Re: multilanguage folder names in urls?

[Rohan]

Hi, Here's my solution to what I think is the same requirement:

First of all setup urlpatterns in urls.py to map all the language
variations to the appropriate views. I found this step to be necessary
as:
a) I don't know how to rebuild urlpatterns when the language changes
b) it's probably faster to have urlpatterns static and built for all
languages.

--start code--

# 'stores_uri' is a translatable 'folder' name

for language in settings.LANGUAGES:
translation.activate(language[0])

urlpatterns += patterns('views',
(r'^(?P[a-z]{2})/'+_('stores_uri')+'/$',
'stores'),
(r'^(?P[a-z]{2})/'+_('products_uri')+'/$',
'products'),
)

--end code--

Then in the templates, I build the urls by referring to the
"stores_uri" message id, like so:

--start code--


{% trans "stores"%}

--end code--

I made a seperate message id for the URI with idea that the
translation shouldn't be changed once released (as it will cause a URI
change)

geodjango error

[rohan]

I am following the geodjango tutorial on djangoproject. I have
installed postgresql with postgis. and tested orginfo with GDAL
sucessfully. However, I am getting an error while running syncdb.

Re: How can Selenium see a record that I can't find from a debugger?

[Rohan]

Hi Bryan,

I believe the problem is that selenium and the django testing framework 
are looking up different databases. To run selenium, you would be 
starting the actual server


One solution is to use 'manage.py testserver ' for running 
the selenium tests. This will ensure that the data is populated into the 
testserver, and will be deleted once the server is stopped

Re: Deployment: Apache2, wsgi (Debian squeeze)

[Rohan]

If you change '/django' to '/' in your WSGIScriptAlias directive, then 
everything will be forwarded to django, but apache will no longer check 
in DocumentRoot since all url paths begin with a '/' and will be matched 
by your wsgi alias


This means you would need another way of handling static content that 
doesn't need to be rendered by django. I personally use an nginx proxy 
in front of apache which serves static content directly and forwards 
dynamic requests to apache.


In answer to your question of how you handle the same problem through 
urls.py, you can use the django static files app as explained in 
https://docs.djangoproject.com/en/dev/howto/static-files/


For example, having the following in urls.py

url(r'^media/(?P.*)$', 'django.views.static.serve', 
{'document_root': settings.MEDIA_ROOT,}),


lets django serve requests beginning with '/media' directly if your 
media files are located at MEDIA_ROOT simlar to how apache serves 
content from DocumentRoot. However, as the django documentation 
explains, this is highly inefficient, and NOT recommended for production 
since webservers do a better job of handling static content. As Kenneth 
suggested, setting up a virtual host in apache is an excellent way to 
start off.

I would suggest that you start with trying to understand the concept of
virtual host in Apache. Try to set up a virtual host serving static
content at the start and once you understand that, things will start
falling in place (I am from a similar background from you, and thats how
I did it.

Re: submit parameters to py script

[Rohan]

For a cgi script or a wsgi script, all you need to do is add a script 
alias in your apache conf (if you're using apache). The parameters 
should be available as a a dictionary in both the cases 
(cgi.FieldStorage() and envrion).


Although it would help to know why you want to do this. If you already 
have django up and running, you could just implement the functionality 
of your script as a view function

Re: Getting images to appear in html using Django.

[Rohan]

Hi Jak,
I would suggest removing the "," after MEDIA_ROOT in your settings file 
if it indeed is there. Could you also be a little more specific about 
the problem. Is the rest of the page loading fine? and if it is, do you 
see /media/ being pre-pended to your file name when you see the source 
of your html page? Are you getting a page not found error when you're 
trying to access the image directly ( /media/FAPLogo.jpg) ?


Additionally, are you by chance pointing ADMIN_MEDIA_PREFIX  in your 
settings.py to /media/ as well?

Re: Deployment: Apache2, wsgi (Debian squeeze)

[Rohan]

Hi Matt,
If you do not have static serving enabled in your django application 
mapping to /static/ in urls.py, then the content is being served by Apache.


What is your MaxRequestsPerChild in your apache conf?

One of the reasons production environments use a different web server 
for serving static content is that wsgi applications are blocking 
applications and the server blocks activity until the wsgi request is 
handled. This could affect your performance for concurrent requests if 
you have a single process

I've arrived at something that works:

httpd.conf:

Alias  /static 
/usr/local/django/projectName/static


So everything that's not a template lives under 
/usr/local/django/projectName/static. Is this ok? Does this mean when 
I link to say /static/foo.jpg in a template that foo.jpg is being 
served up by apache directly, ie not handled by wsgi?


I've noticed that the site is slower to load up than before django? Is 
this normal?

How to store multiple instances of a single object in the database

[rohan]

Hi,

I am creating a chemistry database using django's admin interface in
Sqlite3.

The database has a simulations table which has a many to many
relationship with the compounds table.
Each simulation needs to start off with a fixed number of compounds
that it has and each simulation can have 1 or more compounds. suppose
a simulation has water molecule and hcl molecule, it must start off
with 25 water molecules and 10 hcl molecules. Is there anyway in
Django to define this within the database? Please let me know if the
question is not clear and I will post my models here.

Thank you

Django with AJAX, execution of long processes

[Rohan Jain]

Hi!

I have a problem with django and ajax.
I am giving requests from ajax which run a process that takes some
time and has many stages. Is there any way to return the various
stages as responses, so the user does not have to see only the loading
image but can also the current status of the process.

Re: django queryset get only one result for one column pair

[Rohan Jain]

Actually there may be many submissions with a user-problem pair but i
want to list only the last one per user - problem pair.
Like:

let p1 be two problems , u1, u2 be two users and s1,s2 two submissions
by user u1 on problem and s3,s4 by u2.

so i want to get a queryset with only the last submission by u1,u2 on
p1.

Re: django queryset get only one result for one column pair

[Rohan Jain]

My models are defined like this:

class Problem(models.Model):
title = models.CharField('Title', max_length = 100)
question = models.TextField('Question')

class Submission(models.Model):
user = models.ForeignKey(User)
problem = models.ForeignKey(Problem)
solution = models.CharKey()
time = models.DateTimeField('Time', auto_now_add=True)

I want to run a sql command on submission field and get the list of
submissions ordered by submission time and will include only one
result if there are more than one submissions by a same user in one
problem.

Re: Any job queue systems that integrates with Django & allow scheduling jobs by date?

[Rohan Jain]

i think what you need is http://code.google.com/p/django-cron/

Also you may want to check out http://celeryq.org/ if you want to do
parallel processing,
distribute jobs to other computers to ease the web server load.

Re: Object ID is not assigned after calling save() on a new object

[Rohan Jain]

Django assigns an id field to models automatically, so you dont need
to define it seperately. And even if you define it you have to assign
auto_increment = true so that it is automatically filled.

ANN: django-yamlconf 1.1.0

[Michael Rohan]

Hi Folks,

Have release v1.1.0 for django-yamlconf, a module supporting Django
settings via YAML files (searching up the directory hierarchy, e.g., in a
K8s environment, adding a "final" set of settings via "/APPLICATION.yaml",
see the documentation a https://django-yamlconf.readthedocs.io/en/latest/
for more detailed info.  The primary driver was the update to PyYAML load
function to require a Loader kwarg.

Take care,
Michael.

New functionalities expected in Django 2.

[Rohan Purekar]

Is django 2 going to have inbuilt package for creating API's to cater to 
ajax requests and JSON responses for which we use DRF. Another thing which 
was on my mind was If Django 2 will come out with support for Token Auth as 
a default package along with the current session based login.

How to set custom template in Class PasswordResetView

[Rohan Purekar]

I have implemented class based password reset view as instructed in 
django1.11 but the template being used is the default template, I want to 
use a custom template. Where I am stuck is If I have to use a custom 
template then I will have to call get and post functions to return the 
template to be rendered but what do I write in those functions I am not 
getting that part. 

Thanks in advance

Re: sphinx inside

[Michael Rohan]

Hi,

I believe it's probably easiest to simply create the Sphinx html files in 
one of the static directories (probably should add to the top level one if 
you have one, or one of the apps if the docs are app specific) and just let 
the static file handling serve them.  You could use whitenoise to have 
Django serve them (if you want to go that route).

Take care,
Michael.

Re: How can I create a new table without primary key filed?

[Rohan Nagalkar]

Hi, Though its a too old question, but just thought of answering because i 
also got the same issue
One thing you can do is first migrate(syncdb) to bdatabase and then load 
the data.

ANN: django-yamlconf 1.0.0

[Michael Rohan]

Hi Folks,

 

The package Django-yamlconf 1.0.0 has been uploaded to pypi.  There are a 
number of YAML (and other formats) support modules for managing Django 
settings.  The main difference here is:

   1. The directory tree is used to store multiple YAML config files with 
   definitions higher up the tree over-riding definitions lower down (intent 
   being a committed version for development values, production settings being 
   in, e.g., “/var/myapp” or mapped into a container).
   2. The settings that can be adjust is not constrained: simply add a 
   definition to a YAML file loaded and it’s available as a setting (the setup 
   is an import and a load at the end of the settings file)
   3. Can set elements within dictionaries in the settings using a dot’ed 
   notation, e.g., DATABASES.default.NAME: mydb
   4. For debugging purposes, a view is available which can be added to the 
   supported URLs

 

For more information and deeper documentation, see the GitHub page,

 

https://github.com/vmware/django-yamlconf

 

Feedback, bug reports, etc., are welcome.

 

Take care,

Michael.

Django Mysql Bulk_Create Ids

[Rohan Nahata]

How can we make this happen? 
What steps would be needed so that bulk_create ends up returning the ids of 
the items that just got created? I don't want to be machine gunning my db 
with save statements to retrieve ids.

Re: Django SECRET KEY

[Michael Rohan]

Hi Folks,

An extension of this local file is the project django-yamlconf (See
https://django-yamlconf.readthedocs.io/en/latest/).  It allows general
over-ride of settings.  It is my project (full disclosure).

Take care,
Michael.

ANN: django-yamlconf v1.4.0 is available

[Michael Rohan]

Hi Folks,

Have released v1.4.0 for django-yamlconf, a module supporting Django
settings via YAML files (searching up the directory hierarchy, e.g., in a
K8s environment, adding a "final" set of settings via "/APPLICATION.yaml",
see the documentation a https://django-yamlconf.readthedocs.io/en/latest/
for more detailed info.

The updates for the this release are:

- Added support for JSON encoded environment values if decorated with
":jsonenv".  If JSON decoding fails (invalid JSON string), the value is
used as is.  This allows the definition of more complex values via the
environment, list, dictionaries, etc.  This can be used in K8s
environments, e.g., Concourse (for me).

- Added a `CODE-OF-CONDUCT` file for contributors.

Take care,
Michael

Re: How to best secure environment variables (secret key, passwords etc.) stored in .yml files?

[Michael Rohan]

Hi,

Just fyi, it was, in part, to solve this problem that I implemented the
django-yamlconf module:

https://django-yamlconf.readthedocs.io/en/latest/

While getting the data into either a private yaml file or env variable in
the container isn't addressed, it does allow injecting the values into the
Django app without modifying the committed sources.

Take care,
Michael.

ANN: django-yamlconf v1.2.0 is available

[Michael Rohan]

 Hi Folks,

Have release v1.2.0 for django-yamlconf, a module supporting Django
settings via YAML files (searching up the directory hierarchy, e.g., in a
K8s environment, adding a "final" set of settings via "/APPLICATION.yaml",
see the documentation a https://django-yamlconf.readthedocs.io/en/latest/
for more detailed info.

The updates for the this release are:

- Tagged with ``v1.2.0``.
- Updates to support Django 3.0: Simply use "`six`" instead of the
  support "`django.utils.six`" package and use "`render`" instead of
  "`render_to_response`".
- `ycsysfiles` should generate executable files if the source template
  file is executable.
- Ensure the absolute path is used when searching for YAML control
  files.  This issue is seen when running Django apps under uWSGI
  control.
- Added the built-in attribute ``CPU_COUNT`` (primarily for use in uWSGI
  ini files) giving the number of available CPUs.

Take care,
Michael.
