relationship.) In any event, it is wise not to think of models as objects so much as stand-ins for DB tables (which is what they are.) So this should be treated like a schema design problem, not an OO design problem. (Yes I know models can be inherited abstractly and concretely and I take advantage of that in my own code, but that can gt you into trouble if you aren't clear of the limitations that inheriting models imposes.) If you are unclear on the difference between database schema design and OO design, then you might want to consider procuring a consultant to review your schema design in light of your complete set of project requirements at some time point early in the design process. That might save you a ton of time and money in the long run. Rock --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: 'get_latest' is not a valid tag library
Hmmm... Here are some guesses: If that return statement in render is a single doublequote instead of 2 singlequotes, then your code probably won't parse and, even if it does, get_latest certainly won't be found. It seems to me like you need to coerce the string being assigned to self.num as make it an int. (Better yet, put that logic in the parse section.) However that is unlikely to be the cause of the error that you are seeing. You might want to try compiling the code by hand to make sure there are no stray typos. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Dynamically appending a step to FormWizard
I cannot show you the entire code since the company lawyers have not had time to allow me to release this snippet, but I did get this working. However it was not easy and required some interaction with the guys who created FormWizard. My approach was to create a DummyForm which I put in the second slot of the form_list. I also had a dictionary of possible replacement forms which were chosen via a selection on the first form. The critical bit of processing looks like this: def process_step( self, request, form, step ): if step == 0: if form.is_valid(): selection = form.cleaned_data["selection"] self.extra_context["selection"] = selection if self.form_list[1] != self.form_dict[selection]: self.form_list[1] = self.form_dict[selection] The is_valid call forces a reclean of the first form's data each time, but is required since you can't reliably save state data during this process. (Also don't freak out that step == 0 occurs with each iteration through your wizard as you go to subsequent steps.) There may be more challenges after you get across this bridge, so please post a follow up on how this works out for you.

Re: Rendering just child template...
No. Typically you would make a stand-alone template that does not
extend anything else. This template only renders the contents of the
container in question. It can be used by your AJAX view to create an
updated container which can be passed back to the browser. But the
same template can also be included by a child template (or templates)
at the appropriate place to perform the original rendering of that
container on full pages as required. So your child template now
"includes" this same template:
{% include "my_dynamic_container.html" %}
Hope that helps...

Re: page not updating right away
A very common problem is that the timezone or system clock is off. Most Blog implementations allow you to create a blog entry "in the future" so it shows up on your web page only after a specified time. This capability plays havoc with noobies who haven't bothered to set their timezone correctly in their settings.py. A 2 hour delay is the most common since the settings.py defaults to Chicago and many shared host servers are based in the Pacific timezone. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: populating forms using models
In brief, your forms field for province does not have to have anything to do with your corresponding model field. Just make a forms.ChoiceField with the data filled in that you need (or else look up the pattern for loading dynamic data into a forms.ChoiceField and do something like that.) If you go the dynamic route, make sure your form gets initialized properly when you create it for initial use and also when you create it for POST processing. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Django pluggable adressbook/mini-CRM?
I have looked for this myself and in my opinion the answer is no. There are several mini-crm prototypes that were started in pre-1.0 days and abandoned. None of them includes a basic design that I find compelling. The minibooks app is the closest thing to a working Django CRM, but it has several annoying problems that make it unusable in its' current state. Also it combines a CRM and a ledger system in an intertwined manner such that neither the CRM nor the ledger is "pluggable" without the other which, in my book, is not an ideal design.

Re: App for creating "subsites"
First you have to figure out how you want to map your users to their pages. Do you want to use subdomains? How about something like the delicious.com scheme (i.e., http://delicious.com/username/ ) Or perhaps you have something else in mind. After you figure out your URL mapping, the rest looks like standard Django stuff to me. You have your different Django apps and you simply pull data out of each of them on a per user basis. You will need to look into a "paglet" model like django-chunks for managing content from several different Django apps in a single user page. Lot's of people have created their own implementations of this particular capability as it is not difficult to do. The tricky part will be what to do if your site gets popular and suddenly you are managing a ton of data. Then you may need to start using advanced techniques to scale your site. But for now I wouldn't worry about premature optimization. Just keep it simple for now.

Re: Testing dynamic apps
I took a similar path. I cloned the run_tests function from django.tests.simple.py and put it in my project directory as test_setup.py while adding this near the top of the function: if settings.TEST_APPS: settings.INSTALLED_APPS += settings.TEST_APPS That at least allows me to define TEST_APPS in my main settings file for the project and in a location near INSTALLED_APPS so that I am less likely to introduce unintended collisions. But my approach feels dirty too. It shouldn't take much work to incorporate a TEST_APPS construct into the existing test framework. I realize it might be nicer if each batch of unit tests could define their own set of extra test models, but I think that a master list of additional test apps like above has the advantage of simplicity. But I haven't given this a lot of thought beyond this simple minded hack. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: can't pass a parameter to my named url using {% url %} tag in template
I had the same problem recently in a template that was created for use in an inclusion_tag. My workaround was to the perform the reverse call in the templatetag and pass in the resulting url. If that is not an appropriate workaround for you, perhaps a "with" will do the trick. If that doesn't work and you can't figure out how to make this work within the template, then you are going to have to create a custom version of the url templatetag that can handle the variable correctly. This deficiency in the url templatetag may warrant a Django ticket (unless there is already one posted for this scenario.) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Django Training
Steve, I think that the book by Forcier, Bissex and Chun called "Python Web Development with Django" is worth looking at with regards to ideas for a lesson plan. To me it seems that it would be an excellent workbook for a very full week of classes. Their chapter 1 on python and the first few pages of chapter 3 on dynamic web site concepts can be viewed as either a good set of prerequirements or else as required pre- reading for the class. Also note that the book is based on Django 1.0 which makes it unique in this regards at this time. I like their idea of jumping in right away and building a simple project as they do in Chapter 2 and then doubling back and going over the core concepts starting with Part II of Chapter 3 and then Chapters 4, 5 and 6. I think this material could be covered in 2 days worth of classes. After that the book presents a bunch of example projects and advanced concept chapters and appendices that can be used to round out the class. Mix in some hands on exercises and you have a very full week of learning while the book itself makes for a nice take away for the students, Just my thoughts. In case you are wondering, I am not being paid by Addison Wesley to make these comments nor do I know any of the authors. I simply read the book and then decided that if I decided to put together a Django training class that I would probably use the book as the basis for such an offering. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Blueprint css versus YUI grids versus ?
I have generated several static sites using Django aym-cms,
blueprint.css and markdown. This worked so well that I created a
django app that encapsulates blueprint.css so that I now have the
ability to manipulate layouts dynamically. Next up is to hook up
"pagelets" (i.e., django-chunks, django-modular, etc.) to create
sublayout units that I call "gridlets" to boost this stuff into the
realm of end user directed (or at least selected) layouts.

Re: An easier way to do this Pagination in a template?
I would move the logic into a custom filter. This keeps it out of the
view and radically simplifies the template logic. It is easy to create
a filter that takes an argument, so the fact that you have two
inputs (page_number and current_page) is no problem.

Re: Django Tutorial02 / TEMPLATE_DIRS
The templates have to be within a directory named "templates" found in the /var/www/ directory. BUT DON'T PUT TEMPLATES THERE! Put the templates dir in the same directory as your settings.py file and set the path accordingly in the settings.py file. Here is another good alternative: Comment out the filesystem loading option. This means that the second loader (which is the app_directories template loader) will be used exclusively. Now put your templates file within your application directory, i.e., myapp/templates/ and put the templates in there. Now you don't have to specify an absolute path in the settings.py file for template loading. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Template Macros Like In Jinja
You can create an intermediate base class that extends your base class
and includes elements like:
{% if actions %}
... show action table ...
{% endif %}
{% if element %}
... show edit element form ...
{% else %}
... show add element form ...
{% endif %}
and so forth and so on. Now your page appearance is controlled by
whether or not you pass in corresponding data elements.
This is not a true replacement for templates, but it does allow
for consolidation of repeating visual elements across a set of pages.

Unittest test-database not empty
I'm using the unittesting-environment for test-driven-development in Django. It works excellent, but one matter is puzzling. The Django documentation tells me this: "The test database Tests that require a database (namely, model tests) will not use your "real" (production) database. A separate, blank database is created for the tests." However, the test database is not empty after creation, it has two users, which makes my test fail: class MyselfTest(unittest.TestCase): def testNoInitialUsers(self): all_users = User.objects.all() self.assertEqual(0, len(all_users)) The test fails with the message: AssertionError: 0 != 2 When I print the usernames of these users, they are "testuser" and "testuser2". I expect one of two explanations; either I am doing something strange, or the Django-documentation for "Testing Django Applications" is not correct. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Unittest test-database not empty
Thanks Russ, for your helpful comments! I'm now searching for the initial_data fixture. I have looked through all files in this project without success. When I run python manage.py test there is no such sentence as "Loading 'initial_data' fixtures", but maybe there shouldn't be one? I've also looked in all files named initial_data.* on my system without luck. I have a vague memory of creating these users (testuser and testuser2) a long time ago, possibly under another project. Does anybody know how to find (or delete) this fixture that is hiding somewhere?

Re: Unittest test-database not empty
I have no fixtures/initial_data-files anywhere in my project tree! Actually, the only file named "initial_data" on my system is djtrunk/ tests/modeltests/fixtures/fixtures/initial_data.json. And that file doesn't contain much. The "ghost-users" only show up when I'm running "./manage.py test". When I delete the project database and run "./manage.py syncdb" and "./ manage.py runserver" an empty database is created. So I guess my problem has something to do with the unittesting, but it is still magic to me how and when these users are created.

Re: Google App Engine & Django
Brox ... Nice writeup! Many thanks! Now for my thoughts... I have been using PyTables as an adjunct datastore along with the Django ORM for almost a year. To me, BigTable looks a lot like PyTables and, as such, I know that it can be be a great supplement to the Django ORM in certain scenarios. GQL may or may not be a great idea, but I certainly don't think that it is a bad idea as I have had similar thoughts when contemplating improving the integration of PyTables and Django. The key to me is multiple database support. Then we can keep the ORM and also develop a OTM (ObjectTableMapper) perhaps targeting GQL and take advantage of both datastorage models. Plug in a GQL front-end to PyTables and much of the anguish of being tied to the GoogleAppEngine starts to disapate. I guess I will have to review the work that has been going on for multiple DB support and see if it needs to be extended to also include support for multiple model mappers. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Suggestion: Aggregate/Grouping/Calculated methods in Django ORM
I created such a patch last spring during the Django sprint at PyCon. The basic interface was very straightforward but there was also a slightly less straightforward interface option that allowed for grouping and so forth. The patch was discarded, however, since some of the core Django developers wanted to chime in on the interface design for aggregate functions, but felt they didn't have time to do so until after 0.95 was complete. Rather than fight for my design (which I was not particularly passionate about anyway), I just went home and used plain old SQL when I needed aggregates. (I also learned about data bubbles and redesigned my tables to include them as necessary. This redesign eliminated almost all of my needs for an aggregate function interface.) I am still interested in this topic, but I haven't had the personal bandwidth to stay on top of the Django Developer's group. It would be nice to know what, if anything, is happening along these lines. I might even be willing to spend some time on this during the holidays.

Re: Suggestion: Aggregate/Grouping/Calculated methods in Django ORM
Yeah it is all coming back to me. I was unwilling to answer all of
these questions and create the perfect solution (which may not exist)
and therefore we don't have aggregates in Django even though I
demonstrated that a straightforward implementation was possible way
back when. Thanks for backing me up on that Russ. ;)
What I am pondering in the meantime is whether or not to do a fork of
Django someday that concentrates more on scientific presentations
rather than newspapers. In DjangoSci (or perhaps TechnoDjango) there
would be a lot of attention to data reduction, statistical processing,
queries oriented towards returning graphable data sets and, of course,
true floating point data representations in the database. I am willing
to wait for Malcom to finish his work before making this monumental
move. I will also look over SQLAlchemy.
The desire to mold a version of Django (or Django itself) to better
handle the needs of the technical/scientific market does not in any way
represent a slap at Django itself or its' many paid and volunteer
developers. Django rocks! It has become a core capability in my
development group. We already have 3 elaborate and highly visible
internal applications based on Django and our ability to quickly
respond to requests for improvements has changed the dynamics of how
our entire division does much of its work.

Re: Random Data
I wrote a utility to parse a model files as well as embedded comments that provided data loading hints. It was trivial to do. The utility used "cog" to generate a data loading program. That worked like a charm even as the underlying models evolved. (This approach was a "win" since the data loading program was quite complex. We have sinced rewritten the loading utility with python and simplified it to the point where the need to automatically generate the code for the data loader is overkill.) Combining that idea with techniques for generating random data should be easy. The http://agiletesting.blogspot.com/";>Agile Testing Blog" has a recent post about Python Fuzz testing Tools that has some good links regarding the generation and use of random data.

Re: Splitting the databases
This is not quite precise. I use two different databases on a single installation. In fact, using the virtual hosting capability of apache and modpython, I have one set of Django applications uses a PostgreSQL database and an entirely different set of Django applications that use a MySQL database. I am doing this to allow the two sets of applications to use independent processes for backup and restore operations. (The quickest way to backup and restore postgreSQL is to copy the whole "data" area, but using this approach you cannot separately backup and restore two different postgreSQL databases that share that data area.) Fortunately I have no requirement that the two applications share data, user authintification or anything else, but theoreticaly I could do this by writing raw SQL code to get at the "non-settings" database in either of the applications. (Painful, but possible.) Perhaps more accurate would be to say that Django does not allow for easy data access or data management of multiple databases in a single installation. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Caching in Django admin
I can confirm that the odd behavior that you are seeing comes from setting up the global caching for a site. I see the same thing on a site under 0.91 that uses global caching, but not at all on other non-caching sites. (BTW, the work around is to periodically blow away the files *admin* in the cache directory.) It looks like the right way to deal with this is to implement per page caching, but that doesn't look too simple to me. I hope that someone will prove me wrong by posting some simple instructions for implemeting per page caching. Alternatively please post a mechanism for disabling global caching for selected pages (even though I doubt that that is possible without creating some custom middleware.) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Strange 'caching' issue
I forget the details, but this has something to do with your time and/or timezone setup. The default blog app doesn't post items that are set "in the future". The time you set by seleting "now" in the admin may or may not be the time that you think it should be because of the server clock and timezone settings. Something like that anyway. Probably not caching (unless you have enabled site-wide caching, then perhaps that is the problem.) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Database Migration
One of my django apps contains testing data about every item our company has manufactured over the last year or so. The database has over 50 million rows of data. Despite this I have successfully migrated the database several times. Sometimes it is trivial. Back up the data for safety and then just add a column or columns in a table while making the same change in the models. Viola! (Renaming or retyping a column can be similarly easy at times.) I have even done a more massive migration. Here I backed up the data. Cleared out all the tables. Made the model changes and recreated database tables. Then I used sed to edit a copy of the backed up data such that I could reload into the new tables. Django does nothing to make it easier or harder to migrate a database that any other database app (although I hear persistence rumors of some eventual tool support for some of the more trivial migration oeprations.) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Server Error pages
My view code for my calendar app can detect when a user supplies a bad year, month or day, but I have no idea how to get Django to display an application specific "500" page. I put a 500.html in my templates subdir for the calendar app, but it is not found when a raise an exception. It does look elsewhere for a 500 template, but that file doesn't exist in my setup. (In case you are wondering, I set DEBUG = False in my settings.py file.) How is this supposed to work? I saw a mention suggesting changing urls.py and also noticed HTTPResponseServerError, but I haven't found an actual example of application specific error handling. Once I have this working, is there any way for my application to override or bypass the global DEBUG setting so that these handled cases do not yield a traceback?
Re: Django screencast
Nicely done. Really nice actually. Now since you asked for feedback: Perhaps 8 1/2 minutes would have been better as some of the operations toward the end flew by too quickly to easily comprehend. (I know the show seems slow to the producer who knows the content well, but the first time viewer is your key customer and you don't want to leave them in the dust.) Just a few more pauses at key junctures would have been nice. At the very beginning it would be nice to know the precise state of things. (I presume that Django was installed but completely uninitialized, but it would have been nice to be more explicit about that and perhaps to point out which operations were "one time only".) But those are really small nits and the latter could be solved by supplying some accompanying notes to the screencast. Quite impressive really. Rock
Re: Django screencast
"Django" is pronounced correctly in the screencast.
Re: is Django too powerful?
Wrong I think. There are already several Djangoids looking at making a discussion forum together as an open project. I expect there will be plenty of similar activities. The problem is that Django is changing fast right now without regards to backwards compatability. Wait until 1.0 hits and soon thereafter I expect that we will see more app sharing and cooperative development beginning to take place. I should also add that I don't really like many of the stated conventions for creating sharable apps. The insiders at LJO don't follow those conventions and I doubt many others will bother. IMO the area of app deployment needs more attention and perhaps some additional automation support.
forward references
Well this is more of a python question I guess, but here goes. Let's say that I am using the example model from http://www.djangoproject.com/documentation/models/many_to_one/";>this page in the documentation. I decide to add a _pre_delete function to class Reporter that will delete any articles for that Reporter before the Reporter is deleted. Something like this... def _pre_delete( self ): articles = articles.get_list(reporter_id__exact=self.id) for article in articles: article.delete() The problem is that this won't compile since articles is undefined. What is the preferred way to deal with this type of forward reference where the functions in a given class need to call functions defined for a class that is itself defined later on in the same file? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: forward references
Good catch, but this was just an example to show the poblem I was facing. FWIW, if someone really wanted to implement _pre_delete for Reporter as discussed, they should add this version of the function to class Reporter: def _pre_delete( self ): for article in self.get_article_list(): article.delete() --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: adding page
Mary,
In your templates directory you need a template named default.html.
Here is what mine looks like:

{{ flatpage.content }}

numeric formatting
Is there a template filter for turning a large integer into a human readable number? 1234567 --> 1,234,567 12345 --> 12,345 I don't think that python built-in formatting can do this. (Am I wrong?)

urls.py changes ignored
I have a development site where I can update myproject.urls.py and the changes are acted upon immediately by my server. I just cloned this site onto another computer and everything seems to be in order except that on this new system, changes to urls.py are entirely ignored. Nothing I do seems to be able to convince the system that I have changed the urls.py file. Both systems are running with Apache2 and mod_python on Linux. Things I have tried: Adding NO_CACHE = True to settings.py. touch myproject/urls.py checked the permissions of myproject/urls.py Even removing myproject/urls.py makes no difference in the operation of the clone system. I am using 0.91 for this project. What else should I be looking at? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: urls.py changes ignored
Yes I did. No help. Then I forced the creation of a new urls.pyc by importing urls.py in "python manage.py shell" and importing urls.py and explicitly checking that the correct number of urlpatterns were defined. Still no joy in the browser though. Note that the access_log shows my request but the error_log logs no associated errors. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: urls.py changes ignored
On my development machine I do not have to restart the webserver to have the changes enforced. In any event, I have tried restarting the webserver and also dumping the cache in my browsers without effect. There is no reason to suspect an error with the cloned urls.py file as it is an exact copy of the version on the development machine. Another thing that I have checked is the timezone and tod settings on the two machines and the timezone setting in the settings.py file. I am going to take a deeper dive into the http configurations now. Rock --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: urls.py changes ignored
I found a tiny difference in the http.conf files (AllowOveride was set to "FileInfo" instead of "None".) I made that change, even though I seriously doubted that it would make a difference. Then I bounced apache and amazingly enough the new urls.py showed up. I set the AllowOverride setting back to FileInfo and changed the urls.py again and so forth and proved to myself that the AllowOveride setting had nothing to do with anythng. It was all about the bounce. (Apparently I thought I had bounced the server previously, but had not. Perhaps I was not su when I did the previous bounces.) So now I can force the urls.py changes to be respected by bouncing the server. (Whew!) But that still begs the question -- why is my development server picking up urls.py changes right away while my clone machine requires a server bounce.

Re: create models from the admin page?
falcon wrote: > I still believe that > many 'developers' could benefit from defining simple to moderately > complex models on the web. If code needs to get more complex, > developers can just switch back to using models.py. > I have gone in a different direction. I have written a tool to parse the models file and use that info (along with some hints that I embed in comments) to generate rules to drive pre-existing data extraction software. I then use the same info to generate code that takes the results of the data extraction process and loads it into the Django database. (The loader runs continuously as I manage data coming in from factories that run 24/7/365 at several locations around the globe.) I am still proving this stuff out and tuning performance, but the early experiements have worked out well. I am contemplating the possibility of recasting this code into a mini-framework that could conceivably be contributed to the Django project in the future. My other challenge, which is only partially implemented at this moment, is automating the cloning process. Before I change my models using the tools above, I want to clone my existing Django system to another server (database and all) so that my users can keep using a static snapshot of my system even as I reload the factory data and create new views for the newly added model fields. Ideally I would also configure Apache to send the user to the right server depending on the state of the main system. Fun stuff, eh?

Integrating Admin and Polls Applications
I want to take forward the application creating experience with django, by integrating the polls and admin applications. As far as my knowledge is concerned in the polls appl we developed anyone could enter the url and cast their vote. I wish if we could integrate the admin apppl, and allow only registered users to cast thier vote. Please let me know if anyone has tried this thing before. Would be encouraging for me to get started.

the following code does not work , i also tried Manager with raw SQL, but i
dont' know how to pass the candidatePois to manager, can i get the string
value of "candidatePois" in model ?
class UserStays(models.Model):
startTime = models.IntegerField('startTime', max_length=255)
candidatePois = models.CharField('CharField', max_length=255)

Newbie questions
I have installed django on dreamhost using fcgi. The posted instructions
needed updating due to the improved handlings of settings.py, but I
think I nailed the changes as the admin app comes up fine. My questions:
1) The url '' leads to a 404 error. Is that expected? It is unclear from
the docs what to expect for this case.
(Note that before I modified the rewrite rules, the url of '' was
causing a django crash in the line of code that attempted to add a slash
('/') to the url. This is not a good thing for a newbie to experience!
Perhaps that code should check for and handle len(url) == 0 explicitly?)
2) The admin page has a link to "example.com" which apparently is coming
from the site table. The admin app apparently supports no capability to
update that row. What are the ramifications of directly updating that
row in the site table?
What should I have done during installation to have the correct site
info placed in the db?
