Odoo14 rpc

odoo14中rpc調用分為兩種。

一種是外部調用rpc來訪問odoo數據，這個時候你需要登錄授權。

另一種是我們自己編寫的widget小部件或者自定義視圖時候通過js通過rpc去獲取數據。

這里說的是第二種rpc的使用。

上代碼：

    //調用res.users中的自定義的get_userform_action方法
    this._rpc({
        model: 'res.users', 
        method: 'get_userform_action',
        args: [[data.val]]//這里就是python函數聲明里的*args，當你的方法不是model方法也不是model_create方法的時候，這里一個參數傳的是當前model(res.users)的記錄id，它會查詢id結果作為self去調用get_userform_action
    }).then(function (result){
        self.do_action(result); 
    });

    //查詢數據的方法
    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;
        });
    });

//自定義的方法
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

//Python   rpc參數傳遞源碼
def _call_kw_model(method, self, args, kwargs):
    context, args, kwargs = split_context(method, args, kwargs)
    recs = self.with_context(context or {})
    _logger.debug("call %s.%s(%s)", recs, method.__name__, Params(args, kwargs))
    result = method(recs, *args, **kwargs)
    return downgrade(method, result, recs, args, kwargs)

    result = method(recs, *args, **kwargs)
    return downgrade(method, result, recs, args, kwargs)

    """ Invoke the given method ``name`` on the recordset ``model``. """
    method = getattr(type(model), name)
    api = getattr(method, '_api', None)
    if api == 'model'://這里將模型分成了三種走向，三種走向對參數的處理不一樣
        result = _call_kw_model(method, model, args, kwargs)
    elif api == 'model_create':
        result = _call_kw_model_create(method, model, args, kwargs)

    model.flush()
