Question

我们经常定义这样的架构

        Do Until EndOfStream '= True
            Dim line_to_speak As String = sReader.ReadLine
            Dim vc = Mid(line_to_speak, 1, 1) <- you dont need this

            Select Case vc  <- you dont need this
                Case Is = "/" <- you dont need this
                    voice_index = Val(Mid(line_to_speak, 2, 2)) <- you dont need this
                    srate = Val(Mid(line_to_speak, 5, 2)) <- you dont need this
                    edassistv.lstVoices.SelectedIndex = voice_index <- you dont need this
                    selected_voice = edassistv.lstVoices.SelectedItem <- you dont need this
                Case Else<- you dont need this
                    synth.SelectVoice(selected_voice)
                    synth.Speak(line_to_speak)
            End Select<- you dont need this

        Loop
    Catch ex As Exception
        GoTo finish

我们必须传入与模式匹配的对象，否则无效。但我说要保存一些动态的东西，我甚至不知道它们是什么，例如它可以

var mongoose = require('mongoose');
var Schema = mongoose.Schema;

var Account = new Schema({
    username: String,
    password: String
});

module.exports = mongoose.model('account', Account);

或其他任何东西

{'name':'something',birthday:'1980-3-01'}

那么如何设置架构呢？

Answer 1

Mongoose有Mixed schema type，允许字段为任何对象。

var Account = new Schema({
    username: String,
    password: String,
    anyobject: Schema.Types.Mixed
});

Answer 2

您可以在现有架构定义中使用func sceneViewPannedOneFinger(sender: UIPanGestureRecognizer) { // Get pan distance & convert to radians let translation = sender.translationInView(sender.view!) var xRadians = GLKMathDegreesToRadians(Float(translation.x)) var yRadians = GLKMathDegreesToRadians(Float(translation.y)) // Get x & y radians xRadians = (xRadians / 4) + curXRadians yRadians = (yRadians / 4) + curYRadians // Limit yRadians to prevent rotating 360 degrees vertically yRadians = max(Float(-M_PI_2), min(Float(M_PI_2), yRadians)) // Set rotation values to avoid Gimbal Lock cameraNode.rotation = SCNVector4(x: 1, y: 0, z: 0, w: yRadians) userNode.rotation = SCNVector4(x: 0, y: 1, z: 0, w: xRadians) // Save value for next rotation if sender.state == UIGestureRecognizerState.Ended { curXRadians = xRadians curYRadians = yRadians } // Set preview block setPreviewBlock(sender) } private func setPreviewBlock(recognizer: UIGestureRecognizer) { let point = recognizer.locationInView(sceneView) let options = [SCNHitTestRootNodeKey: sceneView.scene!.rootNode, SCNHitTestClipToZRangeKey: 15, SCNHitTestSortResultsKey: true] let hits = sceneView.hitTest(point, options: options) print(hits.first?.worldCoordinates) }选项，方法是将其作为strict: false构造函数中的第二个参数提供：

示例

Schema

您还可以使用var AccountSchema = new Schema({ Name : {type: String}, Password : {type: String} }, {strict: false}); module.exports = mongoose.model('Account', AccountSchema);类型

Mixed

Mongodb动态模式保存任何数据
