Re: serving root from static

[Andre Meyer]

thanks a lot, Colin, i will contact the WebFaction guys for the apache
setup. they are always very helpful ;-)

HOWEVER: for testing purposes only, using only runserver and sqlite, how to
preceed for making this work?

*http://localhost:8000/ --> static/index.html (NOT a
template)
*http:// localhost:8000
myapp1   -->
myapp1/index.html (a template)
http:// localhost:8000
/myapp2   -->
myapp2/index.html (a template)
http:// localhost:8000
/admin   --> the admin
interface

how to get the first url work with runserver? i can only get it to render a
template, but not server up an html file from the static directory.

thanks again
André

It's a know problem, logged as ticket #6776. Fixing this is a blocker
on merging newforms admin, so I'd be expecting a fix sooner rather
than later.

The ticket has some patches attached; I haven't tried them myself, but
they might be worth a try.

If you want the cheap fix, you can hack the line in newforms-admin
that raises the exception. As I understand it, removing the exception
won't actually break anything - it just means that you won't be warned
if you register an application multiple times with conflicting
settings.

The other workaround is to be rigorous with your imports. The common
cause here is having references to

from myproject.myapp.models import MyModel

and

from myapp.models import MyModel

in the same body of code. This causes two separate imports, which
causes a clash on admin regsistration. If you are rigorous about only
using one form of import (I suggest the second), you can avoid a lot
of the registration problems.

Yours,
Russ Magee %-)

When I first noticed that mod_python didn't seem to spit out .pyc files,
I figured that this was a "feature" because of its one-time loading
nature. I kind of liked the concept because .pyc files seem like clutter
sometimes. Good to know that my assumption was wrong. I'm going to keep
my permissions the way that they are. :)

Django and mysql SET datatype?

[Silfheed]

Heyas

So we have a table which makes use of mysql's SET datatype to store
the status of a page ('active','inappropriate','optout') with the
status being any combination of the three.  This helps us keep the
complexity of our schemas down since we just need one column (rather
than 3 tables) to represent our status.  Unfortunatly, Django doesnt
have anything in django.models to handle sets.  It does have
CommaSeparatedIntegerField, but it means having to store ints rather
than more descriptive texts.

Does anyone else out there happen to be using mysql SET+django and
have an elegant method for handling the situation?

Thanks!

Choose the fields for inline editing

Hi,
I really like the inline editing option, but found that sometimes I

I guess there is a way to do this, but I cannot find it. Really
appreciate if someone can help me out.

Hi Andre,

You'll need to set this up in your apache configuration, and the part
that deals with serving static files is going to be independent of any
django code or settings.

You just need to change the DocumentRoot of your site to the "static"
directory where your index.html is located.  It sounds like you've
already got django set up to serve the "myproject" directories, so
you're pretty close.  Don't know how apache setup works at WebFaction,
but if you're having trouble you should post the relevant sections
from your apache configuration (if possible).

A quick read over the apache docs will explain this much more
thourghly than I did :)  If there's one concept to take away, remember
that if apache's serving a static file, apache handles absolutely
every step of the process, and if python/django got involved in any
way you'd lose the performance benefit of serving directly from from
apache.

Testing framework or model save behaves differently after qsrf merge?

[peschler]

I'm currently facing a weird problem with the testing framework after
updating to the latest trunk version of the newforms-admin branch. I
have written a small example and a unittest to explain the issue and
to show that there seems to be some sort of problem after the qsrf
merge. I'm not quite sure where the problem is - unittest or qsrf -
that's why i post.

Below are two simple models Vocabulary and Term. A vocabulary contains
terms. When a new vocabulary is created (saved the first time), it
automatically creates a root term for the vocabulary.
Both models overload the save() method.

Running the unittest given below with django 0.97-newforms-admin-
SVN-7233 all tests pass fine.

When running the unittest given below with django 0.97-newforms-admin-
SVN-7599 the tests give the following error:

==
FAIL: test_qsrf (nmy.qsrftest.tests.QsrfTestCase)
--
Traceback (most recent call last):
  File "/home/peter/src/nmy/site-packages/nmy/qsrftest/tests.py", line
27, in test_qsrf
self.failUnlessEqual(v.root, v.root.vocabulary.root)
AssertionError:  != None

--

I tried to track down the problem, checked my unittest, checked my
models - but the only thing I could find is weird: As soon as I
reference the ``vocabulary`` field in a term's save() method the test
fails. If I remove all references to the ``vocabulary`` field from the
save() method the tests pass fine.
I found that a simple read-only operation like print or even a simple
noop reference of the ``vocabulary`` field changes the behaviour of
the unittest.

--- qsrftest/models.py
from django.db import models

class Vocabulary(models.Model):
root = models.ForeignKey('Term', null=True, blank=True,
related_name='root_of')

def save(self):
"""When a vocabulary is saved and it has no root term, a new
root
term is created. This happens only the first time a vocabulary
is
saved.
"""
super(Vocabulary, self).save()

if not self.root:
self.root = Term.objects.create(vocabulary=self)
super(Vocabulary, self).save()

class Term(models.Model):
vocabulary = models.ForeignKey(Vocabulary)

def save(self):
 super(Term, self).save()

 # As soon as self.vocabulary is referenced here, the unittest

Since you're talking about the sqlite backend, did you try this on the

Django graphic designers

[Juanjo Conti]

I'd like to know if there is a community of graphic designers working 
with django. Maybe a website with resources (css, html tamplates...)?

I am writing a little personal app and it looks really ugly :)

One of my options is to hire a designer, but I would prefer to hire one

raise AlreadyRegistered

[Andre Meyer]

hi all

i was trying to write a little script to populate my database with test data
after i have rebuilt it due to model changes. it seems to work (set the path
and imports appropriately), but i get this infamous
django.contrib.admin.sites.AlreadyRegistered error when running the script.

is there any news on whether this error can be removed or is there a better
way to populate the database?

thanks
André

Re: serving root from static

[Andre Meyer]

thanks Jeff

yes, i had found this method of having django serve static content, too, and
know it is not ideal.

what i want is different: use apache for serving the static content at the
root of the site (defind in settings.py and urls.py) and have a couple of
django apps which are accessible just with simple paths. the urls are what
disturbs me, because i cannot get anything from just http://mysite.org/, but
instead need to access http://mysite.org/myproject.

again, the non-functional code (raises "TemplateDoesNotExist at
/static/index.html"
in views):

urls.py

urlpatterns = patterns('myproject.views',
(r'^$', 'home')

views.py

def home(request):
return render_to_response('static/index.html')

maybe use something like
return HttpResponse('/static/index.html')
but how?

Bug in sqlite backend? Custom query gives OperationalError

[Pong]

Hi,

what is wrong with this query?

user_id_tuple = (2, 3, 25, 15) # for example
cursor = connection.cursor()
cursor.execute(SELECT
week, year, SUM(data), SUM(data1), SUM(data2),
SUM(data3),
SUM(data4) FROM user_table
WHERE user_id IN %s GROUP BY week, year
ORDER BY year, week""" , [user_id_tuple])

Django gives me OperationalError when I try to run it. I tried the
same query with mysql on different server(same django version) and it
worked great.

Re: HELP: Foreign keys, models, and querysets

[Richard Dahl]

from:
http://www.djangoproject.com/documentation/db-api/
 Backward

If a model has a ForeignKey, instances of the foreign-key model will have
access to a Manager that returns all instances of the first model. By
default, this Manager is named FOO_set, where FOO is the source model name,
lowercased. This Manager returns QuerySets, which can be filtered and
manipulated as described in the "Retrieving objects" section above.
 The 'Django-y' way is to access the related fields through a related
manager.  In your case Books is related to Person via pid which should have
models.ForeignKey(Person), I assume it is in your model.  So you would just
get the books related to the person via:
p = Person.objects.get(pk=1)
p.books_set.all()

Also, generally in Django, you do not necessarily need to specify the id (a
field called id will be created for you) and people usually will give
related fields names that are more descriptive of the object accessed, i.e.
:

class Person(models.Model):
fname = models.CharField(max_length=50)
lname = models.CharField(max_length=50)

class Books(models.Model)
name = models.CharField(max_length=50)
person = models.ForiegnKey(Person)

as when you use it you are getting the related objects rather than just
related ids, but this is obviously a matter of ones personal taste.

HELP: Foreign keys, models, and querysets

[Huuuze]

I have the following models in my models.py file:

>> class Person(models.Model):
>>   pid = models.AutoField(primary_key=True)
>>   fname = models.CharField(max_length=50)
>>   lname = models.CharField(max_length=50)

>>   bid = models.AutoField(primary_key=True)
>>   name = models.CharField(max_length=50)
>>   pid = models.ForiegnKey()

In my views.py, I'd like to run a query that returns a list of people
and their books, where "st" are the "search terms" being passed into
the view:

>> results = Person.objects.filter(Q(fname__istartswith=st) | 
>> Q(lname__istartswith=st))

This only returns the "Person" object.  Is there a "Django-y" way to
have it return both associated objects?  From what I can tell, it
looks like I need to use "Person.objects.extra()" to tie in the
additional "where" statements.

I apologize in advance if I've missed something obvious.  New to
Django and just looking for help.

Re: Dynamic initialization of MultipleChoiceField

Yeah.. you are right.. you will have to initialize the superclass..

the complete code that i have used is something like this..

class TestForm(ModelForm):
   items = forms.MultipleChoiceField( choices = (), required
=
False )

I believe your problem is that support for hierarchies of subclassed
models is still in progress. Right now, using the admin on top of such

trying to modify admin

[Adam Fraser]

Hello,

I'm using Django to keep track hours spent working on "projects".  The
data model includes classes "Project" (name, description,...),
"Timecard" (user, date) , and "TimecardHours" (timecard, project,
hours).

With these models plugged in, I get a nice admin page for changing/
reviewing projects.  This includes a form for editing all of the
fields in a project (ie: name, description,...).  However, I would
like to be able to also see (not necessarily edit) 2 other things:

1: How much time was spent by each user on that project.
2: How much time was logged in each individual Timecard including that
project.

Could someone please give me an idea of what the best/easiest way to
go about this is?  Any suggestions would be much appreciated!

To give you an idea of what I had in mind.  I started modifying my
project class to have 2 new functions to give me summations of hours
by user, and hours per timecard:

def hours_per_person(self):
   '''Returns a dictionary keyed by username of how many hours each
user has worked on this project.'''
   userHours = {}
   for u in User.objects.all():
   userHours[u.username] = 0.0
   for h in TimecardHours.objects.all():
   if (h.project.id == self.id) and (h.hours > 0.0):
   for t in Timecard.objects.all():
   if h.timecard.id == t.id:
   userHours[t.user.username] += h.hours
   return userHours

def hours_per_timecard(self):
   '''Returns a dictionary keyed by "username [-mm-dd]" of how
many hours each user has worked on this project.'''
   tcHours = {}
   for t in Timecard.objects.all():
   tcHours[t.user.username+' ['+str(t.date.year)
+"-"+str(t.date.month)+"-"+str(t.date.day)+"]"] = 0.0
   for h in TimecardHours.objects.all():
   if (h.project.id == self.id) and (h.hours > 0.0):
   for t in Timecard.objects.all():
   if h.timecard.id == t.id:
   userHours[t.user.username+' ['+str(t.date.year)
+"-"+str(t.date.month)+"-"+str(t.date.day)+"]"] += h.hours
   return tcHours



...might there be a good way to use these functions to render to a
template?  I'm still quite new to Django so what might seem obvious to
others is still not quite obvious to me.

thanks much!
Adam

"more than 1 ForeignKey" error in newforms-admin

[Andre Meyer]

hi all

just a quick question to be sure:

is it on purpose that newforms-admin does not allow more than one
ForeignKey? or is it a not yet supported feature?

i have a model with a class that has a foreign key and a subclass that has
another. this works well for creating the database, but the admin does not
like it.

thanks for clarification
André

"Hello, " I'm getting a False from user.is_authenticated().

Here're some relevant snippets:

>From the login handler:

   uName = request.POST['username']
   uPass = request.POST['password']
   user = authenticate(username=uName, password=uPass)

   if user is not None:
  if user.is_active:
 login(request, user)
 return HttpResponseRedirect(next)
  else:
 message = 'Account Deactivated'


>From the index view handler:

user = get_user(request)

if user.is_authenticated():
message = 'Welcome back!'
else:
message = 'Welcome.'

What am I missing here?  The index() function is in a separate view
file; however even if I move it to the same file as the login handler,
I get the same behavior.  Do I need to do something beyond calling
login() to make the user persistant across all request contexts?

Thanks in advance for any info...

Re: ModelChoiceField option values

[Adi]

The text displayed in the drop down comes from the __str__ method of
the referenced model.
So, just implement the __str__ method in the model that your
ModelChoiceField references, and the display will show you that.

Re: Dynamic initialization of MultipleChoiceField

[Adi]

Another option would be to create a __init__ (self,choices=()) method
on form
Then in the method, assign
self.fields['items'].choices = choices

and when you instantiate a form, you can specify the choices
choices = [('1', '1'), ('2', '2')]
form=RecoverForm(choices)

Dynamic initialization of MultipleChoiceField

[puff]

I needed to create a dynamically initialized MultipleChoiceField.
Unfortunately, the Django docs when talking about initialize didn't go
into how to deal with MultipleChoiceField.  A bit of scratching around
didn't show a real solution although Getting dynamic model choices in
newforms (http://www.djangosnippets.org/snippets/26/) is useful.  I
did find a ticket (#5033: Dynamic initial values for
MultipleChoiceFields in newforms) that was apparently closed for
rather poor reasons.  Finally, I stumbled on this solution and am
posting it here in the hope that others can find it.

In the form:

class RecoveryForm( forms.Form ):
items = forms.MultipleChoiceField( choices = (), required =
False )

When it comes time to use it:
choices = [('1', '1'), ('2', '2')]
form = RecoveryForm( )
form.fields[ 'items' ].choices = choices

Problem solved.

That said, I'm new to Django and VERY new to newforms so there may
well be a better way.

Re: Django and i18n

[Taevin]

Forgot about this for a while... Thanks for that, though.

In reading through the code on that site, I came across the
translation.activate function which is exactly what I needed. Now,
instead of forcing a page refresh, I can just do:

from django.utils.translation import activate

and then just call:
activate(session_language_code)

Thanks again!

That helped a lot, actually, to bring that particular page times down.
It was in the 2 second range.
The thing is, when I say painfully slow, I'm talking from 20--60
seconds from click to page render. It varies alot -- sometimes it
really flies, but when it's slow, it's really, really, really slow.

foreign key and verbose name?

[pihentagy]

Hi all!

In the docs here:
http://www.djangoproject.com/documentation/model-api/#verbose-field-names

Each field type, except for ForeignKey, ManyToManyField and
OneToOneField, takes an optional first positional argument — a verbose
name. If the verbose name isn’t given, Django will automatically
create it using the field’s attribute name, converting underscores to
spaces.

Is there a good reason to handle the verbose name differently in these
cases? (Is there a chance it will behave as expected, like other field
types?)

thanks

Painfully slow... why?

[[EMAIL PROTECTED]]

I'm trying desparately to figure out why my django sites are so slow.
Using the statsmiddleware, I'm seeing numbers like this:

Stats: Total: 0.08 Python: 0.07 DB: 0.01 Queries: 6
Stats: Total: 0.48 Python: 0.37 DB: 0.11 Queries: 3
Stats: Total: 0.21 Python: 0.17 DB: 0.05 Queries: 32
Stats: Total: 0.27 Python: 0.22 DB: 0.05 Queries: 32

So first question... are those numbers acceptable? They seem to me
like they should be.
If not, where do I look next to hone in further on the bottlenecks.
and if so -- this is the big question -- then why is the site still so
damn slow?

"intro to django" script -

[Carl Karsten]

I want to make a http://showmedo.com "Getting started with Django"

I expect it to be about 5 min long.  The goal is not show someone how to be 
productive, but how easy it is to get started.

At most 1 min on install python, install django, make sure you can do python -c 
"import django" without error.

Then some magic, python manage.py runserver, browse, “Welcome to Django”

Then some more magic, syncdb, http://127.0.0.1:8000/admin/ "log in"

Then define a model, view, html, url pattern.  maybe even a public facing form.

I am a bit fuzzy on what is considered 'best practices' for the 2 magic parts. 
  I hear what the tutorial/book describes (django-admin.py startproject mysite; 
startapp myapp) isn't what the the pros do now, or at least what the pros would 
recommend.  What I haven't heard is an alternative.

I am tempted to show creating all the files by hand.  (I can't do it all in 5 
minutes, but some Julia Child moves and sped up video should make it faster 
than 
explaining what startproject and startapp do.)

Any suggestions?  Any writeups that cover this?

It isn't clear if you are actually encountering a problem or just
anticipating one.  I have no experience with Oracle, but it would seem that
the "naming issues" note here:

http://www.djangoproject.com/documentation/databases/#naming-issues

indicates that the developers of the Oracle support were aware of this issue
and dealt with it.  Are you running into a problem with this method of

I've just added some docs about this [1]. You will need to dump both
parent class and child class. If they're in separate applications,
that means dumping both applications (or parts of both applications,
as appropriate).

When fixtures are reloaded, all the fixtures you load in a single
loaddata command are loaded inside a single transaction. Referential
integrity (when it's supported by your database) isn't checked until
the end of the transaction, so the order of creation internal to the
transaction doesn't matter. As a result, all the following:

loaddata all_data.json
loaddata parents.json children.json
loaddata children.json parents.json

will all be equivalent.

There is, of course, once caveat to this - if you're using MySQL with
InnoDB tables, all bets are off. InnoDB has referential integrity, but
it doesn't defer to end of transaction, so creation order becomes
important. This is a known bug, but one that is impossible to solve in
a generic fashion at our end - we need MySQL to fix their referential
integrity implementation. MyISAM tables aren't affected - they don't
have any referential integrity, so no checks are ever performed.

Re: Multi-table Models and Fixtures

[Greg Taylor]

Wonderful, I'll be able to test this pretty extensively tonight.

Since I don't think it's documented either way, is there a particular
procedure I should abide by when dumping/reloading fixtures for the
parent and child models? In my case, the parent is in one app, and the
child is another. Do I dumpdata for both of those apps and load them
in a certain order, or just dump for the child class that inherits
access to all of the fields and re-load that fixture?

Thanks again, this will get my project back on track!

OK; committed as [7600]. Let me know if you continue to have

Trouble trying to use formtools.preview.FormPreview

[shabda]

I am trying to use formtools.preview.FormPreview after reading
http://www.djangoproject.com/documentation/form_preview/ and am
getting weird errors.
This is what I did,

1. Have a form called AddReviewForm which is working as expected.
2. Created a class
class ReviewPreviewForm(FormPreview):

def done(self, request, cleaned_data):
import pdb
pdb.set_trace()
3. In my urls.py added this line
url(r'^post/$', ReviewPreviewForm(AddReviewForm),
name='reviews_preview'),
4. Changed template to post the form to '/post/'
5. Now I am expecting that the preview should appear on form posting,
but I am getting exception with traceback,

Traceback:
File "C:\Python25.1\lib\site-packages\django\core\handlers\base.py" in
get_response
  82. response = callback(request, *callback_args,
**callback_kwargs)
File "C:\Python25.1\lib\site-packages\django\contrib\formtools
\preview.py" in __call__
  31. return method(request)
File "C:\Python25.1\lib\site-packages\django\contrib\formtools
\preview.py" in preview_post
  58. f = self.form(request.POST, auto_id=AUTO_ID)

Exception Type: TypeError at /reviews/post/
Exception Value: __init__() takes at least 4 non-keyword arguments (2
given)

What am I doing wrong?

If you want, you can pre-compile everything as described at

   http://effbot.org/pyfaq/how-do-i-create-a-pyc-file.htm

which shows you can issue

   bash$ cd ~/code
   bash$ python -m compileall .
   [output]

which will compile each .py file into a corresponding .pyc file 
within the current directory and subdirectories.  I believe the 
Debian variants (others may as well) do this in the system 
directories upon installation so users don't have to recompile 
all the system libraries.

The time saved is minimal, but there's no harm in preemptively 
compiling your files.

You'll need to use some sort of rich text editor.  I've used

Text Formatting

[yanksluvr7]

Is there a way to make a django page so you can copy and paste text
into the page and have it keep its original formatting? Everything I
have found makes it copy as plain text, so any spacing, bullets, bold,
italics, or anything else is lost.

I don't think it will be faster.  Django normally runs as a long-standing
process (either inside Apache or as a standalone process, depending on the
deployment model you've chosen).  So, unlike ordinary CGI scripts, your
Python bytecode will not need to be generated except for the very first time
that your code is loaded.  Once it's up and running it will already be in
memory so it won't need to be reinterpreted.

I personally don't think the trade-off is worth it here.  You're giving
Apache write access to your source code (which may not be much of a security
risk relative to other things like the fact that Apache has access to your
database, but it is definitely a blurring of privilege boundaries), and
you're not getting any long-running performance benefit from it; only a
slight initial load benefit.

Thanks a lot !

I changed the user information in apache2's conf file, and now it's
OK!

I think this way, apache could be a little more faster. Am I right?

Hi Jeffery, bacccr, Julien, chefsmart & Garrett,

Thanks for all your responses. All the suggested methods are suitable 
for one time migration. Actually I am planning to migrate from VB to 
django in phases. So I may have to update data many times. i.e first 
export a few tables (doing some re-arrangement). After it settles down, 
export few more tables, as well as the new data entered in the phase I 
tables through the VB app. Basically one-time-export-of-tables will not 
work for me. So, if only I can access 'ms access' tables through python, 
I can write a few functions to check if the data has already reached 
MySQL table,  if not add it. The actual .mdb files are in a Windows box, 
so if the setup will require a Windows box it is okay, but it will be 
convenient if I can copy those .mdb files to my linux box, do the 
initial developement and testing and finally point the functions to the 
original .mdb files.

In short I am looking for a way to read(/write) tables in a .mdb file, 
through python.

Any pointers?

Thanks for your time once again

Ganesh

problem with mod python: can not import base64mime

[zekUs]

Hi,

I have djangp-svn installed (revision 7574) on an archlinux system.
for testing i created an empty project with: "django-admin.py
startproject deneme". when i run the test server i can see the default
welcome page of django.

then i installed mod_python (v 3.3.1) on apache (2.2.8.2). i compile
it from source. without any errors. i configure httpd.conf and test
the installation via mod_python.testhandler. there is no problem.

so the problem is then i try to access the empty project i created
above i get an error message: "ImproperlyConfigured: Error importing
middleware django.middleware.common: "No module named base64mIme" "
i did not touch any of the default project files and on test server no
problem. but with mod_python pfff.

here is my location directive in httpd.conf:

SetHandler python-program
PythonHandler django.core.handlers.modpython
#PythonHandler mod_python.testhandler
SetEnv DJANGO_SETTINGS_MODULE deneme.settings
PythonDebug On
PythonPath "['/home/zekus/devel'] + sys.path"


any ideas?

I think I have it pretty much under control. I'm just finessing some
test cases at the moment. It turns out there are actually a couple of
related problems - too much data was being serialized, primary keys
were missing a few critical annotations, and the save process was a
little too enthusiastic about creating new parent instances. However,
I think I've got a solution now; a little more testing, and there
should be something in trunk. Watch this space. :-)

RE: Problem with admin (urls)

[Fred Reillier]

Hello. I had the same problem a few days ago (i'm just discovering Django…)
after installing v 0.96. It seems to be a problem with the installer (two
folders not copied during the process : "admin/templates"  and
"admin/media"). 

 

To make things work, I had to copy manually the folders from the Django
Archive to the following locations : 

 

python/libs/site_packges/django/contrib/admin/templates
python/libs/site_packges/django/contrib/admin/media

 

On my Macbook, everything works perfectly now.

 

I found the solution on the page below. Just read the thread to find
indications related to your OS (the place where you should copy the folders
is not the same if you are on Windows or Linux or Mac):

Problem with admin (urls)

[Nader]

Hello,

I have a question. I have started a new project.

This is my "urls.py" file :

from django.conf.urls.defaults import *

urlpatterns = patterns('',
# Example:
# (r'^nadc/', include('nadc.foo.urls')),

# Uncomment this for admin:
(r'^admin/', include('django.contrib.admin.urls')),

)

But If I request the admin page ("http://localhost:8000/adim; I get
the next message:

Request Method: GET
Request URL:http://145.23.236.80:8080/admin/
Exception Type: TemplateDoesNotExist
Exception Value:admin/login.html
Exception Location: /data/cesar/home/Python-2.4.4/lib/python2.4/site-
packages/Django-0.96.1-py2.4.egg/django/template/loader.py in
find_template_source, line 72
Template-loader postmortem

Django tried loading these templates, in this order:

* Using loader
django.template.loaders.filesystem.load_template_source:
* Using loader
django.template.loaders.app_directories.load_template_source:

Would somebody tell me what the problem is ?

Regards,
Nader

oracle-django problem

[Harish]

hi friends

 i have a django application, which works on postgres as back-end.
now i want to migrate the application  back-end  from postgres to
oracle.

The problem i am facing is that, the existing data table names  in
postgres is too long
(basically  the table name is a combination of application name and
class name), which is not allowed
in oracle. (using oracle 11g) Basically oracle only allows 30
character as table name.

I am looking forward for any solution to my problem


regards
Harish Bhat

why my django site doesn't create .pyc file?

[pength]

I have justed built my site on slicehost. Alhough my site is running
properly, I found if I update any  file (.py file, of course), it
never recreate the .pyc file. Actually, if I delete any .pyc file,
then it will never appear.

I think there's something wrong with my site config, can anyone give
me any hint?

I am using nginx as front proxy server and static file server, apache2
and mod_python as backend.

Thanks!

Re: How to execute function dynamically?

[David.D]

I made a mistake! I use 'extra_context=locals()' in my generic view.
Now no problem.

Thanks very much.

Re: Importing data from 'MS Access' .mdb files

[Garrett Garcia]

Ganesh,

I just had to tackle the same problem in a django project.  I'm sure this
isn't the best solution but it works if you don't have access to a Windows
machine.  Download and install the mdb-tools package:
http://mdbtools.sourceforge.net/  In my app I run the mdb-export program
from python and save the output to csv files.  I then use python's csv
libraries to read in and manipulate the data and save it in the correct
format using the django models API.
