Question

in current view:
class A:
​x1 = fields.Char()
​y1 = fields.Char()

​x2 = fields.Char()
​y2 = fields.Char()

current view is class A,
I want to put a button on A view, and click this button, the page change to class B, and current view's data passed to class B.
I don't want to make Many2one or One2many,
how to do it ?

In "Class A" define a function for your button:
def open_view_b(self):
​# prepare fields your going to pass in context
​ctx = {'default_x2': self.x1, 'default_y2': self.y2}
return {
​ 	 ​​'name': _('Some name'),
​​'view_mode': 'form',
​'res_model': 'model of b class',
​'type': 'ir.actions.act_window',
​'target': 'current',
​'context': ctx,
​}
