我正在设置Devise＆amp;按照我常常做的轨道广播的Omniauth，现在我只使用Rails 5.0.1和ruby 2.3.3
当我去添加用户时，甚至没有使用Omniauth，只需使用基本的电子邮件+密码+确认页面重新加载，错误为“电子邮件不能为空”。我可以看到参数包括电子邮件。
我用Pry来调查 - 事情在这里变得奇怪。
public class Notification extends Service {
String datanews;
String titlenotif;
String destnotif;
MyAsynk asynk;
final String SAVED_TEXT = "saved_text";
String checker;
SharedPreferences sPref;
@Override
public void onCreate() {
super.onCreate();
Timer timer = new Timer();
timer.schedule(new UpdateTimeTask(), 0, 1800000); //тикаем каждые 30 мinute без задержки 1800000
}
class UpdateTimeTask extends TimerTask {
public void run() {
sPref = getSharedPreferences("MyPref",MODE_PRIVATE);
String savedText = sPref.getString(SAVED_TEXT, "");
checker = sPref.getString(savedText, "0");
if(datanews != checker){
asynk = new MyAsynk();
asynk.execute();
createNotification(getApplicationContext());//пушим уведомление
} else {
asynk = new MyAsynk();
asynk.execute();
}
}
}
class MyAsynk extends AsyncTask<Void,Void,StringBuilder> {
@Override
protected StringBuilder doInBackground(Void... voids) {
StringBuilder stringBuilder = new StringBuilder();
String key = "0aa2713d5a1a4aad9a914c9294f6a22b";
try {
URL url = new URL("https://newsapi.org/v1/articles?source=the-next-web&sortBy=latest&apiKey=" + key);
URLConnection uc = url.openConnection();
uc.connect();
BufferedInputStream in = new BufferedInputStream(uc.getInputStream());
int ch;
while ((ch = in.read()) != -1) {
stringBuilder.append((char) ch);
}
} catch (Exception e) {e.printStackTrace();}
return stringBuilder;
}
@Override
protected void onPostExecute(StringBuilder stringBuilder) {
try {
JSONObject jsonObject = new JSONObject(stringBuilder.toString());
JSONArray array = jsonObject.getJSONArray("articles");
for (int i = 0; i < array.length(); i++) {
JSONObject object = array.getJSONObject(i);
String title = object.getString("title");
String desc = object.getString("description");
String newsdata = object.getString("publishedAt");
datanews = newsdata;
titlenotif = title;
destnotif = desc;
}
}
catch (Exception e){e.printStackTrace();}
}
}
private void createNotification(Context context) {
NotificationManager manager = (NotificationManager) context.getSystemService(NOTIFICATION_SERVICE);
NotificationCompat.Builder ncBuilder = new NotificationCompat.Builder(context);
Intent intent = new Intent(this, MainActivity.class);
PendingIntent pIntent = PendingIntent.getActivity(this, 0, intent, 0);
ncBuilder.setVibrate(new long[]{500});
ncBuilder.setLights(Color.WHITE, 3000, 3000);
ncBuilder.setSound(Settings.System.DEFAULT_NOTIFICATION_URI);
ncBuilder.setContentIntent(pIntent);
ncBuilder.setContentTitle(titlenotif + "");
ncBuilder.setContentText(destnotif + "");
ncBuilder.setTicker("You have news!");
ncBuilder.setSmallIcon(R.drawable.news_icon);
ncBuilder.setAutoCancel(true);
manager.notify((int)System.currentTimeMillis(),ncBuilder.build());
}
public IBinder onBind(Intent arg0) {
return null;
}
}
您可以看到，如果我访问@user，它将返回包含该电子邮件的哈希。但是，如果我尝试@ user.email，我会得到零。当我要求@ user.errors时，消息显示电子邮件不能为空。
我一直在这个上打猎。在此先感谢您的帮助！

我相信permitted: false表示您的参数不被允许且无法保存。您是否为Users控制器设置了强大的参数？
