如果数据类型从字符串更改为布尔数据存储，则会引发错误

Question

我将我的结构值存储在Google数据存储区中。 这是我的结构：

type Appointment struct {
    ID                    string 
    Appointment Date      string 
    Start Time            string 
    End Time              string 
    Select Specialization string 
    Smoking Status        string
} 

我已经使用数据存储存储了一些数据，但后来将“吸烟状态”字段的数据类型从字符串更改为bool，然后数据存储抛出错误：

{“错误”：{“消息”：“数据存储：无法将字段“吸烟状态”加载到“ simplysthealth.Encounter”中：类型不匹配：字符串与布尔值”}}

有什么可行的解决方案吗？

package main

// I have corrected all of your method names
type Appointment struct {
        ID                   string
        AppointmentDate      string
        StartTime            string
        EndTime              string
        SelectSpecialization string
        SmokingStatus        string
}

type AllOldData struct {
        Data []Appointment
}
type FixedAppointment struct {
        ID                   string
        AppointmentDate      string
        StartTime            string
        EndTime              string
        SelectSpecialization string
        SmokingStatus        bool
}

type FixedData struct {
        Data []FixedAppointment
}

func TypeFixing() FixedData {

        var OldData AllOldData
        var NewData FixedData

        OldData = GetYourAllOldData()

        for i, v := range OldData.Data {
                if v.SmokingStatus == "true" {
                        // other value exchanging
                        NewData.Data[i].SmokingStatus = true
                } else {
                        // other value exchanging
                        NewData.Data[i].SmokingStatus = false
                }
        }

        return NewData // Save the data in a new table or whatever you call it

}

func GetYourAllOldData() AllOldData {
        // A function that returns all old data
        return AllOldData{} // You must return return your all data
}

这是您需要手动执行的操作！
