Re: Django Login/Session Not Sticking

2014-06-05 Thread Juergen Schackmann 
*PLEASE HELP: I am not sure if this is a bug or caused by my code. But this 
is a serious issue for my production site.*


To get some more debug information, I have created this Middleware:


from django.conf import settings

class SessionDebugMiddleware(object):
def process_response(self, request, response):
session = request.session
user = request.user
session_key = request.COOKIES.get(settings.SESSION_COOKIE_NAME, 
None)
x_meta_requ = '{0},{1},{2},{3}'.format(session_key, 
session.get('_auth_user_id'), session.get('_auth_user_backend','---'), 
user.id)
response['X-Meta-Requ'] = '{0},{1},{2},{3}'.format(session_key, 
session.get('_auth_user_id'), session.get('_auth_user_backend','---'), 
user.id)
return response

If I hit the refresh button 10 times, 
8 times I will get this 
header: igv0xshezhdxh50kks9x00r0l67mx0sk,None,---,None
2 times I will get this header: 
X-Meta-Requ:igv0xshezhdxh50kks9x00r0l67mx0sk,330619,django.contrib.auth.backends.ModelBackend,330619

It seems be be random and does not follow any logic.

Are you sure all app servers are running the same code? Same settings.py? DNS 
load balancing you forgot about? Maybe you have some lingering app server 
processes that were never shut down? Check the start date of all WSGI processes 
to be sure.

Re: URLs: mymodel_id vs object_id vs pk ....

2014-06-05 Thread Thomas Güttler 

Thank you for answering my question.

Unfortunately "slug" does not work in my context.

My model does not have a "slug". It is like a ticket/issue system. There
are several hundred of tickets each day.

Am 04.06.2014 15:07, schrieb Thomas Güttler:

What is the best practice for named URL parameter which refer to a primary key 
of a model?

I have seen many ways:

  - object_id
  - mymodel_id
  - pk
  - id
  - .

example:

urlpatterns = [
 url(r'^article/(?P\d+)/$', 'article.view'),
 ...
 ]

Up to now we used "mymodel_id" but it gets boring to type in "mymodel".

This is a question about best practice:

Which do you use (and why)?

The simplest solution is to simply rename either app or component that

RE: safari ios 7 and django app - function not being called to serve video

2014-06-05 Thread Ilya Kazakevich 
Hello,

1) Use FireBug (http://www.hongkiat.com/blog/installing-firebug-browsers-ios/) 
to check generated HTML for correct link and HTTP request your browser 
sends/receives
2) Check your web server logs to ensure Safari tries to load video (you need 
access log and error log I believe: http://httpd.apache.org/docs/2.2/logs.html )
3) NEVER hardcode urls! Use URL tag 
(https://docs.djangoproject.com/en/dev/ref/templates/builtins/#url)

Thanks for your suggestions Ilya.

>From the apache side of things my serveAsset function is not called when
the page is viewed from an iPhone/iPad. But it works fine from a browser on

I changed to using the URL tag.

I really can't work it out at the moment.
I wonder if it is some configuration on the mac os x server that is running
the django app related to mobile devices?

Re: safari ios 7 and django app - function not being called to serve video

2014-06-05 Thread Adam Teale 
Ahh i just worked out the issue.

The server is using SSL certification (https?) and for some reason on the
iphone/ipad the serveAsset was not being called.

So now to work out how to call the URL tag with SSL.

Cheers!

RE: safari ios 7 and django app - function not being called to serve video

What algorithm is used for keys in HTTPS on your installation?
AFAIK, Safari@iOS does NOT support DSA keys (only RSA keys are supported).

Using custom user (AbstractUser) and django-registration

2014-06-05 Thread Arnaud Vandecasteele 
Hi guys,

I've been trying the whole day to use django-registration with a custom
user model.
Basically this is what I did :

*1/ Create a custom user model (models.py)*

class customUser(AbstractUser):
company_name = models.CharField(max_length=255)

--> My first question is do I need to add "objects = UserManager()" to my
model ?

*2/ Register my new user in the admin interface*

from django.contrib import admin
from django.contrib.auth.models import Group

from .models import customUser
admin.site.register(customUser)


*3/ Add my customUser to my settings.py*AUTH_USER_MODEL = 'myApp.customUser'

*Ok from this point everything works fine ! *

But my next step was to use django-registration [1] to have a full user
creation workflow.
After the installation, when I've tried to register a new user using the
registration forms, Django raised this error:
*django Manager isn't available; User has been swapped *

I've tried different things but none of them have worked.
The only solution I found [2] is by modifying directly django-registration:

Edit registration/forms.py, in the top change
from django.contrib.auth.models import User

to

from django.contrib.auth import get_user_model
User = get_user_model()

While I really don't like to change an existing application, after this
change I was able to use both django-registration and my custom user.

So I'm sure you can guess my question, is there no other way to do this ? I
really would like to keep my code clean without this kind of dirty hack.

Thanks

Arnaud

base.html template conflict

2014-06-05 Thread sergeig . public 
I have installed both oscar and mezzanine apps into the same project. I was 
able to see both working when isolated from the other.

oscar requires TEMPLATE_DIRS to have a custom location:

import oscar
TEMPLATE_DIRS = (
oscar.OSCAR_MAIN_TEMPLATE_DIR,
os.path.join(PROJECT_ROOT, "templates"),
)

When oscar.OSCAR_MAIN_TEMPLATE_DIR is defined, it stops mezzanine from 
working, because oscar's base template is used for everything. Commenting 
out oscar line, enables mezzanine to work.

I checked and default loader order is:
TEMPLATE_LOADERS = (
u'django.template.loaders.filesystem.Loader',
)   u'django.template.loaders.app_directories.Loader',
which explains this behavior.

I changed the loader order to:
TEMPLATE_LOADERS = (
u'django.template.loaders.app_directories.Loader',
u'django.template.loaders.filesystem.Loader',
)
and that stopped oscar from working, when TEMPLATE_DIRS is defined with 
both lines.

So, I am kind of confused how to address the issue. I know that in the long 
run I 'd like to use only one base.html for the entire site, but in the 
short run I'd like to see both working using their own default templates.


Thanks

Displaying an uploaded file in a form

2014-06-05 Thread Shawn H 
I've been trying to understand how to handle file uploads, and I've got the 
upload portion down.  I have a FileField in my form, process it in my view, 
and it's saved in the correct location as specified in MEDIA_ROOT and the 
upload_to attribute of the Model.  My problem is, when I try to bind the 
uploaded document in a GET request, nothing is working.  I tried following 
the documentation in the docs 
, 
but when I do that I get a 'FieldFile' does not have the buffer interface 
error.  How do I bind the file to the form so it's available to the user to 
download or open, while preserving the ability for the user to replace the 
uploaded file?  Do I have to extract the file from the model field before 
binding it to the form?  Code below.  Thanks in advance

form_data = {
'sub_id':s.id,
...
'sub_verified_by':s.verified_by
}
form_file = {'sub_pdr': SimpleUploadedFile('SubmissionPDR.docx', 
s.pdr_file)}
form = SubmissionEditForm(form_data, form_file)

I think you are trying to redisplay a form that has already been
submitted, with the file there? This is not going to work, mainly
because a file field in a form never has an initial value, but also
because it is the wrong approach.

To display all the fields apart from the file field, you should be
passing the form data to the form as initial, not as data - eg
SubmissionEditForm(initial=form_data) - so that you do not create a
bound form - a form that has been submitted already.

To make the file available to download, you simply add the url to the
file to your template context - s.pdr_file.url - and make a link to it
- no forms involved. Or just add 's', and access it in the template:

{% if s.pdr_file %}
Download file
{% endif %}

Cheers

Tom

2014-06-05 Thread JJ Zolper 

Hey everybody,

I really feel I could learn a lot from the experiences of developers working on 
high profile Django sites as I am working hard to begin that journey as well. 
And that is why I would love to have this project funded to 15k:

https://www.kickstarter.com/projects/1704706557/high-performance-django

"The next goal is at $15k and will help us include exclusive interviews with 
developers of high-profile Django sites as part of the package. We've already 
lined one up with an early Pinterest engineer and have calls out to a few 
others."

I've commited funds to every single Django project I have come across and I 
think we can do this!

Take it easy everyone,

JJ
