Re: Django Powered Tabblo to be acquired by HP

[bedros]

nice work; I've always been impressed by Django; and Tabblo website
gives a more convincing reason to use Django.

But, I'm still not sure on javascript/ajax library to use with
Django... so my question which ajax kit did you use with Tabblo.

Thanks,

I don't think you're doing anything wrong - I've had similar comments

loaddata against postgresql doesn't update primary key's sequence 'last_value' ?

[Jon Ballard]

Hello everybody, I'm new.  Django is the bomb.. my app is coming
together quickly.

Now to my issue..

I dumped my database to json and tried to ingest it back in.  Seemed
to work fine at first -- everything was there -- but it turns out no
new records can be added because the sequence field 'last_value' for
all the auto primary keys was left at 1, despite many records being
added to the respective tables.  Now I tend to think this might
actually be an issue with Psycopg, but why would it manifest itself
only when using loaddata?

My setup:
Django 0.96
Ubuntu 6.10 (Edgy)
PostgreSQL 8.1.8-0ubuntu6.10
Psycopg 1.1.21-7

This is the error when trying to add a new record:
IntegrityError at /admin/spots/spot/add/
ERROR: duplicate key violates unique constraint "spots_spot_pkey"
INSERT INTO "spots_spot"

Anyone have any ideas?  Am I doing something wrong perhaps?  Thanks
for any help.

I'll continue to research of course..

Ordered list of objects?

[Nathan R. Yergler]

I'm working on an app for a client, and one of the requirements is
that they be able to re-order objects in the admin interface.  I know
exactly how I'd do with with an object database, but the ideas I've
come up with for doing it with Django all involve using some tracking
field, and then updating that to contain the relative order of
objects.

So... am I missing something obvious here that will let me do with
with a minimal amount of pain?

Thanks,

Nathan

The "url" template tag is a wrapper around
django.core.urlresovers.reverse(). So you can call reverse directly and
pass in the URL pattern's name rather than the view name if you like.

The equivalent of the above example in a Python function would be:

reverse('full-archive', args=(1945,))

Using url in a view

[Chris Moffitt]

Is there a way to access a named url from within a view?

For example,

Using this as a reference-
http://www.djangoproject.com/documentation/url_dispatch/

say, I have this url:
url(r'/archive/(\d{4})/$', archive, name="full-archive")

and access it like this in a template:
{% url full-archive 1945 %}

Is there a way i could access it in a view?

def archive(request):
Some code to access which named url here

Basically, I'd like to access the value "full-archive" while in the
archive view.

Does this make sense?  If so, is this possible?

Thanks,
Chris

Django Job at WeFi

[Pablos]

Hopefully it is copacetic to post jobs to this list, I'm stoked to be
creating Django jobs!

About Me

I'm Pablos, and I'm looking for coders for my team.  You will talk to
me about this job, not a recruiter.  If this doesn't sound like the
job for you, please introduce me to the most stellar coders you've
ever worked with.  Email me directly:  [EMAIL PROTECTED]

Oh, you're right.

But, all of your other code is also in that if block.  So if the user is
authenticated, the view doesn't return anything.

Looks like you just have an indentation problem.  Remember, Python code is
whitespace-sensitive.

I thought we fixed this a bit before 0.96 was released. Are you using

Re: newforms and form_from_instance

[Luciano Adamiak]

Gary,

after some testing I came to this solution:

I created my own form_for_instance function like this:

def form_for_instance(instance):
f = forms.models.form_for_instance(instance=instance, form=MyCustomForm)

f.base_fields['email'].initial=instance.email
...
f.base_fields['senha'].initial=instance.senha

return f()

So... if I need a form for an instance it uses the
forms.models.form_for_instance using MyCustomForm, then I create an instance
of this form and set the initials in the fields.

I know it's not smart, but it works..

I can't see anything immediately wrong with your model - however, the
error you are reporting sounds like a known problem with the
manipulators and edit_inline. I can't remember the ticket number of
the top of my head, but I do know that problems with edit_inline and
manipulators is one of the many reasons that we are introducing
newforms.

GenericRelations exist for this kind of relationship. GenericRelations
aren't completely stable or documented, and they aren't fully
supported in the Admin, but they do work reasonably well, and there
are some examples of their use at:

I am not sure what you mean
I have a HttpResponseRedirect if the user is not authenticated.
This error happens with an authenticated user.
If the user is not authenticated he/she gets redirected to the login
page and that works fine.
See:
if not request.user.is_authenticated():
return HttpResponseRedirect('/account/login/?next=%s' %
request.path)

The way your view is written, if the user is not authenticated, no HttpResponse
is returned (since no return statement is executed).  You probably want to just
raise Http404 in that case.

Re: request object out of a view (I need to access session['data'])

[Karen Tracey]

I'll try to elaborate what James said.  (Did you consult the documentation
links he pointed to?  They detail how you get the request object accessible
in your templates, and thus your custom template tag.)

In order to get access to the request object in your custom template tag,
you must make some code changes elsewhere.  First you must include '
django.core.context_processors.request' in your TEMPLATE_CONTEXT_PROCESSORS
in settings.py.  Second, in the view that initially handles the request, you
must pass a RequestContext (instead of a plain old Context) to your call to
render_to_response.  Then, your template context will contain a variable
'request' that you can pass on to your custom template tag.  You can do this
either by passing it in as another argument ({% menu position request %}
instead of just {% menu position %}) or you could investigate using the
takes_context=True parameter on your register.inclusion_tag.

Basically you have to go all the way back to the view that initially handles
the request in order make sure that the request object continues to be
accessible in your templates and in the custom template tag you have
created.

Hope this helps,
Karen

Re: request object out of a view (I need to access session['data'])

[Grupo Django]

I don't know if I didn't understand you or if I you didn't don't
understand me :-)
Not sure abou what you are saying, I think I can't use it to make the
template tag work.
The template tag doesn't use a view to render the content, so it
doesn't get the request object as a parameter.
This is the code of the template tag:
--
register = template.Library()
def menu(position):

data = request.session["stored_data"]
...
return {'output': output,}

register.inclusion_tag('menu/menu.html')(bloque_menu)
--

So I need to read into data the data that is stored in the session.
But the request object is not accessible.
Sorry, I didn't understand what you wrote very good.
Thank you.

Look into using RequestContext[1] in your views (generic views all use
it automatically), and enabling the "request" context processor[2].
This will make the variable "request" -- containing the HttpRequest
object -- available in template contexts, so in your tag's 'render'
method you could access it by doing something like:

def render(self, context);
request = template.resolve_variable('request', context)
...do stuff with the request...

request object out of a view (I need to access session['data'])

[Grupo Django]

Hi, I need to know how can I access data stored in the session out of
a view.
I have created a custom template tag which has to check a variable
stored in the request.session. It's strictly necessary to store the
data in a session variable at this moment.
Inside the custom template tag, I don't get the request object since
it's not a view.
I have no idea about how to retrieve the data.

And a secondary question related to this. If I wanted to retrieve a
value by GET within the template tag. Is it possible to access it?

Thank you very much.

Do you have all sites under the same VirtualHost, or do you have a
different VirtualHost container for each? You aren't really clear on
this as your description mentions different sites but your Apache
configuration only shows a single one being setup.

BTW, if under separate VirtualHost containers, do not use the
PythonInterpreter directive as you are to set them all to use 'py' as
the sub interpreter as then they will all overlap. When using
mod_python, the default is to give each VirtualHost container a
separate Python sub interpreter and thus they would be separate, you
appear to perhaps be overriding that.

Re: Vote only once/Remembering votes

[[EMAIL PROTECTED]]

I pulled the karma bit of contrib.comments out and made it a more
generic app, so I can use it anywhere. I have it store who voted as
user (as I suspect you would). And at that point all you have to do is
something like:

if KarmaScore.objects.filter(user = request.user):
return HttpResponse("You already voted!", mimetype="text/
html")

Note that in my case I'm actually returning the HttpResponse with
AJAX, so I don't care about building a page. I just want a string in
my response.

Re: MySQLdb version

[joey101]

I did this all, but it still doens't work :(

When running ./dispatch.fcgi directly it looks as though the problem
is all cleared up, but even after killing fcgi 'till it's dead it
still brings up a 500 error on my site.

Does this sound like it's still related or is it some other problem?
If it is another problem any one have ideas on finding out what it is?

Thanks!

Web Sites keep pointing against each other

[Keith Mallory]

I have a Ubuntu Server with 4-5 Django web sites hosted on mod_python.

Everything works fine, expect that the web sites keeps on pointing against
each other. That Site A points to Site B and B to C and so on.

This is how I have set up my httpd.conf

NameVirtualHost *


ServerName example.com
SetHandler python-program
PythonHandler django.core.handlers.modpython
SetEnv DJANGO_SETTINGS_MODULE exp.settings
   Alias /admin_media "/var/www/exp/admin_media"
PythonPath "['/var/www/exp/projects/'] + sys.path"
PythonDebug On
PythonInterpreter py

SetHandler None





When I retstart the Apache Server, every site works perfectly, but then it
all fails to point to the right domain. This has created a very embrassing
situation. Has anyone experienced this, and what is the remedy?

Re: Curious error with Session Variables

[Ramdas S]

browsing through the user groups, I see that the issue is a clash between
Django and PHP4/5. I cannot turn them off, since some sites on our server
still use PHP. Is there any solution where we can ensure that Django does
not clash with PHP and live peacefully.

I am eager to know

Curious error with Session Variables

[Ramdas S]

Since last few days I am getting this error on Django web sites hosted.
Obviously it is clashing with something.

When I work on admin interface to add or delete content, I get logged off
and it takes some time for me to login again.

I get the following messages

Please enter a correct username and password. Note that both fields are
case-sensitive.

If I keep on trying then the message changes to

Looks like your browser isn't configured to accept cookies. Please enable
cookies, reload this page, and try again.


Later if I persist

I get this error

-

SuspiciousOperation at /admin/ User may have tampered with session
cookie. Request
Method: POST  Request URL: http://developeriq.com/admin/  Exception Type:
SuspiciousOperation  Exception Value: User may have tampered with session
cookie.  Exception Location:
/usr/lib/python2.4/site-packages/django/contrib/admin/views/decorators.py
in _decode_post_data, line 40





I am using the latest development version Mod_Python, Apache and Ubuntu
Linux

What can be the reason



Thanks


Ramdas S

The Server is a dedicated server, and it also runs PHP, MySQl and some PHP
and Python software.

models.TABULAR Question ...

   Element 1 [delete]
   Element 2 [delete]
   Element 3 [delete]

   add new Element   new Container

Is there a switch for this? Currently I can only get the num_in_admin

Your suggested code implies that it be dynamic though. The
models.FileField() line will only ever be executed one time. You're
passing it the value get_current_user(), but that value only ever gets
passed that one time.

If it were "dynamic", then get_current_user() would get called
everytime the FileField is accessed, which is what you wanted, but
that's not the case. Hence Malcolm's comment :)

Thanks for the help.  I didn't call it dynamic, though.  What are you
referring to?

I'll look through the fields.py file and see what I can do.  I'm
pretty new to Django and even Python, so I'm guessing I won't have
much luck ;)

edit_inline causing problems with multiple relations

[mh]

I have two models that (simplified) look like this;

class List(models.Model):
 name =models.CharField(maxlength=128)
 class Admin:
  pass

class Entry(models.Model):
 name = models.CharField(maxlength=128, core=True)
 list = models.ForeignKey(List, edit_inline=models.TABULAR)
 to = models.ForeignKey(List, null=True, blank=True,
related_name='to')

This doesn't seem to be working ('bool' object is not callable); any
suggestions on how I could fix it?

While at it I might as well ask a second question;
Each entry can reference either another list, or something else. Is
there any way to construct a foreign key from two fields (and have it
work in the admin if possible)? My current solution is to have
multiple foreign keys of which one is active and the others are null -
works but feels somewhat ugly ;).

Re: Generic views. Really generic

[[EMAIL PROTECTED]]

Thanks, Malcolm. That's basically what I was thinking. To clarify,
though, I was saying a custom view for this would be quite simple -
almost trivial - and I'm most assuredly *not* a programmer. I was only
leaning toward a generic view because I trust them more than I do my
own code.

Anyway, since the items know which category they're in, I'll just pass
the category and item slugs to the view and query for the item that
matches.

Thanks!

Re: Copy table Design many, many times

[Robert]

Ned, True,

Thanks both for quick reply.  Actually did try exec at first.. .
character  When it went wrong at first, I doubted myself and thought I
meant eval from js instead hence that post.  I went back to it and
realized how to include the nest "pass" just underneath it using the
escape

---clearly a semi newbie with python

As for the table situation.. actually I do understand databases a bit
better than python and realize that normally one would make a single
table or rather just a few tables instead of copying the design of one
many times.
This is an oddball application, however.. nothing that is going to
serve a web site, but something I am just doing to verify something
else.  Call it an off-label use of a db.

Thanks again..

Robert

I'm not an expert in this area yet, but I suspect you are waiting on
some new functionality that has only just been committed on the
newforms-admin branch. If you have a look at
http://code.djangoproject.com/changeset/4836 you'll see that Joseph
Kocherhans committed the subforms-within-forms stuff that is needed for
behaviour like edit_inline.

On django-developers recently, there was a thread
(http://groups.google.com/group/django-developers/browse_frm/thread/8b6094bd8811c140/#
 ) that talked about exactly this.

So you could (a) experiment with the newforms-admin branch, since it
tracks trunk fairly closely, (b) pull out the relevant bits from [4836]
and apply them to your local copy, or (c) wait a little longer until
newforms-admin is merged with trunk. The above thread indicates that
Adrian is eager to move forwards on this. So it looks hopeful.

Sorry if none of these are a perfect solution for you. It's work in
progress at the moment.

Regards,
Malcolm

Re: Access to m2m relation in model's save()?

Your understanding is basically correct and at the moment you can't get
to this information directly inside the saving process. Here's a
slightly long explanation of why it's not possible and what we might do
about it.

The problem is that a bit of a chicken-and-egg conflict: many-to-many
relations are saved in an intermediate that saves the ids for each pair
of objects. So if object A is related to B1 and B2 via m2m, we save the
[id(A), id(B1)] and [id(A), id(B2)] as two rows in the intermediate
table (by id(A), I mean A's primary key value).

In order to save the pair id(A), id(B1), we need to know both those
values. We only know id(A) after object A has been saved, in the case
where it has an auto-generated primary key value and is being saved for
the first time (i.e. created). So the A.save() method is invoked before
the m2m saving is done. After all the objects have been saved, the
AddManipulator object saves the intermediate relations.

We don't talk about AddManipulator and ChangeManipulator objects much in
Django, because they are an under-the-covers feature. We do talk about
manipulators in general a bit in the (old)forms framework and
AddManipulator and ChangeManipulator are just automatically generated
versions of those.

Now, in the medium- to long-term, we are, of course, moving away from
oldforms to newforms. Part of the reason for this change is that
manipulators turned out to be a bit of a brain-twister in their
complexity.

Your particular problem, though is one that hasn't yet become easy to
solve. I think we will end up adding a new signal that is emitted when
the m2m relations have been saved, maybe passing the list of saved
objects to the signal handler or something. This hasn't really been
discussed much in detail yet, but it is a missing piece of functionality
that we will solve at some point.

Regards,
Malcolm

Access to m2m relation in model's save()?

I'm trying to get the values from many-to-many relation in the model's
save() method, but the list of related objects is always empty. After
the save(), the list has expectd content, but not until the save()
finishes. Is this normal behaviour and I should look elsewhere to

Not sure if you noticed this note in the docs, but your application can
only support translations that are "known" to Django's core as well. So,
out of the box you are restricted to the list under django/conf/locale/.
See
http://www.djangoproject.com/documentation/i18n/#how-to-create-language-files .

The good news is that it's easy enough to add an extra locale to the
core so that your application can support that locale. You will need to
modify your Django source for this. At the moment there isn't a way
around that. I might get around to fixing this one day (or somebody else
might, which would be great, but at the moment, I seem to be the
de-facto i18n maintainer), but it's relatively low priority at the
moment -- partly because we'd like to encourage translations of Django's
core.

To add an extra locale to Django, do the following (I'll use "af" as the
example):

(1) In the django/ directory, run bin/make-messages.py -l af.
This will create django/conf/locale/af/LC_MESSAGES/django.po and
djangojs.po in the same directory.

(2) In the django/ directory, run bin/compile-messages.py -l af
to generate the corresponding .mo files.

(3) Add an entry for 'af' either in
django/conf/global_settings.py (in the LANGUAGES list) or in
your own settings file.

This creates an empty translation file for the Django core. It doesn't
add any value to your translations, but it does mean that your
project/application translation files will be used for your app-specific
strings. At this point, you should be good to go by settings
LANGUAGE_CODE and so forth.

Note that the reference to "dummy gettext()" in the docs is just saying
that you should avoid using the real (imported) gettext() function in
that file. Just copy what global_settings.py does if you want that. We
mark all the language names as translatable in global_settings.py, for
example.

Regards,
Malcolm

If i remember correctly, .add() takes an object that it needs
association to, so you'll have to do (where condition expresses which
group you want to add the user to):

group  = Group.objects.get(condition)
new_user.groups.add(group)

I'm not sure why it doesn't raise errors there though, if .add() only
accepts a related object.

Re: M2M relationships via an intermediary table .. how do i get to the data in my template?

[oliver]

Hi, yes i was approaching it very wrong, but figured it out.
Here is a little test which i got to work with the help of some IRC
django people! (Thanks).

I didnt know that django would also send all the related items from
the intermediate table to the template. Very nice!
I guess I should do some filtering thou as this could be a lot of
data..

Using my "news", "imagegroup", "images" setup, this is how i get to
the "images" data from the news object.

Yes News as a name would be better but than admin made Newss out of
it ;), I forgot that you can define the plural some where in the
model.

This gets the 1st result:
{{ new.imagegroup.all.0.image.caption }}

{% if new.imagegroup.all.0 %}
This has images
{% else %}
This has NO images
{% endif %}

This gets all results: 
{% for newsitem in new.imagegroup.all %}

{{ newsitem.createdate }}

{{ newsitem.position }}

{{ newsitem.image.caption }}

{{ newsitem.image.get_imagefile_url }}


{% endfor %}
