Odoo中的one2many表单视图按钮

Question

I would like to ask about one2many field form view with action button.

I have a model with one2many field. I would like to add button in one2many form view, but, when I added that button in view, it only showed in readonly mode. It did not know which model/object should be used, just I think, so how to add the model for that button.

My code like that:

class main_model(osv.osv):
    _name = "main.model"
    _columns = {
         'other_model_ids':fields.one2many('other.model','main_id','Other'),
    }
class other_model(osv.osv):
    _name = "other.model"
    _columns = {
        'name':fields.char('Name'),
        'code':fields.char('Code'),
        'main_id':fields.many2one('main.model','Main'),
    }
...
<field name="model">main.model</field>
<field name="type">form</field>
<field name="arch" type="xml">
    <field name="other_model_ids">
         <tree string="Other Model">
              <field name="name"/>
              <field name="code"/>
         </tree>
         <form string="Other Model">
              <group>
                    <field name="name"/>
                    <button name="generate_code" string="Generate Code" type="object"/>
                    <field name="code"/>
              </group>
         </form>
    </field>
</field>
...

I would like to add that button in one2many form view.

button name="generate_code" string="Generate Code" type="object"...

but that button did not know which model belong this. If you know and have some time, please explain me. Thanks.

Answer 1

In my opinion:

1.You should define the function under the model:

For example:

class other_model(osv.osv):
_name = "other.model"
_columns = {
    'name':fields.char('Name'),
    'code':fields.char('Code'),
    'main_id':fields.many2one('main.model','Main'),
}

@api.one
def generate_code(self):
    pass

2.You can try this:

<field name="model">main.model</field>
<field name="type">form</field>
<field name="arch" type="xml">
    <form string="Main Model">
        <notebook>
            <page string="Other Models">
                <field name="Other Model">
                    <tree>
                        <field name="name"/>
                        <field name="code"/>
                        <button name="generate_code" string="Generate Code" type="object"/>
                    </tree>
                </field>
            </page>
        </notebook>
    </form>
</field>

I wish this will help you.
