Re: setting up login required pages massly
You can define a custom decorator instead, specifying a custom
login_url:
from django.contrib.auth.decorators import user_passes_test
my_login_decorator = user_passes_test(lambda u: u.is_authenticated(),
login_url='/my/login/url')
Then you can use:
@my_login_decorator

Re: Can't get database driver to use TCP
Ha, i figured out a hack that works. Apparently the low level database connection driver provided by mysql will attempt to use /tmp/ mysql.sock even if you specify 'localhost' or '127.0.0.1' as the hostname. To work around this I added an entry to my /etc/hosts file: 127.0.0.1 localhost database now when I specify the database hostname as 'database' it works! woot. An ugly hack, but if fixed the problem =)) -Dan On Jul 19, 9:18 pm, UnaCoder <[EMAIL PROTECTED]> wrote: > Hi, > > I have django installed on a development box with a local instance of > mysql.

Can't get database driver to use TCP
Hi, I have django installed on a development box with a local instance of mysql. I'm trying to use mysql on a foreign server over an ssh tunnel. I've connected the foreign mysql server to the local port 3307. I've confirmed I can connect to the database using: mysql -u username -p'password' -P 3307 --protocol=TCP however MySQLdb seems intent on connecting to the local database through /tmp/mysql.sock when i specify host='localhost' and port=3307 ... Django has the same behavior. As of right now opening the mysql port on the database server to the public is not an option as it is a production database that is secured by strict firewall rules... This is very frustrating, does anyone know how to accomplish this? Thanks, Dan --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

setting up login required pages massly
hi,
is there a stupidly fast way to make select but many pages to required
login first? I am using 0.96 @login_required is cool, but 0.96 doesn't
support LOGIN_URL in the settings.py yet.
currently i am using something like this
if not request.user.is_authenticated():
return render_to_response('login.htm', {'from':request.path})
for each view's function.
thanks

I've looked at that but, unfortunately, don't come close to understanding what it's doing -- in particular, I don't understand how it fishes the results out of the POST soup that it gets back. I really like the very good widgets that show up in the admin interface. Unfortunately, I took the documentation to heart and only learned newforms -- while the underlying architecture may be better, it seems like several steps backwards in terms of out-of-the-box functionality.

Check out the capabilities of MultiWidget. This provides a mechanism to break apart a single model field into multiple widgets, and get the input from multiple widgets back into a single model field. django.newforms contains a SplitDateTime field and widget for splitting DateTime fields into two form fields (date and time) - modifying this for Y/M/D shouldn't be too taxing.

Always a good idea regardless. Using mod_python 3.3.1 is high recommended. Where problems can come up with hosting multiple Django instances is not with mod_python or Django, but with third party C extension modules which haven't been written correctly so as to be used concurrently from multiple Python sub interpreters. One concrete example which was identified recently was Decimal support in pyscopg module. http://www.initd.org/tracker/psycopg/ticket/192 In short, a C extension module may cache data from one sub interpreter and then use it in the context of a different sub interpreter causing incorrect or errornous behaviour. The problem with Decimal support in pyscopg falls into this category. It is entirely possible that the OP may have been hitting a similar obscure problem in the database adapter being used. The only real way to ensure that such a problem isn't encountered is to use mod_fastcgi or mod_wsgi daemon mode. In both these hosting solutions for Apache the Django instance can be run in a distinct process and thus one doesn't encounter issues with C extension modules that aren't written to work with multiple sub interpreters properly.

Mapping models to CRUD urls?
Loving django still, and now I'm at the point where I'm running into a limit on my understanding on how to map the Model CRUD functions (non- admin style) to a URL pattern. For example: Model1: fielda fieldb Model2: key=Foreignkey(model1) fielda fieldb Model3: key=foriengkey(model2) fielda fieldb So, i'm looking for some help to allow me to CRUD each of these models, and I've come up with a few: http://.../model1/add - calls a view to add a new model1 object to the DB. http://.../model1/edit/#- calls a view to update the model1 ID = # http://.../model2/add/#- calls a view to add a new model2, with a foreign key model1 of # http://.../model2/edit/#- calls a view to edit a model2 of ID #. I guess I continue the same pattern for all sub-models? so model3 would be: http://.../model3/add/#- calls a view to add a new model3, with foreign key model2 of # http://.../model3/edit/#- calls a view to edit a model3 of ID# It seems simple enough, but wanted to get everyones feedback on anything I'm missing, or is it just this simple?

Re: How to loop through a Dict to add values?
well, you're dealing in $$$, so you prob. want floats...but where is
your FloatField? an attribute of your class Price? or can you cast
your Price class to a float?
pr = 0.0
for a in cart:
pr = pr + float(a['choice'].price)
do you understand how classes in object oriented languages work? you
can only add numbers together, not your own custom classes. (without
some extra work i expect - i don't know how operator overloading in
python works, or even if it exists) this is what your error statement
is telling you...that you're trying to add a number to a non-number
class. you have to pull the actual number out of whatever class
structure you've put it in.

Re: schema evolution
yeah, i did a poor/non-existent job advocating inclusion of my SoC work into django-proper. (combination of frustration with my original mentor and busy prepping for starting my phd right after it ended - i just handed it off and didn't follow through afterwards) but i use django quite a bit now and am surprised some sort of this hasn't been merged yet, so i figured i'd bring it up to date and re-release. daev wrote: > It's great!

Re: How to loop through a Dict to add values?
Derek,
Ok...I made the change and I'm now getting the error:
TypeError at /rugs/cart/1/4/
unsupported operand type(s) for +: 'int' and 'Price'
Is 'a['choice'].price' not an Int? It says it is in my model file.
Here is my view
def showcart(request, style_id, choice_id):
s = Style.objects.get(id=style_id)
c = Choice.objects.get(id=choice_id)
#x = c.size, " ", c.price
cart = request.session.get('cart', [])
cart.append({'style': s, 'choice': c})
request.session['cart'] = cart
pr = 0
for a in cart:
pr = pr + a['choice'].price
return render_to_response('show_test.html', {'mychoice': cart, 'p':
pr})
/
Here is my template file:
{% extends "rug_leftnav.html" %}
{% block body %}
{% for a in mychoice %}
{{ a.style.manufacturer }} - {{ a.style.collection }} - {{ a.style }}
- {{ a.choice.size }} - ${{ a.choice.price }}.00
{% endfor %}
{{ p }}
{% endblock %}
//
Here are some of my model classes:
class Size(models.Model):
name = models.CharField(maxlength=100)
def __str__(self,):
return self.name
class Admin:
pass
class Price(models.Model):
name = models.IntegerField()

Re: How to loop through a Dict to add values?
you're not adding two ints, you're adding an int to an instance of your
Choice class. make your line:
pr = pr + a['choice'].value
or whatever you called it.

How to loop through a Dict to add values?
Hello,
I have the following view
def showcart(request, style_id, choice_id):
s = Style.objects.get(id=style_id)
c = Choice.objects.get(id=choice_id)
cart = request.session.get('cart', [])
cart.append({'style': s, 'choice': c})
request.session['cart'] = cart
pr = 0
for a in cart:
pr = pr + a['choice']
return render_to_response('show_test.html', {'mychoice': cart,
'p': pr})
/
Whenever i try this I get the error:
TypeError at /rugs/cart/1/4/
unsupported operand type(s) for +: 'int' and 'Choice'
//
Anybody know how I pull a value out of a dict and add it to a existing
number?
Thanks

Re: Simple Left Join in Django question???
The Django db-api handles JOINs for you. It abstracts them into
"forward", "backward" and "many-to-many" relationships (as documented
on the page I linked before).
Spend some time on the command line playing with these relationships
and you'll see how you can navigate around your models through foreign
keys and such.
Also, if you need quicker answers, join #django on irc.freenode.net
and paste your models at dpaste.com. There's always really bright,
helpful people hanging around on there.

Re: Problem with multiple django versions on mod_python
Thanks for the tip, Niels. I tried that and it didn't work either.
I got to thinking about how likely it would be that mod_python &
interpreters were causing problems. I've used multiple interpreters
for some time and haven't noticed any other strange behaviour. A
little test by printing out the apache.interpreter showed that it
always correctly used the specified interpreter.
I started looking more at unicode. I thought it odd that it always
propagated as a unicode translation error. After a bit of poking
around, I found this line in the trunk version and I wondered if this
might be causing some issues:
django/db/backends/postgresql/base.py: cursor.execute("SET
client_encoding to 'UNICODE'")
Well I can't see why the encoding would be used in both installations,
but I think that postgres interactions were causing the problem,
rather than mod_python. To make a long story short, I switched to 0.91-
bugfix, worked through the conflicts (which is why I hadn't upgraded
earlier), and because it contains a UnicodeDatabaseWrapper, it now
appears to work without problems.
That was a doozy. Thanks all for your help!

Re: Authentication for application with subdomains
Hi David, I'm just starting on an app with the same structure. I think the main problem here is that the username field has to be unique. One possible solution would be to append the domain name to the username before authentication. The user types in 'bob', then the system munges it to 'bob.sub.domain.com' before doing the validation. Anyone know of a less hackish answer? I know we can create custom authentication backends, but I don't see another way to let users have the same username across different subdomains.

I'm glad this came up, I've been struggling with it myself. I'd like
to be able to edit the additional fields that I associated with the
User (via my UserProfile class) from the admin interface, right inline
with the rest of the User fields.
So I took the advice in one of the comments in that thread. I won't
pretend to comprehend it all, but it says:
| class UserProfile(models.Model):
| user = models.ForeignKey(User, edit_inline=models.TABULAR,
num_in_admin=1,min_num_in_admin=1,
max_num_in_admin=1,num_extra_on_change=0)
| # ... my additional fields
This produces an error when validating models,
| Validating models...
| keyapp.userprofile: At least one field in UserProfile should have
core=True, because it's being edited inline by user.User.
| 1 error found.
Okay, so who am I to argue with an error message? I slap a
"core=True," in there with it (on ALL the fields in UserProfile;
anything less causes other problems), and it SEEMS to work! That is,
there's another box in the admin interface for editing a User object,
with my additional fields available to edit.
Too good to be true, right?
Right. :-(
I can neither add a UserProfile nor edit the values of the UserProfile
from the User-edit admin page.
I know, I know, it was unreasonable to expect it to be THAT easy. But
the fact that it DISPLAYS the fields from another table (and
*pretends* to let me edit them even though it discards my changes)
with so little work on my part makes me think it might work if I
wasn't doing something wrong or dumb.
/myproj/mainweb/settings.py:
| INSTALLED_APPS = (
|'django.contrib.auth',
|'django.contrib.contenttypes',
|'django.contrib.sessions',
|'django.contrib.sites',
|'myproj.mainweb.myweb.myapp', # my stuff
|'django.contrib.admin',# user-account administration interface
(provided by Django)
| )
| AUTH_PROFILE_MODULE = 'myapp.UserProfile'
/myproj/mainweb/myweb/myapp/models.py:
| from django.db import models
| from django.contrib.auth.models import User
| class UserProfile(models.Model):
|user = models.ForeignKey(User, edit_inline=models.TABULAR,
num_in_admin=1,min_num_in_admin=1,
max_num_in_admin=1,num_extra_on_change=0, core=True)
|ftv = models.CharField('Favorite TV Station', maxlength=4,
core=True)
|phone = models.CharField('Telephone Number', maxlength=24,
core=True)
| class Admin:
|pass
The UserProfile fields DO show up in the User-editing admin page, as
input fields... but any input or changes to them are ignored/discarded.

Date Widget (or date format) in newforms
Has anyone written a date widget with separate fields for day, month, and year (and, ideally, a calendar) for the newforms package? Failing that, is there any way to change the format in which the text widget used for dates displays and decodes the date. -MM-DD may be better in every way, but it doesn't work for this particular application's users. -- Larry --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: newbie question: generating javascript, avoiding trailing comma
It would probably be easier if you processed crime_list in your view and
generated a 'crimes' variable for use in your template.

Re: newbie question: generating javascript, avoiding trailing comma
There's a forloop.last variable that you could test. Eg:
var crimes = [
{% for crime in crime_list %}
[ {{crime.longitude}},
{{ crime.latitude }},'{{ crime.address }}','{{ crime.type }}','{{ crime.date
}}']
{% if not forloop.last %},{% endif %}
{% endfor %}

Re: Authentication for application with subdomains
It's very simple to implement that application structure. For authentication you must set proper SESSION_COOKIE_DOMAIN variable in settings: http://www.djangoproject.com/documentation/settings/#session-cookie-domain For manage subdomains you can write you own middleware to parse request.META[ 'SERVER_NAME' ] value and setting some needed attributes to request then handle it in your views late. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

newbie question: generating javascript, avoiding trailing comma
DU:
I am a newbie, and I'm working on a simple tutorial for other
newbies. I am trying to generate some javascript, and I have the
following code in my template:
var crimes = [
{% for crime in crime_list %}
[ {{crime.longitude}},
{{ crime.latitude }},'{{ crime.address }}','{{ crime.type }}','{{ crime.date

When this template is rendered to a webpage, I can get something like
the following:
var crimes = [
[-78.817828,42.904851,'17 Rapin

[-78.889458,42.897707,'155 Pennsylvania

[-78.884766,42.915257,'446 West
Ferry','homicide','2006-01-10'],

This is fine, but I think the trailing comma in the final array item
is causing a javascript error in IE. Is there a way to rewrite my
template code to avoid the trailing comma?

Authentication for application with subdomains
I know this topis has been discussed already but I stiil havent find solution. We would like to build up the application that will be used by many customers. After registration the customer will access application via its subdomain name: eg. cust1 = http://cust1.application.com cust2 = http://cust2.application.com etc. This approach requires that authentication should use subdomain name, username and password . How can be this scenario accomplished with django? I think its very common approach when one application is used by many customers and things must work dynamicly ... so using django 'sites' approach is not suitable. Thanks for any advice and hits.

Re: Simple Left Join in Django question???
Thank you for your response
I'm not familiar with the context object - I'll have to do some
research.
I have this working
portfolioPage =
client.objects.filter(project_portfolio__project_display_bit = True)
It's returning the clients data - just not the data for the
project_portfolio (it's not joining)?

Multiple User profiles
Hi there! I just wanted to share opinions on this. I'm in the process of building a rather large site, that's going to expect quite some hits a day. So I want to to keep things as clean as possible. One never knows when I'll be getting my hands dirty again. The User(tm), can have a variable amount of profiles, depending on the sections in the site the user... uses. Just to picture it out: User1: * Base profile * Music profile * Food profile * Chat profile User2: * Base profile * Chat profile User3: * Base profile * Music profile And the list might go on... As you see, every user has a Base profile assigned, and any number of the other profiles. I have the AUTH_PROFILE_MODULE setting pointing to the Base profile, and then I'll load the other profile(s) as needed. I'd like everyone to share his/her insight about this kind of situation. Should I better throw all the data together into the base profile, or keep it separately? Is there a way to define multiple profile settings? signature.asc Description: OpenPGP digital signature
Re: Using Sessions to display the contents of a shopping cart
Lutz,
Yea I don't plan on having the user login to purchase a product from
me. So I guess Session's will work if that is the case. It looks
like I will have to place a cookie on the visitor's computer using
set_test_cookie() and test_cookie_worked() method's so that I'm able
to tell the difference between two users that are adding products to
the cart at the same time. Does anybody know of any problems with
this solution?

I believe in your template you should be able to do something like:
{% for p in project_portfolio_list %}

If you had a view with:

I've tried to search for a solution to this problem for the last 2 hours and I can't seem to figure it out. I basically want to return a joined table from a queryset - formatted for my template. I can't seem to figure out how to do this with the Django database API. With SQL a join query works out to: ''' select project_portfolio.*, client.* from project_portfolio left join client on project_portfolio.id = client.id ''' with the following simplified models: class project_portfolio(models.Model): project_name_char = models.CharField() project_client = models.ForeignKey(client) class client(models.Model): client_name_char = models.CharField The challenge here seems to be that I have to return MULTIPLE project_portfolio objects and THEN get the "client" data - because NOT all "clients" have "project_portfolio(s)" Thank you in advance for any help - Josh --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

I'm definitely seeing this string generated by my descendant of CheckboxSelectMultiple, and I'm pretty sure I saw it when I was using a straight CheckboxSelectMultiple widget as well. It's not immediately clear why user-interface oriented instructions would be stored with the database model -- it seems to me that the user interface code (newforms or widgets) ought to handle this itself. I'm not comfortable subclassing Form, but I do understand using the help_text attribute.

forloop variables without for
Hi!
In a project I get a set of images from a model, and then I display it
on the template. In same template (but in another place), I just want
to display first element of set, and number of objects given. Can I do
it without adding those fields to views.py?
I've found a way for doing first, but it isn't very efficient:
In views:
images = tImage.objects.filter(product=product_id)
In template:
{% for image in images %}
{% if forloop.first %}
{{ image.image }}
{% endif %}
{% endfor %}
Thanks a lot!

Question about comment_utils
Hi all, I'm using Django 0.96 and trying to use James Bennett's comment_utils with my blog application. When I add the CommentModerator subclass and 'moderator.register' statements to models.py, the ManyToManyField class attributes in the moderated class stop working. I keep getting the following error File "/home/web/python-2.4.4/lib/python2.4/site-packages/django/db/ models/query.py" in lookup_inner 938. raise TypeError, "Cannot resolve keyword '%s' into field" % name However, when I comment out the subclass and moderator.register statements, everything works again. Is anyone else seeing the same behavior? Should I be running the latest SVN version of Django to take advantage of comment_utils?

My point was that - assuming the Django community wants to spread the word that Django is the best answer to whatever question - that you have to target people who just want to use an application and demonstrate the greatness. This requires a momentum, a community. If you just not want to bother those people and do not want to be bothered, then, well, let them use Wordpress :) All I tried to say is perhaps that people who are looking for a simple to use blogging solution might want to get there with the least amount of work.

It took me 30 minutes to get my blog engine running, without the design. And, there's no need to "make" for plugins. A Django app *is* a plugin to the django framework itself, if you'd like to see it that way. I have a common repository on the python path with things I tend to use often, like typogrify, markdown, and feedparser. You can just load them from any other app. There would still be the problem of people wanting to "one-click-install" plugins and themes. But why would such a person even think about using a framework instead of wordpress? And I still think that there's absolutely no need to make a de-facto standard blog app in django.

Where I work we migrated away from PHP to Django with great success but it depends on your environment. For us the Django admin was a huge factor since we have teams entering content and the default Django admin was way better than anything we had going so far. There are some performance articles and blog posts, for example: http://wiki.rubyonrails.org/rails/pages/Framework+Performance We benefitted from the Django workflow with its built-in web server. There's also the fact that Django is improving everyday which translates into free new features or things that were hard to do are easy now. For example, databrowse or djangosnippets. And we love Python and also love our jobs more because of the switch. :) Those aren't really resources for you but depending on your in-house requirements it's not hard to find resources online to help guide the decision.

Re: Blog engine
If it is so easy to create a blogging application with Django, then this should be an argument for a standard application, not against it IMHO. At minimum, it could become a nice example application, either as part of the django distribution or as a separate download. And if it is still easy enough, make it a Wordpress killer. Make it as easy to install and to use as Wordpress, being an example for the power of elegance of Django (and Python) - something like Typo or Mephisto for Rails. Another important argument for one de-facto standard are plug-ins and templates. There are zillions of templates (even nice ones) for Wordpress.

Using Sessions to display the contents of a shopping cart
I have the following view:
def showcart(request, style_id, choice_id):
s = Style.objects.get(id=style_id)
c = Choice.objects.get(id=choice_id)
x = request.session ?? # I want to add s and c to my session?
return render_to_response('show_test.html', {'mychoice': x})
//
Everytime the user adds something to their shopping cart then this
view will be accessed. I want the view to store the two parameters (s
and c) into my request.session so that the data in the session can be
showed when the website visitor checks out. However, I'm not sure how
to add these parameters to my session variable. I'm also not sure how
to display all the session data.

4 beginner's questions
Hi, Coming from a Java background, I introduced Django in my company for a new web application. So far, we made great progress and web development suddenly was fun again. Unfortunately, it feels like all time I save because of Django, is spent on searching for an IDE (I still haven't found something really usable), reading the doc and solving trivial Python problems. I hope this will get better once I have more experience with Python. I've a few questions regarding Django I'd like to ask in this and future mails. 1) It is important for me to recreate my environment from scratch (that is, from the VCS). I'd like to have a working application after calling "syncdb". For my own application, I've create an initial_data fixture. But I'd like to recreate users and permissions, too. Is this possible? I looked into django/core/management.py and it seems that "load_data" simple enumerates the installed application so if I want to create a fixture for "auth", the initial_data file must be located inside the django installation. This isn't an option. Furthermore, it seems that "syncdb" always asks for an admin account on the console. Can I somehow suppress that question? Instead, I'd like to load some saved fixture. 2) I'd like to run batch application against our database (periodically using cron). Of course, I'd like to use the same database abstraction as Django uses, so I tried to find a way to initialize the system. What's the recommended way to access models from outside of views? I came up with these lines (conveniently located inside the project folder): #!/usr/bin/env python ... if __name__ == '__main__': from django.core.management import setup_environ import settings PROJECT_DIRECTORY = setup_environ(settings) from demo.models import Demo d = Demo.objects.get(...) ... d.save() 3) I need to create an object with a unique random id - and I would prefer not to use the database specific SQL layer. What's the best way to do it? My naive approach is to declare the id field unique and simply try to insert objects until I get no error. The documentation says [unique] "is enforced at the database level" but it unfortunately does not describe what happens if the constraint is violated. Will this always raise an IntegrityError? 4) I'd like to specify the file name of an uploaded file. Right now, the original filename is kept and I think, this could cause problems if two people upload a file with the same name at the same time. I tried to understand the file upload process in the Django source but there was too much meta magic for my brain. However, it seems that the current documentation doesn't tell the whole story. It seems, that there is a save_FOO_file() in addition to the documentation tree get_FOO_xxx methods... My guess is that manipulators.py is responsible for saving the uploaded file. ... Wait, I think, _save_FIELD_file() will eventually save the file and yes, that while loop is obviously not threadsafe! So I need to set the filename myself.

Re: Random IndexError
This might mean your sourcefile uses '\r' for newlines which isn't
handled correctly by django. If that's the case, this might be worth
filing a ticket, i think.

Re: newforms and models unique=True validation
+1 it works, perfect (I just change the self.cleaned_data into
self.clean_data). Now when you showed me the trick I was able to track
it in docs as well, unfortunately I'm using 0.96 and
http://www.djangoproject.com/documentation/0.96/newforms/ is much
different to http://www.djangoproject.com/documentation/newforms/
Is there anything coming into django that would provide validation of
unique=True out of the box?
Anyway thank you very much

Re: Problem with multiple django versions on mod_python
In case the problem lies in manipulating the python path inside a
section, perhaps you could play another trick to load the
different versions of django. I am doing as follows, though, not with
Location tags but in VirtualHost sections, and it works for me:
Somewhere on the python path, there is a subdirectory,
django_versions. In there, several django trees exist. On the same
level as django_versions subdirectory i have wrapper modules, one for
each django version i need, named django_trunk.py, django_096.py, and
so on. The wrapper code reads:
##
import imp, os
django = imp.load_module(
"django",
*imp.find_module("django", [os.path.join(
os.path.dirname(__file__), "django_versions", "django-
trunk"
)] )
)
del imp, os
all together, the layout is:
/python-path/django_trunk.py
/python-path/django_someversion.py
/python-path/django_vresions/
/python-path/django_versions/django-trunk/django
/python-path/django_vresions/django-someversion/django
Note, there is no need to have an __init__.py inside django_versions,
since the path munging is done in the wrapper module, where the
required django module is loaded from a temporary fixed path set up
dynamically.
To use this, a second wrapper file is needed for the mod_python
handler. This one is named django_trunk_handler.py and should be put
somewhere on your python path as well:
import django_trunk as django
from django.core.handlers.modpython import handler
And analogous to that, you can have django_someversion_handler.py:
import django_someversion as django
from django.core.handlers.modpython import handler
Now, in httpd.conf, this comes together:
...
PythonHandler django_trunk_handler
PythonInterpreter version1
...
PythonHandler django_someversion_handler
PythonInterpreter version2
Finally, you might want to have different manage.py stubs with an
extra first line importing the right django module as django into the
namespace to get going.
Best regards...

I'm getting random IndexErrors. This has risen when loading

Request Context and Generic Views
Hi there! How does it exactly work when I want a RequestContext to be used in a generic view. There's the context_processors key in the dict you gotta pass it, but "A list of template-context processors to apply to the view’s template" doesn't really mean much to me, and even less after giving it a "list" and seeing python complain about callables ;) Might anyone give me an example of a dict I might pass a generic view?

meta path_info, yet again
hello everone, a while back I mailed about a problem with path_info. Basically I'm having the same problem and the previous fix we discussed no longer works. I'm getting this behavior: http://www.com/a/ => path_info = "/a" http://www.com/a/b/ => path_info = "/b" http://www.com/a/b/c/ => path_info = "/b/c/" Apache 2.2.4 mod_python 3.3.1 The previous time I had this error we were able to fix it by removing DocumentRoot from the apache config, but this time that's not really working. This is the virtual-host section with some small obfuscations: ( settings.py is in /opt/splice/pysplice/settings.py ) ServerName xx.splicemusic.com ServerAlias beard AcceptPathInfo On AuthName "x" AuthUserFile /x AuthType Basic require valid-user Order allow,deny Allow from All PythonInputFilter tramline.core::inputfilter TRAMLINE_INPUT PythonOutputFilter tramline.core::outputfilter TRAMLINE_OUTPUT SetInputFilter TRAMLINE_INPUT SetOutputFilter TRAMLINE_OUTPUT PythonOption tramline_path /tmp/tramline/ SetHandler python-program PythonHandler django.core.handlers.modpython SetEnv DJANGO_SETTINGS_MODULE pysplice.settings SetEnv LD_LIBRARY_PATH /usr/local/lib:/usr/local/pgsql/lib PythonDebug On PythonPath "['/opt/splice/'] + sys.path" Satisfy Any Allow from All Satisfy Any Allow from All Satisfy Any Allow from All Alias /media /opt/splice/pysplice/media # for some things we need media served by apache!

Re: context processor question
Hello,
Here it is the part of the documentation you are looking for:
http://www.djangoproject.com/documentation/templates_python/#subclassing-context-requestcontext
This is an extract of the part that you are looking:
If you're using Django's render_to_response() shortcut to populate
a template with the contents of a dictionary, your template will be
passed a Context instance by default (not a RequestContext). To use a
RequestContext in your template rendering, pass an optional third
argument to render_to_response(): a RequestContext instance. Your code
might look like this:
def some_view(request):
# ...
return render_to_response('my_template.html',
my_data_dictionary,
context_instance=RequestContext(request))
I hope that help.
