Odoo14 rpc

odoo14中rpc调用分为两种。

一种是外部调用rpc来访问odoo数据，这个时候你需要登录授权。

另一种是我们自己编写的widget小部件或者自定义视图时候通过js通过rpc去获取数据。

这里说的是第二种rpc的使用。

上代码：

    //调用res.users中的自定义的get_userform_action方法
    this._rpc({
        model: 'res.users',
        method: 'get_userform_action',
        args: [[data.val]]//这里就是python函数声明里的*args，当你的方法不是model方法也不是model_create方法的时候，这里一个参数传的是当前model(res.users)的记录id，它会查询id结果作为self去调用get_userform_action
    }).then(function (result){
        self.do_action(result);
    });
 
    //查询数据的方法
    this._rpc({
        model: this.model,
        method: 'read_group',
        domain: [],
        fields: ['color'],
        groupBy: ['color'],
    }).then(function (result) {
        _.each(result, function (r) {
            self.colorGroupData[r.color] = r.color_count;
        });
    });

//自定义的方法
class Users(models.AbstractModel):
    _inherit = 'res.users'
 
    def get_userform_action(self):
        action = self.env.ref('ship_manage.res_company_user_form_action').read()[0]
        action['res_id'] = self.id
        return action
