I18N URL patterns and wsgi

[Sebastian Wiesinger]

Hello,

I have a Django project (Django 1.4.5) at an URL like this:

http://host/subdir/django-app

This is implemented with apache + WSGI and is configured in the apache 
configuration:

WSGIScriptAlias /subdir /some/path/to/django-app.wsgi

Now I implemented I18N and tried it on the webserver. It changed the URLs 
to:

http://host//subdir/django-app

Which of course does not work. I expected it to do something like:

http://host/subdir//django-app

Am I doing something wrong? I can't find out how to change that behaviour.

Regards

Sebastian

Well, data modelling is independent of all this - right? :)

I mean, benchmarking should not drive database design; and if it does, then
there is a VERY HIGH probability that you are not doing things right. IF
your models are right, then the problems would be in the way you are
constructing the query and django-debug-toolbar is a life-saver here.

No one will have the patience to look into your code and debug stuff for
you unless you shortlist the possible errors. Well, technically someone
will, provide you pay them :)

Anywayz, if you are unsure what you did, drop the database and recreate it.

Re: Templates: best way to access object attributes described in a external list.

[Bill Freeman]

Are you saying that you need control over which of an item's attributes are
shown and which are not and/or the order in which attributes are shown, or
are you saying that the way python/django converts the attributes to
strings does not meet your requirements, or both?

Your approach can certainly handle both, provided those who will be
maintaining it will have no trouble understanding it.

Rather than  a template filter, I would probably opt for a model method,
producing a list of strings over which the inner "for" could iterate.  Such
a method has access to all aspects of, so it could behave differently
depending on class, allowing for mixed lists, if you prefer.

Re: Is there a way to list users that have logged in within the pass 30 minutes

Thanks for your input, I found this on google also.

def get_all_logged_in_users():
# Query all non-expired sessions
sessions = Session.objects.filter(expire_date__gte=datetime.now())
uid_list = []

# Build a list of user ids from that query
for session in sessions:
data = session.get_decoded()
uid_list.append(data.get('_auth_user_id', None))

# Query all logged in users based on id list
return User.objects.filter(id__in=uid_list)

If your website is massive, the following can cause latency issues(also
hang!).
Check what the SQL that gets generated using the django-debug-toolbar to
get some more cues.

Hi Gabriel

Read about select_related() and start from the appropriate point:

https://docs.djangoproject.com/en/1.4/ref/models/querysets/#select-related

Eg, this will result in only one query:

  qs = OrderProduct.objects.filter(order__user=user).select_related('product')
  for op in qs:
print u'%d x %s' % (op.amount, op.product.name)

Django inline formsets, force initial data to be saved.

[Marc Aymerich]

Hi,
I've spend several hours trying to figure out how to save inlines with
initial data in them.

basically I have a very simple model with 2 fields:

class DirectIface(models.Model):
parent = models.ForeignKey('nodes.Node')
name = models.CharField(max_lenght=64)

And what I'm doing is defining a formset with initial data in it:

class DirectIfaceInlineFormSet(BaseInlineFormSet):
def __init__(self, *args, **kwargs):
kwargs['initial'] = [{ 'name': 'eth1', }, {'name': 'eth2'},]
super(DirectIfaceInlineFormSet, self).__init__(*args, **kwargs)


In this case 2 Direct ifaces with names eth1 and eth2.

The problem is that those ifaces doesn't get stored when I hit the save
button, that's because has_changed == False.
So is there a way to tell Django to save formsets with only initial data ?

Thanks !

Technically speaking, if that is your template, and you end up with

To clarify - you only have one project, with three apps in it. In two
of the apps, which only use generic views, STATIC_URL works correctly,
but in third app it does not.

Do these views in the third app use RequestContext to render the
templates? Generic views do…

Re: Django URLs with/without proxy server

[Bill Freeman]

I don't know then.  If it were me, at this point I'd be single stepping
through the resolver code with pdb (runserver), or if the problem doesn't
happen under runserver, adding logging calls to the url resolver code to
see what it's doing where and when.

Re: urls.py not loading changes

[Bill Freeman]

This should not be a .pyc problem, since upon startup python compares the
modified time of the .pyc to that of the .py, if available.

python will use the .pyc if it can't see the .py .  I don't know what it
will do if the .py is there, but it doesn't have permission to read it
(possible permissions issue).

The other way this could be a .pyc problem is if the .py file was updated
in such a way that the modified time is left older than that of the .pyc
(differences in time setting on the two machines, some funky transfer
mechanism that sets the target modified time to match that of the source,
where the .pyc is newer, or the machine time was messed up the first time
the app was started, yielding a .pyc modified time far in the future).

When I've had troubles like this it has more often been that I've had two
copies of the site on the deployment box, and I've been fixing the wrong
one.

 Hi everyone,

 i have a remote Linux server with a Django application running in a

 Does anyone know what may be the problem?

 Thanks a lot!

Re: Upgrade to django 1.5

[Brad Pitcher]

It should be safe, just test things out. Also, if you have DEBUG=False you
must also include an ALLOWED_HOSTS array, which became required in Django
1.4.4:
https://www.djangoproject.com/weblog/2013/feb/19/security/#s-issue-host-header-poisoning

It should contain a list of domains used to access the site.

Re: urls.py not loading changes

[Venkatraman S]

Well, it so happens that when you ftp the file from your local box to a
remote machine the timezones are mostly different. For eg. i am in India
and we are 'ahead' of the US, so when i push my code to a server in US
timezone, i see this problem most often.

Re: Upgrade to django 1.5

[Joey Espinosa]

Also, if you haven't already, make sure your {% url %} template tags are
properly quoted (unless they're variables). Django 1.5 no longer accepts
named urls that are not quoted; they will be treated as variables if not
quoted (and if they're not actually variables, then you'll get an error
about having an empty string for a named url, which is not allowed).

So this:

{% url myapp_home %}

would become this:

{% url "myapp_home" %}

Just a "gotcha" to point out in case you haven't taken care of it already.

TemporaryFileUploadHandler leaving tempfiles behind on disk

[msoulier]

Hi,

I'm using a ModelForm to upload a large file that ends up being
written to a tempfile on disk. When I call form.save(), the file gets
copied to the final filename, but the tempfile is left behind on disk.

I am using a custom handler, which is a TemporaryFileUploadHandler
subclass, but each method I override calls the parent class' method
first.

Is the tempfile supposed to be left behind?

Thanks

> Hello,
I am not an experienced django developer so maybe this solution doesnt
follow 'the django way', but as i read at:
http://docs.nullpobug.com/django/trunk/django.core.files.uploadhandler-pysrc.html#FileUploadHandler.new_file
TemporaryFileUploadHandler subclass FileUploadHandler. The 'new_file'
method at FileUploadHandler saves
the file name at the class instance as 'file_name' (self.file_name). So, i
would try to overrite the 'file_complete'
method from my own class that subclass TemporaryFileUploadHandler and do
something like:

class MyTemporaryFileUploadHandler(TemporaryFileUploadHandler):

def file_complete(self, file_size):
if os.path.isfile(self.file_name):
os.unlink(self.file_name)
super(TemporaryFileUploadHandler, self).file_complete(file_size)

I'm not sure if self.file_name points to the temporary file, so maybe this
is not util.

Yeah, I'm doing that, but it seems odd to me that the handler leaves the file
around, when it's supposed to be temporary, no?

I use this at the shell sometimes:

from django.contrib.auth.models import User
for user in User.objects.order_by('-last_login')[:25].iterator():
print user.username.ljust(20, ' '), user.get_full_name().ljust(30,
' '), user.last_login

Just alter the queryset to use a timedelta query for last_login
instead of a row limit. Shouldn't be a big load on the system.

Re: urls.py not loading changes

[Bill Freeman]

Yes.  So it is best to select transfer mechanisms that set the modified
time of the .py file to the target machine's current time at the moment
that the newly written copy is closed, rather than caring about the
modified time on the source machine.

Most mechanisms do this by default (cp, mercurial checkout/update, tar).
You usually have to go out of your way to get the modified (and created and
accessed time) reflected from the source to the target.  If doing that,
don't.  If your mechanism preserves modified time by default (maybe rsync?)
see if you can't surpress it.  Or "touch" the file after transfer.

How to pass a value from a Django View to a JQuery Slider bar.

[7equivalents]

Hello, my goal is to use a Django powered website to control the brightness 
of a light. I am using a JQuery slider bar as a dimmer switch. When the 
JQuery slider bar loads, I need it to iniciate to a value I have in my 
database.

I already have my View, Model, and Template setup, and can pass variables 
from the View to the HTML part of the template. My Question is, How do I 
pass the variable from the View to the JQuery slider bar?

Thankyou for any help. I am new to Django, JQuery and pretty much all Web 
programming, my main experince is working with microcontollers and low 
level language between chips.

[Shawn Milochik]

Probably consume the view with AJAX, doing a POST on the change event
of the slider.

http://api.jquery.com/category/ajax/

Put your result in a dictionary within your view and return it as JSON:

return HttpResponse(json.dumps(result), mimetype="application/json")

Re: How to pass a value from a Django View to a JQuery Slider bar.

[Gabriel]

If I understood it right, I think it would be enough to serve the
javascript with the initialization
value hardcoded in it, right? Like using {{ }} tags.
Is there a way to do this if there's a separate .js file?

So are you saying the best I can do is show users that logged in xx minutes 
ago, even through they may have logged off?

Actually, yes. Because most users never log out. They just close their
browsers. So even if you did look at the session data it wouldn't
represent reality.

You could get fancy and log the timestamp of the last request of every
user with middleware and compare it to your session timeout. Of course
that still wouldn't know when people closed their browsers when before
their sessions expired, but it should capture users active beyond the
session timeout.

Yes, Thankyou for helping me clean up my line of questioning, That is 
exactly what I want to know, can I use the {{ }} tags to do this, and can 
they be placed in a seperate .js file.

Would this do the trick?

I am still kinda new to django, about a month now. :)

No, because that will just invalidate the cookie so that they'll have to
log in again when they reopen their browser.

It doesn't magically notify your Django app that the browser closed.

This has nothing to do with Django. It's an HTML or maybe a JavaScript
thing. Just do a Google search.

Unless you're going to dynamically generate the WAV file and need help
streaming it, I don't think list this is the best resource.

No, you can't execute arbitrary Python code on the user's machine.
People were playing wav files (hampster dance, anyone?) many years ago
in HTML.

Right. The Python code runs on your webserver, not the user's computer.
So... you could probably play a sound your webserver, but that's not
likely to do you much good ;)

Re: Impossible? Django with NTLM SSO auth on windows?

[Avraham Serour]

Hi,

Does anyone think using ntlm instead of/on top of oauth/social logins.
Ideally this could be given as another choice of login/authentication on
top of oauth options, this would be a solution to the user not having to
remember yet another password. does linux have anything like that?

would this be practical, has anyone thought of this?

Re: How to pass a value from a Django View to a JQuery Slider bar.

[Michael Pimmer]

I usually keep a separate .js file in my templates where I set such 
javascript variables (preferrably as a hash or module). You can directly 
include it in the base.html template so you don't make 2 requests out of it.
The main javascript functionality should definitely go to the static 
files though.

Re: Impossible? Django with NTLM SSO auth on windows?

[Andre Terra]

FYI, I found a nginx module for Kerberos authentication too:
https://github.com/fintler/nginx-mod-auth-kerb
http://michaelshadle.com/2010/01/17/spnego-for-nginx-a-start-at-least

It hasn't been updated in quite some time, but it is apparenlty working and
perhaps one of you will feel like taking a swing at it.

django DB optimization

[Subodh Nijsure]

Hi,

I have implemented a django application that willl maintain schedule
for 100s of people that work for a company. People access this
schedule using desktop or mobile device to lookup their task list for
current day, this week etc.

Now the question is how do I scale this -- example when user joe looks
up his schedule for today essentially I end up doing a query get
records for today, where user name is joe. Same thing would happen
when Mary looks up her schedule, we do DB lookup for records for Mary.

I am worried that when 10,000 people start to query this my database
is going to become a bottleneck (?) Should I be implementing some of
home grown daemon that caches the data associated with most common
queries and serve the data out of that daemon.

I am sure I am not the first one to encounter this issue, how do
people scale their query response time when using django as their
framework.

(Hope this Q made sense...)

Re: django DB optimization

[Shawn Milochik]

Rule #1: Measure first.

Don't add any complexity to fix any bottlenecks until you know for a
fact where they are. Once you know where one is, the solution will
probably be fairly obvious. Caching, denormalization, etc.

Come up with a way to stress-test your app and add measurements.

Well, data modelling is independent of all this - right? :)

I mean, benchmarking should not drive database design; and if it does,
then there is a VERY HIGH probability that you are not doing things
right. IF your models are right, then the problems would be in the way
you are constructing the query and django-debug-toolbar is a life-saver

Hi Ugorji,

first off, to enjoy programming, do not let anything look so big a
problem to tackle. Of course, there would be challenges, but none of
these challenges should be bigger than they really are.

That said, while starting out, you must have successfully created a
project called mysite. This happened when you ran the following
command:

django-admin.py  startproject mysite

This would've created a project file called 'mysite' at a location you
chose by yourself; this location is where you ran the above command
from. E.g on a windows machine, if you issued the command from
'c:/users/ugorna/desktop>>'
The project folder would've been created on your desktop!
Go to that project folder called mysite, open it and you would see
some .py files in there; one of these files is settings.py. Edit it
with your choice editor.

Hope that helps.

Just to clear my doubt, have you read about python at all??? If yes,
cool. If no, you may want to take a look at it first before coming to
django.
This would make your django experience worthwhile.

Regards.

Re: New to Django & Programming - Trying to work with the tutorial. How to edit mysite/settings.py

[Gabriel]

In case you have no previous experience with Python, I would seriously
recommend
you follow Zed Shaw's Learn Python the Hard Way (
http://learnpythonthehardway.org/)

Don't let the title scare you off, it's actually a great book for
programming beginners. It's
free online, or if you're willing to pay there's a $30 version that comes
with video lessons.
It'll cover anything from setting python up, to working with the terminal,
to picking and
configuring your text editor.


In case you're just looking for some direct tip, and use GNU/Linux, I'd
suggest typing
gedit mysite/settings.py

Gedit is a good enough editor to start with, it has some helpful programming
features out of the box that will not get in your way, like syntax
highlighting.
If you're using Windows, I'd recommend getting Notepad++. I haven't used it
in a long
time, but it used to be like gedit.

I can't help with Mac stuff, though...

Django Simple Captcha - Manually displaying the Captcha field in a template

[mmuk2]

Hi,

I'm currently trying to implement django simple captcha on my form. It's 
quite straight forward to set up with the "out of the box" django form 
functionality - just add a captcha field to the form in forms.py, and in 
the template, use the built in django form template like this:

{% form.as_ul %}

And this dynamically generates the HTML for all my form fields including 
the captcha field:

Captcha:




My issue is that I can't use {% form.as_ul %} to display my form, because 
each field requires customised css styling.

So I'll need to replace the {% form.as_ul %} with the actual HTML code in 
my template.

This works fine, however, the captcha field value needs to be re-generated 
each time, so I need to generate the captcha field value dynamically each 
time the form is loaded.

What is the best way to do this? I guess I'm looking for something similar 
to the way the csrf token works, ie. the {% csrf_token %} tag, which 
dynamically generates the csrf token. Is there an equivalient for simple 
captcha, like {% captcha_value %} or something?

thanks in advance,
Mark

Sure - just provide the initial data as actual data. If, instead of using
'initial', you pass the same content as 'data', the form will be saveable.

Re: New to Django & Programming - Trying to work with the tutorial. How to edit mysite/settings.py

[Nikolas Stevenson-Molnar]

You need a text editor. Source code is plain text, so something like
Notepad will work. But in practice, you'll want a source code editor.
There are many out there, some free some paid. My personal favorites are
Notepad++ (http://notepad-plus-plus.org/) on Windows and TextWrangler
(http://www.barebones.com/products/textwrangler/) on Windows. Though I
haven't used it myself, Sublime Text (http://www.sublimetext.com/) looks
really cool.

You could also use an IDE (which is an editor plus other project
management tools). I prefer PyCharm (http://www.jetbrains.com/pycharm/)
for this. Or on the free side, try Aptana (http://www.aptana.com/)

Happy coding!

The error message says you have an indentation error. That means you 
need to make sure to have exactly the same quantity of indentation each 
time the source code gets indented.


In practice, most people use four spaces and never use tabs.

Most text editors let you configure them to use spaces instead of tabs.

If you do that you will need to replace all tabs with your preferred 
number of spaces.


Once you fix that the error will go away.

Re: Django 1.4.3 contact_form

[william ratcliff]

Check the indentation of the clause I mark with *
Also, do you use tabs?

def contact(request):
   if request.method == 'POST':
form = ContactForm(request.POST)
if form.is_valid():  
 asunto = form.cleaned_data['asunto']
 recado = form.cleaned_data['recado']
 email = form.cleaned_data['email']
 ccopia = form.cleaned_data['ccopia']
 from django.core.mail import send_mail
 send_mail(subject, mensaje, email, 'x...@xx.com')
 return HttpResponseRedirect('/gracias/')
else:
form = ContactForm(
initial={'subject': 'Me agrada su sitio!'}
)
return render(request, 'contacto_form.html', {
 'form': form,
})
