redirect after login
Hi,
I have the below line in my login code which decides the redirect
screen on successful login
redirect_to = request.REQUEST.get('next')
However redirect_to is always evaluating to None even though the
parameter 'next' is part of the url. Any idea what i might be doing
wrong?
Thanks in advance.

Django CSRF 1.2
I have a PERL test script for DJANGO connection test. It works on
Django 1.1 admin login page, but doesn't work on 1.2. The request
contains:
Forbidden (403)
CSRF verification failed. Request aborted.
Here is the perl script:
$response = $ua->get("$url/admin/");
my @lines = grep /id='csrfmiddlewaretoken'/,$response->content;
$lines[0] =~ /id='csrfmiddlewaretoken' name='csrfmiddlewaretoken'
value='([a-f0-9]+)'/;
$csrfid=$1;
my $req = HTTP::Request->new(POST => "$url/admin/",
[csrfmiddlewaretoken=>$csrfid]);
$req->header('Referer', "$url/admin/");
$ua->cookie_jar->add_cookie_header($req);
$response = $ua->request($req);
What's wrong? Have I forgot something?
1. Read the csrf hidden input
2. Keep cookies
3. Set csrf input to POST
4. Set cookie to headers
5. Set refer page (beacuse of HTTPS conection)
6. Make a POST request
Where can I find similar python script to test login page?

Query about GenericTabularInline
Hi I have set up a Generic inline (using generic.GenericTabularInline). It behaves differently (and from my application's point of view, wrongly) from the standard admin.TabularInline in two ways: 1. It doesn't have the plus icon next to foreign key fields that allows users to add new foreign objects directly from this view. 2. In settings.py I set TEMPLATE_STRING_IF_INVALID = 'PROGRAMMING ERROR! INVALID TEMPLATE STRING.' Unfortunately, this string then appears on the left of each entry in my GenericTabularInline. Have other people experienced this? If so, should I log this as a bug or am I doing something wrong or making a wrong assumption about how it should work? Thanks.

Re: Authentication
Eeek, that looks pretty hacky, I wouldn't do that.
I can think of a couple of options:
Write some middleware that runs before the authentication middleware,
and updates REMOTE_USER.
or
On your dev site only, specify that the RemoteUserMiddleware use a
header rather than the REMOTE_USER environment variable (see the docs
you were originally looking at), and use a browser extension to inject
that header into your requests.
Cheers

Re: redirect after login
Did you get the next parameter in the login template and append it to
form action, If that is not done then once the form is submitted the
next param would be lost.

Suppressing validation
Hi all,
How would I suppress validation on a django.forms control instance? Eg, I
have:
link = forms.CharField(widget=forms.TextInput(attrs={'size':'70'}))
or
link = forms.URLField()
How would I stop Django from enforcing that the field must be populated with
data? I think that this is what's causing my form not to save.

I can't understand what you are trying to do. You have a view called
current_datetime, which then queries a WML service that seems to look
up words in a dictionary (ie nothing to do with dates or times), and
you then say you want to 'restify my view'..
What precisely is it that you want to 'restify' about this view? Do
you want POST requests to the service URL to create new entries in
this dictionary, DELETE requests to remove words? Typically REST
examples only show interaction with models, because REST is usually
used to provide state-less web services for accessing collections of
objects. You aren't doing any of that..

The URL doesn't match one in your urlconf, but would with an appended slash, which is missing from the URL (the '/' in your URL is part of the query string). Since this is a POST request, it cannot redirect without losing data, so it is a runtime error.

Re: Django in production on Windows
I'm not the windows guru I used to be. Converted my household to Ubuntu Linux and have been pretty happy since. The kids miss some flash games, I don't miss the virus issue. www.cygwin.com is one possible windows avenue that might work. When I was hanging on to windows because I had to support it, I used cygwin religiously. I found a lot about cygwin to be frustrating, but it was better than being w/out unix/linux all-together. Unless you absolutely positively must remain a Windows/Microsoft supporter, I recommend grabbing an old decommissioned box and slap Linux on it. It's gotten a lot easier with the latest distributions. I use Ubuntu for most, but Cent-os might be just what you need, and I've heard good things about Mint, but haven't gone there. If you can live without the Xwindows/GUI almost *any* machine will work and perform just fine. W/Google and apt-get command line, you should be able to get a box up and running inside of a couple of hours. I can imagine Linux is frightening, but it doesn't need to be. For me it's like a big box of toys, you might have to do a fair amount of reading, but there's a lot of good documentation and Google can be your friend. I prefer googling linux issues over Microsoft Technet issues. Tech-net can be such a royal PITA. Ctrl-R for reverse command line search was a godsend to me, why Microsoft has never implemented something, so useful, is beyond me. F5-F6, I forget which key brings up the annoying scroll box for command history... What were they thinking?

returning type and value
Hi all,
I have this in my model.py
def recipe_cost(self):
total = IngredientInfo.objects.filter(recipe =
self.id).aggregate(Sum('total')).values()
return total
Then in my admin.py I call that to display the cost.
class RecipeAdmin(admin.ModelAdmin):
list_display = ('title','recipe_cost')
I can see the cost but it's being returned like this:
[Decimal('500.00')]
But obviously I'd just want the value 500. What should I change?
Thanks

What you are calling total isn't the total, its a ValuesQuerySet. You
want to extract the value from there, and convert it into whatever
format you want.
Eg:
def recipe_cost(self):
qs = IngredientInfo.objects.filter(
recipe=self.id).aggregate(Sum('total')).values()
return unicode(qs[0])

Alphabetic filtering of Django Admin drop down menu
Hi All In one of tables that we access through the Admin menu we have around 50,000 objects which return string o/p as the return value, but the problem is that it takes too long for them to load ( more than few minutes) in a drop down I have also gone through the raw_id_fields but it doesn't fit our requirement Is there a way that we can have alphabetic pagination in the drop down menu of Admin Thanks in advance Subramanyam -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Alphabetic filtering of Django Admin drop down menu
If you can't use raw_id_fields i guess you should write that view and use javascript to search inside the view. Can you use a auto complete approach instead a drop down menu?

Re: django auth for existing cgi
Copying things from request.META to the env parameter of Popen allows me to get the cgi off the ground.

Is this a good practice, or is it just plain stupid?
Hi everyone,
I hope that this group is the good one for this kind of questions.
So today, I decided to write a tiny django app (in less than 5 minutes
actually) that
helps me add views arguments to templates contexts automatically.
For eg.
def latest_tagged_objects(request, obj, limit, tag): """ Displays
the 'limit' latest objects 'obj' tagged with 'tag' """ # Retrieve these
objects #create a context that will include the args passed to this
view along with #other variables context = dict( obj=obj, limit=limit,
tag=tag, #Other variables here )
I do this often. i.e. add views arguments to my context, so I wanted to
write a
middleware and a context processor that will do it for me.
I wrote this: https://github.com/initpy/django-viewctx
With this app I can omit 'obj', 'limit', and 'tag' in the previous
dict and have them available in my template as: {{view.kwargs.obj}},
{{view.kwargs.limit}}
and {{view.kwargs.tag}}
It was so simple that I'm still wondering if it is a good practice or
just stupid.
Thanks for your help and suggestions!

This is what happen when I submit a form with a galeria and two fotografias. the methods are called in this order: 1. Galeria.clean - don't know the fotografias yet! 2.

Fotografia.save - second foto So it seems if someone wants to execute some code after all the form has been processed, he has to do that somewhere else. [ Maybe in the form submit view? ] Anyway if I want to perform a validation there, it is to late. Maybe the only solution would be to do that in the GaleriaAdmin.save_model, and have to see the request parameters to know how many new files have been uploaded... signature.asc Description: OpenPGP digital signature

handling generated files

One of the approaches would be to store the features in a table - the features can be associated with functions or in the function(as mentioned in the same ruby code there, in this case-the view) check the value of this feature and have the flow based on this.

Re: Django in production on Windows
Eeek. Just had a poke around with getting Django running on IIS. Making it work with FastCGI will need a bit of work; doesn't work out of the box and isn't well documented as most of the focus has been on PHP. It does seem to work ok with PyISAPIe. I'd probably install Apache and use that instead though, either replacing IIS, or using IIS as a reverse proxy to Apache.
