i filled everything in form view after that i am clicking on save button to save the record ,after saving the record view mode should be list view or tree view not form view how to do it?

i tried like this-

@api.multi

def tree_view_action(self):

return {

"name": _("Dummy Name"),

'view_mode': 'tree,form',

'view_type': 'form',

"res_model": 'assets.creation',

"type": 'ir.actions.act_window',

"target": "current",

}

----------and this method i called in create method

@api.model

def create(self,vals):

res = super(Equipment,self).create(vals)

res.tree_view_action()

return res
