This is a question better suited to the ToscaWidgets mailing list, so you
might want to ask there for a better answer.
To set the currently selected genre simply pass to the form display call a
value={} parameter that contains the key of the field and the value it
should be set to.
To filter the Genre you have multiple options, the one I prefer is usually
to override the prepare method of the form to perform such actions.
the prepare method is called right before displaying the widget, so you can
change there any property depending on the context.
I usually do something like:
def prepare(self):
set_child_value(self, 'entry_type', 'options', [1,2,3])
super(MyCustomForm, self).prepare()
where set_child_value is a function that looks like:
def set_child_value(w, childname, property, value):
if w.child:
w = w.child
for c in w.children:
if c.key == childname:
setattr(c, property, value)
break
maybe one of the tw2 guys has a better solution for this.
