Re: multiple database support: oracle backend
Sorry Carlos,
those patches are far from complete, and I don't use Oracle myself.
For the moment the backends in the patches use the following to get
the connection:
connection = self.model._default_manager.db.connection
Removing the import and putting in that line should do the trick.
There is plenty more wrong (certainly with that 6110 patch, the 6453
one is a little better), but I haven't had the time to work on it
further.

Re: can't install...
so I installed django from "http://www.instantdjango.com/ chapter1.html" and then did the tutorial, and when I tried to execute it, this is what I got: Page not found (404) Request Method: GET Request URL:http://localhost/crime/arson/ No Crime matches the given query. You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page. do you know what might have went wrong? I crosschecked everything with the tutorial... On Oct 16, 12:29 am, AniNair <[EMAIL PROTECTED]> wrote: > Please check the command prompt window in which you have django > running.

default fields for model (also default model methods and manager)
hi all
I'd like to have certain fields in several models, like alias field in
this:
class Person(models.Model):
name = models.CharField(max_length=255)
alias = models.ForeignKey('self', blank=True, null=True)
class Place(models.Model):
street = models.CharField(max_length=255)
alias = models.ForeignKey('self', blank=True, null=True)
to repeat alias in every model is not DRY. also I'd like to have
Manager returning for example all aliases for all of such models and
model methods to manipulate with aliases. so it should be common for
several models. I see a way to achieve this is to inherit
models.Model, add necessary fields/managers/methods to it and the
inherit my models from it, like:
class MyModel(models.Model):
alias = models.ForeignKey('self', blank=True, null=True)
manager = [my alias manager here]
def getAlias:
[whatever I need]
class Person(MyModel):
name = models.CharField(max_length=255)
class Place(MyModel):
street = models.CharField(max_length=255)
my questions are:
1. is it the right way to go?
2. are there any pitfalls?
thanks
Maxim

Templates
Hi...
I am a beginner using django 0.97 pre with python 2.5.1. I am
trying choose language from the settings.py which has LANGUAGES tuple.
I have
{% for lang in LANGUAGES %}
{{ lang.1 }}
{% endfor %}
Can someone tell me the proper way to do this or suggest a tutorial?
should I return LANGUAGES tuple with render_to_response? Thank you.

Re: How to convert 92.5698 to 92.57
Michael,
Yea I'm already using stringformat in my template. However, in my
view code is where I create the order. When the order is added in the
view and I then look at it in the admin the price is displayed as 74.0
instead of 74.00. Here is part of my view code:
p = float(a['choice']) * int(a['quanity'])
pr = pr + p
pr = round(pr,2)
o = Order()
o.b_name = request.session['orderdetails']['b_firstname'] + " " +
request.session['orderdetails']['b_lastname']
o.b_address = request.session['orderdetails']['b_address']
o.b_city = request.session['orderdetails']['b_city']
o.b_state = request.session['orderdetails']['b_state']
o.b_zip = request.session['orderdetails']['b_zip']
o.amount = pr
o.save()
//
Thanks

Loren,
Yes I got that working However, I'm still having the problem when the
order amount decimal value is .00. So, if the order amount is 74.00.
I only see 74.0 in the admin. My admin field is setup this way:
amount = models.DecimalField("Order Amount", max_digits=6,
decimal_places=2)
Thanks

Re: apache2 + mod_python vhosts conflict

Thanks for all who repsonded...Graham, I'll go through your steps very carefully.

db-6110.patch.

The problem seems to be in django/db/backends/oracle/base.py on line

# each thread may have a different default connection, if so
configured
connection_info = LocalizingProxy('connection_info', _local,
lambda: connections[_default])
connection = LocalizingProxy('connection', _local,
lambda:
connections[_default].connection)
But I don't see how to get the named connection in oracle/base.py.
If that is clear, I would appreciate any suggestions.

One option being considered is to use the multi-db branch at http://code.djangoproject.com/svn/django/branches/multiple-db-support which is already in alpha release.

Re: apache2 + mod_python vhosts conflict
Hmmm, I have been trying to track down what is behind this one for a while. I only do this as someone who knows about mod_python and not as a Django user, so dependent on people trying things and giving feedback. Although someone else suggested PythonInterpreter directive, you are already doing that. A few questions for you as a result. 1. Why are you using: PythonPath "['/usr/lib/python2.5/site-packages/django'] + sys.path" It seems awfully odd that you would be adding django package directory to sys.path explicitly. 2. Are you own Django site instances installed in site-packages directory, or have you gone and put them inside of django package directory for some reason? 3. Do the problems go away if you don't have the ServerAlias directive in each VirtualHost container? 4. Can you add a page to your Django application which dumps out what is in os.environ for each site? I want to see whether there has been any significant environment variable leakage between the two Python sub interpreters which is causing them to interfere with each other. Scrub out any sensitive stuff from environment variables before sending. For what is behind this request, see section 'Application Environment Variables' of: http://code.google.com/p/modwsgi/wiki/ApplicationIssues 5. If all else fails and you simply cant find a way of getting this to work under mod_python, then you might consider using daemon mode of mod_wsgi. That way each will run in distinct processes and no chance of them interfering with each other. Also be interested to see if you hit the problem with embedded mode of mod_wsgi, which is similar to mod_python. This latter check would indicate whether this is a subtle mod_python problem or an issue with cross interpreter pollution in Python itself.

Wiley, I ran into the same problem. Even though I wasn't running two Django installations in the same VirtualHost caching seemed to be crossing my installations together.

Thanks for the feedback! We (well Rajesh and Marcus) have been adding a huge number of tests in a development branch, so you'll be seeing that fairly shortly. I appreciate the request for RESTful verbs in the environment, we'll definitely look into that.

It was just an example (from the link) . Since the original post seems to

Your approach at solving this problem is quite interesting, actually. You seem to have actually managed to find a reason to keep _save_FIELD_file() around. Unfortunately, that's not a very compelling reason for the long term, since it especially has problems when dealing with a model with multiple FileFields (the same _save_FIELD_file() will be used for both fields). In #5361, we'll be moving that processing away from _save_FIELD_file() and into a custom file object, which you've probably already discovered by looking at the patch. Your patch would still continue for a while, since _save_FIELD_file() isn't going away yet, but it may well disappear at some point, so it's better to have a proper solution in place. -Gul --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

To understand your problem you need to understand what
HttpResponseRedirect() is doing. When you return that object, your
server sends the browser a 302 status code. A 302 tells the browser
the desired page can be found under the new (temporary) URL you
specify. The browser then requests the new URL as a GET. It does not
resend any GET or POST data sent to the original URL.
If you want to pass some parameters to that second view, you can put
them on the URL you send in your response-redirect. Something like:
return HttpResponseRedirect("/mysite/secondview/?foo=%(foo)s&bar=%
(bar)s") % request
Or you could store the data in the user session. Or you could just do
your work in the first view. ;-)

Re: image/file uploads, custom filenames, security

I haven't done any testing on that particular situation, so I can't
speak to that one.

There's a ticket[1] in Trac to revamp the way file storage is defined,
which would allow you to override some of how Django selects a
filename. Currently, it won't allow you to use the username, or any
other details of the model the image is attached to, but that's
becoming a common request, so I'll see about adding it before it hits
trunk.

The ticket I mentioned above also makes it much easier to subclass
FileField and ImageField to add or change whatever functionality you
like. I don't know whether PIL already does what you need, but if
you're paranoid, this patch should help you out.

image/file uploads, custom filenames, security
hi all,
i've been playing with ImageField and FileField recently and so
far they work like a charm.
some questions remain, though:
* does django properly sanitize the filename or rather, use
safe temp files? i wonder what would happen if i tried to
upload a file called "../../traverse.txt"?
* how can i enforce a filename on the uploaded file?
i want to completely ignore the remote name of the file
and instead store it as, for example, {{username}}.jpg
* anyone know if the PIL stuff is hardened against image bombs?
(small images that expand to gigabytes when expanded to bitmap)
would it be feasible to subclass ImageFile and replace the PIL
calls with some paranoid homegrown stuff (i.e. ImageMagick),
anyone know a starting point for this?

You can't, at least not in one query.
The nearest would be something like this:
iKeys = [p['iFKeyBuildNr'] for p in
Package.objects.filter(strPackageName__in=['denon_AVR4306']
).values('iFKeyBuildNr')]
builds = Build.objects.filter(iKeyBuildNr__in=iKeys)
There are several variations on that theme, but I'm pretty sure it'll
require 2 queries if you really need the nested in.

Hi,
It is normal that you loose them. This is a HTTP Redirect. The webbrowser
will do a second GET.
You can use from django.utils.http urlencode(request.GET) to build
the new URL.
This will redirect the webbrowser to the new URL with data.
HTH,
Thomas

Re: How to find out if a string is contained within another string
You can set up your regular expression like so: import re number_re = re.compile(r'\d+') And then when you want to pull numbers out of the string, you can use this line: number_list = number_re.findall(input_string) That will give you a list of all the numbers in the string, or an empty list if there are no numbers found. I hope this helps! -Gul --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Request data is lost between two views
Hello,
I loose request data when I call a view with reverse from a previous
view. Here is what I do:
def my_first_view(request):
# Processing here
return HttpResponseRedirect(reverse('my_second_view,
args=(request,)))
def my_second_view(request):
# I would like to processing request data from the previous view,
but request is empty
return render_to_response('results.html', ...)
URLConf:
(r'^mysite/secondview/$', 'mysite.my_second_view', {},
'my_second_view'),
Is request data supposed to follow or is it normal to loose it? Is
there another way to preserve request data between consecutive views?
Thanks!
Divan
