Strange 404 error in admin
Hi, This is a strange case. I have a simple blog entry model which can be edited in the admin, from the URL that looks like: http://www.example.com.au/admin/blog/entry/52/ Now, what is strange is that the link above returns a 404. Same with the entry id=51. Yet, entries with id=51,52 do exist. - All other entries (with id < 51) work fine in the admin. - All entries (including id=51,52) work fine on the front end. - Everything works fine when I test it locally on my computer with a replica of the online database. I've never come across something like that, and I'm not sure where to look to debug this. Would you have some hints to suggest? Thanks a lot for your help, Julien PS: It is using a quite old version of Django, a trunk revision between 0.96 and 1.0. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

protect from brute force attacks on login
Hi all, I'm using django-registration to handle logins, registrations etc. It is very handy and easy to set up, but allows unlimited login attempts, and thus people can brute-force any django-application! So far I've been using fail2ban to ban users that brute force passwords. I would be interested to hear how you handle this from within django! Are you aware of some patch/code or blog entry where I can find more information?

Re: Upload ZIP-File into Database
Hi Karen, I didn't mind to start a quiz... The problem is that in the code above django seems to control if the ZIP-File contains Images. I'm not sure but when I take a ZIP-File which contains Images there is no problem, but when I take my ZIP-File I always get the error: BadZipfile - File is not a ZIP-File. I've also looked at the code from django-photologue, but there is the same problem. I don't figure out where this 'Image-Check' is defined... As I told before my ZIP-File contains five .lst-Files which contains the data for my database. How I can I tell django to expand these files, read them one by one and fill my database with the values?

What were you expecting to see? This output indicates that you are using the default __unicode__ method for the Poll object, which won't be printing any detail of the object itself - just the fact that it is a Poll object. If you retrieve an individual object from the list that has been returned, you will be able to interrogate the individual fields of that object, and you should find that they hold unicode data. Alternatively, you can provide a definition for the __unicode__() method for the Poll class, and it will print whatever you desire (for example the poll title, not just "Poll object") > Can you imagine what they problem might be? No problem here - just a misunderstanding of usage. I'm guessing you're new to Python - by way of guidance, this isn't a Django-specific feature.

Troubles with unicode in django-trunk
Hello, I downloaded the 1.0.2 version of django to my ubuntu 8.10 box and began the tutorial. I got as far as adding the unicode print definitions for poll and choice, and then saw no difference between afterward : In [2]: Poll.objects.all() Out[2]: [] is still what I saw. So I scrubbed the 1.0.2 and got the svn version, but there is still no difference. I removed and relinked the /usr/lib/python2.5/site-packages/django directory and /usr/lib/django-admin.py file as recommended. I really need unicode to work.

Django isn't an application server - it's a set of libraries that lets you write web applications. Those applications are then served using a mod_python interface (as well as mod_wsgi interfaces). I can't speak with absolute authority on Turbogears, but I'm fairly certain the same is true there. In order to deploy a Django application, you're still going to use mod_python (or mod_wsgi). You obviously have some concerns about Django compared to something else you are familiar with (PHP?). Perhaps if you explain your specific concerns, we may be able to address them.

Re: mod_python vs. Django?
Think about Django as Cake PHP, Symfony, Code Igniter, etc from the PHP scene.

Perhaps if you explain your > specific concerns, we may be able to address them. The mod_python module also supplied higher level handlers which incorporate a URL dispatcher and templating mechanisms. Thus for simple stuff it can be used to construct applications in its own right and isn't just a jumping off point for larger self contained systems such as Django. For new applications, anyone would be well advised though to use these distinct systems rather than welding themselves to the mod_python specific handlers. By using a separate system they ensure there application is portable to different hosting mechanisms, which will be good protection given that mod_python is dying a slow death and is unlikely to be ported to Python 3.0.

Re: Best practice question: subclassing external app components
in my own setup I have a few apps where it might go:
globalapp
- a collection of misc snippets, classes and utilities that I use on every
project I work on
{website}
- the specific website if this code will not be reused
accountz
- views, forms related to my own styles of login utils, registration etc.
things from here are used on every site I work on
3 would be the best choice I think.
for capitalizing the labels on fields you should try just doing css

Re: Subclass/Inline Problem - should I be able to do this?
All inline models need to have a ForeignKey pointing back to the base model. In your case you need to declare a ForeignKey field from Gallery model to Business model, what you've did instead is you've created foreign key to parent class (Directory). Try this: class Directory(models.Model): name = models.CharField(max_length=60) class Business(Directory): anyfield = models.CharField(max_length=60) class Gallery(models.Model): directory = models.ForeignKey(Business), pic = models.ImageField(upload_to='pics') On Feb 6, 9:56 pm, phoebebright wrote: > Here is my model: > > class Directory(models.Model): > name = models.CharField(max_length=60) > > class Business(Directory): > anyfield = models.CharField(max_length=60) > > class Gallery(models.Model): > directory = models.ForeignKey(Directory), > pic = models.ImageField(upload_to='pics') > > This is admin.py > > class Galleries(admin.TabularInline): > model = Gallery > > class DirectoryAdmin(admin.ModelAdmin): > > inlines = [ > Galleries, > ] > > admin.site.register(Business,DirectoryAdmin) > > This is the error I get in admin. > > Request Method: GET > Request URL: http://127.0.0.1:8000/admin/town/business/add/ > Exception Type: Exception > Exception Value: > > has no ForeignKey to 'towns.town.models.Business'> > > If I take out the inlines bit in admin.py and just have > > admin.site.register(Business) > admin.site.register(Gallery) > > Then it works as expected. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Sorry, I am new to python and I guess you hadn't bothered to read the elementary tutorial that I was following. I should have been more specific: http://docs.djangoproject.com/en/dev/intro/tutorial01/?from=olddocs about 7/8s' of the way down the page : Wait a minute. is, utterly, an unhelpful representation of this object. Let's fix that by editing the polls model (in the polls/models.py file) and adding a __unicode__() method to both Poll and Choice: class Poll(models.Model): # ... def __unicode__(self): return self.question class Choice(models.Model): # ... def __unicode__(self): return self.choice If __unicode__() doesn't seem to work If you add the __unicode__() method to your models and don't see any change in how they're represented, you're most likely using an old version of Django. (This version of the tutorial is written for the latest development version of Django.) If you're using a Subversion checkout of Django's development version (see the installation docs for more information), you shouldn't have any problems. If you want to stick with an older version of Django, you'll want to switch to the Django 0.96 tutorial, because this tutorial covers several features that only exist in the Django development version. It's important to add __unicode__() methods to your models, not only for your own sanity when dealing with the interactive prompt, but also because objects' representations are used throughout Django's automatically-generated admin. So it was in response to that advice that I "saw he installation docs for more information" and didn't find the relief spoken of and so wrote here.

Without seeing your code, its almost impossible to determine the cause of your problem. My initial guess would be that one of three things has happened: 1) You haven't actually saved the models.py file where you have defined the __unicode__() methods. An obvious error, but a surprisingly common one. 2) You haven't restarted your python shell - you've just continued working with an old shell. You need to start a new Python shell session to force the models.py file to be reloaded. 3) You've misspelled __unicode__ in your models.py file. Most likely culprit here - using single underscores rather than double underscores in the method name. The method needs to be called _ _ unicode _ _ (self). If you have used a different name, you won't see an error (since the alternate name will be a valid Python method name) but it won't generate the output you expect. If you post your example code as it currently stands, we may be able to provide more assistance.

Changing Image in admin deletes the rest - expected behaviour?
Model: class Car(models.Model): ... lots of fields ... pic1 = models.ImageField(blank=True, upload_to='pics') pic2 = models.ImageField(blank=True, upload_to='pics') pic3 = models.ImageField(blank=True, upload_to='pics') pic4 = models.ImageField(blank=True, upload_to='pics') In admin, if I change the content of one pic it blanks the rest. Is this expected behaviour? Be great to add a bit more file handling to the admin side. The ability to delete a pic for example. When I get more skills I will try writing a custom field class for where there is only one file/ image per database entry and in this case it will handle automatic deletion of files when the record is deleted or changed. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: How do I add a Custom ID Field that increments?
Thanks Guys, Will, your snippet was exactly what I was looking for - thanks for that.

I'm sorry. I didn't mean to accuse you of negligence at all! I just
meant that as an experienced python programmer you might have had a
different entry point to django than I did. I was unaware that you are
of the core. My apologies in any case.

Yes. Just the sort of mistake I'm prone to make too. But not this
time.

I actually thought of that one myself after the first or second run.

I've double-checked and that's not the case. I had cut and pasted the

You're only supposed to have one class Poll(...), class Choice(...), etc.
line. When you add a method like __unicode__ or was_published_today, simply
append it (properly indented) to the existing class Poll(...) you already
have. Do not add another class Poll(...) line.

FreeBSD 6.2 trouble using postgresql_psycopg2
Hi there! I have py25-django-1.0.2 port installed on FreeBSD. While
following this tutorial:
http://docs.djangoproject.com/en/dev/intro/tutorial01/#intro-tutorial01
I've reached the line that says
DATABASE_ENGINE -- Either 'postgresql_psycopg2', 'mysql' or 'sqlite3'.
Other backends are also available.
So I set DATABASE_ENGINE = 'postgresql_psycopg2' in my settings.py,
but alas, manage.py runserver spits this:
Validating models...

This is no surprise, as django always attempts to install databases/py-
psycopg, and not databases/py-psycopg2, since the former is hardcoded
in its port Makefile. Any ideas?
Thanks.

Any ideas? Django's documentation lists all available values for the DATABASE_ENGINE setting: http://docs.djangoproject.com/en/dev/ref/settings/#database-engine It also covers the difference between the two PostgreSQL options, and tells you what to specify to use psycopg version 1 instead of psycopg version 2: http://docs.djangoproject.com/en/dev/topics/install/#database-installation Or, you could install the psycopg2 port and then use that. -- "Bureaucrat Conrad, you are technically correct -- the best kind of correct." --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

I don't have my copy of Practical Django Projects handy but it looks like
you wired up the URL incorrectly, specifically the URL you are reversing to
doesn't have a regex that actually captures any of those fields, I would
take a look at the URL conf James shows and see how it differs from yours.

Apache, Django configuration
Hi All, I use mod_python to run Django on Apache. But, I notice all of the urls that Django received are not correct. In deed, the "/" after the domain name is truncated. e.g. http://localhost/admin/ , Django receives "http://localhostadmin"; Why this happen?

Problem reopening files
Hi,
I've written a form ImageField that is cropable with the help of a
javascript cropper. In the course of saving the cropped image, I have
to reopen the image file a couple of times in different modes in the
"clean"-method of the ImageField. Unfortunately, despite the docs
saying something different[1], the file isn't reopened with a
different mode:
In [1]: from django.core.files import File
In [2]: f = open('test.txt', 'r')
In [3]: df = File(f)
In [4]: df.mode
Out[4]: 'r'
In [5]: df.open(mode='w')
In [6]: df.mode
Out[6]: 'r'
Am I doing something wrong here?
Regards,
Benjamin

The problem here seems to be caused by setting primary_key=True on one of
the fields in the model that inherits from another. You can see it using
just these simple models:
class BaseM(models.Model):
base_name = models.CharField(max_length=100)
def __unicode__(self):
return self.base_name
class DerivedM(BaseM):
customPK = models.IntegerField(primary_key=True)
derived_name = models.CharField(max_length=100)
def __unicode__(self):
return "PK = %d, base_name = %s, derived_name = %s" % \
(self.customPK, self.base_name, self.derived_name)
and manage.py shell (output reformatted for readability):
Python 2.5.1 (r251:54863, Jul 31 2008, 23:17:40)
[GCC 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
(InteractiveConsole)
>>> from ttt.models import DerivedM
>>> from django.db import connection
>>> DerivedM.objects.create(customPK=44, base_name="b1", derived_name="d1")
>>> DerivedM.objects.all()
[]
>>> connection.queries[-1]
{'time': '0.006',
'sql': u'SELECT
`ttt_basem`.`id`,
`ttt_basem`.`base_name`,
`ttt_derivedm`.`basem_ptr_id`,
`ttt_derivedm`.`customPK`,
`ttt_derivedm`.`derived_name`
FROM `ttt_derivedm` INNER JOIN `ttt_basem`
ON (`ttt_derivedm`.`customPK` = `ttt_basem`.`id`) LIMIT 21'}
>>>
The ORM is joining the two tables and attempting to match the
manually-specified custom PK from the child table to the auto-generated id
in the parent table, which results in finding nothing. I do not know if
specifying primary_key=True on a field in a child table is just not allowed
(in which case it should probably be flagged as an error during validation)
or if the ORM should be handling this properly. I do not see any ticket
open that describes this case; you might want to open one since it seems
something ought to be changed here to either report an invalid model
definition or handle this case properly.

Question about INNER JOIN vs LEFT JOIN and some strange issue when model binds to in self through many-to-many relationship.
At first step I will describe my models:
class Meter(models.Model):
id = models.IntegerField(primary_key=True)
some stuff here...
collector = models.ManyToManyField("self",
through='MeterCollector', symmetrical=False)
class MeterCollector(models.Model):
meter = models.ForeignKey(Meter, related_name='meter_id')
collector_node = models.ForeignKey(Meter,
related_name='collecotor_node_id')
def __unicode__(self):
return u'meter id: %s; collector node id: %s;' %
( self.meter_id, self.collector_node_id)
class Meta:
db_table = 'meter_to_collector'
class MeterSspec(models.Model):
id = models.IntegerField(primary_key=True)
meter = models.ForeignKey(Meter)
sspec = models.ForeignKey(Sspec)
..some stuff...
Everything works fine until I use filter like this in view.py:
meter_list = Meter.objects.all().filter(meter__metersspec__sspec =
sspec_id)
I expect something like "Give me all meters that have sspec_id = 1",
so my custom query will be:
SELECT `meter`.`id`, `meter`.`description` FROM `meter` LEFT JOIN
`meter_to_collector` ON (`meter`.`id` =
`meter_to_collector`.`collector_node_id`) LEFT JOIN `meter` T3 ON
(`meter_to_collector`.`meter_id` = T3.`id`) INNER JOIN `meter_sspec`
ON (`meter`.`id` = `meter_sspec`.`meter_id`) WHERE
`meter_sspec`.`sspec_id` = '1'
But django gives me something like this:
SELECT `meter`.`id`, `meter`.`description` FROM `meter` INNER JOIN
`meter_to_collector` ON (`meter`.`id` =
`meter_to_collector`.`collector_node_id`) INNER JOIN
`meter` T3 ON (`meter_to_collector`.`meter_id` = T3.`id`) INNER JOIN
`meter_sspec` ON (T3.`id` = `meter_sspec`.`meter_id`) WHERE
`meter_sspec`.`sspec_id` = '1'
There are 2 common problems:
1) How can I force django to use LEFT JOIN ???
2) Genreal problem: Im wondering why django joins meter_sspec with
meter_to_collector (T3) and not with meter???
So, is there any way to do it without custom sql query ?

This is really difficult to read like this. Next time if you post
post, please put it on a pastebin site like dpaste.com . This will
make my life a lot easier.
My bet is when you look at the post information coming across the wire
you aren't going to see any of the information you expect. First off,
where does the 'forms' variable come from? The best way to check the
post/get requests is with a product like Firebug or Fiddler. You can
see what is going with your post and make sure that it matches what
you think it should be.
Take a look at that information, hopefully it will become clear what
is wrong when you look at it like that.

urlize
Hi, I have written a django app that manages 'change requests' (and approvals) for IT infrastructure changes in our company, and I am using the urlize filter when displaying certain fields (like description of change, test plan etc). This is so that if a user puts a link to documentation for a system / change then it shows up as a link. This works reasonably well - in fact too well in some cases. As you can imagine some of the descriptions contain lists of domains, and these are all getting changed to links. I have logged a feature request for my next release of my app to sort the problem out (probably by wrapping lists of domain's in tags, then writing a custom filter to urlize stuff that is not surrounded by these tags), but I was wondering if this might be something that other django users would want, and if so, is it worth me raising a feature request to get the functionality put in to the django urlize filter? Or perhaps someone has a better suggestion for how to get around this problem? Em --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

"BadZipfile - File is not a ZIP-File" is not a string contained anywhere in the code you posted so doesn't help pinpoint where the code you posted is running into trouble. Furthermore, from a brief look at your code I don't see where you are doing anything to even try to iterate through the files contained in the zip file and do something with them (your code rather seems to be trying five different ways to 'test' whether it's gotten a valid zipfile?). I've not used the python ZipFile support myself, but looking a this: http://code.google.com/p/django-photologue/source/browse/trunk/photologue/models.py#194 I can see there is a loop 'for filename in zip.namelist():' that then extracts the data for individual files via 'data = zip.read(filename)', and does stuff with the data. I don't see anything like that in what you have -- Django is not going to do this sort of processing automatically for you, you have to write the code to do it. And if your problem is you do not know how to manipulate zip files in Python, the right place to ask about that would be someplace like comp.lang.python, not here. There is nothing Django-specific about manipulating zip files in your application; ZipFile is provided by Python, not Django. Perhaps you just haven't gotten that far, though, since the message you report sounds like the basic testing of "is this a valid zipfile" is failing. In which case one thing that would be nice to know is can you test/validate the zip file read from the file system (perhaps using the python shell) using code similar to what you have? If that too is failing, then you've got a problem with your zipfile being acceptable to Python's zip file support and Django can do nothing about that -- again the right place to look for guidance on that would by a Python forum, not a Django one.

on delete cascade - best way to do override this behaviour?
Dear community, On some of our models we'd like to override Django's default "on delete cascade". (Customers that use our modified version of the Django-admin have proven to pay no attention at all to the messages that warn them for the deletion of multiple objects. It seems that a solution on the software side is more appropriate here than trying to educate our clients.) I've found that this subject has come up every now and then on this list, but it's unclear to me what's our best option. Via an old "restrict delete"-patch (http://code.djangoproject.com/ ticket/1007) through ticket 2288 I've found an interesting patch that sends out "all_objects_to_be_deleted in the pre_delete signal (http:// code.djangoproject.com/ticket/6108). A solution through signals seems very interesting to me, but there's no activity on this ticket since August last year. An other interesting option is a patch that allows to override the cascading behaviour by using an attribute on foreignkeys that can be set to "SET_NULL" or "RESTRICT" (http://code.djangoproject.com/ticket/ 7539). For this ticket there hasn't been much activity since last year either. I currently don't know what my best options are... Any input would be greatly appreciated.

Hi I am new to django and have just started to play. I have a working (small) app but wanted to turn on the admin console for the project. I edited the settings.py to include the admin module and now get the following errors NameError at /admin/ name 'admin' is not defined Request Method: GET Request URL: http://127.0.0.1:8000/admin/ Exception Type: NameError Exception Value: name 'admin' is not defined although I first saw the error using django 1.0.2, I can re-create it using 0.96. I have come to the conclusion that I am doing something wrong but can anyone tell me what? the relevant part of my settings.py looks like; INSTALLED_APPS = ( 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.sites', 'django.contrib.admin', ) and URLS looks like # Uncomment the next line to enable the admin: (r'^admin/(.*)', admin.site.root), ) i have removed evrything else from the project and app and still get the errror, at the top of the urls.py it makes no difference whether I have the line admin.autodiscover() or not as I still get the error Regards K --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

That is to say on .96 Django doesn't handle things as unicode. I'm not entirely sure what that entailed, but it occured for a reason so I wouldn't expect that to work.

Quick edit, I meant to ask if it could be a problem with the '.mo' files being created incorrectly...the '.po' files that contain the unicode translations are UTF-8. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

A quick question about slug fields
I believe these days a statment like this has been depreciated:
post_slug = models.SlugField(prepopulate_from=('post_title',))
I had a look through the docs but couldn't find the answer.
How can you now specify which field the slug is created from?
thanks,
Andrew

Re: Exception in Django's Exception Handling
I'll see if I can extract some small subset and post the details.
In the meantime, more info: the problem only occurs when an error is
encountered during a call in which the server will return a
HttpResponse('', mimetype='text/xml; charset=utf-8') object in
response to some AJAX request; things apparently work when the server
will return a render_to_response, which shows a page in the browser.
Before I switched to Django, and just used webapp (a simplified
version of Django in Google App Engine), the first type of problem
would dump the stack trace to the console. Now, the trace does not go
to the console, and it is here that the exception within the exception
is thrown.
Could this be a setting or path issue?

Question about media in outside forms
Hello,
I have been working on some forms which has some ajax behaivour, and I use
some css and javascripts. This can be used inside a form with {{ form.media
}}, which outputs the html tags necessary to import all the javascript and
css to get all the fields working, and without duplicates if the field
appears more than one time in the page.
But when I use the {{ form.media }} more than once (imagine a for is
generated for each element of a list and using includes or template tags) I
don't know how to get just one tag for each media.
Or when I need this behaivour to happen outside a form (with a template
tag), don't know if this is possible. I mean, the declaration of the media
and this is automatically included just when needed.
thanks,
Robert Ramírez Vique

Bizarre sqlite3 / apache2 behaviour
Hello, I installed yesterday Django 1.0.2 (current downloadable version) on a new Ubuntu 8.10 machine with python 2.5.2. I wrote a toy application and it works and shows fine with both the built-in development server and Apache 2 (2.2.9). The database is sqlite3, it came with python (btw, how do I get the sqlite3 version from python/the Linux command line?). Anyways, yesterday everything was working fine, including the admin application served by Apache. Today I only worked on templates, restarting apache frequently (I know about setting MaxRequestsPerChild 1 but anyways) but after a while I went to the admin application (served by apache) and I got an error: "OperationalError: attempt to write a readonly database", which is strange since it was working before and I haven't made today any changes to file or directory permissions or fiddled with the settings file. I looked up this error and I only see tips regarding permissions problems, bad path in the setting file or perhaps a sqlite version issue. I think none of that applies to me (since it was working yesterday) but I double-checked just in case. I tried different things for troubleshooting, including dropping the data with "manage.py sqlclear" and renaming the db file and re- creating it with "manage.py reset" and "manage.py syncdb" (I suspected perhaps the file was corrupted), but nothing I tried worked. I also checked the server (it wasn't rebooted recently etc). Here's a twist: if I start the development server and I log in, then the admin app in apache works fine (!), I can edit & save records etc. As soon as I log out of the development server, then apache gives me the readonly error. I'm ruling out client-side issues (cookies etc) since I tried with different browsers and computers, deleting session and cookies etc. Any ideas?

So far as I know, though, it doesn't provide it, rather you have to include it as part of your app. Which is a bit of a pain since Django as shipped contains more than 1,000 files and a GAE app is limited to no more than 1,000 files. This page: http://code.google.com/appengine/articles/django10_zipimport.html under "Archiving Django 1.0" provides some details on bits of the django tree you can omit from your django.zip file (e.g. translations you won't need) so that you can keep within GAE limits and still use Django 1.0.

signals in 1.0 problem: nesh django utils & django 1.0
Hello, I've recently been porting many projects to 1.0, but have hit a snag with the current one. I'm looking at an old project that uses nesh's django utils (mainly just the thumbnail image field model), and have been slowly porting the project (and by extension nesh's code) to 1.0. Now i have read the documentation on signals, as well as the porting to 1.0 guide's signals section, but because i have not really used signals in my projects, i'm a little unsure what exactly is being called for by this error, and thought someone here may be of some help. The original code looked like: def contribute_to_class(self, cls, name): super(ImageWithThumbnailField, self).contribute_to_class(cls, name) dispatcher.connect(_delete, signals.post_delete, sender=cls) dispatcher.connect(self._save, signals.pre_save, sender=cls) My poor attempt at porting: def contribute_to_class(self, cls, name): super(ImageWithThumbnailField, self).contribute_to_class(cls, name) signals.post_delete.connect(_delete, sender=cls) signals.pre_save.connect(self._save, sender=cls) and the resultant error: line 45, in contribute_to_class signals.post_delete.connect(_delete, sender=cls) File "/usr/lib/python2.4/site-packages/django/dispatch/ dispatcher.py", line 84, in connect assert argspec[2] is not None, \ AssertionError: Signal receivers must accept keyword arguments (**kwargs). now my understanding of the syntax is that _delete and self._save would be keyword arguments, but apparently i am incorrect.

checkboxInput values
If i use the multiple Checkbox Input, It results in list of the items
which were selected.
My question is can you do the same thing for a single checkbox?
As an old ASP guy I'd do this:
I'm trying to do this in django by the following:
#...snip forms.py
el1_Choices = (
('EN', 'ENGLISH'),
)
el1=forms.ChoiceField (required=False, choices=el1_Choices,
widget=forms.CheckboxInput(attrs={'class':'multibox'}) )
The resulting HTML is:
As you can see there is no value. It is returning the following
error:
Select a valid choice. That choice is not one of the available
choices.
Even though I've got the form field setup to required=False.
What is the proper way to assign a value to a single checkbox? Am I
just stuck with boolean and true/false? That seems like a lot of
extra work on the back end.

Subclass conflict with admin widgets
I have implemented this solution successfully with a standard model,
but when I try to use it on one which is subclassed I get an error
because it is trying to validate the model before it knows about the
subclass. I can work around this by defining an Admin class for each
of the subclasses, but it seems to me this should work?
Model.py
class Directory(models.Model):
name = models.CharField(max_length=60)
pic1 = models.ImageField(upload_to='pics', blank=True,
null=True)
class Business(Directory):
cat = models.ForeignKey(Subcategory)
Admin.py

class DirectoryAdminForm(forms.ModelForm):
pic1 = forms.ImageField(widget=AdminImageWidget())
class Meta:
model = Directory
class DirectoryAdmin(admin.ModelAdmin):
form = DirectoryAdminForm

('Contact', {'fields':

The best way to do this would be to make a templatetag that took multiple
form.media instances, added them together(which can be done with media
instances) and then output the response.

writing a urlpattern for a form submission
I'm sure this will come across as basic to many django users but it
has got me stuck so any helpful pointers would be appreciated. I've
scoured the docs and come up empty. Upfront apologies done now,
here's what I got:
Using django forms, i create a form which results in a submission
string like this:
http://127.0.0.1:8000/shiftcalendar/?year=2010&group=1&submit=Get+calendar
So in my urls.py I set up a urlpattern like this:
urlpatterns = patterns('local1042.shiftcalendar.views',
(r'^$', 'index'),
(r'^(?P\w+)/(?P\w+)$', 'showcal'),)
I thought that that would do it, and I've tried every variation you
could think of, but I'm missing something. I know I should use POST
but for debugging I've been using GET. The index page works just
fine. I just can't get it to call the showcal function.
Any thoughts would be appreciated.
Thanks. Kevin

Hi,
I've narrowed down the issue a bit. First, it's using revision 7901,
that is before newforms-admin.
The problem is in the 'change_stage' view:
def change_stage(request, app_label, model_name, object_id):
...
try:
manipulator = model.ChangeManipulator(object_id)
except model.DoesNotExist:
raise Http404('%s object with primary key %r does not exist' %
(model_name, escape(object_id)))
...
When retrieving the manipulator it raises a 'DoesNotExist' exception:
str: Traceback (most recent call last):
File "", line 1, in
File "C:\Djangos\catalyst\django\db\models\manipulators.py", line
260, in __init__
self.original_object = self.manager.get(pk=obj_key)
File "C:\Djangos\catalyst\django\db\models\manager.py", line 82, in
get
return self.get_query_set().get(*args, **kwargs)
File "C:\Djangos\catalyst\django\db\models\query.py", line 294, in
get
% self.model._meta.object_name)
DoesNotExist: Entry matching query does not exist.
But I only get that with those two Entry items (id=51,52). Why don't I
get it for the other items (id < 51)?
I'm really lost here. There must be some kind of corruption in the
data meaning it cannot find those particular items, but what could it
be? Again, those 2 blog entries work fine when displayed in the
frontend.
Do you think it could be a bug in that particular revision of Django
I'm using?
Any help would be appreciated.
Julien

I don't know what manager old forms admin used, but do you have a custom
manager that blocks access to some objects.

Re: How to detect inactivity session time out?
Any one with a clue on How do I detect time out in my app and give user a page that they have been timed out due to inactivity.

URL patterns don't match GET variables - ie anything after the ?. You
just need to match on /shiftcalendar/, and everything else will be
passed as keys in the request.GET dictionary.

You've made a really good point which helped me track this down.

The error message tells you what is going on. Your form definition has
model=Directory in its Meta class, so it only contains fields from the
Directory model. If you want it to contain the fields from the
subclassed Business model, you'll need to change that Meta
declaration.

FormSet with non input-element data possible?
Hi --
I'm creating a FormSet and want to include some data in the form output
that is not an html input element.
Some of the data I pass to the FormSet, which gets passed to the form, I
just want to display, I don't want to put it into an HTML input
element. I want it to be available in the template. Here is what I
tried, which doesn't work:
class SectionForm(forms.Form):
section_id = forms.IntegerField(label='Section ID:', required=False,
widget=forms.HiddenInput())
section_title = forms.CharField(label='Title', required=True)
section_text = forms.CharField(label='', widget=forms.Textarea,
required=True)
def __init__(self, data=None, auto_id='id_%s', prefix=None,
initial=None, empty_permitted=False):
super (SectionForm, self).__init__(data, auto_id, prefix,
initial, empty_permitted)
# This is what I want to do, more or less, but it won't work
(TypeError: unscriptable object)
#self.s3_audio_file = initial['s3_audio_file']
In the template, I want to display s3_audio_file, but I don't need or
want it to be editable. It's for information only. Just text, or
html-formatted text.
{{ form.s3_audio_file }}
Is there some way to have the form contain arbitrary data that I pass to
it with the "initial" dictionary?
Perhaps, I have to create a faux Widget and Custom field? That seems
like a long way around for something that should be simple.
Thanks in advance for any help.
Best,
Liam
Also, I was unsure about what to do with empty_permitted -- I got an
error before I added it to the super() call.

Re: Subclass conflict with admin widgets
Yes I see that, it's just if I don't put the custom form in it works
fine:
class DirectoryAdmin(admin.ModelAdmin):
fieldsets = [
(None, {'fields': ['cat','name','is_live']}),<
CAT FIELD STILL HERE AN OK
('Contact', {'fields':
['phone','mobile','fax','email','web','address']}),
('Details', {'fields':
['description','pic1','pic2','pic3','pic4']}),
]
admin.site.register(Business,DirectoryAdmin)
It suggest to me there is something in the admin code which normally
allows for this 'error' to pass. It's not a big deal, I just wondered
if it was somthing django should allow for and the design of the two
examples is inherantly the same.

Forms, fields and widgets
Hello, I'm fairly new Django user, but have some background experience with other frameworks. Sorry if this topic was discussed before, but I was not able to find any mention of it. My question is related to architectural decisions of the forms, fields and widgets. At the moment in Django, all "incoming" data is processed by the widget and clean by the field. Data flow: raw data -> widget -> field -> form. However, reverse process is different: data -> form -> widget data. As you can see, field does not play and role in reverse data conversion. Let's examine simple task. ModelForm calls model_to_dict() to initialize form fields with initial data. In case of models data is their id's. But what if one will want to develop widget that requires more than just a model id? For example: str(model) and model.id at the same time? There are not so many options how it can be done right now: or derive from ModelForm and override it's data gathering behavior (rewrite model_to_dict()) or run extra query in the widget itself (which is not optimal). Possible naive solution: if it would be possible to make field work in _both_ directions, it would be awesome. If field will know that it works with models (like ModelForm related fields), it will be responsible for cleaning data to the widget-appropriate format. It is my two cents. I don't know if somebody already tried to make it work this way of there were some reasons not to do this way... I don't know.

using the ImageField with the API
Hey everyone,
I've got an interesting problem concerning file uploads.
I'm building an online auction and my `Lot` links to a thin
`LotImage` so that I can store multiple images of the lots:
class Lot(models.Model):
...
lot_number = models.PositiveIntegerField("Lot number")
Class LotImage(models.Model)
...
lot = models.ForeignKey(Lot, related_name="images")
main_image = models.ImageField(upload_to=get_main_image_path)
you can see I've written a callable for the `upload_to` parameter
because I want to store the images in a particular place:
def get_thumbnail_path(instance, filename):
return os.path.join(
LotImage.BASE_PATH,
instance.lot.catalogue.__unicode__(),
filename
)
This is all good and works a treat in the admin UI, but how can I keep
this `upload_to` functionality when working with the API by hand?
Django's Documentation on the subject talks about the `File` class
(http://docs.djangoproject.com/en/dev/topics/files/#the-file-object)
which works fine when you explicitly create LotImages:
f = open('/tmp/hello.world', 'w')
myfile = File(f)
f.close()
LotImage.create(
lot_id = 1,
main_image = myfile
)
But by doing so, I loose the `upload_to` functionality. How can I keep
it without physically moving the file to the right place, then
creating a File object and attaching to a new LotImage?
I basically want to create exactly what the admin UI does with
uploaded files.
Can anyone help?
Thanks,
RM

YUI Image Uploader - OK on Firefox/Mac but not elsewhere
Have been trying to get a RTE plugin working that will allow upload of
images. The YUI verion is almost there but will not play well with
browsers.
The plugin from here
http://allmybrain.com/2008/11/06/example-yui-image-upload-with-yui-260/
I modified to get Javascript to make an asynchronous call to this
function in the view:
def uploadimage(request):
try:
upload_full_path = settings.CONTENT_IMAGES
upload = request.FILES['image']
dest = open(os.path.join(upload_full_path, upload.name), 'wb+')
for chunk in upload.chunks():
dest.write(chunk)
dest.close()
result='{status:"UPLOADED",image_url:"%s%s"}' %
(settings.CONTENT_IMAGES_URL, upload.name)
return_data = HttpResponse(result,mimetype='Content-Type: text/
html')
except Exception, e:
return_data = HttpResponse("Error in uploading image")
return_data.flush()
return return_data
The plugin was written for turbon gears/php and there is a tg example
here:
http://allmybrain.com/2007/10/22/yui-image-uploader-example-with-turbogears/
Firefox/Mac works perfectly. Safari downloads the image instead. No
version on PC appears to do anything, (but only have Mac for local
testing.)
Have tried every possible permutation of the content-type, Content-
Type and text/html definitely is the way to go. Various threads on
python refer to the need to open the file for reading as rb to make
sure windows knows it is binary, but not sure how to do that as the
response data is already in memory.
In desperation I have also tried to implement image upload in TinyMCE
- can't get FileBrowser working on PC. and FCKeditor no modifiable
image upload that I could find. So I am back with YUI and hoping
someone can suggest something to try

It _could_ be many things. However, unless you give us details, we
can't give you details. So far, you haven't even told us the
exceptions you are seeing. In the absence of details, we would only be
guessing, and given that none of us have seen this problem before, it
wouldn't be a particularly educated guess.
