how to show blank spaces at the start of string in django templates
Hi
I formated with python numbers like e.g.:
" 3457.50"
" 11450.25"
but my problem is to show them correctly one below the other
in a column by django templates
because the blank spaces are ignored.
I tried with the filter escape, however it does not work.
A solution would be to loop over the characters in string like:
{% for c in number_string %}{% if c == ' ' %} {% else %}{{ c }}{%
endif %}{% endfor %}
and so to replace blank space with but this is very cumbersome.
Can somebody tell me if we here have a simple and elegant solution?
Thanks in advance and best regards
Ogi

Re: DatabaseError: subquery has too many columns
Obviously the subquery has too many columns, namely
two: "error_test"."id", and "error_test"."name",
but you want that only "error_test"."id" is NOT in select
elements of the subquery.
I'm not even sure that your approch makes sense.

ModelAdmin - related foreign keys
Hi I'm new in Django and want to explain my issue: For instance I have model A with foreign key to B and model B with foreign key to C. I would like to have add form of C with one B (extra = 1) and within B four A (extra = 4) With the following example in admin.py I can only achieve this partly: for object C I have only extra B object without A objects related to B object. class AInline(admin.TabularInline): model = A extra = 4 class BAdmin(admin.ModelAdmin): inlines = [AInline] class BInline(admin.TabularInline): model = B extra = 1 class CAdmin(admin.ModelAdmin): inlines = [BInline] So can somebody explain me how to do dies, that I can have complete add-form inside the object C: with extra object B together with extra (sub)objects C ? Excuse me for bad english and lot of text. Thanks in advance for any hint. Best regards Ogi -- You received this message because you are subscribed to the Google Groups "Django users" group.

InlineModelAdmin related items on two levels
Hi all I read the very good tutorial on http://docs.djangoproject.com/en/dev/ref/contrib/admin/ and understood that the admin interface has the ability to edit models on the same page as a parent model and these are called inlines. For two related models is this easy: class A (models.Model): name =... class B(models.Model): a = models.ForeignKey(A) title = ... in admin.py: class B(admin.TabularInline): model = B class AAdmin(admin.ModelAdmin): inlines = [ B, ] and the result ist, that in add/change of A we can also add/change its child models B My Problem is that I however by B model have also child models: class C b = models.ForeignKey(B) name = ... My Question is : Is it possible than one can add/edit models of A on the one page together with child models B and C as child models of B. Any hint or idee would be very appreciated Ogi -- You received this message because you are subscribed to the Google Groups "Django users" group.

Hi Matt Thank you very much for Your reply and effort to manage this issue. It's pitty, that nested lists are not implemented in django.

Re: ajax select box
Hallo
You can use Dajax(ice) to solve your issue.
First Dajax and Dajaxice must be installed.
In your select box for countries add event 'onchange' i.e.:
onchange="Dajaxice.ajax.getCitiesByCountry('Dajax.process', {'name':this.name,
'value':this.value})">
According to this example you must have the file ajax.py and the function
getCitiesByCountry must be registered in settings.py like:
DAJAXICE_FUNCTIONS = (
'ajax.getCitiesByCountry',
)
Afterwards define the function getCitiesByCountry in ajax module
where you can generate options for cities using python and replace them
automatically in html.
If something is not clear google for Dajax, Dajaxice, dajax.json()
Greetings

ValueError: Need 2 values to unpack in for loop; got 3 (actually num_loopvars = 2 and len_item = 3)

ValueError: Need 2 values to unpack in for loop; got 3 (actually num_loopvars = 2 and len_item = 3)
Michal, Thanks very much for your reply.
I guessed, that is something like in your example.
And I find it in template.
So the conclusion is that there is no more allowed in django template
engine to use *for* loop with less elements to unpack,
and I think that is also consistent and more pythonic.
Best regards

Sounds like you are trying to loop over a list in your template,
something like this::
{% for a, b in mylist %}
...
{% endfor %}
The problem is that mylist contains triples, not pairs. It would help
a lot if you could show the actual template code, as well as the
context that you pass to the template.
Cheers,
Michal
