This really is brilliant. One of the biggest hurdles the company I work for have faced with Django is actually selling it to clients due to how relatively unknown it is. I've honestly never heard of Alfresco before but looking at their client base this is just the kinda thing we need to pitch Django at an "enterprise" (I just threw up a little) level.

Alfresco is very loving cool, because it lets you automate business processes and do things like hook up with an ISO quality consultant or whatever and implement paper trail management and poo poo like that.

If you get into the workflows part of it, it starts to get really cool. Someone goes into word, fills in an order request, publishes it into an alfresco folder using words sharepoint interface, the thing then automatically forwards it to your manager, who reviews, ticks off, then fires a pair of copies into the purchases and engineering, meanwhile your customer logs into your django based portal (all authenticating from the same AD source) , reviews progress, and possibly adds a comment.

And you could impement that poo poo in a couple of days.

Double points if you replace the customers shared drives with the alfresco repository (It has a samba interface) , and start porting their ad-hoc internal processes into proper business flows.

Alfresco is serious enterprise poo poo, and it isn't microsoft, so theres geek cred right there.

Theres nothing it can do that sharepoint can't also do, and theres probably a few things sharepoint does better, but sharepoint can also be ridiculously frusturating, and I'm not aware of any django interfaces into sharepoint yet.

Quick note though: These guys also do a drupal add on for alfresco, and hosed if I can get it to work

I started using django-treebeard in order to get a nestable series of models that i can use for categories/sub categories/sub-sub categories and so on. The problem i ran into is that there is no admin interface for django-treebeard. Before i go and see about implementing one, is there any django-treebeard like solutions that do come with an admin interface that i can just use out of the box?

django-pagecms does exactly this in the admin. I don't know how well it maps to treebeard but it'd be worth digging around in their custom admin pages.

I'm trying to get Django setup on a Fedora Core box. I installed python, postgresql, mod_wsgi, and finally django. I added the following to my httpd.conf:

code:

<VirtualHost *:80>
        WSGIScriptAlias / /home/fletch/projects/domain/apache/django.wsgi
        ServerName domain.com
        ServerAlias *.domain.com
</VirtualHost>

Reloaded the httpd.conf and when I go to domain.com in my browser I get the "Firefox can't find the server at https://www.domain.com." No errors thrown in my apache error_log. Not sure where to go from here...any tips?

edit: I can ping the domain and it resolves to my server

edit2: gently caress I don't know what the deal was but it finally started logging the error in error_log, it was a typo in my django.wsgi file, couldn't find my settings file

Can I still use an htaccess file to password protect my dev environment? How would I do that?

.htaccess files are a lovely crutch (in that they make people ask the question you just did, instead of understanding how Apache config actually works) that get a ton of use because of shared PHP hosting setups.

Since you've got access to the Apache config, just plunk whatever you would've put in a .htaccess file, into a <Location> block, e.g.

code:

<VirtualHost blah>
    blah blah
    blah blah
    <Location "/">
        AuthType Basic
        AuthUserFile /etc/apache2/users.htpasswd
        AuthName "lol no"
        Require valid-user
    </Location>

Yea, that's the trick: a .htaccess is, for the most part, exactly equivalent to placing the contents of the .htaccess within a Location or Directory block whose value is the path to where the .htaccess was. (i.e. /var/www/foo/bar/.htaccess => <Directory /var/www/foo/bar> or <Location /foo/bar>)

Stuff like AuthType and friends don't even work at the top level of a config or vhost; see the docs and note the "Context" header of that doc section. Whenever something I do doesn't seem to work, I first make sure I'm using the directive(s) in the appropriate context

There isn't a hard and fast rule. I've worked on projects that were so small with no chance of growing, that they only contained a few models and views and so I lump them all together into one app for the site.

Then I've worked on projects so large that contained over 50 applications - some of these contained no models, only templatetags for example. Some things just didn't belong *anywhere* such as various utilities that get used across a variety of apps, so they went under their own app called "misc".

Just apply common sense. Groups things together under apps when they logically belong together and you've got enough code going on that warrants the distinction between apps. The beauty of both Python and Django is that your environment is so logically organized from the get-go that in my experience you never really paint yourself into some huge corner that you have to backtrack from when major changes need to occur.

It's perfectly possible to organize your views onto classes if you like, this is actually the plan for the future of generic views (and the admin is already organized this way). http://code.djangoproject.com/ticket/6735

I've been messing around with Django for the past few days but I ran into this error

code:

TypeError at /blog/2009/Jun/30/new/
object_detail() got multiple values for keyword argument 'queryset'

Generic views were cool until I got to object_detail then it spat that error out.
I've been trying everything but can't figure out what I did wrong.

Note: I'm new to this whole programming thing so forgive anything horrendous in the code, I dont know any better.

Separating the generic views from the urls.py seems like i'm kind of double-defining things. I did it because I read that it would be helpful if I was to extend on the generic views. Is this bad practice?

my views.py

code:

from blog.models import Post
from django.views.generic.date_based import archive_index, archive_year, archive_month, archive_day, object_detail

def blog_index(request):
    return archive_index(request, queryset=Post.objects.all(), date_field='pub_date', num_latest=5)

def year_archive(request, year):
    return archive_year(request, year, queryset=Post.objects.all(), date_field='pub_date')

def month_archive(request, year, month):
    return archive_month(request, year, month, queryset=Post.objects.all().order_by('-pub_date'), date_field='pub_date')

def day_archive(request, year, month, day):
    return archive_day(request, year, month, day, queryset=Post.objects.all().order_by('-pub_date'), date_field='pub_date')

def post_detail(request, year, month, day, slug):
    return object_detail(request, year, month, day, slug, queryset=Post.objects.all(), date_field='pub_date')

urls.py

code:

from django.conf.urls.defaults import *

urlpatterns = patterns('mysite.blog.views',
    (r'^$', 'blog_index'),
    (r'^(?P<year>\d{4})/$', 'year_archive'),
    (r'^(?P<year>\d{4})/(?P<month>\w{3})/$', 'month_archive'),
    (r'^(?P<year>\d{4})/(?P<month>\w{3})/(?P<day>\d{2})/$', 'day_archive'),

Also, the reason your particular method is broken is that object_detail is expecting a single item, and your .all() is returning a QuerySet with a more than one item.

That's not the reason for the exception, and I have no idea how you reached that conclusion. The exception is because he's passing too many positional variables to the object_detail view. Specifically slug is passed as a keyword argument and queryset is the 4th positional argument. Thus he's passing the slug as a positional argument in the queryset position, as well as queryset the keyword argument. Also queryset should be a queryset, not a single item.

How is Windows development support for Django, and Python in general? I'm talking about how well the actual interpreter works, as well as support tools like the version control system of choice for the Django community, and especially IDEs and/or editors. This is just for development; deployment would still be on the usual Linux stack.

I was trying to get back into Rails, but my response to asking the same question of them was "good luck; get a Mac." The Ruby interpreter is slow on Windows; the VCS of the Rails community is Git, which barely works on Windows and certainly not as well as SVN or Hg; and the editor of choice for Rails, Text Mate, is OS X only.

I'm getting tired of feeling like a second class citizen. Is Django development viable on windows? Or will I be locked out of some tools and using poor ports of others?

As a corollary, what is the IDE of choice for Django? Or even just the best code editor? (And don't say Vim or Emacs.)

When I was messing around with it, I set up RoR with XAMPP and used Notepad++ all on Windows with no problems. I did use SVN, but I wouldn't say that there was any issue that made RoR development on a Windows box a hardship. You can even use Aptana with the RoR plugin if you want something more than just a text editor to develop in.

That being said, gently caress if I could get Django to ever work on Windows (or Linux for that matter). I didn't spend much time though as it was just a curiosity to play around with.

I had no problems developing on a windows machine with Django back in 0.96, and we used a Debian box for our production server.

I used Notepad++ for editing and tortoise svn as an interface for using svn on windows.

As for the python interpreter, I don't know if it runs any faster or slower, but I don't remember running into anything that stopped me from developing. Just make sure to setup all your path variables correctly in Windows and there shouldn't be any trouble.

This just isn't even remotely true. I've been developing with Django on Windows and deploying on Linux full time for around a year now and I believe in that time I've had a grand total of one issue - some 3rd party Django app that had hard coded slashes in it rather than using os.sep

Install Apache on Windows, MySQL or Postgres - everything just works.

Django development is fine on Windows. I didn't encounter any problems or notice any quirks or anything from doing so during my albeit brief usage of Windows for development. I did get annoyed enough by general Windows stuff to offload my code to a Linux server and edit it remotely, though that's a reflection on my OS preferences rather than any sort of sleight against Python or Django.

As for IDEs, it seems like most developers I know use Eclipse with PyDev, and the rest seem to use Wing or Komodo. Personally, I prefer just using a text editor, specifically TextMate on OS X, gedit on Linux, and Notepad++ on the rare occasions I use Windows.

The issues I've run into on Windows mostly have to do with the binary distributions of third party apps not supporting newer versions of python. This was mostly last year when 2.6 had just come out, so I'm sure it won't be the same situation right now. It's just something you have to keep in mind when developing on Windows.

Here is the MySQLdb which only supports python 2.4 and 2.5 on Windows. I don't know if it will work with 2.6.

Having a problem with Django's admin and ImageField.

I know for a fact that PIL works fine. It'll open and modify any image I try in the shell and regular terminal, so I don't see how PIL could be the problem.

Django's admin, however, won't accept any image, returning the error: "* Upload a valid image. The file you uploaded was either not an image or a corrupted image." for any image I give it.

Any ideas?
