Answer 1

I think you have given the wrong model name in following field.
'epic_owner':fields.many2one('Agile.assetid.name','Asset ID')
Here instead of "Agile.assetid.name" you have to give "assetid.name" if you want to manage M2O of last model "assetid.name". I think no model have capital letter.
I think this will resolve your issue.
