Re: getting set up on osx for first app!

[js]

Hi again,

OS X has pre-installed apache and Python, but you still have to
install Django yourself.
Get the latest version from http://www.djangoproject.com/download/
and try installing.

Thanks

Re: setting up apache on OSX

[js]

Hi,

If you're not planning on setting up productioin environment,
but just for testing/developing, you don't have to use apache.
Django development server is good enough your porpose.

If you want to learn how to set up secure apache,
you might want to check http://httpd.apache.org/userslist.html

setting up apache on OSX

[newbiedoobiedoo]

I started working to install apache on OSX, so I can use django, and I
realized I'm in over my head.  I don't want to make stupid errors in
file sharing
and firewall settings, leaving my computer open to attack.

Is it safe to do this?
Is there anyone out there who would be willing to help me go through
the mundane
but treacherous part of setting up the system preferences and etc.  I
am a programmer, but a sys admin, I'm not.

I'm not sure what I can offer in return...   If you live in Berkeley,
I can offer
to trade coffee/dinner/housework?   I could offer some of the DVDs I
made on
do-it-yourself healthcare...

Thanks!

A nicer way to phrase that would be "you should consider upgrading..."

I compiled 3.3.1 and installed it over the top of the CentOS installed
one and that error did go away, thanks.

I'm still getting the transient errors mentioned in my OP though.

needs some template logic or model logic

[Milan Andric]

Hi I'm working on extending a forum app to allow for email
subscriptions.
http://code.google.com/p/django-forum/issues/list

I'm running into one fairly simple issue and thought someone might be
able to enlighten me.

Here's part of my model: http://dpaste.com/34401/

And here's the template logic: http://dpaste.com/34400/

{% for t in threads %}

{{ t.forum.title }}
{% if t.sticky %}Sticky {% endif %}{{ t.title }}{% if t.closed %}
(Closed){% endif %}


{% endfor %}

user.subscription_set.all isn't specific enough because I actually
need to query on user AND thread.  So does is there no easy way around
a template tag?

Thanks for you suggestions,

Milan

Re: Getting development environment configured

[Brandon Taylor]

Hi,

That doesn't seem to want to work for me. Since I've been able to get
mod_python to run my pages, I'm halfway there. Now I just can't get
images to show up in my pages.

My website directory structure is:

/website1
/public
/images

/__init__.py, urls.py, views.py, etc

If I'm specifying multiple  in Apache, how can I tell
mod_python not to serve images, etc, for that particular location?

Specifically, let's say I have




...



...




What's the correct way to turn mod_python off for static content if
I'm specifying more than 1 location? But, more importantly, it seems,
is telling Apache what to consider the Website root, which in the case
of my folder structure, is "public".

Does that make sense? I don't want to have to hard code the path to
each image in a site, that's just not going to work at all.

Thanks,
Brandon

Django Connections

[Dave Fowler]

I believe I'm having issues with django connections.  I'm using EC2
with a remote mysql database and make about 6 queries per page.  There
is some latency due to the distance of the remote server.  Each query
takes about .038s to complete.

Pages take about 2 seconds to load however.  The person running my
database says that django could be dropping my connection, which means
each query actually takes longer than it reports?  Has anyone run into
this?  How could I verify that this is true or false?

Additionally, I wrote a custom query manager for one of my queries.
It opens its own django.db.connection.cursor() each time it is
called.  Is this bad practice?  Would this be using up my connection
queue?

Thanks

Problems validating data

[Maykel Moya]

I'm using Django trunk r7047. This is my code

prj/validators.py
===
from django.core.validators import ValidationError

class StringLengthIs(object):
def __init__(self, length, error_message=''):
self.length = length
if not error_message:
self.error_message = _("This string length must be %s.") %
length
else:
self.error_message = error_message

def __call__(self, field_data, all_data):
val = len(field_data)

if val != self.length:
raise ValidationError(self.error_message)

prj/app/models.py
=
from prj.validators import StringLengthIs

class Foo(models.Model):
name = models.CharField(validator_list=[StringLengthIs(6)])

prj/app/forms.py

from prj.app.models import Foo

class FooForm(forms.ModelForm):
def clean_name(self):
# This isn't run
pass
def clean(self):
# This is run
pass
class Meta:
model = Foo

--
when I save() a Foo instance StringLengthIs(6) is not run. Besides,
when I call is_valid() to a FooForm instance clean() is called but
clean_name() isn't called.

What I'm doing wrong?

maykel

Can't seem to get Q objects to work as I'd like...

[Oliver Beattie]

Hi People,

I'm trying to write a query using Q objects but I'm getting incredibly
frustrated with them. I'm afraid I don't know SQL so I wouldn't know
how to write the queries by hand! The query (using Q objects) I am
trying to construct is:-

media = media.filter(
Q(owner=requester) |
Q(user_permission__granted_to=requester,
user_permission__privilege__icontains=privilege) |
Q(group_permission__granted_to__members=requester,
group_permission__privilege__icontains=privilege) |
Q(tags__user_permission__granted_to=requester,
tags__user_permission__privilege__icontains=privilege) |
Q(tags__group_permission__granted_to__members=requester,
tags__group_permission__privilege__icontains=privilege)
)

I think most people would be able to figure out what I wanted there!
The SQL this generates can be seen at http://dpaste.com/34377/ if this
helps anyone. I'm running out of ideas of what to try next.

Can anyone help me? Is there another way I could go about this?

Any help would be appreciated immensely,
Oliver

Re: using mod_python to host several django apps on the same vhost?

Hey Charles, 

I believe you will find that answer specifically here:

"If you need to put two Django installations within the

you’ll need to take a special precaution to ensure mod_python’s code
cache
doesn’t mess things up. Use the PythonInterpreter directive to give

  Hi,
  
  I'd like to host several django
applications at http://foo.bar.com/x,
  http://foo.bar.com/y,
etc. Currently I'm managing them all in the same vhost, using Apache
locations to direct each URL to a different Django project. However,
this technique requires me to rewrite my urls.py to accept ^x/admin
instead of ^admin (which is bad and breaks portability). Is there a way
that I can use mod_python to proxy http://foo.bar.com/x/admin/ to
Django as /admin/ while still remembering which Django project it's
running?

Re: Getting development environment configured

[Brandon Taylor]

I'll just be glad to actually see my friggin' pages render, much less
actually getting it to a production environment. There's certainly not
the "instant gratification" with Django that comes with Rails, but I'm
all about using the right technology to fit the client's needs.

The main reasons I'm interested in Django are the built-in admin (dear
lord, if I never have to build another admin, it'll be too soon) and
hopefully a small code base. So much of my freelance work could be
made child's play thanks to the Django admin. Rails makes it very easy
to do RESTful controllers and shortens the dev cycle quite a bit, but,
I end up writing the same code, again and again.

Cheers,
b

auth/add/user error

[Narso]

Hi. Forgive my poor English

I think there is an error in the "admin/auth/user/add_form.html"
template, because it uses a form_url variable that does not exist. The
user_add_stage doesn't pass it.

Normally this error is not fire, the form's action attribute get
blank. But, when I set the TEMPLATE_STRING_IF_INVALID variable in the
settings file to:
   TEMPLATE_STRING_IF_INVALID = 'Variable "%s" out of context'
then the add_form's action fire a non matching URL.

How can I fix this problem

thanks

using mod_python to host several django apps on the same vhost?

[charles.wesley]

Hi,

I'd like to host several django applications at http://foo.bar.com/x, 
http://foo.bar.com/y, etc. Currently I'm managing them all in the same vhost, 
using Apache locations to direct each URL to a different Django project. 
However, this technique requires me to rewrite my urls.py to accept ^x/admin 
instead of ^admin (which is bad and breaks portability). Is there a way that I 
can use mod_python to proxy http://foo.bar.com/x/admin/ to Django as /admin/ 
while still remembering which Django project it's running?

Thanks,
charles

The admin application relies on, and thus requires, that
TEMPLATE_STRING_IF_INVALID be an empty string. As noted in the
documentation for this setting, changing it will cause things to
break.

Re: Getting development environment configured

[Brandon Taylor]

FINALLY, it works.

I guess the entire problem was that I had specified the website
directory itself instead of the PARENT of the website directory in the
PythonPath. Now I just need to tell Apache to not process anything
else with mod_python and I should be good to go.

Thanks Adam,

Re: how to get a queryset by a ManyToMany field

This definitely makes sense, I have made a view called

Re: Deploying django framework with site

[Corey Oordt]

Tim,

The django module just needs to be on the python path, which you can  
set in the mod_python configuration.

So you could do something like:

/My Site
   /myproject
  
   /site-packages
  /django
 
  

Shouldn't be to difficult as long as you put both /My Site/myproject  
and /site-packages on the python path.

Getting development environment configured

[Brandon Taylor]

Hello everyone. I'm sure this question has been asked a million times,
but I'm going to ask it again, because I'm starting to get *really*
frustrated with trying to get Django up and running.

I would like to use the built-in development server, as getting
mod_python and Apache configured is simply impossible from my best
estimation. I've followed every tutorial I can find on the Internet,
and after 3 days of restarting Apache, I still get the "Could not
import settings mysite.settings" error. Ugh.

So, chin up, moving on. Here is my website's directory structure:

/mysite
  /public
/images
/css
/javascripts

  /templates
public.html
home_page.html

views.py
settings.py
urls.py
__init__.py


When I start up the dev server using manage.py runserver, my
home_page.html template will render, but no images, no css, etc.

How can I:

1. Tell the development server what the root of the website is.
2. Where my images, css and javascript files are.

I have put: (r'^public/../(?P.*)$', 'django.views.static.serve',
{'document_root': '/public/../images'}),

in my URLconf, but, it's still not happy.

Can someone please, Please, PLEASE show me what I'm doing wrong? I've
been doing web development for 10 years using asp, asp.net, php, cold
fusion, rails and java, but for the life of me, I can't seem to get
Django to do what it's supposed to do.

I would very much like to learn and use this great framework, but so
far, getting out of the gate has been really tough and I'd really
appreciate some help. I'm in Austin, Texas, and if there's anyone
local that would be so gracious as to help me get started with some
face-to-face tutoring, I'd be more than happy to compensate you for
your time.

Kind regards,
Brandon Taylor

Regroup issue (in template)

[Kristian Øllegaard]

Hi there!

I've tried to use regroup, without any result. I've read the entire
documentation, and searched google for hours, but i can't find a
solution - to me it looks correct.

I've pasted the code here:
http://paste.ubuntu-nl.org/55244/

Included is models.py and the template file

the view is here:
navn = Klasse.objects.get(afdeling__iexact=afdeling,
aargang__iexact=aargang, klasse__iexact=klasse)
klasse = Klasse.objects.get(afdeling__iexact=afdeling,
aargang__iexact=aargang, klasse__iexact=klasse).id
lektier =
Lektie.objects.filter(klasse__exact=klasse).order_by('dato')

return render_to_response("homework/lektie_list.html",
  { 'object_list' : lektier,
'navn' : navn},
  context_instance=RequestContext(request)
  )

Thanks in advantage!

I wouldn't put it in a URLconf. URLconfs are supposed to be
"configuration", so putting logic there seems dirty (to me). From
there, though, it's a bit of a matter of taste: do you consider "books
by an author" to be model logic, or view logic?

For me, I'm usually guided by how I'll be using the query in question:
if it's designed to be accessed from non-view areas (template tags,
CLI scripts, etc.) I'll put it on the model, but if that particular
query is only used in some specific view, I'll leave it in the view.
Again, though, it's a matter of taste.

That won't work from what I understand of your model. If article_list
is a QuerySet, it won't have a .video attribute (that attribute
belongs to a single article.

Furthermore, this for loop wants to loop over all videos, but you said
you only wanted to show the first one.

>   
>   
>   {{ video.0.name }}, {{ video.0.url }}
>   

Here's a solution:

{% get_article_list as article_list %}
{% for article in article_list %}
{% displayfirstvideo article %}
{% endfor %}

The above assumes that you are trying to display the first video of
*each* article from article_list inside your main template.

Then, create a new template tag called displayfirstvideo:

@register.inclusion_tag('youtube-video.html')
def displayfirstvideo(article):
   video = article.video.all()[0]
   return {'video':video}

Note that this templatetag assumes you've got at least one video in
the article being passed as a parameter. I am sure you can refine that
if necessary.

Create a new template called youtube-video.html in your template path
with something like:


  
  {{ video.name }}, {{ video.url }}

Re: how to get a queryset by a ManyToMany field

[coldpizza]

Thanks a lot! Before posting I have spent over an hour reading and
rereading that particular page in the doc section and in the
Djangobook but still somehow the concept eluded me. I do admit though
that I do not have previous experience solving this sort of issues in
other languages. Maybe adding a real use case to the doc could make it
easier to grasp.

And other related question: where it would be more logically correct
to put this code? In URLConf as an parameter for the view, in a view
of its own, or in a method bound to the Book model?

Re: newforms validator_list

[lowshoe]

after digging around in the code, i found "SubfieldBase" at
django.db.models.fields.subclassing

the docs there say this:

"Add SubfieldBase as the __metaclass__ for your Field subclass,
implement
to_python() and the other necessary methods and everything will work
seamlessly."

so i created my own field-class, added the __metaclass__ attribute as
told above and overwrote the validate() method:

from django.db.models.fields import SlugField
from django.db.models.fields.subclassing import SubfieldBase

class UniqueSlugField(SlugField):
__metaclass__ = SubfieldBase

def validate(self, field_data, all_data):
# do validation here...


but this validate-method never seems to be called. if we could
owerwrite the validation method this way, everything would be fine,
because whe had finally access to both "field_data" and "all_data" for
validation again.

any ideas?

cheers, lowshoe

Re: how to get a queryset by a ManyToMany field

You'll want to more closely read the documentation on related object
lookups: http://www.djangoproject.com/documentation/db-api/#related-objects.

The short version, though, is this:

Given a author ID, to find all the books by that author you'd use::

Book.objects.filter(authors__pk=author_id)

Or, given a particular author object::

author.book_set.all()

(Where did "book_set" come from? It's automatically created on the
"other side" of the many-to-many relation you created from Book to
Author. You can change the name of that relation attribute using the
"related_name" option to ManyToManyField).

Jacob

PS: Also see Chapter 5 of the Django Book
(http://djangobook.com/en/1.0/chapter05/); it's got examples pretty
similar to what you're doing.

Displaying ManyToMany fields inside templates

[Martin]

This is probably very trivial question, though i can't figure it out.
I haven't found anything usefull in documentation, so i'll try my luck
here.

My model Article has a ManyToMany field called Video, which points to
a model Video. To make it simple, Article has many Videos.

class Article(models.Model):
   video = models.ManyToManyField(Video, blank=True, null=True,
filter_interface=models.VERTICAL)
   etc.

Then i'm trying to display only the first video in base.html (the main
html template) and all videos in article_detail.html. I can't figure
out how to display only the first video.. in detail, for loop works
ok.

This is the code i'm using in base.html (i use templatetag for
article, to display only ones that have video):
{% get_article_list as article_list %}
{% for video in article_list.video.all %}
  
  
  {{ video.0.name }}, {{ video.0.url }}
  

Is this the right syntax? If it's not, how would i display the first
video?
I really appreciate any help,

thanks, martin

You want to have a look at the request/response documentation, which
explains exactly why this is and exactly what you need to do.

javascript shortcuts on django templates

[Mihai Damian]

I'm following the official Django tutorial for ver 0.96. I got to the
part where the admin pages are generated and noticed that none of the
javascript helpers mentioned in the tutorial get displayed on my pages
(the date - time control, or the show link for collapsible fields,
etc.).

I use 0.96.1 on Windows and I had to manualy copy the media and
templates folders from the archive into site-packages\django\contrib
\admin to get the tamplates working in the first place (I'm not shure
if this is somehow related to my problem).

how to get a queryset by a ManyToMany field

[coldpizza]

Sorry if this is too trivial but I have looked through the docs and
could not find a clear answer.

Given that I have a Book model with a ManyToManyField called authors
how do I get all the books for a particular author? Each book may have
more than one author, so I cannot filter the books using the standard
methods.

My models are:
class Author(models.Model):
name = models.CharField(max_length=124)

class Book(models.Model):
title = models.CharField(max_length=124)
authors = models.ManyToManyField(Author)

If I got it right, according to the documentation to get to a 'child'
queryset I have to iterate with 'for each b in Book.objects.all()',
and then call the b.authors.all() on each instance in order to check
if a particular author.id is found in the authors queryset. But how do
I get the results as a queryset? I could not get this to work.

To get all the books for a given author.id, I have tried:

def books_by_author(request, object_id):
'''does not work'''
filtered_by_author = []
for b in Book.objects.all():
if object_id in [a.id for a in b.authors.all()]:
filtered_by_author.append(b)
return render_to_response('polls/book_list.html', {'object_list':
filtered_by_author,} )

But this, of course, does not work, because it returns a list and not
a query set. What would be a proper, nice solution?

How to use multiple selection with POST method

[MADDY]

I am building web application using Django+postgresql

Have an INSERT page with text fields, text boxes, dropdown menus and
LIST/MENU form elements.



Let's say, have 10 options in "select", and need to select some of
them, as user wants.

User can select, for example, 3 options (not need to be consecutive)
from 10 possible options using CTRL+mouse.

When form is submited in database I found only one of those 3 options,
the one at the bottom of 3 selected.

Always one that is at the bottom of selected 3 or whatever is
selected.

Why? There should be all 3 options in table of database, and in one
field of table.

I cannot find a way to resolve this issue.

ANY IDEA WHY IT SHOULD BE LIKE THIS?

ANY HELP WOULD BE APPRICIATED.

THANK YOU.

Re: resizing an image

[NickJ]

This code - 
http://www.aspandjavascript.co.uk/javascript/javascript_api/get_element_width_height.asp
- offers better cross-browser support.

However it may be better to get the image size server-side. Django
offers builtin methods on image fields to obtain the image width and
height; alternatively, you can store the data in the database. See the
model-api on ImageField for details.

Re: Dumping objects in templates

[NickJ]

I don't know of anything out-of-the-box in python or in django, but it
should be pretty easy to write your own debug function. Python
supports excellent introspection. A very basic start would be
something like:

def debug(obj):
 ret = ""
 for attr in dir(obj):
  ret += "%s - %s" % (attr, getattr(obj, attr))
 ret += ""
 return ret

Which will return representation of every attribute and method in an
instance, and the string representation of the attribute. You can use
the isinstance method, or use the inspect built-in class, to only get
the atributes you require and customize it how you like. You can then
easily turn this in to a django tag so you can use it in templates or
whatever (see djangobook.com for writing custom tags and filters).

(caveat: i am new to python and django too)

resizing an image

[Lic. José M. Rodriguez Bacallao]

Hi folks, I know this question isn't from this group but I'll ask

width and height. I want to make my site browser resolution

a page showing a news entry, the news entry had an image (thumbnail) I
want to display. With a browser resolution of 1000x740, this page
display ok but with a resolution of 780x560, it don't. What can I do?
Right now, I think resize the image based on its size with javascript
but I don't know how to get the image (an element in general) size. I
tried the "element.style.width" but it return an string which I can't
convert to an integer (500px for example, I just want 500). Any
sugestions?

I'm kind of new to python and django, but I have some cakePHP

Deploying django framework with site

Folks,

Has anyone got any documentation on deploying the django framework as part of 
the site?  I'm considering using django for an app at work (on Oracle - so 
need SVN version?) and our release team will want a self contained site to 
deploy.  They're used to WAR files and like them.  It'll be a struggle to get 
them to install mod_python never mind getting a framework out of SVN!

Ta,

Tim.

Re: custom model field validation

[Jonas Pfeil]

You will need to use the newforms-admin branch to get the admin to use
a newforms field ;)

Btw: If you just want the regex functionality you can use the
RegexField of newforms like so:

def formfield(self, **kwargs):
defaults = {'regex':r"^[A-Za-z][1-9][1-7][0-9]$"}
defaults.update(kwargs)
return super(models.CharField,
self).formfield(form_class=forms.RegexField, **defaults)

Jonas

How to handle timezones correctly?

[David Larlet]

Hello,

I'm trying to make an application which deals with timezones thanks to  
pytz[1] and I can't figure out how to use hourly timezones instead of  
minutes based ones. For instance:

 >>> paris = pytz.timezone('Europe/Paris')
 >>> mydate = datetime(*time.strptime('2008-02-12', '%Y-%m-%d')[: 
6],**{'tzinfo':paris})
 >>> print mydate
2008-02-12 00:00:00+00:09

And if I try to use the normalize function, the date is changed :

 >>> print paris.normalize(mydate)
2008-02-12 00:51:00+01:00

I'm really surprised that some kind of "rounded" function for  
timezones exist. Or maybe I just didn't find it?
Any tips will be really appreciated.

Thanks,
David

You can ignore these messages from mod_python. You will see them every
time Apache starts up a new child process for handling requests. It is
just telling you that it is importing handler for mod_python for first
time for that process. If you were using mod_python 3.3.1, instead of
an old obsolete version of mod_python, you likely wouldn't even see
them, as mod_python shouldn't have really ever been making sys.path
modules reloading candidates as it causes too many problems. The
newest version of mod_python addresses the problems around that by
separating sys.path imports from its own.

ADMIN_MEDIA_PREFIX = '/media/admin'

Re: template & forloop help

[Marcin Mierzejewski]

Hi,

What is 'divs' in your example?
And what do you want to do it?

If you want to display a list "name1", "name2", "name3" you can do it
in this way:

view.py

divs = ('name1', 'name2', 'name3')

template.html
{% for div in divs %}
  {{ div }}
{% endfor %}

Regards,
Marcin

Does doing this do what you want?

{% for div in divs %}

{% endfor %}

or have I completely misunderstood what you meant?

Re: Using a drop down list as widget for filter in admin

[Julien]

Thanks James,

I did not find the documentation you're referring to, and by posting
here (twice) I was hoping to find a built-in option. But since there
doesn't exist one, I tried your suggestion and it was indeed pretty
easy to implement.

For those who are interested, here's my solution. Create a template
admin/filter.html and paste the following into it:

{% load i18n %}
{% blocktrans with title|escape as filter_title %} By
{{ filter_title }} {% endblocktrans %}


{% for choice in choices %}
{{ choice.display|
escape }}
{% endfor %}




The flaw for that solution is that it overrides the way *all* filters
are rendered in the admin. Don't know if there's a way to indicate
what filter or app this should only apply to.

Also, I'm never completely satisfied when overriding the admin
templates, because that makes you tightly dependent on the admin
behaviour, which may possibly change one day or another and make your
customized templates crash without warning.

Re: custom model field validation

[Pigletto]

> So If I create a newforms field then how do I tell the admin to use
> that when building the form in the admin?
If you need this in admin then possibly you have to define your own
newforms field
with validation. It may be called: myfields.MyField
Then you define descednant of CharField from django.db.models like:

class MyDBField(models.CharField):
def get_internal_type(self):
return "CharField

   def formfield(self, **kwargs):
defaults = {'form_class': myfields.MyField}
defaults.update(kwargs)
return super(MyDBField, self).formfield(**defaults)

and you use MyDBField instead of CharField in your models.py file.

I've never tried this with Admin, so I'm not sure if this will do what
you want, but
it is simple enough to check it.
