Re: "can't adapt" - mod_python, multiple interpreters, psycopg2
> > Problem is possibly with multiple interpreters and psycopg2 again, > > Why do you say that? The thread you refer to above doesn't talk about > mod_python, so do you have any extra evidence that support this claim? There was a bug in psycopg2 with Decimal data type that sometimes caused error like that: unsupported operand type(s) for *: 'Decimal' and 'Decimal' It was discussed on the list: http://groups.google.com/group/django-users/browse_thread/thread/091aa6c088f6c090 Similarly to "can't adapt" it was raised sometimes, after apache was running for few days, etc.. When error appears, restarting apache causes everything to work fine but only for some time and then again, errors are appearing. It was said that Decimal problem is caused by running psycopg2 with multiple interpreters, so thats why I think "can't adapt" might be the same thing. Exactly same place, same data entered in the form and after submit sometimes I get "can't adapt" and sometimes (after apache restart) everything works. Actually I found one thing in my code that shouldn't be there. I have FloatField in model but in ModelForm it is changed (manually in __init__) to DecimalField (in fact subclass that allows to use comma as a decimal separator). I suppose this change from Float to Decimal might be causing problems but it is strange that sometimes this works and sometimes don't. I have no full traceback because I can't reproduce "can't adapt" on demand. I only have last line of traceback that was sent to me by tester. I've already added logging of SQL yesterday but so far it didn't happen again. Also I've turned off debug mode so I'll have traceback e-mailed as soon as it strikes again.

Re: ViewDoesNotExist admin error.
Hi Chris, you may have a problem with your urls.py - check if you activated the admin site correctly (see http://www.djangoproject.com/documentation/tutorial02/#activate-the-admin-site - check if you have a pattern that catches /admin/ earlier on Do you use django-profiles? If yes: You do not use it properly: - It seems to not be installed correctly as django does not find the views module - "Recommended usage (for profiles/urls.py) is to use a call to ``include()`` in your project's root URLConf to include this URLConf for any URL beginning with '/ profiles/'."

Re: Adding ManyToManyField to Django models
Michael, Your opinion on this makes sense and in the end I will probably just go with the wrapper approach, since it probably won't make that much of a difference anyways. My biggest qualm is that I'm trying to put together a strong foundation for the projects I'm working on and feel like this is not the best, but yes I understand why it's like this. The other option you brought up about pulling the auth code will probably get hairy (as you already pointed out). The ModelInheritance stuff does look interesting! Thanks for the input. Discussing stuff like this always helps define the scope of the tools and how to use them... I'm sure I would've wanted to do something similar at some point in the future with my own models and it always helps to know what the boundaries are (at least for now).

Probably not such a great idea, since you aren't in control of any
updates that might happen to the User model. It's the standard problem
that if you change Django's source, that's fine, but then you have to
remember to make sure your changes work with any updates we might happen
to make to that code (we aren't about to add any new fields or anything,
but extra Python code might be added, for example).
A better approach would be to create your own many-to-many lookalike
structure by creating the intermediate model with foreign keys pointing
to User and whatever else you want (I guess also User in your case).
That model is entirely under your control and won't require changing
Django's source.

Malcolm

Re: Adding ManyToManyField to Django models
Michael; Think of it this way: the auth model is just one way to provide authentication into your architecture. It wouldn't make much sense to have too much more information about the person inside of this model. There is an effort to try to be able to extend models, but as far as I know it has been a difficult forge forward because databases don't work that way. The tie to another model is perfectly natural. As I am still thinking about this you wouldn't want to inherit the code anyway. If you want the cleanest implementation of your code you wouldn't want to have 2 different types (or the possibility thereof) of authentication. What I was saying in my first post is that you don't need to use any of the contrib applications. In fact, you can go ahead and look directly into the auth code and try to rewrite it with all the extras that you would like to put into it. I personally think you would be making yourself crazy just to save a table in your database, but if that is your cup of tea... Evert, take a look at the Model Inheritance branch: http://code.djangoproject.com/wiki/ModelInheritance it looks exciting, but a huge undertaking for whoever is working on it. I would be exciting to see and could save a lot of application code really.

Recovering from Postgres errors
When accessing a Postgres database from Django ORM without any explicit transaction management, any database query begins an implicit transaction which ends with the next save(). If the save fails due to a database error (e.g. integrity violation, timeout...) it raises an exception. At this point, any new queries will fail with the error psycopg2.ProgrammingError: current transaction is aborted, commands ignored until end of transaction block Basically the Postgres transaction is dead and has to be rolled back before any new queries can be executed. ISTM the Model.save() method itself could rollback the (implicit) transaction when there is an error, something like try: ... normal save code except DatabaseError: transaction.rollback_unless_managed() raise I have seen a bit of discussion of this in the list archives and Trac but I haven't found any good solutions. Wrapping every save() in a try block similar to the above seems very clumsy, as is wrapping every save() in an explicit transaction block. So, my questions are - how do others deal with this? - what is considered best practice, if anything? - does it make sense to alter Model.save(), or my own model's save(), as indicated above?

Re: Adding ManyToManyField to Django models
One thing I dislike about the approach that's being pushed by the community, which is to have a one-to-one relationship between auth.User and your own 'Profile' model (or whatever you want to call it) adding all the functionality and relationships to the user-created Model is a bit much. I mean yes it's convenient to use auth.User's prebuilt functionality, but if you're building for the future and want to start off in the right place, this method kind of starts your code in an awkward place. The data model with this approach just feels wrong... The right way to do it is to have two different tables link to eachother and have the database make the bindings for you. I know this simplifies the code a lot and that the DB will probably do a good job with this lookup, but still seems a little awkward to me... --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

(the difference between what the web archive shows and what my emails
shows, makes it somewhat hard to keep track of which messages you've
already seen, and where we exactly are in the problem solving, but
here goes anyway):
You initially had your PYTHONPATH set differently:
export PYTHONPATH=/path/to/python2.3/site-packages:/path/to/django/app
which is not the same as above. So which one should it be? What does
your regular shell have ('printenv PYTHONPATH')?
In the off-chance you've already got my other email, did you try that
(with the correct PATH settings, whatever those may be)? Ie, setting
the variables on the command line, not in the header of the crontab
file.

Cannot you use a model with a ForeignKey to whatever prebuilt model
you'd like to use? Cf using a home-made user model for authentication
that ties into the prebuilt User.
I would be curious, though, whether you can actually subclass a
prebuilt model; my guess is not, and that it messes up the database
tables, but that would be an interesting option otherwise.

the same features as are available to you in your models. So there is
no reason that you need to even install the auth system. You could
copy the code out of django.contrib.auth and customize it as you see
fit. The only thing is that code is tested and really complex and
might be doing things that you haven't even thought about, so you
might be looking at a project that is more complicated than you really
want it to be. The nice thing about auth is that it gives you a built
in function to add a profile to a user. This might be the best
solution for you. Check out the django book here:

problems with url tag
So, my urlconf is
urlpatterns = patterns('teleworker.clients.views',
(r'create/$', 'create'),
(r'modify/(?P\d+)/$', 'modify'),
(r'delete/(?P\d+)/$', 'delete'),
(r'page/(?P\d+)/(?P\w+)/(?P\w+)/$',
'list'),
(r'page/(?P\d+)/$', 'list'),
(r'^$', 'list'),
)
The list function is
def list(request, page=1, orderby='clientid', direction='forward',
filter=None):
When I try to use the url tag to get a url to this function, it only
matches the last line of the urlconf.
{% url teleworker.clients.views.list
page=1,orderby=clientid,direction=forward %}
What am I missing?
Thanks,
Mike

Re: Problems using cron to run a python script

Your script did run (you thought it completely failed), but -only- up
the 'import feedparser' part. Anything before that ('print sys.path')
actually worked fine.
Printing the sys.path is often quite useful to debug things like this.

Presumably the environment variables you can set in your cron file are
limited (to, eg HOME and EMAIL), which is why things don't work.
Assuming this cron works the same as other ones I know, you can set
the variables on the command line itself; that may work.
Try this entry in your cron (and remove the top part with the
environment variable settings):
1 * * * * PYTHONPATH=/path/to/python2.3/site-packages:/path/to/django/
app DJANGO_SETTINGS_MODULE=myproject.settings /usr/bin/python /path/
to/script/update_feeds.py > /path/to/script/update_feeds.log 2>1
(in case mailers mess up things: there are no line breaks in that line)
The log file part is still there to check if things go wrong, but if
it works fine, remove that part ('> /path/to/script/update_feeds.log
2>1')
If this seems a bit messy, you can alter the sys.path at the top of
your script, and set the DJANGO_SETTINGS_MODULE from there as well:
import sys
sys.path.extend(['/path/to/python2.3/site-packages', '/path/to/django/
app')
import os
os.environ['DJANGO_SETTINGS_MODULE'] = 'myproject.settings'
.
.
.
import feedparser
I prefer the first, since then the script itself is more portable (no
hardcoded paths etc).
I also came across this thread:
http://groups.google.com/group/django-users/browse_thread/thread/d77412f3bbbd1d1a/64d567aadbf4b3f9?hl=en=gst=cron#64d567aadbf4b3f9
which uses something slightly different (solution at the bottom). But
since this involves settings everything in your .bashrc (including
possibly silly greetings like 'echo "How are you today"), that may be
a bit overkill.
Let me know if it works.

You have been receiving help on how to print out what your script thinks the Python path is set to so that you can see that it is mosty likely incorrect and then go about fixing it. You are still at the "debugging what is wrong" phase, not at the "fixing it" phase. Work out what the Python path is set to (by printing it out, for example) and then you can set an environment variable to set it correctly.

The thread you refer to above doesn't talk about mod_python, so do you have any extra evidence that support this claim? What is the code doing before the problem occurs? Any exception includes a traceback and from that you should be able to work out which piece of your code is being executed prior to the problem. The next step is to work out what data is being passed in that is causing the problem and then tracing back where that came from. For example, after looking at a few tracebacks, if it's always triggered by the same spot in your code, you could put in a try...except block to catch this error and log the data you are trying to send to the database backend (log the type of the data as well, since if you see 1.23 you don't know if it's a float or a decimal or a string, often times). The information you've provided doesn't really have enough information to guess at the problem, unless you're really lucky and somebody with the same setup has seen the problem and already been through these debugging steps.

Neither 1 or 2 will help as multiple interpreters will still be used. If it really is some problem with interaction between multiple sub interpreters in the same process, possibly connected with psycopg2, one option may be to use mod_wsgi (www.modwsgi.org) instead and specifically use its daemon mode to delegate each Django instance to run in a separate set of daemon processes. If it is something to do with psycopg2 code not working in secondary sub interpreters, can also with mod_wsgi force each Django instance to run in main interpreter of their respective sets of processes. Alternatively, use a fastcgi, scgi or ajp based hosting solution. Graham --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

The string shouldn't ever be pass as None, so must be something else.
I believe the reason for the SCRIPT_NAME fiddle is that when you use
APIs within Django to construct a full URL, eg., for doing a redirect,
or perhaps for referencing static files, it will be wrong without the
fiddle. I don't use Django, so don't the specific functions that might
be the issue there. From memory I believe the problems show up quite
readily if you enable the admin interface. Some embedded URLs get sent
back as /admin instead of /my_app/foo/admin.

ANN: updater.py v0.5.0 -- Django project evolution utility
updater.py is a utility for applying and removing an ordered sequence of updates to a Django project: - Creates update skeletons. - Records and tracks update application/removal. - Provides some useful helper objects and functions. An update is typically used to evolve the database schema (preserving existing data) and is normally applied as part of a project codebase upgrade.

Re: mod_wsgi & trailing slashes on urls
Hi Graham,
Thanks for the useful reply. You're right, I skipped the general
configuration instructions and jumped straight to the Django specific
ones, which don't have examples for mounting at a sub-URL. It does
very clearly say on the general page that the trailing slash should be
omitted in that case - sorry for that.

Honestly, I think I prefer it without the trailing slash. That way,
with indexing enabled you get a directory listing (as you do for any
subdirectories below media), and a 403 otherwise.

I've been trying to avoid having to modify my url_patterns in a
mounting-specific way, so I opted not to use the workaround from
#2407. It was my understanding that this fix needs to be employed if
you're trying to host multiple Django sites under a single
VirtualHost. With the exception of the TypeError in my original post,
everything works as it should - Django essentially sees a cropped
version of the url in the address bar (i.e. with /my_app/foo removed),
so url_patterns shouldn't care that there's a url prefix.
Here is my urls.py:
-
urlpatterns = patterns('',
(r'^/?$',
direct_to_template, {'template': 'viewer.html'}),
(r'^upload/?$', views.upload),
(r'^accounts/login/$',login,
{'template_name': 'login.html'}),
(r'^accounts/logout/$', logout,
{'next_page': 'accounts/login/'}),
(r'^admin/',
include('django.contrib.admin.urls')),
)
-
I don't fully understand the SCRIPT_NAME problem, but I can surmise
why I'm getting the TypeError: mod_wsgi removes the /my_app/foo prefix
from the url in the address bar and feeds the rest to Django - in the
first url_pattern above, that would be an empty string. My guess is
that mod_wsgi is sending it None instead, causing the exception.
Simply matching something other than the empty string would avoid this
problem, but if my surmising above is correct, is that a bug in
mod_wsgi?
Many thanks,
Matt.

"can't adapt" - mod_python, multiple interpreters, psycopg2
Hi! I'm observing that "can't adapt" error appears on my Django powered site sometimes. After Apache restart everything is OK for few days and again... can't adapt appears. This is same thing as described there: http://groups.google.com/group/django-users/browse_frm/thread/b11f8fbcfb25aaa0/ed9376362ac30e41?#ed9376362ac30e41 In my case error is in: /var/www/django/django_sources/app1/test/django/django/db/backends/ util.py in execute, line 18 which turns out to be: return self.cursor.execute(sql, params) I have: 1. django from svn - newforms-admin branch, rev. 7106 (so it contains patch for unicode problems as described in the linked topic above) 2. Apache 2 with mod_python and multiple django instances (multiple python interpreters) 3. psycopg2 - version from svn that contains patch for Decimal as described there: http://www.initd.org/tracker/psycopg/ticket/192 Problem is possibly with multiple interpreters and psycopg2 again, so, as I can't find how, where and why this happens, the question is how can I change my environment to workaround this problem? I wonder about removing multiple interpreters issue by: 1. changing apache to MPM workers mode or 2. Using distinct VirtualHost for each application (so I don't have to set python_interpreter within VirtualHost directive) but I'm not sure if any of the above may help? Any ideas? -- Maciej Wisniowski --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Adding ManyToManyField to Django models
I was wondering if it's possible to add a ManyToManyField onto a
prebuilt Django model such as User... I know that it would look like
this if I were to have created the model myself:
class User(models.Model):
watch = models.ManyToManyField('self', null=True, blank=True)
I'm unsure how to add features to prebuilt models and wasn't even sure
if that was possible.
Thanks,
Mike.

Re: Oracle invalid environment variables
Richard, What versions of Oracle, cx_Oracle, and Django are you using? Apparently, this can be caused by an invalid NLS_LANG environment variable setting or an invalid NLS value in an ALTER SESSION statement. The Oracle backend automatically sets the NLS_LANG environment variable to ".UTF8" and issues an ALTER SESSION query to set the NLS_TIMESTAMP_FORMAT and NLS_DATE_FORMAT parameters. Both of these can be found in django/db/backends/oracle/base.py. I can see no problems with them, but you might try using the same settings in sqlplus to see if you can reproduce the issue there. You might also try asking your question on the cx_Oracle mailing list. Somebody there may have better insight into your problem.

Re: Problems using cron to run a python script
OK, I did what you instructed and checked the log file, which did contain the system path and the traceback about the "can't import module...". I see the paths specified don't contain the path to the feedparser module, which explains the error. My question is how do I add this path in the cron, especially since the script runs from the command line?

I believe that, because your PYTHONPATH will be set correctly from the command line; but possibly not from a default (basic) shell that cron uses. So, again, try putting those two statements at the top of your script, -before- the 'import feedparser' statement, and let cron do its job. You may need to redirect the output, eg 1 * * * * /usr/bin/python /path/to/script/update_feeds.py > /path/to/ script/update_feeds.log 2>&1 to get that output (I'm not sure how you got the error from the cron job; through email?)

Re: Problems using cron to run a python script
Hopefully, it will print the path before the import statement fails, and also log the error message that cron generates to a log. So it does matter if you print the sys.path, because that could tell you that the location of your feedparser module isn't on that path. I don't know about dreamhost, but is your cron running as a different user than you? If so, that could explain why you can run the command from the shell when you login vs. running it as cron.

Re: Problems using cron to run a python script
I'm sorry, but I still don't understand what this will do here. The cron can't run the script because it can't import the feedparser module or the models from my app. So it doesn't matter if I print the system path.

ManyToMany fields in database lookups
Hello, I have a curious problem with a complex filter in 0.96: Merchant.objects.filter(Q(categories_fr__name__icontains=s) | Q(categories_en__name__icontains=s)) this returns an empty queryset even when 's' is in categories_fr. Changing categories_fr__name with an attribute directly in the object has the same effect. It seems that a ManyToMany field with no elements nullifies the entire query. Is this a bug, or am I misunderstanding something? Thank you, Vincent. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

There are a few issues with many-to-many fields and empty results like this. The whole area has been given an overhaul in the queryset-refactor branch and so should be fixed on trunk soon-ish.

That's why I asked for the comments. :-) "Fuzzy" messages for not make it into the translation. They are not considered to be translated correctly, but they are not deleted, since they are likely to be "almost correct" and just need a small update. Part of normal translator operations is to search out any "fuzzy" messages and verify that they are either still correct (just delete the fuzzy comment, but do not delete the python-format bit) or update them and then remove the "fuzzy". This isn't anything special to Django, by the way. It's the way gettext-backed i18n support operates.

This is normal browser behaviour: they don't redisplay any file specified in file upload widgets to avoid phishing-style attacks. So Django doesn't bother sending it through.

Re: Flatpages
You were right about the 404.html template being required. And I found this ticket to help back up my problem: http://code.djangoproject.com/ticket/3335 It's a won't fix issue, but they put a comment in the code that was suppose to alert me that I needed the template, but I totally missed it, so that solution sort of failed me. Oh well, I'm sure most other people would have caught it. The strange thing is that I updated both servers to the trunk (0.97- pre-SVN-7193), and only one of them required the 404 template when DEBUG was set to False. So I'm guessing that it might be something external to Django, since my deployments on both boxes were almost identical. Both running on Apache with mod_python, and running all the same apps and very similar settings. Strange bug.

Re: Problems using cron to run a python script
I'm not sure where to print the path. Do I add that to the update_feeds.py? Or does this go in the cron itself? If I add it to the script, and then run the script from the command line, it prints what's on my python path and then runs the script as normal. But that's never been the issue.

Are you sure you haven't inadvertently introduced newlines into the
strings here? Can show us what the corresponding lines in the PO file
look like (include the comments before the msgid bit as well).
I'm assuming by "not working" you mean the string is being displayed in
English rather than, say, German. You're not saying the string doesn't
display at all, right?
My bet is that the last problems are human error, but I'd like to
understand them to see if we can bullet-proof this a bit more.

Getting file selected for upload to survive validation.
I have file uploads working using newforms.
However, if I run into validation errors on the form (say a mandatory
field is not filled), then when the form re-displays for the user,
the file they previously selected is no longer selected.
I've been reading through a variety of file upload suggestions, but
I've not found anything specifically targeting this problem.
Any suggestions as to what I'm not doing is appreciated.
Here's what my (simplified) model/view/template looks like:
Model:
class Note(models.Model):
category = models.ForeignKey(Category)
title = models.CharField(max_length=80, unique=False)
article = models.FileField(upload_to='articles/%Y_%m/',
null=True, blank=True)
View:
def add(request):
NoteFormClass = forms.models.form_for_model(Note)
if request.POST:
form = NoteFormClass(request.POST, request.FILES)
if form.is_valid():
form.save()
return HttpResponseRedirect('/')
else:
form = NoteFormClass()
response = render_to_response('notes/add.html',
{
'form': form,
})
return response
Template:
{{form.category.label}}*:{{form.category.errors}}{{cat_combo|safe}}
{{form.title.label}}*:{{form.title.errors}}{{form.title}}
Article
File:{{form.article.errors}}{{form.article}}{{form.article_file}}

Re: Problems using cron to run a python script
I ran into problems like that using cron and instead of trying to locate the real error in the paths (we were about to go live ...), I simple changed the cron line to read: 1 * * * * cd /path/to/script; /usr/bin/python update_feeds.py Why don't you try that and see if it helps...

If you took the plunge and switched to newforms-admin then you can override the changelist_view method in your ModelAdmin class. You'll need to replicate some of the behaviour of ChangeList from django.contrib.admin.main. Basically you'll want to check for search terms and hand off to the super method if any exist.

Blocktrans getting erratic
Hi everybody,
I really enjoy writing applications in Django but I ran into something
very strange while doing my first internationalized app. I'm using the
newforms-admin branch, revision 7192. All translations work fine,
except in these cases:
When I mark a string that spans multiple lines to be translated with
{% blocktrans %}, make-messages.py shows the string and compile-
messages.py works fine but the translation simply does not appear in
the output. This does not work:
{% blocktrans %}
This is a test string
{% endblocktrans %}
This, however, does:
{% blocktrans %}This is a test string{% endblocktrans %}
I found this - possibly related - bug, but it has been closed as
"worksforme": http://code.djangoproject.com/ticket/4535
This would be easy to work around, though. I'd just put everything in
one line. What's worse is the behaviour when using bound variables:
{% blocktrans with item.count as xyz %}This is the count: {{ xyz }}
{% endblocktrans %}
This works at first. When I add another variable, it stops working:
{% blocktrans with item.count as xyz and item.name as abc %}This is
{{ abc }}'s count: {{ xyz }}{% endblocktrans %}
It appars in the .po file just fine but again, the translated string
does not appear in the output. And the final straw: when I go back to
{% blocktrans with item.count as xyz %}This is the count: {{ xyz }}
{% endblocktrans %}
it doesn't work anymore! Does anyone have any idea what might cause
this behaviour?
After every change to the template I run
make-messages.py -a
then after redoing the .po file I do
compile-messages.py
and then restart the test server.
I'd be very grateful for any pointers, I'm running my head against the
wall here. It's probably something simple that I overlooked... but I
tried it about a million times.
Cheers,
Jonas

Optimizing code for a query
Hi, I need to optimize some code related to django db api. Imagine a model like this: class Languages( models.Model ): name = models.CharField( max_length=255 ) ... class Object ( models.Model ): name = models.CharField( max_length=255 ) languages = models.ManyToManyField( Languages, radio_admin=True ) I need to create a form to search Objects: def my_view(request): ... if request.POST: form = MyForm( request.POST ) if form.is_valid(): data = form.cleaned_data objects = Object.objects.all() if data['name']: objects = objects.filter( name__icontains = data['name'] ) if data['languages']: (1) ... I need to search an Object with name ILIKE %name% and with the languages specified in the form. data['languages'] looks like: [ u'1',u'2' ] the IDs of each language. I needs some help with the code that should be placed in (1). I thought: for language in languages: objects = Object.filter( languages__id = language) Is this code good or there is a better solution?

Hi Evan, The catch is that you _did_ create content - you just don't know that you did because it happens in the background. When you run syncdb, various triggers are fired that stimulate the creation of certain initial data. Of particular interest in this case are the content types. Each model you have in your project generates a content type so that the models can be referred to in a generic manner by other parts of Django. There isn't really any way to control the content types that are allocated. As a result, if you change the applications that are installed, or the order in which they are installed, the content types can change. If you generate a fixture on an old database, modify the installed apps, re-synchronize your database, then load your fixture, the old content types can potentially cause a conflict - the error you are seeing is one such potential problem. The only real solution at present is to avoid serializing content types whenever possible (i.e., by not dumping the contenttypes application). If your fixture already has content types, manually delete them from the fixture before loading. This is a known crusty area associated with fixtures. Unfortunately, it isn't a trivial problem to fix. Suggestions on how to improve this aspect of Django are most welcome.

edit_inline in ModelForms
Hi,
I've been looking and searching for the last days to find out how i
could fix that, but I don't get around. I did read the newforms-admin
fieldset.py stuff, also the edit_inline_stacked.html template, but I
still don't figure it out.
What i would like to do is, to have 2 Models within one form.
The model is:
#
class Album(models.Model):
artist = models.ForeignKey(PortalUser)
title = models.CharField(max_length=100)
slug = models.SlugField(prepopulate_from=("artist", "title"))
genre = models.ManyToManyField(Genre,
filter_interface=models.HORIZONTAL)
def __unicode__(self):
return self.title
class Admin:
list_display = ('title', 'rating_stars', 'artist',
'release_date')
list_filter= ('label', 'release_date')
ordering = ('-release_date',)
search_fields = ('title', 'label')
fields = (
(None, {'fields':('title',)}),
('Album informatin', {'fields':('cover', 'language',
'release_date', 'genre')}),
)
class Track(models.Model):
artist = models.ForeignKey(PortalUser)
title = models.CharField(max_length=100, core=True)
file = models.FileField(upload_to="/", core=True)
album = models.ForeignKey(Album, edit_inline=models.TABULAR,
num_extra_on_change=1, num_in_admin=10)
def __unicode__(self):
return self.title
class Admin:
list_display = ('title', 'album', 'artist')
search_fields = ('title', 'genre', 'artist')
list_filter = ('language',)
#
and I use the following form:
class AlbumForm(forms.ModelForm):
class Meta:
model = Album
with this view:
login_required
def add_or_edit_album(request, success_url='',
form_class=AlbumForm,
template_name='music/album_form.html'):
success_url = '/artist/%s' % (request.user.username)
if request.method == 'POST':
form = form_class(data=request.DATA, files=request.FILES)
if form.is_valid():
album = form.save(commit=False)
album.artist = request.user
album.save()
form.save_m2m()
return HttpResponseRedirect(success_url)
else:
form = form_class()
return render_to_response(template_name,
{ 'form': form },
context_instance=RequestContext(request))
what happens, when I call the template is, that only the album form
shows up, but it does not contain the track slots. When I try to call
the TrackForm (created the same way as the Album Form) I do get a drop-
down box for the albums. Does someone know a way how to solve this?
I use the current svn version from django.
Many thanks!
Tom

django-dataplot 0.5
I just released a new version of my django-based plotting framework to
http://sf.net/projects/django-dataplot. Here's one example of making a
plot in an app that tracks goals in a series of soccer games:
from dataplot import plotmodels as models
class Player(models.Model):
name=models.CharField(max_length=100)
goals_per_game=models.FloatField()
win_percent=models.FloatField()
MANAGER_DATAPLOTS=[
(R.SquareScatter,{'get_plot_args':{
'x':'goals_per_game',
'y':'win_percent',
'ann':'name',
'main':"Does scoring a lot of goals make you win?"
}})]
Django-dataplot takes care of the rest so you can just put this in your
template:
{{player.objects.SquareScatter.to_html}}
and a scatterplot image will show up on the web page, representing each
player as a point labeled by name, with average goals_per_game on the x
axis and win_percent on the y axis. So you can use the plot to easily tell
if high scoring means high likelihood of winning.
There are many other examples, and the system is quite extensible, so I
hope it will be able to help out some people in the community. I would
appreciate anyone who is interested in making plots/graphs on
Django-backed websites to download django-dataplot from sourceforge and
email me back with feedback and suggestions. Thanks for your time!
Sincerely,
Toby Dylan Hocking

Oracle invalid environment variables
Hello Django Users, Althought this is probably not a specific django error, i hope someone can point me in the right direction. I developed a application on a development server where everything works just fine. server specs ( development server ): - Linux version 2.6.9-22.0.2.ELsmp ([EMAIL PROTECTED] bc1-6.build.redhat.com) - Intel Xeon 3 ghz When we migrated the application to the production server server specs: - Linux version 2.6.9-55.ELsmp ([EMAIL PROTECTED] bc2-14.build.redhat.com) - Intel Xeon 2.7 ghz We got the following Oracle error: ORA-12705: Cannot access NLS data files or invalid environment specified I googled on this error and it says there might be a issue with deleting sessions. This error occurs random so i really don't know where to look. any help would be appreciated. regards, Richard Mendes --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.
