I am a little confused. I dont think I am using tw2.core.Page. AdminPage is
just another class in the same file that fills the left_sidebar with a
couple links, like:
class AdminPage(ATDbPage):
left_sidebar = [
LinkField(
...
and nothing else.
self.widget does the following:
def widget(self,w,kw={}):
if kw.get('export'):
return w.export_data(request)
else:
w = w.request(request)
return dict(w=w,kw=kw,page=self.page)
I have seen the example you are linking, but that does not help. I am able
to prefill any value with a pre-defined value already. The problem is, that
I want to prefill it with a value taken from kw (from the URL). In fact, I
need it to complain if a certain value ('customer_id') is NOT passed in the
URL.
Anyone got any ideas?
