Change the "Location" to "/". Also note that it's a bad idea to keep your Django code and templates under your DocumentRoot. Apart from anything else, it's a potential security hole - if a misconfigured Apache can serve your templates directly, it could also do so with your settings file containing your db credentials. Put it all somewhere else - it just needs to be on your PythonPath, which you're already modifying in the configuration. -- DR. -- You received this message because you are subscribed to the Google Groups "Django users" group.

I don't know about the specifics of your particular issues, but to
send HTML emails:
Create an instance of django.core.mail.EmailMultiAlternatives, passing
in your subject, text version of the email, from address, list of
recipients. Render your HTML version of the email, and attach it to
the email, and then send it.
eg:
from django.core.mail import EmailMultiAlternatives
msg = EmailMultiAlternatives('Subject', 'This is the text version',
'f...@address.com', [ 'recipie...@address.com',])
html_version = ...
msg.attach_alternative(html_version, 'text/html')
msg.send()
There are lots of 'gotchas' when sending HTML email. Don't expect
externally referenced resources to be available, don't expect styles
to work correctly in all UAs, don't expect any JS to work.
Cheers
Tom

Query help
Hi people,
Given this:
class Category(models.Model):
name = models.CharField()
parent = models.ForeignKey('self', blank=True, null=True)
tree_path = models.CharField() # //...///
class Item(models.Model):
name = models.CharField()
categories = models.ManyToManyField(Category)
I need a Category queryset, with each category annotated with a count of items
which have categories whose tree_path starts with the tree_path of the current
category, and with categories for which this count is 0 filtered out.
In case that wasn't clear - I need an efficient way to do this:
for category in Category.objects.all():
category.num_items =
Item.objects.filter(categories__tree_path__startswith=category.tree_path).count()
if category.num_items > 0:
yield category
Suggestions?
TIA, Itai

Django: How to get field value dynamically using custom template tags?
I recently got a problem where I need to get field's value
automatically using templatetags.The idea follows which mentioned in
the book "Practical Django Project 2nd Edition", but the book version
is getting a list of objects where I want to get only a object's
value. I want to get the site settings (Title, Tagline etc.) and pass
in the template dynamically so that I don't have to write the code
again to get each field's value.
Here is what I have done so far.
*Define an admin.py for the model (not included here because it's not
important)*
*Defined a model:*
from django.db import models
from django.contrib.sites.models import Site
class Naming(models.Model):
title = models.CharField(max_length=250)
site_id = models.ForeignKey(Site)
tagline = models.CharField(max_length=250)
description = models.TextField(blank=True)
def __unicode__(self):
return self.title
*Defined a template tag file, the commented line is where I get stuck*
from django.db.models import get_model
from django.contrib.sites.models import Site
from django import template
def do_site_att(parser, token):
bits = token.split_contents()
if len(bits) != 5:
raise template.TemplateSyntaxError("'get_site_att' tag takes
exactly four arguments")
model_args = bits[1].split('.')
if len(model_args) != 2:
raise template.TemplateSyntaxError("First argument to
'get_site_att' must be an 'application name'.'model name' string.")
model = get_model(*model_args)
if model is None:
raise template.TemplateSyntaxError("'get_site_att' tag got an
invalid model: %s." % bits[1])
return ContentNode(model, bits[2], bits[4])
class ContentNode(template.Node):
def __init__(self, model, field, varname):
self.model = model
self.field = field
self.varname = varname
def render(self, context):
current_site = Site.objects.get_current()
try:
var = self.model.objects.get(site_id=current_site.id)
context[self.varname] = var.title #I get stuck here
because it not accepts input like var.field (I have extract the field
value above)
except:
context[self.varname] = "Value not found"
return ''
register = template.Library()
register.tag('get_site_att', do_site_att)
*The template query in base.html:*
{% load general_tags %}
{% get_site_att general.Naming title as title %}
{{title}}
{% get_site_att general.Naming tagline as tagline %}
{{tagline}}
I have tried all the possible ways I can think of, but just can't get
it works. Any help is really appreciated. Thanks.

I'm using Django Forms to do a filtered/faceted search via POST, and I would
like to Django's paginator class to organize the results. How do I preserve
the original request when passing the client between the various pages? In
other words, it seems that I lose the POST data as soon as I pass the GET
request for another page back to my views. I've seen some recommendations to
use AJAX to refresh only the results block of the page, but I'm wondering if
there is a Django-native mechanism for doing this.
thanks

Is it madness to process uploaded tars and zips completely in memory?
Hi, I am writing an app to "apply some rainbows and unicorns" to a bunch of uploaded XML files (which can be uploaded as a compressed tar or zip file). Celery and rabbitmq will be used for the asynchronous tasks with jQuery (maybe with dajaxproject) to get updates on progress to the browser. I'm at the point where I'm passing the uploaded files to my offline tasks and using cStringIO with both the tarfile and zipfile modules to handle the whole compressed files as strings and then saving the decompressed XML files in an array of strings to be later manhandled by cElementTree. There is a closed audience for this app and uncompressed filesizes will never be more than 3 or 4 MB (mostly they'll under 100KB). I don't expect this to be used by more than a handful of people per day (but it will save _alot_ of man hours). Is it madness to try to do this all in memory? Should I write out the file contents to the filesystem first using "for i in uploadedfile.chunks()"? Does anyone know of any open Django apps that do anything similar (upload a file, get presented with the results) so I can have a look?

Re: Is it madness to process uploaded tars and zips completely in memory?
All depends on whether; - you have enough memory - you are going to enforce the file size - you have appropriate resource limitations in place on the server - you are going to enforce the maximum number of processing requests etc etc... Personally, if all those conditions were met, I'd probably do it in memory to avoid the unnecessary disk IO overhead.. but it all depends on what you need :) On Tue, Nov 2, 2010 at 1:00 PM, wawa wawawa wrote: > Hi, > > I am writing an app to "apply some rainbows and unicorns" to a bunch > of uploaded XML files (which can be uploaded as a compressed tar or > zip file).

Judging from http://code.google.com/p/django-rest-interface/ you
aren't using the XMLResponder class at all correctly. As far as I can
tell, one is supposed to use XMLResponder to define a 'resource',
which is then provide as the callable in urls.py.
You are using it as a replacement for HttpResponse, which it isn't,
and because it isn't you get the error you describe.

rabbitmq + celery + django + celery.views.task_status ... simple example?
Hi All, So, I've got my django app, rabbitmq and celery working and processing my uploaded files.

I'm a little new to JSON / AJAX (AJAJ!) and I'm struggling a little with the templates and views part. Are there any easy examples out there? I can't seem to find any!

Physical / Logical Hrefs
Given the following in my main page template how does Django process
logout? I am asking this, because I want an href to take an
authenticated user to a page that, for example, allows the collection
of some data (billing reads).
I have an application within the project that will handle read snaps.
I am assuming /read_snap will cause Django to jump to the read_snap
application. Is that correct?

Re: Mod_Python and everything loaded, Apache serving HTML files without using Django first
This isn't directly related to your question, but mod_python is not a recommended method of deploying Django. Support for it will be deprecated. You might want to check out mod_wsgi.

Re: admin usage
I always had the opposite impression. The Admin can be modified quite extensively to handle most cases for regular, on-going, data entry for multiple models.

Re: Trying to determine the duplicate SQL queries from my view code
OK so I have solved this, the flaw being my understanding of the
cacheing of Django database QuerySets. I still have not eliminated
the double auth_user request because one is made in the
@login_required directive and the other is made in the view code to
pass user data to the template. However it is easy to see how in
Django:
# Set the course_id
course_id = enrollment.course.id
# Get the requested course
course = Course.objects.get(id__exact=course_id)
Will result in two separate queries to get the course with that id.
It can be solved easily with:
# Get requested course and set the course_id
course = enrollment.course.id
course_id = course.id
which reduces the number of SQL queries by 1 each page request or
shaves off about .4ms per page view.

Re: Repost Admin Site Without Graphics
So your admin media (js, css, images, etc) isn't working? Try two things: 1. Open the source of some admin page. Look at some image, css, or js object. Find the path where it is pointing. Does this path makes sense? (Have you put it in the settings.py file?) 2. Check your site settings. If you are using django's web server, it will serve the admin files automatically, if you are using apache or some other web server, you will have to specify where the admin site's files are, like Robbington said. Compare the path in the settings file to the one that is being served. ... On Tue, Nov 2, 2010 at 11:58 AM, octopusgrabbus wrote: > Tried suggestions, and still do not get full graphics.

Change the initial data to a modelForm
Hello list. I have a model "PP" with a "float" field "val" and a modelform for this model For update the data of a existent "PP" I use a form like this Form_for_PP(request,POST, instance=instance) Now my question is, Can I change the initial data for the field "val"? I want to do this: If the value in "val" is 12345.6, the resulting form must to have the value "12.345,6" (the same value, but formatted) I can't find the way to do this when I use an instance. Set an "initial" don't work, the returning value is always the existing in the DB. Somebody can help me?

I don't think you need to change the value, but rather add localization so add proper formatting. http://docs.djangoproject.com/en/dev/topics/i18n/localization/#format-localization -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: 2D map application: performance and design question
Ok, thanks for the suggestion, Javier. I implemented this and it showed: I'm spending about 0.2 secs for the queries, but 1.5 secs for t.render(c) ! So rendering the template seems to take a significant amount of time! As you can see, my template code iterates over about 13*13=169 objects that have been passed in the context. I then made tests to reduce this number. Here is the result of time spent for the query and render() as a function of the grid size: 3*3: 0.03s, 0.1s 5*5: 0.04s, 0.25s 7*7: 0.08s, 0.45s 9*9: 0.13s, 0.72s 11*11: 0.17s, 1.1s 13*13: 0.2s, 1.5s Lars On Nov 2, 4:46 pm, Javier Guerra Giraldez wrote: > On Tue, Nov 2, 2010 at 3:35 AM, Lars Ruoff wrote: > > Ok, so having excluded SQLite and the static served files, I'd like to > > test if the server matters.

Empty Response
I am returning a json structure in one of my views after the user performs a search when I only run Django's built in server. Following the asynchronous GET I get a response with the expected json structure which I can then use to populate the page. However, when I have Apache in front, the response is empty. And this appears to be only when I make an AJAX request since all of the other requests and responses produce the expected results. I don't know how to go about troubleshooting this. Does anybody know what is going on here? Or, how to troubleshoot this? Thanks! Eric -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: 2D map application: performance and design question
I would suggest rewriting the loop in your template as a templatetag.
Something like this
@register.simple_tag
def render_locations(locations):
html = u""" html %(x)s stuff %(y)s here %(link)s """
return '\n'.join([html % { 'x': loc.x, 'y': loc.y', 'link':
loc.link } for loc in locations])
I've used this approach a few times with good results for my use cases.

Knut

Validate single field in model
Hello,
I try to validate a single field in a model.
I know I can validate the field in a ModelForm like:
def clean_FIELDNAME(self):
if self == 'This is a test':
raise forms.ValidationError("ValidationError")
But can i do something similar in the Model itself ?

Struggling with aggregation/annotation
Hi,
currently I am moving my django project towards Django 1.2. During
that step I want to replace code like that
query_set = query_set.extra(select = {
'image_count': '''SELECT COUNT(*) FROM image
WHERE topic.id =
image.topic_id
AND topic.trashed_at =
image.trashed_at''',
'video_count': '''SELECT COUNT(*) FROM video
WHERE topic.id =
video.topic_id
AND topic.trashed_at =
video.trashed_at''',
})
Selecting a topic instance or a list of topic instances I also want to
know the amount of images associated with the topic, which share the
same value for trashed_at.
Can this be written using the annotate method and the Count class?
Best regards,
Oliver

Thanks for the reply, Django password_reset view used send_mail()
which seem to send only text. apparently you have to use
EmailMultiAlternatives as you pointed out to send html content guess I
will have to create my own view and use this instead if I want to send
html. Then again it is probably a good idea to send password reset
information in plant text. Since it pretty any email client would be
able to read plain text.
Thanks again

Re: Empty Response
You can easily look at the request/response by using firebug. TIP: Notice if there is a redirect. Sometimes depending on the config, for example, if django is set to append a / at the end, meaning it will do a redirect, then your request or response might be getting lost in the redirect (an HTTP 302) http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html When you have django running with apache config might be different. So first step is look in firebug what requests are being made.

Thanks, but I don't think it this particular query can be done just with django
annotations. If it can, I don't know how. But I think it would require either
an extra select or raw SQL.

Re: Import csv file in admin
Jirka & Everybody
Back to basics is always a good advice. With your help and this guy:
http://www.beardygeek.com/2010/03/adding-views-to-the-django-admin/
I can create a form to upload csv files and input their records into
the database.
Short history:
Forms.py:
class DataInput(forms.Form):
file = forms.FileField()
place = forms.ModelChoiceField(queryset=Place.objects.all())
def save(self):
records = csv.reader(self.cleaned_data["file"])
for line in records:
input_data = Data()
input_data.place = self.cleaned_data["place"]
input_data.time = datetime.strptime(line[1], "%m/%d/%y %H:
%M:%S")
input_data.data_1 = line[2]
input_data.data_2 = line[3]
input_data.data_3 = line[4]
This form was imported in a view:
@staff_member_required
def import(request):
if request.method == "POST":
form = DataInput(request.POST, request.FILES)
if form.is_valid():
form.save()
success = True
context = {"form": form, "success": success}
return render_to_response("imported.html", context,
context_instance=RequestContext(request))
else:
form = DataInput()
contexto = {"form": form}
return render_to_response("imported.html", context,
context_instance=RequestContext(request))
And add the url pattern & some little changes to the admin index
template, and everything works the way i want.
Thanks guys!

Re: admin usage
Probably so, we do have stuff that tends to be JavaScript intensive at times, in some places we have a few AJAX queries (for example selecting a warehouse and loading the relevant part numbers for the next field based on the client) that may not be necessary, to stuff like Maps with OpenLayers for routing or pinpointing locations. What kind of applications/situations do you find more suited for reusing the admin module?

Re: admin usage
My applications are in the science domain, where data entry is quite intensive. Aspects such as AJAX and dynamic lookups have been incorporated into the standard Admin. Obviously there is additional functionality that had to be added; e.g. adding data via uploads from spreadsheets, and point locations on maps. Data "extraction" - reporting and querying - has had to be written as well. These are included as "seamless" parts of an overall customised Admin interface: primarily because the people doing the data entry are the same ones who are extracting data from it. I appreciate that in business scenarios you may have a worker/manager split and need quite different interfaces for each group.
