我只是无法更改"密码重置说明"电子邮件的主题.我在Mailer中更改了notifer.rb以覆盖Devise默认电子邮件主题.但它不起作用.

在我的应用程序中,Devise .yml文件中有默认的电子邮件主题.但是我希望通过从数据库中提取数据来改变它.

目的 - 使用javascript获取特定用户的Twitter粉丝

我已尝试将以下代码作为POC-

$(document).ready(function() {
    // Handler for .ready() called.

    $.ajax({
        url: "https://api.twitter.com/1.1/followers/ids.json?callback=?",
        type: "GET",
        data: { cursor: "-1", 
                screen_name: "twitterapi" },
        cache: false,
        dataType: 'json',

        success: function(data) { alert('hello!'); console.log(data);},
        error: function(html) { alert(html); },
        beforeSend: setHeader
    });


    function setHeader(xhr) {
        if(xhr && xhr.overrideMimeType) {
            xhr.overrideMimeType("application/j-son;charset=UTF-8");
        }

        //var nonce = freshNonce();
        //var timestamp = freshTimestamp();
        //var signature = sign(nonce,timestamp);

        //alert(signature);
        //alert(accessToken+"-"+consumerKey);
        //alert(oauth_version+"-"+oauth_signature_method);
        xhr.setRequestHeader('Authorization','OAuth');
        xhr.setRequestHeader('oauth_consumer_key', 'HdFdA3C3pzTBzbHvPMPw');
        xhr.setRequestHeader('oauth_nonce', '4148fa6e3dca3c3d22a8315dfb4ea5bb');
        xhr.setRequestHeader('oauth_signature','uDZP2scUz6FUKwFie4FtCtJfdNE%3D');
        xhr.setRequestHeader('oauth_signature_method', 'HMAC-SHA1');
        xhr.setRequestHeader('oauth_timestamp', '1359955650');
        xhr.setRequestHeader('oauth_token', '1127121421-aPHZHQ5BCUoqfHER2UYhQYUEm0zPEMr9xJYizXl');
        xhr.setRequestHeader('oauth_version', '1.0');
    }

}); …

用户可以设置多个警报.在这种情况下,我将报警数据存储到数据库中并创建一个PendingIntent唯一的requestCode.实际上我正在使用数据库的行ID作为requestCode警报触发时我可以从数据库中获取该特定警报的其他信息.

从我设定意图的地方:

private void setInstantAlarm(Calendar timeFromNow, int pos){
    try{
        Intent intent = new Intent(context, AlarmReceiverActivity.class);
        PendingIntent pendingIntent =
                PendingIntent.getActivity(context, pos, intent, PendingIntent.FLAG_CANCEL_CURRENT);
        AlarmManager am = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
        am.set(AlarmManager.RTC_WAKEUP, timeFromNow.getTimeInMillis(), pendingIntent);

    }catch (NumberFormatException e){
        Toast.makeText(context, "Something went wrong!", Toast.LENGTH_SHORT).show();
    }
}

在我的Alarm接收器类中,我想要我设置为的行ID requestCode:

public class AlarmReceiverActivity extends Activity {
    private MediaPlayer mMediaPlayer;
    private PowerManager.WakeLock mWakeLock;

    @Override
    public void onCreate(Bundle saveInstanceState){
        super.onCreate(saveInstanceState);
        PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
        mWakeLock = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK, "My Wake Log");
        mWakeLock.acquire();

        this.requestWindowFeature(Window.FEATURE_NO_TITLE); …

说,我有一个数组:

a = [1,2]

和

n = 3

我想要这样的输出:

[[1, 1, 1], [1, 1, 2], [1, 2, 1], [1, 2, 2], [2, 1, 1], [2, 1, 2], [2, 2, 1], [2, 2, 2]]

这是n来自数组的元素长度的所有可能组合a.

最重要的是我使用的是ruby 1.8.7
