如何添加入站电子邮件地址和webhook？
我正在建立一个约会风格的应用程序,其中Users可以批准其他用户.我使用Approval模型来跟踪这些关系.每个Approval都有一个user_id和一个approved_id- 批准的用户ID User.它还有rejected_at一个日期时间,表示一个User人拒绝了另一个人.
要向符合条件的用户提供current_user,我必须查询其中任何一个的用户
Approval关系Approval关系只与approved_idas current_user.id(意味着符合条件的用户批准current_user但反过来没有任何关系)User具有Approval非nil rejected_at属性的s,其中approved_id是User或者user_id是current_user.如何创建ActiveRecord查询以查找符合条件的用户？我知道我可以做joins的Approval,但我也想考虑那里是没有Approval关系的User小号!我认为只做两个单独的查询可能更有意义,但我想知道是否可以组合成一个...
我有一个NSData对象.我需要将其字节转换为字符串并作为JSON发送.description返回十六进制并且不可靠(根据各种SO海报).所以我正在看这样的代码:
NSUInteger len = [imageData length];
Byte *byteData = (Byte*)malloc(len);
[imageData getBytes:&byteData length:len];
然后我如何将byteData作为JSON发送？我想发送原始字节.
码:
NSString *jsonBase64 = [imageData base64EncodedString];
NSLog(@"BASE 64 FINGERPRINT: %@", jsonBase64);
NSData *b64 = [NSData dataFromBase64String:jsonBase64];
NSLog(@"Equal: %d", [imageData isEqualToData:b64]);
NSLog(@"b64: %@", b64);
NSLog(@"original: %@", imageData);
NSString *decoded = [[NSString alloc] initWithData:b64 encoding:NSUTF8StringEncoding];
NSLog(@"decoded: %@", decoded);
除了最后一行之外,我得到了一切的价值 - decoded.哪会告诉我原始字节没有格式化为NSUTF8encoding？
我从Xcode停止了运行过程,关闭了后台应用程序.
当我开始关闭它时,模拟器会挂起约20秒,然后提示"删除__app？"
在我MainActivity,我有:
@Override
protected void onResume() {
super.onResume();
checkForCrashes();
checkForTutorial();
checkForUpdates();
setStore();
setup();
}
在setup(),我打电话initializeTabs()回调:
protected void setup() {
final Store s = getStore();
setBackground();
if (s == null) {
unauthorizedHandler();
return;
}
final Context mainActivity = this;
fragments = getTabFragments();
StoresController.getStoreDetails(s, mainActivity, new Callback<StoreDetailDecorator>() {
@Override
public void success(StoreDetailDecorator storeDetailDecorator, Response response) {
s.prettyName = storeDetailDecorator.store.pretty_name;
s.save();
Log.v(TAG, s.prettyName);
TextView toolbar_label = (TextView)findViewById(R.id.toolbar_label);
toolbar_label.setText(MainActivity.getTruncatedMenuName(s.name()));
SummaryTab t1 = (SummaryTab)fragments.get(0);
t1.notifier = (SummaryTabLoadingNotifier)mainActivity;
initializeTabs(s, fragments);
t1.populateReport(); …编辑:Youtube视频演示了这个问题:

编辑:Pasting在这里至关重要.当我粘贴从文本编辑器复制的10 gist.github.com行时,将其喷入1行.
我把它粘贴到gist.github.com
return (
<div className="App">
<h1>Quantum Pilot</h1>
<div className="content">
<div className="box"><About/></div>
<div className="box">HnnYoutube</div>
<div className="box">{buy}</div>
<div className="box">{mykeys}</div>
</div>
<MetamaskPrompt enabled={this.state.metamask}/>
</div>
);
10行,但是 - gist.github.com变成1行,间隔很差.如果我点击"软包装",它会占用2行.
为什么我的新线被销毁？
我从http://scala-ide.org/download/sdk.html下载了适用于Mac 64位的Scala IDE
我打开程序,单击文件>新建,然后查看.
我所在的Coursera教程说我应该看到创建一个新的Scala项目的选项.看起来我有IDE而不是SDK？
我正在尝试遵循本教程的要求imtools。看起来我已经安装了软件包，但是Python编译器找不到它。这里发生了什么？

在顶部状态栏上,我看到"附加到AppName".该项目唯一奇怪的事情是它依赖ZXingWidget进行QR码扫描.
更奇怪的是它适用于同事计算机,但不适用于我的计算机.
尝试删除我的构建目录,没有骰子.
我可以在Xcode 4中从源代码运行其他iPhone项目没有问题.
有没有人见过这个？
