ios User Addproperty not working

Hello Backendless,
I have petProfile table which has the relationship with users.
user: petProfile has 1:N relationship for sure.
When I add a pet, I try to use ‘AddProperty’ bcs I need to add an object into petProfile array in user table.
I can store petProfile well but cannot add this object using AddProperty. Can u check why?
let _ = user.addProperty([“petProfiles” : result!]) -> responds nothing


Backendless.sharedInstance().data.save(profile, response: { (result) in
 print("PetProfile havs been added: \(result!)") 
 dump(result)
 let _ = user?.addProperties(["petProfiles" : result!])
 completionHandler(true)
 }) { (Fault) in
 print("Server reported an error: \(Fault?.description)")
 completionHandler(false)
 }

Hi KenChoi,

func uploadPetProfile(profile: PetProfile, completionHandler: @escaping (_ success: Bool) -> ()) {
 
 
 
 
 let user = Backendless.sharedInstance().userService.currentUser 
 
 
 
 
 Backendless.sharedInstance().data.save(profile, response: { (result) in 
 
 print("PetProfile havs been added: \(result!)") 
 
 dump(result) 
 
 let _ = user?.addProperties(["petProfiles" : result!]) 
 
 completionHandler(true) 
 
 }) { (Fault) in 
 
 print("Server reported an error: \(Fault?.description)") 
 
 completionHandler(false) 
 
 } 
 
 }


You should use setProperty method instead of addProperties.
Also you don’t save your changes.
Add
self.backendless.data.save(user)
after
let _ = user?.setProperty(“petProfiles”, object:result!)

Hi Olga,
The reason I ask this question is that I want to add current instance object into existing array, not set the current instance replacing existing array. Am i understanding right?

Please, check this topic.

You can retrieve all existing relations in array, add new relations to this array and save it.

Yes, I try to use user property function bcs it seems like simpler one I can take.

I will try ur comment above ^^;;

Hello KenChoi,
Is your problem solved?

Regards,
Olga

Yes, I solved in this way

  • first, get the property in the user
  • change as I want
  • second, use ‘setProperty’
  • Third, update user

Thanks for ur help ^^

Hello,

Glad to hear that. Have a nice day.

Regards, Olga

Yeap but please clarify that ‘AddPropery’ function usage.
Quite confuse those functions in the user class

Thanks for ur help once again ^^
