如何在Python端创建扩展窗体视图？

Question

我想创建动态视图，所以我想在python一边创建视图。但是，当我尝试保存视图“arch_base”字段未设置。有人能告诉我有什么问题吗？这里是我的功能

@api.onchange('field_id') 
def create_validation_button(self): 
    model = self.field_id.model_id.model 
    model_view = self.env['ir.ui.view'].search([("model", "=", model), ('type', "=", "form")]) 
    arch = '<xpath expr="//header" postition="inside"><button string="Add Followers" type="object" name="add_project_followers" /></xpath>' 
    if model_view: 
     self.view_id = None 
     self.env['ir.ui.view'].search(
      [("model", "=", model), ('name', "=", 'validation.' + model_view.name)]).unlink() 
     view_data = {'name': 'validation.' + model_view.name, 'type': 'form', 'model': model, 'priority': 1, 
        'inherit_id': model_view.id, 
        'mode': 'extension', 
        'arch_base': arch.encode('utf-8')} 
     view = self.env["ir.ui.view"].create(view_data) 
     self.view_id = view

字段名arch不arch_base所以设定为：

view_data = {'name': 'validation.' + model_view.name, 'type': 'form', 'model': model, 'priority': 1, 
        'inherit_id': model_view.id, 
        'mode': 'extension', 
        'arch': arch.encode('utf-8')}
