Hi everybody,
Sorry for re-opening this thread, but I'm trying without success to add a
cancel button to a CRUD form.
Here my controller:
def insertnews():
form = crud.create(db.news)
form.add_button("cancel",URL(r=request,f='index'))
return dict(form=form)
Here my view:
{{=form.custom.begin}}
Body:
<div>{{=form.custom.widget.body}}</div>
{{=form.custom.submit}}
{{=form.custom.cancel}}
{{=form.custom.end}}
Where am I wrong?
Cheers,
David
