如何在FormFlow中基于其他字段的值来打开和关闭不同的字段 [英] How to set different fields on and off on basis of value of other field in FormFlow
问题描述
我正在使用FormFlow使用botFrameWork(C#)构建我的机器人.我想让用户从四个报告中选择一个，并希望根据选择来打开和关闭某些字段，并只询问与选择相关的那些问题.
I am using FormFlow to build my bot using botFrameWork(C#). I want to ask user to choose one of four reports and on the basis of selection I want to turn on and off certain fields and ask only those questions which are relevant to the selection.
Follwoing是报告类型的枚举:
Follwoing is the enum for report types:
public enum ReportType
{
Application = 1,
Emotion,
AppVsEmotion,
Help
}
以下是所有字段:
public bool AskToChooseReport = true;
[Prompt("What kind of report you would like? {||}")]
public ReportType? Report { get; set; }
[Prompt("What is the application name?")]
public string ReportApplicationName { get; set; }
[Prompt("Please enter the emotion name? {||}")]
public string EmotionName { get; set; }
[Prompt("What is starting date (MM-DD-YYYY) for report?{||}")]
public string StartDate { get; set; }
[Prompt("What is the end date (MM-DD-YYYY) for report? {||}")]
public string EndDate { get; set; }
public string ReportRequest = string.Empty;
我有四种情况:
案例1:如果用户选择 Application ，那么我只想问用户有关 ReportApplicationName ， StartDate ， EndDate
Case 1: If user slects Application, Then i only want to ask user about ReportApplicationName, StartDate, EndDate
案例2:如果用户选择 Emotion ，那么我只想问用户有关 EmotionName 和 StartDate ， EndDate
Case 2: If user selects Emotion, Then i only want to ask user about EmotionName and StartDate, EndDate
案例3:如果用户选择 AppVsEmotion ，则我想向用户询问 ReportApplicationName ， EmotionName 和 StartDate ，结束日期
Case 3: If user selects AppVsEmotion, The i want to ask user about both ReportApplicationName, EmotionName and StartDate, EndDate
案例4:如果用户选择 Help ，那么我只想问有关 ReportApplicationName ， StartDate ， EndDate >
Case 4: If user selects Help, then i only want to ask about ReportApplicationName, StartDate, EndDate
我尝试执行以下操作，但不起作用:
I tried to do following but it doesn't work:
public static IForm<StandardInfoForm> BuildForm()
{
#pragma warning disable CS1998 // Async method lacks 'await' operators and will run synchronously
var parser = new Parser();
return new FormBuilder<StandardInfoForm>()
.Message("Welcome to reporting information!!")
.Field(new FieldReflector<StandardInfoForm>( nameof(Report))
.SetActive( state => state.AskToChooseReport)
.SetNext( (value, state) =>
{
var selection = (ReportType)value;
if (selection == ReportType.Application)
{
state.ReportRequest = "application";
return new NextStep(new[] { nameof(ReportApplicationName) });
}
else if (selection == ReportType.Emotion)
{
state.ReportRequest = "emotion";
return new NextStep(new[] { nameof (EmotionName) });
}
else if (selection == ReportType.AppVsEmotion)
{
state.ReportRequest = "application,emotion";
return new NextStep(new[] { nameof (ReportApplicationName), nameof(EmotionName) });
}
else if (selection == ReportType.Help)
{
state.ReportRequest = "help";
return new NextStep(new[] { nameof(ReportApplicationName) });
}
else
{
return new NextStep();
}
}))
.Field(nameof(StartDate))
.Field(nameof(EndDate), EndReportDateActive)
.Confirm("Would you like to confirm.Yes or No")
#pragma warning restore CS1998 // Async method lacks 'await' operators and will run synchronously
.Build();
}
如果我太天真，请帮助我.我试图遵循此: 更改Microsoft Bot FrameWork中的消息流
Please help me if I am being too naive. I have tried to follow this: Change Flow Of Message In Microsoft Bot FrameWork
推荐答案
Microsoft.Bot.Builder.FormFlow.FormCanceledException，因为ReportApplicationName不是表单构建器中的字段之一.如果将.Field(nameof(ReportApplicationName))添加到内部版本，则不会发生该异常.
Microsoft.Bot.Builder.FormFlow.FormCanceledException is happening because ReportApplicationName is not one of the fields in the form builder. If you add .Field(nameof(ReportApplicationName)) to the build, the exception will not occur.
您还需要将.Field的ActiveDelegate用于ReportApplicationName和EmotionName步骤，因为有时您想跳过它们.从ActiveDelegate返回false将完成此操作.
You'll also need to use the .Field's ActiveDelegate for the ReportApplicationName and EmotionName steps, since sometimes you want to skip them. Returning false from the ActiveDelegate will accomplish this.
注意:我在枚举中将情感"更改为感觉"，因为FormBuilder遇到了Emotion和AppVsEmotion之间相似性的麻烦，但这应该可以使您朝正确的方向前进:
Note: I changed Emotions to Feelings in the enum, because FormBuilder was having trouble with the similarity between Emotion and AppVsEmotion This should get you going in the right direction though:
public enum ReportType
{
Application = 1,
Feelings,
AppVsEmotion,
Help
}
[Serializable]
public class StandardInfoForm
{
public bool AskToChooseReport = true;
[Prompt("What kind of report you would like? {||}")]
public ReportType? Report { get; set; }
[Prompt("What is the application name? {||}")]
public string ReportApplicationName { get; set; }
[Prompt("Please enter the emotion name? {||}")]
public string EmotionName { get; set; }
[Prompt("What is starting date (MM-DD-YYYY) for report?{||}")]
public string StartDate { get; set; }
[Prompt("What is the end date (MM-DD-YYYY) for report? {||}")]
public string EndDate { get; set; }
public string ReportRequest = string.Empty;
public static IForm<StandardInfoForm> BuildForm()
{
var parser = new Parser();
return new FormBuilder<StandardInfoForm>()
.Message("Welcome to reporting information!!")
.Field(new FieldReflector<StandardInfoForm>(nameof(Report))
.SetActive(state => state.AskToChooseReport)
.SetNext(SetNext))
.Field(nameof(ReportApplicationName), state => state.ReportRequest.Contains("application"))
.Field(nameof(EmotionName), state => state.ReportRequest.Contains("emotion"))
.Field(nameof(StartDate))
.Field(nameof(EndDate), EndReportDateActive)
.Confirm("Would you like to confirm.Yes or No")
.Build();
}
private static NextStep SetNext(object value, StandardInfoForm state)
{
var selection = (ReportType)value;
if (selection == ReportType.Application)
{
state.ReportRequest = "application";
return new NextStep(new[] { nameof(ReportApplicationName) });
}
else if (selection == ReportType.Feelings)
{
state.ReportRequest = "emotion";
return new NextStep(new[] { nameof(EmotionName) });
}
else if (selection == ReportType.AppVsEmotion)
{
state.ReportRequest = "application,emotion";
return new NextStep(new[] { nameof(ReportApplicationName) });
}
else if (selection == ReportType.Help)
{
state.ReportRequest = "help";
return new NextStep(new[] { nameof(ReportApplicationName) });
}
else
{
return new NextStep();
}
}
