So, friends,
This etherpad is in comet (java) and can anyone tell how to integrate etherpad, keeping it as it is, with other django apps???
Some iFrame ideas??? Please file-in your views.

django, postgresql and eliminating duplicates

hi,

I have a model which allowed duplicates to be entered. Subsequently it
was decided to add a unique_together constraint and make the necessary
change in the db structure. Postgresql of course will not make a
unique_together constraint if there are duplicates. Since this is one
off, I wrote a script to eliminate duplicates, the script worked, but
psql is still not accepting the constraint saying there *are*
duplicates. The script is here:

def getdups():
mems = Member.objects.all()

for mem in mems:

dte = datetime.date(2009,1,1)
tod = datetime.datetime.today()
while ((dte.year != tod.year) and (dte.month != tod.month+1)):
if
Scoringrecord.objects.filter(member=mem,scoredate=dte).count() > 1:
for x in
Scoringrecord.objects.filter(member=mem,scoredate=dte)[1:]:
x.delete()
dte = dte+datetime.timedelta(days=1)
return 1

In the admin.py file, under the class whose number of rows you want to
display - use "list_per_page"

class MyModelAdmin(admin.ModelAdmin):
list_per_page = 10

There is no "global" default that I have been able to find. I simply
set a constant in the admin.py file (say DEFAULT_ROWS = 12) and then
in each class I use:
list_per_page = DEFAULT_ROWS

Accessing foreign key fields

class Article(models.Model):
author = models.ForeignKey(Author)
title = models.CharField(max_length = 100)

(assume an article can have only one author)

article = Article.objects.get(title="Django is awesome)

if I need only author id, I can access author id as 1)
article.author_id or 2) article.author.id

I prefer first article.author_id as it requires less db lookup and
hence better performance.

Any reason to use 2nd way over 1st.

( I understand this approach only works for id and not for say author
name)

Re: Model Question

I'm not sure about your first question; I've never tried overriding a field in a subclass.

For your second question are you trying to check on the whole query set, or an individual model instance?

If you're checking on an individual model instance, you can use hasattr() like:

if hasattr(instance, 'field_name'):
# do stuff

Otherwise, the way you specified it is pretty much the only way I know how to do it. I made it a method on my model that looks like the following:

def get_field_names(self):
return [field.name for field in ModelName._meta.fields]

You would call it by instantiating a 'blank' instance of the model:

fields = ModelName().get_field_names()

Re: Number of Django powered sites?

I've found that using "django tutorial" and "django documentation" in
google insights/trends does a pretty good job of filtering out the
namespace noise. You can also append tutorial or documentation to the
names of other frameworks to get an idea of relative trends.

Re: Foreignkey troubles : some key look ups give me a ValueError: invalid literal for int() with base 10 error

I posted this question as a ticket :

kmtracey suggested the fix ( http://code.djangoproject.com/ticket/15513) which is to use the ForeignKey.to_field to specify the column in the Parent table that the relation is mapped to.

I am copy-pasting his comments here:

The cause of the exception you are seeing is that per your Django models, the target column of the ForeignKey field in your Child model is the primary key field of Parent, not the ssn field. Primary key field of parent is an integer, so attempting to lookup a non-integer value raises an exception.

In order to tell Django that the target column for the ForeignKey field in child is the parent's ssn field, you need to specify to_field='ssn' on that ForeignKey definition. See: http://docs.djangoproject.com/en/1.2/ref/models/fields/#django.db.models.ForeignKey.to_field

Note though that your existing table definitions don't meet the requirements for a ForeignKey field here, because the Parent ssn field is not unique. Django's ForeignKey is a many-to-one relation, so the target column must be unique. See #11702. If you are not actually creating the tables via syncdb you may not initially see any error related to this failure to meet the requirements for a ForeignKey -- but if in fact you have duplicated values in that target field, you may see errors later on.

Your Django models also show evidence of bug #5725. The max_length values for all your CharFields are 3x higher than they should be. Easiest fix is to manually correct them to be the right value.

Hi Everyone ,

I am using the svn version of django to write a django app to hook into a legacy database.
I am having some problem with querying by a ForeignKey which is not a Primary key. The sql datatype for the foreign key is VARCHAR(256) , but lookups only succeed with integer fields . The original database has integer and non-integer values for this field. Only Non-int fields throw a ValueError when I try to use the filter in django.

here is my test case:

I have a Parent table and a child table. Both parent and child have their own primary keys. The child table has the parent attribute called ssn ( in SQL a VARCHAR(256)) as a foreign key constraint. The SQL for my test case is given below.

After creating this test database and then creating my models with django manage.py inspectdb and running syncdb , I get the following behavior (see below). The ForeignKey Lookup succeeds only for int fields but fails for non int fields. The test db and models.py is pasted below.

What am i doing wrong

Re: DatabaseError at / no such table: cms_page

I suspect you had already done a syncdb before creating that field. If yes, the database would not create it just like that.
When I had similar problem, here's what I did.
I removed the database file from my project root and then ran a syncdb again. It worked.
There's a price to pay however, you would lose everything in the database and you have to repopulate again.

There is no admin.py file in this project.

Well, why not? That is the cause of your problem. Putting admin registration in models.py will frequently lead to this error, which is the whole reason for having a separate admin.py.

That isn't the correct syntax for unicode string literals. What you
are trying to do should look like this:

if lang_string[0] >= u'\u0590' and lang_string[0] <= u'\u05ff':

(See http://docs.python.org/reference/lexical_analysis.html#strings
for all the details on \u, \U, \x and their friends)

Testing just the first character of the string may or may not work for
general input; that depends entirely on your problem (and your users).
If it were me, I would define a utility function like this:

def char_is_hebrew(char):
return char >= u'\u0590' and char <= u'\u05ff'

and then test all of the characters in the string, either with

if any(map(char_is_hebrew, lang_string)):
<some character is in the range>

if all(map(char_is_hebrew, lang_string)):
<every character is in the range>

Re: sqlite path

Make sure the directory containing your sqlite database is writable by the user your web server is running as. sqlite occasionally creates some temporary files in the same directory side-by-side your actual sqlite file.

More info. This isn't a django issue after all. I just tried a simple
select * using the sqlite shell and got a disk io error. If I move the
database to my home directory, the select works, so there's something
weird going on with the mounted disk where my django app lives (a
netapp device).

sorry for the noise,

python mysqldb installation problem

OS: Ubuntu 10.04
I am learning web developing with Django.I downloaded and installed
python-mysql but i couldn't connect.I think problem is database
settings.
Here is the process:

django-admin.py startproject mysite #creating a project and a mysite
folder

files in 'mysite' folder:
/__init__.py
/urls.py
/manage.py
/views.py
/settings.py

Then i edited the 'settings.py' file.There are alse database settings
in it.

Here are the settings:

DATABASE_ENGINE = 'mysql'
DATABASE_NAME = 'mydb'
DATABASE_USER = 'me'
DATABASE_PASSWORD = 'pwd'
DATABASE_HOST = ''
DATABASE_PORT = ''

then i write the codes below with terminal:

python manage.py shell

from django.db import connection
cursor=connection.cursor()

Then the error occurs as:

Traceback (most recent call last):
File "<console>", line 1, in <module>
File "/usr/lib/python2.5/site-packages/django/db/backends/mysql/
base.py", line 99, in cursor
self.connection = Database.connect(**kwargs)
File "/var/lib/python-support/python2.5/MySQLdb/__init__.py", line 74,
in Connect
return Connection(*args, **kwargs)
File "/var/lib/python-support/python2.5/MySQLdb/connections.py", line
170, in __init__
super(Connection, self).__init__(*args, **kwargs2)
OperationalError: (2002, "Can't connect to local MySQL server through
socket '/var/run/mysqld/mysqld.sock' (2)")

It looks like that error occurs from DATABASE_HOST but i don't think
so because when using MySQL DATABASE_HOST may be left blank

Django include templates problem, from 0.96 to 1.2

Hi folks,

I using google app engine, in 0.96 I have no problem to include a
template as following

{% include "../header.html" %}

However, in 1.2 the code above not functioning??

Any idea?

Re: jquery document ready aggregation

If I'm remembering correctly, the context is composed of a list of dictionaries.
When you reference a value, the layers are searched, most recently added
first, until one is found that has the variable you want (or not). When you
set a variable, it always uses the top layer, even if the same variable exists
in a lower layer.

Various things add layers, for example, the "with" and "for" tags. When you
pass the corresponding end tag, the layer is discarded. So if some of your
domready invocations are within one of these constructs, and your
domready_render is outside, it's not going to see the stuff that was defined
inside.

A way of handling this is to make your renderer a tag that requires an end
tag. It can create the variable (probably pushing it's own layer onto the
context stack) in its opening tag, making its value a mutable, such as a
python list. The domready tags would then append to the list. This avoids
making a new version of the same variable in some inner layer because
you only read the variable, you don't set it: it still has the
original list, it is
the list that is modified. The render renders its template contents, then,
as a final act, emits the javascript in its variable. This is like it being
rendered at the end tag.

You might want to make both tags accept a string argument to use as the
variable name, just in case you discover a need to nest them, say to
accumulate stuff that must occur in an order different from that in which it
appears in the template. You could, of course, default the variable to a
standard name.

new project settings file not found

this is a first for me. i set up a project like i normally do and get
things set up... run syncdb for the first time for the project. Havent
had this happen before and things seem to be working on other projects
just fine. I've even go so far as to comment out the handful of apps.
I presume there

now, is there a requirement that the apache stuff be set up to run
syncdb? that is the only thing i can think of as i just set up the
subdomain and http.conf for it on the server. doesn't seem to make
sense to me that that would be the case though...

file/directory permissions are the same as my other projects as well

Re: urls.py usage

There is no admin.py file in this project.
Model.py file contains:
from django.db import models
from django.contrib import admin
class BlogPost(models.Model):
title = models.CharField(max_length=150)
body = models.TextField()
timestamp = models.DateTimeField()
class Meta:

admin.site.register(BlogPost, BlogPostAdmin)

Re: GENERIC VIEW CONCERNS AND EXPLANATION REQUIREMENTS

Short answer: yes.

The generic views are there for a reason, to provide a simple implementation of most generic operations like detail views, listings ...

A complete different things is the "if I have to", you don't!

One thing is DRY other is use the tools and possibilities that the framework gives allows you to, depending on the case you might find some limitations on the usage of generic views. It's all about "generic" you need your views to be!

hi, I converted my original mysql database to sqlite3. Firefox sqlite
extension can view the database and it looks okay. It looks like the
Django settings are okay to me--here they are:

DATABASES = {
'default': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': '/Apps/web/myproject.sqlite',
'USER': '',
'PASSWORD': '',
'HOST': '',
'PORT': '',
}
}
And here are the dir permissions of /Apps/web:

drwxrwxrwx 4 tiarno wheel 4096 Feb 25 14:54 ./
drwxr-xr-x 8 tiarno wheel 4096 Feb 23 17:24 ../
drwxrwxrwx 5 tiarno wheel 4096 Feb 25 15:16 django/
drwxr-xr-x 2 tiarno wheel 4096 Sep 17 15:45 home/
-rwxrwxrwx 1 tiarno wheel 1588224 Feb 25 13:51 myproject.sqlite*

I run validate and get '0 errors found'. I run syncdb and get this:

python manage.py syncdb
Traceback (most recent call last):

Django+ oracle, working with apache(mod_python, wsgi) and in runserver, ora-03114 in fastcgi

Hi
my application works fine in apache as mod_python and wsgi, also work
great when I run manage.py runserver
but I have to move it on nginx.

so I run it by 'python2.6 manage.py runfcgi host=127.0.0.1 port=9001 --
settings=settings'
and it works fine until it have to connect to the database (oracle in
my situation) and i get " Unhandled Exception",
when I checked logs its what I found :
"
OperationalError: ORA-03114: not connected to ORACLE" while reading
response header from upstream, client: 192.168.1.105, server:
localhost, request: "POST / HTTP/1.1", upstream: "fastcgi://
127.0.0.1:9001", host: "192.168.1.50", referrer: "http://
192.168.1.50/"
"

ORACLE enviroment vars are set correctly, what can I do to fix this?

That you have duplicate registration of one model in your admin.py
somewhere (I believe, I may be wrong).

What does this message (it appears after web browser entering) means:

AlreadyRegistered at /blog/
The model BlogPost is already registered

CSRF token can be only rendered in CSRF protected views

I was not able to describe my problems to ticket on first attempt, so
I try here before creation of another ticket.

We use CSRF protection on almost all POST requests, but we encountered
some limitations of CSRF protection as currently implemented in
django.

- You can not render POST form in unprotected views, not even if user
has CSRF cookie already set.
- If you render such form, you will always end up in CSRF failure
view, because input with csrf_token has value set to some replacement
string
- I had to overcome this problem by copying part of middleware
that sets csrf cookie to request.META. Alternative solution is to call
CSRF check manually and throw away the result
- Call CSRF check manually (not middleware or decorator) is not very
handy, code for that looks like

result = CsrfViewMiddleware().process_view(request, lambda:
None, None, None)
# if None is returned, than it is OK
if result:
# Store data back to session to prevent their loss
return result

This call is not very pretty, especially because second argument is
only used to check if view was exempt from CSRF protection and last
two are mandatory for process_view method of middleware and are not
used in csrf check.

My questions are
- is correct my assumption that rendering CSRF token in unprotected
view should be possible or am I missing something
- is reasonable requirement to call CSRF check manually
