Re: new user having trouble connecting django to postgres with psycopg2

2011-01-08 Thread Jeff Tchang 
Can you try logging into the database and running:

SELECT * FROM pg_timezone_names;

Maybe try picking something from that list?

Slightly off topic, but:

"Better" isn't the issue. Mod_python has been deprecated by it's
authors. It is, for all practical intents and purposes, a dead
project. If you have a RHEL support contract, Redhat will continue to
provide support, but I'd be surprised if that support extended much
beyond critical security updates. If you are starting a new project,
you would be well advised to look at mod_wsgi, or another deployment
option.

it's not entirely clear to me what it is you want to see logged.
Django's decision to load or not load a page is essentially just "just
the Regex pattern match", and success is logged as a page load in your
web server access log.

The version of Django currently in development (soon to be 1.3) has
some additional logging, but doesn't give any particular insight into
the URL loading process. Django Debug Toolbar can also give some
visibility to internals.

templating best practices in django

2011-01-08 Thread Mo Mughrabi 
Hi,

I'm wondering what would be the best practice for templating in django. I
plan on having a single theme in which heads and footers will almost be the
same across my project,

1. Should I great an app only for this purpose, in the sense, an app will
host a header and footer functions (methods) along with their views. Is that
the best practice?

2. my second question, if I am going to host a header somewhere centered. Is
it possible that I include or exclude certain css or js from the main
header?

3. Is there a django module that help organizing my js and css in a way?


4. last, what is django_compressor used for, I don't get the idea, If am
going to specify the paths to my js. Why does it combine them all in a
single file? does that make the loading faster?

thanks,

Re: Filtering related objects in template

2011-01-08 Thread +shaun 
>From Stackoverflow - How do I perform query filtering in django 
>templates
:

You can't do this, which is by design. The Django framework authors intended 
a strict separation of presentation code from data logic. Filtering models 
is data logic, and outputting HTML is presentation logic.

So you have several options. The easiest is to do the filtering, then pass 
the result to render_to_response. Or you could write a method in your model 
so that you can say {% for object in data.filtered_set %}. Finally, you 
could write your own template tag, although in this specific case I would 
advise against that.

It is possible. Google for django dynamic forms. The same techniques
can be used for model forms, but you'll have to decide what to do with
the extra fields.

Re: Debugging Deeper Into Django

for custom logging you can always your python logging module, which is just
like
log4j.

Also if you need any specifics regarding db queries etc. you can try out.
Django Debug Toolbar:
https://github.com/robhudson/django-debug-toolbar

Hope it helps.

Translation files are not generated

2011-01-08 Thread Roel Veldhuizen 
When I run "manage.py makemessages -l en" a LC_MESSAGES dir is created for
the language "en" but no files are created.

One of the files that should contain a translation looks like:

{% load i18n %}

{% trans "Profile" %}

In the settings the USE_I18N is set to true and added
'django.middleware.locale.LocaleMiddleware', to the middleware classes. The
templates are shown when i enter the address of the django server so i
conclude that the template directory is set correct.

Thanks in advance

Creating a image gallery form model

2011-01-08 Thread Simon W 
Hi,

I have a 'project' model. Each project can have a gallery (im using the
photologue-app as model).

Now, when I want to let my users edit his project I want to show him all the
photos in the gallery and for each photo he can tick a "Remove"-checkbox
and/or check a radio button that says "Use as image cover".

I guess I need to make a custom form/widget model but Im not quite sure how
to approach it (first time I user forms in Django) but I'd like it to
something like this in the html template:

{% for photofield in form.gallery %}
   {{ photofield.radio_button }} Use as image cover
   {{ photofield.remove_checkbox }} Remove image
   
{% endfor %}


Could you tell me what's the best practice to achieve this?

Cheers!

You can try django-autoslug for your own code. Existing code can be

They are really both, see django-registration, djangobb, pinax, and many other 
django-apps (search google code and github).

This is really a question best left upto you to answer. Looking at existing 
apps, some are small providing specific functionality (django-email-
notifiation iirc is another), others really huge providing a whole slew of 
things (see djangobb and pinax). Others have made apps that just hold template 
tags, to one app for the whole site (which most new django developers do).

My suggestion to you is to build it the way that makes it easy to maintain the 
site, for you and developers after you. If some functionality that you come up 
with can be of use to others, then it's worthwhile to make it it's own app and 
release it into the wild via your fav license.

Hi,

I've been using transmeta for a big project, I had to slightly adapt it to
suit my needs but it works well and I found it an elegant solution.

http://code.google.com/p/django-transmeta/

some migration/maintenance commands are also available within the lib.

Re: i18n django models

2011-01-08 Thread Mo Mughrabi 
This is not exactly what I need.

this library is not done as per the common best practices for i18nlizing
data.

All you have to do is declare an object (field) as an i18n field and the
engine takes care of the rest. This example you can see in java struct and
php symphony, when executing the equivalent for syncdb it will generate an
additional table which holds the i18n languages instead of creating columns
with prefixes and suffixes.

Having columns mapped to a specific language means modifying your table in
the future if you need additional languages. Meanwhile, if creating a one to
many relation with a specific table that holds only the variable in
different languages means you can add as many language support as you need,

Plus, when I went through polyglot it does override a lot
of crucial functions, adding up such plugin into a critical
production environment can be risky with very little information about it.


Any other solutions?

Re: ImproperlyConfigured: 'SentAdmin.fields' refers to field 'dateSent' that is missing from the form.

2011-01-08 Thread gintare 
I did not understand what was the a reason, but i changed order of
items in admin.py fields to be similar to items order in the model.
Maybe mistake was some mistyping. Anyway error disappeared.

Re: A few beginner questions

2011-01-08 Thread Mike Thon 
I've had this question too, when I'm designing a project.  So far, I have 
dumped all of my own code into the one app that I create for the project and 
then add external apps that can be found on the internet to extend my 
project's functionality.  For example, I needed to download articles from 
RSS feeds so I added feedjack to my project.  I don't use any of that app's 
templates or views, but I use the admin interface to manage the feeds, and I 
access the model objects from my own app.  I also use the included command 
line script to update the feeds. For the next project I start, I will think 
about the features that I plan, and whether or not those features could ever 
be reused in some other project.  If so, then I'll try to put those features 
into separate apps.  I believe there are some additional steps to take to 
make an app reusable outside of the project in which it is created.

Re: A few beginner questions

2011-01-08 Thread Ondřej Mirtes 
Thank you all for your responses.

I have one more question - what is the purpose of "apps" in
"projects" (when I create new app in a project via manage.py
startapp)? Are they something like sections of a web (articles, forum,
user administration?) or are they rather something like modules,
reusable across projects? How big should be an app?

How should I solve typical scenario when my site consists of a small
frontend presentation and a complex API service?

Thanks.
