[James Bennett]

Yup, we're on the way to 1.7!

Check out the blog post (which mentions a couple of important issues to be
aware of *before* trying out the alpha):

https://www.djangoproject.com/weblog/2014/jan/22/django-17-alpha-1-released/

And the in-progress 1.7 release notes for a full rundown of what's going to

Re: ec2 using bitnami djangostack: application never loads; browser just hangs

[Dylan Bumford]

Thanks. I've checked apache's error_log, and it doesn't report anything 
unusual. The access_log reports about four hundred GET requests that look 
sort of like this:

10.73.205.233 - - [22/Jan/2014:18:07:34 -0500] "GET 
/img/ami-lower-container.png HTTP/1.1" 304 -
10.73.205.233 - - [22/Jan/2014:18:07:34 -0500] "GET /img/ami-list-item.png 
HTTP/1.1" 304 -


The last two lines are:

201.249.174.162 - - [22/Jan/2014:18:09:19 -0500] "HEAD / HTTP/1.0" 200 -
120.192.101.153 - - [22/Jan/2014:19:21:28 -0500] "GET /manager/html 
HTTP/1.1" 404 210


I don't know what other logs to check. When I run the app in DEBUG=True, I 
don't see any difference. If I introduce an artificial bug in 
*/mysite/mysite/urls.py*, it reports the bug through the Django debugging 
page (and also in error_log). But when I remove the bug, it's back to 
endless waiting. How can I tell if the request is making it to modwsgi or 
it's stuck in apache?

Django Model Primary Key help please...

[Amit Masaun]

Hi,

I am trying to port over something to Django/Postgresql that I built on 
Asp.Net/MSSQL and I was hoping someone could give me some direction on 
manual creation of Primary Key key columns in Django models.  What I would 
like is to have a BIGINT Primary Key value that is unique across all my 
models (which is what I am currently doing in Microsoft stack).  I have 
been researching for the last day and I dont see obvious pattern anywhere. 
 The closest thing I have found to what I need is django-ticketing:

https://github.com/streeter/django-ticketing

Unfortuantely it is very MySql-centric.

Are there any "best practices" for generating bigint primary keys which are 
unique accross multiple models? 

Thank you very much in advance.

--Amit

The link opens the release note for 1.4 which itself explains what to do.

Usually when Django deprecates a method, the replacement is 
simultaneously implemented so developers can adjust their code 
immediately without waiting for it to disappear and cause an error two 
versions later.

You are probably running Django 1.6.x which doesn't have
execute_manager.Here is the


er ... link


which explains that it is a deprecated method ...


https://docs.djangoproject.__com/en/dev/releases/1.4/#__django-core-management-__execute-manager




Little bit of work to do.

Re: Save to User table first_name and last_name from a page with a different form

[Brad Rice]

I think I figured it out. The user is on the reuqest so it was pretty easy.

def form_valid(self, form):
obj = form.save(commit=False)
obj.created_by = self.request.user
obj.application_id = self.kwargs['app_id']
u = self.request.user
u.last_name = obj.last_name;
u.first_name = obj.first_name;
obj.save()
u.save()
#reverse_lazy = lambda name=answers, *args : lazy(reverse, 
str)(name, args=args)
return HttpResponseRedirect(reverse('requestform:answers', 
kwargs={'app_id': obj.application_id}))

Re: ec2 using bitnami djangostack: application never loads; browser just hangs

[Andreas Kuhne]

1. Have you checked all of the access logs and error logs when the app is
started? Is your request getting served by modwsgi, or is it stuck in
apache?
2. Start the application with DEBUG=True in settings, to see if you get any
information from the app.

Thats where I'd start.

ec2 using bitnami djangostack: application never loads; browser just hangs

[Dylan Bumford]

I used the Bitnami Djangostack AMI to set up a Django environment with 
apache2 and mod_wsgi on a free instance provided by Amazon's EC2. The 
django app is installed at /opt/bitnami/apps/django/django_projects/mysite, 
alongside the default Project application that comes with the stack. The 
app runs on my local computer on the development server without issue. When 
I transferred the app to the server, I ran the collectstatic script to copy 
all of the static files to mysite/static, and configured the server to 
serve STATIC_ROOT at STATIC_URL (settings and configuration details are 
reported below). As best I can make out, I've configured everything in 
accordance with the Django 
documentationand
 
modwsgi 
documentation.

When I point my browser to the server's public address, I see the bitnami 
startup page, but when I point to the subdirectory mapped to the 
application, the browser just hangs. It acts as if it's loading a website, 
spins the little wheel to tell you it's loading a website, and says 
'Waiting for xx.xxx.xxx.xxx..." But nothing ever happens. There are no 
errors reported in */opt/bitnami/apache2/logs/error_log*. But If I point 
instead to a random subdirectory that doesn't exist, I get a 404 page. If I 
point to the static subdirectory, I get a 403 Forbidden page. If I 
purposefully add a bug to any of the python code (in e.g. 
*mysite/mysite/urls.py* or *mysite/myapp/views.py*), I get a 500 Internal 
Server Error and a message in the error_log with the expected python stack 
trace.

If anyone has any suggestions, I would obviously be very grateful. I'm 
pretty new to this.

Here are the relevant parts of my configuration files.

Save to User table first_name and last_name from a page with a different form

[Brad Rice]

I have a registration and login page that only takes username and password. 
After they register or login, they are taken to a profile form where they 
can provide additional information such as address and phone numbers. I'm 
using a Model Form CreateView there. On that page I want the First Name and 
Last Name fields to  save to the auth_user table rather than that Profile 
Form model. How do I have two fields submit data to the auth_user table and 
the other fields submit to the Profile table?

Read geometry column in geography field

[jorgearevalo]

Hello,

I want to read a PostGIS geometry column using a model that contains a
geography field. Is it possible?

The reason why I need to do it that way is because I just have read
access to that table, and I need to run distance queries using it. I'd
prefer to avoid writing raw queries, and use GeoDjango (more info at
http://gis.stackexchange.com/questions/83783/geodjango-read-geometry-column-in-geography-field
)

Anyway, many thanks in advance

While I will say that I love a lot of things about Nikola, it doesn't
meet the OP's requirement for authenticated users and sessions.

However, if the OP only needs those for commenting purposes, Nikola
does allow you to outsource those to an external service like Disqus
(several are supported).  But if the auth/sessions run more deeply in
the requirements, Nikola won't likely do.

Re: django with no relational db?

[graeme]

You do lose a lot without a relational DB: model forms, auth, admin. I 
think sessions should work as long as you do not use the DB backend.

You could try django-nonrel: http://django-nonrel.org/ I have never tried 
it myself but from the documentation it seems to keep a lot more of the 
functionality of Django than just using Django without a relational DB.

There are plenty of other Python frameworks. Flask is worth a look.

You may get a better answer if we knew why you are using the file system 
and nosql.
