Good morning,
I'm new to django, and in need for a little pointers:
I've a bunch of Choicefields that I want to update ( similar to
Country-city-street, type of behavior ).
How would I go about updating those fileds, without reloading the
page?
Javascript? Ajax? or django have a way to update only given form/
objects:
Here's the code I've so far, it works by reloading the entire page.
** just to make sense: *pipeline is the frontend DataBase handler.
# THE VIEW ####################
def index( request ):
if request.method == 'POST': # If the form has been submitted...
assetMgr = AssetManager( request.POST )
assetMgr.update( request.POST )
else:
assetMgr = AssetManager()
return render_to_response('inventory/templateSeq.html', {'asset':
assetMgr,
'post':
request.POST})
# THE FORM ###################
class AssetManager( forms.Form ):
## Get productions
listProd = [ ( x ,x ) for x in pipeline.productions() ]
## Create fields and onchange calls.
project = forms.ChoiceField( choices = listProd, label='',
initial=None )
project.widget.attrs["onchange"]="this.form.submit()"
type = forms.ChoiceField( required=False, label='',
initial=None )
type.widget.attrs["onchange"]="this.form.submit()"
def update( self, POST ):
""" Update Project & Type fields """
proj = pipeline.getChildren( POST.get('project') )
self.fields['type'].choices = [ ( str(x.name), str(x.name) )
for x
in proj.children ]
if POST.get('type'):
path = "/%s/%s"%( POST.get('project'), POST.get('type')
)
children = pipeline.getChildren(path)
self.fields[ 'type' ].choices = [ ( x, x ) for x in
children ]
