Re: serializes a object error with serializers.serialize("xml",query,ensure_ascii=False)

I figure it out what's going on. I define ForeignKey in the models.

data =  serializers.serialize('xml', query,
ensure_ascii=False,fields=('content'))

serializes a object error with serializers.serialize("xml",query,ensure_ascii=False)

[ERic ZoU]

Hi,
When I try to serializes a object with the function below:

def left(request):
 query = Talk.objects.all()
 data = serializers.serialize("xml",query,ensure_ascii=False)
 return HttpResponse(data)

Always give me this kind of error message.But if I just simply return
HttpResponse(query), it all works.
-
DoesNotExist at /Talk/Left
Talk matching query does not exist.

Any Idea ?

Re: Really, realy strange MySQLdb problem, cycling through error messages.

[Rishabh Manocha]

There was a permission denied error 'cause if your webserver was
running under some user other than root (as it should be), it won't be
able to write to the root's home directory (as it shouldn't).

Assuming you are using Apache with mod_python, here is something you
could put in your httpd.conf:

SetEnv PYTHON_EGG_CACHE /tmp/python-eggs

Include this with the rest of your settings for the django app.

Best,

Re: Testing login required views

[Julien]

In another thread [1] James Bennett suggested to use a middleware to
require login for all views. That is indeed a very simple and elegant
way. Here's the code I ended up with:

from django.contrib.auth.decorators import login_required
from django.conf import settings

public_paths = ['/accounts/register/',
'/accounts/login/',
'/accounts/logout/',]

class AuthRequiredMiddleware(object):
def process_view(self, request, view_func, view_args,
view_kwargs):
if request.path.startswith(settings.MEDIA_URL) or request.path
in public_paths:
return None
else:
return login_required(view_func)(request, *view_args,
**view_kwargs)


Cheers!

We have 'true' SSO working with multiple Django applications at my
workplace, using CAS and an authentication backend based on
django-cas; IIRC we're planning to release an updated version to the
world at large. I'll check on this tomorrow.

We actually don't share database across the applications, so logging
into each instance (which might just consist of a bunch of redirects
if the user's already authenticated to the CAS server) creates a new
user object in the Django instance's local database. This even works
for multiple instances on the same domain (or not), as long as you
remember to use a different SESSION_COOKIE_NAME for each instance.

Conceptually, the SSO is done one layer deeper than Django. Individual
Django instances are themselves clients to the SSO service (CAS, in
this case).

Of course, I don't think this has anything to do with what the OP was
needing, but your post reminded me of this anyway.

But is it true SSO?

Just sharing the same user database doesn't necessarily help in that
you still have to log in to each application.

Although using HTTP Basic Authentication is easy to manage off a
shared authentication handler, it is generally harder when it is a
form/cookie based login system.

In mod_wsgi you would probably see 'client connection closed'. At
worst if something bad happened which more precise reason couldn't be
determined then 'failed to write data'. The latter might occur though
where an output filter in Apache implemented by some other Apache
module screwed up.

See:

  http://code.google.com/p/modwsgi/issues/detail?id=29

for an example error message and some discussion about whether or not
there should be an ability to suppress the error message.

Well, they can share a database and auth against a single users table
(we do this all the time), or you can have an external authentication
source and write an auth backend which knows how to talk to it and
authenticate against it, then use it on all the sites which need it.
I've seen people doing LDAP and various other corporate-love-fest auth
systems that way.

This is where I am ignorant of what can be done with Django. But then
rereading OP question I may have been reading too much in it. My
initial impression was that he was talking about distinct Django
instances. I forgot that Django has a concept of applications within a
specific Django instance. Because of mod_wsgi I always tend to think
of the more complicated cases that need to be handled. :-(

Let me ask my own question then. If one is running multiple Django
instances, does Django provide anything that would help with single
sign on (SSO) across all the distinct Django application instances?

There are obviously various challenges with this because of need for
single session database, plus any requirements for configuring
settings.py as to naming of the cookie, setting of cookie path and any
magic session keys that might need to be shared.

I remember something about Paste (Pylons?) having some support in it
for working with a SSO module which is available for Apache. Can't
remember the name of the Apache module right now, not sure if it is
mod_auth_form or not. This is handling most stuff outside of Apache,
except perhaps for the user authentication through a special script.

It's actually not that hard, even if you want to require auth only for
specific areas. A middleware like this might do the trick (with a
little tweaking):

from django.contrib.auth.decorators import login_required

class AuthRequiredMiddleware(object):
def process_view(self, request, view_func, view_args, view_kwargs):
if ... (fill in test here to see if it's a URL or view you

Re: Admin : Select category -> show subcategory

Ok Martyn, understood.
Mainly that piece of code represents many functions, one inside the
other, since you need to reuse one, than you could declare this inner
function that you are aiming at, outside the event and call it on the
event(s) (in your case onchange and document ready).
That way you will have to write this function only once.
What do you think?

Testing login required views

[Julien]

Hi,

I have a site where pretty much all views (except for register, login
and logout) require the user to log in. Now that the number of views
has grown I'd like to test that I didn't forget to protect them with
the login_required decorator.

I'm looking for an automated way to do that. Is that achievable, and
if so, how?

I've started looking into unit testing but I'm struggling a bit and
I'm not sure if that could do the trick. What I'd like to do is test
all possible urls from the URLConf and spot those that are not
redirected to the login page.

Any hint?

Thank you,

Julien

Re: load external xml and css with varibles?

I'm afraid I don't quite understand all of your question, but I can

As far as I know, CSS files can't have variables or constants defined
within them. To have different colour backgrounds, my first approach
would be simply to have different CSS files, e.g. base_red.css,
base_green.css, etc. This is an approach I am currently using in a
development I am doing, however, the drawback is obviously going to be
the ongoing maintenance of two or more CSS files which need to be
identical apart from one or two lines defining the colour. Probably
not a tremendous problem if it is ONLY the background colour which
needs to change... The applicable CSS file to be used can be defined
using the template system: in my base.html (which defines to overall
structure of all subordinate pages) I have the following line:

(in the . block): 

The variable {{ style }} can be defined in the URL, or maybe in the
GET data (eg www..com/?style=red), or anywhere you like.

This worked fine for me, because I am using it to define more than
just the background colour, but also to radically change the layout of
the page, such as fonts, borders, graphics, element positioning etc.

However the next stage might be, to have more than one stylesheet for
the page... I think this would work fine for just background colour
changes, for example:

Style sheet red.css:
body {background-color: #FF;}

Style sheet green.css:
body {background-color: #00FF00;}

Style sheet base.css:
All the other stuff!

base.html:

 
 


I haven't tried this yet, but I think it would work.

The third thought to occur to me was to use JavaScript (or something)
to directly modify the DOM model, however at this stage the learning
curve seem too scary to me, however it might actually be the best way
in the end, if the variations in styles become too complex.

Creating a form class based on fields stored in the database

[MrJogo]

I want to create a web interface where users can create a form (ie,
define the number of fields and what types of fields they are and the
name to display), which will be stored in the Django database, and
then displayed elsewhere on the site as an actual form. Any ideas how
best to do this, specifically how to turn data stored in a database
(probably as a charfield) into a form object? Any examples of this
already being done? Is there a Python method to turn strings (ie,
"forms.CharField()") into the objects they represent?

Depends on what sort of authentication you want to use.

If you want to use HTTP Basic authentication, then put everything

This indicates that the browser (or proxy) closed the connection
before all response content had been sent. Use live headers extension
for Firefox to capture the response headers and make sure the Content-
Length is actually correct for the amount of data sent. Some browsers
are more tolerant of incorrect content lengths on responses than
others. If the browser is being more strict it may close connection
immediately it sees content length read, but if you were wrongly
sending more data than that, result would be truncated and would get
this error on server side if running with 'info' for LogLevel. Note
that by default LogLevel is 'warn' and you wouldn't normally see this
message.

You could also use any of the various network traffic analysers to
also monitor what is being sent in response and thus work out at what
point the connection is being cut off and whether it is consistently
at same point.

The part of the url following (and including) the question mark is not
actually part of the url, if you see what I mean, but is actually the
data passed as GET data. And Django provides an easy way to get at
this. Example,

The address required is : "http://www.mysite.com/?
query=dosomething=1" will be intercepted and passed to the
views.py module, with a line in urls.py similar to : "(r'^
$',views.intropage)" (this calls intropage for the main site name,
"mysite.com") - at this point you are NOT trying to match with the ?
query=xxx=1 part, just with the url part www.mysite.com/

Then, in views.py, you define a subroutine, which might look something
like this:

def intropage:
query="some default value"
page="1"#(default to page 1)
if "query" in request.GET:
query=request.GET("query")
if "page" in request.GET("page")
page=request.GET("page")
#go get the data or whatever you need to do...
return render_to_response("firstpage.html",locals())#or whatever you
need...

hope this helps

Simon.

Django Json server testing, new to Django

[puff]

I'm rather new to Django and working on a site that will need to do
the usual Django things by way of serving DB backed dynamic pages.  It
addition it needs to serve JSON and make JSON requests.

For the moment, I'm just experimenting with some very simple tests
using Django's development web server.

I'm able to get JSON responses ok from 'http://localhost:8000/json'
but when I try to access a JSON URI for json_get Django hangs.  If
instead of   'http://localhost:8000/json' I access 'http://
www.google.com' things work.  I assume that there is an issue with
Django's development server that limits it to serving a single view at
a time.  Can anyone verify this?

Thanks for any clues.

Puff


< code >

import urllib
from django.http import HttpResponse
from django.utils import simplejson

# test json view
mtj = 'application/json'
mtt = 'text/plain'
mt = mtt

def json(request):
data = {'first': 'richard', 'last': 'bell'}
json = simplejson.dumps(data)
return HttpResponse(json, mimetype=mt)

def json_day(request, day):
data = {'first': 'richard', 'last': 'bell', 'day': day}
json = simplejson.dumps(data)
return HttpResponse(json, mimetype=mt)

def json_get(request):
print 'in json_get'
url = 'http://localhost:8000/json'
#url = 'http://www.google.com'
f = urllib.urlopen(url)
print 'got f'
print f
doc = f.read()
print 'got doc %s' % doc
return HttpResponse('Inside json_get with <<%s>>' % doc)

Re: Really, realy strange MySQLdb problem, cycling through error messages.

For future reference: fixed, it stabilized to the 3rd error message. I
added this to __init.py__ in the application's directory:

os.environ['PYTHON_EGG_CACHE'] = '/tmp'

Apparently there was some permission error on '/root/.python-eggs'

Creating search forms

[Matt]

I'm trying to figure out the best way to create basic search forms in
Django. Currently I'm using newforms and have a simple view that takes
the parameters, calls the appropriate filters and returns the results.


# newform
class ProjectSearchForm(forms.Form):
p_type = forms.ModelChoiceField(queryset =
ProjectType.objects.all(), required=False)
p_stage = forms.ModelChoiceField(queryset =
ProjectStage.objects.all(), required=False)
p_status = forms.ModelChoiceField(queryset =
ProjectStatus.objects.all(), required=False)


# view
def project_search(request):
p_type = request.GET.get('p_type', None)
p_stage = request.GET.get('p_stage', None)
p_status = request.GET.get('p_status', None)

data = {'p_type':p_type,
'p_stage':p_stage,
'p_status':p_status,
}
search_form = ProjectSearchForm(data)
if search_form.is_valid():
results = Project.objects.all.(),order('name')
if search_form.data['p_type']:
results =
results.filter(p_type=search_form.data['p_type'])
if search_form.data['p_stage']:
results =
results.filter(p_type=search_form.data['p_stage'])
if search_form.data['p_status']:
results =
results.filter(p_type=search_form.data['p_status'])
else
results = []
context = Context()
context.update({'search_form': search_form})
context.update({'results': results})
return render_to_response('projects/projects_list.html',
RequestContext(request, context))



However, it seems like I should be able to abstract things so that I
the actual field only show up in the form declaration.
  - I don't have to set each field to send into the form
  - I don't have to set a filter for each field


Something more like this:

#view
def project_search(request):
#create search form with current request variables or using intial
values for form?
search_form = ProjectSearch(request.GET)
if search_form.is_valid():
#QuerySet filter created by search form?
results = Project.objects.filter(search_form.filter)
else:
results = []
context = Context()
context.update({'search_form': search_form})
context.update({'results': results})
return render_to_response('projects/projects_list.html',
RequestContext(request, context))


I've been looking around a bit at generic views, but it didn't seem to
be quite what I am looking for. Is this type of generic search form
currently possible?

Any help would be appreciated. Thanks!

Matt

You don't *know* that is what the exception is, you assume that.  This 
is one reason it is bad to catch all exceptions.  You don't know what 
you are getting.

The loop, as written, will continue.  There is something else going on.

I would add print statements to determine what is in fact happening.

  try:
  b = OrderEmail(name=row[0], email=row[1], been_sent="0")
  b.save()
  print "saved", row

Re: Incrementing by 4 instead of 1?

Yeah, I actually did start with a model method, but added the temp
variable because I was worried I was missing some magic.

Anyhow, I just got it sorted out -- my browser's broken.  It's
submitting every POST as a POST followed by three GETs, and ever GET
as four GETs.  I'll be filing a bug against it.

Re: Incrementing by 4 instead of 1?

[Sean]

Something which may cause this is if your template includes any empty
image, javascript, or css references (i.e. ).

If you have anything like this in your template, your web browser will
fetch the page multiple times (it will think that current page is the
file you are trying to reference) causing your value to increment
several steps each time you visit the page.

You don't need temp varible.  and there is a short cut for your 
try/except 
http://www.djangoproject.com/documentation/shortcuts/#get-object-or-404 
This would do

def adopt_bunny(request, id):
   bunny = get_object_or_404(Bunny, pk=id)
   bunny.adoption_count += 1
   bunny.save()

Don't know why it would inc by 3 or 4.  Assuming you are running dev 
server...  I'd add a print statement in there

   print "bunny %s: %s" % (bunny.id, bunny.adoption_count)

just to see when/if this code is being called multiple times and the 
value of adoption_count when it is.  Maybe add print to Bunny's save 
method to see where else it is getting modified/saved.

Also I'd probably make a method in the BunnyModel instead of doing this 
in the view.  Maybe overkill for this case (but today's overkill is 
tomorrow's maintenance saving feature)

Bunny(Model):
   ...
   def adopt(self):
   self.adoption_count += 1
   self.save()

Then from your view call it

def adopt_bunny(request, id):
   bunny = get_object_or_404(Bunny, pk=id)
   bunny.adopt()
   return single_bunny(request, id, True)

Get the 'named links' from the request path

[deepc]

Does anyone know how to get the 'named links' from the request path
from with a view? For example, I'd like to get 'blah' from the
following URL: test.com/somepage/?someget=xyz#blah

I know about the methods request.path or request.get_full_path()...
but neither these return the 'named' part of the URL.

The reason this is important is because I'm using AJAX to modify the
page. A well known practice is to use 'named links' to change the
location of the document without having the browser reload the page.
So pages like test.com/my_document#page=1 and test.com/
my_document#page=2 do not need a full reload and each can be book
marked by the user.

Really, realy strange MySQLdb problem, cycling through error messages.

[Rodrigo Culagovski]

I'm setting up a django site on the production server and ran into a
MySQLdb problem. The server is cycling through a series of error
messages:

1) ImproperlyConfigured: Error loading MySQLdb module: No module named
MySQLdb

2) ImproperlyConfigured: Error loading MySQLdb module: bad local file
header in /usr/local/lib/python2.5/site-packages/MySQL_python-1.2.2-
py2.5-linux-i686.egg

3) ExtractionError: Can't extract file(s) to egg cache

The following error occurred while trying to extract file(s) to the
Python egg
cache:

  [Errno 13] Permission denied: '/root/.python-eggs'

The Python egg cache directory is currently set to:

  /root/.python-eggs

Perhaps your account does not have write access to this directory?
You can
change the cache directory by setting the PYTHON_EGG_CACHE environment
variable to point to an accessible directory.

4) the "It worked! Congratulations on your first Django-powered page."

This cycling happens just by refreshing the same page, making NO
changes to the server at all. It's always in the same order. The first
2 text errors change after just 1 refresh, the last one takes 3 or 4
and the "It worked" message takes a bit longer before going back to
error 1.
I svn'ed the application into the appropriate directory, with urls.py,
etc., so I shouldn't be getting the "It worked" message at all.
I recently installed MySQLdb, and it installed setuptools
automatically.

Re: downloadable django site example anywhere?

[Adam Fast]

Kenneth,

http://code.djangoproject.com/svn/djangoproject.com/

Is the URL you want for subversion.  The "browser" url uses the
web-based browser to look at it file by file.

Unfortunately though you won't find a lot of newforms / modelforms
stuff there I'm afraid (or lost-theories unless it's been updated
since I last looked).  I'm not positive if there is any public code
out there that does that.

I will share some simple code from one of my projects that is using it
and working.  This is all in a single app.  The
text_message_subscribe() view is called in my URLs.


models.py-

class TeamNotification(models.Model):
team = models.ForeignKey(Team)
notification_type = models.ForeignKey(TeamNotificationType,
verbose_name='Type of Notification')
destination_carrier = models.ForeignKey(NotificationCarrier,
verbose_name='Your Cellular Carrier', null=True, blank=True)
destination = models.CharField('Your (Ten-Digit) Wireless Number
or Email Address (No dashes/spaces please)', max_length=255)
welcome_sent = models.BooleanField(default=False)
reminder_sent = models.BooleanField(default=False)
active = models.BooleanField(default=True)

forms.py-

from django import newforms as forms
from project.team.models import TeamNotification

class TeamNotificationForm(forms.ModelForm):
class Meta:
model = TeamNotification
fields = ('team', 'notification_type', 'destination_carrier',
'destination')


views.py--
def text_message_subscribe(request, object_id=None):
if request.method == 'POST':
form = TeamNotificationForm(request.POST)
if form.is_valid:
new_subscription = form.save()
return HttpResponseRedirect('/subscribed/')
else:
form = TeamNotificationForm()
return render_to_response('team/team_detail_subscribe.html',
{'form': form.as_p(), })

Re: Try Except Statement not working properly.

[Greg]

Since we know what the exception is.  The email address already exist
in the db (I have unique=True for the email field).  I thought that
having 'except: pass' would solve that problem.  However, do I need to
catch a certain exception in order for my loop to continue.  Because
as of now when the exception happens my loop stops.

Thanks

I need some help on this questions for helping me build my site

[sebey]

OK so as you may see I have a lot of questions in helping build my
django project so here they are

   1. with models do just create the fields that you need?
   2. how can I import rss feeds(i am running a podcast network) from
other sites/soures?(models,views,admin etc)
   3. I want to make an email newsletter and I want to know how to
make an email list in django?
 1. I want this to work that django grabs the latest entry in
the feed and grabs the  tags etc.
 2. also maybe have django make extra boxs for typing text
in
   4. also I need to make a calender I am planning to use google
calender cause of ical feeds and things like that can I print these
off (an other app maybe)?

thank you

Incrementing by 4 instead of 1?

[ringemup]

Hi folks,

I feel like I must be doing something stupid.  I've got the following
view:

def adopt_bunny(request, id):
try:
bunny = Bunny.objects.get(pk=int(id))
except:
raise Http404
adoptions = bunny.adoption_count
adoptions = adoptions + 1
bunny.adoption_count = adoptions
bunny.save()
return single_bunny(request, id, True)

Every time I make this request (after the first time for that
particular bunny), it increments by 3 or 4 instead of by 1.
single_bunny() just calls the object_detail() generic view with some
extra context.

How can I track down what's going on?  Or am I doing something
completely braindead?

Thanks!

Re: Using ModelForm...not populating my choices

[Adam Gomaa]

So your model is like:

class Folder(models.Model):
user = models.ForeignKey(User)
# yadda yadda

And you want to give the user a form to sort an object into one of
their own folders. So what you do is make a form like this:

class ObjectSortForm(forms.Form):
folder = models.ModelChoiceField(Folder.objects.all())

But, if your view, you don't actually want Folder.objects.all() - you
want user.folder_set.all(). So, you have to set the
form.fields['folder'].queryset attribute like this in your view:

def my_view(request):
if request.method=="POST":
# yadda yadda form handling...
else:
form = ObjectSortForm()
form.fields['folder'].queryset = request.user.folder_set.all()

# etc etc...
return render_to_response("my_template.html", dict(form=form))

Unfortunately, the docs are somewhat incomplete - they only explain
how to set the initial queryset. I've been meaning to write up some
documentation explaining the .queryset attribute, so thanks for
spurring some action :)

get_decoded in django shell results in SuspiciousOperation exception

[msoulier]

I'm trying to inspect the session data in the db.

>>> from django.contrib.sessions.models import Session
>>> q = Session.objects.all()
>>> for s in q:
...print s.get_decoded()
...
Traceback (most recent call last):
  File "", line 2, in ?

And yet...

>>> pickle.loads(base64.decodestring(s.session_data))
{'orderby': 'clientid', 'spp': u'20'}

There's my data. Doesn't look corrupt.

I have no issues in the UI, just when using the Django shell.

Re: ModelForm and MultiValueField

[fivaldi]

Hi Omat,

Does your HistoricDateField implement the compress(self, data_list)
method and _not_ the clean(self, value) method? See the implementation
comments in django.newforms.fields.MultiValueField. The compress
method should also return the compressed value of the historic date
(i.e. one value representing the historic date based on the multivalue
input)  and that value should be available in the cleaned_data.

ModelForm and MultiValueField

[omat]

Hi all,

I wish to have an extra date field in my ModelForm. When I do it as
follows, it works fine:

class NoteForm(forms.ModelForm):
date = DateField(required=False)

def clean_date(self):
# do the validation ...
return self.cleaned_data

class Meta:
model = Note


But I wish to use a MultiValueField instead of a DateField. So I
defined a custom date field derived from MultiValueField and used it
as follows:

class NoteForm(forms.ModelForm):
date = HistoricDateField()
...

The form is displayed as I expect, but now clean_date() method of the
form is not called and cleaned_data does not have the data for 'date'.

Am I missing something or is it a bug?


Thanks,
omat

That is not the reason, and if you really wanted to you could mix your 
app code and templates, by setting TEMPLATE_DIRS.

None of your django code, templates, settings etc needs to be accessible 
via browser nor should it be.

There's a difference between authenticating the user, which you've
done, and making the user object available as a variable to the
template, which I'm guessing you haven't done. You probably want to
read this:

Memcached problem

[[EMAIL PROTECTED]]

I'm trying to use memcache for caching, but when I turn it on, the
site proxy errors out. Looking in my error log, I'm seeing tons of
errors like:
Invalid URI in request get views.decorators.cache.cache_header.grm./
some/url/

suggestions?

user.is_authenticated is always false using default login

[Andrew English]

My view function uses the login required decorator:

@login_required(redirect_field_name='next')
def index(request):
   lists = List.objects.filter(user=request.user)
   return render_to_response('base.html', {'lists': lists})

This directs them to the login page:
LOGIN_URL = '/todone/list/login/'
LOGIN_REDIRECT_URL = '/todone/list/'

Which is correctly handled by the django auth default:
(r'^todone/list/login/$', 'django.contrib.auth.views.login'),

I am using the default template from the authentication instructions:

{% extends "base.html" %}

{% block content %}

{% if form.has_errors %}
Your username and password didn't match. Please try again.
{% endif %}



Username:{{ form.username
}}
Password:{{ form.password
}}






{% endblock %}

When the user logins in with correct credentials, they are redirected to the
expected page.  However in the template, user.is_authenticated is false and
user.username is empty.  But in the views.py, lists =
List.objects.filter(user=request.user) will return the expected results.
Even though the user is not authenticated, the request.user object has the
expected values.

Do I need to explicitly call authenticate and login in my own view to
populate the user data?  From what I read, it seems that the
django.contrib.auth.views.login does that automatically.

Thanks.

perlbal and django

[[EMAIL PROTECTED]]

here is my configuration
dyndns for round robin mode to two perlbal instances
two web server (lighttpd+fastcgi)
mysql-proxy
master-slave db configuration

the two perlbal are running on port 80, if I access my webapp through
the perlbal instance I got an "An unhandled exception was thrown by
the application"

if I access the lighttpd server directly (same machine as perlbal, but
different port), everything works fine

it seems that perlbal is not so transparent for the backend webserver
as it should

any experience with perlbal+lighttpd+fastcgi ???

Values from a ForeignKey object?

[mbdtsmh]

Hi all,

I assume there a way of accessing associated values from a ForeignKey
object in the fieldset.html template that comes with the newforms-
admin branch? I cannot for the life of me figure it out - HELP!

example:


  {% if fieldset.name %}{{ fieldset.name }}{% endif %}
  {% if fieldset.description %}{{ fieldset.description }}{% endif %}
  {% for line in fieldset %}
  {% for field in line %}
  {% ifequal field.field.name "designset" %}
  {{ field.field.form.initial.designset }}   
  {% else %}
  {% if field.is_checkbox %}
  {{ field.field }}{{ field.label_tag }}
  {% else %}
  {{ field.label_tag }}{{ field.field }}
  {% endif %}
  {% endifequal %}
  {% endfor %}
  
  {% endfor %}


In the above example I can print out the designset id
{{ field.field.form.initial.designset }} but cannot figure out how to
get at any of the values associated with this foreignkey table
(DesignSet table contains priority, status & project fields)

Can anyone put me out of my misery?

Regards,

Martin

Re: django newbie with an install problem - bad interpreter

[lorax]

FYI - (sorry about all the posts)

I edited the django-admin.py file and changed the first line where it
calls for env.

Original: /usr/bin/env
Edited: /bin/env

Now it works just fine. Thank you both!

downloadable django site example anywhere?

[Kenneth McDonald]

Is there a downloadable example of a Django site that illustrates the  
various things one needs to do to get the various aspects of a Django  
site working? In my case, I still don't have ModelForms working, and a  
complete, simple example would be better than all the descriptive  
prose that could be written about this.

Thanks,

Re: django newbie with an install problem - bad interpreter

[lorax]

That worked!

So adding "python" to the front of the command seems to be the trick.
Perhaps I should add a symlink to point to where Python lives?

re: patching django-admin

You could change the first line of django-admin.py from:

#!/usr/bin/env python

to

#!/bin/env python

Or, as Marco says you could preface the script name with 'python' and avoid
the whole issue.  The first line is just trying to get the shell to find the
appropriate python command to run in order to execute the script, if you run
python directly the first line is ignored (since it's a python comment).

re: breaking python

I wasn't saying you would break anything, I was saying the hosting provider
has caused things to break by putting env in a non-standard place.  Lots of
python scripts use that first line, and apparently none of them will work on
your hosting provider's setup because they've placed env in a non-standard
location.

Re: moving from MySQL to PostgreSQL on a "live" site ..

[oliver]

Thanks for all the advice! I think django could probably do with a
little tool like this when dumping or importing data.

Is the boolean field the only odd one out? or is there any thing else
that needs chanaging? Date fields? datetime?

Thanks again!

You can try without use env:

This is my first foray into Python so other than Django, I'm not sure

Hmm.  So env is in some non-standard place?  What does "which env" show?

You could patch your django-admin.py to point to where your host has put
env.  It's a bit odd for it not to be in /usr/bin, though -- this is going
to break plenty of python scripts that assume /usr/bin/env will be there.

django-admin.py is trying to run /usr/bin/env to launch python.  It sounds
like your host does not have /usr/bin/env?  What happens if you try the
command:

/usr/bin/env --help

from a command prompt?

Apache (and dev server) throws "connection reset" when accessing pages via IE 6

[Rishabh Manocha]

Hey Guys,

I have just deployed my code to my test server (from my laptop) and
setup apache/mod_python to serve the pages. Everything works just fine
when I work with Firefox, but whenever I access my pages using IE 6, I
keep getting the following errors in the apache error logs:

[Tue May 20 17:59:43 2008] [notice] mod_python: (Re)importing module
'django.core.handlers.modpython'
[Tue May 20 17:59:45 2008] [notice] mod_python: (Re)importing module

[Tue May 20 17:59:45 2008] [info] [client 146.208.137.89] (32)Broken
pipe: core_output_filter: writing data to the network

This results in my forms being thrown off the tracks and I end up
getting weird form results (going by the data being saved to the DB).

I am using apache 2.0 and mod_python 3.2:
httpd-2.2.3-6.el5
mod_python-3.2.8-3.1

My apache configuration is:

SetHandler python-program
PythonHandler django.core.handlers.modpython
SetEnv DJANGO_SETTINGS_MODULE MyProject.settings
SetEnv PYTHON_EGG_CACHE /tmp/python-eggs
PythonDebug On
PythonPath "['/opt/proj'] + sys.path"



I get a similar error using the dev server:

Exception happened during processing of request from ('127.0.0.1', 2144)
Traceback (most recent call last):
  File "C:\Python25\lib\SocketServer.py", line 222, in handle_request

  File "C:\Python25\lib\socket.py", line 346, in readline
data = self._sock.recv(self._rbufsize)
error: (10054, 'Connection reset by peer')

I read [1] where this guy had a similar problem but fixed it by
changing his proxy settings to make it such that going to localhost
does not take a route via the proxy. Trying the same thing did not
help in my case.

I was hoping someone else would have run into this problem and could
suggest a solution.

Many thanks,

Rishabh

Also see this ticket:

don't think it's been decided what to do about fixing this, though.

Help me build my site with answers to my questions from models to newsletters everybody view this at least once

[sebey]

OK so as you may see I have a lot of questions in helping build my
django project so here they are

   1. with models do just create the fields that you need?
   2. how can I import rss feeds(i am running a podcast network) from
other sites/soures?(models,views,admin etc)
   3. I want to make an email newsletter and I want to know how to
make an email list in django?
 1. I want this to work that django grabs the latest entry in
the feed and grabs the  tags etc.
 2. also maybe have django make extra boxs for typing text
in
   4. also I need to make a calender I am planning to use google
calender cause of ical feeds and things like that can I print these
off (an other app maybe)?


thank you

Re: Django Admin Site - How to view data in table, when insert/update/delete are removed for a user/group on a specified table

Admin's use of permissions is described here:

http://www.djangoproject.com/documentation/authentication/#permissions

You can disable insert/delete by giving a user/group only change permission,
but I don't see any way to allow a user to see table data without also being
able to update it.

django newbie with an install problem - bad interpreter

[lorax]

I've just got the keys to Django 0.96.2 on a semi-dedicated server at
WestHost. Largely spurred on by the receipt of the first of 4 Django
books. I fetched a copy of the download using wget and untarred the
file right from the command line on the server. I then attempted to
add django-admin.py to the server path and restarted the server. Then
I tried to execute the command django-admin.py startproject mysite.
That gave me an error:

-sh: /usr/local/Django-0.96.2/django/bin/django-admin.py: /usr/bin/
env: bad interpreter: No such file or directory

I thought my symlink might be bad so I tried executing the command
using the full path to django-admin.py which gave me the same message.
Since the files never touched a Windows machine could I still have a
hidden character in there? If so, how do I get rid of it? Or what else
might be the issue.

TIA Gregg

It sounds like you are trying to build psycopg2 from source instead of just
installing a pre-built binary.  Why not just install this:

http://packages.ubuntu.com/hardy/python/python-psycopg2

?

So i did

libpq is the C client library for PostgreSQL so no, its dev package wouldn't
help here.  I believe the error message was telling you to install the
python-dev package (or the dev package for mx.DateTime, but I don't know
what that's called), so as to get the headers needed to build Python
extensions like psycopg2.  So, if you really want to build psycopg2 instead
of just installing a pre-built binary, try again after installing
python-dev.  But using the prebuilt binary is generally easier.

The date() method of the datetime object is what you probably want.

Django Admin Site - How to view data in table, when insert/update/delete are removed for a user/group on a specified table

[Lalit Kapoor]

In the Django Admin Site is there anyway to enable a user/group to
view the data in a table, when insert/update/delete have been disabled
for the user/group? If so, how would I go about doing this? Thanks.


Sincerely,
Lalit Kapoor

Generally you can ignore it, it usually indicates that the user
pressed reload on a page or navigated off it before the browser could
send through the whole request.

BTW, it is good idea to mention what hosting mechanism you are using
when you get errors like this. I know this is generated by mod_python,
but the majority wouldn't.

Problem with Querydict

Hello,

I am sending JSON to the serverbackend.
When I print reuqest.POST I get .
Thats exactly what I was expecting.

But now I want to access the 'elems'. When I do request.POST['elems']
I get'1'.
But I was expecting getting 2, 1.

Thanks for your help.

problems with python setup.py build

[Wim]

Hello,

This is my first attempt to install Django on Ubuntu 8.04 with
PostgreSQL. It's all quite new for me. I'm pretty new to Ubuntu, I
have some programming experiences with Python and I'm totally new to
Django. I have used databases (Informix, DB2) for a long time, but not
PostgreSQL.

I have installed Django and PostgreSQL without problems But i keep
having trouble installing psycopg2.
error: psycopg requires a datetime module:
error: mx.DateTime module not found
error: python datetime module not found
error: Note that psycopg needs the module headers and not just the
module
error: itself. If you installed Python or mx.DateTime from a binary
package
error: you probably need to install its companion -dev or -devel
package.

So i did

sudo apt-get install libpq-dev

But that didn't help.

I looked for any DateTime files, i found /proc/7882/cwd/psycopg/
adapter_mxdatetime.h (right one ??)
I wrote this in psycopg2-2.0.7/setup.cfg
# If the build system does not find the mx.DateTime headers, try
# uncommenting the following line and setting its value to the right
path.
mx_include_dir=/proc/7882/cwd/psycopg/

The install stopped complaining about the mx.DateTime, but gave me
some new ones, about 120 lines of (mostly) errors and warnings.

TreeMenus / Extension - selected item

[martyn]

Hi,

I'm trying TreeMenus : http://code.google.com/p/django-treemenus/
It's a realy good job. Thanks to its author.

There is just a little bemol, I don't find the documentation really
excplicit, especially concerning the "Class Extension".


In the doc :

First, define your extension class (or create it if you don't already
have one)
like the following::
class MenuItemExtension(models.Model):
menu_item = models.ForeignKey(MenuItem, unique=True,
editable=False)
selected_patterns = models.TextField(blank=True)


Where to put his code ?
Create a new app in my project ?
Add this new app to my INSTALLED_APPS setting ?
Is this new app can be called "treemenus" ? (no)
The admin views has to be changed ?


This point is not very well documented, it's a shame.
Examples in the package should be great.
Why not integrate selected_patterns in the app ? I think it's a need
for every website.

Thank you.

Re: Admin : Select category -> show subcategory

[martyn]

In fact, at the creation, you select a category, the the
subcategories
are shown. It's OK

/*-/*-/*-/*-/*-/*-/*-/*-/*-/*-/*-/*-/*-/*-/*-
===Create_Object===

Category
[--select_category--]

SubCategory
[--select_subcategory--]

/*-/*-/*-/*-/*-/*-/*-/*-/*-/*-/*-/*-/*-/*-/*-

But, at the modification / edition of an object, I have to set the
right category and the right subcategory.

/*-/*-/*-/*-/*-/*-/*-/*-/*-/*-/*-/*-/*-/*-/*-
===Edit_Object===

Category
[--shoes--]

SubCategory
[--pretty_shoes--]

/*-/*-/*-/*-/*-/*-/*-/*-/*-/*-/*-/*-/*-/*-/*-

All I want is not to right the same javascript code twice
(on_selectlist_change == on_document_ready)
I don't know the better way to do this in django FW.
The only thing I did is to right the same code twice... It's not the
DRY philosophy of Django.

If you're on linux, there's sed and awk, or you could go ridiculously
old school and build something out of cut, paste, tr, grep, sort, uniq
etc., or you could write a little python filter to do it all for you:

import sys

for line in sys.stdin:
# change the line somehow
print line

or you could write something in perl, or you could...

I have a filter that makes django's json-dumps more human-readable, by
adding a newline after every occurence of "}},". Running such a filter
first would make for short and snappy lines for the rewriting filter:

python manage.py dumpdata | prettifyjson | fixbooleans > postgres_safe.json

Re: moving from MySQL to PostgreSQL on a "live" site ..

Hi,

I take it doing via JSON you still need to convert the Boolean fields?

would you know of any kind of scrip that would do it? as my editor
doenst cope to well with 7mb of xml files :(.
I guess its not to hard to write if needed.

I do a syncdb than run loaddata, I didnt empty the tables, will do
that thou, makes sence (I thought loaddata overwrite the "tables").

thanks for the info!

postgresql 8.3 and ILIKE

[Gacha]

I upgraded Postgresql to 8.3 version and got an error in admin:

ProgrammingError: operator does not exist: smallint ~~* unknown
LINE 1: ...js_id" = '6538'  AND "assort_apstlaiks"."a_diena" ILIKE
'2'
 ^
HINT:  No operator matches the given name and argument type(s).
You might need to add explicit type casts.

The field "a_diena" is an integer and from 8.3 version as changelog
says "Non-character data types are no longer automatically cast to
TEXT", so this sounds like bug.

Umm,  if it doesn't match a url.py re, I don't see how.  Is this an
issue when running under Apache?
I'm currently just using the dev server while learning.

My past experience says test each layer.  But, I suppose I could
probably just test the urls.py, view.py and templates with unit tests
using. the Client object.  This would indirectly test the business
objects and model objects get tested.

Re: business logic and good practices

[bcurtu]

Hi,

The reason you must place your templates out from your app code is
because if you don't do that, anyone could access to the code via
browser. Just writing the path of your files, and they have the code.
It could be a security issue.

About your managers.py file, it's OK to decouple logic from view and
model. But be careful with the name conventions. A Manager is an
interface to access to DDBB: 
http://www.djangoproject.com/documentation/model-api/#managers

Finally, not sure about unit testing...

Greets,

I could be wrong, but the way I have understood things is that initial
PIL people put stuff at global module level. After a while they
possibly realised their evil ways and pushed things into a PIL
package. To maintain compatibility with older way they did things they
add a PIL.pth file containing 'PIL'.

In other words both:

  import Image

and:

  from PIL import Image

work.

I personally would suggest that any code which doesn't import it out
of PIL package should be changed as it is propagating bad practice.

Thus, if Django is saying just:

  import Image

then it probably should be changed.

Anyway, my 2 cents worth.

Graham
