This actually sounds like the error I was getting when lighttpd was
attempting to execute my site as plain CGI and not FCGI, been a while
since I fixed it so I dont remember the exact error

Flup:Unhandled Exception

[madhav]

Hi all,
I am facing the dreaded "Unhandled Exception" raised by Flup. The sad
part is its raised at the webserver(lighttpd+flup) level and not at
the application level(Django). So no 500 email is raised about where
the problem is. Our entire team struggled hard to cleanup the
codebase, incase of any ambigous imports and someones of that sort,
just to be eliminate the chances of raising errors due to the
ambiguous imports. And we cleaned up many things in the code. Still
the same exception. To be frank I am really frustrated with Flup's
error handling. It doesn't tell you anything, worst of all, it shows
the same "Unhandled Exception" to the Users. How do I get pass this. I
checked the lighttpd logs, all I see is "Interface Error/Connection
already closed." Its only occuring when my applicaiton is running in
FCGI mode. so the problem is with how flup is actually dealing with my
code(application). How do I get pass this. I checked for alternatives
for flup, but Django depends on flup explicitly(which is one more
restriction, and puzzled me)(Reference:django_src/django/core/servers/
fastcgi.py line:100 / 131)

How do I debug(atleast) this scenario and solve the problem? Please
help me out. The application is down since 3 days. :(

filter() returns another QuerySet, that is it returns multiple objects,
get() returns a single object and raises an exception if either more than 1
object are returned, or none are returned.

 I think I need to find a way to start a HTTP server at the beginning of
 the test and keep it around till all test are done. And have a way to tell
 the server what to return on the request.

 You should be able to save the thread on the Test object during setup()

Working with URL Fields in django test.

Hello,

If I am using a URLField in form and it set to verify the URL, if I write
tests for the code and in the post I push a url like *http:google.com *it
will fail if the computer is off-line. Is there a good fix for this?

Re: Testing Django and HTTP Request

Right the problem is if I reload the server on ever test, there is not
enough time for the thread to kill the server. So when the next setUp comes
around the port is still in use.
I think I need to find a way to start a HTTP server at the beginning of the
test and keep it around till all test are done. And have a way to tell the
server what to return on the request.

Testing Django and HTTP Request

[Vitaly Babiy]

Hello everyone,

I am working on a project that will need to make a request out to the web
and pull down some data, For testing purpose I was wonder what would be the
best way to test this. I don't want to make the actual request during the
test, because for one if I am off-line all those tests will fail.

I have tried to implement a HTTPServer in python. The problem I am having is
once I have it thread, If I put it in the setUp method  and tearDown I get
port in use exception. Due to the nature of the thread it is not guaranteed
to be killed in time.

Re: problem with simple shopping cart

[lnysrogh]

Thank you so much. That helped a lot. Such a simple mistake.

I've got some other questions now. My "add to cart" code:

def add(request, product_id):
added = (Product.objects.get(id=product_id), 1) # '1' is quantity
request.session.set_test_cookie()
if request.session.test_cookie_worked():
request.session.delete_test_cookie()
if 'cart' in request.session:
if added in request.session['cart']:
request.session['cart'][1] += 1
else:
request.session['cart'].append(added)
else:
request.session['cart'] = []
request.session['cart'].append(added)
return HttpResponseRedirect('/cart/')
else:
return HttpResponse('You need to enable cookies')

The code worked until I tried to check if the product is already
stored in the cart and to add 1 to the quantity instead of storing it
again. I'm getting this error: "can only concatenate tuple (not "int")
to tuple". What am I doing wrong?

Also, Andrew, I tried storing only the product id in the session
instead of the product object, and calling it in the show cart page.
Removing the "quantity" part of my code to simplify since it's not
working, I tried this:

Using the code above, I stored just the product_id in added, not the
Product.objects.get(id).

def cart(request):
if 'cart' in request.session:
cart = request.session['cart']
for item in cart:
cart = Product.objects.get(id=item)
return render_to_response('cart.html', {'cart': cart})
else:
return HttpResponse('Nenhum produto')

I get this: "int() argument must be a string or a number, not
'tuple'".

It seems there is one concept I'm not getting right, since I'm getting
similar error messages for totally different problems.

Any help?

Problem with set_language generic view

[yav]

Hello,

I have a problem with the generic view set_language. I used it but it
doesn't change the language. I have read the doc but I didn't find
what is the problem. I have read the doc but I didn't find what is the
problem. I have setup an empty project in order test it with a very
simple example. Here is my config: http://dpaste.com/hold/118420/.

I'm working with the latest svn version. I tested the application with
Safari and Firefox and with Apache and the development server, but it
doesn't work anyway.

Does anyone have a working example? Because all the examples I have
used don't work. Here is the test project in a zip file:
http://dl.getdropbox.com/u/576053/multi.zip

Alberto

Re: Extending the User model

[Patricio Palma]

Yeah you're right
I can't believe that
I mix the admin settings in the class, for a short explanation.

my code:
---
models.py
from django.contrib.auth.models import User
class MyUser(User):
chilean_rut  = CLRutField(_('RUT'),primary_key=True)
some_field = models.CharField(max_length=50)

admin.py
class MyUserAdmin(admin.ModelAdmin):

list_display = ('chilean_rut', 'email','some_field')

admin.site.register(MyUser,MyUserAdmin)

-

And my list_display is EMPTY ( on the  http://127.0.0.1:8000/admin/myapp/myuser/

Best practice question: subclassing external app components

[zinckiwi]

Hi folks,

I'm just starting to play with django-registration and I want to
subclass the RegistrationForm for a couple of cosmetic tweaks
(capitalising the labels on the fields -- there may be a simpler way
to do this, but indulge me for the purposes of this question). I
understand that subclassing RegistrationForm and reassigning the label
strings is the way to do this -- no problem.

My question is where to *put* that subclass. I can think of a few
places:

- the project itself
- an "overrides" app dedicated to holding overrides for external apps
- a "registration_overrides" app dedicated to holding overrides for
just that one external app

Perhaps there are other ways. Of these, I'm favouring #2. While #3 has
the virtue of being more portable, it seems like a lot of (logical)
overhead to perform a simple modification to another app.

So I guess I'd like to hear if there's an accepted way to do this, or
failing that, what anyone has found to work well (or what to avoid).

Thanks all,
Scott

The second part actually isn't necessary; if you pass the first part
of the module path (e.g., some_module.__path__[0]) as the keyword
argument "path" to get_svn_revision(), it'll happily go hunt that down
and calculate the SVN revision of that path rather than Django.

Two steps:

1) Look at django.utils.version.get_svn_revision(). This method tells
you Django's SVN revision. Make a copy of this method and modify it to
point at your own code, telling you the version of your clients SVN
checkout.

2) Write a template context processor to insert that version number
into the context.

When you install the template context processor, the SVN revision will
become available to every template.

Wondering what the best approach would be to add my projects revision

Ditto what Russ said: I've not seen this.  Your earlier note, which I had in
my list of things to go back to and try to answer when I had more time if no
one else responded, mentions you are using Google App Engine...does that
apply to what you are talking about here?  I've not done a lot with GAE, but
some,and I haven't seen this behavior there either -- I get regular Django
debug pages under GAE, though actually I'm only 100% sure of that when
running in the development environment, I don't know that I've tested it on
a deployed project.  So specifics of a small test case that demonstrates the
problem you are seeing would help track this down -- it doesn't seem to be
behavior people are seeing generally.

I can't say I've seen this before. The Django 500 handler hasn't
changed for some time, and I've always found it to be pretty robust.

If you're having problems, we'd like to address them, but it's
difficult to do so in an abstract sense - we really need a concrete
example that fails. The easiest way to do this is to take the example
that is broken, and start cutting things out until you are left with
the minimal possible example that still exhibits the problem. Once you
have a minimal project (probably something like a single view that
crashes under certain input conditions), send that to us along with
your environment (OS, Python and Django version) and we can try to
replicate the problem and work what is going on.

Yours,
Russ Magee %-)

??? indeed.  What doc are you reading that suggests having  something like
"admin = meta.Admin(..." under class Meta of your model definition?  I've
never seen anything like it but I've only been around since 0.96 or so and
others seem to recognize it as very old syntax from earlier releases.  If
you were running r9820 I'd expect you to get a NameError on that line since
there's nothing named meta to support that call.

The current way to set list_display, if you are running 1.0 or more recent,
is documented here:

http://docs.djangoproject.com/en/dev/ref/contrib/admin/#modeladmin-options

The admin defs are all now included in ModelAdmin classes, there is no more
admin definition tied into the model class definition itself.  But if you
were running a relatively recent Django, I'd expect you'd be seeing errors
with the code you are showing us, so I am rather confused by your report of
no errors, just not the results you were expecting.

Adding fields to model objects that don't correspond to database state

[Jack Orenstein]

I have a model object that looks something like this:

   class Foo(models.Model)
   foo_id = models.IntegerField(primary_key = True)
   xyz = models.CharField(max_length = 20)

In my application, I'd like to add a list of Bar objects. It's like a  
foreign key, except that Bar objects don't exist in my databases. So  
I want a Foo.bars field.

- If I just create the field:

   class Foo(models.Model)
   foo_id = models.IntegerField(primary_key = True)
   xyz = models.CharField(max_length = 20)
   bars = []

Then the list belongs to the class, not instances.

- If I try creating the field lazily, e.g.

   class Foo(models.Model)
   foo_id = models.IntegerField(primary_key = True)
   xyz = models.CharField(max_length = 20)

   def attach_bar(self, bar):
   if self.bars is None:
   self.bars = []
   self.bars.append(bar)

Then calling attach_bar from the application results in an  
AttributeError, 'Foo' object has no attribute 'bars'.

- Specifying Foo.__init__ to initialize bars doesn't work, because it  
interferes with creation of Foo objects from database queries.

I played around with subclassing, e.g. class FooBase 
(models.Model) ... class Foo(FooBase) but couldn't get that to work.

How can I add a field to the Foo class that doesn't come from the  
database?

Extending the User model

[Patricio Palma]

Greetings

I've a model
class MyUser(auth.User):
location = meta.CharField(maxlength=100, blank=True)

class META:
replaces_module = 'auth.users'
admin = meta.Admin(
list_display = ('username', 'email',
'first_name','last_name', 'lacation')
)


looks fine, but, after add a new myUser (successfully) my user list
it's empty

just like a list_display = ('')

what is wrong?

Thanks

How to detect inactivity session time out?

[ydjango]

I am setting inactivity session time out using -
 a)  request.session.set_expiry(900) and
b)  SESSION_COOKIE_AGE = 900

I believe both work exactly the same way. Please correct me if they
have any different behavior.

How do I detect this time out in my app and give user a page that they
have been timed out due to inactivity.
I am using django standard authentication using autheticate(), login()
and logout()

It's because Python tries to look inside the directories/modules in
PYTHONPATH. So it was actually looking for:

/var/www/django/legend/legend

which obviously doesn't exist.

Glad it's working though.

This code looks exceptionally old, admin = meta.Admin() has been gone for
several years, what version of django are you workign with?

Re: Postgresql v MySQL

[AmanKow]

I started with mysql and moved to postgres.  My main reasons:

1) If you ever need to dumpdata/loaddata, you may find that postgres
(correctly) defers checking of fk constraints until after the a
transaction is complete.  MySQL checks the constraints as each record
is added, even inside of a transaction.  This can break a dump/load
cycle, requiring a manual reordering of records in the fixture.  And
can make circular references impossible to deal with at all.

2) Postgres transactions can wrap table altering, creation and
deletion.  MySQL cannot.  This is essential if you want sane, safe
migrations.

I found Postgres  a bit more difficult to get going, but not
appreciably so.  After the small amount of additional pain, it has
been rock solid.  pgadmin works quite well for administration tasks.

So, unless my hand is forced in some way, I find postgres a better
choice than mysql.

Exception in Django's Exception Handling

[Devel63]

Django is raising an exception while trying to process an exception,
resulting in no stack traces ... for many different types of errors.

It has the problem in debug.py, at this line under
technical_500_response:
return HttpResponseServerError(t.render(c), mimetype='text/html')

I have DEBUG=True, and TEMPLATE_DEBUG = DEBUG.  The situation arises
for almost any error (undefined var, missing func arg, call to
undefined member func, etc.), but in some cases it does actually
generate a stack trace!

Any ideas?

pre-populating multiplechoicefields with session data

[Bobby Roberts]

Hi group.  Please look at this view:

# this form runs the search mechanism
def DoSearchForm (request):
if request.method =='POST':
form=SearchForm (request.POST)
if form.is_valid():
try:
myuid=request.user.id * 1
except:
myuid=0
#form submitted passes validation so submit to database as
a valid search term record
mydata = SearchAttempt (
Terms = CleanMe(request.POST.get('Terms','')),
suid = myuid
)
mydata.save()   #save to sarch_attempt table
# save items to session variables
request.session["Terms"]=request.POST.get('Terms','')
request.session["Iforand"]=request.POST.get('Iforand','')
request.session["Programelement"]=request.POST.get
('Programelement','')
request.session["Disaster"]=request.POST.get
('Disaster','')
request.session["Submissionmethod"]=request.POST.get
('Submissionmethod','')

return HttpResponseRedirect('/search/results/')
else:
return render_to_response('submit-search.html', {'form':
form}, context_instance=RequestContext(request))
else:# load form for first time
if 'Terms' in request.session:
form = SearchForm(initial={'Terms':request.session
['Terms'],'Iforand':request.session
['Iforand'],'Programelement':request.session
['Programelement'],'Disaster':request.session
['Disaster'],'Submissionmethod':request.session['Submissionmethod']})
else:
form = SearchForm(initial={'Iforand':'exact'})
return render_to_response('submit-search.html', {'form':
form}, context_instance=RequestContext(request))


This view is working perfectly except for one thing.  If someone
completes the form, it saves the form options to a session and inserts
the term they searched for into the database.  If they close their
browser and come back to the search form, I want their previous
choices to populate the form again.  Terms and Iforand populate as
they should.  Programelement, Disaster, and Submissionmethod are all
multiplechoicefield textbox lists and none of the previously selected
options are selected.  Can you see what i'm doing wrong?

Yes you need to have 'django.contrib.admindocs'  and have the urls wired
up(you should just need to uncomment it from the default urls.py).

admin "Documentation" link not visible

  Django's admin interface includes a complete reference of all
template tags and filters available
  for a given site. To see it, go to your admin interface and click
the "Documentation" link in the

But I don't have that link - is there some configuration necessary to

Just a correction here -- MySQL actually has the GIS types built-in,
whereas with Postgres you have to install the PostGIS extension.
However, the PostGIS types and functions are feature-complete and
compliant with the relevant GIS standards, whereas the built-in MySQL
implementation is half-baked and non-compliant (e.g., no spatial
indexes on InnoDB tables, MBR-only functions, no distance
calculations).

I was once a MySQL user, but quite frankly I've become quite alarmed
at MySQL's attitude towards data integrity -- I just don't totally
trust it anymore.  With two botched releases in a row containing
critical bugs (5.0 and 5.1), my impression hasn't improved.  I'm a
developer who cares about his and his client's data first.

There's also pgAdmin III, a GUI interface available for PostgreSQL,
and installed by default with the windows installers.

Regardless, I second the opinion to develop for both so one can make
their own judgment to which best suits their needs.

I actually got it to work by changing the PYTHONPATH from '/var/www/

due to my version of python or what.  But thank you for the help.

Postgres has full text support from 8.3 onwards, however django doesn't have
support for using it from within the ORM yet, see

Thanks. Between posting and your response I found out that MySQL

But Django seems

DHTML Grid

[Manoj]

Hello,

I need to dynamically add rows to table similar to what has been done
in http://dhtmlgrid.sourceforge.net/debug/demo.htm. This code was
released in 2003 i wonder do we have code that i can use in my
project.

I am not sure about the robustness of the code.

Thanks in advance.
Regards,
Manoj

You've got the same problem with duplicating 'legend' in your
DJANGO_SETTINGS_MODULE spec and PythonPath spec as the poster in this
thread:

http://groups.google.com/group/django-users/msg/e8411403c00de3f6

had duplicating 'mysite', and you have the same options for fixing it as I
described there.

I am testing Django on my production server so that when development
is finished, I know I can actually use what I have done. There is no
point in doing the development if I am unable to use the work.

This sort of thing can certainly be done, the django-photologue application
(http://code.google.com/p/django-photologue/), for example, has a
GalleryUpload model that lets you upload a zip file of images and the zip
file is automatically expanded to its constituent images when you save a new
GalleryUpload object in the admin.  I have not looked at how exactly it is
implemented, but looking at its code might point you in the right direction.

If you want more specific help with the code you've got, giving people a
clue what "it doesn't work" looks like would probably help.  I like puzzles,
but I don't much like ones that are missing pieces, and leaving out the
details of what is going wrong: what you do, what you expect the outcome to
be, and what the outcome is instead, including any error messages and
tracebacks -- is leaving out a few too many pieces for me to have any
interest in looking at your puzzle.

Upload ZIP-File into Database

[Robert]

Dear Community,

I have a ZIP-File which contains five .lst-Files. I want to fill with
these five files a mysql-database. Is there a possibility to handle
this via the admin interface? I tried the following but it doesn't
work:

from django import forms
from django.contrib import admin
from cStringIO import StringIO
import zipfile
from dateiverwaltung.models import UploadZipFile

class UploadZipFileForm(forms.ModelForm):
class Meta:
model = UploadZipFile

zip_file = forms.Field(widget=forms.FileInput())
#zip_file = UploadZipFile.zip_file

def clean_zipfile(zip_file):
msg = 'File must be a valid ZIP-archive'
if zip_file.content_type != 'application/zip':
raise forms.ValidationError( msg )
else:
zipname = zip_file.name
zippfad = zip_file.chunks
zip = zipfile.ZipFile(fname)
assert False
try:
zip = zipfile.ZipFile(StringIO(zip_file.content))
except:
raise forms.ValidationError( "Not able to unpack the
archive" )
bad_file = zip.testzip()
zip.close()
del zip
if bad_file:
raise forms.ValidationError( msg )
return zip_file # Return the clean zip_file

zip_file.clean = clean_zipfile

class UploadZipFileAdmin(admin.ModelAdmin):
form = UploadZipFileForm
list_diplay = ('zip_file', 'uploadtime')

def save_model(self, request, obj, form, change):
pass

admin.site.register(UploadZipFile, UploadZipFileAdmin)

Since the forms seem pretty much disjoint, and are completely  
separated on the page itself (it's not like you're mixin two django  
Forms in a single HTML ), why don't you just send each form to  
its own view for validation?

Re: Two forms one page

You realize that you could simply do something like this to check if
'somefield' is a key in request.POST?

   if 'somefield' in request.POST:
  ...

I didn't realize you could do that, it works now.
I am using request.POST.__contains__(key), I think this is what you

Could you please post:
- The directory your Django project is in;
- The directory Django itself is in; and
- The output from the following command:
python -c "import sys; print sys.path"

?

And if you're really using mod_python already with Apache, also post
your vhost file.

To be honest though, if you're using Django for development you'd
really be better off with the built-in runserver for the moment.

Two forms one page

[tsop]

Hello,
I have a small problem here, I want to display two forms on the same
page and I need both forms to validate/submit independently from one
another. The problem I am having is that there is no way to tell which
form is being submitted to, if they are both left empty and one submit
is clicked both raise validation errors.

Since the view and template is quite a bit of code I've pasted them to
a pastebin:

The view:
http://dpaste.com/118076/

The template:
http://dpaste.com/118077/


King Regards,
Titus
