I'm converting a TG1 app with TG1 style widgets and am finding that a
code pattern implemented to add widgets on the fly in TG1 doesn't work
in TG2/TW. Basically, in an existing form's update_params method,
new fields were being added to a fieldset based upon parameters of the
request/data in model. This strategy doesn't seem to work in TW. So,
my questions is what is the best way to create a form that adds
widgets dynamically?
So far it seems that I need to instantiate a new form widget object
for each request and pass it a fields parameter that is the set of
fields needed for the given request. For example,
myfields = [TextField("a"), TextField("b")]... etc
myform = MyForm("formname", fields=myfields)
myform.display(**params) # pass non-field items in display.
Is this the best approach, or is there a better way that can more
mimic what was possible with TG1 widgets?
