For me it worked reliably.  However, I needed Unicode regular
expressions, which didn't work with MySQL (a known issue).

Tschö,

That is not true.

Global variables at Python module scope will last for the life time of
the process.

That said, you must still be careful about using them because server
may be multiprocess and/or multithreaded, both of which causes issues
with doing it that way.

Have a read of:

  http://code.google.com/p/modwsgi/wiki/ProcessesAndThreading

as it says a bit about that.

Apache service runs as a special user, are your directories/files
actually readable to others. If they aren't Apache/mod_wsgi may not be
able to access them.

And what official documentation told you to do that. You should not
fiddle either of those. Doing so it just likely to cause problems,
although in this case, because Apache runs as special user, not likely
to stuff things up if you only did this for your own user specific
settings. Put it all back to what it was originally.

Above is wrong because that isn't where you have it installed.

This is not a valid Windows path, shouldn't have a slash before drives
specifier.

This looks okay and should work.

Did you restart Apache after making changes to be sure it was picked
up. Although WSGI script file will be reloaded when using mod_wsgi and
it is changed, if you have made a number of accumulated changes the
internal state of the interpreter could have been messed up.

Please do not go posting a tutorial. Half the problem is that people
who don't really understand what they are doing post their tutorials
and the net gets polluted with them and people can't find the real
documentation in the noise. End result is that they use some ones
partially inaccurate instructions and just get confused, as seems to
be the case for you.

How to tidy up data returned by raw sql has u'blahblah'

[adelaide_mike]

My raw sql returns a list of data very nicely, except that character
cols have data surrounded by u'', and dates have datetime.date
(2009-01-01) etc.

In my newbie innocence I have not discovered how to remove these
extras.  Any clues?

Thanks

Mike

same here.  my sites aren't so busy, but they do run continuously for months on 
RAM-limited VMs,  I'ts Ubuntu stock packages too.

All my text data on  MySQL is UTF-8 and haven't seen any problem at all.  maybe 
the leaky part isn't exactly the Unicode support but the translation between 
unicode and other encodings.  I always make sure that it's UTF-8 all the way, 
with no translation at any point (i don't see any value on latin1 or other 
limited kludges)

I've got several MySQL servers in production. I haven't seen any
memory leak problems from a site that does baseline traffic of 3-4
hits from the Google bot per second, 24-7, plus user traffic. This is
using the stock version of MySQLdb from Ubuntu 8.10.

I'm storing lots of unicode content, and I haven't seen any problems
storing or retrieving that content.

Getting value from form in formset

[ristretto.rb]

Hi,  I fear that I just haven't found this in the docs yet.  But, here
goes

I'm using a formset to list out a number of text box fields.   The
initial number varies based on a couple of factors.  But, never
grows.

The formset has initial_values.  In the template, I have to preset the
values in a jQuery block.  I can look loop through the forms, and
print the html text boxes fine, but I don't know how to get the
integer value of the field, so I can set up the jQuery control.

I'm thinking I may have used this formset feature for the wrong
reason.  But, I wanted to get the validation, and other support.

Any thoughts?

thanks
Gene

ModelForm's is_valid() returns False, but I don't know why.

[George Laskowsky]

I have the following code (simplified):

# models.py

class Historico(models.Model):
 fechaCreacion = models.DateTimeField(auto_now_add=True)
 fechaModificacion = models.DateTimeField(auto_now=True)

class Meta:
abstract = True

class Categoria(Historico):
nombre =models.CharField(max_length = 20)
descripcion =   models.CharField(max_length = 50, blank = True,
verbose_name = 'descripción')

def __unicode__(self):
return self.nombre

class Meta:
ordering = ['nombre']

# forms.py

class CategoriaForm(forms.ModelForm):
class Meta:
model = Categoria

# views.py
[lots of code, variable 'data' is loaded with data from a file]
 form = CategoriaForm( initial=data , prefix=str(idx) )
 if form.is_valid():
[do something]
else:
   [do another thing]
[/lots of code]

The webpage shows the form populated with the data, BUT, is_valid() always
return false. I don't know what fails to validate, form.errors is empty.

Thanks!

P.S: thanks Margie for the last help.

Just a quick suggestion - if you're going to go to the trouble of

Formwizard and subforms

[Gee]

Hi,

I am trying to build a formwizard that includes a manytomany
relationship on one of the steps and I am stuck on to implement the
manytomany. The models are, (only for step in question)

class Person(models.Model):
  name = models.CharField
  addr   = models.ManyToMany(Phone)

class Phone(models.Model):
 PHONE_CHOICES(('H','Home'),('W",'Work'),('M','Mobile'))
 phone= models.CharField(max_length=10)
 phoneType = models.CharField(max_length=1, choices=PHONE_CHOICES)

The models are setup this way on the premise that more than one person
could have any number of the same phone numbers.

What I need to do is have a select box on the form that shows the
phone choices and when one is selected an option to add a new line to
the form that to retain that phone information for that type.

Any help would be greatly appreciated.

Thanks
Andrew

ManyToMany Model.py and the shell..

[rh0dium]

Hi Guys,

First post to the group I did do a search and came up dry.  I also own
the django book (Forcier,Bissex,Chun) and they don't explain how to do
this.  In short I can't figure out how to progmatically add a data via
a python shell script to the ManyToMay model..

--- models.py ---
from django.db import models
from django.contrib import admin

class Client(models.Model):
  client= models.CharField(max_length=256, primary_key=True)
  access= models.DateField()
  submitOptions = models.CharField(max_length=256)
  update= models.DateField()
  def __unicode__(self):
return str(self.client)
admin.site.register(Client)

class Change(models.Model):
  """This simply expands out 'p4 describe' """
  change= models.IntegerField(primary_key=True)
  client= models.ManyToManyField(Client)
  desc  = models.TextField()
  status= models.CharField(max_length=128)
  def __unicode__(self):
return str(self.change)
admin.site.register(Change)

Here is what I have which works but I don't know how to add the
ManyToMany.  I can't seem to figure out how to progmatically call it.
I know the row in SQL exists.

---  massImport.py ---

# Assume the client "clientspec" exists.  I know how to create that if
neeeded.

changes = [ { 'change': 123, 'desc': "foobar", status': "foobar",
client': "clientspec", }]

for item in changes:
  entry = Change(
change= item['change'],
desc= item['desc'],
status= item['status'],
# client= Client.objects.filter(client=item['client'])
)
  entry.save()

---  massImport.py ---


Can anyone show me where the error of my ways is.  I would really
appreciate it.

Thanks!!

Re: Don't understand ModelForm

[ristretto.rb]

What I'm doing now is

#  TEMPLATE
{% if modelform.instance.id %}
  
{% endif %}

#  The POST part of the view method

pk = request.POST.get('pk',None)
if pk:
  model = models.House.objects.get(pk=pk)
  modelform = forms.MyModelForm(request.POST, instance=house)
else:
  modelform = forms.MyModelForm(request.POST)

Anyone else use this approach?

Re: Don't understand ModelForm

[ristretto.rb]

This is an excellent thread.  I came here with the same questions as
Marc.  My revelation seems to be that forms are for data, and saving
is control.  And these two have separate concerns/goals.  Such that
fields shouldn't be in forms for the sole reason to make control of
the form function properly.

So you can put the id in you forms with a hidden, or in the action=""
attribute, or using some sort of JavaScript, or whatever.  So, I
understand that the key should be controlled outside the scope of the
Django form support.

But, I wonder if something like {{ form_set.management_form }} for
formsets could be used here.  Perhaps something like
{{form.indentifier_key}} on a template in the form could by default
write out a hidden field of the pk of the instance.  It would just be
shorthand for putting the instance in the context, and typing 

But, it could make your view work like this, so you don't have to
query up the model instance yourself.

  f = your_modelform(request.POST)
  f.instance #  would be the read from the DB and set for you.

Re: how much python do i need to know to learn/use Django?

[snfctech]

@Peter:  Thanks for the dissenting opinion, Peter.  (And thanks for
the vote, Cliff.)

Actually, Peter, I find your points the most convincing of all.  But
especially in light of the fact that I've just discovered web2py, it
seems to make more sense for me to focus on getting a good grasp of
Python, rather than diving to quickly into Django.  I'm probably going
to have to evaluate both of these Python frameworks simultaneously.

Re: digg style pagination

[Benjamin Wohlwend]

Hi,

On Aug 14, 8:54 pm, sniper  wrote:

Like everything else that comes with Django, the admin app is open
source, so nothing stops you from having a peek. This particular
functionality can be found in django/contrib/admin/templatetags/
admin_list.py, line 28[1]. The template tag has some admin-specifics
in it, you'd have to copy the template tag and adjust it. Or, and this
is probably what David so eloquently suggested, you could use one of
the countless digg-style paginators for Django that float around the
net. I'm quite fond of this[2] one because it extends the built-in
pagination facilities instead of completely reinventing the wheel.

Kind regards,
Benjamin

It actually ended up being my CodeWidget being wonky, or some weird
assumptions that FormWizard makes, I'm not sure what's at fault here.

My CodeWidget class is trying to mimic the serial number entry for a
software product.  4 sets of 4 digits, here's the code:
http://dpaste.com/hold/80733/

It expects 4 different fields to be in the POST data, code_part0,
code_part1, code_part2, and code_part3.  value_from_datadict assembles
them into the full serial number, which looks something like this:

---

... which is what you get if you access form.cleaned_data['code']

This means that in the FormWizards sanity check at the end when it
tries to revalidate all the forms, it just passes
"code=---" into the form as the data instead of the 4
fields it's looking for, and the form no longer passes is_valid().

I made a simple check in value_from_datadict:

code = self.data.get(name, None)
if code: return code

I'm not sure if that's the correct way to go about it, but it's working for now.

How good is Django's MySQL driver & its unicode support?

[Continuation]

I came upon this blog post:
http://lucumr.pocoo.org/2009/1/8/the-sad-state-of-mysql-python

It doesn't exactly have good things to say about mysql-python (aka
MySQLdb) which I believe is the MySQL driver used by Django. Among
other things memory leak was mentioned as a significant issue.

If you use MySQL with Django, how is your experience with the MySQL
driver? Any memory leak or other issues?

Also one of the commenters of that blog post mentioned that unicode
support has been removed from mysql-python. Is that true? Have you
been able to store & retrieve unicode content in MySQL using Django?

Thanks

Modification difference in Adm and user accounts

[David]

Hello,

Here is what I meet. In "Admin" account I can see all users' records.
If I modify a user's record, say "Peter", then I can see Peter's
modified record immediately if i refresh my browser.

However, If I login into "Peter" account (as a user) and do this
modification, then I can not see the new modified record immediately
no matter how many times I refresh my broswer. I need to wait a period
of time (3 or 5 minutes?) before I can see this modification.

This is the same browser. It's IE.

Anybody knows how to handle this problem?

Thanks so much.

digg style pagination

[sniper]

I am trying to do pagination. Just wanted to know if there is a
shortcut to show digg style pagination or i have to write my own?
I am asking this because in the admin page, the list page uses digg
style paging.

Display pictures located in MEDIA_ROOT ?

[Katja]

Hello,

I am storing some images in my MEDIA_ROOT and have now the problem
that I am not exactly sure how I can use them on webpages later on.

settings.py
MEDIA_ROOT = '/data/zooscan/'
MEDIA_URL = 'http://MYSERVER/mediafiles/'

In apache2.conf I added the following:
  
SetHandler None
  

  
SetHandler None
  

In url.py
(r'^mediafiles/(?P.*)$', 'django.views/static.serve',
{'document_root':settings.MEDIA_ROOT}),

So how do I know call my images?
I have tried various versions e.g.
http://MEDIA_URL/zooscan/profilepics/PIC.png

What am I missing?
Or am I completely on the wrong way?

Thanks!

Re: Override __init__()

[Léon Dignòn]

Yeah! this is working very well!

Now my last question. How can I change the initial-value of first_name
and last_name I defined in my class (look at first post)? I have  to
do it in the __init__() because I need some values of instance.

Thanks

Good OneToOneField design?

[John M]

Hey everyone,

I'm trying to use the 1-1 fields, and love the examples and how it
works, once it's created.  However, I'm having trouble determining
when in my code to create the actual instance of the 1-1 object.

What I really want is for the save() method of the 'master' side of
the model to create the 1-1 record, and that's easy enough, but if I
then start putting the 1-1 model into the admin interface, it seems to
error out when I try saving new records in the admin interface.

Am I off in thinking the creation of the 1-1 record should be done in
the save() method or should it be somewhere else in a view?

What I'd love to hear are peoples examples of how they used 1-1 fields
and implemented them in their code.

Thanks so much

John Matthew

Form Wizard won't proceed past the second step

[Adam Olsen]

I've got a FormWizard with two forms in it.  It validates the first
form correctly, and proceeds onto the second form, but when I click
submit for the second form, it does no validation and just jumps back
to the first step.  I get no errors in this process.

My urls.py looks like this:

urlpatterns = patterns('sendoutcards.retail.views',
(r'^register/$', forms.RegistrationWizard()),
)

My FormWizard, two Forms, and the templates involved are here:

http://dpaste.com/hold/80601/

What am I doing wrong?

I second this one and if you don't have any knowledge of functional

Re: Problem running django through fcgi on shared hosting

[Oli Warner]

If you're just trying to host stuff you're developing (for yourself) you
could host it locally, either just using the dev server or using a
lightweight server like lighttpd.

If you actually want to deploy the sites, I'm still no use... But Bluehost
do offer pro-rated refunds (if you're 2 months into a 12 month contract, you
get 10 months' worth back). The setup fee is non-refundable AFIAK.

I'll stop being useless, step back and let anybody who might actually know
how to fix this, fix it. Best of luck Jonas.

put the logic in the view function (or maybe in the model!) and hand a

Is there a way to combine ifequal with ifequal/if?

[realfun]

Hi,
I have met the situation like "if A==B or A==C: doSomething...", or, "if
A==B or C: doSomething..."

I found it's hard to express in Django template, and small though, so no
meaning to write it as a filter.

Current I did a redundancy way:

{%ifequal A B%}
blabla
{%else%}
{%ifequal A C%}
blabla
{%endifequal%}
{%endifequal%}

this is fare more complex than it should be, it even dup the code!

Is there an easy way or hidden feature that could make a simple solution?

Re: Problem running django through fcgi on shared hosting

[Oli Warner]

I apologise in advance for a reply that isn't going to seem immediately
useful.

Don't host django sites on shared systems that don't wont help users host
their sites with them. Seriously. I've tried both Dreamhost (did it!) and
Bluehost (failed miserably). You spend hours, if not days, hacking around
and you end up with something that is far from ideal.

With a host that does care about Django, you copy your site onto their
server and it runs.

If you can afford it ($10/month) I'd seriously suggest a low-end VPS. They
make life even easier.

Problem running django through fcgi on shared hosting

[Jonas Obrist]

I try to get django (1.0.2) to run on a shared hosting (with python 
2.5.2) through fcgi (with flup 1.0.2).

I've written a very simple app to test this:

/myproject/settings.py: http://dpaste.com/80556/
/myproject/urls.py: http://dpaste.com/80557/
/myproject/home/views.py: http://dpaste.com/80558/

I use this script to run it:

django.fcgi: http://dpaste.com/80559/

with the .htaccess:

http://dpaste.com/80560/

Problem: I get an error when calling the page (using 
http://www.ojii.ch/projectsj/django.fcgi):

Traceback (most recent call last):
  File "django.fcgi", line 9, in 
WSGIServer(WSGIHandler()).run()
  File 
"/home1/ojiich/lib/python2.5/site-packages/flup-1.0.2-py2.5.egg/flup/server/fcgi.py",
 
line 114, in run
  File 
"/home1/ojiich/lib/python2.5/site-packages/flup-1.0.2-py2.5.egg/flup/server/threadedserver.py",
 
line 84, in run
socket.error: (22, 'Invalid argument')

Which of course raises a 500 error.

Anyone got any ideas how to fix this? Been trying everything I could 
think of and followed two different guides:

I strongly disagree.  The thing to remember is that Django is just
Python applied to web programming.  Knowing Python better, and
understanding the quirks of the language and why they are there, will
serve you better when programming a Django app.  Django is a supremely
Pythonic approach to web applications (not the only such, to be sure).
 The framework developers use the language fluently.  The better you
understand the language, the easier you will find it to understand
Django.  The choices made in designing Django will be obvious, or at
least more clear than they would have been otherwise.

You are more likely to reach your goal of having a working Django site
sooner if you have a better understanding of the language than if you
concentrate on Django and skip the subtleties of the language.  Yes,
Python is designed to be easy to learn and easy to read, but
understanding the possibilities inherent in the language will help you
grasp more of Django more easily than if you just dive into web
programming.

Listen to the instructor, he's not wrong.

OK, so you've made some changes.  Are you saying that has had absolutely no
effect on the results?  "nothing of these is working" doesn't really tell us
if anything has changed or if you are still just not getting what you were
expecting.

Your previous debug information showed that admindocs was not listed in
INSTALLED_APPS, now that it is there you should, at a minimum, be getting
different debug information.  Also, attempting to go to /admin/ should now
take you to the admin main page and should not be resulting to any attempt
to render an admin docs template.

If indeed you are seeing no difference then somehow these changes you have
made are not being used.  Are you using the development server?  Apache?
Something else?

If you are seeing something different if would help people help you if you
would share details of the behavior you are seeing now.

Re: how much python do i need to know to learn/use Django?

[Oli Warner]

I'd take the Django course.

Python is possibly one of the easiest languages to step into. You will
see new constructs, you will see funny-looking methods of doing things,
but they all make relative sense.

I would suggest going out and getting the Python Pocket Reference
(O'Reilly - Mark Lutz).

It's a tiny book but you can seriously learn all the Python you'll need
to develop Django apps just flicking through it when you need to know
something.

Having a window into #python or #django on freenode might be an idea too
=)

Re: admin running in dev mode (manage.py runserver) ignores MEDIA_URL

[physicsnick]

You have to use the --adminmedia option to runserver; there's no other
way. Even if you serve the media yourself, the admin media overrides
your urls.py. The developers seem to have stopped listening to
complaints about fixing this:

Re: how much python do i need to know to learn/use Django?

[snfctech]

And I guess the answer to the title of the post, according to you guys
is:

"All you need is previous programming experience and a Python
reference book.  Learning some Python basics before diving into Django
is probably a good idea, but you don't need to spend weeks on it or
take a bootcamp/course."

Re: how much python do i need to know to learn/use Django?

[snfctech]

Thanks for all the helpful replies, django-users group!

I've got:

- Java and C++ coursework
- a little professional Java, Perl and Tcl/Tk experience (off and on
over several years)
- 1 year large Servoy project (like a Java based Filemaker)
- about 2 years full-time PHP (including one MVC project with
CodeIgniter)

I tried picking up the "Agile Web Development with Rails" book a
couple years ago (without studying Ruby).  I went through the demo app
well enough, but hobbled along with a first pet-project that left me
scratching my head a bit.  Maybe I just didn't put enough time into
it, or maybe it was like what TiNo (above) was saying - had problems
distinguishing between Ruby classes/conventions and the Rails ones,
which just added to my brain load and slowed me down when looking at a
page of Ruby/Rails code.

I spoke with the instructor of the Python and Django courses, and he
said I should take the Python and learn Django online, if I had to
choose (especially since my project may require deviation from the
Django ORM into SQLAlchemy, etc.).  My only reservation being that I
want to start using Django fast to actually build stuff.  And, it
sounds like you guys are saying that taking the Django course should
be okay since I have previous programming experience in other
languages (just brush up and take a book).

Normally I wouldn't even bother with programming bootcamps like this -
but we have an education budget available, and I imagine having a
Python or Django expert by my side for 5 days could be quite helpful
at times.

So, still not sure what I should do, but thanks for the tips.

One way to describe a "project" is "web site", or "web application".  
You have a top-level urls.py, a top-level settings.py, and in your 
settings you are specifying which "apps" are to be used in this site.  
An app, then, does NOT need to sit in the project directory.  Instead, 
it can and should be a Python package and should be made available to 
your "project" via being on the PYTHONPATH.  That way, the app is 
available to any other projects at the same time.

For more on this structure, read James Bennett's _Practical Django 
Projects_, and his blog entries on the subject.

As others have stated, feel free to break out models.py into 
../models/__init__.py and ../models/, ../models/, 
etc.  However, one major point to keep in mind is that if you restrict a 
given "app" to providing a single function (or small set of intimately 
related functions), and break other functionality into other apps, then 
the models.py for a given app will generally never get too terribly 
big.  This separation and modularization is part of the success factor 
for Django -- there are hundreds, perhaps thousands of reusable apps you 
can plug in to provide functionality for your site.  And when you start 
thinking that your models.py, or views.py, is getting too big, you 
should probably start asking yourself if you split a related set of 
functionality out into its own app.

Re: Using Psycopg2 on Windows

[James Walmsley]

Just in case anyone happens to be still wrestling with this problem. 
There was something wrong with the latest build of Psycopg2, which 
stopped it all working.

Simply install an earlier version, (2.0.10 works great), even with 
PostgreSQL 8.4.x series.

Portal Apps

[Joshua Williams]

Quick question in regards to building portable apps:  Should an  
application rely on the app being on the PYTHONPATH to work properly?   
That is, is having a app directory on the PYTHONPATH so common, is  
should just be assumed this is done when you install a new app?

Would form validation work?
http://docs.djangoproject.com/en/dev/ref/forms/validation/

You can check the form and then return the form with errors, so everything
is validated.

Hope that helps,

problems with reverse lookup of cache_page view

[Robert]

I am having a problem with cache_page and url resolver, my problem is
that django doesn't resolve correctly my url to the correct url when
the view is cached with cache_page decorator.

In fact this is in the context of sitemaps contrib, what I am doing is
the following:

(r'^sitemap.xml$', index, {'sitemaps': sitemaps}),
(r'^sitemap-(?P.+)\.xml$', cache_page(sitemap, 24 * 60 *
60), {'sitemaps': sitemaps}),

then I get the following response in sitemap.xml:



http://localhost:8000/barcelona/sitemap.xml


http://localhost:8000/barcelona/sitemap.xml

...


Which is incorrect because should have the diferent url for each
section sitemap-.xml. I think this is related to an issue
closed for python 2.4 but I am experiementing this problem also with
python 2.5.2, anyone else has this problem ? my django version is the
revisio 9080

Re: Problem with getting setting up apache server for django

[NiJoMi]

Installed Python 2.6.2 for all users and apache server failed to
configure mod_wsgi, so I installed
mod_wsgi-win32-ap22py26-3.0c4.so and renamed it mod_wsgi.so and apache
configured the mod.

however I am still getting 500 Internal Server Error

No you don't want to. And even it's possible in theory, you shouldn't 
even consider that option.

Store value in session?

First at all, your variable would only live time of request (meaning 
from the moment URL is parsed and reponse is sent to your browser). What 
  happens to your "global" after that? It wouldn't exist on next request.

Rather than listing all the key word arguments (kwargs) like that, you
are better doing it like this:

import logging # probably a better way than writing to debug.txt, but
clearly it is personal choice

def __init__(self, *args, **kwargs):
instance = getattr(kwargs, 'instance')
logging.debug("First name: %s" % instance.user.first_name) # I
like to know what it thinks it is printing!
logging.debug("Last name: %s" % instance.user.last_name) #
obviously you can change str if you like
super(ProfileForm, self).__init__(data, *args, **kwargs)

I don't know if this will fix your problem (hard to say without
visibility of the view), but it may be that you have forgotten one of
the kwargs. If you want to add extra parameters, or set them to
specific values you can still do this before calling init.

HTH,
Em

FilePathField refresh

[captainmish]

Hello
Im trying to implement an "alternative upload" method for getting big
files into my django app - and was hoping to allow users to scp/rsync
etc files to the server, then use FilePathField to browse them and use
them to make objects with FileField.
The files are all shown in the path specified and work fine, but the
problem comes in seeing new files - the server needs to be reloaded
before any new files are shown in the filepathfield select...
Is there a workaround for this, or an alternative way of doing it?
Thanks,

Override __init__()

[Léon Dignòn]

Hi,

I try override a ModelForms init to claim the variable instance. After
that I call super.__init__().
It's almost working, but there is no form shown in the browser.  Any
ideas what might be wrong?

class ProfileForm(ModelForm):
first_name = forms.CharField(required=False, max_length=30)
last_name = forms.CharField(required=False, max_length=30)

class Meta:
model = UserProfile
exclude = ('user',) # User will be filled in by the view.

def __init__(self, data=None, files=None, auto_id='id_%s',
prefix=None, initial=None,
 error_class=None, label_suffix=':',
empty_permitted=False, instance=None):
f = open('debug.txt', 'w')
f.write("%s \n\n-\n\n" % instance.user.first_name) # Bob
f.write("%s \n\n-\n\n" % instance.user.last_name) # Marley

Re: how much python do i need to know to learn/use Django?

[Alexandru-Emil Lupu]

HI!
personally i have started using Python / Django around 2 weeks ago. I do not
know very much of it, but on a long term, my situation looks like:
3 years pascal Programming
5 years php Programming (1 with symfony framework)
2 weeks of Python / Django

I cannot say that i have read any material, but i have had a look into the
django book (if you have some programming MVC experience, you will find the
tutorial straight forward). and every time i have a question or so, i check
the book. I know .. is not recomended to do so, but you will be able to
start your project, and make a small progress, and start learning Django, by
doing it.

Alecs

I would second this. but also if you do the django course, take a
python book with you - then if you don't get something you can just
look it up in the book quickly (the python website would also do, it
just depends on whether you prefer to learn from books or the web).
Remember, the people teaching the django course will know python, so
will be able to give you a bit of guidance if you get really stuck,
but if you go on the python course, it won't necessarily help get you
up and running with django. The poll tutorial on the django website is
brilliant for showing the different features and getting you started
though.

If you have no programming experience and don't know python, the
django course will be a lot to take in at once.

admin running in dev mode (manage.py runserver) ignores MEDIA_URL

[Aljosa Mohorovic]

settings.py:
MEDIA_ROOT = "%s/media" % PROJECT_ROOT # set to media folder in
project root
MEDIA_URL = '/media/'
ADMIN_MEDIA_PREFIX = '/media/admin/'

urls.py
if settings.DEBUG:
  urlpatterns += patterns('',
(r'^media/(?P.*)$', 'django.views.static.serve',
{'document_root': settings.MEDIA_ROOT, 'show_indexes':True}),
  )

example:
PROJECT_ROOT/media/admin/img/admin/default-bg.gif exists but
PROJECT_ROOT/env/lib/python2.6/site-packages/django/contrib/admin/
media/img/admin/default-bg.gif is used instead.

when i use mod_wsgi to run this instead of manage.py runserver it
works as expected.

anybody knows how to force django admin when running in dev mode
(manage.py runserver) to use images from MEDIA_URL and not images in
django/contrib/admin/media?

It looks like the first part of an error response, filtered through
the django-logging middleware. Are you using django-logging?

I don't really think this is a useful question on its own.  A more
appropriate question would be "How much programming experience do I
need?".  If you have prior programming experience in another language
then I'm sure you'll find Python quick and easy to pick up.  In that
case going through the tutorial and playing around with it in an
afternoon should be enough to prep you for a Django book or course.

If you have no programming experience at all then out of the two
options it would be better to take the Python one.  Any pure Django
course would assume a certain amount of Python knowledge.  But even if
you take a Python course you need to know if the particular course
assumes prior programming experience of some kind of is more of an
"Introduction to Programming Using Python".  If you take a Django
course with no programming experience at all then you will be wasting
your time.  If you have experience in some kind of programming and
then take a Django course with no Python experience then you might be
able to get by.

Wayne

I would make sure you know a little Python, especially about classes,
classmethods and inheritance. Otherwise you might have a hard time making
distinction between Django functions and methods and built-in Python stuff.
But it shouldn't be to hard to learn both at the same time.

Re: how much python do i need to know to learn/use Django?

[djangonoob]

hey, just some personal tips from my personal learning journey.

I started off by learning the basics and syntax of python ( such as
how the functions look like,
the for loop, ifs else etc cos it is slightly different ). I read teh
book : Dive into python which is available free online.
I only read teh first 4 chapters. (i have some C programming
experience )

Afterwhich i went straight into the online djangobook ( the first 7 or
8 chapters to understand
how it works ).

It took me about 2 weeks ( i spent about 2 or 3 hours per day ) to
learn what is going on,
and by than i could already write some decent projects already using
Django.

The good thing by not going to the book camp is that u control your
pace.

Yup hope this helps.

Also keep in mind that models are just Python classes. So to split up your
models in different files, you just set up a directory like this:

project
| - app
  | - models (dir)
| - __init__.py
| - post.py
| - comment.py
  | - urls.py
  | - ...
| - anotherapp..

Then you can import your models as: from app.models.post import Post
or you can import them in you __init__ file and import them as normal
# __init__.py
from post import Post
from comment import Comment

# somewhere else:
from app.models import Post, Comment

Or use a decent versioning system...

Re: Problem with getting setting up apache server for django

[Graham Dumpleton]

Reinstall Python with latest Python 2.6 version and this time select
option that says 'install for all users' and not the option 'install
only for current user'. That should fix the problem.
