Running doctests
Hello ! I have an app that has a "utils.py" module. I have written quite a few doctests inline. Now my problem is to actually run those tests. Reading the documentation, I get the feeling that I should be able to call them from the tests.py file, but I cant find an example. I have seen a few projects where there is doctests in tests.py that test other modules, but it seems to me that this defeats the purpose of having the tests inline, very close to the implementation. Did I miss something ? Thanks for your help !

Re: Working but ugly model code. Need advice.
If you just want to have a clean working solution, have a look at
django-photologue (http://code.google.com/p/django-photologue/). It is
amazing, and really easy to integrate well. Also have a look at
sorl-thumbnail (http://code.google.com/p/sorl-thumbnail/).
If you want to write your own code and make it a bit cleaner, I think
you should first try to break things a bit more
(http://en.wikipedia.org/wiki/Separation_of_concerns). For example,
having different picture sizes is a presentation problem, not a
persistence problem. So if you solve the that in a template tag, it
will probably be much cleaner.
Just my own 2 cents ... and yes, I know that I didnt really answer
your question ... sorry
Good luck !

"core" is not a field constructor argument anymore
Hello ! After updating to the latest trunk, I get a couple of errors when I have field that define "core=True". After digging into the code, I find changeset 8616 (http://code.djangoproject.com/changeset/8616) that documents that.

Again, without understanding how the users log into the server, we can
only guess ...
SAMACCOUNTNAME makes me think about Windows (SAM = Security Account
Manager), but that's just based on the name, and that name could well
mean something else in your context.
>From what I understand, the name is stored in an environment variable
(but I dont know how it gets there). Usually, the environment of a
process isnt changed from the outside after creation. And Django is a
long running process, so it should not pick up users logging in after
startup. But I can be completely wrong on that one ...
Assuming I am wrong above, you should be able to access the same
environment variable from python code with :
import os
loginbruger = os.environ['AUTHENTICATE_SAMACCOUNTNAME']
More infos on http://docs.python.org/lib/os-procinfo.html
The real problem I see there is that if there is multiple users
connected to the server, I dont see how the right user could be
associated with an HTTP session ...
Good luck, and please, try to get the info on how the login process works !

So what you seem to be looking for is a Single Sign On (SSO) solution. I dont know of any standard way to do that under Linux, but if you are using Windows, there is a standard mechanism for that. I think it is based on Kerberos and integrates with Active Directory. I'm far from a Windows expert, so dont ask me for the details, but I have been using this solution : * use IIS as a front proxy, IIS will do the authentication * IIS will forward the request to the backend server (in your case Django, running on Apache or even running on IIS) * the request is forwarded with additional HTTP headers describing the authentication (including the username) * you can then write a specialized authentication middleware that will use those headers to associate the session with the user > So after they are logged into the webserver it would be fair to assume > they are authorised users and if i could just locate their OS username > somehow then i could use this username to login the current user, in > the background with a standard password. > > I hope you get my meaning:) > > i have looked into the python standard library, and a module named > getpass() however i cant get i to work:-( > > i hope someone has a clever idea to solve this problem. > > Thanks! :) > > /Pete > > PS: and the webserver runs linux. :-) > > > -- Jabber : [EMAIL PROTECTED] Skype : Guillaume.Lederrey Projects : * http://rwanda.ledcom.ch/ * http://trock.ch/ Others : * http://kiva.org/ --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: time and attendance management system
Your question is very general, so it is difficult to give you a meaningful answer ... If you give us a much more precise description of your problem, or if you ask much more specific questions, you might get a useful answer. Here is a probably completely off-topic answer : You will make your employee database using Django model as described in the tutorial (http://www.djangoproject.com/documentation/tutorial01/#creating-models) or described in more details in the documentation (http://www.djangoproject.com/documentation/model-api/). You might also find appropriate examples in http://www.djangoproject.com/documentation/models/ Good luck !

Re: urls() and request.user

I finally choose to create a decorator to implement this

to do the same, the code is at
http://www.djangosnippets.org/snippets/753/
Of course, any suggestions of improvements are welcomed ...

I havent done any functional programming in a long time , but ... isnt
there a way to use an anonymous function (if that's what it is called)
and do the wrapper "inline" ? Something like :
urlpatterns = patterns('',
('^pattern/$', lambda(request)(
return update_object(request, ...)
),
)

urls() and request.user
Hello !
I am trying to use the update_object generic view in
http://www.djangosnippets.org/snippets/635/
I am using it directly in my urls.py like this :
url(r'^(?P\d+)/edit/$',
permission_required('change_news')(update_object),
{
'model' : News,
'model_form' : NewsForm,
'login_required' : True,
},
),
which works fine. Now, I am trying to add an extra field like this :
url(r'^(?P\d+)/edit/$',
permission_required('change_news')(update_object),
{
'model' : News,
'model_form' : NewsForm,
'login_required' : True,
'extra_field' : {
'author' : request.user,
}
},
),
This of course doesnt work because the request isnt in the scope. I
could redefine a view in my views.py and do the work on the request
manually, but i have a feeling there is a solution to do that directly
in my urls.py.
any idea ?
Thanks !
Guillaume

date_based.archive_index and "IS NULL" query
Hello !
I am getting a strange query from the archive_index generic view :
SELECT DISTINCT CAST(DATE_FORMAT(`news_news`.`publication_date`,
'%Y-01-01 00:00:00') AS DATETIME) FROM `news_news` WHERE
`news_news`.`publication_date` IS NULL ORDER BY 1 ASC
I dont understand where the "IS NULL" comes from. As all the news in
my database have a publication_date, this query returns nothing and no
news is displayed.
Any help appreciated !
Here is my ulrs.py :
urlpatterns = patterns('',
url(r'^$',
date_based.archive_index,
{
'queryset' : News.objects.all(),
'date_field' : 'publication_date',
'allow_future' : True,
},
),
)
and the model :
class News(models.Model):
""" News model """
title = models.CharField(max_length=100, unique=True)
slug = models.SlugField(prepopulate_from=("title",),
unique_for_date='publication_date')
author = models.ForeignKey(User)
creation_date = models.DateField(auto_now_add=True)
modification_date = models.DateField(auto_now=True)
publication_date = models.DateField(blank=True, null=True)

Re: Which kind of model inheritance is most suited?

Hello ! In my experience, inheritance is overkill in this case. Composition is very often a better alternative. In most cases, if you can express your model both with inheritance and with composition, you should use composition. Let's be a bit more clear : In your case, you can model with composition : a user has a function (seller or buyer). It gives you a bit more functionnality (a user can be both a seller and a buyer) and a bit more flexibility (a buyer can become a seller, or the opposite). Inheritance is a very strong relationship. It cant be changed dynamically. It should be used carefully ... Good luck !

That's the kind of solution I was thinking about. I actually would like all of my DateFields to have a calendar widget. Is it possible to register a custom Date widget as the default widget used by ModelForm ? Being able to create the Forms from the Models is a great simplification for all the simple UI. It gets a bit less simple if all those forms have to be customized to include a CSS class ... Thank you for your help !

DateField widget, ModelForm and javascript
Hello !
I have a model that I try to edit with a ModelForm. This model has a
DateField property. I render the form in my template with a simple :
{{ form.as_p }}
I expected the DateField to be displayed as in the admin interface,
with a javascript date picker. But I only get a text field. The value
format is validated as a date format, so I expect the field is treated
as a DateField.
Is there a way to automagically get the javascript date picker, or is
it something I have to add manually ?
Thanks for your help !
MrG

I am choosing framework for IMHO : scalability & sqlite are not words I would put together that easily. But I have to admit I havent dont any measurements. I have no idea how Django can help you to solve your problem (I am pretty new to Django) but I would suggest that you do some more research on the exact scalability requirements that you have ...

Having your production team agree to deploy python apps on the production server is probably the hardest part ! Jokes apart, here is a couple of things I would not know how to do in Python. Maybe they exist (I'm far from a Python / Django expert) : * distributed transaction (2-phase commit) * a good admin console so that a production team can : - tune database connection pools easily - deploy to a server farm easily (for availability) - other day to day admin tasks ... The admin console probably exists at some place like Google (or other big Python fans) but is not readily available commercially (read as : with commercial support). And that is a no-go for most of the enterprises I know ... -- Jabber : [EMAIL PROTECTED] Skype : Guillaume.Lederrey Projects : * http://rwanda.ledcom.ch/ --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.
