Not yet. Honza Kral's Google Summer of Code project for model
validation is due to be merged reasonably soon though, so this will be
in version 1.2 - or in trunk at some earlier point if you don't want
to wait that long.

'Project' is a bit of an artificial concept. The only thing a Django
site really needs is a settings.py. So you can have two of these, with
separate Apache vhosts or whatever, but with both referring to the
same models files - as long as those models are on the Python path.

Re: views help with category_list for a blgo

Well, currently you're relying on the extra_context parameter to your
generic views to pass in the category list. However, as you've noted,
this doesn't work for pages like search which aren't generated by
generic views.

So take the category_list stuff out of urls.py completely. Instead,
use an inclusion tag. This could be as simple as:

@register.inclusion_tag('_category_list.html')
def category_list():
return {'category_list':Category.objects.all()}

Now, take the template code that displays the list out of your base
template, and put it into a new file called _category_list.html. Back
in the base template, put:
 {% load mytemplatetags %}{% category_list %}

(replace 'mytemplatetags' with whatever you've called the template tag
file you created). All done.

Separate a project into 2 - both need to access the same models

[Merrick]

I have a project that I am thinking of breaking up into 2 sites/
projects. The goal is to be able to make changes to one site/project
without affecting the other one. Here is an example of what each would
do:

mydomain.com
-
- displays the brochure website (sales copy on the homepage, about,
privacy etc...) (Page Model)
- tracks visitors as they move around from one Page to another (Access
Model)

dashboard.mydomain.com

- users can login
- user can click on a Page and see how many times it was Accessed
(Page and Access model)

So I am operating under the assumption that I will have a total of 2
settings files, one for each site/project. I am guessing that I need
to define the models Page and Access model on each project. Is this
correct? Is there an optimal way of splitting things up to keep up
time up, but avoiding repeating model definitions?

Thanks.

How to get cms like features in Django

[ristretto.rb]

Hello All,

I have pages like home, contact us, about us, that are on nearly every
webapp that I create.  The other parts of the webapps are specific to
some business requirement, but the *us type pages are not.  Unlike the
application pages proper, this supporting pages need to be updated
occasionally when the system is Live, and by non-programmers.

I could use a CMS, and then have links to my app on the pages.  But, I
don't want to run a full blown CMS and Python/Django.  And getting the
templates working in both seem like extra work.

I have searched a bit, and haven't found support for this.  So I
thought I would roll my own (see below.)  Does anyone else have this
need?  How do you solve it?

class CMSPage
page_data = 
page = 

urls.py
   (r'^about/$', 'about'),

views.py
   def about(request):
 page = CMSPages.objects.get(page='about')

 return render_to_response('cms_page.html', {'page':page},
context_instance=RequestContext(request) )


cms_page.html
:
{{page.page_data}}


Then I can let the user edit the CMSPage via the admin.  And, perhaps
I could even get TinyMCE or DOJO Editor going for them them.

I just want to check there isn't support for this sort of thing,
before I run of doing something custom.

thanks
Gene

Formwizard dropdown lists

[dingue fever]

Hi,

I have modelform that I use in a formwizard and I populate a few of
the dropdown selects by accessing the database and creating a list for
the choice. However when I add an item to a table via the admin site
and then goto my formwizard page the new item does not show up in the
list until I recycle the server (djangos or apache).

I know that the database is being hit when the form is accessed
because I print the list to the log file when the form is called and
the new item is listed. The new item is also listed in standard
modelform, not using the formwizard.

Has anyone seen this type of thing before.

Regards
Dingue

Re: F() expression order of operations

[Stefan Petrea]

What are F() expressions and where are they documented ? (just didn't
hear the term until now)

About your win_percentage column , wouldn't you rather have it as a
method which is being
calculated from the columns wins and losses instead of a column stored
inside the table ?

F() expression order of operations

[Brent Hagany]

I'm having some trouble getting F() expressions to obey my parentheses
when I don't want the default order of operations.  For example, given
the model:

class MyModel(models.Model):
wins = models.DecimalField(max_digits=1, decimal_places=0)
losses = models.DecimalField(max_digits=1, decimal_places=0)
win_percentage = models.DecimalField(max_digits=4,
decimal_places=3, default=Decimal('0.000'))

I get the following results when trying to calculate the
win_percentage:

In [1]: MyModel.objects.create(wins=2, losses=4)
Out[1]: 

In [2]: MyModel.objects.all().update(win_percentage=F('wins') / (F
('wins') + F('losses')))
Out[2]: 1

# I expect this to return Decimal("0.333")
In [3]: MyModel.objects.get(pk=1).win_percentage
Out[3]: Decimal("5.000")

It appears to be ignoring the parentheses around F('wins') + F
('losses'), and so instead of 2 / (2 + 4) = .333, I'm getting 2 / 2 +
4 = 5.  Am I doing this wrong, or is this by design, or is it a bug?

Re: Getting fields in a user profile

Hi,

filter returns a list, with zero or more elements. To fix what you showed,
you should call "get" instead of "filter". "get" either return a object or
throws an Exception. Check the docs for more info.

Getting fields in a user profile

[PlanetUnknown]

Hello All,
I recently extended my User, with a User profile called
GenericUserProfile, and it has a many-to-many field called farms (code
below). Now all I want to do was add a "farm" to this farms field in
the GenericUserProfile.

But when I try doing that using the django python shell I get error -
"AttributeError: 'QuerySet' object has no attribute 'get_profile'".

   I'd really appreciate if someone could point out what I'm doing
incorrectly and what is the correct approach. The documentation says
that get_profile() is created when the profile is present and I
checked the database and it shows an entry in "genericuserprofile"
table corresponding to the "user" who is registered.

Code -

# The User profile which extends fields for User
class GenericUserProfile(models.Model):
user = models.ForeignKey(User)
#other fields here
farms = models.ManyToManyField(Farm)
confirmation_code = models.CharField(max_length=200, unique=True)
is_active = models.BooleanField()
create_dt = models.DateTimeField(auto_now_add=True)
modify_dt = models.DateTimeField(auto_now_add=True)

def __str__(self):
return "%s's profile" % self.user

def create_user_profile(sender, instance, created, **kwargs):
if created:
profile,created = GenericUserProfile.objects.get_or_create
(user=instance)

post_save.connect(create_user_profile, sender=User)


# The Farm model, A user can have many farms, and farms can have many
owners, hence many-to-many
class Farm(models.Model):
farm_id = models.AutoField(primary_key=True)
is_owner = models.BooleanField()

 I try this in the django python shell, I want to add the farm to
the "farms" field in GenericUserProfile. Hence trying to get the
profile first.
>>> f1 = Farm(farm_id=None, is_owner=True)
>>> f1.save()
>>> c1 = User.objects.filter(email__iexact="x...@xyz.com")
>>> c1.get_profile
Traceback (most recent call last):
  File "", line 1, in

Re: Test tables not all created

[peppergrower]

By "normal database" I meant the one that gets used normally by
Django, e.g., while running the development server (manage.py
runserver)--in contrast to the test database.

Thanks for the pointer.  I checked my INSTALLED_APPS, and somehow I'd
missed a module.  I'm not sure how that happened, since the
appropriate tables did exist in my normal database, and I don't have
any idea why I would have removed the appropriate line after I already
had it set up properly.

Adding back in the missing module, the test worked as expected (and
all necessary tables are created).  Thanks for the help!

Re: Mutually exclusive fields in model validation

[J. Cliff Dyer]

Override the save method on your model, something like:

class MyModel(models.Model):
field1 = models.TextField(blank=True)
field2 = models.TextField(blank=True)

def save(self):
if (self.field1 and self.field2):
raise ModelValidationError, "only one can live"
elif (not self.field1 and not self.field2):
raise ModelValidationError, "one must live"
else:
super(MyModel, self).save()

Untested code.  I don't remember if ModelValidationError exists, and I
don't know if you need to tweak the signature on your save method, but
that should get you pointed in the right direction.

Cheers,
Cliff

Mutually exclusive fields in model validation

Hi all,

I have a model wherein I want to put a validation as
You must enter Field1 or Field2, but not both.

This model is at the back end and not visible through forms.
How do I accomplish it?

Fair enough. I suspect this is one of those times when you've gone
beyond what the ORM can do for you, and you need to drop back to SQL.
Luckily this is easy to do:

from django.db import connection
cursor = connection.cursor()
cursor.execute("""SELECT S.value, D.value from data as S left join
data as D on
S.entry_id=D.entry_id;""")
for row in cursor.fetchall():
   # do something with row

Re: path depth problem

[Tiago Serafim]

Hi,

The right way(TM) to do this is using named urls:

http://docs.djangoproject.com/en/dev/topics/http/urls/#named-groups

Then you can use reverse to get the right url, avoiding duplications and
problems like the one you have now:

http://docs.djangoproject.com/en/dev/topics/http/urls/#django.core.urlresolvers.reverse

Re: psycopyg setup error: no build_ext

[nausikaa]

Dear Matt

I hope you see this message even though it's probably too late.
To fix the permission denied error change setup.cfg as follows:


pg_config=/opt/local/lib/postgresql84/bin/


needs to be changed to


pg_config=/opt/local/lib/postgresql84/bin/pg_config


Then run sudo python setup.py build again and it'll just work fine.
Hope you didn't fiddle around with sqlplus or anything.

Re: psycopyg setup error: no build_ext

[nausikaa]

Dear Matt

I assume you used mac ports to install postgresql-devel.
Now the reason for the permission denied error is that
you didn't specify the file in setup.cfg. To make it run change the
line

pg_config=/opt/local/lib/postgresql84/bin/


to

pg_config=/opt/local/lib/postgresql84/bin/pg_config

in setup.cfg.


If this does not sort out the problem try

sudo port install postgresql84

Then all should work just fine. postgresql-devel is outdated.

Hope this helps,

Nausikaa

path depth problem

[dijxtra]

Hello everybody,

Django keeps surprising me with neat solutions for common web
programming problems (I must say I haven't felt this "where has it
been all of my life" since the time I was exploring lisp), so I hope
django has a trick up his sleeve for this one too.

So, I made a calendar "widget" (view snippet: http://pastebin.com/m765f778c,
template snippet: http://pastebin.com/m16dcf115) and I have a problem
with relative links in it. If I include this code in page with URL url/
prefix//mm/dd (which represents one day), then my links point to
right places, but if I'm in url/prefix//mm (which represents the
whole month) then links point to the wrong place because they are
relative links, and they were made to work with //mm/dd, not //
mm.

I tried to fix it with my {{calendar_data.path}} variable, but that's
one ugly solution. I suppose this is a common problem... so, I suppose
there is a common solution?

BTW, if you give me constructive advice about my coding style, you get
bonus points for heaven and I love you till the end of my life. :-D

def clean(self):

# These fields are no longer valid. Remove them from the

del cleaned_data["tipo_de_visa"]
del cleaned_data["empresa"]

return cleaned_data


with the above code I am trying to validate if the user selects
business then you must place the name of the company.

It does not work, someone can help me.

Re: Running Django on Tornado's HTTP server

[Brian]

Thanks ... this link pointed me in the right direction.

Should I be able to serve up admin media using just Django and
Tornado?  If so, I haven't found the right combination of paths / urls
etc. in settings.py to get that working. The Tornado doc describes how
to "serve static files from Tornado by specifying the static_path
setting in your application" - so it sounds like it might eventually
work? The Tornado blog demo is one example, but I couldn't get that
approach working with my Django app.

I now have nginx serving up the Admin files, running alongside Tornado
and Django. My Admin Site formatting and layout looks fine with that
setup.

Thanks DR.

I do have the list on the base right now, but I don't think I have it
correctly assigned as a custom tag.  I didn't think of that, I'll
check into it.  Thanks!

Re: How to organize django projects on a productive server?

[orschiro]

Hello Andrew,

thanks for that detailed reply. :)

So the key for development and deployment is a VCS such as SVN or Git?

In short: Your developers are pushing the changes up to the branches
on the stating server where a release is going to be created. Then it
is going to be transfered to the production server. right?

One thing I still concern about. How do you manage the production
database when a application change is going to be made?

For example you changed some models. To apply that changes on the
development server you might just reset the database or alter it
manually - it's indeed only for testing purposes - but what's with a
"real" database with tons of important data?

Hello Daniel,

so the projects could be as well on the users home path?

It makes more sense for me to put them on the home path than anywhere
else.

Things like category lists on every page are exactly what custom
template tags are for. You could include your tag on every template,
or even better on the base template that other templates inherit from,
and it will then definitely appear on every page.

Re: How to organize django projects on a productive server?

[Léon Dignòn]

The reason is that I use Debian and /var/www is just Debian's default
folder (and herewith apache's). You can basically put your code
wherever you like. But you shouldn't put your code beneath apache's
document root (document_root is a setting in the apache.conf). My
docroots are configured individually at in the virtual host config: /
var/www/site1,site2,…. So /var/www/django is save!

You can use the form parameter to formset_factory to pass in a
customised Form subclass that includes your overwritten __init__
method.

It's a very bad idea to put your Django code under /var/www. That's
the default root for Apache, so your code files might end up being
served out to users - allowing them to see implementation details and
even database passwords.

Django and your project code don't need to live under the Apache root,
it should just be somewhere on the Python path.

Hello Léon Dignòn,

you told that your projects lie beneath /var/www..

So the reason for that is that you might use Apache?

As I remember (I'm using nginx instead of Apache) this is the default
directory.

Re: How to organize django projects on a productive server?

[Andrew McGregor]

You've asked a lot!  I'll start with this question:

> And final, are you developing on your local machine with the
> development server or immedeatly at the server via ssh?

Loads of different ways, but I do this:

* Production server - dedicated Debian host

* Staging server - hosted Debian VM

* Development boxes - each developer has one or more VMWare Debian instances

> If yes, how do you deploy your project and about what points do you
> have to concern while doing that?

As a rule of thumb you only commit code changes from dev boxes to
branches, or a tagged release if necessary. Staging should only svn
up, and production has it's own release script.

When tested these can be merged to trunk.

Trunk can be released to staging for UAT.

If UAT OK then press the button for the release script to send it to production.

This release to live can get complicated to mitigate all issues.  You
need a way to get the latest codebase live whilst minimising downtime.
 You could svn co to a new dir on the same filesystem, then `mv $CUR
$OLD && mv $NEW $CUR` should be atomic, but the svn co could take time
on large systems and eat bandwidth.  If you are using SVN you may be
interested in file permissions. More thank likely you have schema
changes in which case you may accept that downtime is given then you
will need some sort of maintenance mode.

Of course, extra browny points for a wrapper around svn/git/whatever
so that on attempting a commit unit tests are run and a bunch of other
sanity checks.  If OK then the commit works.

Spend a fiver on Agile Python Development.

My Django projects lie beneath /var/www/django/
Templates and media files are in /var/www/django/myproject/
templates,media (the comma means that there are two separate folders)

Before that I had a folder called /var/www/django/templates,media/
myproject
But because I moved them often I changed to a centralized project

As soon as your website is published you should use a dev server to
test your new code. So problems are not published to your visitors.

How to organize django projects on a productive server?

[orschiro]

Hello guys,

first, I know it is not that important how to do this but as I'm
pretty knew and callow I'd like to know how some experienced users do
that.

At the moment I have just a normal user account besides my root that
stores all my django projects. Also my django trunk lives in there.

Another point what interests me. Are you using a central directory for
static files and templates etc. that are available for all your
projects or does every project have its own directories in there?

And final, are you developing on your local machine with the
development server or immedeatly at the server via ssh?

If yes, how do you deploy your project and about what points do you
have to concern while doing that?

Anyway, is there any good documentation how good deployment on a
server might look like?

I know, a bunch of questions but answers would be very helpful for
me.

Thank you guys. :)

Re: Can't get development server to run

[ChrisR]

What OS are you using?  Django may not be on your PYTHONPATH.

If you cd into your project's root directory (the one with
settings.py), type 'python' at the command line to start the python
shell.  Then try 'import django'.  You're probably going to see an
error saying it can't find that module.

Can't get development server to run

[GloWyrm]

I am following the tutorial, and I was able to create the mysite
directory, but I can't get the development server to work. When I run
"python manage.py runserver" from mysite I get this error...

Traceback :
  File "manage.py", line 2, in ?

Authentication with two or more sites under mod_python

[Lester]

Hello - I have a fedora 11, django 1.02, Apache 2.2, mod_python set
up.  I am using the standard Django modules and authentication system.

I am running two django sites on the same server - my main site and a
'beta'.

For some reason I can authenticate onto my main site fine, however
when I try to log onto the beta site I get redirected to the main
site, and am not logged in.  However I do not get any python errors.
I also have no problems if I switch the sites over (they are
essentially identical) or run the beta site from the command line.

Is there something I could have in mod_python/apache set up that could
be interfering with my authentication?  My python.conf is shown below:

LoadModule python_module modules/mod_python.so


SetHandler python-program
PythonHandler myvirtualdjango
SetEnv DJANGO_SETTINGS_MODULE technology.settings
SetEnv PYTHON_EGG_CACHE /var/www/django/technology/egg_temp
PythonDebug Off
PythonInterpreter portal
PythonPath "['/var/www/django/'] + sys.path"
#PythonOption django.root "/portal"



SetHandler python-program
PythonHandler myvirtualdjango
SetEnv DJANGO_SETTINGS_MODULE technology.settings
SetEnv PYTHON_EGG_CACHE /var/www/django-dev/technology/egg_temp
PythonInterpreter beta
PythonDebug On
PythonPath "['/var/www/django-dev/'] + sys.path"
PythonOption django.root /beta




SetHandler None


Does anyone have two or more authentic'able django apps running under
mod_python on the same server, so I at least know that the problem is
buried in my code somewhere?

i18n not always working

[Gabriel .]

Hi,

I have some batch process that send i18n mails, I'm using a template
to render the message body.
The subject is translated but not the body.

This is a sample code:

from django.utils import translation
from django.utils.translation import ugettext as _

lang = user.get_profile().language
if lang:
language = translation.to_locale(lang)
translation.activate(language)

subject = _("A translated subject")
message = render_to_string('updater/queuestatus.mail')

Any idea why?

Select models based on m2m relationship.

[Léon Dignòn]

Hello,

I have a m2m relationship like this:

class Actor(models.Model):
name = models.CharField(unique=True)
class Movie(models.Model):
name = models.CharField(unique=True)
actors = models.ManyToManyField(Actor)
class Comment(models.Model):
actor = models.ForeignKey(Actor)
movie = models.ForeignKey(Movie)
comment = models.CharField()

Every actor belongs to a number movies, every movie contains a number
of actors.

What I want to achieve is, that in the form I chose a movie from the
movie-dropdown list, then the actor-dropdown displays only actors
acting in that particular movie. This can happen with javascript,
ajax, or any other good stuff.

I don't know wheter to use javascript, or ajax, or whatever. I don't
know if my model is good. Please help me starting with this. It's a
little complex at the moment :)

passing parameters to formset

[Michael Stevens]

Hi.

I'm creating a formset of forms using formset_factory.

It's all working nicely, but I'd like to pass some values into the
forms to use as the choices for one of the fields.

Is there a way to do this? As far as I can tell the formset_factory
takes over the creation of the form and I can't see a way to pass my
own data in.

Re: how to return ajax info in one case, and redirect to a different url in another?

[Margie]

Yes, that was going to be my fallback if I couldn't get the server
validation to work.  I just find it so much more maintainable to do
the validation in python/django.  Anyway, did finally get it working,
thanks!

Re: how to return ajax info in one case, and redirect to a different url in another?

[Margie]

Thanks for the pointers!  I finally got it to work.  I had been doing
similar to your suggestion (returning ajax response like
["redirect_to": "http://www.example.com";], but I had been having
issues with setting the location and wasn't sure if that was the right
thing to be doing.  For some reason when I had a url that had a /
before an anchor, ie http://www.example.com/#comment_32, it wasn't
redirecting correctly and that was throwing me off.  Maybe that's not
even legal and just happens to work when I type it in.  Anyway, once I
got rid of the '/' before the anchor (www.example.com#comment_32) and
used

  document.location = url

that did the trick.  Thanks very much for your comments, that was a
big help.

views help with category_list for a blgo

[ChrisR]

Hello,

I am building a blog/cms for my site.  I am using django's date_based
urls as well as object_detail for the individual posts.

On my base, I have a for loop for categories in the blog.  I don't
like the way I have made the category_list work, and feel that it is
not the best way to do it.  I would like some help with that if
someone is willing to make suggestions.

The category list appears on all pages within my blog, but when I do a
search in the blog, the list disappears.

Here are my views:

from django.shortcuts import render_to_response, get_object_or_404
from django.db.models import Q
from blog.models import Category, Entry

def category(request, slug):
category_list = Category.objects.all()
category = get_object_or_404(Category, slug=slug)
entry_list = Entry.objects.filter(category=category)
return render_to_response("blog/entry_list.html", locals())

def search(request):
if 'q' in request.GET:
term = request.GET['q']
entry_list = Entry.objects.filter(Q(title__contains=term) | Q
(html_content__contains=term))
heading = "Search results"
return render_to_response("blog/entry_list.html", locals())


Here are my urls:

from django.conf.urls.defaults import *
from blog.models import Entry, Category

info_dict = {
'queryset' : Entry.objects.all(),
'date_field': 'created',
'template_object_name': 'entry',
"extra_context" : {"category_list" : Category.objects.all()}
}

urlpatterns = patterns('django.views.generic.date_based',
url(r'^(?P\d{4})/(?P\d{1,2})/(?P\w{1,2})/(?P[-
\w]+)/$', 'object_detail', dict(info_dict, month_format='%m',
slug_field='slug')),
url(r'^(?P\d{4})/(?P\d{1,2})/(?P\w{1,2})/$',
'archive_day', dict(info_dict, month_format='%m')),
url(r'^(?P\d{4})/(?P\d{1,2})/$', 'archive_month', dict
(info_dict, month_format='%m')),
url(r'^(?P\d{4})/$', 'archive_year', info_dict),
url(r'^$', 'archive_index', info_dict),
)

urlpatterns += patterns('blog.views',
url(r'^category/(?P[-\w]+)/$', 'category', name="blog-
category"),
url(r'^search/$', 'search', name="blog-search"),
)





If I need to provide more information let me know.  Thanks in advance!

Chris

Seeking contributors for TODO list project written in Python/Django/jQuery ( open source )

[Stefan Petrea]

Hello,

My name is Stefan Petrea and I'm working on a project built
using Django.
Basically the idea, is that of many wishlist-type of sites out there
(of which a representative site is tadalist.com).
What you can do is make lists of items , make items , edit them ,
re-order them(using jQuery) , delete items and list.
Attach Geographic positions to items with particular labels that
show up un a Google MAP.
You also have deadlines for all the items.

The project is sitting here at the moment
http://perlhobby.googlecode.com/svn/trunk/todolist_project/
But I plan to move it to either a separate a googlecode account or
a maybe github.

I'm planning to add some more things but I'd also like your input.
I've made a presentation for this also , it's here
http://www.youtube.com/watch?v=fHBuU2jc5Lw (I wanted to make it
shorter but oh well , it shows the main ideas).

I would like to add the following:
- add caching of links that may sit inside items
- add file upload/storage on server side
- reminders for the deadlines of the items
- whatever features you may like

The project is really open to contributors.
If you
- have a patch I will merge it into the code
- want to write some docs for the project you are welcome to do so
- can optimize the existent jQuery code that is welcome also
- know of any way that I can load up the whole Google Map upon
pressing
the Location div and not inside the onload event of  you are
welcome to send a patch
- want to help by optimizing the current code that makes queries on
the
database you are welcome
- want to sponsor the project or tune it to your needs you can contact
me

As an advantage that you have with this project over other Open Source
projects is that this has a relatively small code-base that you can
easily
understand and that I'm willing to document it properly so that it
will be
easy for someone to come in and make his/her own additions.

For any information on the project please contact me at this e-mail
address.

Best regards,
Stefan

Or.. you could just use django-dbtemplates[0].

I don't know what you mean by "normal database".  The test runner
essentially does a syncdb on the test database -- thus, it will create all
the tables for all the models for all the apps listed in INSTALLED_APPS.  If
you are seeing behavior different from this we'll need more specifics about
what exactly you are doing and what tables, specifically, are missing in
order to help figure out what is going on.

I don't have a very concrete example, but the high level thinking is
pretty easy to write out.  Typically, you would store your templates in
some kind of templates directory on the file system.  This doesn't work
well for your problem, as you want Admin type people to be able to edit
the templates, and you might even want some kind of revision control on
them.

Instead, you can make a table in your DB in which to stuff the
templates.  Maybe something like this:

class WebTemplate(models.Model):
template = models.TextField()
version = models.PositiveIntegerField(unique=True)
# Use this to store which page the template is for, like 'home'
page = models.CharField(max_length=)

When you create your template object, make it from the text in the
template field, and look for the entry with the highest version.  When
somebody edits the template, you just create a new instance and
increment the version number.  Make sense?  If you don't need revision
control, then you can simplify this, but I think it's pretty simple as is!

# Put strings here, like "/home/html/django_templates" or "C:/www/
django/templates".
# Always use forward slashes, even on Windows.
# Don't forget to use absolute paths, not relative paths.
)

but i get the error :

TemplateDoesNotExist at /richiedi/

richiedi.html

Request Method: GET
Request URL:http://mysite.net/richiedi/
Exception Type: TemplateDoesNotExist

and i see that he try to find the template here:


Template-loader postmortem

Django tried loading these templates, in this order:

* Using loader
django.template.loaders.filesystem.load_template_source:
* Using loader
django.template.loaders.app_directories.load_template_source:
  o /home/luca72/webapps/django/lib/python2.5/django/contrib/

But if in the setting i have write TEMPLATE_DIRS = ('/home/luca72/

Why he try to find it in /home/luca72/webapps/django/lib/python2.5/
django/contrib/admin/templates/richiedi.html

Re: Saving Oracle Connection across requests

[Jani Tiainen]

There exists Oracle connection pool daemon and django backend to utilize 
it. Check http://code.google.com/p/pyorapool/

Connecting to Oracle is rather slow operation and if possible you really 
like connection pooling.

Though even I'm using ajax based system to rather db intensive app that 
gets quite lot of request so far I've not seen necessity to use 
connection pooling. Normal roundtrip (django server is on different 
hardware than Oracle, connected using gigabit backplane) normal 
roundtrip is around 350ms. More speed could be obtained with Django 
caching mechanisms.

Re: how to return ajax info in one case, and redirect to a different url in another?

[Alex Robbins]

Making the browser switch pages isn't too bad. Just set
document.location to the new url using javascript. (The document
object should be provided by the browser.)
Maybe you should check the headers of the ajax response and if it is a
redirect make the redirect happen using javascript? Or simply make one
of the ajax responses be {"redirect_to": "http://www.example.com/"}
and parse it out on the client side.

Hope that helps,
Alex

dynamically add m2m field to model

[Aljosa Mohorovic]

i'm trying to dynamically add m2m field to model, any tips on how to
make it work?

# models.py
# after MyModel definition
if getattr(settings, 'MYMODEL_M2M', False):
app_label, model_name = settings.MYMODEL_M2M
model = models.get_model(app_label, model_name)
new_field = "%s_m2m" % model_name
setattr(MyModel, new_field, models.ManyToManyField(model))

opts = MyModel._meta
setattr(opts, new_field, new_field)

Putting the BOM in the template file worked for me, except that
Emacs's character code conversion (or something else below xml-mode)
ate it.  After asking for help at Stack Overflow [1], I ended up
redefining render_to_response:

def render_to_response(*args, **kwargs):
bom = kwargs.pop('bom', False)
httpresponse_kwargs = {'mimetype': kwargs.pop('mimetype', None)}
s = django.template.loader.render_to_string(*args, **kwargs)
if bom:
s = '\xef\xbb\xbf' + s.encode("utf-8")
return HttpResponse(s, **httpresponse_kwargs)

I can now do render_to_response("foo.xml", mimetype="text/xml",
bom=True) in order to prepend the BOM to a particular response.

Re: how to return ajax info in one case, and redirect to a different url in another?

Could you just do validation in the view, then when you get the
response, if there are no errors, submit the form with javascript
(form.submit()), handle it in the view and redirect?

Re: File Field max size and admin interface

It's pretty straightforward to subclass django.forms.fields.FileField to
apply a size limit in clean(), or perhaps just do the check in your
form's clean()  However, that way only checks when the upload itself has
already taken place to temporary storage. That still means you can
disallow uploaded files  above a certain size being saved to more
permanent storage though, which may well be adequate.

Something like:

from django.forms import fields

class SizedFileField(fields.FileField):
default_error_messages = {
'large_file': u"File exceeds size limit.",
}

def __init__(self, *args, **kwargs):
self.max_filesize = kwargs.pop('max_filesize', None)
super(SizedFileField, self).__init__(*args, **kwargs)

def clean(self, data, initial=None):
f = super(SizedFileField, self).clean(data, initial)
if f is None:
return None
elif not data and initial:
return initial

if self.max_filesize:
if data.size > self.max_filesize:
raise fields.ValidationError(
self.error_messages['large_file'])

return f

Hi,
   This might help:
http://www.djangobook.com/en/2.0/chapter07/
http://docs.djangoproject.com/en/dev/topics/forms/#topics-forms-index

  It will be good to read the djangobook (first link) once thoroughly
because all the basic scenarios are considered there. The
documentation in Django website is also very extensive. Do check it
out too.

Regards
K

Legacy db & 'serial' pk's

[Tim Bowden]

I'm new to Django, and trying to build a small app against a legacy
database.  A couple of the tables have primary keys of the form:
pk_field integer default nextval('pf_field_id_seq'::regclass)

I've used inspectdb to get a starting models.py, but how is this best
handled in django?

Thanks,
Tim Bowden

Re: Remote login via XML-RPC or SOAP?

[djfis...@gmail.com]

SOAP and XMLRPC have quite a few tradeoffs, but without knowing
exactly what your setup is (other than Python/Django) I'd advise you
to go with XMLRPC. However, I'll lay out why I think so and perhaps
SOAP does make more sense for you.

SOAP is the successor to XMLRPC and some people -- notably people from
the Java and .NET worlds -- think that SOAP is "better". In the Java
and .NET worlds, SOAP is pretty common but a lot of the scripting
language worlds are moving toward a third option REST which I won't
get into here since it doesn't seem to be an option for you. With
Python, XMLRPC is built into the standard library where you'll have to
go to Pypi for a SOAP library. Rolling your own SOAP library is
probably not a good idea since SOAP is complex and verbose. In
addition, there are occasionally incompatibilities with .NET SOAP
services or so I've been led to believe from others at work.

While SOAP is certainly more complex, in some cases it can make up for
it with type checking, code generation or object translation. SOAP
services usually make use of a web service description language
document (WSDL) that describes the service and can contain XML schemas
that describe in great detail the properties of the objects in the
service. Using this, a SOAP library may be able to automatically take
native objects and send them in web service calls or take web service
responses and translate them into objects. It is possible that with a
good library, you may need to write less code with SOAP. In general,
XMLRPC in Python will translate your objects into requests and
responses into objects, but XMLRPC only supports a few data types
(int, float, list, dict, datetime) compared with SOAP. Possibly
because of this lack of complexity, XMLRPC is pretty well standardized
between various clients and servers. If you just need to use a couple
services that your client is exposing and those services accept just a
couple primitive parameters, XMLRPC is your best bet.

Django generate unique sequence for each organisation in a SaaS app

[Sid]

I'm working on a django SaaS app, which hosts data for multiple
organisations. Each record in a table has a unique RecordNumber.

I could use autofield to give each record a unique incrementing Id
automatically, but that is globally unique. As in org1 might have say,
RecordNum=1 or 2 or 7 etc and org2 might have RecordNum=3,4,5,6

I want each organisation to have its own sequence, i.e. all
organisations might have RecordNum=1 or 2...etc. I can still use
autofield as primary key to identify the row. But i need the RecordNum
field as it will be visible to the end users as sequence numbers
within their org.

UUID, are too cumbersome to type in while searching for a record.

I found this - 
http://stackoverflow.com/questions/1104741/generating-sequential-numbers-in-multi-user-saas-application
But i before resorting to stored procedures, i want to make sure there
isn't any other way.

Ohh and btw i'm on MySQL.

Re: Can all of unicode be slugified?

[Continuation]

What's the best way to implement unicode slugification?

I have an application that expects Chinese characters (with some
English mixed in) in user inputs. What's the best way to turn that
Chinese-English mix into a slugified URL that's SEO-friendly as well
as meaningful to humans?

how to return ajax info in one case, and redirect to a different url in another?

[Margie Roginski]

I have a situation where the user fills in a form and hits submit to
post the form.  If my views.py code detects an error in the form, I
want to return some info to the client and put it into the dom via
jquery.  If there is no error, I want to redirect to another page.
Can anyone advise me on the best way to do this?  I've succesfully
used $.post() to grab the error info and put it in the dom.  However,
in the case where there is no error, I can't figure out how to do the
redirect.

I've tried having the views.py code pass back the url that I want to
redirect to, and then when my $.post() callback function is called, it
sets window.location to that url.   But this seems to have some issues
when the url contains an anchor (for some reason firefox seems to
cache anchored urls and not redirect to them in the normal way).

Is there any way to specify that even though $.post() started the
server request, that the server should just redirect to a url (ie,
using just the basic HttpResponseRedirect() or something like that)
and not return and call the $.post callback function?

Thanks for any pointers,

Margie
