PushRow With Custom Object With Eureka Forms

Question

I'm having trouble to use a custom Object in Eureka Form, I'm trying to load the objects from a Rest Service, I'm using Alamofire to get the options, Im using row.options.append to fill the data, and when I select the cell I get an error assertion failed: Duplicate tag Building

Here is my class that conforms to the Equatable Protocol

class Building: Mappable, Equatable {
   var name_building: String?
   var id_building: Int?

   required init?(){
   }

   required init?(_ map: Map){   
   }

   func mapping(map: Map) {
      id_building <- map["id_building"]
      name_building <- map["name_building"]
   }
}

func == (lhs: Building, rhs: Building) -> Bool {
   return lhs.id_building == rhs.id_building
}

And here is the Form

import UIKit
import Eureka
import CoreLocation
import Alamofire
import KeychainAccess
import ObjectMapper
import SnapKit

class UserViewController: FormViewController {


    override func viewDidLoad() {
        super.viewDidLoad()


        self.title = "Perfil del Usuario"

        // Do any additional setup after loading the view.
        form +++ Section("Datos Generales")
            <<< NameFloatLabelRow("kName") {
                $0.title = "Nombre"
            }
            <<< TextFloatLabelRow("kLastName") {
                $0.title = "Apellidos"
            }

                $0.title = "Email"

            }

                $0.title = "¿Estoy dispuesto a dar Aventones?"

            }

            +++ Section("Trabajo")

            }

            <<< ButtonRow() { (row: ButtonRow) -> Void in
                row.title = "GUARDAR"

                    print("Salvando Informacion")

                    let homeDepartureTimeRow: TimeInlineRow! = self.form.rowByTag("kHomeDepartureTime")
                    let buildingRow: PushRow<Building>! = self.form.rowByTag("kBuilding")
                    let buildingEnterTimeRow: TimeInlineRow! = self.form.rowByTag("kEnterTime")
                    let buildingExitTimeRow: TimeInlineRow! = self.form.rowByTag("kExitTime")

                    let user = User()

                    user.email = emailRow.value
                    user.name = nameRow.value
                    user.lastName = lastNameRow.value

                    user.phone = phoneRow.value
                    user.id_type = riderRow.value == true ? 1 : 2
                    user.homeDepartureDate = homeDepartureTimeRow.value
                    user.jobEnterTime = buildingEnterTimeRow.value
                    user.jobExitTime = buildingExitTimeRow.value
                    user.id_building = 3

                    let location = locationRow.value! as CLLocation
                    user.latitude = location.coordinate.latitude
                    user.longitude = location.coordinate.longitude

                    let JSONString = Mapper().toJSONString(user, prettyPrint: false)
                    let mappedObject = Mapper<User>().map(JSONString)


                    let request = "requesttoCreateUser"

                    Alamofire.request(.POST, request, parameters: Mapper().toJSON(user), encoding: .JSON)
                        .validate()
                        .responseJSON { response in
                            switch response.result {
                            case .Success:
                                print("Validation Successful")
                            case .Failure(let error):
                                print(error)
                            }
                    } 

                })

        self.getBuilding();

    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    func getBuilding(){
        let buildingRow: PushRow<Building>! = self.form.rowByTag("kBuilding")

        let request = "requestToGetBuildings"

        Alamofire.request(.GET, request).responseArray { (response: Response<[Building], NSError>) in

            let buildingsArray = response.result.value

            if let buildingsArray = buildingsArray {
                for building in buildingsArray {
                    buildingRow.options.append(building)
                }
            }
        }
    }

}

And It crashes here in the Eureka class BaseRow.swift

    final func wasAddedToFormInSection(section: Section) {
        self.section = section
        if let t = tag {
            assert(section.form?.rowsByTag[t] == nil, "Duplicate tag \(t)")
            self.section?.form?.rowsByTag[t] = self
            self.section?.form?.tagToValues[t] = baseValue as? AnyObject ?? NSNull()
        }
        addToRowObservers()
        evaluateHidden()
        evaluateDisabled()
    }

Answer 1

As mentioned here.

All you need to do is conform your model to CustomStringConvertible protocol.

This is because the default implementation of SelectorViewController uses String(option) as the tag for your PushRow rows

So your class should look like this:

class Building: Mappable, Equatable,CustomStringConvertible {
   var name_building: String?
   var id_building: Int?
   var description: String {

        return name_building
    }
   required init?(){
   }

   required init?(_ map: Map){   
   }

   func mapping(map: Map) {
      id_building <- map["id_building"]
      name_building <- map["name_building"]
   }
}

func == (lhs: Building, rhs: Building) -> Bool {
   return lhs.id_building == rhs.id_building
}
