Button with save and custom action in Admin

[Rob]

In Django 1.4 I am working on a small mailing app, and in the admin change 
page I would like to add a button called "send mailing". When the user 
presses the button the model should be saved first, en then redirected to a 
custom page to view and confirm the mailing before send.

I saw lots of snippets, custom actions etc. etc. but I cannot get it 
working. 

I have add a custom change_form.html in /templates/admin/myapp and 
succesfully added a button. But how do I "tell" Django to do the two 
actions?

When I add name="_save" to the button the model is saved after pressing the 
custom button, but now I need a redirect to a custom page using the currect 
model.

Make sure you have files 500.html and 404.html in your templates folder. If
not create them. Or use django 1.5

No - not if you run that code on every (applicable) request. Ignore
the cost of reading it from disk - if you read a file from disk
repeatedly, even the worst OS should start to cache that file - the
actual cost is repeatedly re-parsing the XML document.

What you want to do is cache the resulting object, the parsed XML
document. An easy way to do this is by using a global:

__xsd_cache = None
def get_xsd():
  global __xsd_cache
  if __xsd_cache is None:
__xsd_cache = parse_xsd()
  return __xsd_cache

def parse_xsd():
  ...

The only problem with caching is that eventually, what is cached is no
longer correct. You will need to think about how and when you will/can
invalidate the cache.

Cheers

Tom

Re: Loading XSD file into memory ONCE

[Ludwig Kraatz]

Hi Dwayne,

I would suggest just use the django cache api:

https://docs.djangoproject.com/en/dev/topics/cache/#the-low-level-cache-api

Memcache is able to store 1mb Value.

https://docs.djangoproject.com/en/dev/topics/cache/#memcached

If you don't have / want a memcache instance, you can use local memory 
caching. ( providing a local memory cache for every process running your 
system. )

https://docs.djangoproject.com/en/dev/topics/cache/#local-memory-caching

Then easily do 

current_xsd = cache.get(xsd_id)

if not current_xsd:
   current_xsd =*load xsd from disk?*
   cache.set(xsd_id, current_xsd)


best regards

ludwig

Re: How to make django-registration use Chinese as username?

[Tomas Neme]

I *think* it should work OK, data-wise. Try changing the
login/registration forms so chinese characters pass the verification
process. You can start by trying with a simple CharField with no
verification and see if it works.

Django Celery FIFO ORDER

[psychok7]

So I have this 2 applications connected with a REST API (json messages). 
One written in Django and the other in Php. I have an exact database 
replica on both sides (using mysql).

When i press "submit" on one of them, i want that data to be saved on the 
current app database, and start a cron job with celery/redis to update the 
remote database for the other app using rest.

*My question is, how do i attribute the same worker to my tasks in order to 
keep a FIFO order?*

I need my data to be consistent and FIFO is really important.

Django-MongoDb deployment at production servert

Hi,

I am developing a website using Django and MongoDb 
(http://django-mongodb.org/). I have read lots of forums and posts but 
still not able to figure it out what is the best way or default way to 
deploy Django project on web. So I have couple of questions related to 
this, it will be great if some one can guide me.

> Do I need a dedicated servers to implement Django with MongoDb if yes 
then what is the min/max requirement for them. What all controls and 
permissions I need for those servers. 
> What is the default way to deploy it (Django project with MongoDb), what 
is the best way to deploy it.

Datastructure using django.

[Subhodip Biswas]

Hi all,

I am trying to implement a tree structure using django. There are two
packages I am looking at mptt and treebeard. Treebeard seems easy.

I have however two questions:

1. With mptt I found that if you have moved one child to another parent
both db and instance is updated but you need to reload or reregister every
time you call such action.Is there a better way of doing this?

2. If my child have more than one parent, the structure does not remain a
tree anymore. It becomes a graph i guess, How do you handle such situation.

3. How do I add treebeard or mptt into django admin. If I have one field
name and I register it in admin.py. I get error regarding depth,path,
numchild and name should be present. How do I handle this situation.

Apologies for asking so many questions.

Another way to do this is with a cron task to runs a management command.
That still takes a separate task, however, if that costs money on heroku
(I'm unfamiliar with heroku).  You could spawn a thread at some point,
making sure that there is just one, and let it sleep for a fixed time (or
set the equivalent alarm signal), waking up to see if it has any work to do
(this can be hard to get right, and hard to debug).

You could use a separate queue for these tasks, and set up a single

Re: background task without celery

[Nikolas Stevenson-Molnar]

You can configure a celery worker on the the same server you run
everything else on. Then you can still use celery (which is useful if
you ever want to scale to a separate worker machine down the road.

Implementing a monitoring system with django.

[Marc Aymerich]

Hi,
I'm considering to implement a simple monitorization system that
basically gathers some data from a set of nodes (<1000 nodes). The
gathered data should be stored in order to let users perform some
queries and maybe also generate some graphs.

I'm looking for advice in what components are best suited for each of
the following parts:

1) Storage: maybe something nonsql like MongoDB? or perhaps RRD?
2) Data gathering: celery periodic tasks?
3) Graphs: rrd? or some java script framework for graphing?

thanks for your comments!!

Re: Django Celery FIFO ORDER

[Nikolas Stevenson-Molnar]

Use the manage.py command described here:
http://pypi.python.org/pypi/django-celery to start the worker (I use
supervisord to manage the process). If you only start the worker on a
single machine, then you'll only have one worker. This can be the same
machine that runs your webserver.

I investigated alternatives to Celery, and came up with a handful of worthy 
alternatives. See my blog posts at 
http://seeknuance.com/2012/08/09/my-requirements-for-replacing-celery/ and 
http://seeknuance.com/2012/08/14/alternatives-to-using-celery/, they might help 
your search.

I suspect you're on a Mac and your jpglib is not compiled properly. If you
are on Mac make sure you look into that.

Django ajax HTTP 500 when trying to access request.GET

[Loai Ghoraba]

Hi all

I am trying to write a simple ajax that tries to know whether the username 
already exist before registering.
Whenever I try to access the request.GET in my view function, a HTTP 500 
error is raised, if the view function doesn't access it and only use hard 
coded values-for test- it works.

Any help ?

My code is :
jquery:

function checkUserNameUnique()
{
$.ajax({url:"/ajax/",
data:{username:$("input.username").val()},
success: function(result){
$("span#usernameMessage").text(result);
}
}
);
}
view:
def ajax(request):
username=request.GET["username"]
msg=""
try:
user=User.objects.get(username=username)
msg="username is okay"
except User.DoesNotExist:
msg="username already exists"
return HttpResponse(msg);

Possible Bug with GenericRelation and values_list

[Skylar Saveland]

I may have found a bug. I made a test case here:

https://github.com/skyl/django/commit/556df1c46146c2fc9c4022d838fa23f652f0ea8d

The final assertion fails. Is this a bug or do I misunderstand how this 
should work?

Thanks

Project path

[Lachlan Musicman]

Hola,

I've got a split settings set up for my prod/dev sites, and in all the
hints I've  seen over the years, I've most appreciated the line at the
top of the settings file that goes like this (there are variations to
the theme):

BASE_DIR = os.path.dirname(os.path.abspath(__file__))

But almost all of the docs that I grab this info from are pre
Django1.4, and I believe it was 1.4 where the structure changed
slightly - settings are now in

path/proj/proj/settings.py
path/proj/app1
path/proj/app2

I would like BASE_DIR to be path/proj/ so I can use it in
STATICFILES_DIRS for instance, but it's coming out as path/proj/proj/

I am thinking about:

SETTINGS_DIR = os.path.dirname(os.path.abspath(__file__))
BASE_DIR = os.path.join(SETTINGS_DIR, '..')

But it seems a bit convoluted or horrible.

Does anyone have a better solution they could share?

cheers
L.

Re: IOError, Permission Denied using Amazon s3 w/ django-storage?

[easypie]

This is on Ubuntu. I am using Mezzanine framework built on top of Django. 
'pip install mezzanine' helps grab all the dependencies like Pillow (PIL). 
I'm not sure if this is what's causing the problem but thank you. I'll take 
a look at this.
