I do remember reading a blog (someone may be able to find the URL) where the author mentioned the same problem. He managed to find out that it was caused by changes queryset-refactor, especially the way QuerySets behaved during pickling.

Re: Pickling Querysets (Query?)
Hi, this is how I do it, but don't rely on effectiveness of this
solution - I'd be the first one to say that I'm a mediocre programmer
:)
def serialize(data):
'''Input: instance of PluginParameters
Output: base64-encoded string that can be stored in a database
'''
if not isinstance(data, PluginParameters):
error('Attempt to serialize data of unsupported type (%s)' % type(data))
raise TypeError('Cannot serialize data of type %s' % type(data))
# Loop through all attributes, identify any QuerySets
# and use only their 'query' attribute for pickling (disregard the rest)
for attr_name in data.__dict__:
value = getattr(data, attr_name)
if isinstance(value, QuerySet):
setattr(data, attr_name, value.query)
if _compress:
res = b64encode(zlib.compress(pickle.dumps(data)))
else:
res = b64encode(pickle.dumps(data))
debug2('Serialized parameters: %g bytes' % len(res))
return res
def deserialize(data):
'''process base64 encoded pickled object
and return an instance of PluginParameters
'''
debug2('Deserializing parameters: %g bytes' % len(data))
if _compress:
res = pickle.loads(zlib.decompress(b64decode(data)))
else:
res = pickle.loads(b64decode(data))
# identify any 'query' object and reconstruct the original QuerySet
for attr_name in res.__dict__:
value = getattr(res, attr_name)
if isinstance(value, Query):
# the black magic starts here ;-)
model = value.model # get the original model owning the query
qs = model.objects.all() # create a QuerySet based on that model
qs.query = value # reattach the orignal 'query' to the QuerySet
setattr(res, attr_name, qs) # and inject this back to the
# PluginParameters object
return res

Re: Python Multiprocessing With Django
> I have a management command that that starts up a few process to process a > request: http://dpaste.com/7925/. Hi, I was recently debugging similar issue and came to a conclusion (which may be wrong of course :) that multiprocessing and Django DB connections don't play well together. I ended up closing Django DB connection first thing in the new process. It'll recreate a new connection when it needs one, but that one will have no references to the connection used by the parent. So, my Process.start() calls a function which starts with: >>> from django.db import connection >>> connection.close() This solved my problem.

Personally, I don't think it is a bug, as we both pushed Django well beyond its "area of expertise". I really believe that Django is great for serving web content and everyone (including) me trying to implement it in different areas must be ready for problems and gotchas here and there. But YMMV.

Re: ORM using tons of memory and CPU
Hi,
correct me if I got it wrong, but you essentially need these 4 things:
1) obtain the date for the the newest messages to delete
2) get cacheID of all objects to be deleted
3) delete the files
4) delete these objects from the database
So, you could use something like this:
# get the date
newest_to_delete = datetime.today() - timedelta(days=settings.DAYSTOKEEP)
# get cacheID's of emails to be deleted, requires Django 1.0+
to_be_purged =
archivedEmail.objects.filter(received__lte=newest_to_delete).values('cacheID',
flat=True)
# to_be_purged is now a Python list of cacheID's
for item in to_be_purged:
delete_file(item) # do the os.unlink() operations
# now delete the entries from the database
archivedEmail.objects.filter(received__lte=newest_to_delete).delete()
Since you keep all files in flat directories, I'm assuming that you
are not deleting millions of emails per day (otherwise the file lookup
operations would really be the bottleneck). Hence, this "list of
cacheID's" approach might be the fastest way. The iterator idea
suggested before is good too, you'd have to compare them yourself on
your data set to figure out what works better.
Hope this helps

Hi, I'm not sure why you'd think the structure is wrong (i.e. state actual errors or problems rather than generic statements). However there is one problem with your Choice model. It does not have any self.question, so __unicode__() can't really return it. You probaby want to use "return self.choice" there (or compose some text string based on existing model fields).

Re: Models Tutorial Django
Hmm, I can't see anything wrong with your code, so I'm gonna go to the basics - how about your code indentation? Is the "def __unicode__()" the same way as your model field definitions?

Re: Shows indendation error
Ravi, the "default" lines where you just uncommented existing lines (like the "include admin") start with spaces, the lines you've created start with Tab characters. Mixing tabs and spaces is not a good practice (generally, it's recommended to use spaces only). If you swich your editor to "display special characters" or similar (most editors can do that), you'll be able to see it yourself.

Hi, is the statistics user-dependent? If not, just create a cron job (or similar, depending on your platform) that will calculate the statistics every hour and maybe even create the main blocks of the page to be displayed. You can either create a custom management command to do this or write a script that uses ORM (and templating system) and Django cache. It very much depends on you setup, but should not be too difficult. Basically, you probably don't need a "view" to populate the cache.

Re: generate cache by visiting protected links
> ret_val = stats_top_callers_per_year(_request)
> cache.set(reverse("stats_top_callers_per_year"), ret_val)
Hi,
it's your code and I won't try talk you out of it :)
However, I don't see any reason why you couldn't call
"stats_top_caller_per_year" from an external script, unless you do
some magic related to request in that function. You're overriding the
user to be the one with pk=1 anyway, so you can do the same in a
script launched by cron the same way.
As long as you have a system-wide cache (ideally memcached backend),
nothing prevents you from doing that.
As for the cache key, it can be anything you want as long as it's
unique, less than the backend allows (I think it's 250 chars for
memcached, see the docs) and does not contain whitespaces (some cache
backends do allow those). A common idiom is an md5 of something that
uniquely identifies the cache object, but in your case you'd be free
to call it "stats_top_callers_per_year" or similar. No need to play
with reverse().
It's all just Python and Django does not really get much in a way
unless needed. So, no one tells you what the cache keys must look
like, and it's unlikely that you'd stumble upon cache keys Django uses
internally.
HTH

I personally don't like spawning another thread in a request-response cycle, but if it works for you, be happy with it :) Based on the print statement on your code I assume your website does run under the development server, so you may have very different requirements than a usual production (read: always running) site :) > As for the cache key, i did the reverse because i thought i had > read in the documentation that this was the standard way Django puts > stuff in the cache. Sure - you can do it, no problem. The reason Django uses it is that it caches various pages and the url pattern is a good way to make sure that the cache key is unique for each page. You could put anything there, even a static string :) > But it's not the link as returned by reverse, though i haven't found yet > what it is. If i find it, i can set i correctly in the thread so that I don't > have to manually check to see if the page is cached when a statistics page > is called. You will always have to check it, as it's not guarranteed to stay in the cache forever. Assuming that the data is in cache is a Bad Thing :) If you set your cache key to "yearly_statistics" or something similar, you will have no issue with figuring out what the key is :) Cheers Jirka -- You received this message because you are subscribed to the Google Groups "Django users" group.

Is it the data calculation, or actualy constructing the HTML page from the data (read:context) and page template? If it's the former, I'd still cache inside the function that calculates the data (with a fixed string key) to get the "transparency of the program". Using the "hack" with the cache key you plan to use sounds clever, but a bit difficult to pick up if someone else needs to read and understand the code later.

Re: generate cache by visiting protected links
> I still have 2 approaches i can take. I still believe that there is a 3rd option there - to bypass the view / auth / login machinery completely :) If your primary goal is to cache the statistics and the statistics does not depend on the user that is logged in (you did pass a user with pk=1 in one of your previous emails), then you don't really need to call any view to cache the data. You can call the function that calculates the statistics (that would cache the data internally within the function), then call this function from anywhere upon start of your webserver (or cron job, as mentioned before). As long as you have a global cache (i.e. memcached), this would work very nicely and you would not have to do any urllib2 login magic. Let me give you a short example: def stats_top_callers_per_year(some_parameters_not_tied_to_a_specific_user): cache_key = 'stats_top_callers_per_year' data = cache.get(cache_key) if data: return data # calculate the data somehow cache.set(cache_key, data) # <- set appropriate timeout there Then have small script called before (or shortly after) your web server start, that would import this function from your code, hence calculating the statistics. Then, as long as you use memcached, your web would use the cached statistics every time the stats_top_callers_per_year() would be called frmo your views.

Upon downloading, just unpack it somewhere on your system where all users can read the files and set LD_LIBRARY_PATH environment variable to point to that dir. So, I have the following line in my /etc/profile: export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/oracle/instantclient_11_2 This should do the job for you.

Hi there, while I don't have first-hand experience, I do remember (from EuDjangoCon) that this can be achieved quite effectively using perlbal's reproxy feature.

Anything beyond a question mark is a parameter and is better handled inside your view. So, your urls.py would look like this: (r"^wap/di/sub", hellow) And your view would contain the following code: def hellow(request): word = request.GET['word'] return HttpResponse(word) But you should need two things: - the code does not contain any error checking (i.e. what happens if "word" is not provided in the URL - There is a security issue.

Re: Import csv file in admin
I must still be missing something here. If all you want to do is to
read CSV file and save the data in the database, I still don't
understand why you use the forms machinery.
You only *need* to use the data model, e.g.
from myapp.models import Data
csvfile = csv.reader('something.csv')
for line in csvfile:
do_necessary_data_conversions_or_checks(line)
try:
Data.objects.create(field1=line[0], field2=line[1], ...)
except (IndexError, IntegrityError):
print 'Invalid line encountered:\n%s' % line
What am I missing?

Re: Start project not working
Hi, first of all, if you will be sending emails like these, you're likely to get ignored by people who are otherwise happy to anser questions like yours (hint: 3 consecutive emails about the same topic in 2 conferences, "anonymous" user etc.) Now for the real "answer". You have not told us anything to identify the issue. Your django-admin.py is clearly working as it responded with a standard error message (no need to copy in full to the email). This message appears if parameters supplied to django-admin.py were incorrect. Since you have not actually shown what exactly you've typed, no one will be able to tell you what is wrong. I'm going to guess that you have not typed "django admin-py startproject myproject". This would not give you the "usage" message.

All the code you are writing for Django is run on the server and only web pages are *displayed* to users on their machines. This means that in order to import a CSV file, you need to transfer it to the server first and then you'll be able to import it there. Note that this has nothing to do with the admin site. This is a fundamental think to understand. I'd suggest that you forget the admin site for the moment and focus on the "transfer CSV file to server first". Take a look at the email Felix has sent you regarding FileField and try to code the part that handles file upload to the server. Once you have that, you can start thinking about importing the contents of the file into the database. Cheers Jirka P.S. OK, there is a way to import data without uploading them to server first, but it's much more complicated than the one outlined above and involves multiple different technologies that have to work together. -- You received this message because you are subscribed to the Google Groups "Django users" group.

Christian,
any solution similar to jCryption would not add much security to
your forms. Since it does not use challenge-response, anyone who could
obtain the plain-text form data can now obtain encrypted data and the
encryption keys (and the fact that you'd be using something like
jCryption). So, not much security added, only a bit of obfuscation.
So, you should use SSL if you worry about security. Sorry.

Hi Bill, this is technically impossible, two programs cannot listen on the same TCP port (on one interface). It's very likely that it was Django webserver listening there.

Well, using a web server to start VNC still seems like a bad idea. How do you stop the VNC server once a user does not need it anymore? The SSH approach is a good one (for extra security, you may require users to tunnel the VNC traffic via SSH). Or you can just leave the VNC server running all the time, is there a problem with that? I just don't see why you would need to start the VNC server dynamically, but that's well beyond Django and OT for this conference :) Cheers Jirka -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: spaces preserved
> Can someone please suggest how to get the complete string ?
Passing (semi-) arbitrary strings in GET parameters can lead to all
sorts of issues (probably less for english-only sites). You might be
better off by passing primary key of the item model or some other
unique identifier that is "web safe" (number or simple string with no
whitespace).
So, in your form you'd have:
{{ machine.product_name }}
and in your view:
form myapp.models import Machine # or whatever it is
pk = request.GET['product']
value = Machine.objects.get(pk=pk) # or use get_object_or_404 shortcut
Hope someone can describe it better than me as I'm not a web developer :)
Cheers
Jirka
P.S. This all assumes you pull the form entries from your database.

Re: How crypt python code
Hi, You can't really. The code has to be executed, therefore it has to be readable by the server. So, by definition, it is readable by sever admin(s).. You could implement some obfuscation, but it,s not really worth it. The best you can do is to check your hosting contract/agreement, see what it says about ownership and privacy. Or use your own server(s) in a trusted environment.

It depends a bit on the context (i.e. do you really want all objects
or just the most recent ones?). I'll only provide a few hints.
- convert whatever you need to combine into lists. You may want all
or just latest 20 objects, i.e
>>> movies = Movie.objects.all()
>>> books = Book.objects.all()
or
>>> movies = Movie.objects.all().order_by('-id')[:20]
>>> books = Book.objects.all().order_by('-id')[:20]
then
>>> my_objects = list(movies).extend(list(books))
then
>>> my_objects.sort(key=...) # see http://wiki.python.org/moin/HowTo/Sorting
Hope this helps

Re: form.has_changed always true?
Hi, if I digress from the has_changed() problem, you mentioned you wanted to send email after a user profile has changed. Assuming that the profile is a model in the database, you might consider tying your logic to the model rather than the form. The post_save signal tied to the profile-related model might just do the trick for you.

Re: Serving https with runserver
>> Then maybe web server is the best option. In all cases you have to >> configure something until someday 'runserver' come with ssl support. I think that no one would really object if runserver was SSL-aware, however people requesting it need to be aware that having an SSL-aware webserver is significantly more difficult that having a simple HTTP web server. The things that come to mind are: - extra dependencies: I'm not sure about all of those, but at least openssl comes to mind - the need to have a server certificate: While not a terribly complex task to generate one, some decisions need to be made (e.g. where it will be stored?). - more complex URL handling for testing. As local server uses port 8000 by default and links are usually relative, it's not a big deal. But if people start relying on having HTTPS dev webserver, they might get confused if that one is not running on default port 443. So, if dev web server was running on port 8443, people would need to keep this in mind when working on their templates / redirects. On top of those, I can see 2 big risks: - if SSL-aware development server exists and easily available (just one command), people could start relying on it as it'd be much easier to set up than any other SSL website. That would be a big mistake, the dev server would be very insecure, missing lots of necessary features (and almost certainly having a self-signed certificate). - it'd probably only escalate things. If people get SSL-enabled dev server, they start asking why it does not support client-side certificates :) Just my 2 cents.

Hi, this is not very specific to Django as it is done using custom CSS (layout) and client-side JavaScript (sorting, filtering).

Most people need to solve other performance issues first before they find out that connection pooling would be a problem worth fixing.

Hi there,
there is probably more than one way to do it, but the one that comes
to mind is to write a simple custom filter, see
http://dpaste.com/167380/ (not tested)
then you could use:
{% if object_status|generic_length > 0 %} (or the pre-1.2 equivalent
using ifequal).
See
http://docs.djangoproject.com/en/1.1/howto/custom-template-tags/#howto-custom-template-tags
if you are not familiar with custom tags.
Please note that I have tested the code, so use it as a guidance only.
Cheers
Jirka

Re: need help in multi db
Hi Silaja, first, I'm going to guess that no one will be able to solve your problem. There are multiple reasons for it: - Multiple database support is in Django 1.2. You insist on using it on Django 1.1, without mentioning why you can't upgrade (the upgrade would make sense for any reader not knowing the context that only you currently do know) - the code written by Eric F. is an interesting hack for older versions of Django, but not too many people have probably used it, so there would be little experience with that. However, there is a problem: - * you have not specified what your problem was when you tried it * So, even people willing to spend their time helping you could not do it as they would not know how far you have gotten implementing it and what actually stopped you from succeeding. - you mentioned "i.e some of rows in some "x" table in one database and some of rows in "x" table in other database. i want to select which database used to add/retrieve the rows dynamically". This is quite complex and even the code from Eric's site will not help you much. If you make it working, it will lay the foundations, but you'd still be quite far from reaching your goal. I'm afraid that you need to give us more detail and the actual context before you can expect better answer than "upgrade to Django 1.2".

Re: How to check if I installed Django well?
Hi, if you've untarred the Django archive, you have a new directory called (probably) Django-1.1.1. Just go into that directory (in the command line, do "cd Django-1.1.1") and then run installation the standard Python way (for Python packages): "python setup.py install". It should run for a few moments and (hopefully) complete without errors. Then you will be able to remove the original package you've downloaded and the "untarred" directory. Diango will be installed in your Python's site-packages directory. To test, you can try: C:\> python >>> import django >>> django.VERSION (1, 1, 1) Hope it helps Jirka -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Django noob - static views or dynamic pages in web application?
Hi, sorry, but it seems that you need to take another look at the Django documentation to figure out how it works. Let me point out couple of things that were not exactly right in your email. First, Django is not a CMS (although there are CMS systems based on Django). Django is a *web development* framework. > URL is passed via a variable in urls.py No, Django takes the URL requested by the user and looks it up in a list of patterns defined in urls.py. If a match is found, Django calls the view function (typically locates in views.py) that was associated with that URL pattern. > which then locates a row in a database containing > the html code to send to a template. Typically, there is no HTML code in the database. Templates contain (most of) the HTML code. The data in the database is then used to complete the HTML code from templates. > create static pages inside views.py as well? I'd be surprised if someone had static pages in view functions. That's what templates are for (or, in some cases, specific Django functionality like flatpages) > I'm actually about to embark on a web application which will consist > of about 200 different page views and 12 different templates, all > performing some kind of in depth function. Do I try and integrate my > web app with a Django CMS or am I being an idiot if I create each of > these pages in views.py? Well, it's difficult to say without knowing more, but you'd typically want to create templates for those pages. The rest (data models, structure of urls.py and views) really depends on the web application you'd be trying to create. > I can't find any information on best practices with Django and not > sure where to start. Check out the overview: http://docs.djangoproject.com/en/1.1/intro/overview/ and then move onto the tutorial (on the same site).

Hi, email is not really suitable for sending large amounts of data. The fact that people use it that way is a bit sad, but you should not really follow their example. So, you're trying to send up to 200 MB via email. That's in fact some 270 MB, because binary data is base64 encoded in emails, typically (not always, but often). That is the reason for the memory problem. As Paulo pointed out, created a unique, temporary URL for downloading those images and send just the link to that URL.

Hi, yes, sure - Django is just python, so nothing prevents you from using signals. You'll have to step out of the usual request-response cycle, however. I have an internal project that uses "real" signals, based on libevent/pyevent. It uses Django ORM for data handling. All works nicely.

Re: set up database engine
>> how exactly set up the database engine as SQLight? The tutorial >> doesn't seem to tell us... Hi, if you edit the file "settings.py" in your project directory, all you need to do is to tell Django that you want to use SQLite3 and where you want the database (somewhere on your disk, where you have write permissions). As all necessary libraries are included in Python 2.5+, Django will automaticaly create the database for you once you run "manage.py syncdb". The database will be just one physical file.

Oops - sorry. I misread your email (another proof I should not reply to anyone before my first cup of coffee ;-) I'm not very familiar with j2ee syntax, but the logic seems a bit too heavy for a template, you might be better off implementing the logic in a view (hence, standard Python+Django), put the result in the context and only display the context in a template.

Hi, I did have this problem a few weeks ago. Did you doublecheck
your urls.py for Dajaxice-related links? What happens if you call
Dajaxice URL directly? (you should see requests for dajaxice.core.js
in your development server log).

Re: Tutorial database problem
Hi, you're creating your database file in /usr/bin which is intended for system executable files, not databases etc. It's highly likely that you don't even have write permissions there (unless you work using the "root" account which is a big NO-NO). Set your database file somewhere where you can write for sure, such as /home//test_db.db. You can easily find out if you have write permissions somewhere by using the "touch" command, i.e. "touch /home//test_db.db - it'll either create an empty file which means that this path is OK for your database, or give you an error.

Re: Django 1.4 - how to display a success message on form save
>> @Jirka - thanks. I saw something about the messaging framework and even
>> tried one example which did not work.
Using the messaging framework is actually very simple.
You need to enable the messaging framework (see the steps here:
https://docs.djangoproject.com/en/1.4/ref/contrib/messages/ )
In your template, you need this (I have that in my base template so
it's included in all pages):
{% if messages %}
{% for message in messages %}
{{ message }}
{% endfor %}
{% endif %}
Obviously, you'll need some formatting/CSS around it.
And in your views.py (or forms.py, ...)
from django.contrib import messages
if form.is_valid():
messages.success(request, 'Your form was saved')
And that's it!

Hi there,
you probably want to follow your {% if formations %} statement with:
{% for formation in formations %}
Check Django template documentation again - you're moving along the
right path, but your template is missing the loop across individual
formations.

Re: merge data from multiple models

From what you've described, I'd try to prepare the necessary data in a view (using caching, if possible at all), build the appropriate data structure to be displayed and then use the template layer to do a "dummy" display. Then you'd have the full power of Python at your disposal to perform the best access to your data and combining the models together into and array of items or a dictionary, depending on your need.

Re: invoking a funcion or module as root
Hi there, you definitely don't want to allow apache to setuid() to root as you've pointed out. You have a few options, probably the easiest one is to write a pair of scripts for each task you want your application to perform with root privileges. - the first script will only contain "sudo " - the second script should contain the necessary step(s) that need to be performed with root privileges. It should be simple to minimize chances for security issues Then you'd configure your sudoers file to allow apache process to call the "second script" *including the right set of parameters* (if applicable) with sudo permissions. You'd then call your "first script" using subprocess() call from your views.py (or whereever appropriate). (you could technically bypass the whole "first script", but it'll greatly improve readability if you do it this way, no one will have to read your python code to match it to your sudoers file if problems occur). Even better solution would be fixing your security model, having a web application perform high-privileged tasks on a system seems flawed in 99% of cases I can think of, but maybe you have a good reason why you need it that way.

Re: What is the easy way to install DJango?
It's easy to install Django on a Windows machine to test it out and develop code. Most of this is covered here: https://docs.djangoproject.com/en/1.4/topics/install/ In a nutshell, you need: - Python 2.x (2.7) - install it if you already have not done so - Django (start with a stable release e.g. 1.4, download link on the main Django page) - to install the downloaded Django package (covered in docs) - to find your "django-admin.py" (most likely in C:\Python27\Scripts) and use it to create your first project. - follow the official tutorial to learn the basics https://docs.djangoproject.com/en/1.4/intro/tutorial01/ It's pretty straightforward, most people have trouble locating the django-admin.py which is not on system PATH by default.

Re: django.contrib.markup deprecated in 1.5 - what's the alternative?
Hi Phil, incidentally, I was looking at this just recently. The contrib.markup was deprecated mainly due to security issues with 3rd party libraries that could not be fixed in Django itself and were compromising its security. For more, read https://code.djangoproject.com/ticket/18054 Can't tell you what the replacement is. I rolled up my own markup filter, but I only have a handful of trusted users for my web app so I don't have to be too concerned with trusting their inputs. You can copy the markup filter from 1.4 - just be aware of the security consequences. HTH Jirka -- You received this message because you are subscribed to the Google Groups "Django users" group.
