Raw-sql and the snippet provided by me would end up generating the same sql.

One advantage of my snippet is, if your db does not support sin/cos
functions(like sqlite3),
then you can go ahead defining funcs which computes the same. Something
like..
from django.db import connection, transaction
cursor = connection.cursor()
import math
connection.connection.create_function('acos', 1,
math.acos)
connection.connection.create_function('cos', 1,
math.cos)
connection.connection.create_function('sin', 1,
math.sin)

Thanks all for the help,
I really appreciate it.

I think I would go ahead with executing the raw SQL in this case.
The solution by @Venatraman looks interesting too. I would give it a
try.
I might write a stored procedure if I start getting performance issues
if data starts growing.

Thanks again,
sanket

Re: ANN: django-iadmin

2011-07-10 Thread David Graves

Björn,

I'm working on a project very similar to this one (but have a long way to go
to reach it's maturity), but I do have a working feature that I believe
matches what you're looking for.  The project is at
https://bitbucket.org/graveyboat/gravey and the feature is called
RestrictedModel.  It acts just like a regular model, but the object is
automatically assigned to the user that created it, and the user is allowed
to grant access to any group he/she is in.  Also, any admin can change the
owner of the object.  It can be used by using
gravey.db.models.RestrictedModel and gravey.admin.RestrictedModelAdmin.  As
I mentioned before, the rest of the project has a long way to go, and I need
to get some documentation up, but hopefully this will help you along the
way.

Hmm, yes, that'll do. I was hoping for getting away without the iteration.

Btw, i guess you are using uni-form - its perfect for large forms, as 
you have to only specify the layout as a layout and the rendering is 
taken care of by it.


Nope, I use div-based form with some hacks to create sections. I didn't

Not exactly, using ORM is pretty easy too. You would do something like this:

results.extra(select={
'distance':
'(acos(sin(latitude)*sin(%(latitude)f)+cos(latitude)*cos(%(latitude)f)*cos(%(longitude)f-longitude)))'
% {
 'latitude': latitude,
 'longitude': longitude

Re: Scaling to 30k requests (malcolm box blog)

Thanks for sharing; in my app(which is no way to be compared with any BIG
site) i was trying to do some optimizations to make it 'fast' - just to
learn more.
I used google page-load , YSlow, and DDT to cleanup most of the expensive
sql queries and other things related to HTML.
I am not using any kind of caching for now, but when i ran ab on my app, i
see that django template rendering is pretty expensive.

Jinja2 seems to be nice and fast; but i have got a tonne of templates and do
not have the time to move them over. There is a GSoC project which, i hope,
would do some justice to this layer to make it fast.

On the DB front, i found that select_related() was a welcome boon ; which i
somehow missed. For eg, when we send a list of departments to a template and
iterate over it in the template, and the department tries to access some
other model, then 'every' access is a db call. So if you are showing 100
departments in one page - then you make 1 call to get all departments and
100calls to get each to access the object in the  'other' models(pretty
painful!)

To learn more about  DB access optimization in Django :
https://docs.djangoproject.com/en/dev/topics/db/optimization/

Having said that, it shows clearly that if you design your app nice and
pretty, you can change anything in your server stack to make it even more
scalable and robust. I would highly recommend, concentrating on architecting
the app first and then thinking about the deployment options.

Emailing submitted forms

2011-07-10 Thread Michael Ludvig


Hi,

I've got a pretty lengthy form in Django 1.2.5 - it renders well with {{ 
form.as_p }}.


Now I need to not only save the entered values to the db (that works 
well) but I also need to send a copy of the submitted form to an email 
address.


I wonder if there is an easy way for rendering the form into a static 
html email. Essentially I want to replace all the  and  
widgets with their value and then print it as {{ form.as_submitted }} 
kind of.


As the form is quite long I don't want to maintain a field-after-field 
html template for the results.


Is there any convenient way to do this?

Thanks!

CSRF problem with /i18n/setlang/

2011-07-10 Thread cjwalter

Hi all

I continue getting

CSRF token missing or incorrect.

when trying to call /i18n/setlang/

Here the pertinent snippets from settings.py:

MIDDLEWARE_CLASSES = (
'django.middleware.common.CommonMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.locale.LocaleMiddleware',
)

and from templates/base.html:

{% load i18n %}
{% get_current_language as LANGUAGE_CODE %}
{% get_available_languages as LANGUAGES %}


{% csrf_token %}


{% get_language_info_list for LANGUAGES as languages %}
{% for language in languages %}
{{ language.name_local }}
({{ language.code }})
{% endfor %}




What else is needed??

TIA

Hmm, grp is only valid on unix platforms according to here:

http://docs.python.org/library/grp.html

https://github.com/saxix/django-iadmin/blob/master/iadmin/plugins/fm/fs.py

*line 4-6:*

from grp import getgrgid

from pwd import getpwuid

*Replace with this:*
*
*
import os
if not os.name == 'nt':
from grp import getgrgid
from pwd import getpwuid


*line 40-41:*

self.user = getpwuid(itemstat.st_uid)[0]
self.group = getgrgid(itemstat.st_gid)[0]

*Replace with this:*

if not os.name == 'nt':
self.user = getpwuid(itemstat.st_uid)[0]
self.group = getgrgid(itemstat.st_gid)[0]
else:
self.user = 0
self.group = 0

This may or may not work lol.

hi, sax
After downloading the newest code and i try to implement the iadmin
the setup works well this time but when I try to access the localhost/admin
got the follow error ,

My platform Win2008R2, python 2.6.6

I checked the code found something,
I write my code in Win, and in Win python can not import grp.
but when i try import in FreeBSD it works.My win's python install
by default.
So I think your iadmin is not suitable for Windows now.

You could execute the raw sql query string, see: 
https://docs.djangoproject.com/en/dev/topics/db/sql/
for more information on the subject. Seeing the complexity of the query and 
knowing it's a good working version why should you even bother translating it 
to django's ORM framework ?

need help with calling following complex query

2011-07-10 Thread sanket

Hey All,

I am quite new to Django and recently started using django for
developing a location based service.
In order to find the places in near by area I want to make following
mysql query. but I am not sure how should I translate it using django
models and managers.

orig.lat = x
orig.lon = y

"SELECT  destination.*,
3956 * 2 * ASIN(SQRT(  POWER(SIN((orig.lat - dest.lat) * pi()/180 /
2), 2) +
COS(orig.lat * pi()/180) *  COS(dest.lat * pi()/180) *
POWER(SIN((orig.lon -dest.lon) * pi()/180 / 2), 2)  )) as
distance
FROM place as dest
WHERE  dest.longitude
BETWEEN lon1 and lon2
AND dest.latitude
BETWEEN lat1 and lat2
"

the model which talks to database is called Place in my case.

Thank you all for the help,
sanket

Need help intercepting SQL

2011-07-10 Thread Eric B

Our web site uses Django 1.2.  We're adding a layer to our MySQL
database called dbShards for fragmentation (sharding).  I need to
prepend instructive SQL comments (/* ... */) to UPDATE statements in
certain situations.  What's the best way to intercept the raw SQL sent
to the database?

I've come up with a couple ideas, but feel they are too invasive and
that there must be a better way.

Here's an example:  If the following code ...

em = ExampleModel.objects.get( id = 1 )
em.fieldname = "example"
em.save()

Generated the following SQL:

UPDATE examplemodel SET fieldname = 'example' WHERE id = 1;

Then I'd want my intercept code to prepend a comment like this to the
update statement.

/* example comment */ UPDATE examplemodel SET fieldname = 'example'
WHERE id = 1;

Thanks,
Eric

Oh jeez, looks like that release is broken.

Go to here: "D:\saxix-django-iadmin-ec7ad2a\setup.py", line 44

And replace this line:
version = ".".join(iadmin.__version__),

With this:
version = ".".join(map(lambda x: str(x), iadmin.__version__)),

(the above just basically recasts the values in that list as string objects,
rather than ints. I suspect this was caused by the string not having a dot
or something)

Let me know if that works.

Scaling to 30k requests (malcolm box blog)

2011-07-10 Thread Cal Leeming [Simplicity Media Ltd]

Came across the following blog entries today, for those interested in this
sort of thing:

http://attentionshard.wordpress.com/2011/04/26/scaling-django-to-3-requests-per-second/

http://attentionshard.wordpress.com/2011/04/03/scaling-to-30k-two-level-caches/
Interesting approach. Although you'd have to be careful what context it was
used in (i.e. if your code is written under the assumption that the caching
server is atomic).

http://attentionshard.wordpress.com/2011/04/26/scaling-to-30k-tsung/
Never heard of tsung before, looks pretty nice. Will try it out for sure.

http://attentionshard.wordpress.com/2011/05/03/scaling-to-30k-haproxy-on-ec2/
Can't comment much on this, as we've never used haproxy.

The stack they have used is quite interesting. Although they are using
Apache w/ mod_wsgi (which tends to be a lot slower than using nginx with
uwsgi), they still seem to have got some decent performance out of it.

http://attentionshard.wordpress.com/2011/06/21/behind-the-scenes-using-cassandra-acunu-to-power-britains-got-talent/
Explains a bit of their usage of using Cassandra. Would be interesting to
see some benchmarks though.

Toggle boolean fields from a Queryset using F objects

2011-07-10 Thread vascop

I've tried these queries with these results:

queryset.update(done=not F('boolean'))
{'time': '0.001', 'sql': u'UPDATE "todo_item" SET "done" = True'}

queryset.update(done=(F('boolean')==False))
{'time': '0.001', 'sql': u'UPDATE "todo_item" SET "done" = False'}


What I would like is something like this:

queryset.update(done=F('done'))
{'time': '0.002', 'sql': u'UPDATE "todo_item" SET "done" =
"todo_item"."done"'}


But with

SET "done" = !"todo_item"."done"
to toggle the boolean value

I assume _start / _end / _size are references to the address space (within
the binary) where these embedded binaries (in symbol form) are kept??

Is there any sort of restrictions on maximum allowed symbol size? (looked on

Just had a look at http://projects.unbit.it/hg/uwsgi/rev/2cc21926d986, to

That looks pretty straight forward. The C code looks fairly simple to work
with too, so I might even be able to make some changes along the way.

I'll give this a real good thrashing tomorrow, and will let you know the
results.

Once I've played with this tomorrow, I'll type up a full report on what I

it. I'll also forward this to the mailing list to keep everyone updated.

Re: merge images into a webpage

You can easily do this in your template with an index. Assuming you'll 
have the variable image_list in your context which is a list, you can do 
this:


{{ image_list.0 }} and {{ image_list.1 }}

Re: my frist django project Error

2011-07-10 Thread Malcolm Box

Cal,

You are contributing a lot to the django users group, but this response isnt in 
the best spirit of the group. 

Yes, the op could work out from the traceback what the error was, but we were 
all beginners once. If you compare this post to the how to post FAQ its not too 
bad - at least there's a traceback. 

Telling someone they need to learn more python isn't helpful - tell them that 
theres a setting missing and how the traceback makes that clear. 

Sorry to pull you up on this but the helpfulness of this list is important both 
to me and the health of the django community. 

Malcolm

You should never really put HTML inside a method unless you *really* have to
(even if it's for performance, unless your site is getting thousands and
thousands of hits a minute, then just use a template)

I'm a bit confused as to how you are getting the image list in the first

Re: merge images into a webpage

Ok perhaps a basic question. I wrote a custom method for my model:
def image_list(self):
return '' %
(self.image, self.alt)
And i indeed get a nice list of image in the template. I want however
control where the single images show up. With something like {{image.
1}} other text {{image.2}} in the text.

How do i accomplist this?

It's easy to forget that Django is just Python. You're the programmer, 
so if you want to add a method then go ahead. It's best to understand 
Django's design as well as possible before you go adding things because 
sometimes things are done for a good reason.


But in the end, you're the developer responsible for delivering a 
working product, so do what you have to do.

Re: 'WSGIRequest' object has no attribute 'update'

May we see the rest of your view? If not, you'll have to figure it out 
by examining exactly what your 'request' variable contains. The error is 
clearly from calling update() on it, and it not being allowed.

Re: Manytoone Form

I don't know what your models and form look like so I can't say exactly. 
However, you probably need to just modify one of your clean functions so 
it retains multiple values, and update your save function to do the 
right thing when it gets more than one.

How about this..

---
Asking question about Python related subjects is fine as long as;

* You follow the same guidelines as the rest of this document
* The question itself is somehow vaguely related to your Django project
* You understand that learning Django will involve learning Python as well.

For those who would like to read some tutorials on the basics of Python, you
could try:

That sounds fair.

I think this clause would be mostly aimed at newcomers who are expecting
they can use Django, without having to learn Python (for example, asking
questions about Python which are easily answered on Google).

Yeah this is a tricky one. Perhaps the same 'intuition/laziness' rules

Form wizard get_template_names()

2011-07-10 Thread Dario Vergara

Hi,

I am using the development version of FormWizard. The documentation
says that you can change the default template name by overriding
get_template_names(). My implementation seems to always return the
same template:

class MyWizard(SessionWizardView):

def done(self, form_list, **kwargs):
return render_to_response('done.html', {
'form_data': [form.cleaned_data for form in form_list],
})

def get_template_names(self):
return ['./mysite/step_1.html','./mysite/step_2.html']


Any idea on how to make the template change to step_2 after the user
clicks next on step 1?

The documentation on how to implement this method is missing from
https://docs.djangoproject.com/en/dev/ref/contrib/formtools/form-wizard/.

Not that your write up suggests this, but I am cautious to turn folks away
from django-users because they ask a python only question.  From a venn
diagram perspective the django community is a subset of the python
community.  Using Django to teach folks more about Python is a win for
everyone (django, python, open source, ...).  My personal heuristic on what
is off topic on django-users for python specific questions is this:  if the
question is python only, if it is ultimately going to be used in a django
project, then I consider that on topic.

(UsingTheMailingList) Pre-requisites for newcomers on Django

2011-07-10 Thread Cal Leeming [Simplicity Media Ltd]

We don't seem to have a policy of dealing with mailing list posts in which
the user clearly has no Python experience.

Therefore, I'd like to hear some thoughts on making an amendment to
UsingTheMailingList,
which states:

"""
Do you have *any* experience at all using Python, or understand the basic
concepts of how Python work?

If not, please refer to the following before attempting to use Django:
http://wiki.python.org/moin/BeginnersGuide/Programmers

"""

This would be just the same principle if someone wanted to learn, say
"CodeIgniter", but without having to learn PHP. It's just not gonna fly,
right?

Re: http auth using django auth_user table

2011-07-10 Thread Cal Leeming [Simplicity Media Ltd]

The only connection this question has with Django, is the encryption method
that Django uses, and therefore is inappropriate for this forum.

Please refer to http://code.djangoproject.com/wiki/UsingTheMailingList

On a site note, it took me less than 10 seconds on Google (with a very
simple search term - first result) to find the answer you needed, which
shows either lack of intuition or total laziness on your part.

Re: Manytoone Form

2011-07-10 Thread Magrelo

Thanks Shawn, I've done this, the only problem now is if I select only
one field the override save method works fine, but if I select more
than one, the field comes empty on the save method.

Any tips?

Thanks again!

http auth using django auth_user table

2011-07-10 Thread Ali Rıza KELEŞ

Hi,

I want to use django auth_user table for authentication of another
application which uses "apache basic auth" with module auth_mysql. The
code below runs well with MD5 passwords without salt. But django works
sha1 and with salt.

What should I do?

Thanks..

AuthName "Hi.. Please login"
AuthType Basic
AuthBasicAuthoritative Off
Auth_MySQL On
Auth_MySQL_Authoritative on
Auth_MySQL_Host localhost

Auth_MySQL_User django-mysql-user
Auth_MySQL_Password some-password
Auth_MySQL_DB django-mysql-database
Auth_MySQL_Password_Table auth_user

Auth_MySQL_Empty_Passwords Off
Auth_MySQL_Encrypted_Passwords on


Auth_MySQL_Username_Field email
Auth_MySQL_Password_Field password
Auth_MySQL_Encryption_Types PHP_MD5

AuthUserFile /dev/null

Require valid-user

That's also how I would do it, some example code to make it even more clear:

from django.db import models
from django.contrib.auth.models import User

class UserProfile(models.Model):
user = models.ForeignKey(User, unique=True)
url = models.URLField("Website", blank=True)
company = models.CharField(max_length=50, blank=True)
