I have a complex page of data and want to sort various columns of the
db so... the way I am trying to do it is
with jquery but I don't know how I can get the variable returned by
the jquery function into my template
maybe I should be using custom template tage for this?
Here is a very stripped down version
In my html file
<script type="text/javascript">
function sort_col(col_name,seq_name)
{ $.postJSON("/jobs/sequence/sort_shots",
{seq:seq_name,col:col_name},
function (json)
{
{{shot_list}}=json['shot_list']; // this dosn't work but it
is what I would like to do
}
}
</script>
{% for f in shot_fields %}
<td onclick='sort_col("{{f}} {{a.name}}")'> {{f}}
<ol>
{% for s in shot_list %}
<li> {{s|lookup:f}} </li> <!-- where lookup is constructing a
string like a.name etc -->
{% endfor %}
</ol>
{% endfor %}
Here is the view function in views.py
# ajax request for sorting of database rows
def sort_shots(request):
result={'shot_list': []}
if request.method =="POST":
try:
seq=request.POST["seq"]
col=request.POST["col"]
except KeyError:
json=simplejson.dumps(result)
return HttpResponse(json,mimetype='application/json')
s=list(Shot.objects.filter(sequence__name=seq)).order_by(col)
result={'shot_list':s}
if len(s)==0:
json=simplejson.dumps(result)
else:
json=simplejson.dumps(result)
return HttpResponse(json,mimetype='application/json')
I don't want to just reload the page because it has quite a lot of
state that would be lost
Thanks for any help
