Re: A query question
Hi, Actually my question is not about the date range. i'm planning to use __lte and __gte filters. My problem is to solve the query (getting A objects using B objects) inexpensively.

Ok. Thank you so much. So, formset is a suitable way to achieve this. But, is it the most django-oriented way? Is there any alternative way?

Re: howto remove request.GET parameter
I realized that, there's nothing wrong with the removing code. The
problem is the return statement. when the dictionary req is empty the
def returns u"" and somehow old request.GET remains unchanged. So i
should return a specific value, when the dictionary req is null.

howto remove request.GET parameter
Hi,
I have a custom templatetag function like this:
@register.filter(name='rem_get_request')
def rem_get_request(getrequest,name):
req = getrequest.copy()
for get_item in name.split('&'):
if get_item in req and req[get_item]:
get_item = get_item.strip()
del req[get_item]
if req:
return u"?%s" % (req.urlencode())
return u""
"getrequest" parameter is request.GET
and "name" parameter is the parameters to be removed, splitted by '&'
(ampersand) (ie "min_price&max_price" )
The problem is:
If request.GET has more than 1 parameter (
?tag=mytag&min_price=1000&max_price=1500 ) i can remove one or more
parameters. But if request.GET contains only one parameter (
?tag=mytag ) then it doesnt work. the "if" statement works, but "del"
doesnt work. i cannot remove this last parameter. What am i doing
wrong?
Thanks for your information.

Re: nested template tags
thanks for your help...
template tag:
@register.filter(name='get_page')
def get_page(var, name):
return u"%s=%d" % (name,var)
template:
{% with i|get_page:'page' as xxx %}
i
{% endwith %}
yes, i was planning to use snippet at
http://djangosnippets.org/snippets/553/ for get parameters.

Re: change extension of uploaded image

cp_image = original.copy()
