Re: filtering in a template based on foreign key or query params
Oh, the answer here was to use the regroup template tag. Thanks Magus.

None model error handling in view
Hi all, How to handle errors from different modules, for example CSV or DATETIME in view? I am trying to parse CSV content in my view after an uplod a file by user. def my_view(request): ... try: for row in csv.reader(request.FILES['file']): for i in range(0, len(row)): if not row[i].strip(): row[i] = 'None' except csv.Error, e: csv_error = e In console scripts CSV exception works very well, but in Django can't get it. The same story with DATETIME or some standartd python operators: try: discount = int(row[5]) except ValueError: csv_error = 'Bla Bla Bla' How to handle this stuff? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Per-Test Caching?
Use database backend for caching while testing. Tests create temporary database so it will have no side effects.

Per-Test Caching?
Hi, I have a Django app that relies heavily on caching. I'd like "./manage.py test" to run on its own test cache instance (so it doesn't see keys from previous runs / other development / etc). I can write code to set up the cache appropriately, but, where can I put it s.t. it runs before (and, ideally, after, for cleanup purposes) all test cases?

Re: global name 'Image' is not defined
This is the definition of NameError:
"Raised when a local or global name is not found. This applies only to
unqualified names. The associated value is an error message that
includes the name that could not be found."
I don't know what I doing wrong!

Re: global name 'Image' is not defined
I think you have a typo in this line, May be you write `Image.new` with
lowercase "L" not uppercase "I" as first char.

You should not !-)

What the browser receive is an HTTP response. IOW : text. You'll find a
very exhaustive description of what's an HTTP response in the HTTP rfc:
http://www.w3.org/Protocols/rfc2616/rfc2616.html
> Then how can i set the value of a single textbox placed in between a
> big form?
for which definition of "setting the value" ?
If what you mean is : "how do I change the "value" attribute of an HTML
form on the browser using Javascript", then you're definitively on the
wrong newsgroup.
> If i use a loop like below
> {% for field in form %}
> {{ field.name }} {{ field }}
> {% endfor %}
You'd getter better results using form.as_p IMHO.
> The row field name is displaying rather than the verbose name.
Of course, that's what you asked for.

Not necessarily, but that's indeed the most common case.
> When we using ModelForm, how can we get the "name" value for each
> controll?
How would this information help you setting the value using javascript ?
> Hop you understand what i meant.
> Sorry for my poor English...
Well, hope you'll pardon me, but I don't know for sure if you are
confused wrt/ how HTTP work or if it's just a language problem. If you
really feel your English is too limited to clearly explain your problem,
you should perhaps find someone around you that may help you rewriting
your question.

Re: Submit button names are not showing up in request.POST
I found the problem, but it wasn't Django related. I was using javascript to disable the submit buttons once the form was submitted. This was done to prevent multiple clicks of a submit button. Interestingly enough, making the buttons disabled also prevents them from showing up in the submitted form variables. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

django tagging + multilingual doesn't work
I'm writing about my problem again, to bring your attention I've made
my long report short:
I'm using django-tagging and django-multilingual applications in my
project. Tagging worked ok until I've added multilingual application
to the
project, and now I don't know if problem is in tagging or in
multilingual.
Here's model class:
class Script(models.Model):
pub_date = models.DateTimeField()
slug = models.SlugField(max_length=120)
tags = TagField()
class Translation(multilingual.Translation):
headline = models.CharField(max_length=200)
description = models.TextField()
body = models.TextField()
class Meta:
ordering = ('-pub_date',)
Then I'm starting manage.py shell command in my project folder and
enter next few lines:
my_tag = Tag.objects.get(name='sometag')
TaggedItem.objects.get_by_model(Script, my_tag)
error appeares - OperationalError: (1054, "Unknown
column'scripts_script.id' in 'on clause'")clause'
all application are at latest svn versions.
Thanks, in advance, for your help.

Re: How to order a list with a self-referential foreign key? (a category list)
I've found what I was looking for, and it turns out it's not simple at all. Storing hierarchical information in a database is challenging and there are several SQL techniques that can be applied to the problem. There are a few good Django implementations out there, including django-categories, django-mptt, and django-treebeard. I chose to use some of the code from django-categories because it seemed the most straightforward, though it hasn't been touched in a while and needed some tweaks to get around backwards-incompatible changes with Django signals. I hope this helps point someone else in the right direction. I've got it (mostly) working, and if anyone needs advice on doing it with their own projects, feel free to send me a message. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: windows can't find django-admin.py
And finally to get arguments to be passed correctly, one needs to adjust the file association settings. Open MyComputer, Tools->FolderOptions, FileTypes, find "PY" in the list, select Advanced, select "open" and Edit. Change the Application Used.. to "C:\Python25\python.exe" "%1" %* Change the python.exe path for your system as required.

If you try runserver with --noreload and don't see your __init__.py code getting called twice than that is what is causing it. You generally want to run with the autoreloader, though, so that code changes are automatically picked up by the running server (unless you are running under a debugger, where the reloading prevents breakpoints from working).

That mod_python.so has embedded static module and you can shared being linked in here can cause crashes. Haven't seen this variation of problem before, but see: http://code.google.com/p/modwsgi/wiki/InstallationIssues This describes issues with use of static and shared library for Python at same time when using mod_python and mod_wsgi together. In short, rebuild mod_python so it uses shared Python library instead. Maybe also consider using mod_wsgi as well. It will not solve the problem, but arguable better solution these days. :-) Graham > libpthread.so.0 => /lib64/libpthread.so.0 (0x2aad165ef000) > libc.so.6 => /lib64/libc.so.6 (0x2aad16809000) > libresolv.so.2 => /lib64/libresolv.so.2 (0x2aad16b5c000) > libdl.so.2 => /lib64/libdl.so.2 (0x2aad16d72000) > libcrypt.so.1 => /lib64/libcrypt.so.1 (0x2aad16f76000) > libgssapi_krb5.so.2 => /usr/lib64/libgssapi_krb5.so.2 > (0x2aad171ae000) > libkrb5.so.3 => /usr/lib64/libkrb5.so.3 (0x2aad173dd000) > libcom_err.so.2 => /lib64/libcom_err.so.2 (0x2aad1767) > libk5crypto.so.3 => /usr/lib64/libk5crypto.so.3 > (0x2aad17872000) > libz.so.1 => /usr/lib64/libz.so.1 (0x2aad17a98000) > libutil.so.1 => /lib64/libutil.so.1 (0x2aad17cac000) > libm.so.6 => /lib64/libm.so.6 (0x2aad17eaf000) > /lib64/ld-linux-x86-64.so.2 (0x0039a2c0) > libkrb5support.so.0 => /usr/lib64/libkrb5support.so.0 > (0x2aad18133000) > libkeyutils.so.1 => /lib64/libkeyutils.so.1 > (0x2aad1833b000) > libselinux.so.1 => /lib64/libselinux.so.1 (0x2aad1853e000) > libsepol.so.1 => /lib64/libsepol.so.1 (0x2aad18756000) > > and: > > /usr/lib64/libldap.so: > liblber-2.3.so.0 => /usr/lib64/liblber-2.3.so.0 > (0x0039ad40) > libresolv.so.2 => /lib64/libresolv.so.2 (0x0039ae80) > libsasl2.so.2 => /usr/lib64/libsasl2.so.2 (0x0035dd20) > libssl.so.6 => /lib64/libssl.so.6 (0x003b6960) > libcrypto.so.6 => /lib64/libcrypto.so.6 (0x0039a380) > libc.so.6 => /lib64/libc.so.6 (0x0039a3e0) > libdl.so.2 => /lib64/libdl.so.2 (0x0039a460) > libcrypt.so.1 => /lib64/libcrypt.so.1 (0x0035daa0) > libgssapi_krb5.so.2 => /usr/lib64/libgssapi_krb5.so.2 > (0x003b68a0) > libkrb5.so.3 => /usr/lib64/libkrb5.so.3 (0x003b68e0) > libcom_err.so.2 => /lib64/libcom_err.so.2 (0x0039ad80) > libk5crypto.so.3 => /usr/lib64/libk5crypto.so.3 > (0x003b6860) > libz.so.1 => /usr/lib64/libz.so.1 (0x0039a4e0) > /lib64/ld-linux-x86-64.so.2 (0x0039a2c0) >

What about python logging? Anything sent to stdout in mod_python will end up in the Apache error logs, at least eventually. The problem is that it is buffered and it requires explicit flushing. To avoid having to modify code, you may be better off using mod_wsgi. In mod_wsgi output to stdout will actually generate an error by default, because portable WSGI applications should not output to stdout and some WSGI hosting mechanisms use stdin/stdout. One can disable this restriction in mod_wsgi through a configuration directive or by reassigning sys.stdout to be sys.stderr. In general, outputing debug to stdout in web applications is a bad idea. You should instead output them to stderr instead. For more information see: http://code.google.com/p/modwsgi/wiki/ApplicationIssues#Writing_To_Standard_Output > 2) Is there a good way in Django to put startup code when deployed in > Apache that only gets run once per server restart? I build some > indexes that are used by my Django apps but it only needs to be done > at initialize time once. You can put code in settings file. Do note however that this will be executed once per process created by Apache. Since Apache is multiprocess this can therefore happen many times in life of Apache instance. Apache can also recycle processes within lifetime of Apache instance. With mod_wsgi, things are perhaps again more flexible as you can put startup code in WSGI script file rather than having to put it in settings file. Also, mod_wsgi allows you using mod_wsgi daemon mode to delegate application to single daemon process if having initialisation done more than once is a problem.
