Problem logging in to admin using Safari

[Pieter Claerhout]

Hi all,

I've started playing with Django and stumbled upon a very strange problem.

I've created a small test application with just a single app in there
which renders some static HTML. I've also enabled the automatic admin
side which seems to work just fine when I run the development server.

I've then moved the whole thing to MacOSX Leopard using the built-in
Apache and mod_python 3.3.1. Everything works fine as well, except for
the admin side on Safari. Whenever I try to login to the admin side on
Safari, I get the message:

Looks like your browser isn't configured to accept cookies. Please
enable cookies, reload this page, and try again.

If I try the same on Windows IE, Windows FireFox, Mac Firefox, it
works just fine.

I've tried emptying the cache of safari, but that didn't change a
thing. I've also recreated the db and flushed the session table, but
again, no difference.

Here's the mod_python config I'm using:



ServerName django_test.local


SetHandler python-program
PythonDebug Off
PythonAutoReload Off
PythonInterpreter django_test
PythonHandler django.core.handlers.modpython
PythonPath "['/web_projects'] + sys.path"
SetEnv DJANGO_SETTINGS_MODULE django_test.settings


Alias /media "/Library/Python/2.5/site-packages/django/contrib/admin/media"

AllowOverride None
Order allow,deny
Allow from all


SetHandler None




Anyone an clue what could be causing this? I'm using django-trunk (rev
7725) on MacOS X 10.5.3.

Cheers,


pieter

ordering in the ManyRelatedManager object

[Bing]

Hi,

I have a general question regarding the ordering in
the ManyRelatedManager object.  For example,
There are two classes in my model:  one is
called Book for books and another is Author for authors.

A many-to-many field is defined  in class Book
authors = models.ManyToManyField(Author)

In database, the many-to-many relationship
is described in an additional table book_author
with three columns: (id, book_id, author_id)

Now for a Book object b, both b.authors.all() and b.authors.iterator()
are sorted in the order of book_author.author_id.
But what I want is to retrieve the authors of b
in the order of book_author.id because this is
the right order of the authors.

Any solution? Many thanks in advance!

custom form with admin look and feel

[chefsmart]

I'm using django svn trunk. I have created several custom forms that
show up in the admin section of the website. However, these forms look
nothing like the admin forms. I tried extending change_form.html
template - unsuccessfully.

Does anyone know what my template should contain to achieve admin look
and feel.

Thanks...

Any suggestions on encryption methodology?

[Tye]

Say - for the sake of example - I'm accepting highly sensitive  
financial data through a form over SSL.

Staff members need to retrieve that information at a later time.

Meanwhile, I want that data to be encrypted while it's sitting in the  
database. What do you suggest?

dynamic value of a ModelChoiceField

[[EMAIL PROTECTED]]

In a form, I have a field defined as ModelChoiceField

class myForm(forms.Form)
  myfield = forms.ModelChoiceField(MyClass.objects.all())
 myfield2 = forms.CharField()

My problem is that I cant seem to dynamically set the value that the
user selected for this field. When ever, user edits the record, this
select list always gets set to no value instead of the value that the
user had originally selected.

the input text field has no problems in showing the saved data
correctly.

am I missing something ?

thnx,

Re: dynamically filling ChoiceField

[Rishabh Manocha]

Some more details would be good, but off the top of my head, something like
this might work:

def my_view(request):
   form = MyForm()
   form.fields['mychoice'].choices = ((1,'ABC'),(2,'XYZ'))

I havent' been able to test this out, so make sure you do before you using
it.

You can of-course do any amount of pre-processing before you apply that
tuple.

Best,

Rishabh

dynamically filling ChoiceField

[Calvin Dodge]

I've been tearing out what little hair I have left trying to figure
this out.

How do I dynamically fill a ChoiceField by filtering on a value known
to the URLView? Every "dynamic fill" example I've found assumes the
form knows it all - I haven't seen anything which shows me how to pass
that value from the view to the form.

Help? Please?

I was going for the full name, but using first_name as a starting
point, I figured if that was blank, they probably both were.

Thanks for pointing out get_full_name and for the introspection stuff
too, just what I needed.

Help with mod_python and dynamic vhosts

[Brian Ritchie]

Hello all,

My first post to this mailing list.  I didn't see this in the archive.  It
this was covered before, sorry about that.

I have a webserver (Ubuntu, Apache2) with dynaminc vhosts setup. I'm
experimenting with django a bit and I tried to setup the byteflow blog by
adding a subdomain of http://blog.mysite.com (note: not the real URL :P).  I
followed the instructions shown here...

http://blog.leschinsky.in.ua/2008/02/05/byteflow-installation/
http://blog.leschinsky.in.ua/2008/02/05/byteflow-setup/

Installation went smoothly but the apache2 setup isn't right. Those
isntructions are meant for a more simple apache2 setup. I'm not the most
knowledgeable when it comes to setting up Apache2 vhosts (using the
sites_available and sites_enabled directories), so I can't get it to work. I
had some fellow programmers help me but they were not familiar with this
type of apache2 setup either. Here is the basic byteflow config that I
used...

NameVirtualHost *:80

   ServerAdmin [EMAIL PROTECTED]
   ServerName blog.mysite.com


  SetHandler python-program
  PythonHandler django.core.handlers.modpython
  SetEnv DJANGO_SETTINGS_MODULE settings
  PythonDebug On
  PythonPath "['/home/me/django-src/byteflow' ] + sys.path"


Alias /static/ /home/me/django-src/byteflow/static/

  SetHandler None


Alias /admin-media/
/home/me/django-src/django_trunk/django/contrib/admin/media/

  SetHandler None



ErrorLog /var/log/apache2/byteflow.log
LogLevel warn
CustomLog /var/log/apache2/byteflow.log combined
 

That *almost* works. Under certain variations of this configuration, I can
see the blog and I know that the blog is functional. The problem is that
this config causes all of my dynamic vhost domains to display the blog
(eek!). I've tried variations of this where I placed my full URL
blog.mysite.com:80 for the NameVirtualHost and VirtualHost lines, including
removing NameVirtualHost from this config. It seems that I can get either
one of two results. I can get the blog to appear on all of my sites or I can
get the blog.mysite.com to point to /www/blog.mysite.com/ (which is blank)
like the rest of my dynamic vhosts.

My dynamic_vhosts config has this...


Options Indexes FollowSymLinks MultiViews
DirectoryIndex index index.html index.php index.phtml

AllowOverride All
Order allow,deny
Allow from all


 #the IP of my server
# Get servername from Host: header
UseCanonicalName Off

# this log format can be split per-virtual-host based on the first field
LogFormat "%V %h %l %u %t \"%r\" %s %b" vcommon
LogFormat "%V %h %l %u %t \"%r\" %>s %b \"%{Referer}i\"\"%{User-Agent}i\""
vcombined
CustomLog /var/log/apache2/access_vhost_log vcombined

#
# include the server name in the filenames used to satisfy requests
VirtualDocumentRoot /www/%0/public_html
VirtualScriptAlias  /www/%0/cgi-bin
#
#   This configuration can be changed into an IP-based virtual hosting
#   solution by just turning UseCanonicalName Off into UseCanonicalName DNS.
#   The server name that is inserted into the filename is then derived from
#   the IP address of the virtual host.


So I'm looking for a mix of dynamic vhosts for all of my domains except one
select vhost that gets handled by mod_python.
Any insight would be helpful.  Thanks.

Brian

media server implementation - context processor, custom template tag, or custom filter

[alex]

I already have {{ MEDIA_URL }} set in html, css, and js templates and
that's working great. I would like to start setting far future caching
headers on media files based on the git abbreviated commit hash for
each file. i can think of three options for implementing this and
would appreciate feedback, especially in regard to the processing or
performance penalties any of these approaches may incur. i've
implemented proof-of-concept versions of all of them in development
and they at least accomplish what I want, though I haven't yet done
any benchmarking.

as part of the production deployment process, a script is run which
essentially does the following: for every static media file, find the
git abbreviated commit hash which looks like "857vb4". the results are
written to disk as a python dictionary:

STATIC_ASSETS = {
"/media/image/button.png": "/857vb4",
"/media/image/submit.png": "/219cb3",
etc.
}

the dictionary has approx 100 entries and may grow to 200.

all of the approaches below generate html like this:

http://media.example.com/857vb4/media/image/button.png;>
http://media.example.com/219cb3/media/image/submit.png;>

but the actual paths on disk do not include version numbers. apache
has a re-write rule which removes the revision information, so that
clients can be told to cache the static files for a long time into the
future because whenever the file changes, the revision number in the
url will change. here are some ways i've come up with for adding the
revision info to the static file urls.

1) simple string filter
templates look like this: 
and the template filter is approx:

@register.filter
@stringfilter
def get_file_version(value, arg):
if arg in STATIC_ASSETS:
value = STATIC_ASSETS[arg] + arg;
else:
value = arg;
return value

2) simple custom template tag
templates look like: 

template tag code:

@register.simple_tag
def get_file_version(arg):
value = arg
if arg in ASSET_LIST:
value = ASSET_LIST[arg] + arg;
return value

The third option would be a custom context processor which adds
template variables to each page that are tied to the filename.

Are these approaches reasonable or do they incur too much processing
for, say, a page that has 10 or 20 static files (images, js, css)? Is
there a better way I'm overlooking? I'm trying to avoid approaches
which rename files on disk or do find-and-replace operations on
template files.

Any feedback appreciated.

[Nathaniel Whiteinge]

Stuart Grimshaw wrote:

It looks like you're trying to use a ternary operator here, but only
Python 2.5 and later has one (and the syntax is different [2]). The
good news is that you can accomplish what you want without using a
ternary operator since Python boolean operators return values instead
of just true or false [1]. Try the following instead::

swap_players_form.fields['side_a'].choices = [(
player.player.id,
player.player.first_name or player.player.username
) for player in side_a]

I similar idiom that I make frequent use of if I don't require that a
user enter a first or last name and therefore need to use the username
as a fallback is the following. (Note the built-in Django method
``get_full_name`` always returns a string, but the first name or the
last name can be empty.)::

user.get_full_name() or user.username

.. [1] http://www.diveintopython.org/power_of_introspection/and_or.html
.. [2]

The Python 2.5 ternary operator syntax::

value_when_true if condition else value_when_false

is equivalent to::

cond ? valueIfTrue : valueIfFalse

User Templates

[Dan]

I am looking for a way to enable users to make template to control the
presentation of reports that they would require. I am looking for the
most flexible to them and most secure to me way to do this. I want to
be careful since the data serve would come from my domain and thus be
vulnerable to origin-domain tricks. I can't have users write django
templates as they could put infinite loops or other nastinesses in
them.

Do you have an idea how I might achieve this? The resulting report do
not need to be HTML, if something nice can be made with PDF or
anything else, I'm open to it.

Choosing between User.first_name/last_name & username

[Stuart Grimshaw]

As part of my sign up process, I don't require that people fill in
their first/last name, and just choose to show the username if no name
is entered.

Unfortunatly, I've come across a bit of code that I can't do this in,
which has got me thinking, I'm doing this all over the show, so there
must be a better way of doing it.

Ideally I'd like to just override the __unicode__ of the User method,
but I've been reading about the kerfuffle involved doing that, so does
anyone have any other bright ideas?

The problem that kicked all this off was that I was trying something
like this:

swap_players_form.fields['side_a'].choices = [(player.player.id,
player.player.first_name == '' ? player.player.username :
player.player.first_name) for player in side_a]

but it was throwing syntax errors on "player.player.first_name == '' ?
player.player.username : player.player.first_name)", if I could get
this method to work for now to let me move on that'd be a start.

Any ideas anyone?

Complex URLs and numerous GET variables

[[EMAIL PROTECTED]]

Hi

I've got a bit of a problem as I'm now wishing to use more complex
urls on my app and I'm not sure how to go about doing it the Django
way.

I've got an online store that can have filters placed on it like
Price, Make, Category.

Thing is when I wanted to use one of those it was simple:

example.com/shop/cat/widgets

However, I now want to use all of them.  I did think I could do:

example.com/shop/widgets/250-500/FoobarCompany

But it seems dodgy.

Can anyone point me in the right direction on this?  I'm a bit lost.

Really appreciate your input. :)

How best to delete one of multiple records?

[Kenneth McDonald]

I have a list of records, and I'd like the user to be able to delete  
any given record by pressing a button. My current strategy is to have  
each record in its own form (so that pressing the submit button for  
that form would delete the record), and have each form contain a  
hidden field identifying the corresponding record via a unique key so  
that I know which record to delete. However, this is very crude, and  
no doubt indicative of the fact that I'm still just starting to learn  
Django. What would people suggest as better alternatives? Feel free to  
point me to documentation--I don't mind doing the reading, it's just  
finding the relevant material that's a problem (there's so much of  
it :-) ).

Thanks,
Ken

First, you are overwriting, not adding to, 'string' on each iteration of the
loop.  Second self.demandeur is a ManyRelatedManager which you cannot
iterate through.  If you want to iterate through the items in the set you
have to call .all() on the ManyRelatedManager.  Something like (untested)
should do it:

def dem(self):
return ' '.join([str(agent) for agent in self.demandeur.all()])

Re: Add db tables on-the-fly

[Ned Batchelder]

Creating a table per user is definitely going against the grain in a 
relational database world.  You'll be much happier with one table to 
store the data across users, with a foreign key to the users table to 
keep everything straight.

render_to_response doesn't use a RequestContext whereas the generic views do.

To enable this in render_to_response try:
from django.template import RequestContext
...
render_to_response('some/template.html',
context_instance=RequestContext(request))

Hope this helps,
Nick

Re: very heavy problem with edit_inline

Is it possible to add a link on my foreignkeys to edit the external reference?

It's strange it's possible to add a new referenced object but not open
an existing one and edit it. It should be very very useful.

Re: auth context processor setup

[Vasiliy Gladkov]

Maybe you forgot to use context_instance parameter in render() call?
If you want to use context processors, it must look like

return render_to_response('template.html', context,
context_instance=RequestContext(request))

context_instance parameter passes contexts from processors to your
templates

Re: Add db tables on-the-fly

It is not really a problem
It's for a multi user app. For each new users, i create a serie table

If it's easy to create table on-the-fly when a new user registers, i
prefere.

but I do not see how

Re: Having problems with regroup on datetime

Not sure what happened, but I fixed this by doing this:

New site - any comments please on structure / bugs/ security holes etc etc.

[Richard Green]

Hi there - I've just put a noddy site together so that I could give
myself a real goal for getting a django based site running. I've got a
few bigger internet ideas but I thought I'd do something small to
start with to test the feasility of writing it in django, before
embarking on a route using technology that might not be fit for
purpose... Obviously if I've reached this point then its fair to say
that I think I may well be using django for the bigger projects (or
I'd be posting on another site!!)

Anyway - my site is at : www.scareports.com  - I'm trying to collect
stories of (basically) horrid things that happen at airports mainly
due to the draconian security measures that governments will think
will stop terrorists etc etc. I remember a time when flying was fun
but now it seems to be a lottery just getting to the airplane. I chose
this subject as it seems everyone has a story to tell ( a friend of
mine - for example - was told to put her BABY through the luggage xray
machine; thankfully she flatly refused )..

If you have 5 minutes - and I'm not trying to pimp the site but just
my usage of django - please drop in and let me know if you see any
problems / faults etc. I'm especially interested in security holes of
any type. I've set up the emails via google for apps and I'm not sure
if it's activated yet so don't write to me at [EMAIL PROTECTED] but
please comment on this thread.

Multiple fields without manytomanyfield?

[Xan]

Hi,

Suposing you want a model A with several and indetermined number of
integer fields. Is there any possibility of defining A without
creating a Integer class and then add ManyToManyField(Integer) in
class A?

Thanks a lot!
Xan.

Having problems with regroup on datetime

[Darthmahon]

Hi,

I am trying to group a list of events using the regroup template tag
as such:

{% regroup event_list by date as events %}

{% for event in events %}
{{ event.grouper.day }}
{% for event in events.list %} {{ event.title }} {% endfor %}
{% endfor %}

Now, in my model for Events, I am using a datetime field so when I do
the regroup, unless the events are EXACTLY the same time, they will
print seperate H2's.

Using the code above it looks like this:

Saturday 22nd
- Event 1

Saturday 22nd
- Event 2

I want it to look like this:

Saturday 22nd
- Event 1
- Event 2

Any ideas? I know it has something to do with the datetime field
having the date and time, I just want it to have the date so I can
regroup on that.

Cheers,
Chris

Add new context processors [Trick]

[Kless]

To add any new context processor, write this on your settings file:

---
from django.conf.global_settings import TEMPLATE_CONTEXT_PROCESSORS

TEMPLATE_CONTEXT_PROCESSORS = TEMPLATE_CONTEXT_PROCESSORS + \
('project.app.context_processors.name',)
---

So, neither that variable is overwritted neither you have to copy it
from the global settings file.

Re: Use values of Site module on templates [SOLVED]

[Kless]

At the end, I'll get these variables directly from the Site module.

And to access to them, can be made using templatetags or context
processors -that is better for this case-.

* Templatetags
---
from django import template
from django.contrib.sites.models import Site


register = template.Library()
current_site = Site.objects.get_current()

def site_domain():
return current_site.domain

@register.simple_tag
def site_url():
return "http://www.%s; % (site_domain())

@register.simple_tag
def site_name():
return current_site.name
---

* Context processors
---
from django.contrib.sites.models import Site


def site(request):
"""Adds site-related context variables to the context.
"""
current_site = Site.objects.get_current()

return {
'SITE_NAME': current_site.name,
'SITE_DOMAIN': current_site.domain,
'SITE_URL': "http://www.%s; % (current_site.domain),
}

Re: auth context processor setup

[Vasiliy Gladkov]

You have to enable auth middleware and application in settings.py -
http://djangobook.com/en/1.0/chapter12/
Then you can use user specific variables in your templates -
{{ user.username }}, {{ user.is_staff }} and so on

Karen, thanks a bunch! It was the exec permission, not read, but your
e-mail gave me the hint. ;)

I don't know how it happened that it lost the exec perms, but I got it
'fixed' now.

What problem are you trying to solve? This really doesn't sound like a 
common Django idiom.

If you insist, you could probably do (using 0.96):

   from django.core.management import syncdb
   syncdb()

I think you've misunderstood how signals work; you can selectively do
something only when a certain specific class is first loaded.

Re: Extending the method that is called the first time a model is deployed.

[mwebs]

Hi,

It seems as if these signals have to be used in management.py, but
what I need is something I can use directly in my model code.
Something like overloading a method. The fact that this should be
happen in the model-class is very important. E.g I dont want every
model to be registerd in my "meta-model" Apps only some of my models.

One Idea was to implement this kind of registration everytime a model
is instantiated and checking if there is already an entry. But this a
hack because I really need this only one time (the first time the
model is deployed.)

any ideas?

Thanks, Toni

has_perm() equivalent for group membership...

has_perm() checks whether a user has_certain_permission. Is there a

belongsTo_certain_group ?

Do not use the foreignkey as core, but another field. This works:
- - - - -
user = models.ForeignKey(User, unique=True,
edit_inline=models.STACKED, num_in_admin=1,min_num_in_admin=1,
max_num_in_admin=1,num_extra_on_change=0)

nomeditta = models.CharField("Nome Ditta", max_length=100, core=True)

Re: very heavy problem with edit_inline

> If all fields marked core are blanked, then the object is deleted.

If you have a foreignkey with core=True, among others, it deletes also
if another core field is not blank.

I've tried also with my user:
- - - - -
user = models.ForeignKey(User, unique=True,
edit_inline=models.STACKED, num_in_admin=1,min_num_in_admin=1,
max_num_in_admin=1,num_extra_on_change=0)

nomeditta = models.CharField("Nome Ditta", max_length=100, core=True)
- - - - -

and now it works.

If there's more than one core=True field it doesn't work: if one of
them is deleted, the object is deleted.

expecially there's problems if the core=True is set on the ForeignKey.
Maybe it's the same problem with extending the users in another
threads.

If all fields marked core are blanked, then the object is deleted.

BTW this core thing is gone in newforms-admin.  There's a 'delete' checkbox
next to edited-inline objects that lets you delete them in a more
straightforward manner.

If I put core=True on more than one field, and if 1/3 of those fields
is blank, the object is deleted, or it needs 3/3 fields blank to
delete?
