I also have a similar problem in a project right now and have thought of 2
possible solutions. First is to use a FloatField or a DecimalField (o). Do
not reset it on every FK change. If the user wants to insert something
between records a & b, assign it a o value which is average of a.o and b.o.
If you are not expecting too many such insertions, it should work fine.

The other option is to store the ordering explicitly in the Foreign Key
model using a JSONField. This means that you will have to move all the work
involving ordering in the python layer which may or may not be suitable for
your case.

Currently I am going with option 2 for my case.

Abhaya

Re: Django 1.4: TypeError: get_db_prep_value() got an unexpected keyword argument 'connection'

[Russell Keith-Magee]

Hi,

What you've hit here is the end of the deprecation cycle for code that doesn't 
support multiple databases.

In Django 1.2, we introduced multiple database support; in order to support 
this, the prototype for get_db_preb_lookup() and get_db_prep_value() was 
changed.

For backwards compatibility, we added a shim that would transparently 'fix' 
these methods if they hadn't already been fixed by the developer.

In Django 1.2, the usage of these shims raised a PendingDeprecationWarning. In 
Django 1.3, they raised a DeprecationWarning.

Under Django 1.4, the shim code was been removed -- so any code that wasn't 
updated will now raise errors like the one you describe.

All the core Django fields should have been updated to use the new signature, 
so if you're seeing errors, it's probably because of a custom field that you're 
using that needs to be updated. As far as I can make out, Django's default 
ImageField shouldn't have this problem (it doesn't even have db_prep_* methods, 
because there's nothing database specific about the storage of FileFields).

If you can reproduce this on a project that only uses Django's built-in field 
types, then this is a bug in Django that needs to be addressed.

Yours

loader.select_template breaks template name

[gnesher]

Hi,

I'm receiving some odd results while playing with select_template
(Django 1.4)

I'm calling the following code in my view:
loader.select_template('test.html')

Which results in the following error:

TemplateDoesNotExist at /test
t, e, s, ., h, m, l

Can't really figure out what I'm doing wrong as this should be rather
straightforward.

Thanks

No it's not that (the new location is the same as the old). But I
figured it out - the django python package is apparently a
subdirectory of the git repository. I did this:

mv django django.git
ln -s django.git/django django

Re: Upgrading django on a mac

I'm guessing that your $PATH is configured to look for django in it's old

Upgrading django on a mac

[Larry Martell]

I'm on a mac, running Mac OS X Version 10.5.8 (Leopard). I was running
django -r 13034 that I got from SVN. I am trying to upgrade to 1.4
from git. After I upgrade, python can no longer find django. Here's
what I did:

$ cd /usr/local/lib/python2.6/dist-packages
$ sudo mv django/ django-13034
$ sudo git clone https://github.com/django/django.git django
$ python
Python 2.6.7 (r267:88850, Jan 11 2012, 06:42:34)

>>> import django
Traceback (most recent call last):

If I switch back:

$ sudo mv django django1.4
$ sudo mv django-13034/ django

It again finds it:

Reloading a project without restarting Python

[Tobia Conforto]

Hi all

I'm developing a portlet bridge in Jython, to enable developing J2EE
portlets in Django, and I need to include a reload-on-code-change
feature, to aid in development.

Unfortunately, the way django.utils.autoreload works, by triggering a
complete restart of the Jython interpreter, has huge memory and thread
leaks in Jython.  It would appear that there is no clean way to unload
a
Jython interpreter from the JVM once it's been started.  (For backing
of
this assertion, see my latest post on the jython-users list.)

Therefore I'd like to know if there is a way to reload a Django
project
from within Python, without restarting the interpreter itself.

For normal development it would be enough to reload the project's own
models, views, urls, admin, form, middleware and such classes.  Some
of
the settings could be kept, if it made the reloading simpler, such as
filesystem paths, database connections, installed apps and middleware.

Any changes to the standard library, Django, and in general any code
that is not part of the current project's module could be ignored. If
a developer needs to reload that, he can very well restart everything!

Does anybody have any advice on how to do this?

-Tobia

Re: It's magic the view does not exist for django but it worked 5 secondes before and it still exist

the problem is solved.

Just saving the view file under vim solved it.

It must have been an encoding problems with the file.

But it was strange because it reads some part of the file.

Re: It's magic the view does not exist for django but it worked 5 secondes before and it still exist

[Bussiere]

 No views in invitation works.


  I was working on live with the test server runnning.

 (i've tried to restart it more than one time after i get this error).

 And by magic all the views in invitation don't works, they are not 
 found.

 Maybe a reinstallation of django ?

 Have you any suggestion ?

 No views in invitation works.


  I was working on live with the test server runnning.

 (i've tried to restart it more than one time after i get this error).

 And by magic all the views in invitation don't works, they are not 
 found.

 Maybe a reinstallation of django ?

 Have you any suggestion ?

Re: superclass SingleObjectMixin

[Dave]

Thanks Daniel, appreciate the super fast response! I did your
suggestion and it works like a charm. It's better than putting the
method in each class. Was just hoping there is a way I could override
get_object in the singeobjectmixin everywhere vs. adding another mixin
for each CBV. Perhaps i'm just being too lazy

Thanks again!

Dave

I'm not quite sure what you're trying to do here, especially in your use of 
"superclass" rather than the more normal "subclass". In any case, you can't 
simply subclass something but call your class the same name as the parent 
class and just expect all references to the superclass to be magically 
replaced by your class.

The thing I guess you're missing is that SingleObjectMixin is, well, a 
mixin. So you can just mix it in to your view class:

class ItemDetailView(MySingleObjectMixin, DetailView): 

and according to Python's rules of inheritance, it will find your 
get_object method in place of the original one.

superclass SingleObjectMixin

[Dave]

Hi, I need to manipulate my pk when using new class based views. In
order to DRY I think what's needed is to superclass SingleObjectMixin.

I have the following but it's not working. Greatly appreciate help/
suggestions!

In view.py have the below which does not work.

from django.views.generic.detail import SingleObjectMixin
class SingleObjectMixin(SingleObjectMixin):

def get_object(self, *args, **kwargs):
queryset = self.get_queryset()
pk = pid_to_oid(self.kwargs.get('pk'))
queryset = queryset.filter(pk=pk)
obj = queryset.get()
return obj

return super(SingleObjectMixin,self).get_object(self, *args,
**kwargs)

from django.views.generic import ListView, DetailView

but if I do the below it works(but prefer to not have to add this to
each CBV).

class ItemDetailView(DetailView):
model=Item

def get_object(self):
queryset = self.get_queryset()
pk = pid_to_oid(self.kwargs.get('pk'))
queryset = queryset.filter(pk=pk)
obj = queryset.get()
return obj

Thanks in advance for the help.

Dave

Re: It's magic the view does not exist for django but it worked 5 secondes before and it still exist

[Marcin Tustin]

So, you can import the function in the django shell? Have you considered
replacing the string-based import with a normal import?

I agree that if the data in the db was entered correctly in the first
place, then just ORDER BY on the FK and PK would be sufficient. However, if
the user needs to insert some data between sequence #3 and sequence #4,
then I have to muck with the primary key of the table, which sounds
dangerous.

Perhaps a better analogy would be to think of a linked list as my in memory
data model, and I want to translate that to a sql table(s). I found a
reference http://www.artfulsoftware.com/mysqlbook/sampler/mysqled1ch20.html,
that may solve my problem.

Apologies for not being clearer in my original post.

Field objects take 'connection' and 'prepared' kwargs in Django 1.4. It
sounds like you're using a custom field which was written before those
parameters existed, or perhaps you upgraded from a previous version and
didn't delete all the .pyc files.

If it's the latter, it's a good idea to completely delete your Django
directory from site-packages before re-installing. If it's the former, you
can add the kwargs with a default of None and pass the values to the
super() call.

Re: It's magic the view does not exist for django but it worked 5 secondes before and it still exist

[Marcin Tustin]

Reinstalling django will not help. Verify that the file is present and has
the correct permissions (likewise all superior directories, and also the
relevant __init__.py files. These files are essential.).

You may also like to run the django shell, and try to import that module.
If that does not work, examine the sys.path setting to ensure that
jackpoint is on the path.

Re: It's magic the view does not exist for django but it worked 5 secondes before and it still exist

[Bussiere]

i've made no deploiement at all ...

No views in invitation works.


I was working on live with the test server runnning.

(i've tried to restart it more than one time after i get this error).

And by magic all the views in invitation don't works, they are not found.

Maybe a reinstallation of django ?

Have you any suggestion ?

Re: It's magic the view does not exist for django but it worked 5 secondes before and it still exist

[Marcin Tustin]

Does  invitation/create_invitation work? If not, I suspect that you have
either some kind of configuration issue, or the file has gone missing from
your deployment/has wrong permissions set.

Django 1.4: TypeError: get_db_prep_value() got an unexpected keyword argument 'connection'

[xthepoet]

This was working fine for my Ubuntu 10.04LTE system with Django
1.3.1.  It seems broken now in 1.4.

In Django 1.4, I get this error  TypeError: get_db_prep_value() got an

This problem was also reported on the django-celery board:

But I've realized that for me, it's not a celery issue.

Re: Why using Generic Views?

[Phang Mulianto]

HI,

i understand why need to use generic views after i code some of my function
like showing list of data, and the view is the same and i end up copy paste
it , not type it (smarter huh?) , just change my db object and pass to my
template.

well , generic view is come in the rescue and we can produce faster result
with less code, just call the generic function  in the url.py files and
point to your template to render.

hope help..

Re: AttributeError at /admin/coltrane/entry/add/ 'Entry' object has no attribute 'pubdate'

[laurence Turpin]

Thank you  akaariai for replying to my post.
When I looked at the problem the next day I had a different problem.
I have since learnt that when you create a django project in eclipse you 
should not select the option for an src folder as it confuse django. I have
therefore decided to restart from scratch.

Re: Improving Site Performance

[Phang Mulianto]

Well.. i think the lazy query is on action.

The query executed to get the data from database to be use in your view, if
you said requestContext(..)

if you remove it, of course the data will not available in your
view/template.

To reduce the query executed everytime you call the page, try use query
caching..
one quick way without change code is use some cache like johnny-cache..it
will automaticly cache your query and unvalidate it if your data changes.

i used it to.. and try load your page more than once, you will see in the
debug toolbar, the query is reduced in the second and next load...that is
the cache in action..

hope help..

Templates and Models

[Sophia]

Hi all,


I have the following form( TextBox ) :



I wrote the following Model as an input for the TextBox, and when we write 
a subject in the text box and press Enter it should be shown in another box 
above the TextBox :

class Company(models.Model):
Subject = models.CharField(max_length=30)

def __unicode__(self):
return self.Subject


I don't know how to relate these two together, would you please give me a 
hint?

Thanks in advance.
Sophia

Re: Django 1.5 static files strangeness

[Mike Dewhirst]

My bad. Not a bug.

In my urls.py ...

if settings.DEBUG:

urlpatterns += patterns('',
(r'^media\/(?P.*)$',
'django.views.static.serve',
{'document_root': settings.STATIC_ROOT}),
)

from django.contrib.staticfiles.urls import staticfiles_urlpatterns

urlpatterns += staticfiles_urlpatterns()

... which is needed to find the static files and not wanted with Apache.

Sorry

Mike

The workaround is obviously to use DEBUG = True on the dev machine

Might be a bug
