我们可以通过设置状态字段来在同一个界面实现多步向导

视图文件：

your_wizard.xml

<record model="ir.ui.view" id="wizard_with_step_form">
    <field name="name">wizard_with_step.form</field>
    <field name="model">wizard_with_step</field>
    <field name="type">form</field>
    <field name="arch" type="xml">
      <form string="Wizard with step" version="7.0">
       <field invisible="1" name="state" />             
          <group states="step1">
            <field name="name1" />                
          </group>
          <group states="step2">
            <field name="name2" />                
          </group>
          <footer states="step1">
            <button name="action_next" string="Next" type="object" />
          </footer>
          <footer states="step2">
            <button name="action_previous" string="Previous" type="object" />
          </footer>
      </form>
    </field>
   </record>

模型文件：

your_wizard.py

class wizard_with_step(osv.osv_memory):
   _name = 'wizard_with_step'
   _description = 'Wizard with step'
   
   name1 = fields.Char(string="Name 1")
   name2 = fields.Char(string="Name 2")
   state = fields.Selection([('step1', 'step1'),('step2', 'step2')], string="state")
   
   def action_next(self, cr, uid, ids, context=None):
      #your treatment to click  button next 
      #...
      # update state to  step2
      self.write({'state': 'step2',})
      #return view
      return {
            'type': 'ir.actions.act_window',
            'res_model': 'your_wizard',
            'view_mode': 'form',
            'view_type': 'form',
            'res_id': this.id,
            'views': [(False, 'form')],
            'target': 'new',
      }
      
   def action_previous(self, cr, uid, ids, context=None):
      #your treatment to click  button previous 
      #...
      # update state to  step1
      self.write({'state': 'step1',})
      #return view
      return {
            'type': 'ir.actions.act_window',
            'res_model': 'your_wizard',
            'view_mode': 'form',
            'view_type': 'form',
            'res_id': this.id,
            'views': [(False, 'form')],
            'target': 'new',
      }
  }

下面是另一种更简单的方法。

视图文件：

In your wizard.xml:

<record model="ir.ui.view" id="wizard_with_step_form">
    <field name="name">wizard_with_step.form</field>
    <field name="model">wizard_with_step</field>
    <field name="type">form</field>
    <field name="arch" type="xml">
        <form string="Wizard with step" version="7.0">
            <field invisible="1" name="state"/>
            <group states="step1">
                <field name="name1"/>
            </group>
            <group states="step2">
                <field name="name2"/>
            </group>
            <footer states="step1">
                <button name="action_step2" string="Next" type="object"/>
            </footer>
            <footer states="step2">
                <button name="action_step1" string="Previous" type="object"/>
            </footer>
        </form>
    </field>
</record>

模型文件：

name1 = fields.Char(string="Name 1")
name2 = fields.Char(string="Name 2")
state = fields.Selection(
    selection=[
        ('step1', 'Step 1'),
        ('step2', 'Step 2'),
    ],
    string="Current step",
    default="step1",
    readonly=True
)

@api.multi
def action_step1(self):
    self.state = 'step1'
    return {"type": "set_scrollTop"}

@api.multi
def action_step2(self):
    self.state = 'step2'
    return {"type": "set_scrollTop"}

说明：

这种返回类型比“无动作”更好，因为它不会发出警告，并且确保用户被滚动回顶部。
