Re: Sick of defining urls

[Todd Blanchard]

I think you've kind of missed my point as there's not a view that can render 
any object - but rather the name of the view is in the url.

This is the url conf for a typical rails app.

  map.connect '', :controller => "public"
  # Install the default route as the lowest priority.
  map.connect ':controller/:action/:id.:format'
  map.connect ':controller/:action/:id'

That is the whole thing.  Controllers are analogous to applications in django, 
actions are like view functions, id is typically the primary key of the object 
being viewed.  format is new and could be .json, .xml, .html. I don't 
really use it just now.

I see no reason ever to specify a more elaborate url.  I want the equivalent 
setup in my urls.py and then I never want to open that file again - relying 
entirely on naming convention rather than configuration.

You've kind of pointed me in the right direction though.  After a day of 
hacking about I ended up with:

urlpatterns += patterns('',

(r'^(?P[^/]+)/(?P[^/]+)/(?P[^/]+)\.(?P[^/]+)',dispatch_request),
(r'^(?P[^/]+)/(?P[^/]+)/(?P[^/]+)',dispatch_request),
(r'^(?P[^/]+)/(?P[^/]+)\.(?P[^/]+)',dispatch_request),
(r'^(?P[^/]+)/(?P[^/]+)',dispatch_request),
(r'^(?P[^/]+)\.(?P[^/]+)',dispatch_request),
(r'^(?P[^/]+)',dispatch_request),
)

def dispatch_request(request, app, view='index', id=None, format='html'):
"""
Implements Ruby on Rails 'Convention over Configuration' Policy

Along with rules in urls.py, implements urls of type
/application/view/id.format
which is analogous to Rails's
/controller/action/id.format
"""

view_module = None
view_function = None

# if debug, let the exceptions fly - otherwise make them 404's
# try to import the application module, then lookup the view function in it
if settings.DEBUG:
view_module = __import__(app+'.views', globals(), locals(), [ view ], 
-1)
view_function = (view_module.__getattribute__(view))
else:
try:
view_module = __import__(app+'.views', globals(), locals(), [ view 
], -1)
view_function = (view_module.__getattribute__(view))
except ImportError:
raise Http404

# make the GET mutable and stick format and id on it if non-nil
if request.GET:
request.GET = request.GET.copy()
else:
request.GET = QueryDict('').copy()

request.GET.__setitem__('format',format)

if id:
request.GET.__setitem__('id',id)

# call the view function
result = view_function(request)

# if the view didn't render anything, lookup the template by convention and 
render it
if result == None:
result = render_to_response(app+'/'+view+'.'+format,{'app': app, 
'view': view , 'id': id, 'format': 
format},context_instance=RequestContext(request))

return result

and this gives me most of the convention of rails.  No more fiddling urls.py.

The only improvement would be to make the functions in views.py methods on an 
object (the "controller") and bind its ivars into the request when rendering 
the template.

Re: django error page: traceback too shallow?

[notcourage]

def home (request):

if (request.user.is_authenticated()):
artifacts = Artifact.objects.filter
(member__exact=request.user.profile.id)
...
else:
...

In this case, the user is authenticated but the predicate is failing
as expected because user.profile is NULL. The traceback is just odd.

I was thinking that perhaps if you'd like to learn more about approaches to
what you're doing, you could look up things that have been written about
storing directed acyclical graphs in relational databases.  That's
essentially what you're doing.  You may even conclude that a relational
database isn't the right data store... but that's what Django was built for,
of course.

If you want to scale, really scale, you'll want to use a graph library.
There are several for Python, including NetworkX, which I've used, and
Boost, which I haven't.

Probably more info than you wanted, but there it is.

Custom User Model, Django Admin, and the password field

[Justin Steward]

Hi,

I've created a custom user model in my application by subclassing
django.contrib.auth.models.User. This user model is working, but there
are a couple of problems I have with it.

1) The change password link in the admin site doesn't work?

2) The default password box on the add/edit page for a user is a
little unfriendly. Ideally, what I'd like is the two password fields
from the change password form on the add/edit user form in the admin,
which will automatically turn convert the entered password into a
valid encrypted password in Django.

This would make the admin system MUCH friendlier and much more suited
to my needs, as a fair number of user accounts will be created and
maintained manually in this app, and the person responsible for doing
so will likely be scared off at the sight of that admin field, or just
type a clear text password and wonder why it doesn't work.

Is this possible / How do I do this?

Why does create_user work without importing User from django.contrib.auth.models

[chefsmart]

I have been using django.contrib.auth for some time now. I have been
creating users and assigning them to groups successfully.

I do something like this: -

user = User.objects.create_user
(username=form.cleaned_data['username'],
 
password=form.cleaned_data['password'],
email=form.cleaned_data
['email'])
user.is_staff=True
user.first_name=form.cleaned_data['first_name']
user.last_name=form.cleaned_data['last_name']
group = Group.objects.get(name='B')
user.groups.add(group)
user.save()

However, I just realized that I have never done

from django.contrib.auth.models import User, Group

I don't understand why my code works without the proper import
statements!?

Exactly. So people need to be aware of the varchar limits of django_

It isn't clear to me that you want to avoid the effort of putting a user 
in or whether you really want to avoid having them in the Django database.

If you just want to avoid the effort and don't mind them being in there 
I can recommend Peter Herndon's django_ldap_groups ...

http://code.google.com/p/django-ldap-groups/

... which I have recently installed and it works very well.

This kit automatically inserts the user from the AD or eDirectory into 
the Django database complete with whatever info you want to extract and 
also putting them into Django groups you have related to AD or eD groups.

This lets users login with ldap auth and if the ldap server is down they 
can log into the Django app using Django auth.

Mike

Hi guys, thanks for responding. I didn't want to have to create 2

Importing users - salted sha1

[Dave]

I have a website with about 90 users that I'm trying to import into
Django. Right now, the users have a password with a salt and a hash,
so I tried (with a sample user) to format the password how Django
likes them. I did sha1$salt$hash and I wasn't able to log into admin
with that user (I made that user a superuser, staff, and active). I'm
using Django's auth authentication system. Has anyone run into this
before? Do I have to do something else to get this to work?

Thanks in advance!

But when I use that code, it is still saving the User model instance.
I know, because the next time I log in I get a "Duplicate entry". I

Re: Initial values for formwizard form

[geraldcor]

Ok, so I'm a little embarrassed as usual. basically I was checking for
a step without defining it. I assumed I could just use the step that
is passed but that didn't seem to work for the if statement. So I just
eliminated the if statement and all is well. Not perfect, but I can at
least move on.

You haven't done anything to express the reverse relationship, if I
understand all this correctly, so of course it doesn't show up.  A
straightforward way to solve that would be to simply add the reverse entry
at the same time you add the initial entry, since you are assuming the
friendship is bidirectional.  In other words, at some point when you save a
form, you're creating a row like this:

rel = Friendship.objects.create(to_friend=user1, from_friend=user2)
rel.save()

But are you doing the reverse?

rel = Friendship.objects.create(to_friend=user2, from_friend=user1)
rel.save()

There are other ways to accomplish it, but I think this is the simplest.

Re: Initial values for formwizard form

[geraldcor]

So I successfully used this method to add initial values using
parse_params as I was dealing with step 0. However, now the client
wants the form order changed so that what was step 0 is now step 2. I
tried using process_step in the exact same way as parse_params, but
the values are not filled in. I can't figure out how to use
process_step like I was able to use parse_params.

this is what I tried

def process_step(self, request, form, step):
profile={}
profile=request.user.get_profile()
if step == 2:
init={
'company': profile.defaultcompany,
'contact': profile.defaultcontact,
'address1': profile.defaultaddress1,
'address2': profile.defaultaddress2,
'address3': profile.defaultaddress3,
'city': profile.defaultcity,
'state': profile.defaultstate,
'zip': profile.defaultzip,
'country': profile.defaultcountry,
'faxareacode': profile.defaultfaxareacode,
'fax': profile.defaultfax,

Re: A Friendship relationship question.

[aa56280]

Couple things:

1) Your query is not working because if user1 added user2, then you
should be looking at from_friend not to_friend.

2) You haven't posted the code where you're creating friendships but
I'm assuming you are not creating symmetrical friendships there. That
is, if user1 adds user2, you create a record in the table and you move
on, but you need to create another record to symbolize the friendship
the other way around. Have a look at symmetrical ManyToMany
relationships and see if it's possible to go that route - it actually
uses a friends example :-)
http://docs.djangoproject.com/en/dev/ref/models/fields/#django.db.models.ManyToManyField.symmetrical

Hope that helps.

File in admin with TabularInline don't get uploaded

[Marcos Marín]

Hi,

I have a site where you can create news items that can have attached files.
I'm using TabularInline so the the admin interface shows attached files in
the same view where you create the news items.

When I create a new news item and attach files it gives no errors, but the
file isn't actually uploaded to the server.

I have checked:

   - The generated html form in the admin view has enctype="
   multipart/form-data"
   - The folder to where it should be uploaded has the necessary permissions
   (I'm sure because I have uploaded files for other models to the same folder
   and they work).
   - The database tuple is created corectly for both the news item and the
   attached files

Everything seems to go fine except the folder where the file should be
uploaded does not have the file.

I'm running out of ideas of what the problem could be, anyone have any?

A Friendship relationship question.

[Jeffrey Taggarty]

Hi,
I am having difficulties with listing this type of data. Scenario is
as follows:

1) user1 add's a friend called user2
2) user2 confirms that user1 is his friend

what should happen is user2 and user1 see's each others name in their
friends list. What's happening now is I am able to add user2 to user1
friends list but user1 cannot see user2 in his/her list. My question
is how do I get user1 to show up in user2's list and user2 to show up
in user1's friend list if a user has confirmed friendship? I was
thinking of utilizing the confirmation status in the model and because
that user1 and user2's id is both in the confirmed relationship I
don't see any integrity issues here. Any tips?

Friendship model:

class Friendship(models.Model):
NOT_CONFIRMED = 1
PENDING= 2
CONFIRMED = 3

STATUS_CHOICES = (
(NOT_CONFIRMED, 'Not Confirmed'),
(PENDING, 'Pending'),
(CONFIRMED, 'Confirmed'),
)
from_friend = models.ForeignKey(User, related_name='friend_set')
to_friend = models.ForeignKey(User, related_name='to_friend_set')
confirmed = models.IntegerField(choices=STATUS_CHOICES,
default=NOT_CONFIRMED)

class Meta:
unique_together = (('to_friend', 'from_friend'),)

def __unicode__(self):
return '%s, %s' % (self.from_friend.username,
self.to_friend.username)

Views to render the friendships (as you can see, I have been playing
with the filtering):
@login_required
def friends_list(request, username):
user = get_object_or_404(User, username=username)
#friends = [friendship for friendship in user.friend_set.filter(Q
(confirmed=2) | Q(confirmed=3))]
friends = Friendship.objects.filter(
Q(to_friend=user) | Q(confirmed=3)
)

# get friends latest 10 shows
friend_shows = Show.objects.filter(user__in=friends).order_by('-id')
return render_to_response('habit/friends_list.html', {
'user': request.user,
'friends': friends,
'shows': friend_shows[:10],
'username': username,
})

You'll have to "activate" the model like any other in order for it to
show up on the Admin site.

The form you are getting sounds like the right one.

You'll get a username field and a password field, but you'll have to
provide your own  tag and submit button.

Have a look at the sample login template:

Capturing common data from all URLs

[Dave Dash]

Hi,

I'm working on porting a legacy site (addons.mozilla.org) where all
urls begin with /locale/app/:

e.g.

https://addons.mozilla.org/en-US/firefox/
https://addons.mozilla.org/ja/firefox/addon/5890
https://addons.mozilla.org/en-US/thunderbird

and in some cases, the application is not needed:

http://www.mozilla.com/en-US/about/legal.html

I know I can use django-localeurl to capture the locale, but I'm
wondering if there's a more generic middleware that can capture
anything (and store it in the request object) based on configuration?

Cheers,

-d

Re: Returning Django objects from Ajax request

I'm using jQuery post:

 $.post("/getRestaurant/", location,
function(data) {
/* stuff */
});

In my view, how do I convert my Restaurant array to json?

Thanks for your reply!

if you're using jQuery's elm.load(url) function, you have to return an
HTML fragment to replace the one already in the browser; so use a
template that renders just this fragment.

if you use a JavaScript template (there are several jQuery plugins),
just return the data in JSON.

Returning Django objects from Ajax request

[jul]

hi,

I'm using jQuery to send data to a view with is supposed to return
some Django objects (instances of a Restaurant model). Here's what I
do
1- some javascript detect the user's location in the client side
2- the location is sent to a view which select some instances of my
Restaurant model
3- these instances must be returned to the template.

How can I return these objects to the javascript in my template?
I'm not using render_to_response with my objects in the context since
I think it reloads the whole template? Is that right?

thanks
jul

Hello Bill,

I haven't seen your reply at first... Slow receiving from mail-client.

I've done as you said, and yes, I successfully browse all modules when
running `manage.py shell`, but because I was using directly using
Python, I received just the limited output.

Thanks for the explanation.

Kenny

Hi Frank,

Well that's strange... I don't get similar output, but see it yourself:

>>> import django
>>> dir(django)

Re: Browsing Django modules from interactive python shell

[Bill Freeman]

import a

does not automatically import modules and sub packages of package a.  It takes
special action in a's __init__.py to make this happen as it does for
os.path when
you import os.

I assume that you're doing this directly in python, since in the manage.py shell
other stuff has already caused django.core to be imported, so it's available.
(And Frank was probably using the manage.py shell, thus finding that he
didn't have to separately import django.core .)

Browsing Django modules from interactive python shell

[Kenny Meyer]

Hi guys,

I have some strange behaviour in my interactive python shell, when
trying to browse Django modules...

Example:

>>> import django
>>> dir(django.core)
AttributeError: 'module' object has no attribute 'core'

>>> import django.core
>>> dir(django.core)
['__builtins__', '__doc__', '__file__', '__name__', '__package__',
'__path__']

Can anyone, please, explain me this strange (to me) behaviour?

Kenny

inlineformset and related instance creation at once

[andreas schmid]

hi,

im trying to create a form based on 2 models where model B will be a
inlineformset related to model A.
how can i tell the formset forms (model B) that the related instance is
the just created instance based on model A?

lets say i want to create the author and assign him many books in one shot.
i get the form displayed but after the submit i get a:

Cannot assign "": "Book.author" must be a "Author" instance.

  

http://docs.djangoproject.com/en/dev/topics/forms/modelforms/#using-an-inline-formset-in-a-view

only tells how to create Book instances related to an existing author.
(i admit i didnt try to hard today)

another question i have is: do i have to define the amount of books in
advance with extra= or is there a way to get a plus icon where i can
click on and get a formset.form more displayed?
http://docs.djangoproject.com/en/dev/topics/forms/formsets/#s-adding-additional-fields-to-a-formset
here i can see an explaination about how to add fields... i would need
something like can_delete or can_order but for adding new forms to the
formset.

thank you

Re: Django and Authorize.net

[Chris Moffitt]

Bruce has been working to split out the payments from Satchmo into a
standalone app called django-bursar -
http://bitbucket.org/bkroeze/django-bursar/overview/

Check that out and see if it meets your needs.

I've also heard about this library but have not used it -

Re: missing template for login page

I'm very interested in this as well. I wrote almost all the forms and  
logic to do what this module already does :/

I should lrn2RTFM! but that's been an uphill battle for many ppl ;)

missing template for login page

[Andreas Kuntzagk]

Hi,

I try to get user authentication working. I followed the advice on 
http://docs.djangoproject.com/en/dev//topics/auth/#django.contrib.auth.decorators.login_required
 
to use the login_required decorator. I also get forwarded to 
http://bbc:8000/accounts/login/?next=/blabla
url.py for this reads:
(r'^accounts/login/$', 'django.contrib.auth.views.login'),

but then it complains about a missing template registration/login.html

I tried copying /django/contrib/auth/tests/templates/ to 
/django/contrib/auth/ but this gives me a form with only two fields and 
  no submit button so it's probably the wrong template. Where do I find 
the right one or do I have to write it on my own.

regards, Andreas

Re: loaddata encoding problem

[Johan]

Hi Ian,

I do have NVARCHAR2 columns and the NLS_NCHAR_CHARACTERSET is
AL16UTF16 in both schemas.

When trying to decode and encode according to your instruction I get:

UnicodeEncodeError: 'latin-1' codec can't encode characters in
position 4171134-4176189: ordinal not in range(256)

When looking at that position in the file I discovered that we had
some "chinese" chars there. And they shouldn't be there (-there seems
to be a problem when the size of a oracle CLOB field is exceeded).

So now I fount out what the problem is and I thank you for your
help..

Regards,
Johan

Re: Inlineformset_factory and User model

[Frank DiRocco]

request.user will give you the User object from the  
django.contrib.auth.models, but Authors has no relation.

If you slightly modify your Book model to make authors relate to the  
above module, you can eliminate the Authors Model and the "user" of  
you Book model.

class Book(models.Model):
...
authors = models.ManyToManyField(User, related_name='Entries')
...

Now in you view, all you have to do is:
def add_books(request):
if not request.user.is_authenticated():
return HttpResponseRedirect("accounts/login")
if request.method == "POST":
formset = BookFormSet(request.POST)
if formset.is_valid():
formset.save()
return HttpResponseRedirect('books/latest.html')

I'm a n3wb so, I'm fishing to see if I'm understanding the same :]

Re: Help with installing MySQLdb package for Django on OS X Snow Leopard

[Andy Dustman]

To sum up (because I've been helping him off list too): It looks like
he had old versions of setuptools and XCode (from OS X 10.4, running
10.6). I think once XCode gets upgraded, he should be OK... assuming
MySQL is actually installed...

As for ZMySQLDA: SourceForge features the most release of any project
files, and that happens to be the latest one. I'm planning to spin off
ZMySQLDA into a separate project, because I don't work on it any more;
John EIkenberry is developing it now.

Django and Authorize.net

[Chris McComas]

Greetings,

We have an application for our school online, just recently the
university controller and business office finally gave us clearance to
accept our application fee online, and they setup an account with
authorize.net.

I'm trying to integrate the payment within our Application app, I was
curious if anyone had done any one-off payments with Django/
authorize.net, or if there were and pluggable apps out there (I know
Satchmo, that's my backup plan).

Thanks,

Chris

No, they're not 'for' anything. They're source code, which you compile

Hello everyone,

A small announcement about mod_auth_django. A small Apache module which let you 
authenticate Apache on the Django database.

This module is intended for Apache instances not running on the Django server, 
but with access to the Django database. It is a small modification over 
mod_authn_dbd to use Django password format.

Module page: http://bitbucket.org/kuon/mod_auth_django

Here's the culprit:

File "D:\Python25\lib\site-packages\django\contrib\auth\management 
\__init__.py", line 28, in create_permissions defaults={'name': name,  
'content_type': ctype})

Do you have any custom-defined permissions for your models?

MySQL error 1406 while running syncdb

[chefsmart]

Hi, I'm am getting MySQL error 1406 while running syncdb. (See link
http://pastebin.org/59605)

This happens after I create the superuser.

The error says _mysql_exceptions.DataError: (1406, "Data too long for
column 'name' at row 1")

I am not doing any pre-population of data. So I checked the tables
whose names start with "django_" and columns called "name" appear for
the django_content_type table and the django_site tables. The former
is varchar(100) and the latter is varchar(50).

I am definitely safe as far as the django_site table is concerned. And
I am also safe with the django_content_type table so I'm not sure why
this is happening.

Where does Django populate the django_content_type.name column from? I
am guessing it would take the model name or the verbose_name if
supplied.

All my models are named well within the varchar(100) limit.

Any idea what is going on? By the way, I'm also using contrib.auth.

Regards.

Uninstall what? Apache or mod_wsgi?

Also, what you need to do really depends on how you installed both,
whether from source code yourself or from binary packages. Too hard to
say as have no idea. If binary packages, follow your Linux
distributions documentation or use their tools appropriately.

Don't use 'processes=1' as it defaults to one process if that option
isn't set and setting has certain implications. That is explained in
description of that option in documentation I directed you to last
time.

Read that documentation again as well as:

  http://code.google.com/p/modwsgi/wiki/QuickConfigurationGuide

The documentation I referred you to last time describes what it should
be in the section related to that option. Specifically, colon
separated list of directories, exactly like PYTHONPATH user
environment variable. I even said to use exact same value as used for
PYTHONPATH in past post.

How is this question different to (3).

Also perhaps read:

  http://code.google.com/p/modwsgi/wiki/VirtualEnvironments

if you want to know more about setting Python module search path.

If you are a novice as you say, then try and endeavour to read
documentation you are referred to and also look at what other
documentation exists on that site, starting at:

  http://code.google.com/p/modwsgi/wiki/InstallationInstructions

Maybe using default as argument to your field?

The main 'Download Now' link from this page for some reason links to
the Zope adaptor. However you can click on 'View all files' to see the
actual packages for MySQLdb.

Of course if you're still having problems there's no requirement to
use MySQL in Django, you can just use sqlite3 which should work
without any additional requirements.

My first guess would be that destination file exists and `ln` doesn't
want to overwrite the file
First try moving file or directory named "django" from site-packages
somewhere else and then try to link again.

$ mv 
/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/django
/tmp/DJANGO_TMP
$ ln -s `pwd`/django-trunk/django /Library/Frameworks/Python.framework/
