Look in the _meta inner class of your model - the fields property is
probably what you want. Something like:
dict((f.name, f) for f in mymodel._meta.fields)
should do the trick.

hardcoding login_url is not the way I prefer to go. I supposed there
is some solution to pass login_url dynamically, but it's impossible as
I can see.

List a model fields

[JF Simon]

Hello, i'm new with python (and french so my english may seem very
poor, sorry about that).
I would like to list a model's fields and return a dict, here is the
example :

I have a model class with :

meta_title : CharField(...)
meta_description : CharField(...)
body_header_title : CharField(...)
body_header_text : CharField(...)
foot : CharField(...)

This class represents context for a page. This class will have a
function get_context() who will return :

{
   meta :
   {
  title : 'value of meta_title' ,
  text : 'value of meta_text' ,
   } ,
   body :
   {
  header :
  {
 title : 'value of body_header_title ,
 text : 'value of body_header_text ,
  }
   } ,
   foot : 'value of foot'
}

So i would like to :

1. get the list of my class's fields attributes
2. parse their names to obtain the dict

Thanks a lot to the ones who read this message to the bottom !!
Long live the Django project !!!

In hindsight, I probably wasn't clear as to why I'm suggesting this:
there are a lot of places where Django would like to write to your
database (sessions, auth lookups, ...). You can configure around and
away from each of those in turn, but, if this were me, I'd save on brain
wear-and-tear by letting Django behave normally until and unless I
wanted to talk to this other read-only database and then I'd explicitly
point my database connection in that direction. I have no stronger
technical reason for my suggestion than that; it's primarily intuition
and gut-feeling, but you don't have to tell anybody that.

Malcolm

You'll probably want to set things up so that the "natural" database is
your Django-specific one and then accesses to the other database is done
via a custom manager.

There are a few blog posts around about accessing multiple databases in
ways that work reliably, until such time as Django ships with it by
default. I'll just point you to this one, since I had the link to hand:

Re: login problem

[vierda]

Hi Matias,

Thanks for your reply but I did'nt get your point. sorry I'm newbie
and still learning.
I modified my_view function in my views as your suggestion (if I
didn't wrong get your point) as per below:

def my_view(request):
   if request.method == "POST" :
  username = request.POST['username']
  password = request.POST['password']
  user =  authenticate(username=username, password=password)
  render_to_response ('login.html', {'username': username,
'password' : password})

  if user is not None:
 if user.is_active:
login(request,user)
return render_to_response('success.html',
{'username':username})
 else:
return HttpResponse('disabled account')
  else:
 return HttpResponse('invalid login')
   else:
  return HttpResponse ('home page')

above code run and shows home page text, I assume that the method is
not POST regarding the result.
What sholud I do to fix this and show my login page. somebody please
help me to understand this concept. Thank you

Re: Sort Table Headers after data has been rendered via a POST request

[SnappyDjangoUser]

I wanted to run this by the group one more time does anyone know
how to handle sorting results by table header URL after a POST
request?

I have used the SortHeaders class for GET requests and it works
great.  I am hoping to find a way to extend this for POST requests.

Thanks!

Accessing Multiple Databases.

[Tom Eastman]

Hey Guys,

I'm about to start developing a web front-end for a large database being 
developed by a colleague.  The web front-end is only going to be 
accessing a sub-set of the database, and mostly via 'views' that will be 
specific to the requirements of the web frontend.

I want to use Django, since I'm vaguely familiar with it (and it rocks). 
But what I want to do is have one database for all the django-specific 
stuff, so that I don't have to create any django-specific tables in the 
main database.

Can anyone point me in the direction of achieving this?  Will I still be 
able to take advantage of Django's database API or will I end up having 
to drop to raw SQL a lot more?

I'm just kind of testing the waters at the moment.  Anyone have any 
experience in similar situations?

Thanks!!

 Tom

If you look at the function signature for logout_then_login(), in
django/contrib/auth/views.py, you'll see that it accepts a login_url
parameter.

The parameters passed via the "url" template tag are parameters that are
captured by the regular expression for that URL pattern. Your pattern,
in this case, is "accounts/logout/", which has no variable pieces --
that is, the reg-ex has no capturing groups. That's a good thing, since
it's not really something the user is ever going to control -- there's
precisely one way to logout.

However, if you want to pass some extra information to the
logout_then_login function, look at the third argument in the url() call
-- the dictionary of extra parameters. You can set up the login_url
parameter there.

Malcolm

Seriously. :-(

The remainder of your message is almost 400 lines long. That's in
addition to me having to know about batchadmin, which I have no
knowledge of. I'm all for helping out on mailing lists, but there is a
limit to the charity!

So let's fall back to first principles: always construct the smallest
case possible that repeats the failure. This means start with a template
that includes nothing but the "extends" of the batchadmin template. If
that works, you can start adding in the other lines until things stop
working and then back up a step to work out the problem that arises. If
the single line template does not work, you have a one-line template
that you can start debugging. It is *much* simpler.

Good luck,
Malcolm

Re: Django newbie observation

I would be +1 for a link to Pinax project at the end of the tutorials.

Ayayalar:
pinax-0.5.0.tar.gz 
Once the download is complete, uncompress it and you should be able to cd
intoprojects/complete_project/ or projects/basic_project/ and run
./manage.py syncdband ./manage.py runserver to get running immediately.

This seems to be an enormously large assumption. How have you worked out
that mark_safe() is doing this? A quick glance at the relevant pieces of
source (mark_safe() and the SafeUnicode class) will show it doesn't care
one wit about a slash character.

> Langues

The shell output you show doesn't look at all like the final output you
show, so it's not from the same run. I'm cautious about comparing apples
to oranges here. Since you print "rendered_cb" in the above code
fragment, that would be the relevant output to be comparing. Does it
have a trailing slash?

In short, there's information missing here. mark_safe() isn't doing
anything special that would affect this, as far as I know. I think you
need to take a few steps back and compare the output at each stage.

Malcolm

Whilst I use similar vintage RHEL boxes with at least one client, I
don't use MySQL on them, so this hasn't been an issue for me.

However, there's a larger issue at play here and, if you've got support
for RHEL, you should consider bringing it up with Red Hat: the reason
Django does not allow 1.2.1 prior to p2 is that it has a very serious
threading bug that causes crashes. Django managed to hit that bug and
there are details in our Trac if you, or somebody looking at that,
wanted to spend time searching amongst older closed tickets. *Nothing*
should be using it unless the mysql-python package been specifically
patched to work around that. You should check to see if it has been
patched by the vendor (RH) to avoid that problem. In an unpatched state,
it's simply a broken package containing a showstopper bug.

If it has been patched you *might* be able to just remove the version
check in the mysql backend of Django and things might just work (run
Django's test suite to check). To maintain version compatibility, Red
Hat often don't change the reported version number when they do
backpatch a package, which isn't unreasonable, but it does mean
something doing version checking (which is the most practical solution
for the other 97%) is going to raise a false negative. It's been a while
since I dived into the internals, but, from memory, 1.2.1 was more or
less identical, internally, as far as the API went, to 1.2.1p2 and we
don't do anything beyond using the public API.

Aside from that, you're just in the "normal" situation here with
long-lifetime, stable systems. Software that is younger than the
packaging date of your system version sometimes depends on more recent
versions, which themselves depend on more recent versions, etc. Django
does a pretty good job of being flexible and accommodating with respect
to maintaining older support, and even we have to draw the line
somewhere (we spent 18 months, and a lot of care, phasing out support
for MySQL-python < 1.2.1p2, in order not to disrupt too many
situations). A lot of other releases aren't willing, or possibly able,
to be that gentle.

Finally, it's not clear what you meant when you wrote "other file
versioning problems". If you can get the wrapper to compile (it should
only need the mysql-client libraries to build against and anything back
to late MySQL 3.x works with mysql-python, again, from memory), then you
can install it locally somewhere and set your Python path to pick up
your local copy before the system one. It sounds like you're trying to
upgrade the system-installed rpm, which is usually not a great idea on a
system like that (not just because it usually invalidates support
contracts, but because it makes future maintenance harder). Local
installs are preferred.

Regards,
Malcolm

Yes, this was fixed post 1.0 release.  If you upgrade to 1.0.2 it may fix
your problem.

Re: PREPEND_WWW

[jmat]

I'm using 1.0

Is the patch post 1.0 ?  I was having a tough time figuring out if
that patch was post 1.0 or not on the ticket (I'm probably blind ;)

APPEND_SLASH is not modified (so it is default True)

I changed PREPEND_WWW to True but it did not seem to have any
effect...

I can try the patch if it is a post 1.0 ... haven't had time to go
chase into the django code to compare.

HTTPS and URL form field validation

[Nick]

Hello,

My Django 1.0 project is installed on two different servers (one is
development, the other staging, both running Red Hat Linux). The main
page has a form with a URL field, and I'm using the built in Django
field validation, which determines whether the URL is valid by seeing
if it's reachable. My problem involves HTTPS URLs. (Plain old HTTP
URLS work fine on both servers.)

On the development server, an HTTPS URL validates just fine. On the
staging server, with the same URL, Django returns an error, saying
"This URL appears to be a broken link."

Using other facilities on the staging server, such as wget, I am able
to reach the HTTPS URL.

At first we discovered that the staging server was running Python
2.5.2 that had been installed without SSL support. However,
reinstalling with SSL support did not fix the problem. I believe the
system administrator also rebuilt mod_python.

Any ideas on what could be going on?

Thanks.

Nick

logout_then_login - how to alter login_url

[redbaron]

quote from official docs about logout_then_login view: "login_url: The
URL of the login page to redirect to. This will default to
settings.LOGIN_URL if not supplied"
How to supply alternative login_url?

I add logout url to urls.py:
 url(r'^accounts/logout/
$','django.contrib.auth.views.logout_then_login',name='logout'),

Then I'd like to redirect user to my custom page after logout succeed,
how could I do that?
{% url logout login_url="/my/custom/path" %} doesn't do the job, I
catch error in reverse function.

Beginners questions on forms containing multiple related model types.

[Brian]

Hi,

I'm new to django and have been working hard to find "the right way"
or at least "a good way" to do things.  I'm running into a few
problems though that I can't get answers for.

The following post describes my situation very clearly.  It may be
long-winded but hopefully it's unambiguous.  I'm sure there'll be
nothing difficult to the experienced django user here, but some
answers could be helpful to me and other beginners.

In my django model I have the following classes: Person and
BankAccount.  There are other model types too, but these should
suffice to illustrate my problem.

Person:
  person_id
  first_name
  surname

BankAccount:
  bank_account_id
  person_id (ForeignKey)
  bank_code
  account_number

A Person may have ZERO or ONE BankAccounts.
I want to be able to create or edit the details for a Person
(including their associated BankAccount, should it exist) on the one
html form.  I've created some ModelForm types to help with this:

class PersonForm(ModelForm):
class Meta:
model = Person

class BankAccountForm(ModelForm):
class Meta:
model = BankAccount
exclude = ('person',) #Avoid the dropdown menu

I've been advised (on IRC #django) that "create new" should be handled
at one URL and "edit existing" at a separate URL.  I handle the URLs
at different view functions.  So in url.py:
url(r'person/add/$', 'person_add', 'person_add'),
url(r'person/(?P\d+)/$', 'person_edit',
name='person_edit'),

The "person_add" view function is easy to implement.  For request.GET
for I simply create a new PersonForm and a new BankAccountForm and
expose them to the template via the context.  The request.POST is easy
too - however I only save the BankAccount data if non-blank data was
supplied.

The "person_edit" view function raises some problems though:
1) I may be editing a Person that has no associated BankAccount.  So
basically I'm supplying a form with "edit existing" functionality for
the Person model and "create new" functionality for the BankAccount.
This doesn't cause a problem in itself, but it does break the paradigm
of separating "create new" and "edit existing" functionality - if such
a paradigm is indeed correct.

2) When a GET request to /person/5/ is received, I retrieve the
relevant Person from the db.  In a separate db query I then have to
try to get an associated BankAccount.  If I do:
BankAccount.objects.get(person=person_id)
and the BankAccount doesn't exist a DoesNotExist exception is
thrown... This really surprised me.  Thinking about it from a db query
perspective I would have expected an empty list.  I notice however if
I do:
BankAccount.objects.filter(person=person_id)
I receive an empty list when there is no match.  I presume this is by
design, I just wonder what the logic of that design is.  Any ideas?

3) When a POST request to /person/5/ is received the URL tells me I'm
editing Person "5", but I also need to know if I'm editing or creating
a BankAccount too.  I can obviously query the BankAccount table for a
record matching person_id=5, but again there is a db roundtrip
overhead here.  Alternatively, I think I could have included a hidden
bank_account_id field when I received the GET request for /person/5/
so that upon POST I would "know" the bank_account_id - with some
security concerns though.  What is best-practice in this situation?

4) You might notice that the relationship between Person and
BankAccount is modelled as a One-To-Many, however my business logic
requires One-To-(Zero or One).  I wondered if I could use the
models.OneToOneField for this, but the documentation seemed to imply
that django would expect exactly one record on BOTH sides of
relationship, so it may not be suitable for the One-To-Zero case.
Again, if anyone has advice on what I should actually do here, please
let me know.

Obviously this is a simple example and I could code a solution that
would work.  However, my real problem involves several similar
relationships on the one form.  The POST handling code could get very
hairy if I don't do it well.

If you got this far, thanks for taking the time to read this.

Re: PREPEND_WWW

[Craig Kimerer]

Which version of Django are you using?  Do you also have APPEND_SLASH set to
true?  There was a ticket about this a while back that was fixed (
http://code.djangoproject.com/ticket/9199).

Hope that helps.

ModelAdmin list_filter presets: usability best practice?

[Jeff Kowalczyk]

Does anyone have a best-practice suggestion for ModelAdmins which are
best used with a preset list_filter? Put another way, where are the
best usability customization points so the user sees a specific list
filter when entering that modeladmin, and when being redirected after
various actions, but also seldom runs into an annoyance where they
have to 'unfilter' repeadedly to see the change_list they want at this
one point in time.

For example, I have a model where the appropriate list_filter
settings  are ?assigned_to__id__exact=(user_id)__exact=1

Thanks for any suggestions.

Re: Postgres Full-text search -- is it possible?

[alex.gay...@gmail.com]

It can be done using extra as shown here:
http://barryp.org/blog/entries/postgresql-full-text-search-django/
there isn't a way built into django
to do it however, there are also a few external search projects to
create a nicer search api in django.  This one: 
http://code.google.com/p/djangosearch/
specifically was worked on as a part of the google summer of code and
perhaps you could speak with them about a pg backend if they don't
have one already.

Re: PREPEND_WWW

@jmat I have never tried Django's PREPEND_WWW, but it can easily be

are possibly better left to Apache.

Apache has a rewrite guide that has all the information you should
need. I found a good link a while ago with exactly what you are
looking for, but my search skills are crummy today. Search for "apache
force www", and you should find what you need.

Re: Generating a slug from an m2m field

[Delta20]

In case anyone else is looking for a solution to this, here's the work-
around I came up with:

In the ModelAdmin class for Ticket, override the save_model function
and force the m2m relations to be saved. For example:


class TicketAdmin(admin.ModelAdmin):
model = Ticket

def save_model(self, request, obj, form, change):
super(TicketAdmin, self).save_model(request, obj, form,
change)
form.save_m2m()
obj.update_ticket_slug()

The drawback is that save_m2m gets called twice (the second time is in
the change_view function), but this is a small price to pay to get the
desired functionality. If anyone knows a better approach, I would
appreciate hearing about it.

http://docs.djangoproject.com/en/dev/ref/forms/fields/#datefield

documents how to override the default valid date formats for input to a
DateField.

http://docs.djangoproject.com/en/dev/topics/forms/modelforms/#overriding-the-default-field-types

describes how to override the default fields created by a ModelForm.  So I
think you want to override the field in your ModelForm and specify a
different list of valid date input formats.

Re: Multiple apps extending admin/change_list.html

Thank you, I have made batchadmin find its media in my development
setup.

My change_list.html, which now extends batchadmin/change_list.html, is
not
selected for rendering/has no effect in the filesystem layout I would
expect to
work, and recursion error problems in next most likely layout.

The following layout results in a recursion error:

  $ tree /path/to/acme/acme/widgets/templates
  /path/to/acme/acme/widgets/templates
  |-- admin
  |   `-- widgets
  |   `-- widget
  |   `-- change_form.html
  |-- batchadmin
  |   `-- change_list.html
  `-- widgets
  |-- detail.html
  `-- index.html

Both layouts below have no effect on rendering the searchbar
customization, but
generate no recursion error:

  $ tree /path/to/acme/acme/widgets/templates
  /path/to/acme/acme/widgets/templates
  |-- admin
  |   `-- widgets
  |   `-- widget
  |   `-- change_form.html
  |-- batchadmin
  |   `-- widgets
  |   `-- widget
  |   `-- change_list.html
  `-- widgets
  |-- detail.html
  `-- index.html

  $ tree /path/to/acme/acme/widgets/templates
  /path/to/acme/acme/widgets/templates
  |-- admin
  |   `-- widgets
  |   `-- widget
  |   |-- change_form.html
  |   `-- change_list.html
  |-- batchadmin
  `-- widgets
  |-- detail.html
  `-- index.html

The last is the layout which works prior to the batchadmin and changes
to
extend batchadmin/change_list.html.


The following is the djang-batchadmin batchadmin/change_list template
extending
admin/change_list:

  $ cat /path/to/django-batchadmin/batchadmin/templates/batchadmin/
change_list.html

  {% extends "admin/change_list.html" %}

  {% load batch_list %}

  {% block extrahead %}{{ block.super }}{{ batchadmin_media }}{%
endblock %}

  {% block result_list %}
  
  {% if batchadmin_on_top or not cl.paginator.count %}{% actions %}
{% endif %}
  {{ block.super }}
  {% if batchadmin_on_bottom and cl.paginator.count %}{% actions %}
{% endif %}
  
  {% endblock %}


And per http://www.djangosnippets.org/snippets/1239/ and this thread,
the
widgets app custom change_list.html extends batchadmin/
change_list.html:

  $ cat /path/to/acme/acme/widgets/templates/admin/widgets/widget/
change_list.html

  {% extends "batchadmin/change_list.html" %}
  {% load adminmedia %}
  {% load i18n %}
  {% load admin_modify %}
  {% block extrahead %}{{ block.super }}
  
  
  {{ media }}

  
  jQuery.fn.counter = function() {
// setup initial counter display
$(this).each(function() {
  var max = $(this).attr('size');
  var val = $(this).attr('value');
  var cur = 0;
  if(val) // value="", or no value at all will cause an error
cur = val.length;
  var left = max-cur;
  $(this).after(""

  // Style as desired
  var c = $(this).next(".counter");
  c.css("margin-left","10px");

  c.css("border", "1px solid #ccc")
  if(left <= 10)

  // setup counter to change with keystrokes
  $(this).keyup(function(i) {

if(left <= 10)

  });
});
return this;
  }

  $(document).ready(function() {

The above template works correctly before the addition of batchadmin
to the
setup below (and the change to extends). I've included a lot of setup
detail
below, not sure which may be relevant to the problem at hand:

Thanks for any suggestions.

Django + mail server

[prem1er]

Hey everyone,
   I'm trying to create a registration page on my website using Django
forms.  I just realized that I needed to install a mail server in
order to send confirmation messages to my users through the forms.
What type of setup is everyone using for this?  i.e. Postfix + mutt.
Thanks in advance.

Not sure what you are asking. I look in /etc/group to see what groups
apache belongs to. On my system, apache belongs to a group called
apache. So I did something like:

# chgrp apache uploads
# chmod 775 uploads

Re: login problem

[Matias]

Hello,

You should check by which method was called your view.
something like

if request.method == "POST":
#now you can use request.POST
else:
#just show the template


Hope that helps,

Re: Model field order

[bfrederi]

Nevermind, I think I found my answer.

in the model._meta attribute, there is an attribute called fields
(model._meta.fields) that is a list of the fields in the model, in the
order in which you defined them.

Model field order

[bfrederi]

If I've defined a model like so:

class comment(models.Model):
name = models.CharField(max_length=25)
place = models.CharField(max_length=100, blank=True)
comment = models.TextField()

How do I get the order I defined the model fields in, once I have the
model object.

For instance:

model = models.get_model(app_label, model_name)

I now have the model object, and I want to be able to get the correct
order of the fields as I have defined them (name, place, and comment,
in that order). Is there a method in django to get that ordering?

Use Q objects and OR them together:

http://www.djangoproject.com/documentation/models/or_lookups/


Foo.objects.filter(
   Q(field1='baz') |
   Q(field1='bar') |
   Q(field2='spatula')
   )


They should be groupable as well, so you can use

   filter(
 (Q(field1='foo') & Q(field2='bar'))
 | Q(field1='baz')
 )

-tim

Hi all,

when combining Django ORM criteria you get

How do I get the "...WHERE...OR..." clauses?

Resorting to raw SQL?

Re: Django Forms Date Format

[Aldo]

Let me add, that my model contains this

mydate = models.DateTimeField().input_formats = ('%Y.%m.%d %H:%M:%S',)

But when i use the input_formats arg it allows my field to accept any
numeric data
eg: 2342342/42354235 is now accepted.

Django Forms Date Format

[Aldo]

I am using django forms. I have created a model/form with 2 fields,
name and date.

Prior to saving the form i check if the form is_valid?

if form.is_valid():
form.save()

My problem is it wants the date in the format - MM/DD/
Otherwise it will not see the form as valid - and not save.

How can i change this I want the date in the format DD/MM/

Please help

Problem with field validation in 1.02

[rtmie]

H i ,
I am trying to migrate a project from 0.95 to 1.02 and so have to
migrate all of my old model based validator stuff in the new forms
style( my first encounter with the new forms style).

I am having a problem with the following:

in my model I have a AppUser class, with username , password , email
etc and I have a requirement that the username be unique , regardless
of case. I have a valifdation funtion to check this and raise a
ValidationError,
however when I call it with a duplicate name via form.isValid() I get
a return value of False (i.e validation failed as expected) BUT the
form.errors list is empty. I am obviously doing something dumb, but
can't for the life of me figure it out.
Can anyone see if I am missing some step:

Model:

class AppUser(models.Model):
name = models.CharField(_('name'),
max_length=100,
db_column='name',
unique=True)
email = models.EmailField(_('email'),
 db_column='email',
 blank=True,
 max_length=320)
password = models.CharField(_('password'),
max_length=30,
db_column='password')


Form:
class AppUserForm(ModelForm):
class Meta:
model = AppUser

def clean_name(self):
name = self.cleaned_data["name"]
if self.instance.id:
cps = AppUser.objects.exclude(id__exact=self.instance.id)
else:
cps = AppUser.objects.all()
for index in range(0,len(cps)):
if upper(cps[index].name) == upper(name):
raise forms.ValidationError, "App user name must
be unique, regardless of \
case"
return name

View:

def createUser(request):
form = AppUserForm()
if request.method =='POST':
form.data = request.POST
if form.is_valid():
log.debug("saving valid user")
cp   = form.save(True)
else:
log.error( form.errors)
log.error("error list: %s" , str(form.errors))
log.error("failed  App User validation ")

log output
app2008-12-15 14:46:26,384 [ERROR] error list:<--
expected to see something here
app2008-12-15 14:46:26,384 [ERROR] failed  CP validation

If you are using a correctly installed 1.0.2 then make-messaages should
be showing something like:

$ make-messages
make-messages has been moved into django-admin.py
Please run "django-admin.py makemessages " instead.

If yours don't, maybe leftovers of aprevious installation
are still in /usr/sbin or similar?

Something you could do is to manually apply the bisection method
between your revision that worked (r7496) and 1.0.2 (r9503)
to try to find the commit that broke things for you. The functionality
was moved from make-messages to django-admin at revision 7844.

MarkSafe and widget rendering "/" disapeared

[coulix]

Hello Djangonauts,
I have a custom widget to create a kind of group list which ommits the
last "/" at the end of an input field.
Making html validation to fail.

The important code is here:

   rendered_cb = cb.render(name, option_value)
print rendered_cb
output.append(u'%s %s' % (
option_label,
rendered_cb,
option_label)
)
...
   return mark_safe(u'\n'.join(output))

The shell output gives me






Thats all good

But then HTML output after mark_safe takes this input "/" away
Langues
 Anglais

 Espagnol
 Japonais


If i do the safe as a filter it still remove the last /, what is the
solution ?

(for now not validating html is not the end of the world)

Re: problem with make-messages.py russian language

[Dafidov]

Hi Karen.
Thank You for quick answer.
Unfortunately after check and changing commend still not work :(
Before I was using django 0.9.6 changeset 7496 and all worked fine.
It's strange because when I'm using old command
make-messages.py -l pl  I have no errors...

I was checking coding and in all languages files - they are saved with
utf-8 encoding so it's not a problem too.
I' working on:
Distributor ID: Ubuntu
Description:Ubuntu 8.04.1
Release:8.04
Codename:   hardy

and have xgettext (GNU gettext-tools) 0.17

I'm using as translation editor poedit in version 1.3.9.

By saying that make-massages suspend - i have on my mind that in
console it looks like it is working - but never ends... can wait hours
and nothing :/

Do You have any other ideas why make-massages.py and django-admin.py
makemessages -l ru doesn't work correct on Russian language ?

Best regards
Dafidov

I'd recommend using the Browser class of python mechanize:
http://wwwsearch.sourceforge.net/mechanize/

Should make most operations a lot easier, plus you can check for links
etc, then just "click" on them which is rather handy.

I'm using it to monitor a few sites (not, unfortunately, written in
django), and it is rather nice being able to just click round the place
and get data out again when needed. Mechanize + BeautifulSoup is
a very nice combination indeed.

Thanks,

Re: SOAPpy and pyxml installation/usage

[Steve]

OK. I'm having second thoughts on suds. It seems to work great some
times, but not so great on others. I have the following code, where
vid is the wsdl of the video.
Many of them fail. I got these wsdl's from http://www.xmethods.net and
presumably they're good.

def check(vid):
   try:
  client = Client(vid)
  print "succeeded: " + vid
   except:
  print "failed: " + vid

for x in wsdl:
   check(x)

It fails quite a bit, just to load the wsdl file. Here's the results:
succeeded: http://ws2.fraudlabs.com/mailboxvalidator.asmx?wsdl
succeeded: http://www.imcomponents.com/imsoap/?wsdl
succeeded: 
http://coeservice.en.kku.ac.th:8080/TemperatureConvertor/TemperatureConvertorService?WSDL

If anyone has any thoughts, I'm all ears. I'm going to try to post
this on the suds page, see if they can't fix it.

I got this piece of js which seems to fit my need [0]. However, I'm
still wondering how to integrate it into my Django code.

I have a radio button in my model which is called "type". That button
should be the one which calls the js. Any tips on how to get this?

Thank you very much, Fabio.
