sites framework + gunicorn
Hi, I'm trying to run multiples sites using the sites-framework, and gunicorn. I'm using the same project, same databases, only I try to use different settings.py files with different names. The idea is that in each gunicorn instance I set the DJANGO_SETTINGS_MODULE to a different settings.py file, and hopefully get the corrrect result. Unforutunately, it doesn't seem to matter what I set DJANGO_SETTINGS_MODULE to, no matter what it always points to settings.py Now I've run gunicorn using manage.py and explicitly pointing to the settings.py file I want, and maybe that's the solution I will end up using, but I'd like to be able to set things using gunicorn configuration files. So my question is this, does anyone have an idea what my problem is, and what the solution is?

Re: sites framework + gunicorn
what I mean is that each supervisor thread calls a separate gunicorn process. Sorry I'm getting the terms confused. Anyway, I tried it, but I'm still having trouble. Here is my supervisor.conf [program:gunicorn-blog-HE-development] directory=/var/www/blog.development/private/blog command=/var/www/blog.development/private/blog/manage.py run_gunicorn 127.0.0.1:8091 --settings=settingsheb user=www-data autostart=true autorestart=unexpected redirect_stderr=True exitcodes=1 Now I have no problems if I run this a command in the terminal, e.g. "python manage.py ...", however, I also set the python path beforehand, and I don't see how to do that it supervisor. I know I can set an environment variable, for example environment=PYTHONPATH='/ path/to/apps', but what if my python path looks like this: PYTHONPATH='/path/to/apps1':'/other/path/to/apps2' This would be a LOT simpler if I could get gunicorn to run properly, anyone have any suggestions? -ron On Mar 3, 3:19 am, Shawn Milochik wrote: > What do you mean by 'gunicorn instance' here? > > > The idea is that in each gunicorn instance I set the > > DJANGO_SETTINGS_MODULE to a different settings.py file, and hopefully > > get the corrrect result. > > In any case, I highly recommend you just use supervisord[1] for this > and put the path to the settings files in your supervisor config. > > Here's an example of what your supervisord config might look like: > > [program:my_site_1] > command=/home/username/projects/awesome_site/manage.py run_gunicorn > 127.0.0.1:8000 --settings=projects.site1_settings > > [program:my_site_2] > command=/home/username/projects/awesome_site/manage.py run_gunicorn > 127.0.0.1:8100 --settings=projects.site2_settings > > 1:http://supervisord.org/ > > Shawn -- You received this message because you are subscribed to the Google Groups "Django users" group.

rewrite rules
I have to make a blog application in multiple languages, to do this, I decided to use zinnia and create to separate urls blogfrench.com and blog.com (this is an example). I also used the multisite ability of django to have a single admin interface for both blogs. It works great, now I have a non-pythonic problem. I want both blogs to be read with the same url: that is, instead of blog.com blogfrench.com I want blog.com/en/weblog blog.com/fre/weblog So. Does anyone know where I can find help in creating rewrite rules? I have no idea how to do it (btw, I'm using nginx if that helps) -- You received this message because you are subscribed to the Google Groups "Django users" group.

It is in the docs, although it's probably not immediately clear for people not coming from a python background. http://docs.djangoproject.com/en/dev/topics/db/queries/#retrieving-specific-objects-with-filters **kwargs means keyword arguments (note that it's plural).

You don't have to pull all() if you only need a sub
from django.db.models import Q
messages = Message.objects.filter(
Q(recepient='Alle') | Q(recepient=department)).order_by('-created')[:2]
or if you don't want to use Q:
messages = Message.objects.filter(
recepient__in=['Alle', department]).order_by('-created')[:2]

Search for "generic views" in the documentation, you might be
interested in the date based views.

You probably already know this: QuerySets are lazy:
http://docs.djangoproject.com/en/dev/topics/db/queries/#id3
Though I'm not too sure with the slice filter. If anyone's interested
to find out, they could inspect the generated SQL queries to check.
I only use the slice filter if it's not possible for me to know in the
view beforehand how I'm going to slice my list, or if I know for sure
the size of my list is relatively small.

You can modify the admin templates, particularly the change list template (change_list.html), to *show* the subtotal. See here for more info re: modifying the admin templates: http://docs.djangoproject.com/en/dev/ref/contrib/admin/#overriding-admin-templates *Obtaining* the subtotal is another issue. One way is to use Javascript that is (conditionally) loaded from the template. There are other possibilities: custom model manager method, custom SQL that includes SUM(...) as a field, and maybe custom ModelAdmin (I'm not too sure about this though). Once you get the subtotal you can display it using custom admin template. Hope that gives you a starting point.

I just did something similar (the popup part not the autocomplete
part), maybe it could give you some ideas. I ended up modifying the js
(copied into a new file and use that instead of
RelatedObjectLookups.js). Basically I modified the dismiss function so
that it can accept and call a callback function, something like:
function dismiss(window, callback) {
...
callback()
win.close()
}
and then in the view I added this:
return HttpResponse("""
opener.dismissEditPopup(window, function(){
opener.update_info()
});
""")
and I can define update_info() in the opener template to do whatever's
necessary.
This is similar to what django's admin is doing (see
django/contrib/admin/options.py around line 427 under response_add()).
Hope I'm still making sense. It's 1am here.

That exception will always be raised if the view is called via GET
method instead of POST.
If you're sending it via POST, then the information you provided was
not sufficient. We need to see template code that renders the form (or
the html form if you're not using templates) and probably the form as
well.

model instance version numbering, or concurrent model editing
G'day all, Let say I have a wiki-like Django app. I wanted to allow many people edit a wiki page without any locking, yet have the system prevent two people saving page updates at almost the same time (one of the updates would be lost, overwritten by the other one). This is what I have in mind. Add a version field to the WikiPage model which is automatically incremented on every update. The system should not allow saving an existing page with version (in db) >= version (in data to be saved). This is probably done in save(). I've tried overriding the models's save() method, but I'm always stuck at how to get the guaranteed-most-recent version number (lock the row/table?) from the db (as opposed to self.version, which could already be stale by the time save() is called). My questions are: * Is my approach reasonable? (or Have I missed a more obvious/easier way?) * Can this be achieved in Django? If so, any ideas how? * Should this be done in Django, or better implemented on the database level as ON UPDATE trigger(s)? I checked django-wiki app in google code, but it doesn't seem to have this feature. I wanted to keep my question focused on one particular issue first, but if the bigger picture makes any difference: my WikiPage model is actually an abstract model, and I wanted to provide this feature for all of its subclasses. I would appreciate any help. Cheers, Ronny --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

I use the following method in one of my projects:
def feetinch_to_cm(length):
"""convert US style (feet-inch) length to metric (cm)"""
if length == u'' or length is None:
return None
m = re.match(r'(?P\d+)[\'`](
*(?P\d+)(?P.)?("|\'\'))?', length)
if m is None:
raise Exception("unable to parse length: %s" % length,)
feet = int(m.group('feet'))
inch = int(m.group('inch') or 0)
half = int(m.group('half') == u'\xbd')
return (30.48 * feet) + (2.54 * inch) + (1.27 * half)
I save the length in centimeters in database, then I can reformat it
as needed in the template or admin using a custom filter.

I wouldn't do that, it doesn't make sense to me.
Only this is needed in models.py:
class FooBar(models.Model):
length_in_cm = models.FloatField(default=0)
Then somewhere else (e.g. views.py or others):
length_us = '5\'2"'
foo = FooBar()
foo.length_in_cm = feetinch_to_cm(length_us)
foo.save()
Alternatively, if you want FooBar to understand and support the
conversion you could create a length_in_feetinch property that will
automatically do the conversion to cm while keeping only the
length_in_cm in the database, have a look at
http://adam.gomaa.us/blog/the-python-property-builtin/ for an example.

Right. I can see how this is useful for creating a generic form template.
In that case, I'd probably write a custom tag to do the job, probably
something along the line of:
{% if_widget_select field %}
This is something similar that I had done previously:
from djblets.util.decorators import blocktag
register = Library()
@register.tag
@blocktag
def if_is_select_field(context, nodelist, field):
if isinstance(field, forms.MultipleChoiceField):
return nodelist.render(context)
else:
return ''
You can find djblets tag helpers here: http://www.chipx86.com/blog/?p=245

Ronny

I don't think there's a standard, since Django is not a CMS (you build your CMS *with* Django), and therefore it doesn't provide any CMS-specific things like sidebars, widgets, boxes, or whatever it is called. However, Django templates supports inheritance and a way to include other templates that should make it easier: http://docs.djangoproject.com/en/dev/topics/templates/#id1 http://docs.djangoproject.com/en/dev/ref/templates/builtins/#include For static blocks, there's also a 3rd party project called django-chunks that you might want to take a look at.

For our last project (not Django, unfortunately), we created a directory that holds SQL changes files. The files were named "from-1234.sql" where 1234 is the current svn revision when the file was created. Everytime we made a change to the database model, we modified the main sql file (equivalent to models.py in django), then we also created an SQL change file containing all the changes (alter, drop, etc.), then we ran the SQL change file to actually modify the database instead of modifying the database directly. Other developers would need to pay attention for additions in the SQL changes directory and update their database accordingly whenever there's a new file there.

It's python kwargs (keyword arguments). You can do this:

model.objects.filter(**dictionary)

Django's templating is not restricted to HTML only. You can do
something like this in the view:
render_to_response('style.css', {'bgcol': '#fff', })
Then in style.css you can have:
background-color: {{ bgcol }}
You might need to set the correct mime type when serving non-html
files. Please check the docs.

Another way (which I personally prefer because it's more explicit and clear), is to do it in the view. Don't show the author field in the form, because we want to automatically add it before saving. def add_item(request): ... item.author = request.user item.save() The syntax might not be correct, but you get the idea.

where to run extra SQL when "manage.py reset appname" is run
hi! i've discovered django a few days ago and i must say it looks very useful and decided to use it for my latest project. i might ask some simple questions cause this is new to me, but am going over the documentation (and google) before asking. anyways done to business: i'd like to use some triggers to increment and decrement fields in the db. i've written them up but would like to know if there is somewhere to run them when i reset (or the initial syncdb on) an app with manage.py? i saw that django.core.management.get_sql_all() collects all the SQL to be run, but there doesn't seem to be a place for other SQL (like trigger declerations). thanks, ronny --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: problem with ImageField does not show me the picture on a template
Thanks a lot.
I do the following steps:
aggregate an alias to the virtual host of my site:
Alias /media /var/www/fourweb/media/
and modified:
settings.MEDIA_ROOT = '/var/www/fourweb/media/'
settings.MEDIA_URL = 'http://fourweb.com/media/'
it works!.
Cheers
Ronny

Re: View pictures from the template via models.FilePathField
Hi Federico,
Maby is better idea you use the models.ImageField(upload_to= path)
ie:
locandina = models.ImageField(upload_to= path)
then in the template you can get the path:
{{ object.locandina.url }}
Also, you need to read some about configuration on settings.MEDIA_ROOT and
settings.MEDIA_URL, for use the imageField.
Regards,
Ronny
