getting request.user into a ModelForm?

[Rob Hudson]

I have the following:

## MODELS

class Category(models.Model):
user = models.ForeignKey(User)
name = models.CharField(max_length=200)

class Link(models.Model):
user = models.ForeignKey(User)
category = models.ForeignKey(Category)
name = models.CharField(max_length=255)
url = models.URLField(max_length=255)

## FORMS

class CategoryField(forms.Field):
def clean(self, value):
if not value:
raise forms.ValidationError('This field is required.')
try:
category = Category.objects.get(user=???, name=value)
except Category.DoesNotExist:
category = Category(user=???, name=value)
category.save()
return category

class LinkForm(ModelForm):
category = CategoryField()
class Meta:
model = Link
exclude = ('user', 'url')

## VIEWS

def create(request):
if request.method == 'POST':
form = LinkForm(request.POST)
if form.is_valid():
link = form.save(commit=False)
link.user = request.user
link.save()
return HttpResponseRedirect(reverse('link_list'))
else:
form = LinkForm()

return render_to_response(
'links/link_form.html', {
'form': form,
},
context_instance=RequestContext(request)
)

What I don't see is a way to get the user up into my field the way I
have things set up.  I originally didn't have a user FK on the
Category model but decided I wanted it so that when adding new Links,
the Categories can be filtered by user so each user sees only their
categories.

I'm stuck here.  Any help is much appreciated.

Thanks,
Rob

I remember, that I had a problem like this, too:
   http://www.mail-archive.com/django-users@googlegroups.com/msg39059.html

You can do this to debug it:

# file which gets imported twice
import logging
logging.error('import %s %s' % (__file__, __name__))

To investigate who called this peace of code you can use the traceback
module
and print the stacktrace.

Be sure that you access the module only in one way:
e.g. always "myapp.modules". Not sometimes "myproj.myapp.modules".

defaultdict is not working on "for" template tag iteration.

[Hyungyong Kim]

Hi,

Since a few hours ago, I've suffered following problem.
I found this problem is due to collections.defaultdict.

Normal dictionary is working collectly, but defaultdict is not
working.

>>> from django.template import Template, Context
>>> t = Template("{% for k,v in data.items %}{{ k }}: {{ v }}{% endfor %}")
>>> normal_dict = {'a':1, 'b':2}
>>> t.render(Context({'data':normal_dict}))
u'a: 1b: 2'
>>>
>>> from collections import defaultdict
>>> default_dict = defaultdict(int)
>>> default_dict[1]+=1
>>> default_dict[2]+=1
>>> default_dict[1]+=1
>>> default_dict
defaultdict(, {1: 2, 2: 1})
>>> t.render(Context({'data':default_dict}))
Traceback (most recent call last):
  File "", line 1, in 
  File "/usr/lib/python2.5/site-packages/django/template/__init__.py",
line 176, in render
return self.nodelist.render(context)
  File "/usr/lib/python2.5/site-packages/django/template/__init__.py",
line 768, in render
bits.append(self.render_node(node, context))
  File "/usr/lib/python2.5/site-packages/django/template/debug.py",
line 81, in render_node
raise wrapped
django.template.TemplateSyntaxError: Caught an exception while
rendering: 'int' object is not iterable

Original Traceback (most recent call last):
  File "/usr/lib/python2.5/site-packages/django/template/debug.py",
line 71, in render_node
result = node.render(context)
  File "/usr/lib/python2.5/site-packages/django/template/
defaulttags.py", line 122, in render
values = list(values)
TypeError: 'int' object is not iterable

>>>

I think defaultdict have to work as normal dict.

Re: Is it possible to output JSON like this?

[Darthmahon]

Hi guys, I'll give both a try tomorrow when I am near my dev box
again. Can't really do it in the template as I just want to dump out
JSON only, but I'll give them both a go :)

Cheers,
Chris

Submit button names are not showing up in request.POST

[kesmit]

I have a form where I need to know which submit button is being
pressed in order to process the form.  The inputs below are the submit
buttons that I have.




I've simplified the view down to the following just to see what's
going on:

@login_required
def home(self, request, mode='stats'):
print request.POST

I'm getting the other form values in request.POST (which include an
input of type="text" and a select), just nothing for the submit
buttons.  I know this used to work, unfortunately I don't know when it
stopped.  I am using Django 1.0.

Re: Logout- Back Button

[jai_python]

But closing browser after logout in not a proper solution for this

accont and hit back button, it will prompt to login page, this is one
proper method for secure our data. Does django supports this
methodology ?

filtering in a template based on foreign key or query params

[Milan Andric]

Hello,

I have a view that displays hundreds of applications based on some filter
params.  But I want to render the actual template based on user (an fkey)
and list their applications as sub objects. but only the applications that
were filtered on. bleh.

So in the view I do something like:

# define queryset params from query string.
query_params = {
'status'   : request.GET.get('status', None),
'complete' : request.GET.get('complete', None),
'workshop__in' : request.GET.getlist('workshop__in'),
'user__is_active':True,
}
# form params need to be integers
query_params['workshop__in'] = [int(i) for i in
query_params['workshop__
in']]

# None or '' means don't filter on it.  Remove it so
# Foo.objects.filter() will give the correct results.
for key in query_params.keys():
if query_params[key] == None or query_params[key] == '':
del query_params[key]

# Pass query dict we just built as keyword args to filter().
queryset = Application.objects.filter(**query_params)

This gives me applications based on the query params that I iterate over in
my template.  The problem is I want to change the template now to display
based on the person/user foreign key and have the applications listed
underneath the person.  If I send a queryset of Users to the template then I
can get a list of users but I lose the applications filters.  Or is this a
good solution for some kind of querying filter/template tag?  If I send a
list of applications then  I can't list by user.

Any suggestions?

Thank you,

Milan

One Question About Cache

[Rodrigo Lopes]

Hi there,

I would like help with this problem. I'm studying some cache strategies for
my application, and I've got this doubt:

I would like to know if is possible to use *TWO caching systems together*:
memcached and filesystem caching

I want to use per-view cache with memcached and low-level cache with
filesystem caching.

How could I figure this out?

Regards

Did you follow the instructions in the Wing IDE documentation? You need
to use the --noreload option. It's very practical to debug Django under
Wing.

Select a list item by index

[jago]

I have a for loop over a list A.

inside the loop I want to print out the item of list B at the index
'forloop.counter0' of list A.

It is really strange. One can select randon items in a list, or the
first item in a list, but I did not find a way to select the list item
by index.

Am I missing something?

Re: Forms Question

[Robocop]

So i've just gotten back on this project, and it looks like i'm still
doing something wrong with my forms code.

What i have right now is:
def timesheets_add(request):
  if request.method == 'POST':
form = TimeSheetForm(request.POST)
if form.is_valid():
  form.save()
  return render_to_response("confirmation.html",locals())
   else:
  "some YOU FAILED" code
  else:
form = TimeSheetForm()
return render_to_response("form_page.html", locals())


The error i receive now is "TimeSheetForm has no attribute "save""

App initialized twice? plus, debugging tips.

[project2501]

Hi,
  I'm new to django and have a couple questions.

I have a __init__.py in my app and try to declare a simple module wide
variable. I noticed __init__.py is called twice when I run "python
manage.py runserver". Is this normal?

Also, I tried to run "manage.py runserver" through my Wing IDE in
debug mode, but it failed. Is there a convenient way to debug django
apps?

thank you!!

"Doubtful" is a little harsh. Contenttypes and GenericForeignKeys both
work fine, and there are extensive unit tests to demonstrate this.
They also work fine in the presence of fixtures, given certain
preconditions.

You are correct in saying that fixtures with ContentTypes can have
problems - these are well understood, and I have plans to address the
problems as part of a fix for ticket #7052. However, as long as your
test data is self contained - i.e., you're not relying on the
implicitly created ContentTypes - you should be fine.

However, this point is worth clarifying for Andy's benefit. Andy: Does
your test fixture contain the content type definitions? Since
ContentType is a dependency of your Calendar app (by virtue of the
Generic Key), the content types will need to be in the fixture. Is
this the case with your project?

Re: Confused about unittests and fixtures

[Alex Koshelev]

GenericForeignKey and content type application itself look very doubtful for
me. If you have a ForeignKey to the ContentType model then you depends on
order with ContentType objects creates on syncdb. Because ContentType that
references to some model can have different primary key any time you flush
database.

I've faced this issue than develop some application that has fixtures with
ContentType references. Reference brakes when needed ContentType object has
illegal primary key.

Assuming that FIXTURE_LIST is correctly defined and references well
formed fixtures, I can't see anything obviously wrong with your
example. You are correct in your understanding that a Django TestCase
will flush the database at the start of each test, so both tests
should have a clean database and be reporting the same results.

The suggestion that the GenericForeignKey is the source of the problem
is certainly plausible. I'm not aware of any problems serializing
Generic FK's, but they are more complicated and less exercised than
regular keys and fields, so it is certainly a reasonable place to
start looking.

If you could provide a minimal complete example of this behaviour and
attach it to a new ticket, it would be most helpful.

Getting non-related records

[John M]

i have a model at http://dpaste.com/88760/

for a particular Report (r), I'd like to get all categories that
aren't in it's bulletpoints.

For example, If there are four categories: one, two, three, four.
there is a report with bullet points for one and two, how can I get a
list of three and four.

This allows me to offer a user to add bulletpoints in those
categories.

I hope this makes sense :P

The version mismatch on shared library versions is indeed usually what
the problem is.

You need to run 'ldd' on all Apache modules, all PHP modules if using
PHP, and Python LDAP modules and work out which LDAP client libraries
they use.

Normally Apache mod_auth_ldap would use self contained LDAP client
implementation and so it shouldn't be an issue unless symbols not
being namespaced, but may be possible (not sure) to tell it to use
distinct LDAP client library as well.

See:

  
http://code.google.com/p/modwsgi/wiki/ApplicationIssues#MySQL_Shared_Library_Conflicts

This is about MySQL, but same sort of issue. See how 'ldd' command is
used in that case to check library versions and do similar thing for
LDAP stuff.

Re: Sort querysets by their data attribute values

[John M]

I had a similar need based on a calculated column, you'll have to turn
it into a list (i.e. mylist = list(queryset) ) and then sort from
there.  You can still pass the list to a template a loop through it
just like a regular queryset, since the objects in the list are just
python objects.

Unfortunately the function that each child will run is a bit more
complicated than just listing workers.
It involves output of different equations depending on the class.
Think of it like calculating rents for the different Places and the
rate of rent depends on both the size of the Place and the type of the
place (ie a charity shop might have a lower rate)

As I said, I have the function named the same in each child class but
I need to be able to access it from a list of all the Places.

My current thinking is just a long list of try, except: statements
attempting to call the subclass from the Place model but this feels
hacky and un-clean.

Alistair



Maybe something like this might work:

Store the content type of the child in the parent model.

class Place(models.Model):
 place_type = models.ForeignKey(ContentType)

 def get_workforce(self):
 child = self.place_type.model_class().objects.get 
(place_ptr=self.id)
 child.get_workforce()

I don't know what MyModelForm.get_queryset is intending to do here but
a ModelForm doesn't have such a method by default so you are not
really overriding anything in case that's what you are trying to do.
So "import pdb" is never getting executed by the Admin change list
because the Admin is not supposed to call get_queryset on the
ModelForm.

Re: Sort querysets by their data attribute values

There is no other way to do this in python/django layer. But you can try to
add your temp data in database layer and sort where.

Sort querysets by their data attribute values

[dexter]

I have a queryset which I have looped thru and added a (temporary)
data attribute to each instance. Now I would like to order the
queryset by the value of the data attributes. If I do it like this:

sorted(queryset, key=lambda x: x.data_attr)

the queryset turns into a list and I can't use it like a queryset
anymore = not good!
How can i solve this?

Re: Logout- Back Button

[Scott Moonen]

Hi,

This is why many secure web application (e.g., your bank or credit card
company) ask that you close your browser after you logout -- so that no one
else can get to any of your data that may be stored in the browser cache.

If your users are using your application from https:, then this is all you
have to worry about -- ask them to close their browser and the data will be
cleared (browsers should not persist https cached data after exit).  If your
users are using vanilla http, then you should ensure that your application
is sending the appropriate Cache-Control header to force the page not to be
cached.  In any case, you will still need to ask your users to close their
browser after logout.

Re: including javascript in templates

[Steve Holden]

You don't need to serve them from Apache for development - then it's OK
to use Django. It's only in production you want to use some other server
for media and static content.

I have this at the end of my settings.py just to keep my test sites
looking reasonable:

# Serve static content so test site looks reasonable
if settings.SERVE_STATIC:
urlpatterns += patterns('',
*tuple(
(r'^%s/(?P.*)$' % d, 'django.views.static.serve',
  {'document_root':
'/home/holdenwe/websites/test_holdenweb_com/static/%s' % d})
for d in settings.STATIC_DIRS ))

Thanks for pointing me in the right direction, the only thing I needed

Karen,

thanks for the info. However, i don't use any translations.
I do have USE_I18N = True but changing it to False doesn't change a
thing so the issue remains.

The bug report you mentioned is already 2 years old and it's isn't clear
if this is a bug or not although it does seem like a bug to me and quite
an annoying one if you're using another date format.

I can manage by using the date tag in templates and always converting
the dates in my views but one would think the settings would be there to
handle this kind of things.

Is there a way to define the date format globally or convert it
globally? That would also help.

Regards,
Benedict

Filtering the modelform in Admin on request.user

[shabda]

I have an Admin site which I want to filter based on request.user.

My ModelAdmin class is something like this,

class FilterOnUser(admin.ModelAdmin):
def queryset(self, request):
return self.model._default_manager.filter(user = request.user)

def get_form(self, request, obj=None, **kwargs):
form_class = super(FilterOnUser, self).get_form(self, request,
**kwargs)
class MyModelForm(form_class):
def get_queryset(self):
import pdb
pdb.set_trace()
return super(MyModelForm,
self).get_queryset().filter(board = request.board)
 return MyModelForm

So when I navigate to the change view on my admin site the
pdb.set_trace is not hit. What am I doing wrong?

date formats in settings.py

[Benedict Verheyen]

Hi,

i have a question on the different date/time settings one can specify in
 the settings.py.
I currently have these:
TIME_ZONE = 'Europe/Brussels'
DATE_FORMAT = 'd/m/Y'
DATETIME_FORMAT = 'd/m/Y H:i'
TIME_FORMAT = 'H:i'
YEAR_MONTH_FORMAT = 'm Y'
MONTH_DAY_FORMAT = 'd m'

However, any date i enter in the admin section is displayed as Y-m-d.
I thought these settings would adjust the way dates are displayed but it
doesn't seem so.
What is the purpose of these settings?

Benedict

Re: including javascript in templates

Hi Håkan,

yes, I missed the reading of that link. Now that I have set up
correctly it works fine.

But it has a BIG disclaimer, and the reccommendation is to let the
webserver to serve these files (that is what I really want)
http://docs.djangoproject.com/en/dev/howto/deployment/modpython/#serving-media-files

So, I should configure my own development Apache to serve them. (We
will probably have only one webserver in the production environment,
although separated webserver are recommended).

Thanks a lot!

Re: Template inheritance

[Alaric Haag]

Belated thanks for that; the "specialization" tip helps. It feels a 
little like I haven't flopped over to the correct way of thinking about 
it.

Custom tags and inclusion tags are helping me sort it out a bit though.

including javascript in templates

[David Sáez]

Hi, I'm a newbie to django and I'm dealing with some configuration
stuff that is making me going crazy. My problem is very simple and I
have a temporal solution, but I guess there might be a better way to
do it. So... there goes the question...

¿ How do I include javascript in a basic template ? I mean, imagine
this template:






Hello {{ user_name }}



The javscript inclusion does not work, altough I have configured these
settings:

MEDIA_ROOT = /an/absolute/file/system/path/'
MEDIA_URL = '/m/'

It is not defined in urls.py, and I suppose that I will have this
problem when including CSS and some other media, such as images, flex,
etc...

Does anybody know the right solution?

Thanks in advance :)

Searching over the documentation with terms like "automatically
escaping" or "autoescaping"
gives this

http://docs.djangoproject.com/en/dev/topics/templates/

as the first hit. Unsurprisingly, one of the sections in that document
is "Automatic HTML escaping"

Try reading it to know how you can control the feature.

Re: Newbie question: HTML formatting not applied to pages

[Jeff Beckham]

Sure.

Here's /blog/models.py
http://dpaste.com/89108/

/blog/urls.py
http://dpaste.com/89109/

I've got nothing in /blog/views.py right now.

As far as templates, this is /templates/base.html (it's got the
autoescape tags included)
http://dpaste.com/89112/

/templates/blog/list.html has only one line:
{% extends 'base.html' %}

and nothing at all in /templates/blog/detail.html

Thanks!

don't escape html tags

[gontran]

hello,

I just started to learn django, so my question may be stupid:

In my template, I would like to display a html string (stored in my
database). My problem is that it displays the string but it
automatically escapes the html tags.

for example, if my string is: my text
 instade of showing: my text
 it shows: my text

any idea to fix that?

thanks for your help

Django doesn't use LONG columns.  Please make sure that you're using
Django 1.0+ and *not* a 0.96 release.  The oracle backend included in
0.96 was incomplete and should not be used.

Hope that helps,

Re: model inheritance - getting data from child objects

Unfortunately the function that each child will run is a bit more
complicated than just listing workers.
It involves output of different equations depending on the class.
Think of it like calculating rents for the different Places and the
rate of rent depends on both the size of the Place and the type of the
place (ie a charity shop might have a lower rate)

As I said, I have the function named the same in each child class but
I need to be able to access it from a list of all the Places.

My current thinking is just a long list of try, except: statements
attempting to call the subclass from the Place model but this feels
hacky and un-clean.

Confused about unittests and fixtures

[AndyH]

Hello,

I have the following simple test which demonstrates the confusing
behaviour I'm seeing:

class AvailabilityTestCase(django.test.TestCase):
fixtures = FIXTURE_LIST
def setUp(self):
response = self.client.login(username='testuser',
password='password')
self.assertTrue(response)

def test_page(self):
print Calendar.objects.all()
print Calendar.objects.all()

def test_page_again(self):
print Calendar.objects.all()
print Calendar.objects.all()

When I run this from "manage.py test", it prints out four lists of
Calendars as expected. However, the second two, are slightly different
to the first two. As far as I'm aware I'm not doing anything to the
all() method (or subscribing in to any triggers) that might cause
this. But even if I was, my understanding is that the fixtures are
refreshed for each test so they can run independently of each other.
In my case, which ever order I run these two tests the second set
always prints different results to the first.

The only clue I have to go on (as this doesn't happen with the Auth or
Group models) is that the Calendar model has a GenericForeignKey
field, and it is this field which seems to be different in the second
two Calendar lists (even though the content_type, and object_id are
correct).

Incidentally, if I add a third and fourth test, they also show the
incorrect list. And obviously, the behaviour isn't seen if I refresh a
list of Calendar objects in the admin, or run the code in the
interactive shell.

Any thoughts on what I'm missing.
Thanks for taking the time.

Andy.

Apache Segmentation Fault on succesful authentication

[huw_at1]

Hi all. I am having some real problems with this. I have an LDAP
authentication backend that I have hooked up to my app. Standalone it
appears to run fine. However when running it through my apache server
I am seeing alot of segmentation faults in my error log coupled with
the redirection page not loading on succesful authentication.

I have googled around a bit and seen a few other threads with LDAP
authentication and apache segementation faults. However none of them
seem to be quite the same issue that I am experiencing. The only thing
I have managed to garner thus far is that there may be a version
mismatch betweem the openldap libraries used to compile apache with
and those used to compile the python-ldap module.

If anyone has any ideas about this or, miraculously, has a solution I
would be most grateful.

Having trouble with django-multilingual

[Brandon Taylor]

Hi Everyone,

I'm having a hard time getting django-multilingual to work the way I
expect.

#settings.py

LANGUAGES = (
('en', 'English'),
('es', 'Spanish'),
)

TEMPLATE_CONTEXT_PROCESSORS = (
...
'multilingual.context_processors.multilingual',
)

MIDDLEWARE_CLASSES = (
..
'multilingual.middleware.DefaultLanguageMiddleware',
)

#models.py

from django.db import models
from django.contrib import admin
import multilingual


class Widget(models.Model):
name = models.CharField(max_length=50)

class Translation(multilingual.Translation):
name = models.CharField(max_length=50)

class Meta:
verbose_name = _('Widget')
verbose_name_plural = _('Widgets')

def __unicode__(self):
return self.name

#index.html

{% for widget in widgets %}

{{ widget.name }}

{% endfor %}


When I switch my locale in FireFox, widget.name is always English.
What am I doing wrong? I'm trying to follow the documentation as
closely as possible, but obviously I'm missing something.

Advice appreciated,
Brandon

Wouldn't it be possible to put the configuration in a .htaccess file,
given that AllowOverride is set?

If I put the settings that would normally go into a location directive
directly into .htaccess, everythings seems to work just fine. 

This might be slower, is there anything else to be said against this
solution?

Re: Using Django

[Blu3ness]

Hey there,

I am running Django testing server on Dreamhost as well, and I can
tell you it works fine. So I am sure you are probably just
misconfiguring something.

Like AndyB said, .htaccess needs to pass the URL to your dispatch.fcgi
on the dreamhost server, all of your django projects and folders needs
to be in the PYTHON path, not actually under the public viewable
domain directory. Take my directory structure for example.

/home/USER/
  -  local/lib/django   - django main project files
  -  django_projects  - my application code
  -  django_templates - my django templates
  -  beta.mysite.com  - actual public viewable area serving static
files

Hope that helps.

Good luck,
Blu3ness

You may want to try out a deployment option other than
Apache/mod_python, then, but I'm honestly a bit curious how you're
planning to use mod_python at all if you don't have access to the
Apache configuration file.

Re: model inheritance - getting data from child objects

[Thomas Guettler]

I have never used model inheritance, but I read the documentation

If all worker classes (cook, waiter, ...) are subclassed from Worker,
something like this should work: Worker.objects.filter(workplace=...)

(Given that workers only work for one workplace)

Re: Help regarding Sqlite3

[sergioh]

Also you can use the python shell, you can import your models and
create objects, the you can save them and also make queries to your
model.

is simple as:

# manage.py shell
>>> from django.contrib.auth.models import User
>>>User.objects.all()
..

Also the structure of the tables created you can obtain with the
following command:

manage.py sql [model]

this command will show you the sql used to create your tables.

Try JQuery. If your input box has an id "blah" then:
$('#blah').val("some new value") 
would set it for you.

jQuery is very cool for this kind of thing.

It's a functionality that isn't currently included in Django. See:

http://docs.djangoproject.com/en/dev/faq/models/#if-i-make-changes-to-a-model-how-do-i-update-the-database

There are some external projects that offer provide schema evoluton
functionality:

south, dmigrations, django-evolution, dbmigrations, deseb,
django-schemaevolution

Google for them.

Since you've already created the tables, you'll need to modify them
manually in the database to add the server_id column - or just drop
the tables and re-run 'manage.py syncdb'.

This is totally unrelated to Django and ModelForms. javascript runs on
the browser, *after* the whole page containing the form has been sent
by the server. IOW, at this stage, all you have is a plain old HTML
form. For questions related to client-side HTML form (or whatever)
scripting, please post on comp.lang.javascript (and possibly, learns a
bit of javascript before...).

I cannot remember doing anything extra.  My understanding is that
Python can find any module in the site-packages directory, so if you
have:

C:\Python25\Lib\site-packages\MySQLdb
 it should work

When you run the installer, it finds your Python version in the
registry, and installs MySQLdb into that.  So one possibility is that
maybe you have 2 Python versions, and installed MySQLdb into the other
version (which you are not using for django).
I also have C:\Python25 in my system path - that is anyway useful to
have.

syncdb problem with standalone applications

it as installed applications in the project settings. But everytime i

syncdb command to the project, all the standalone application related
database schema won't be updated. I must remove the whole .db file and
create it with command sqlall again, than i get the reflection of the
changed i've made.

Is this a feature or a bug? Or is there another tricky ways to get the
syncdb command to work? Please help me, i can't remove and then create
the whole database schema everytime i make a change to models. Any
suggestions would be appreciated.

I've got the same package but I'm getting the same error.
Is there anything do once you run the exe ? Did you make any special
configuration in your Windows (I'm on XP SP2) i.e. PATH etc...
Thanks

Thanks - should have added that I have already tried that, but if I do
I get:
OperationalError: (1054, "Unknown column 'backup.server_id' in 'field
list'")
I get this not only in my view, but also in the 'Backup' part of the
Admin.  I guess I should stick with the ForeignKey, and try to solve
the Unknown column - problem.

Did you originally have it working without either blank or null? Don't
forget that Django won't change any existing database tables. You'll
need to drop the tables and re-run syncdb if you make changes to the
model.

Well, you don't appear to have any foreign keys linking Backup and
Server. You'd need something like this in your Backup declaration:

server = models.ForeignKey('Server')

multi foreign keys and ordering in admin

[MikeKJ]

Got something like this

class A(models.Model):
x
class Admin:
x

class B(models.Model):
a =models.ForeignKey(A)
xxx

class C(models.Model):
a = models.ForeignKey(A)
x

classD(models.Model):
a=models.ForeignKey(A)
xx


how do I control the ordering of B,C and D please. At the moment it
appears to be random neither in alpha or in order of the classes.

Don't know, but consider this:

app_a/models.py:

from app_b import ModelB
class ModelA(models.Model):
name = models.CharField(max_length=10)

class ModelC(models.Model):
name = models.CharField(max_length=10)
model_b = models.ForeignKey(ModelB)

app_b/models.py:

from app_a import ModelA
class ModelB(models.Model):
name = models.CharField(max_length=10)
model_a = models.ForeignKey(ModelA)


Result: Cannot import ModelA.
There are various ways round this, but the easiest is just to drop the
imports and use the string format:
models.ForeignKey('app_b.ModelB')

a) If your form is the same as your Model, why not use a model form? [1]

b) if you want to allow foo to be null, add 'null=True' to the foo field in
the model [2]

The login view in the Django admin actually used to do this; see our
most recent security-oriented release for the reasons why it doesn't
do that anymore...
