Question

我正在使用Odoo 10并尝试覆盖股票 quants_get_preferred_domain 方法。

我的代码：

/**
 * Try to extract a hardware MAC address from a given IP address using the
 * ARP cache (/proc/net/arp).<br>
 * <br>
 * We assume that the file has this structure:<br>
 * <br>
 * IP address       HW type     Flags       HW address            Mask     Device
 * 192.168.18.11    0x1         0x2         00:04:20:06:55:1a     *        eth0
 * 192.168.18.36    0x1         0x2         00:22:43:ab:2a:5b     *        eth0
 *
 * @param ip
 * @return the MAC from the ARP cache
 */

public static String getMacFromArpCache(String ip) {
    if (ip == null)
        return null;
    BufferedReader br = null;
    try {
        br = new BufferedReader(new FileReader("/proc/net/arp"));
        String line;
        while ((line = br.readLine()) != null) {
            String[] splitted = line.split(" +");
            if (splitted != null && splitted.length >= 4 && ip.equals(splitted[0])) {
                // Basic sanity check
                String mac = splitted[3];
                if (mac.matches("..:..:..:..:..:..")) {
                    return mac;
                } else {
                    return null;
                }
            }
        }
    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        try {
            br.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    return null;
}

我得到一个错误：

 public ArrayList<InetAddress> getConnectedDevices(String YourPhoneIPAddress) {
        ArrayList<InetAddress> ret = new ArrayList<InetAddress>();

        LoopCurrentIP = 0;

        String IPAddress = "";
        String[] myIPArray = YourPhoneIPAddress.split("\\.");
        InetAddress currentPingAddr;


        for (int i = 0; i <= 255; i++) {
            try {

                // build the next IP address
                currentPingAddr = InetAddress.getByName(myIPArray[0] + "." +
                        myIPArray[1] + "." +
                        myIPArray[2] + "." +
                        Integer.toString(LoopCurrentIP));
                ad = currentPingAddr.toString();   /////////////////
                Log.d("MyApp",ad);                 //////////////

                // 50ms Timeout for the "ping"
                if (currentPingAddr.isReachable(50)) {

                    ret.add(currentPingAddr);
                    ad = currentPingAddr.toString();        /////////////////
                    Log.d("MyApp",ad);                     //////////////
                }
            } catch (UnknownHostException ex) {
            } catch (IOException ex) {
            }

            LoopCurrentIP++;
        }
        return ret;
    }

装饰器有什么作用？在v10上如何正确调用旧的api方法？

Answer 1

似乎您正在将方法装饰器定义从@api.model更改为@api.v7

您可以在方法quants_get_preferred_domain的代码中进行检查。您应该可以将方法覆盖定义为：

@api.model
def quants_get_preferred_domain(self, qty, move, ops=False, lot_id=False, domain=None, preferred_domain_list=[]):

您还应该检查您的Odoo版本是否已过时，从而可能在早期的Odoo 10版本中解决了一些问题
