Hi,

I'm new to Django. In my system I have Python 2.6 and Python 2.7
installed, but due to some inconsistencies in Python Path I will
uninstall the Python versions and install again.

What I need to know is if Python 2.6 will work without problems with Django 1.3

Best Regards,

Being an unsupported setup, I'd say you are in unexplored territory here
so you will need to find the potential shortcomings by yourself.

One possibility would be to create a test suite that covers all your use
cases of cross-DB relationships.

Re: Django & Two Factor Authentication (2FA)

2011-03-24 Thread pokecho

Hi Sam,

Thanks for the note. All the 2FA systems I have used have single field
for both the password and the token.

>Is a separate passcode field really necessary?

However, from a usability standpoint I believe decoupling the two
would make it easier for the user to recognize that the token/PIN is
fed to and consumed by the system through a different field. So I am
thinking about balancing usability and security. If the token and
password live in the same field, we increase the margin of error for a
non-techie user who must enter a known value(the password) and a
dynamic (possibly all numeric) value (i.e. the token).

>The extra password doesn't add much security; it is only there to placate 
>Windows requirements.

Aside from Man-In-the-middle attacks and Trojan raider, which present
challenges for all authentication protocols, the security is
heightened because the second value is dynamic and expires after a
specified time.

So how do I configure contrib.auth to authenticate against three input
values "username"(static), password(static/encrypted) and PIN/
token(dynamic/encrypted)? That is the question.

Django 1.3 should work just fine on python 2.6. Django is compatible
with python 2.4+, but not 3.x yet.

There are a number of CMS options for django.

You can find a nice comparison here:
http://djangopackages.com/grids/g/cms/

I've used Mezzanine and it's very good, but might not be the best for
a large newspaper site.

It all depends on your needs, so I'd probably try out a couple of the
CMS's on that list to figure which you like best and then customize it
from there to fit your needs.

Re: High availability deployments

2011-03-24 Thread Kristaps Kūlis

 See this blog post: 
http://rambleon.usebox.net/post/3279121000/how-to-gracefully-restart-django-running-fastcgi
 TL;DR : just send SIGHUP to flup process (pidfile option to fastcgi),
like this:
 kill -SIGHUP `cat /path/to/flup.pid`
 I suggest using Gunicorn, as it handles graceful reloads better than
flup in my experience (trought newest editions of flup handle graceful
reloads with SIGUSR).
 Also: graceful reload is impossible when you are running database
schema changes as that is not atomic process. Put some nice 502 error
page like: where are updating teh codez, drink coffeee!

decorators and generic views

2011-03-24 Thread Ian Stokes-Rees

I think with the move to class-based Generic Views it is necessary to update 
this documentation:

Limiting access to generic views 

To limit access to a *generic 
view*, 
write a thin wrapper around the view, and point your URLconf to your wrapper 
instead of the generic view itself. For example:

from django.views.generic.date_based import object_detail
@login_requireddef limited_object_detail(*args, **kwargs):
return object_detail(*args, **kwargs)

I am trying to put an @login_required decorator around ListView.as_view(...) 
but not having any luck.  Advice on how properly map from urls.py to a 
function in the wrapped view would be appreciated.  My current best attempt 
is below

Cheers,

Ian

urls.py BEFORE:

from gridportal.wsmr.models import WSMRTask
from gridportal.wsmr.views  import list, create, view, edit, 
copy, delete, reset

urlpatterns = patterns('',
(r'tasks/?$' , ListView.as_view(model=WSMRTask)), # 
working, but no access control

urls.py AFTER:

from gridportal.wsmr.models import WSMRTask
from gridportal.wsmr.views  import list, create, view, edit, 
copy, delete, reset

urlpatterns = patterns('',
(r'tasks/?$' , list()), # not working

views.py AFTER:

@login_required()
def list(*args, **kwargs):
return ListView.as_view(model=WSMRTask)

I get the exception:

_wrapped_view() takes at least 1 argument (0 given)

I'm fairly experienced with Python for backend, non UI/UX tasks but am very new 
to trying to do any UI work other than command lines. This'll come off as a 
very newbie question, and it is.

I need to take an existing Java/Swing UI and wrap it inside of Django to 
provide authentication, customer support, etc. I've got a pretty good handle on 
most of this, except for:

What is the best Python approach to writing a web UI that includes 
dropdown menus, radio buttons, etc?

It may be that Django will do this for me, but I've not figured out how to do 
so yet.

Thanks

-David

Re: Auto refresh of page for one user on other user's update

2011-03-24 Thread Marwan Al-Sabbagh

I'm working on an application that has a similar requirement. If you can
wait for a few weeks, I'll probably have it ready and released sometime next
month. I'll be releasing it as an open source project specifically to work
with django. If it's something you're interested in shoot me an email and
I'll make sure to keep you posted once I release it.

cheers,

It is available at http://www.aryehleib.com/CHM.html

I've also made available there chm files for earlier django releases

Re: How to install psycopg2 using Pip?

Hi Andre --

This indicates that you don't have the development packages for
PostgreSQL. psycopg2 is written mostly in C, and needs to be compiled
and linked against PostgreSQL. It does this by running a command
called pg_config, which is part of the PostgreSQL dev package.

You haven't indicated which platform you're on, so I can't tell you
exactly how to install the dev packages. On Ubuntu, it'd be "apt-get
install libpq-dev", for example.

Since this isn't really Django-related, you might want to also take a
look at the psycopg2 docs, especially the parts about building
problems: 
http://www.initd.org/psycopg/docs/faq.html#problems-compiling-and-deploying-psycopg2.

Good luck,

Jacob

Re: How to install psycopg2 using Pip?

This actually has nothing to do with Python -- I'm talking about your
PATH, not your PYTHONPATH.

Short version: Type 'which pg_config' at the command line. If it is
found, then it's on your PATH. Otherwise, it's not, which appears to
be the case.

If you want to just do a temporary fix, you can follow these steps:

Run this:
find / -name pg_config 2>>/dev/null

#let's assume the result of the previous command is this:
/usr/lib/postgresql/8.4/bin/pg_config

Add that path to your PATH temporarily

export PATH=$PATH:/usr/lib/postgresql/8.4/bin

You should then be able to do the pip install.

If that doesn't work because pg_config isn't found on your system at
all then see Jacob's suggestions.

Re: High availability deployments

2011-03-24 Thread Cal Leeming [Simplicity Media Ltd]

You need to handle this within your code logic.

The problem is, when a 500 Error is given back, you don't know what actually
happened on the server side. For all you know, it could have been half way
through its task.

You need to add logic within the client side and server side code, to handle
any events like this.

Yeah, that's the easiest method, but you specifically wanted to know
how to install it with pip. That way you have to install the module
manually. But it works. ;o)

Re: Rewriting Java UI for Django?

2011-03-24 Thread Patrick McDonnell

David - I'm not sure I follow exactly what you're asking.

If you're trying to basically port a Java/Swing application to Django:
Django is a web application framework.  Python with the Django libraries are
used on the back end, and HTML is used on the front end (technically it is
possible to use something other than an HTML front end, but that woud be
very unusual).  So, in answer to your question, HTML/JavaScript/CSS/etc are
used to develop your UI.  Django does offer some utilities to make your job
easier (see the docs for forms and templates), but the majority of the UI
design must be done by hand.

Also note that Django does automatically generate an admin UI for all of
your database models.  By default, its a pretty simple CRUD interface, but
you can modify it a bit, see the docs.

If, however, you're asking how to "wrap" an existing Java/Swing application
inside of Django... That would be much more complicated, and probably not a
very good idea.

Re: Admin theme started reverting to default

2011-03-24 Thread Artem

I had something similar with several test projects running on my
machine.
The problem was - auto-generated .pyc files in django sources.. one
project user precompiled\precached files from another..
I guess I mistakenly ran dev-servers with root account, so python
could put .pyc files into that folder...
I made a simple script to remove all pyc files from sources

Override table name(s) in application deployment

2011-03-24 Thread Flo Ledermann

Hi all,

I was quite surprised that I couldn't find a way to override table
names for an application's models on a per-deployment basis (i.e. in
settings.py or some other project/site specific file instead of
modifying the models.py file of the app itself)

Although I admit all of these are rare, I think the scenarios of (a)
having table_name naming conflicts between apps or (b) working with
legacy data in existing tables or (c) renaming an app while wanting to
keep the data, would justify the "external" specification of an
application's table names.

In my case I had to rename an application for external reasons, and
would like to continue using the existing data in all my deployments.
Renaming all the tables in the databases would be quite tedious.

The only related thing I could find is http://code.djangoproject.com/ticket/891
which wouldn't help in above scenarios anyway.

What do you think? Is there something I've overlooked?

Best,

Flo

Re: Override table name(s) in application deployment

Yup, I've missed this feature quite a few times myself. I'd love to
see a good solution. Of course, it's a bit like If You Give a Mouse a
Cookie here: once you start customizing table names on a
per-deployment basis now you're going to want to customize column
names. And once you do that you'll want to customize indexes. And
then...

But yes, I'd be thrilled to see a proposal here. Double bonus points
if it doesn't introduce a new setting :) Perhaps this might become a
feature of the DB router?

Generic Foreign Keys in fixtures

2011-03-24 Thread LurkingFrog

Currently, I am writing unit tests for an application that uses
generic foreign keys.  Since the contenttypes are regenerated every
test, I was wondering the most effective way to reconcile the existing
test data with the new contenttypes PKs.

My current thinking is to make an explicit fixture the dumpdata from
contenttypes at the same time I generate the other fixtures I plan to
use in my tests.  From there, I will add code to manually update the
content types in the database to the ones in the aforementioned
contenttypes fixture and call it from the __init__.py in each
application/tests folder.  Since that __init__.py should be called
after the migrations are completed, this should make all the data line
up.

My question is whether this is the most efficient / effective way to
solve this issue.

Thanks,
Dave

Group by date: Annotate & Aggregate Query

2011-03-24 Thread James Taylor

Hi,
We're trying to do some reports of various things, and one of the 
common issues we have is to do statistics on a per day or per-month basis - A 
google search for various terms finds quite a few stackoverflow people trying 
to do the same thing and not a lot of people are getting any success without 
reverting to rawsql, which I don't really want to do.

I've made the smallest example I can here (on the end of this email), which is 
a model file and a management command that goes with it. I've created two 
linked (one to many) models, 'Article' with many 'Comments' - I want to know 
how many comments have been made on each article per day (and preferably 
efficiently without having to do a query per day with a specific filter).

Effectively, the code that I think *should work* is is:

query = Comment.objects.values( "article__title",  
"made_at__year").annotate(comments=Count("pk"))

The error i get is:

" django.core.exceptions.FieldError: Cannot resolve keyword 'made_at__year' 
into field. Choices are: article, author, id, made_at, message "

What are my options?

Best Regards
JT

Natural keys were introduced in 1.2. How would you do this in 1.1?

Or maybe there's a cleaner answer when the problem is re-stated:

How can you use dumpdata and loaddata to dump and reload fixtures when
you're using generic foreign keys?

(I work with the OP, so I'm not hijacking the thread).

Check all foreign keys before delete.

2011-03-24 Thread pbzRPA

Hi,

I am constantly running in a brick wall when it comes to deleting
records in Django. If you have one or two foreign keys it is easy to
check if they are in use, but once an application starts getting big
you can not remember which models are making use of a foreign key and
if a specific foreign key is in use.

So my question: Is there a way to check if a single model record if
being used as a foreign key in all the models in a django project? For
example:

class Stage(models.Model):
description = mo.

class Document(models,Model):
stage = models.ForeignKey(Stage)

class Server(models.Model):
stage = models.ForeignKey(Stage)

Now when I do "stage = Stage.objects.get(pk=x)" is it possible for me
to do some like "stage.?" and get back true or false if "stage" is
being used either in Document or Server or any other class that uses
Stage as a foreign Key but also only for this 1 specific record.

All I really want to do is see if I can delete "stage" without it
effecting and other records in the database.

Thanks

Re: Check all foreign keys before delete.

Once you have your 'stage' instance, try this:

stage._meta.get_all_related_objects()

You can get related models dynamically and check to see if there are
actually related instances for each of them.
Play with _meta in the shell and you'll find interesting and useful things.

Despite the underscore prefix, _meta is kept pretty stable and is used
often by normal users.

No id after save() in 1.3?

Trying to migrate from 1.1 to 1.3. My app is broken at the moment
because I'm not getting id's out of saved objects. I'm using
Postgresql/psycopg2.

I'm able to demonstrate in an ipython shell:

In [1]: import django

In [2]: django.get_version()
Out[2]: u'1.1.4 SVN-15632'

In [3]: u = User.objects.all()[0]

In [4]: ut = Utility(created_by=u, modified_by=u, name="Test1",
abbr="T1")

In [5]: ut.save()

In [6]: ut.id
Out[6]: 7L

I quit this session, and switch to 1.3, the do the same thing:

In [1]: import django

In [2]: django.get_version()
Out[2]: u'1.3 SVN-15912'

In [3]: u = User.objects.all()[0]

In [4]: ut = Utility(created_by=u, modified_by=u, name="Test2",
abbr="T2")

In [5]: ut.save()

In [6]: ut.id

In [7]: ut.id == None
Out[7]: True

And.. if I hope over to my psql shell, I can see that both were
created:

er-ca=# select * from er_utility where id > 6;
 id | modified_by_id | created_by_id |  modified_on
|  created_on   | name  | abbr | contact_id
++---+---
+---+---+--+
  7 | 11 |11 | 2011-03-24 12:02:04.341317-07 |
2011-03-24 12:02:04.341004-07 | Test1 | T1   |
  8 | 11 |11 | 2011-03-24 12:03:10.472508-07 |
2011-03-24 12:03:10.472456-07 | Test2 | T2   |


Any ideas what is going on here?

Re: Check all foreign keys before delete.

You're welcome.

I recommend (to any Django user) that you check out Marty Alchin's
"Pro Django."

Don't hesitate for a second because it was written in the ancient
times of Django 1.1 -- for Django to be changed enough that this book
becomes irrelevant it would take many years and drastic changes to the
internals of Django. This isn't a 'how-to' book like James Bennett's,
or a 'guide' like 'The Definitive Guide' by the BDFLs. It is a
serious, in-depth look that you don't need to use Django, but you want
to know to use Django effectively.

Re: No id after save() in 1.3?

I can confirm that, for me, I get the ID back just fine when using
Django 1.3. My django.get_version() just returns '1.3' (without the
SVN commit ID).

I tested this on a project I'm developing in Django 1.3, so I haven't
tried these models with 1.1.

Repetition in urls.py

2011-03-24 Thread Ryan Osborn

Hi,

I am using django 1.3 and have the following in my urls.py for a
blogging application:

urlpatterns = patterns('',
url(r'$',
ArchiveIndexView.as_view(model=Entry,date_field='created',paginate_by=10),
name='blog_archive_index'),
url(r'today/$',
TodayArchiveView.as_view(model=Entry,date_field='created',paginate_by=10),
name='blog_archive_today'),
url(r'(?P\d{4})/$',
YearArchiveView.as_view(model=Entry,date_field='created',paginate_by=10),name='blog_archive_year'),
url(r'(?P\d{4})/(?P[a-z]{3})/$',
MonthArchiveView.as_view(model=Entry,date_field='created',paginate_by=10),name='blog_archive_month'),
url(r'(?P\d{4})/(?P[a-z]{3})/(?P\d{2})/$',
DayArchiveView.as_view(model=Entry,date_field='created',paginate_by=10),name='blog_archive_day'),

P[\w\-]+)/$',
DateDetailView.as_view(model=Entry,date_field='created'),name='blog_entry_detail'),
)

I was just wondering if there was a simple way to condense this as
with django 1.2 I could add all this in to a dictionary like:

info_dict = {'model': Entry, 'date_field': 'created', 'paginate_by':
10}

Can you not set your info_dict just like that, and then rewrite it like this:

YearArchiveView.as_view(**info_dict),name='blog_archive_year'),
url(r'(?P\d{4})/(?P[a-z]{3})/$',

You can define the info_dict as above, and then use:
url(r'$', ArchiveIndexView.as_view(**info_dict),

Re: Django & Two Factor Authentication (2FA)

As Sam already said, you need to write a custom authentication
backend[1] and use it instead of the default one.

Of course, you'll also need a custom form on your login page. If you
want to use the same system in Django's admin, you'll need to create
your own subclass of AdminSite and override the form and template
used[2].

However, our id column is an integer, not a bigserial or serial. Is
that a problem?

Re: decorators and generic views

Yeah, that probably needs an update. The topic guide on Class-based
Generic views has the right examples[1]:

### In URLconf, you can do:

from django.contrib.auth.decorators import login_required
from django.views.generic import TemplateView

urlpatterns = patterns('',

(r'^about/',login_required(TemplateView.as_view(template_name="secret.html"))),
)

### Decorating class:

from django.contrib.auth.decorators import login_required
from django.utils.decorators import method_decorator
from django.views.generic import TemplateView

class ProtectedView(TemplateView):
template_name = 'secret.html'

@method_decorator(login_required)
def dispatch(self, *args, **kwargs):
return super(ProtectedView, self).dispatch(*args, **kwargs)

---

You can also decorate as_view(), like you tried to:

from django.contrib.auth.decorators import login_required
from django.utils.decorators import classonlymethod
from django.views.generic import TemplateView

class ProtectedView(TemplateView):

@classonlymethod
def as_view(cls, **initargs):
return login_required(super(ProtectedView, cls).as_view(**initargs))

This can be further abstracted into view_decorator() function[2].

Re: No id after save() in 1.3?

Ok, I think I know what is going on in here. For some reason (most
likely this is a hand made schema) the sequence which is used as the
default value of er_utility's id column is not owned by that column.
Hence pg_get_serial_sequence will return null, and this results in
currval(pg_get_serial_sequence('er_utility', 'id')) to return null.
This all is defined in django/db/backends/postgresql/operations.py:

def last_insert_id(self, cursor, table_name, pk_name):
# Use pg_get_serial_sequence to get the underlying sequence
name
# from the table name and column name (available since
PostgreSQL 8)
cursor.execute("SELECT
CURRVAL(pg_get_serial_sequence('%s','%s'))" % (
self.quote_name(table_name), pk_name))
return cursor.fetchone()[0]

Now, to fix this, first find out which sequence is used by
er_utility's id column (\d er_utility will help here). Then issue:

ALTER SEQUENCE seq_name OWNED BY er_utility, id;

Now everything should work as expected. If the same sequence is used
by multiple tables, there is unfortunately nothing you can do. A
sequence can be owned by only one column.

I will create a ticket about this problem.

Sorry, but you can't: you'll need to run inspectdb and then edit the
generated code by hand to edit out the models you don't want.

I get

er-ca=# alter SEQUENCE er_utility_id_seq OWNED BY er_utility, id;
ERROR:  syntax error at or near ","
LINE 1: alter SEQUENCE er_utility_id_seq OWNED BY er_utility, id;
^
However, I'm not sure if your answer is based on the expectation that
we've got a serial or bigserial id column. It's an integer - although
as a colleague noted, if django 1.3 had created this table, it would
have been a serial. I haven't found any upgrade notes that describe
integer id columns as a problem.

wait, it's er_utility.id ... and that does work! thanks!

although it's not clear to me who owned the sequence before. Running
\d shows the same owner for those sequences before and after... :\
