RE: using a models fields

[Chris Matthews]

Hi Jay,

I am no Geo expert but if you use the CharField then you can specify N/E/S/W 
(North/East/South/West) or + and - to control latitude & longitude. With the 
DecimalField you can only use the + and -.

BTW, Marty Alchin's book Pro Django (Chapter 5 page 118), shows a nice example 
to validate user input for latitude & longitude. He actually use the 
DecimalField and extends it with a clean method, checking that latitude values 
to fall in -90 to 90 & longitude values to fall in -180 to 180.

Regards
Chris

You can try saving the data as 
latitude=models.DecimalField(max_digits=7,decimal_places=4).Same for the 
longitude field.Here the max_digits takes into account both decimal and 
non-decimal places.All the data can be given in string form as it will be 
automatically converted to proper format as specified in your models for 
storing in database. I guess you will be using some criteria to extract data 
from the database...so,code can look like

list_of_XYZ()=XYZ.objects.filter(criteria)
for i in list_of_XYZ:
i.latitude,i.longitude ,i.zoomlevel

Hello,

I got a couple of fields from a model I want to use

so the models.py looks like this

class XZY():

   latitude = models.CharField()
   longitude = models.CharField(.)
   zoomlevel = models.CharField()

I want to retrieve the data inside latitude, longitude and zoomlevel
to be able to create a static map for different locations, using google maps

How can I retrieve the fields data?

thanks

RE: Python Decorators

[Chris Matthews]

Hi cootetom,

For decorators you must have a look at the excellent articles/tutorials:
http://www.artima.com/weblogs/viewpost.jsp?thread=240808 
http://www.artima.com/weblogs/viewpost.jsp?thread=240845

It covers decorators with (what you want to do) and without parameters.

Subject: Python Decorators

Hi all, not exactly a django question but here goes... I'm trying to
implement a decorator with one positional argument and one keyword
argument. My wrapper function gets the positional argument just fine
but the keyword argument throws an error "NameError: name 'as_string'
is not defined."

Code is;

def widget(widget_switch, as_string=False):
def decorator(func):
def wrapper(*args, **kwargs):
# logic in here can access the value of 'widget_switch'
but 'as_string' is not defined?
return func(*args, **kwargs)
return wrapper
return decorator

So if I decorate a view function with "@widget('some_widget',
as_string=True)" then the wrapper function is unable to use
'as_string'. I thought this was how python closer worked?

Any ideas?

Restful interfaces help this situation.  When you get the uid through 
javascript, make an ajax post/get to the server and pass the uid to the 
function that way. If you need it before you render the page, there are python 
facebook modules you can use.

Dear All !

I am creating Django user login page via facebook.

I can login and get the facebook user's uid. I want to compare this

How should I do? Now I can not take the facebook uid to python

Yes, startproject is still a valid command for django-admin.py. Do you have
the environment variable DJANGO_SETTINGS_MODULE set to something? That would
cause the behavior you are seeing, per:

Including other fields in Admin interface

[Joseph Hunt]

Greetings,
I'm sure there is a simple solution to what I'm trying to do but 
unfortunately I wasn't able to find it in the documentation.
I have the following model (simplified version shown):

class Student(models.Model):
  student_id = models.IntegerField(primary_key=True, unique=True,
  db_index=True, max_length=9)
  first_name = models.CharField(max_length=50)
  last_name  = models.CharField(max_length=50)

  def __unicode__(self):
return u"%s %s" % (self.first_name, self.last_name)

class Course(models.Model):
  course_id = models.AutoField(primary_key=True, unique=True,
  db_index=True, max_length=4)
  title = models.CharField(max_length=50)
  dept = models.CharField(max_length=6)
  number = models.IntegerField(max_length=5)
  student_id = models.ManyToManyField(Student, blank=True)

  def __unicode__(self):
return u"%s %s" % (self.dept, self.number)

What I wanted was to be able to add students to multiple classes in the 
admin interface similar to the way that I can add students in the classes 
admin interface.

Thanks in advance for any help!

If you used django-ldap-groups you could create a security group of only

I thought to take the same line about eDirectory being off-line and not

how to have a comment hidden while moderated?

[mongoose]

hi

How do I setup the django comments so that when a comment is posted it
will not appear and be pending moderation( email sent to admin to
approve or reject comment )? As default it just posts and shows
straight away.
Do I need to use "class CommentModerator moderate_after" ?


thanks.

Stop changing things around so much, it makes any suggestions by people

Go watch:

It explains how to do things and where you can go wrong.

Re: wsgi configuration

[Mark]

Not sure if this will help, but worth a stab. Check this page:
http://code.google.com/p/modwsgi/wiki/IntegrationWithDjango I had a
similar error and it fixed it for me.

After it tells you how to set up the django.wsgi it says this may not
work if you used the Django server to set up your site. Django puts
some paths in it that Python doesn't yet have using WSGI. Your
situation is a little complicated as I am just getting into Django,
but I figured I'd share this document if it may help.

Good luck,

Mark

Jinja2 & Django 1.3 Integration - Example?

[deefr]

Hello-

I've been reading 
http://docs.djangoproject.com/en/dev/ref/templates/api/#using-an-alternative-template-language

and am interested in integrating Jinja2 with my Django 1.3 project.
The only useful example I have found is the following snippet:

http://djangosnippets.org/snippets/2063/

I get the following error for Line 16 in the above snippet.

'module' object has no attribute 'Template'


Can anyone tell me what I'm doing wrong, point me in the right
direction, or provide an up-to-date & working example similar to the
snippet above?

Thank you in advance.

To coin a phrase, it's not a bug - it's a feature.

form.errors is actually an instance of a custom class, ErrorDict, which is 
defined in django.forms.util. It subclasses dict, so it works exactly the 
same as a dictionary when you set and access its members - but it also 
defines a custom __unicode__ method, which is called automatically when you 
`print` it, which converts the contents to HTML. This is so you get a 
nicely-formatted output in your template.

form.errors is not a dictionary?

[Roy Smith]

I'm using django-1.3 .  I have a view with the following code:

def item_create(request):
if request.method == 'POST':
form = ItemForm(request.POST)
if form.is_valid():
url = form.cleaned_data['url']
item.save()
return HttpResponseRedirect('/')
else:
print form.errors

when I submit the form, I expected that form.errors would print out as
a dict, as documented in 
http://docs.djangoproject.com/en/1.3/ref/forms/api/#using-forms-to-validate-data.
Instead, I'm getting a hunk of HTML:

Re: wsgi configuration

[yongzhen zhang]

Hi, thanks for reply, i have tried this. Now in order to make it
clear, i move the iStore under home, like this: "/home/yongzhen/
iStore". django.wsgi is inside apache file and the apache file is
under iStore: "/home/yongzhen/iStore/django.wsgi". The content of
django.wsgi:
 import os, sys
wsgi_dir = os.path.abspath(os.path.dirname(__file__))
project_dir = os.path.dirname(wsgi_dir)
sys.path.append(project_dir)
project_settings = os.path.join(project_dir,'settings')
os.environ['DJANGO_SETTINGS_MODULE'] = 'iStore.settings'
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

and in /etc/apache2/sites-available, there is istore file, i have $
sudo a2ensite istore. the content of istore:
NameVirtualHost *:80

Re: QuerySet "disappearing"

[Matthew Riedel]

Nevermind- I *finally* figured it out.. It was this bit:
"for contact in contacts[startIndex:startIndex+100]:"

The contacts.count() in this case would steadily decrease as I changed
the status of the objects to no longer fit the queryset criteria. So
the startIndex value would get to the point where it would be more
than the total number of records (about halfway through)..

In other words, as my startIndex went up, the number of records went
down, and at half way, the startIndex was no longer a valid offset.

Since I realize this now, I'm just using the limit of 100, since it
the queryset automatically removes objects no longer matching the
query.. Seems more obvious now that I know what it's doing, but I
thought once I assigned a queryset to a variable, the data in the
query stayed, regardless of what changes I make to an object.. :\

Thanks,
Matt

QuerySet "disappearing"

[Matthew Riedel]

Ok, I'm having a bit of a weird issue with a medium-sized QuerySet
(~21k records). I have an app that syncs information from our LDAP
Directory and creates shared contacts in Google Apps for our domain.
Google puts a limit on 100 entries per batch, so I'm cycling through
these 21k records 100 at a time.

Here's the relevant code:

contacts = Contact.objects.filter(status__in=['up', 'cr', 'dl'])
contactsLog.info("Retrieved %s contacts." % contacts.count())
startIndex = 0
while startIndex <= contacts.count():
contactsLog.info("Sending records %s through %s of %s." %
(startIndex, startIndex+100, contacts.count()))
contactsFeed = gdata.contacts.data.ContactsFeed()
for contact in contacts[startIndex:startIndex+100]:
  <...do stuff...>

It all starts fine- I log out how many contacts are found, etc. and
it's getting the correct number (21k) and starts churning through them
100 at a time. However, when it gets to about 10,800 or so, the query
seems to stop working. I know this because I write the contents of
each batch out to a file. Around that mark, I start getting empty
batches. I don't get any errors or anything; the job continues but
just starts creating empty batches at that point.

The job finishes "successfully", but obviously it didn't. If I turn
around and run that job again, it happily picks up where it left off
and then does another 5-6000 records or so, then does the same thing
(the QuerySet appears to be empty, even though there should be records
left).. And again, if I restart it, it happily keeps going.

I've tried numerous ways to get this to work- I've tried using
Django's Pagination module, I've tried using the list() function
around the QuerySet call. Nothing seems to work.

My hunch is it might be hitting some cache limit, or apache memory
limit, but I'm unsure of how to figure that out. Especially since the
job runs to completion, it just stops getting records back.

I'm running Django 1.2.4, with Apache/2.2.17 (Unix) w/ mod_wsgi 3.3 on
Solaris 10 X64.

I'd be greatly appreciative if someone can point me in the right
direction. Let me know if there's output from any configuration files
you want to see that would be helpful.

Thanks in advance,
Matt

sounds like your going to have some fun ;) good luck, especially if
you can get rid of dealing with spreadsheets and automate it I'm sure
users will be happier(you at first;)

if You start a public git repo i'd like to read your progresses

Re: Django app for data management and visualization

[alessio c]

Hi Javier,

maybe we could have a talk, it sounds you need something similar to what I
need. Most of the reports needs a lot of ad hoc features, that is why it is
really difficult to find a proper level of abstraction. However, a robust
django framework could at least help to organize the work. Most of the
reports are run from data extracted from some IT syistem (SAP), this means
that the row data is usually following a model (which the people then mess
up in Excel). So, the approach model-view can be quite powerful.
Let me know. At the moment I only have spare scripts, but it would be nice
to share.

I feel your pain

what i'm currently doing is to use jqGrid as a frontend for tables.  i
wrote a small framework adaptor that lets me write a small class with
a Queryset, a few column description and optionally some extra data
transformations.  the superclasses take care of generating the JS
description and AJAX-handling views.

the advantage of jqGrid is that it makes very easy to handle record
selection, add/edit/delete/search operations, and sometimes in-cell
editing.  in sum, the users don't miss so much their excel sheets.

i plan to eventually share the python code; but it's still in heavy
flux, every new project demands significant modifications.

Re: Django app for data management and visualization

[alessio c]

Ciao,

yes I do. I need more basic stuff then that and I need tables. Think of this
as tentative to reduce Excel use (which is killing me).

I can use matplotlib or openflash if I want to go really fancy. However, now
I need to set up the framework. After that, I have a platform from which I
can run all my scripts.

Let's say I have a database with invoice data from different subsidiaries. I
want to be able to: 1) create different views (subsidiary level, macro
level, invoice level, first 10 invoice, first 10 customers, etc.); 2) upload
data from different formats (because people are lazy and it is impossible to
impose a single format); 3) allow some users to upload data (to avoid them
to send me excel files by email, this is a huge feature...); 4) allow some
other users (managers) to access and download online reports (tables and
graphs).

Theoretically, when I get this right I am hoping to start a project on git.
The main idea is to create a shared reporting tool.

Re: Apache2 with static file

[Steve]

I'm not sure what settings you have defined outside the 'VirtualHost'
section in your http.conf.

My guess is that you haven't set up the permissions to allow access to
the static media directory:


Order allow,deny
Allow from all


Also, I can't see your WSGIScriptAlias anywhere? Are you using
mod_wsgi with Apache?

Re: Static/media url in template

[Jon J]

N/M, I solved it. I found this little gem:

from django.template import RequestContext

[code...]
return render_to_response('base.html',locals(),
context_instance = RequestContext(request))

which gives me access to the URL from the templates. This should
definitely be in the documentation in the basic templating tutorial
because up until I've found this, everyone has been acting like
MEDIA_URL is accessible with no additional steps.

Re: Static/media url in template

[Ryan Osborn]

You need to have *django.core.context_processors.media* in your 
TEMPLATE_CONTEXT_PROCESSORS 
setting in order to use this template tag.

The same with STATIC_URL, you need to have *
django.core.context_processors.static* in order to use it.

Hope this helps,

Ryan

RE: [Suspected Spam] Django app for data management and visualization

[Sells, Fred]

There are guys in this group who are much more sophisticated meta
programmers than I.  But here's a very simple method:

It is easiest if each unique module has the same class name, such as
"class Controller:"

Then define and import all your plugins (does not allow uploading
plugin, but that's risky anyway).  You can get all the files in your
plugins dir and import them using the python function (forgot it's name,
don't use it) or just eval ('import %s' % filename)  crude but works for
older python

Create a dictionary of key:module's

Mymodule = ModuleDictionary[somekey]
Workingobject = Mymodule.Controller(**parms)

Subject: [Suspected Spam] Django app for data management and

Hello,

I am thinking about starting a Django app to manage data (I need it
for financial reporting).

What I am wondering about those days is a way to create an application
that:

1) Allows the privileged user to insert a "plug in" that adds a module
and its views.

2) Allows the user to add views and "scripts" to an existing model.

The way I think this is a model centric application with different
views and file uploaders. For me this would be a break out as we use
to run different reports from the same dataset (just changing the
grouping, filtering, formulas). I need file uploaders as the same
model can be populated from different files, organized in different
ways.

Do you have some aviced on best practices to achieve this? I don't
want the user to touch the main web site when adding modules and
views.

how to change form field in admin?

[galgal]

Is there any way to change type of 1 specific field? I want to change 1 
field from CharField to TextField. I know I can make a modelform and pass it 
to admin class, but is there any other way?
For example - can I somehow use formfield_for_dbfield?

Django app for data management and visualization

[alessio c]

Hello,

I am thinking about starting a Django app to manage data (I need it
for financial reporting).

What I am wondering about those days is a way to create an application
that:

1) Allows the privileged user to insert a "plug in" that adds a module
and its views.

2) Allows the user to add views and "scripts" to an existing model.

The way I think this is a model centric application with different
views and file uploaders. For me this would be a break out as we use
to run different reports from the same dataset (just changing the
grouping, filtering, formulas). I need file uploaders as the same
model can be populated from different files, organized in different
ways.

Do you have some aviced on best practices to achieve this? I don't
want the user to touch the main web site when adding modules and
views.

It seems like you're trying to mix up the development server (./manage
runserver) with Apache serving statics. I don't know why would you
want that.

If you want to serve statics from the development server, then you should read:
http://docs.djangoproject.com/en/dev/howto/static-files/


See you,
Andres

Just a minor disagreement but you can do the same in the shell/commandline 
(generation/editting). The gui is just 'prettier', that's the real differece, 
perception. 

Yeah it is much more general and glad to hear that. I'll post back when the

This shouldn't happen, definitly. Getting at the first item of a non-
empty queryset is something that should JustWork(tm), and it's very
unlikely that such a major bug could make it's way into a stable
release - FWIW, I've been using Django since the 0.96 days and I'd be
very surprised to get such a problem even on the trunk.

Making 100% sure your queryset is not empty when this error occurs is
no big deal. If you manage to reproduce this behaviour with a proven
non-empty queryset, then you can submit a bug report.

If you mean that adding the call to queryset.filter can result in an
empty queryset, then yes, obviously you can't hope to subscript it.

I posted some code about this. Also and FWIW, "./manage.py shell" let
you run any arbitrary code against your models so you can try out and
explore interactively. And there's of course the debugger.

Extending django-admin.py startproject/manage.py startapp: a good layout for reusable apps

[MrMuffin]

I`m writing a simple extension of django-admin.py/manage.py so I can
have a predefined set of configurations and use those when I create a
new project or reusable app. For instance, I use sqlite3 in the
initial stage of development so that should be set automatically. My
name doesn`t change that often, same for me email. Those things should
go into the settings.py by default. And when I create reusable apps I
don`t want to bother with setting hardcoded links in settings.py to my
template-folder in settings.py either.

So what I`m thinking of is an extension of manage.py, let`s call it
"lime" for now, an executable script, working something like this:

1. All my default values; name, email, django settings that doesn`t
change much are stored in a config file in my home directory like
~/.lime/config.ini
2. When I call "lime app blog" the result is:

* a folder with a package called blog, a complete reusable django app
( I use the standard django code to generate the app itself )
* a setup.py with my name, email, package info, basics requirements -
all ready for pypi uploading and distribution
* a test-project to test my reusable app, configured to use that app
and find the templates and static content automatically without adding
hardcoded paths to the settings.py of the test-project and an admin
inteface enabled by default
* a virtualenv for my test-project
* code revision files for files to ignore etc
* 

The goal is to quickly create a standardized, complete and distribute-
friendly layout for a reusable app and to cut down on the manual,
repetetive typing. I`m also planning to support different configs so
calling something like "lime app blog --config postgresql" will use a
config specifying the app to use a config called postgresql instead of
the default.

So what are your thoughts? And what is a good layout for a reusable
app? What else could be automated in django development?

My main motivation for this project came when I started working on a
plugin for the Editra editor for django management. I wanted to create
django reusable apps from inside the editor and I saw that a lot of
the initial work on a new app is very repetetive - first create
project, then create app, then edit settings.py, then urls.py to
enable admin, then edit views.py to enable admin etc. I want to have a
configurable standard layout for my apps created in very few steps,
from within Editra and outside the editor as well.

Thanks for your attention and hope to hear some of your ideas or
thoughts.

Regards,
Thomas
