Re: caching of Models (not the cache middleware)

[Brian Craft]

Thank you!

'set transaction isolation level read committed' had no effect, but
'set autocommit=1' appears to fix it.

I wondered if there was some more general way of doing this (I mean,
besides passing in raw sql). Perhaps the set_autocommit() method in
db.backends.creation?

caching of Models (not the cache middleware)

[Brian Craft]

Digging into the problem I'm having with a standalone django script,
the problem seems to be that django doesn't see updates to the
database unless it writes to the database.

In the following lines,
   ss = engine.SessionStore(session_id)
   session=ss.load()

If session_id "abcd" has been added to the session table after the
script started, the load will not find it. Instead, it will create a
new session, say "wxyz" and write it to the table. After writing it to
the table, a subsequent load on "abcd" will succeed: it's now in sync
with the database, at least until another process writes to it.

Anyone know where this caching is happening? I have no caching
middleware enabled. Does django cache results of Model queries? Or
would the db layer be caching it? And how can I get django to sync
before looking up a session?

Are there any Django events we're missing on Lanyrd?

[Simon Willison]

Hi everyone,

My main project at the moment is Lanyrd, the social conference
directory. It's a site that helps you find conferences to attend or
speak at, and that enables you to build a profile of talks you've
given and events you've attended in the past.

There's just one problem: right now we only know of 5 upcoming Django
events, worldwide:

http://lanyrd.com/topics/django/

Compare to other technical topics, that's not very impressive:

http://lanyrd.com/topics/php/
http://lanyrd.com/topics/drupal/
http://lanyrd.com/topics/ruby/

Are there any events that we're missing? You can add them yourselves
(don't forget to attach the Django topic) or alternatively tip me off
via email and I'll add them myself.

We're also very interested in past events. We have 37 for Django at
the moment - again, if there are any missing I'd love to have them on
the site:

http://lanyrd.com/topics/django/past/

Finally, as a public service announcement we do have Atom feeds of
most of our pages, so if you want to hear about Django events as they
are announced you can subscribe directly to the above page.

We also collect videos / slides / etc - we have 47 session videos in
our Django collection which are worth browsing through, and we're keen
on gathering more:

http://lanyrd.com/topics/django/video/

We even have video from the first event after Django was released to
the public, way back in 2005! http://lanyrd.com/2005/snakes-and-rubies/

Cheers,

Simon

Re: DB-Views or read-only tables in models

[bvdb]

Thanks for describing the four possible reactions.
My main concern is organisation, alas I imagine a Django solution, not
just one for me.
So the model needs to know about the view, i.e. we'd need a read-only
attribute in models.py table definitions, so that
a) Developer sets the attribute manually in models.py
 or
b) manage.py inspect recognizes the views and sets the attribute

Then I can use the attribute in my code, and I'd expect admin to leave
away the Update/create option in this case.

Since this is in the admin, there's a hook especially for this 
-  ModelAdmin.get_form(). This is a method that you can override in your own 
ModelAdmin subclass - it's passed the request so you can check the value of 
request.user and return the appropriate form. See the code in 
django.contrib.admin.options.

standalone session checking

[Brian Craft]

I'm trying to implement a stand-alone python script to check a session
cookie for group authorization. I cribbed from the auth and session
middleware, so I could take the sessionid from the cookie, look up the
session, look up the user, and get the list of groups.

This all basically works, except for the very first time a session is
seen. The first lookup always fails. I know the session is good (a
call to a django view via @login_required, for example, works fine).

I'm expecting this is some problem with a cache, or evaluation order,
such that my script doesn't have the latest info from the db until
I've queried it once. Anyone have a clue? Here's what the auth
checking routine looks like:


def authorized(session_id, group):
ss = engine.SessionStore(session_id)
session=ss.load()
try:
user_id = session[SESSION_KEY]
backend_path = session[BACKEND_SESSION_KEY]
backend = load_backend(backend_path)
user = backend.get_user(user_id) or AnonymousUser()
except KeyError:
user = AnonymousUser()
return user.groups.filter(name=group).count()


It's called from a "while 1" loop in a script that never exits. The
first time a session cookie goes through this routine, it always
fails. Second, and subsequent times work.

Re: Custom ModelAdmin form for distinct logged users

Hi hollando,

You can use proxy models. Refer to
>
> http://stackoverflow.com/questions/2223375/multiplue-modeladmins-views-for-same-model-in-django-admin
>

I can't set permissions for proxy models, i think because the table
auth_permissions doesn't have the proxy records.
That is, i have the Foo model and the FooProxy. Whe i loggin as superuser i
see both, Foo and FooProxy admin forms. But when i log as other user (supose
proxyuser), who only have the permission "Can change foo", only see Foo
admin forms.

How can i reach the way to login as proxyuser, and enter only to the
FooProxy admin forms?

Absolutley right. I have the option of encoding the data on the
frontend to be passed as a JSON value. Currently that is off; that is,
the flag to encode as JSON is false so the data is supposed to be
passed as a "regular" POST parameter set, even if it looks like JSON.

Did you tried un-encoding the JSON, like this:

from django.utils.simplejson import simplejson

data = simplejson.loads(request.POST['data'])
id = data['id']

Why on earth do you want to use __getitem__? That's an internal 
implementation detail, which you should never need to access in your code 
unless you're overriding something. POST is a dictionary-like object, which 
defines __getitem__ so that you can access it with the usual Python 
dictionary access: request.POST['data'], and so on.

Secondly, if I'm understanding what you have posted, `data` is not an 
element of the POST dictionary - it *is* the POST dictionary. So rather than 
trying to access `request.POST['data']['id']`, you should be accessing 
`request.POST['id']`.

request.POST parsing without form

[taso]

Hi,

I am using django strictly as a backend for data processing. As such I
am not using any forms or templates, just database tables as models.
The page is js driven and POSTing data is causing me some issues.

A user action triggers a POST that looks like:

action "update"
data{ "field1": 8,"id": 2 }
(copied from firebug)

When I try to parse the POST data I get errors on every type of method
I have tried. What I eventually would like to do is something like:

if request.POST.__getitem__('xaction') == 'update':
mydata = request.POST.__getitem__('data')
model_to_update = modelname.get(id=mydata['id']
for k,v in mydata:
setattr(model_to_update, k, v)
model_to_update.save()

However every time I try to parse the "data" POST values I get errors.
I wonder if I am missing some assumptions by not importing/using
forms, or if there is a standard method to iterate through the POST
data that I am missing. I have literally tried every \*get\* dict
method from the docs and all throw errors (.list() throws numeric
indicies errors, iteritems() throws not iterable, etc.)

Any thoughts?

Thanks
Taso

Dont "think". You do have the full traceback - which you didn't post
(you didn't post the full code neither FWIW) - so read it and you'll
know.

It would have helped if you'd posted your model. If your relationships are 
defined as null=True, then select_related() doesn't follow them unless you 
specify them explicitly.

Settings to Load CSS Files

[octopusgrabbus]

I am running Django 1.2.4 mod_wsgi. My admin site loads with its look
and feel. I am trying to add css to my application, which works fine.
I have looked through the docs, and cannot get a sample css file to
load. I would appreciate some pointers to get this working.

Here are the appropriate lines from the base template.




{% block title %}Town of Arlington Water Department AMR
System{% endblock %} 

   

Here are the appropriate lines from httpd.conf
DocumentRoot /usr/local/www/documents
AliasMatch ^/([^/]*\.css) /usr/local/www/documents/static/$1


Order deny,allow
Allow from all


Here are the appropriate lines from settings.py
# Main URL for the project
BASE_URL = 'http://localhost:8002'

# Absolute path to the directory that holds media
MEDIA_ROOT = '/usr/local/www/documents'

# URL that handles the media served from MEDIA_ROOT
MEDIA_URL = '/static/'

# URL prefix for admin media -- CSS, JavaScript and images.
ADMIN_MEDIA_PREFIX = BASE_URL + '/media/'

Re: account errors when create superuser on cygwin

[Bill Freeman]

Did you create a superuser when you originally ran syncdb?  If so, you
can work around the problem in the admin, logged in as that original
superuser, making additional superuser through the web.

Have you tried logging in as the "jack" user?  The fact that the name is
now already taken implies that something was written to the database.
You can also test for this in the shell, importing User from
django.contrib.auth.models and doing a get or filter with username="jack",
and then examine the object, say, by pretty printing it's __dict__.

The error is interesting, however.  I wonder if it's repeatable.  You can
rename (or remove) your database file, redo syncdb, then try the
createsuperuser.
If that fails in the same way, then we could start inserting pdb.set_trace(),
say, before line 200 of
/usr/lib/python2.6/site-packages/django/db/backends/sqlite3/base.py
and poke around inside the Database object there to see what file it's going
to try to open, etc.

Django cache created in one function not available to another?

[Lance Vick]

So I have a function that sets cache (and successfully outputs it):

def push_cache:
cache.set('foo_cache', 'FUBAR!!!')
foodata = cache.get('foo_cache')
print(foodata) # this works

However when I try to access that cache from within a view and
directly output it it returns None:

def fetch_cache(request):
cache_data = cache.get('foo_cache')
return HttpResponse(cache_data) #this does not work.


Am i misunderstanding something fundamental in how cache works?

I am using the memcached backend in django 1.2.3

use variable that is bound at an object's creation time at the object's creation time

[Santiago Caracol]

Hello,

my model Product has an attribute spelling_variants and a property
variants:

class Product(models.Model):
   canonical_name = models.CharField(max_length=200)
   spelling_variants = models.ManyToManyField(String,
related_name="product spellings", blank=True)
   ...

   @property
   def variants(self):
  variants = []
  for v in self.spelling_variants:
 variants += paraphrase(v)
  return variants

The code works, if product instances are first saved without a vaue
for spelling_variants and later modified so as to have some spelling
variants. When I add spelling variants at the time when I create a
product in the admin interface, I get this error:

Caught TypeError while rendering: 'NoneType' object is not iterable

I think the problem in these cases is that when Python tries to
execute self.variants() it does not yet have a value for
self.spelling_variants.

How can I make sure that self.spelling_variants has a value when
self.variants() is executed?

Santiago

Re: admin won't load revisited

I got the look and feel back by substituting this:

# URL prefix for admin media -- CSS, JavaScript and images.
ADMIN_MEDIA_PREFIX = BASE_URL + '/media/'

and yet the other value did work

ADMIN_MEDIA_PREFIX = BASE_URL + 'media/admin/'

Oh, well. Thanks for the answers.

Re: admin won't load revisited

[octopusgrabbus]

In addition, I can't get the built-in server to serve the admin's look
and feel. I see that as a good thing, because clearly it's a wrong
setting that affects both servers. Here are the settings again.

# Main URL for the project
BASE_URL = 'http://localhost:8002'

# Absolute path to the directory that holds media
MEDIA_ROOT = '/usr/local/www/documents/media'

# URL that handles the media served from MEDIA_ROOT
MEDIA_URL = '/media/'

# URL prefix for admin media -- CSS, JavaScript and images.
ADMIN_MEDIA_PREFIX = BASE_URL + 'media/admin/'

[hank23]

So in a case like this the value previously selected can't be put back
out to the screen when the errors are displayed, to avoid the user
having to reselect the same file again when he inputs the previously
missing data?

Re: What is a good app to use for a portfolio or images and videos?

[mongoose]

I downloaded the new django-cms and it's quite a great package. It
offers video and images plus many more plugins. It's overkill for a
smaller portfolio site but it offers everything.
Still just testing though, haven't had to edit much but think that
when I need to change things then the hard times will come.

I once changed my admin.py file and after reloading nothing had changed.
What did solve this issue was restarting the server or hard refreshing the page 
(Shift + F5  or something like that, depending on the browser you're using)
But I'm guessing you've already done that.

Re: Google maps

[Shawn Milochik]

Just do a Google search for the Google Maps API. It's the same regardless of 
whether you're using Django or something else to generate the HTML pages. You 
mainly have to write JavaScript.

Also, search github and bitbucket to see if someone's created and shared some 
code for Django to easily generate the templates and JavaScript for you so you 
don't have to write much other than some lovely Python.

Re: first time deploying django on apache with mod_python on fedora 8

[ashwoods]

is there any reason you are using mod_python instead of, say, wsgi?
modpython is deprecated and there are "better" alternatives.
id start with that. looking in apache logs to find out why you have
the 500 error might help.
(a hunch tells me it might be a python path error)

Re: How to format a datetime in a webpage?

"The time filter will only accept parameters in the format string that

  So, you need to use:

  instead of:
{{record.ComplaintTime|time:"Y-m-d H:i"}}

How to format a datetime in a webpage?

[Wayne Young]

Hi all,

I have come across an error when I tried to format a datetime in a webpage.
This the part of webpage:

{% for record in records.object_list %}
  
{{record.ComplaintPhone}}
{{record.CustomerName}}
{{record.ComplaintTime|time:"Y-m-d
H:i"}}
{{record.ComplaintService}}
{{record.ComplaintDetail}}
{{record.CustomerArea}}
{{record.IsSolved}}
{{record.SolveTime|time:"Y-m-d H:i"}}
{{record.SolveMethod}}
{{record.Username}}
{{record.Remark}}
{{record.Intime|time:"Y-m-d
H:i"}}
   
{% endfor %}

The "records" here  is a QuerySet came from view:

 records = Report.objects.order_by('-Intime').all()



I tested in shell:

>>>record = Report.objects.get(pk=1)
>>>record.ComplaintTime.strftime('%Y-%m-%d %H:%M')
'2011-01-28 15:29'

It showed correctly. Also the attribution of "SolveTime" and "Intime". But
when I used "record.ComplaintTime.strftime('%Y-%m-%d %H:%M')" in webpage, it
said "Could not parse". So I changed to use "time" filter as above. But now
it shows nothing in those three time fields. I do not know why. Would
someone pleased to tell where I am wrong?

first time deploying django on apache with mod_python on fedora 8

[n0h8dy]

Hi,

I'm trying to get my first Django app up and running on amazon ec2
fedora 8 instance on apache with mod_python. I've got mod_python MySQL-
python python-devel Django mysql-server installed.

I've got the homepage to show up, but its a very simple view that just
returns text. Anything more complex produces a 500 error. I don't have
any other views setup right now, but I need the admin to work, which
also current produces a 500 error.

I've got a basic django setup with one app inside of it that has
models and admin stuff.

This is what my httpd.conf file looks like:



  ServerName  first.django-app.com

  DocumentRoot "/sites/django-app"


  Order allow,deny
  Allow from all



  SetHandler python-program
  SetEnv DJANGO_SETTINGS_MODULE django-app.settings
  PythonInterpreter django-app
  PythonHandler django.core.handlers.modpython
  PythonOption django.root /
  PythonPath "['/sites','/sites/django-app'] + sys.path"
  PythonDebug On



  SetHandler None



  Order allow,deny
  Allow from all



SetHandler None




Any hints, suggestions, ideas on how to get this to work would be
great.

Geodjango: ogrinspect on a Postgis layer?

[Ryan Clark]

I'm interested in using the ogrinspect command to help build a load.py
file for bringing data from one PostGIS table (in a legacy db) into my
Django project's db. What I can't seem to figure out is how to write the
data source location for a PostGIS layer. Can it be done?

I tried the following:
ogrinspect PG:"dbname=xxx host=xxx port=xxx user=xxx password=xxx"
modelname --mapping
... but that doesn't really make sense since it is pointing to a
database and not just a single layer. 

Any advice? 

Thanks,
Ryan

Yes, that was the first 'file' in the pastebin. It has everything it
says I need. I've started branching from the tutorial to follow my own

That is correct.

You just have to remember declare managed = False ni API, and from my 
experience (working with legacy Oracle DB for a good while), it's better to 
pick only what you need.

One special note: Oracle DATE field stores both - date and time with resolution 
of a second. 

There is no equivalent field in Django. If you use date.DateTimeField you get 
all kind of nasty exceptions when working with this kind of a legacy data 
because DateTimeField expects to find TIMESTAMP type (date/time with resolution 
of a fractions of a second)

We've worked around this by declaring our own custom field.

contrib.messages and HTML5 browsing context

[Plovarna]

Hello,
I just read Messages documentation 
(http://docs.djangoproject.com/en/1.2/ref/contrib/messages/#behavior-of-parallel-requests),
 and in the "Behavior of parallel requests" section is this note:

"...Note that this is typically not a problem in most applications and will 
become a non-issue in HTML5, where each window/tab will have its own browsing 
context."

What does it exactly mean please? For example, If I have website in HTML5 and 
have opened several tabs pointing to same website, there is no problem with 
"shared" cookie between tabs? So if application in first tab set  message in 
cookie, this cookie will be hidden from other tabs?

Thank you for clarification

The "save def save(self, *args, **kwargs):" should not have the leading save.

I have to overwrite save() for each model? Or is there a generic way
to define save(), i.e. a way that I have to use only once -- in the
abstract base class?

class BMW(models.Model):
   ...
  save def save(self, *args, **kwargs):
do_something()
super(BMW, self).save(*args, **kwargs)

class Fiat(models.Model):
   ...
  save def save(self, *args, **kwargs):
do_something()
super(Fiat, self).save(*args, **kwargs)

The whole point of subclassing is that subclasses inherit models from the 
superclass. That's how the model save() method is definted in the first place, 
if you don't override it. What exactly are you having problems with?

Re: Django and Oracle XE - Empty models file

[Nathan]

Cheers for the reply. The database in question is a remote database. I 
presume by Django user that you're referring to the local user account? 
Otherwise the user credentials in settings should be adequate. 

I'm guessing the only resolution to this is to hand craft the models?

It seems that my problems were due to another mistake of mine. I was
thinking in a too complicated way. You are right: nothing has to be
done, just inherit. Thank you.

abstract base class and overwriting save()

[Jaroslav Dobrek]

Hi,

if I have got several models that have identical code, except for
their save method, how can I use an abstract base class for them? Will
I have to overwrite save() for each model? Or is there a generic way
to define save(), i.e. a way that I have to use only once -- in the
abstract base class?

class BMW(models.Model):
   ...
  save def save(self, *args, **kwargs):
do_something()
super(BMW, self).save(*args, **kwargs)

class Fiat(models.Model):
   ...
  save def save(self, *args, **kwargs):
do_something()
super(Fiat, self).save(*args, **kwargs)

Did you create a admin.py file in the application directory ?
Because the only thing I see is your settings.py file.
