What's happened is that you have indented the final line too much. It
should line up with the main function content - ie on the same level
as the 'else' above it, it shouldn't actually come under that else.
That means that if the form is a post, but doesn't validate, the flow
falls from if form.is_valid() straight down to that return - and so
the form that was instantiated by passing in request.POST is passed
back to the template, and rendered along with its errors. This is why
you don't need that commented-out else block.

The template is evaluated when first rendered, so the if statement no longer exists by the time the javascript executes. The way to do this is to output the content regardless, but use javascript to hide it (set the 'display' style to 'none'), then more javascript to unhide it when the box is ticked. -- DR. -- You received this message because you are subscribed to the Google Groups "Django users" group.

return number instead of string in admin

I'm glad we've worked out that Weave is the culprit, but nobody has answered the question of whether this is an indicator of a problem with Django itself. What is weave passing as a header (and under what conditions) that is causing a problem? Is there a need to improve Django's error handling to protect against this case?

Unindent the 'return render_to_response(...' lines, so that they are
executed when you have an invalid form. The form will be re-rendered,
except this time the form instance will be bound, and have appropriate
error messages in it.
eg:
if request.method == 'POST':
form = ...
if form.is_valid():
...
else:
form = ...
return render_to_response(...)

Re: Admin Model Validation on ManyToMany Field
Hi,
Just a guess: have you actually selected a user and a folder when
submitting the form? I think only valid field are present on the
cleaned_data dict, and your users and folder fields are not optional
(blank=True, null=True).

Redefine True and False for Boolean and/or NullBoolean Fields?
As I understand, in Django/Python, True is 1 and False=0. And when connected to the database, we use a TinyInt for that variable and assign it to a NullBooleanField. Problem is that some people use their PC's with a Microsoft Access based front end to the database (MySQL). The forms use check-boxes, and when checked, which is supposed be "true", Access puts -1 into the data base. Django doesn't recognize that value as True. I can't change the Access forms or system and don't tell me to stop using Access. We don't have unlimited resources to fix all the problems in the world! I'm wondering if there is some way to tell Django in the data model to let a model variable return True when <>0 (instead of when=1) , and False when 0? This seems the cleanest easiest way; but I can't see how to make this possible? Is it? Or is there another approach ? -- You received this message because you are subscribed to the Google Groups "Django users" group. To post to this group, send email to django-us...@googlegroups.com.

Re: Admin Model Validation on ManyToMany Field
Thank you for your reply.
Yes I have selected a user and folder.
I believe ManyToMany fields are always optional (hence many to many).
So my users and company fields are optional, but my folder field
isn't.
When I add a new Application in the Admin I do specify a folder and
users (if I don't I would at least get a 'Required field' error for
the folder field).
I've tested the method above (clean function) with another model that
has a manytomany field, and it does exactly the same thing, even when
I really do fill in the data. In fact, if I delibirately throw an
error and look in the debug info I can see the ManyToMany field data
being present in the POST data, just like I can when I do the same
thing with the above models.
Btw, I just noticed a typo in my Folder model description above,
that's not the issue as it's correct in my original model.

google blogger & ooyala video integration (apps)
Hi all, I have been working on a number of projects here at u-dox.com, we're a very heavy django shop and have been mindful to try and keep as much of the code generic as possible. A few things which I have written that might be useful to others are two fairly standalone apps - one for syncing and using google blogger content via its RSS feeds for any profile and another to integrate with the Ooyala video hosting platform. Both projects are available at github for anyone interested. The ooyala project can be used without django itself. Both are continuing works but they are at a point I feel I can share them. Blogger: http://github.com/jaymzcd/django-blogger Ooyala: http://github.com/jaymzcd/django-ooyala More info on both: http://jaymz.eu/2010/07/integrating-ooyala-in-django-or-in-general/ http://jaymz.eu/2010/06/google-blogger-to-django-integration/ Cheers, jaymz -- You received this message because you are subscribed to the Google Groups "Django users" group.

Managing static content / basically handling images best practices
I want to use ImageField for users to upload static content and I need a little advice from a some django pros on how to do this in a dev enviornment. I notice the disclaimer that django dev server should not used to serve static content, or it shouldn't be. So... What's the best practice for this then? Right now, I love the simplicity of the django dev webserver, should i switch the devserver to nginx? Does that have the ability to know when i make a change to a python file without a server restart necessary? Is there anything else I should know.

Re: Admin Model Validation on ManyToMany Field
Sorry, I can't reproduce your error with django 1.2.
I copied your models (just removed the intermediaty "Permission"
because I don't know your User model) into a new app and I have 2
scenarios Adding an Application in the admin:
a) if I select a User and Folder, the validation runs just fine
b) if I do not select an User, then the "clean" method is still
accessed, but since 'users' is not present in the cleaned_data dict it
throws an exception - which is the scenario you give, hence my
original guess :)

Dynamic Form Widget [django admin]
Hi guys, This might be best explained by example... for the following model: class Setting(models.Model): data_type = models.CharField() value = models.TextField() I want Django's admin to display a different form widget for the "value" field depending on the input of "data_type". For example: if "data_type" was "date", then the value field would use a date widget instead of the TextField's default widget. My predicament is that ModelAdmin is defined as a class, and not instances. So I can't pass it a custom form since instances (i.e. "data_type" value) are needed to decide what field the form should have... Any help would be greatly appreciated! thanks, Jon -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Managing static content / basically handling images best practices
I typically add a config to apache to ignore my media folder and not handle it with python so that requests to /media/.* all go straight to the webserver and don't go via django. I typically have something like this sitting in my conf's: SetHandler None Options -Indexes I'd not bother doing that for the dev environment though unless you've got your server setup already and its not much hassle. jaymz On Jul 14, 3:33 pm, reduxdj wrote: > I want to use ImageField for users to upload static content and I need > a little advice from a some django pros on how to do this in a dev > enviornment.

Re: Admin Model Validation on ManyToMany Field
Hi Heleen,
I think this is because your running the users through an intermediate
model. That changes the way you need to work with the M2M data. You
should be working on the Permission model/objects instead. If you
check out the M2M docs for models via an intermediate:
http://docs.djangoproject.com/en/dev/topics/db/models/#extra-fields-on-many-to-many-relationships
You'll see the example is pretty much what you have only with Group
instead of Application.
"The only way to create this type of relationship is to create
instances of the intermediate model. Unlike normal many-to-many
fields, you can't use add, create, or assignment (i.e.,
beatles.members = [...]) to create relationships:"

Re: Django Install - Won't Import?
Sounds like you're quite new to all this. If I was you I'd install setuptools for windows, it'll make adding packages a lot easier for you. http://thinkhole.org/wp/2007/02/01/howto-install-setuptools-in-windows/ The "setup.py install" command, you should have "python" before that so it actually executes. You can of course always just extract the django source code and drop it in your python packages also. If you execute "python" at the command line and try "import django" it should work.

Re: Managing static content / basically handling images best practices
Not sure if I understood the question, but here goes: Are you using the devserver on production? If you are, stop! It's perfectly fine to serve the static media via the dev server in a *DEV* environment. Here's some information: http://docs.djangoproject.com/en/dev/howto/static-files/#limiting-use-to-debug-true You will however encounter problems since your users won't upload their content to your DEV env, they will upload it to the production environment. You could either use something like rsync to sync the folders to your harddrive from the server. Another approach is to use something like this: http://github.com/sunlightlabs/django-mediasync nginx is great for serving static media but might add some complexity to your server setup, apache+mod_wsgi is the recommended choice by the documentation, and works really well for sites that dsn't receive huge amount of traffic. You would just specify a directory to use for static content in your apache config and make mod_wsgi handle everything else. The django and mod_wsgi docs have great articles on this. Good luck with your server setup.

Re: Valid objects are returning an http 404 response
Sorry to be so slow in responding. We were able to turn debugging on... and no one saw a 404 error with debugging on. Of course, debugging took a toll on the database server so we were not able to just leave it on. We have audited our code and we were able to clean up quite a bit but we do see this problem still, but with less frequency. If we get to the bottom of it, I can post what we did to fix it.

Adding object via m2m relationship in save() method -problem
Hello!
I have a problem which i can't solve on my own. I have already
searched the web, but without success.
I have the following two models which are related with a many to many
relationship using Django 1.1 with Postgres on Unix:
FIELD_TYPES = ( (u'int',u'int'),
(u'string',u'string'),
)
class MediaAttribute(models.Model):
attribute = models.CharField(max_length=100)
value = models.CharField(max_length=100)
type = models.CharField(max_length=30, choices=FIELD_TYPES,
default='string')
def __str__(self):
return self.attribute + "=" + self.value
class MediaItem(models.Model): # inspired by the ImageModel of
photologue
id = models.AutoField(primary_key=True)
file = models.FileField(upload_to='uploads/archive/')
view_count = models.PositiveIntegerField(default=0,
editable=False)
created_at = models.DateField(auto_now=True)
updated_at = models.DateField(auto_now=True)
attributes = models.ManyToManyField(MediaAttribute,blank=True)
def __str__(self):
return self.file.name
def
create_or_update_attribute(self,the_attribute,the_value,the_type='string'):
'''
Updates or adds an attribute of a mediaItem.
'''
related_attribute =
self.attributes.filter(attribute=the_attribute,value=the_value)
if related_attribute:
return
related_attribute =
self.attributes.filter(attribute=the_attribute)
if related_attribute.count() is not 0:
for attribute in related_attribute:
self.attributes.remove(attribute)
MediaAttribute_object, created =
MediaAttribute.objects.get_or_create(attribute=the_attribute,value=the_value,type=the_type)
self.attributes.add(MediaAttribute_object)
self.low_level_save()
return MediaAttribute_object
def save(self, *args, **kwargs):
super(MediaItem, self).save(*args, **kwargs)
current_photgrapher = 'photographer name'
self.create_or_update_attribute('photographer',
current_photgrapher)
I want to associate keywords with a mediaitem, but in a loose and
dynamic way since many photos share the same attributes as
photographer for example. i want to save the photographer's name at
the beginning after the mediaItem object has been created.
The strange thing is, that when i call the function
create_or_update_attribute from within save(). There is no error
message and also a new MediaAttribute is properly created, but it's
not connected with the MediaAttribute in the database.
The function "create_or_update_attribute" works correct when called
outside the save function (e.g. from a view). Then a connection
between the MediaItem and the MediaAttribute is made correctly. Like
so:
m,c = MediaItem.objects.get_or_create(pk=1)
m.create_or_update_attribute('photographer','test')
(this works correct. it creates a new MediaAttribue and makes also a
connection to the MediaAttribue in the Database.)
Can anybody help me? I would appreciate any advice!
Thank you very much,
Frederic

Re: problem models.py code
I'm not exactly sure what you want. So, I'm only assuming that you might be
trying to do something like:
jono = models.AutoField(unique=True)
instead of what you're currently using.
Thanks,

Re: problem models.py code
Just set primary_key=True on your field:
jono = models.PositiveIntegerField(primary_key=True)
See the django documentation for details:

Overriding ModelForm field's value in the admin changeview
Does anyone know where in the admin changeview the fields in a ModelForm is populated with the information from the database? I was hoping to override one of the fields in a subclassed ModelForm.__init__(), e.g.: self.base_fields[field_name].initial = 'foo' But the population appears to be happening farther down the chain, as 'foo' is overwritten with the value from the database.

Re: Anyone want to take over maintaining Instant Django?
Thanks for the replies. To be clear, I'm not looking for hosting, I'm looking for someone to take it completely off my hands. This means doing whatever you want with it, but I would hope it would at least mean keeping it up to date. This only takes and hour or two whenever a new version of Django is released, but I no longer have any interest in doing it. @Andy - The "build" script is a windows '.bat' file. Basically, you put all the components that comprise Instant Django into a folder, run the '.bat' file, and in builds the Instant Django download. This got a little harder to do after the Python dev's broke the MSI installer. Prior to Python 2.6 you could install Python from the command line into a self-contained temporary directory, without touching the underlying host system. This is no longer possible, and I couldn't convince anyone that mattered that it was a problem.

Re: Look up model instance by id
Try: directory.models.Entity.objects.get(pk=id) Which does pretty much the same thing as: directory.models.Entity.objects.filter(id__exact = id)[0] (note id__exact rather than id__equals) On Jul 14, 3:18 pm, Jonathan Hayward wrote: > How do I look up a model instance by id (its primary key)?

Django 1.2.1, Postgres 8.3 - Cast (text to int) Issue
Hi, Wonder if someone can help. I have a piece of code (filtched from elsewhere) that retrieves the comments for a particular Entry (blog post): Comment.objects.filter(content_type=ContentType.objects.get_for_model(Entry), object_pk__in=Entry.objects.filter(title=self.title)) Problem is, that with Postgres 8.3 (and seemingly Django 1.2.1), this command fails: " django.db.utils.DatabaseError: operator does not exist: text = integer HINT: No operator matches the given name and argument type(s). You might need to add explicit type casts. " Having searched around in various forms this appears to be a sort of known problem (see http://code.djangoproject.com/ticket/10015). The issue is that object_py in Comments is a "text" field, whereas the id field in Entry is an int - hence a cast is required. I can make the actual SQL work in Postgres 8.3 by altering the start of the WHERE to be: "WHERE (cast(django_comments.object_pk as int) IN (SELECT" i.e. adding the 'cast'. So, my question is: what's the best way to go about this in Django 1.2.1 with Postgres 8.3? (8.3.8 to be exact). Any thoughts/ recommendations most welcome. FYI - this is for use with Djapian.

Suggestions? Would it make sense to open a bug?

Re: Look up model instance by id
One slight difference: If you need to deal with the object not being found, you get a different error using get as opposed to using filter and then pulling the first element out of the collection. Here's an example, with Location being the model class: try: Location.objects.filter(pk=id)[0] except IndexError: print 'Not found!' # ...handle error here... try: Location.objects.get(pk=id) except Location.DoesNotExist: print 'Not found!' # ...handle error here...

Re: Managing static content / basically handling images best practices
This is kind of an aside to your question, but I think you'll find it useful... There are two types of static media that you'll want to have served separately to your dynamic django application: * project static media * uploaded media I like to keep these two separate. My preferred way to do this is to use STATIC_ROOT/STATIC_URL for the project static media, retaining the default MEDIA_* settings for uploaded media only. When using the built-in development server, it is fine to use it to serve your static media. When you shift to a full webservice stack, for your static media you'll make your web service bypass the django wsgi app or use a seperate web service altogether. One final catch is when you need to develop a stand-alone apps which needs to have its own media files. A nice solution to serving all the your static media easily in the dev server, and collating all your app's static media to a single location is http://bitbucket.org/jezdez/django-staticfiles/src On Jul 15, 2:33 am, reduxdj wrote: > I want to use ImageField for users to upload static content and I need > a little advice from a some django pros on how to do this in a dev > enviornment.

altering the sessions class
So, I am using request.sessions in one of my views functions but I want to add a few more fields to the Session class so it will be customized for my project. When I tried to go to the Session class (in django.contrib.sessions.models) and simply adding in an extra field, and then adding it to my admin (I put the django_session table to the admin), I got an error saying that attribute didnt exist. My question is, where do I need to make changes so I can add my own fields to the Session class. I also tried having another class inherit the Session class and add fields to the inherited class but the problem I had with that is I couldnt use request.inheritedClass where inheritedClass is the class that inherited the Sessions class. The error I received when I tried doing request.inheritedClass in one of my views function was this: 'WSGIRequest' object has no attribute 'inheritedClass'. To sum it up, can anyone tell me some way to customize the Session class to my liking? Thanks, Tony -- You received this message because you are subscribed to the Google Groups "Django users" group.

Now, the docs say to pass in the Class name, and the stack seems to be

What am I doing wrong?

Re: How to handle Jaywalking - parsing a comma-delimited value in field and do lookups (1,4,5,6...)
One idea that springs to mind is to add a property method to your
model that returns that self.group field as a list. With that list you
could add another property that returned all the actual group items.
Then write a custom admin view for add/change/view of that model which
works with the group instead. That way you can leave the data intact
but provide a management interface on top. Likewise you can in your
front end use your new propertys to work with the groups related to
that user. Whatever you do will probably involve a layer of work on
top.
So in your model I'd add something like:
@property
def group_list(self):
return self.group.split(',')
@property
def real_groups(self):
return Group.objects.all().filter(pk__in=self.group_list)
For writing a custom admin view this is to do with something a little
different but it's pretty comprehensive in terms of writing a
completely custom admin view:

ordering a model on multiple fields?
is there a way to have a model class sorted on multiple fields? in the meta class of my models I set the ordering, but django uses only the first field for ordering; a second field is just ignored. (I am aware that if a users starts to sort using table headers in the admin interface only one field will be used. It would just be great to have the initial ordering on 2 fields.) kind regards, henk-jan ebbers -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: www.djangoproject.com
Hi, I had the exact same problem, and I had _not_ installed Weave. The offending config entry in my case was: "chrome://global/locale/intl.properties" and it was at the bottom of the accepted languages list. This is on Firefox 3.6.6 I can reproduce the problem anytime by visiting about:config and changing "intl.accept_languages" to en-nz,en,de,chrome://global/locale/intl.properties *.djangoproject.com will stop responding, (all?) other websites seem fine.

Re: Redefine True and False for Boolean and/or NullBoolean Fields?
Oh ... by the way, we aren't using Access as a front end to Django. There is nothing (far as I know) in Django to front-end to! This app has been successfully making us money for more than 20 years. The data side moved to MySQL a long time ago (can't remember when) to enhance performance and security, but the relatively sophisticated Access side remained in place and continued to evolve. Still see no viable replacement on the horizon for Access for the front end for use by people. There are a number of tools that have suficient capability to replace it but all would cost a fortune to make it happen. Instead, we're using Python/Django as a basis now for enhanced reporting/number-crunching and future automation (which sends us in the direction of having so many people having to use the Access app). Had we had Python and Django in the late 1980's we'd probably be there now.
