将 Eureka 表单数据上传到 firebase

Question

我有一个 Eureka 表单视图的用户配置文件。在此 space 中，用户可以更新他们的个人资料。如果用户单击 'Save'，它会调用此函数。

    func saveProfileSettings(){

    let userID = user?.uid
    let formatter = DateFormatter()
    formatter.dateFormat = "yyyy-MM-dd"

    let PROFILE_DISPLAY_NAME_REF: NameRow? = form.rowBy(tag: Constants.PROFILE_DISPLAY_NAME)
    let PROFILE_DISPLAY_NAME = PROFILE_DISPLAY_NAME_REF?.value

    let PROFILE_EMAIL_REF: EmailRow? = form.rowBy(tag: Constants.PROFILE_EMAIL)
    let PROFILE_EMAIL = PROFILE_EMAIL_REF?.value

    let PROFILE_PHONENUMBER_REF: PhoneRow? = form.rowBy(tag: Constants.PROFILE_PHONENUMBER)
    let PROFILE_PHONENUMBER = PROFILE_PHONENUMBER_REF?.value

    let PROFILE_BIRTH_AGE_REF: DateRow? = form.rowBy(tag: Constants.PROFILE_BIRTH_AGE)
    let PROFILE_BIRTH_AGE_CONVERT = PROFILE_BIRTH_AGE_REF?.value
    let PROFILE_BIRTH_AGE = formatter.string(from: PROFILE_BIRTH_AGE_CONVERT!)
    let PROFILE_BIRTH_AGE_String = String(PROFILE_BIRTH_AGE)

    let PROFILE_GENDER_REF: SegmentedRow<String>! = form.rowBy(tag: Constants.PROFILE_GENDER)
    let PROFILE_GENDER = PROFILE_GENDER_REF.value

    let PROFILE_GENDER_INTEREST_REF: SegmentedRow<String>! = form.rowBy(tag: Constants.PROFILE_GENDER_INTEREST)
    let PROFILE_GENDER_INTEREST = PROFILE_GENDER_INTEREST_REF.value

    let uploadPath = databaseRef.child("profiles").child(userID!)

    let dataBlock = ["\(Constants.PROFILE_DISPLAY_NAME)": PROFILE_DISPLAY_NAME!, "\(Constants.PROFILE_EMAIL)": PROFILE_EMAIL!, "\(Constants.PROFILE_PHONENUMBER)": PROFILE_PHONENUMBER!, "\(Constants.PROFILE_BIRTH_AGE)": PROFILE_BIRTH_AGE_String!, "\(Constants.PROFILE_GENDER)": PROFILE_GENDER!, "\(Constants.PROFILE_GENDER_INTEREST)": PROFILE_GENDER_INTEREST!]

    print("DataBlock \(dataBlock)")

    uploadPath.setValue(dataBlock) { (error, datebaseRef) in
        if error != nil{
            print("Error Occured")
        }
        print("Profile Updated!")
    }



}

这个函数的工作是从表单中提取所有数据，将其放入一个数组中，然后将其上传到 firebase。如果用户单击保存并且不更新任何信息，一切都很好，但是如果他们编辑他们的个人资料并单击保存，则会导致错误。见下文。

assertion failed: Duplicate tag profileDisplayName: file /Users/brandonmayhew/Documents/Programming/X-Code Project's/ChristinaApp/Pods/Eureka/Source/Core/BaseRow.swift, line 172

如果您想查看创建表单的代码是什么，它在我的 'viewDidLoad'

override func viewDidLoad() {
    super.viewDidLoad()

    self.startAnimating(Constants.animationSize, message: "Finding Your Profile", type: .ballZigZag)

    //findImageURL()


    //START

    let userID = user?.uid
    print("Logged in user: \(userID!)")


    databaseRef.child("profiles").child(userID!).observe(.value, with: { (snapshot) in


        let data = snapshot.value as? NSDictionary

        let PROFILE_DISPLAY_NAME = data?[Constants.PROFILE_DISPLAY_NAME] as? String
        let PROFILE_UID = data?[Constants.PROFILE_UID] as? String
        let PROFILE_IMAGE = data?[Constants.PROFILE_IMAGE] as? String
        let PROFILE_EMAIL = data?[Constants.PROFILE_EMAIL] as? String
        let PROFILE_PHONENUMBER = data?[Constants.PROFILE_PHONENUMBER] as? String
        let PROFILE_GENDER = data?[Constants.PROFILE_GENDER] as? String
        let PROFILE_GENDER_INTEREST = data?[Constants.PROFILE_GENDER_INTEREST] as? String
        let PROFILE_BIRTH_AGE = data?[Constants.PROFILE_BIRTH_AGE] as? String
        let PROFILE_LATITUDE = data?[Constants.PROFILE_LATITUDE] as? String
        let PROFILE_lONGITUDE = data?[Constants.PROFILE_lONGITUDE] as? String

        self.form +++ Section("Personal Information")

            <<< NameRow(){ row in

                row.title = "Name"
                row.placeholder = "Enter Name"
                row.value = PROFILE_DISPLAY_NAME
                row.tag = "\(Constants.PROFILE_DISPLAY_NAME)"

                }

            <<< EmailRow(){ row in

                row.title = "Email"
                row.placeholder = "Enter Email"
                row.value = PROFILE_EMAIL
                row.tag = "\(Constants.PROFILE_EMAIL)"

            }

            <<< PhoneRow(){ row in

                row.title = "Phone Number"
                row.placeholder = "Enter Phone Number"
                row.value = PROFILE_PHONENUMBER
                row.tag = "\(Constants.PROFILE_PHONENUMBER)"

            }

            <<< DateRow(){ row in
                row.title = "Your Birth Year"

                //Convert 'PROFILE_BIRTH_AGE' string to NSDATE
                let date = NSDate()
                let dateFormatter = DateFormatter()
                dateFormatter.dateFormat = "yyyy-MM-dd"
                let formattedDate = dateFormatter.date(from: PROFILE_BIRTH_AGE!)

                row.value = formattedDate
                row.tag = "\(Constants.PROFILE_BIRTH_AGE)"
            }



            +++ Section("Dating Settings")

            <<< SegmentedRow <String> (){ row in
                row.title = "I am"
                row.options = ["Male", "Female"]
                row.value = PROFILE_GENDER
                row.tag = "\(Constants.PROFILE_GENDER)"
            }

            <<< SegmentedRow <String> (){ row in
                row.title = "I'm interested in"
                row.options = ["Male", "Female"]
                row.value = PROFILE_GENDER_INTEREST
                row.tag = "\(Constants.PROFILE_GENDER_INTEREST)"
            }

            +++ Section("Save Profile")
            <<< ButtonRow() {
                [=12=].title = "Save"
                }
                .onCellSelection {  cell, row in

                    self.saveProfileSettings()

            }

            +++ Section("Come Back Later")
            <<< ButtonRow() {
                [=12=].title = "Sign Out"
                }
                .onCellSelection {  cell, row in

                    self.signOut()
            }




        self.stopAnimating()


    })

    //STOP


}

我不知道是什么导致了这个错误！

Answer 1

您遇到的问题是由于添加了具有相同标记字符串值的行或部分引起的。在 Eureka Forms 中，单元格甚至部分的标签应该是唯一的，因此如果您添加具有相同标签的 2 行，这将导致断言异常

您在代码的 多个部分 中有这种行为，但我将以 name 行为例

 <<< NameRow(){ row in

                row.title = "Name"
                row.placeholder = "Enter Name"
                row.value = PROFILE_DISPLAY_NAME
                row.tag = "\(Constants.PROFILE_DISPLAY_NAME)"  

                }

如您所见，row.tag = "\(Constants.PROFILE_DISPLAY_NAME)" 这是导致问题的行，我假设 Constants.PROFILE_DISPLAY_NAME 是在项目的某些部分定义的 String，这个字符串不t 改变，当你要从这个方法添加你的第二个结果时

databaseRef.child("profiles").child(userID!).observe(.value, with: { (snapshot) in

您的应用程序崩溃，因为您第二次添加 Constants.PROFILE_DISPLAY_NAME 具有相同的值 "profileDisplayName"

解决这个问题的方法

作为此问题的可能解决方案，您可以为每个获取的用户附加一个唯一值，比如 userID

NameRow 大小写的固定代码

 <<< NameRow(){ row in

                row.title = "Name"
                row.placeholder = "Enter Name"
                row.value = PROFILE_DISPLAY_NAME
                row.tag = "\(Constants.PROFILE_DISPLAY_NAME)\(userID)"  

                }
