ODOO里视图开发案例---定义一个像tree、form一样的视图

 odoo里视图模型MVC模式：

例子：在原来的视图上修改他：

var CustomRenderer = KanbanRenderer.extend({
    ....
});

var CustomRendererModel = KanbanModel.extend({
    ....
});

var CustomRendererController = KanbanController.extend({
    ....
});

var  CustomDashboardView=KanbanView.extend({
     config:_extend({},kanbanView.prototype.config,{
         Model:customDashboardModel,
         Renderer:customDashboardRenderer,
         Controller:customDashboardController,
     }),
});

var viewRegistry=require('web.view_registry');
viewRegistry.add('my_custom_view',CustomDashboardView);


最后在视图上引用
<field name="arch" type="xml">
     <kanban js_class="my_custom_view">
           .....
     </kanban>
</field>






定义一个：m2m_group的视图：js部分

class ActWindowView(models.Model):
    _inherit = 'ir.actions.act_window.view'

    view_mode =fields.Selection(selection_add=[('m2m_group','M2m_group')])

class View(models.Model):
    _inherit = 'ir.ui.view'

    type = fields.Selection(selection_add=[('m2m_group', 'M2m Group')])

class Base(models.AbstractModel):
    _inherit = 'base'

    @api.model
    def get_m2m_group_data(self,domain,m2m_field):
        records=self.search(domain)
        result_dict={}
        for record in records:
            for m2m_record in record[m2m_field]:
                if m2m_record.id not in result_dict:
                   result_dict[m2m_record.id]={
                       'name':m2m_record.display_name,
                       'children':[],
                       'model':m2m_record._name
                   }
                result_dict[m2m_record.id]['children'].append({
                    'name':record.display_name,
                    'id':record.id,
                })
        return  result_dict
