Re: ModelForm save call with data and instance

I Found problem, it was triple collision:
pycharm debugging sideeffect, wrong inheritance in _init_, but most 
destructive was form fields: it overwrites instance values with None.

And this would be a probable query:
Items.objects.extra(where=['created_by_id in (select e.user_id from
myapp_employees e, myapp_organization o where e.org_id = o.id and o.id =
(select o2.id from myapp_organization o2, myapp_employees e2 where e2.org_id
= o2.id and e2.user_id=3)) ']).count()

Can some expert in django-ORM comment on this? (can the same be done without
a 'where' clause)

As  someone pointed out in IRC, i want to go up, down and then sideways in
this query ;)

This is the equivalent raw sql:
select count(1)
from myapp_items a
where a.created_by_id in
(
select e.user_id
from myapp_employees e, myapp_organization o
where e.org_id = o.id
and o.id = (select o2.id from myapp_organization o2, myapp_employees e2
where e2.org_id = o2.id and e2.user_id=<>)
)

Design-wise, i do not think dynamic db creation is a good idea. Its tough to
maintain and prone to errors.
If you are using Oracle DB, probably you can think in terms of setting VPDs
for loading/restricting access.

Did you try creating a page and showing the information there - for eg. you
could create a link called 'Reports' on the top right of the page
and (after you extend the admin-base html file),  include the necessary
logic in the views.

Well, yes and no.

If you're using database backed storage, then no. The only way to
determine if there are messages or not is to query the database and
determine if there are messages. There's no magic mechanism here.

However, there are other message backends that don't require database
access. Django ships with a cookie-backed messages engine. Since the
message storage is a pluggable interface, it's also possible to build
a messages backend that stores in memcache, redis, or some other
non-database store. These don't require database access because they
don't store messages in the database. Whether they will work for your
situation is entirely up to your requirements.

Yours,
Russ Magee %-)

Re: django/python performance vs play/java

[drakkan]

Hi,

thanks for your comments, I installed django-debug toolbar and I can
confirm I'm doing similar queries from both django and play. The query
I do with hibernate in play should be slower since I'm doing a left
outer join while django do an inner join, since the field on which I
join cannot be null.

I tryed gunicorn but it gives similar performance to uwsgi, I'm
testing on my latptop (1 core). Maybe there is something wrong in my
template but it is basically a base.html and then index.html that
extends base.html, additinally I have some "include "
where other.html is a small fragment of code

We all know python is slower in raw execution speed than it's brother Java but 
I can't imagine it to be _that_ slow.


Maybe there's something wrong with the queries you perform. Django's ORM is 
know for it's 'hidden execution' of queries. Some more insight in your querying 
code might be useful.

Re: Setting up EC2 for Django

[Nate Aune]

If you don't need SSH access to the machines that power this whole setup, 
you can use DjangoZoom, our one-click Django deployment and hosting service. 
It's built on top of Amazon and uses Nginx, PostgreSQL and as of a few days 
ago, we also now support Mercurial. The only gotcha might be Solr which we 
don't support yet, but you could probably connect a 3rd party Solr provider 
such as http://websolr.com to satisfy that requirement.

Sign up for the beta at http://djangozoom.com and mention that you heard 
about it on this thread to get an invite.

I need to do reports, and I would like reports that are integrated with django admin.

[Kase]

I have no problem to make my pages with reports of objects, but I like
that are integrated with django admin, in the same tuple in the object
list.

i dont know if exist extention, but one of these reports is complex
= /

I have an object, insurance, customer, policy, policy_year

and a i need a report containing the information of the client
relationship, policies (foreign key (customer)) policy_year (foreign
key (policy))

and display somthing like this

Customer: jon doo
Policy: x
2009
2010
2011
POLICY AND
2008
2009

I would like to make it accessible from the list of objects "customer"

PS: i know how to display this info in to view + template but really i
like to display in django admin ...

Re: Dreamhost Virtualenv Question

[Jeremy]

AHHH, that makes a little more sense.  I'm trying to install apps from
Github.  Things like Pinax, and different individual blogging apps so
that I can "plug" them into one Django project to give it multiple
bits of social functionality.  Obviously I'm having a lot of trouble
(some of it being that it sounds like I don't even know what I'm
saying).  I've tried to install these apps through PIP and other forms
on Dreamhost, but it keeps saying that I don't have permission.  The
way that I believed to get around this is to set up virtualenv on my
shared server space, and create the project inside of that, correct?
But if I do this, how can I view the project that I creating live?

Again, if this all sounds foolish, keep in mind I'm incredibly new to
all these concepts and my not understand them enough.  I've been
looking for someone locally to give me some Django lessons, but I keep
coming up dry.

Let me know if anyone can assist me.  Thanks guys.

Re: ANN: django-iadmin

[Tomáš Ehrlich]

I'm using latest Django svn checkout.

I've just solved this problem, although still don't understand it.

Problem was with models simply registered to admin like:

admin.site.register(TaggedItem)

So, I created simple model admin and it works:

class TaggedItemAdmin(admin.ModelAdmin):
pass

admin.site.register(TaggedItem, TaggedItemAdmin)

Re: django/python performance vs play/java

[Maksymus007]

Of course Java IS faster by a few factors then Python. I switched recently
to Play development from django and I also noticed different. Moreover Play
uses many mature tools, like JPA/Hibernate, ehcache etc which are called
industrial standards.
One more thing - Play! uses its own build-in http server, and keep one
connection to a database alive at all the time, Django run as FCGI or
mod_wsgi manages this a bit different.

Re: ANN: django-iadmin

[Tomáš Ehrlich]

Hi Sax,
thanks for your work, i've already put it into my project.

Unfortunately, I've got this error when accessing change_list view.
Some apps works fine, but some of them shows this exception:
File "/usr/lib/python2.6/dist-packages/django/contrib/admin/views/
main.py" in __init__
  81. self.query_set = self.get_query_set(request)

Exception Type: TypeError at /admin/markup/textprocessor/
Exception Value: get_query_set() takes exactly 1 argument (2 given)

I'm trying to figure out, what's wrong. Just posting in case you know
about this.

Does github have any issue tracker?

Thanks

According to most benchmarks, Python (that is: current canonical
implementation of...) is indeed way "slower" than Java (idem), that's
a fact. FWIW, according to the same benchmarks, Java is slower than C+
+, which is slower than C, which can be slower than your-platform-
highly-optimized-assembly-code - but you need to be very good at hand-
optimizing assembly code to beat any decent C compiler.  You may
notice a pattern here (if you don't, try implementing a simple blog in
assembly, then port it to a different platform, and come back when
you're done ).

To make a long story short: if you're looking for raw execution speed,
forget about Java and go for C - and let us know when you'll have a
working prototype.

I can only second Shawn here. FWIW, virtualenv is just a way to have
different (more or less) isolated *Python* environments on a same

Please define "third party app" and "virtualenv project."

You can install a Python package in virtualenv using pip. "Viewing a
virtualenv project as a webpage" is nonsense.

I could guess at what you mean, but if you can clarify a bit it would help.

django/python performance vs play/java

[drakkan]

Hi,

I did a small test app that basically render a web page and do 3
queries to the database (these queries are needed to fetch some data
displayed on the web page). I deployed this app with nginx+uswgi

here is the relevant nginx conf:

location / {
uwsgi_pass 127.0.0.1:49152;
include uwsgi_params;
}

I configured nginx to serve the static files too:

location /media {
root ;
autoindex on;
}

I launch uswgi as follow:

uwsgi --chdir= --
module='django.core.handlers.wsgi:WSGIHandler()' --env
DJANGO_SETTINGS_MODULE=myapp.settings --master --pidfile=/tmp/project-
master.pid --socket=127.0.0.1:49152 --max-requests=5000 --process=5

then I benchmarked the app with ab:

ab -n 1000 -c 4 http://127.0.0.1:80/

so play is outperforming django! obviously django is not in debug mode
ecc..., is there something wrong in my test setup (I already tried to
adjust the uwsgi launch line I tryed more process or 1 process with
threads ecc with no relevant improvement) or django/python is simply
much slower than java? I tried to run play behind nginx proxy too: the
results are pratically identical. Note the response time too: the
slowest play response is 47 ms, the fastest django one is 110 ms,

any suggestion to improve performance is appreciated,

thanks in advance,

Complex Query help - get items from the org to which the user belongs

[Venkatraman S]

I tried asking around in IRC, and stumbled on a few possible solutions,
would be great if someone shed some more light:

I have the following models:

class Organization(models.Model):
  name= models.CharField(max_length=100, blank=False)

class Employees(models.Model):
  org = models.ForeignKey(Organization,
related_name='employees')
  user= models.ForeignKey(User)
  name= models.CharField(max_length=100, blank=False)

class Item(models.Model):
  name= models.CharField(max_length=100, blank=False)
  created_by  =
models.ForeignKey(User,related_name='created_by_whom')

Problem : I need to get all Items from the Organization to which current
User belongs to.
So basically, get all employees from the Org that the current User belongs
to, and then get all items created by these employees. (So, this query
should also include the current User).

Say there are 3 Users in an org : A, B and C with each creating 3,4,5 items
respectively, and 'A' is the current user; then i need a query which returns
all these items(i.e, 12 items) when i supply A..

Avoid DB hit while using messages

[Venkatraman S]

I am showing messages using the messaging framework; so i check if there are
any messages in my base.html (i.e, {% if messages %} ) and if yes i show the
messages with suitable styling.
Messages are being rendered fine and i do not have any problem with that.

But i see that , accessing 'messages' is causing a db hit - i.e, the 'if
clause above - is it possible to avoid this db hit?

Django trunk also contains validate_ipv6_address and validate_ipv46_address.

But as of 1.3 I think it only validates ipv4

Implementation of sso with django auth.

[Ricardob]

I'm trying to implement single sign-on using only django auth.

Let's assume two django projects, on different sub-domains:
site.com(auth) and app1.site.com(app1) The auth table in site.com is
master. site.com handles: login, logout, account registration, etc.

site.com sets SESSION_COOKIE_DOMAIN to .site.com to allow it to be
read by subdomains

app1 will have login_url set to a view in the app1 project, which does
the following:

retrieves site.com's session_id value(from cookie)
validates session_id by making a request to: site.com/validate/
[session_id]/
If False, redirects to site.com/login?next=[...]
If True, request user data to: site.com/attributes/[session_id]/
site.com/attributes/ delivers a dictionary with all the User
values, encrypted using a shared SSO_KEY(encryption done the same way
django encodes and decodes session_id)

Now, app1 has a model SSO_User which has two fields, a foreign key to
User model and an integer field. The SSO_User models links local auth
User to the id of master auth table.

Using the id retrieved from site.com, we check SSO_User for existing
local user, if true we simply update the values and login; if non
existing, we create the user and SSO_User and login.

app1(or any other sub-domain) can keep their own profile information,
without interfering with anything.

It seems simple to implement and safe, but before implementing I
wanted some opinions. What do you think?

No, it doesn't have any model level validation. If you check the
source, it is simply a char field with max length of 15 characters.
It's form field does have validation though, and you can add the same
validator used there as a validator on the model field:

from django.core.validators import validate_ipv4_address
...
ip = models.IPAddressField(..., validators=[validate_ipv4_address])

Also, as you can see in the name, this only supports IPv4. For a more
complete solution (requires postgres) I use the excellent
django-postgresql-netfields -
https://github.com/adamcik/django-postgresql-netfields

Model IPAddressField not validating?

[candlerb]

I have a model defined as follows with an IPAddressField:


class Nas(models.Model):
name = models.CharField(max_length=128)
ip = models.IPAddressField('IP Address', max_length=15,
unique=True)
nas_type = models.CharField('NAS Type', max_length=32, blank=True)
huntgroup = models.ForeignKey(Huntgroup)

class Meta:
verbose_name = "NAS"
verbose_name_plural = "NASes"

def __unicode__(self):
return self.name + " (" + self.ip + ")"


However, the model doesn't seem to validate that the ip field is a
valid IP address. Example:

>>> n = Nas(ip='wibble', name='bibble', huntgroup_id=12)
>>> n.full_clean()
>>> n.ip
'wibble'
>>>

However, it does validate other things, e.g. the presence of required
fields.

>>> n = Nas(ip='wibble', huntgroup_id=12)
>>> n.full_clean()
Traceback (most recent call last):
  File "", line 1, in 
  File "/usr/local/lib/python2.6/dist-packages/Django-1.3-py2.6.egg/
django/db/models/base.py", line 828, in full_clean
raise ValidationError(errors)
ValidationError: {'name': [u'This field cannot be blank.']}

is this a bug, or am I using it wrongly? I want to create models in
code, not in a form, but validate them before saving.

Thanks,

Brian.

db.StringProperty is not Django - are you sure you're at the right

But anyway, assuming you're using Django's templating system

{{ article.title }} and some more text
{{ article.title }} {{ some_var }}
{{ article.title }} {{ some_var.some_attribute }}

for the second and third examples you obviously need to have
"some_var" in the template's context, whether from the view or from a
context_processor.

FWIW, all this is fairly well documented in the FineManual(tm):
https://docs.djangoproject.com/en/1.3/topics/templates/

He read the docs, but he still had no idea of how to progress. So I
gave him a step by step precis of what he needed to change (which you
helpfully chopped out, making out like I replied just telling him to
RTFM), and told him to re-read the docs again.

Have you read the documentation I linked to? It actually does answer
that question perfectly.

Multiple Databases

[Nick]

Hi, I'm evaluating django for a project, though i haven't used it
previously. I have used pylons,sqlalchemy,elixir,formalchemy etc in
the past so am at least familiar, if a little rusty with that but i
would like to try django for all the it provides. I've read through
the docs and googled for a bit without any luck, so i'm here to ask
you for help.

I would like to have two main databases, i see this is covered in the
docs and is nicely implemented for general use cases. However, i also
need to support dynamic database creation - i.e. one or more databases
created from a single model (think of these as customer specific
databases). I will be using sqlite and want to save the path/
connection details of the dynamically created databases in one of the
primary db's. Is this possible and if so what is the best approach to
take?

Thanks
Nick

Re: Related model getting autocomplete="off"

[candlerb]

Sorry, please ignore this question.

All rows get autocomplete="off", and it doesn't make adifference.

The problem than autocomplete() doesn't work like live(): if you call
autocomplete() and then later add a new field to the DOM, that new
field doesn't get autocomplete enabled.

Re: change values in "select list"

[Andre Terra]

If he's going to ask around for help and show code, then English is
the language of choice, for the simple reason that more developers
speak it. As his questions grow in complexity (which is to be
expected) so will the burden of having to figure out the German words.

As for the python keywords, show me a non-obscure japanese programming
language and I'll concede. There's a reason no such thing exists.

For the record, English isn't my first language either. I'm pretty
sure a lot of German companies code in English much like Brazilian
companies do.

There are numerous references online that talk about this issue, so
for the sake of everyone in the list I'll refrain from extending the
matter any further.

Andre Terra

I couldn't disagree more strongly.  The fact that Python's keywords
are in English has NOTHING to do with the choice of variable names;
you might as well argue that because APL is in love with Greek
letters, all APL programs should be written in Greek.

The argument about a non-German-speaking developer is just plain
silly; the application is being developed by a German-speaking company
in a German-speaking country.  If they hire a non-German-speaking
developer, that person will necessarily learn German very fast.

(Reductio ad absurdum: since every major programming language uses
English keywords, you are fundamentally claiming that it is a mistake

Related model getting autocomplete="off"

[candlerb]

I have an Admin view on a model which has related (child) models. I
have extra=1. It displays like this:

[Child1]
[Child2]
[ ]
+ Add another Foo

I have jQuery autocomplete attached to those model fields.

All is fine, except: when I click on 'Add another Foo', the
dynamically added field has autocomplete="off", and so autocomplete
doesn't work there.

The only place I can see autocomplete set is in media/js/inlines.js,
but that's for fetching a couple of global fields.

Any idea if this behaviour is intentional, or a bug? (Django-1.3)

Thanks,

Brian.

If you're copy/pasting test that's not Markdown, then Markdown will
not magically help you. If you have unformatted text that you want to
turn into html, you're probably going to have to do a little text
pre-processing. Good news: you're using Python and text processing is
easily in python.

An easy way to practice learning how to admin linux servers is to
download virtualbox and then download a server image (*.iso) from your
linux distro of choice (I prefer the Ubuntu/Debian side of things..
rec Ubuntu server). You can set up and then destroy without doing any
damage so you can easily setup again. The only way to learn this stuff
is to just get your hands dirty... it's not hard just kind of hard to
google generally. It's better to have specific errors to google for.

you might be better with

Re: Confusing path example for mod_wsgi?

This has to do with 1/ how Python looks for modules (sys.patth), 2/
the fact that your manage.py from the root of your project (and not
from the parent directory) and 3/ some weird things happening with
manage.py and not when running behing apache or another web server.

wrt/ point #1 and #2: Python looks for modules / packages in the path
listed in sys.path, which always start with the current working
directory, so when you're running manage.py from within directory
"foo", foo is first on your sys.path, and you can directly import
'bar'. When running mod_wsgi, if you only adds "/path/to" in your
sys.path, Python will be able to find package "foo" (yes, your Django
project IS a Python package - it has a __init__.py file), and from
this sub-modules (foo.settings) and sub-packages (foo.bar), but NOT
'bar' (there's no package named 'bar' in your sys.path at this
point).

You can either add both '/path/to' and '/path/to/foo' in your sys.path
and point os.environ['DJANGO_SETTINGS_MODULE'] to 'foo.settings' and
settings.ROOT_URLCONF to 'foo.urls',  or only add '/path/to/foo' in
your sys.path and point os.environ['DJANGO_SETTINGS_MODULE'] to
'settings' and settings.ROOT_URLCONF to 'urls' (but then any use of
'foo.whatever' will break).

As far as I'm concern I prefer the second solution - I don't want to
have to change anything in my code when I rename my project dir or
move an app to another project or whatever.

wrt/ point #3, I can only point you to Graham Dumpleton's excellent
post:

Users must be authenticated before you call login. You can
authenticate them using a custom auth backend:

https://docs.djangoproject.com/en/1.3/topics/auth/#handling-authorization-in-custom-backends

Define your own custom auth backend (in addition to the current one
you are using) which takes an optional 'openid_authenticated'
argument. The authenticate method in the auth backend should simply
find the user with the appropriate username, and return it.

When you receive a user authenticated through openid, simply call
django.contrib.auth.authenticate, passing this new additional
argument. The user returned from djanog.contrib.auth.authenticate will
then have the appropriate backend set, and login will correctly store
the right parameters in the users session.

Cheers

Tom

You're calling a function called 'login' from inside a function called
'login'. It's not going to end well. Either call your login view
function something else, or import django.contrib.auth.login using a
different name (from django.contrib.auth import login as
django_login).

Cheers
