The problem here actually lies with Python.

For some reason, Python 2.7 changed the reporting behavior of Warnings
so that DeprecationWarning is ignored by default [1]. So, because
you're developing in Python 2.7, you don't see the warnings by
default; in production, where you're using Python 2.5, you do.

Re: Issues with ManyToManyField

Try unique_together on employee and team in the TeamMember model -- it
will throw an error if you try to add a record with the same employee
and team as another.

Try a ManyToManyField, which essentially creates the article_devices
table but abstracts it away so you don't have to think about it.

defining model with list of foreign keys?

[Alex Hall]

Hello all,
I am trying to figure out the best way to represent a field in a
model. The model is an article, which is associated with multiple
devices (devices is another model). When adding a new article, an
admin is presented with a multiple select list of all the rows in the
devices table. All selections should then be stored in the article's
"devices" field. What should this "devices" field be, though? It has
to represent a bunch of primary keys in the devices table, which
sounds like a comma-separated list, but it also has to be of type
ForeignKey. Is there a way to do this, or am I better off just making
a model for article_devices, with pk article_id and a foreign key into
the devices table (so the article_devices table has a composite key of
[article_id, device_id])? I hope I explained that well enough. Thanks.

Issues with ManyToManyField

[Felipe Spychalski]

Hello,

I'm having an issue with my schema and the admin interface where I got
2 tables with a ManyToMany relationship: Employee and Team.
The problem is I'm able to add one Employee to the same Team twice.
Is there a way to prevent this from happening? Adding 'unique' to the
Employee FK makes it so Employees can only join one Team).

The code I'm using (irrelevant parts removed):

from django.db import models
from django.contrib.auth.models import User

class Employee(models.Model):
name = models.CharField(max_length=30, unique=True)
user = models.ForeignKey(User)

class Team(models.Model):
name = models.CharField(max_length=60)
members = models.ManyToManyField('Employee', blank=True,
through='TeamMember')

class TeamMember(models.Model):
employee = models.ForeignKey(Employee)
team = models.ForeignKey(Team)
is_leader = models.BooleanField('Is Leader?')


Thanks in advance.

Please open your views.py module located inside the rchip module and

Please refer to that app's documentation to find more about the
correct setup for your urls.

telling Django to recognize a different application root url

[yrl]

I am deploying my Django projects on a host where I have the following
kinds of URLs:

http://yrl.hostname.com/djangoproject1
http://yrl.hostname.com/djangoproject2

Then, let's say I also make app A for project 1 and app B for project
2.

http://yrl.hostname.com/djangoproject1/appA/
http://yrl.hostname.com/djangoproject2/appB/

Apps A and B are unrelated and I don't want to squish them under the
same project.

My problem is that when I use any of Django's batteries-included
functionalities, like the Admin site and the Comments framework,
Django is using links like:

http://yrl.hostname.com/admin/

instead of:

http://yrl.hostname.com/djangoproject1/admin/

In other words, I need a way to tell Django that my project root URL
is "/project1/" instead of the default "/".

Is there any way to do this?

Thanks,
Yiping

Re: Proper way to strip whitespace from Charfields in a form in current version of Django?

[Andre Terra]

Why not add a custom clean_fieldname method to your class? Perhaps you
could dig into the original BaseModelForm and see how it constructs
validation, and override whatever is needed.

I'm on my phone atm, so I'll let you do the footwork alone, at least for now.

Finally, please post in English so that everyone can understand your

Re: static urls

[Valder Gallo]

Try use ../ in CSS files

If you are using one CSS by app. Or /static/ if you are using just one CSS
for all apps

:D

Pasta root

MEDIA_ROOT = os.path.join(PROJECT_ROOT_PATH, 'media')

onde a pasta "cida" seria onde eu dei o startproject

Django + nginx + windows

[Andre Terra]

Hello, guys

I just wanted to share: Setting up django + flup + fcgi + nginx on windows
couldn't be any easier. Talk about "it just works"!!

Honestly, it took me about 5 minutes to set everything up, including
downloading the files.

I merged the suggested .conf file from
https://code.djangoproject.com/wiki/ServerArrangements to the default
nginx.conf file, changed a couple of ports and paths, ran manage.py  runfcgi
and it simply worked :O

I recommend all of you who haven't given it a chance, to try it out for some
small app or even for development.


Cheers,
A very happy André Terra

Scientific Linux with django running through apache and fastcgi

[Rick Beacham]

here is my problem..

After trying to run on localhost/hello/ through lynx I get a 500. This
is what htttpd error_log file prints out.

I am not using socks, i am using tcp host port 3303.

I'm not sure if its a permission problem or SELinux issue.

fcgi is working by itself without apache look at it here.

Manually ordering items in relation to siblings

[Andre Terra]

Hello, everyone

Assume the following models (dpaste.com [1]):

class Account(models.Model):
"""
Account model for categorizing entries from each SAP import,
and eventually sorting, grouping, filtering data.

"""
code = models.CharField(max_length=255, primary_key=True)

group = models.ForeignKey('AccountGroup', blank=True, null=True,
  related_name='groups')

description = models.CharField(max_length=512, blank=True, null=True)


class AccountGroup(models.Model):
name = models.CharField(max_length=512, blank=True, null=True,
verbose_name=_('Name'))

parent = models.ForeignKey('AccountGroup', blank=True, null=True,
   related_name='children')

is_subgroup = models.BooleanField(default=False, editable=False)

def save(self, *args, **kwargs):
self.is_subgroup = False

if self.parent is not None:
self.is_subgroup = True

return super(AccountGroup, self).save(*args, **kwargs)

I would like to be able to manually specify an order for AccountGroups in
relation to their siblings, so that I can have a final result of something
like the following pic (which describes a set of groups and accounts, with
the latter being the rightmost, M0-format codes.

http://img200.imageshack.us/img200/9423/groupsandaccounts.png


As you can see from the picture, accounts can be located under any number of
groups, and neither Accounts nor AccountGroups are not sorted naturally.

Short of using something like django-treebeard[3], how can I write a
solution for this use case?

Thanks in advance for all your help!


Cheers,
André Terra

Re: : Multipoint field only shows the first point in OSMAdmin

[sylvain_grodes]

Ok, I just tried with the dev version of OpenLayers and it just works!

The problem comes from openlayers not interpreting correctly
GeoDjango's WKT syntax

more here: http://trac.osgeo.org/openlayers/ticket/2670

My workaround is the following:
- checkout a dev version of openlayers
- build it and make it reachable anywhere on the internet
- edit django/contrib/gis/admin/options.py and update openlayers_url
to your own url

Hope this can help someone else

If True, it will store a log of every query and statistics about that
query in django.db.connection.queries. IE, with settings.DEBUG, you
will have a (deliberate) memory leak until the connection is
destroyed.

DeprecationWarning displayed in test, not in dev

[Tom Evans]

Hi all

I recently upgraded one of my apps to the next iteration. This used a
third party library, which started spewing out DeprecationWarning
messages when I deployed it to the test site. None of these warnings
appeared when I was developing, and I was wondering if there was a
reason why. The only noticeable difference I can see between the two
is that I use python 2.7 in development, and 2.5 in test/production -
dev is on my laptop, where as the others are on dedicated boxes.

In both cases, the required packages are installed into a virtualenv
via pip from a requirements file, so the environment can be wiped out
and re-created, which I did on both dev and test, without changing the
end result.

So, in dev:

I think that a MonthlyReport model with a M2M to accounts is the way to go.

I propose 2 ways of affort this:
1) There is an app called django-reversion that allows you to have some kind
of version control system for your models. The admin can be able to recover
any previous version of your objects, also recover deleted objects. So if
you use this approach, you only have one report per month in your
MonthlyReport, and this report per month is the official one. So the drafts
are stored by django-reversion. But, frankly, I don't know how performance
will be with 1.5million entries.

2) As you say, use a MonthlyReport model with an is_official flag, and when
the admin select the accounts in order to do the current report display a
dinamic form with a single field (RadioWidget would be the most
appropiated). So this dynamic form should looks like:

(if there is no official report for the current month the form should ask:)
 *Create a new dratf
 *Create a new official

(otherweis:)
 *Create a new draft
 *Override current oficial report

In my code I've been careful to only use iterators, etc and should

inserts is there any accumulation of objects going on ? For instance
is commit only occurring after n saves.


here is a stripped down version.

[GEODJANGO]: Multipoint field only shows the first point in OSMAdmin

[sylvain_grodes]

Hello, today I'm facing a problem which coud be a Geodjango/OpenLayer
or Django.

How to reproduce:

* in your model create a class:

from django.contrib.gis.db import models

class Track(models.Model):
track = models.MultiPointField(srid=4326)


* in your admin.py add:
admin.site.register(Track, OSMGeoAdmin)


* create a track object with the shell
from django.contrib.gis.geos import MultiPoint
from django.contrib.gis.geos import Point

myTrack = Track()
point1 = Point(-61.067853, 14.607004)
point2 =  Point(-61.063573, 14.609091)
multi = MultiPoint(point1, point2)

myTrack.track = multi

multi.save()

* look in the administrator: you will see only one point even if in
the source i can read MULTIPOINT(

Anyone has already seen this?

Am I doing something wrong?

Hi,

There's nothing to do except make sure your LANG is set to something such as 
en_US.UTF-8.
If you are using apache, check you /etc/apache2/envvars

Re: setting up homepage, and naming/organizing apps

[Alex Hall]

Thanks for all the replies.

1. I did plan to have a dynamic homepage; its most complex section
will be to display the most recent ten additions to the articles
table. It sounds like I can just create a views directory inside my
site directory and use that. I was hesitant to do this simply because
django didn't create one, and it seems to create what I should use.
That is, if it didn't give me a views folder, I figured there was some
other way to do it than to use a views folder.

2. I will keep my app directory structure for now and modify as necessary.

Re: Django site broken after Debian upgrade

[Andre Terra]

Glad you got it figured out, after all!

Unfortunately, the django book is indeed lacking a serious update. The
official docs are still the go-to place for learning how to use django.

Users in this list have been active in writing new pages to the official
Wiki, but there's also a huge void in terms of how-tos and tutorials on that
media.

For now, what I will recommend is that you ask around in #django (
irc.freenode.net), here on django-users and on Stack Overflow (SO). FWIW, I
think SO is flooded with questions about third-party apps, so I don't go
there often to answer questions, as I have virtually no experience in said
apps.

However, if the questions you post to this list come with the right tone and
a decent explanation of the issues you are encountering, most of us will be
glad to jump in and lend a hand.

Bingo!  That was the problem.  After clearing out the offending copied
admin templates I was able to restore the CSRF code and I'm back on
the road again.

Thanks again.  I'm glad I won't have to ditch Django.  I like the
interface it provides better than anything I could have rolled myself.

As a side note, I'm guessing that turning to the "newer" version of
The Django Book won't do me much good, as the dates on the chapter
list seem to indicate that nothing has been done since the spring of
2009, and the book is incomplete (and out of date).

Each Entry has an FK to Task, which in itself has a timestamp, so I think

This looks like a very useful clue.  I set this up years ago to handle
my company's financial books, and haven't touched the code since then,
so I'm having to do some digging to reconstruct how I did things.
Much of what I did was following the instructions from the Django Book
(written, as I recall, by the creators of Django), and I see that it
said in chapter 6: "To customize Django’s admin templates, simply copy
the relevant stock admin template from the Django distribution into
your one of the directories pointed-to by TEMPLATE_DIRS."  Apparently
that was dangerous advice, if it's at the root of the breakage I've
run into (and I see that this advice is no longer included in the
newer version of the book under development).

Thanks for the tip, Andre.  I'll keep digging and see if I can
extricate myself from this mess.

Cheers,
Bob

Actually, I just paid a visit to Django's installation guide [1],
which advises installing Django using the package management system of
your OS distro, as the first of three recommended installation

It is possible to list data from a database view in Django?

[Andre Lopes]

Hi,

I'm new to Django. I'm in the process of test the features of Django
to move a site from PHP to Python/Django.

I have a database view that is the result of many joints between
tables, I only do SELECTs to this view, the data is inserted via a
Script that will populate the various tables. I only need to show the
data in this view, how Django handles the listings of data in views? I
have to define the view in the model?

Please give me a clue.

Re: setting up homepage, and naming/organizing apps

Hello all,
I was on this list a few months ago, but was unable to get a
django-friendly web host. I am now helping with a site on Bluehost,
which does support django, and I am hoping to be given permission by
the guy in charge to use django instead of php for our project.

I have been going through the tutorial, adapting it to my project as
necessary, and have a couple questions.

1. This must be glaringly obvious, but how do I use django to load my
homepage (index.html in the public_html root)? I understand about
views and url matching, but there is no views.py in the main directory
and I am not sure if I am supposed to create one or not. In other
words, how does django know where to find the page to load when a
visitor simply goes to mysite.com, instead of
mysite.com/something_to_match?


Normally you would build a dynamic home page but here is a simple 
sequence ...


1. Write a hello world index.html which will be your "home" page

2. Put it in /templates where  is the directory 
containing settings.py


3. In urls.py where your other patterns exist scroll to the end and add 
this ...


# note the += which appends this pattern to the others.
urlpatterns += patterns('',
# empty string r'' matches any URL so put it last
(r'', 'flatviews.flatpage'),
)

4. Create a new file flatviews.py in the  directory like this ...

from django.shortcuts import render_to_response

def flatpage(request, pagename='index.html'):
return render_to_response(pagename)

Should do the trick. Your mission is now to build your home page from 
inherited templates and database content via the django template language.





2. The project I am working on has a few tables: media, articles, and
authors. An article can have one author and one or more rows in the
media table associated with it. I currently have an app called
"tables", in which I plan to define the three tables in models.py (I
am only working with authors as a test). All my views, urls, and so
forth will be inside this tables app. Is this generally recommended,
or should I have an app for each table?


The layout principle as set down by James Bennet in Practical Django 
Projects is to keep it simple. In other words you would begin by keeping 
it all in a single app directory.


If it starts to get complex you can refactor into separate directories 
eg all views in a views directory etc. In there you can have different 
files for different groups of views which might have some similarity 
such as all needing to import the same particular model or models. 
Models too can be split into different files in a separate models 
directory. Keep stuff together which belongs together.


Finally, he says to try and segregate your own project into separate 
apps in their own directories with their own urls, models, views etc on 
the basis of some sort of standalone functionality.


My own take on this is to not worry when you are a beginner because it 
will become obvious when things are getting messy and you suddenly 
realise all you have to do is unclutter directories into a nice and 
comfortable hierarchy.


One example above is flatviews.py which I said to put in the  
directory. If you decided that was getting too cluttered you could make 
a views directory and move it into /views/flatviews.py and 
refactor urls.py so it called 'views.flatviews.flatpage'


Good luck

Mike


The tutorial has two tables
defined, but the urls are all /polls/[something], whereas my urls
might be /authors/, /author/[id], /article/[id], and so on (not
sharing /[app_name]/... like the tutorial does). I hope that made
sense!

Dont you have a urls.py in your project? Something like this will take you
to the "/" of the site:
url(r'^$','index' ,{}, name="index"),

Since all the 3 tables relate to a 'single' functionality - this is fine.

I don't know why you mention "index.html in the public_html root". Django 
pages are dynamic and are not served from the html_root. You could set up 
your webserver to look there for URLs matching / only, but are you sure you 
don't have *any* dynamic or database-based content in your home page? Not 
even a menu? Seems strange. Normally, you would just set up a url to match 
r'^$' and route to a view in the normal way.

No, you have it right. These three models are clearly all related, so belong 
together in one app.

Re: static urls

[Anoop Thomas Mathew]

Hi,

Depends on how you configured STATIC_URL in settings. If / is there in the
STATIC_URL, then no need to add it.
Add it with STATIC_URLS, that is the standard practice.
