why I get ErrorException: Attempt to assign property 'lastMessage' of non-object with lare-CodePudding

Hello everyone actually I'm using laravel API and I'm trying to get this response:

chatsContacts: Array(2)
0:
about: "Cake pie jelly jelly beans. Marzipan lemon drops halvah cake. Pudding cookie lemon drops icing"
avatar: "/static/media/avatar-s-2.d21f2121.jpg"
chat:
id: 1
lastMessage:
message: "If it takes long you can mail me at my mail address."
senderId: 11
time: "2022-06-05T22:55:42.271Z"
[[Prototype]]: Object
unseenMsgs: 0
[[Prototype]]: Object
fullName: "Felecia Rower"
id: 1
role: "Frontend Developer"
status: "offline"

as what you are seeing the chat is inside chatsContacts and the lastMessage is inside chat. I did an attempt to get this response but I get : ErrorException: Attempt to assign property 'lastMessage' of non-object this is the code:

 function listChats($id){
        $types= chat::all()->where('userId', $id);
        $c= chat::all()->where('userId', $id);
        $d=  chat::all()->where('userId', $id);

        foreach ($types as $chats) {
            $chats->chatsContacts = chat::all()->where('userId', $chats->userId); 
        }
        foreach ($c as $chats) {
            $chats->chat = DB::table('chats')->where('id', $chats->id)->get();
            
        foreach ($chats as $m) {
            $m->lastMessage = DB::table('chats')->select('message','time','senderId')->orderBy('time', 'asc')
            ->skip(0)->take(1)->get();
        
        }}
        foreach ($d as $chats) {
            $chats->profileUser = chat::all()->where('userId', $chats->userId); ;    
        }            

                
        return ['chatsContacts' => $types, 'contacts' => $c, 'profileUser' => $d];
  }

I would be veryyy thankful if I get a push to resolve this issue

CodePudding user response：

   foreach ($chats as $m) {
        $m->lastMessage = DB::table('chats')->select('message','time','senderId')->orderBy('time', 'asc')
        ->skip(0)->take(1)->get();
    }}

what is $chats in this line?? maybe this is the reason you get error?

i suggest you to combine you data after all the foreach done.

like this $responsedata['whatever'] = $yourdata $responsedata['whatever2'] = $yourdata2

then you can return $responsedata

CodePudding user response：

Because ::all() returns array not object. Try to change

$types= chat::where('userId', $id)->get();
