Re: Django learning

[Tomás Garzón Hervás]

Hi, you have to indicate where is the settings file to django. You can use 
the environment variable DJANGO_SETTINGS_MODULE.
 More info:

The script is designed to handle advanced cases (inherited models, proxy

Hi Arthur,

The error message is about "timezone-aware times", not "timezone-aware 
datetimes". Your code must be creating a timezone-aware time object 
somewhere. This is quite a pathological type and it isn't supported by 
Django.

This limitation is briefly mentioned at the bottom of this 
section: 
https://docs.djangoproject.com/en/dev/topics/i18n/timezones/#naive-and-aware-datetime-objects

Hi James,

Since you're talking about USE_TZ, I suppose you're using Django 1.4. But 
the code you're quoting no longer exists in that version:
https://github.com/django/django/commit/9b1cb755a28f020e27d4268c214b25315d4de42e#diff-3
 

That said, this appears to be a bug in Django. I've created a ticket:

custom db field as filter in admin

[Bram de Jong]

Hello all,


I have a custom DB field: a version string like "1.0.5rc3" which is
actually stored as an int in the db.
After fidling around a bit I managed to make the field so that
everything you would think should work works. It looks like a version
string everywhere, I can input it as a version string everywhere.

However, when I turn this field into a filter in the admin, instead of
seeing the filter-versions as my string (i.e. "1.0.5rc3") I see it as
the underlying database type (i.e.1301)

I implemented __unicode__ and __str__ on my object, but no luck either!

I suspected there is another code path that doesn't call to_python
properly, but let's rule out it's not the same as my issue:
Is this field a foreign key for the model that's being displayed?

It isn't.

Where should I be digging to figure out the code path being called?

Additionally clicking the filter will make things crash because I'm
getting a string which is "1301" if I do.

Just to rule out simple stupidity on my part, here's the model field
and form field I'm using.

Re: Time zone (Django 1.4) questions

[Klaas van Schelven]

Hi Aymeric,

Thanks for the answers!

I've decided to postpone the migration on one of our bigger projects
to USE_TZ = True until after I have some experience with proper time
zone handling in a greenfield project. This won't last forever,
though, and once I get to it I'll report back with any globally-useful
results.

I imagine some of the answers to my questions will be worked into the
docs at some point. If I can help out at that point in time I
certainly will.

ciao,
Klaas

You should not be getting integer instances in get_prep_lookup(). That's
your initial debugging point. I have a similar field (integer rep in
database and string rep in python) and I'll check if I can reproduce
your case, once I get back to that machine.

To get this bug[1] traced down, I created a logger in settings.py and
inserted logging statements and assert(1==2) in the code paths. But
there are some __magic__ methods involved that don't backtrace well, so
that's where logging comes in. If it's the same root cause as my bug,
implement value_from_object on your field and call to_python on the
value argument.

direct_to_template (with same name template) in a multi-app project

[Joris A]

Hello all,

I am developping a second app in the same project and want to use a
simple.direct_to_template view.

Both of my app require a login from user, thus I have in both app a
login page.
With a lot of creativity I named both of my login pages and index
pages ; login and index, with the corresponding templates login.html
and index.html.

I have a main urls.py file which include the urls of the two other
apps like this :
urlpatterns += patterns('',
url(r'^app1/', include('app1.urls')),
url(r'^app2/', include('app2.urls')),
)

In both app specific urls.py I have the following (simplified) :
urlpatterns = patterns('app1.views',
   (r'^$', 'index')
   )
urlpatterns += patterns('',
   (r'^login', 'django.views.generic.simple.direct_to_template',
{'template': 'login.html'}),
)

My problem is that the first app mentioned in settings "installed
apps" seem to have precedence in the template loading. It's like the
app tree is not taken into account in {'template': 'login.html'}. Thus
because they have the same name, I am always using the template of the
first app declared in installed apps.

If I rename the template index_app1.html and index_app2.html it works
as expected. So this is an option but...

Is there a way to tell which template to use?

Thanks in advance for your help!

Re: Import error

Dear Marcin,

I do not understand.
I think I have done everything right and I am trying to find
the source of the error where if there is someone who has
experienced it they might be knowing where it is coming from..

Dear Emily,

Do you expect us to already have a copy of your code? If not, we need to
have a short, self-contained, and correct example demonstrating your issue.

How to render a modeladmin dynamically?

[Thomas Weholt]

In a view, I need to get a modeladmin for a model provided
dynamically, change some of the attributes  of the modeladmin ( add an
aggregated field to the queryset, order the queryset by that field and
add a column for that new field in the list_display of the modeladmin
) and render the request using a custom template extending the normal
change_list template. I cannot add these things to the modeladmin of
the models in question, it has to be done at runtime.

Hi Emily,

Here is a really good article (written by the very people who contribute to
this list) on how to ask questions on the mailing list:

https://code.djangoproject.com/wiki/UsingTheMailingList

It tells you what you can do to try and resolve the issue yourself, and
what sort of information you need to provide so we can assist.

Where I am wrong in loading static files ?

[surya]

This is my project folder hierarchy:

project \
   project \ 
  __init__.py
  settings.py
  urls.py
  views.py
  ... etc
   templates \
   css \
index_css.css

   media \ 
 logo.png

   templates \ 
 home.html
   manage.py


So, these are the settings I made in "settings.py"

currDir = os.path.dirname(__file__)
templateDir_media = 
os.path.join(os.path.join(os.path.split(currDir)[0],"Templates"), "media")
templateDir_css = 
os.path.join(os.path.join(os.path.split(currDir)[0],"Templates"), "css")

STATICFILES_DIRS = (
templateDir_media,
templateDir_css,
"d:/code/projects-dev/readdme/"
)
## I JUST ADDED THOSE /MEDIA AND /CSS DIR IN IT

The HTML source file contains:

Image URL:  src="../media/logo.png"
CSS URL : href="../css/twoColFixLtHdr.css"


So, when I am loading the page, I am unable to find the logo and CSS 
 settings.. 

Where I am going wrong and how should I fix it?

Hey Garbiel,

I actually figured out the issue on my end. From what I gather, uWSGI
doesn't handle small POST data sizes well. I had to change a couple of
uWSGI configuration parameters (as seen on Stackoverflow).
As far as I can tell -- my stuff is all good now, both in the Fluid and
fixed-size layouts.

If you need any help debugging yours, let me know! And thanks for the
feedback.

Re: Import error

[Emily]

so your point is that I should post my code.
When I did that some time, I was told that
the people who were trying to help me did not
want to know what is in my code so I should just
explain what I want them to help me with.
But thank you any way, you point has been driven home.

You're supposed to load the shell with `./manage.py shell` rather than 
going directly into Python. That is explained in the tutorial.

Re: Import error

[Kurtis Mullins]

Hey emily,

I think the other guys were just wanting to see your import statement
that's broken. It should be something along these lines if you want to give
it a try:

from myproject.myapp.myhelpers import random_password

Of course you'd substitute your project name, the application name, and
then the python file that your "random_password" function/class is saved in.

Let me know if you need any more help!

Good luck!

Taking advantage of multiple cores

[Jonathan Hayward]

Will a slightly older version of Pinax, installed on top of a newer version
of Django, take advantage (or be configurable to take advantage) of
multiple cores?

In other words, if one request is rendering and another request comes in
while the first is rendering, will Django or Pinax offload the second
request to another core?

If this isn't the default, can it be enabled, and are there race conditions
or other risks?

exactly.

specifically, Django is by itself, a shared-nothing library.  that
means that you can run many instances of it.  not only on several
cores but also on many different hosts.

Just be sure that anything that works 'outside' the request/response
cycle is is managed in a properly shared storage.  mostly the
database, cache (memcached/Redis), queue manager...

stay clear from in-process memory storage (global variables, thread
local storage, etc) and your app will be trivially scalable.  your
bottleneck would likely be the shared data, but any good RDMS go far
on big machines, especially if you handle right the cache and queue
layers.

Take random_password outside of the Helpers class and you should be OK.  On the 
import statement you need to refer to a 'top level object' within the imported 
file.  The only top level object you have is the class  Helpers - which it 
doens't look like you really need.

You probably have a race condition. You should use the built-in 
`get_or_create` manager method, which helps to minimize that sort of thing 
(it's not perfect, but it's better than coding it yourself).

This will give you auto-completion. So if you started typing something like
"models." and hit tab, it'd show you all of the available methods and
classes you can use.

Re: Import error

[Kurtis Mullins]

+1 on pulling the "random_password()" method out of the Class and setting
it up as a module object.
I'd still suggest using this sort of an import statement on it, though:

from myproject.myapp.helpers import random_password

Where in this example you'd substitute your Project name with "myproject",
the app name with "myapp" and the this particular python file with
"helpers.py".

Re: Duplicate rows with same key in DB?

[Kurtis Mullins]

You could also put a unique_together statement in your Model. If you do
this, you'll need to update your database as well to enforce the constraint
at the database level.

Re: Taking advantage of multiple cores

[Kurtis Mullins]

Basically, you just need to run multiple instances of your Django
web-application. I've never used Apache for this (I'm an Nginx + uWSGI fan,
myself) but you'd just run multiple worker processes and your WSGI handler
should "balance" between them.

Like the others mentioned, make sure to use a common cache like Memcache.

Re: Where I am wrong in loading static files ?

[Kurtis Mullins]

Here's a vaguely similar post:
http://stackoverflow.com/questions/6409920/django-static-files-from-app-directories

Like one of the respondents recommended, try adding a "print
str(STATICFILES_DIRS)" in your settings.py and then run "runserver" so you
can see what actual directories are being included.

Re: Import error

[Emily]

Kurtis, Adrian and Daniel,

thank you so much for your help, it actually worked
I have programmed in java 70% of my life

Now I want to send sms to my users when they sign up
in the website. There is some package I have seen which looks
like it is from an email to the phone. Does it work with messages
from a website to a phone...

Re: Select * from users,country where country.id = users.id in Django using amin.contrib

[Kurtis Mullins]

Hey,

Here's some sample code just from reading what you've provided.

from django.contrib.auth.models import User
users_in_country = User.objects.filter(cUser__name="some_country_name")
if bool(users_in_country): # Check to make sure there's at least one User
in the Country
for user in users:
goal = GoalsinCountry.objects.create(gCountry=user.cUsers,
name="Some Name", descr="Some Description")
goal.save() # Possibly not needed, I'd have to run the code to check

With that said, I'd recommend changing the naming conventions of your Model
fields. For example:

User
- name
- country

Goals
- name
- description
- country

Country
- name

Sorry, wanted to mention a small fix on what I imagine would be better
naming conventions (just so your code is clearer and easier to query)

Goals
- name # Is this the user's name? Then why not just make this a foreign key
to a User? so maybe user = models.ForeignKey(User)

Also, some docs on querying django models:

Re: Where I am wrong in loading static files ?

For your URLs, use {{ STATIC_URL }}/css/index_css.css (or maybe {{
STATIC_URL }}/app_name/css/index_css.css -- I've never tried this approach
before)

You're not using staticfiles, because they will always result in
absolute path references. Try starting with the documentation and let us
know what you don't understand about it:
https://docs.djangoproject.com/en/1.4/ref/contrib/staticfiles/

Re: Where I am wrong in loading static files ?

 ## I JUST ADDED THOSE /MEDIA AND /CSS DIR IN IT

 The HTML source file contains:

 Image URL:  src="../media/logo.png"
 CSS URL : href="../css/twoColFixLtHdr.**css"


 So, when I am loading the page, I am unable to find the logo and CSS

 Where I am going wrong and how should I fix it?

Re: Installing Django @ Shared Host

De ninguna manera, lo mejor es que veas si el hosting soporta django, sino 
deberias cambiar de proveedor.

403 error with SAMEORIGIN in header

[Mike]

I developing a mac desktop app and I'm just making the first steps to add a 
feature that will connect to a Django server.  I have the Django project 
running on the development server and the app running on the same machine. 
 When I try to call a Django project view from the app, on 127.0.0.1:8000, 
Django replies with a 403 error and this header:

*"Content-Type" = "text/html";*

*Date = "Fri, 22 Jun 2012 16:43:27 GMT";*

*Server = "WSGIServer/0.1 Python/2.7.1";*

*"X-Frame-Options" = SAMEORIGIN;*

This seems to have something to do with clickjacking protection but I'm not 
doing anything with iframes.  Is there any other reason why Django would 
return this error?

Re: Installing Django @ Shared Host

[Kurtis Mullins]

I recommend building your application locally (on your own computer). You
can follow the tutorial and use Django's built in server for testing.

Once your application is ready to go live, then find a Django-Friendly
host. They're not too expensive.

I wouldn't recommend getting a django-friendly host before you build your
application because you may, or may not, decide that Django is right for
you.

Good luck!

Re: runserver cache my template files

Are you using a non-temorary caching mechanism like Memcache or DB Caching?
If so, do you have caching directives in your templates?

Internationalization Issues

[Ricardo Jacas]

Hi Everyone,
I'm having a lot of trouble with i18n. My templates don't display all the
translations (i've already checked for the "fuzzy" tag).
I have no idea what could it be, any thoughts? Anything may help, i've been
reading forums for hours.

Installing via Tutorial Part 2 / MacOSX / Can't create a superuser due to locale() problem.

[Bill Torcaso]

Hi,
I'm working through the tutorail.  Part 1 was fine, and part 2 shows me the 
site with the light blue background.  I proceed to make my first app, 
'djangotest'.

   1. I run django-admin.py and get a project
   2. I edit settings.py to select sqlite3, and put in an absolute path to 
   a sqlite db file.  I leave 'America/Chicago' unchanged.  the same error 
   happens if I change it to my timezone in EST.
   3. When I run syncdb, I get this error.  I look in the source and it has 
   something to do with 'locale' and a tuple of (None, None).  Please help.

Re: Installing via Tutorial Part 2 / MacOSX / Can't create a superuser due to locale() problem.

[Kurtis Mullins]

Did you get an opportunity to type anything after "yes"? Or did it
just blow up at that point?

Based on the traceback, it looks like it is having trouble getting
your system's default username. I've never really noticed that it has
that functionality before but I wonder if there's something "weird"
about your System's configuration?

Which version of Django are you using?

To by-pass this (until you get the real problem worked out) give this a shot:

python manage.py shell # This will open up a terminal-shell in your
Django Environment
from django.contrib.auth.models import User # Import the User Model so
we can create a new user
user = User.objects.create_user(username='someusername',
password='somepassword', is_superuser=True) # Create the new User
(Remember these credentials)
user.save() # Save the User
exit() # Exit the Python Shell

And you should be all good to go.

Race and Locking? was Re: Duplicate rows with same key in DB?

[ydjango]

Thank you, I also believe it is Race condition. I do not want to use 
get_or_create as I like to have control over DB writes and updates. I will 
try Unique_together and catch the integrity error exception as Kurtis 
suggested or check again before doing save().

or just thinking aloud, Is there a way to acquire a lock which can 
serialize any other requests which have same "a" and "b" values?

Send message to SMS Gateway

[Setiaman]

Hi,

I want to create a web app to send the message to SMS Gateway.
Try to google the suggested way is to use SMPP protocol.
But I can't find any easy package to send message thru SMPP.

Can any body give a pointer?


Rgrds,
Setiaman
