Single column not being updated in laravel 5 - laravel

Question

I am tying to update a single column of a table messages and I have the following code:
public function messageSeen(Request $request){
$data = Message::find($request->id);
$success = Message::where('id', $request->id)->update(array('is_seen' => 1));
if($success){
return response()->json(['status'=>'success'], 200);
} else {
return response()->json(['status'=>'Data not updated'], 404);
}
}
I am getting the response Data not updated. If you question, does the column is_seen exists? then yes it does. Even I tried fetching the data having id $request->id, it gives the proper data. I wonder why is the data not being updated? Am I doing right thing to update column or is there an way out to update column in different way?
I tried the other way like the following:
public function messageSeen(Request $request){
$id = $request->id;
$result = Message::find($id);
dd($result->message);
$data = array();
$data['is_seen'] = 1;
$data['message'] = $result->message;
$data['user_id'] = $result->user_id;
$data['conversation_id'] = $result->conversation_id;
$this->messages->fill($data);
$success = $this->messages->save();
if($success){
return response()->json(['status'=>'success'], 200);
} else {
return response()->json(['status'=>'Data not updated'], 404);
}
}
But here I am getting unexpected thing with this method. Here I am being able to do dd($result) and being able to get data like this:
#attributes: array:9 [
"id" => 22
"message" => "How are you?\r\n"
"is_seen" => 0
"deleted_from_sender" => 0
"deleted_from_receiver" => 0
"user_id" => 2
"conversation_id" => 1
"created_at" => "2019-09-29 03:42:39"
"updated_at" => "2019-09-29 03:42:39"
]
however, if I tried to do dd($result->message) then I get null! What am I doing wrong?
I tried the following code:
public function messageSeen(Request $request){
$id = $request->id;
$result = Message::find($id);
$data = array();
$data['is_seen'] = 1;
$data['message'] = $result[0]['message'];
$data['user_id'] = $result[0]['user_id'];
$data['conversation_id'] = $result[0]['conversation_id'];
$this->messages->fill($data);
$success = $this->messages->save();
if($success){
return response()->json(['status'=>'success'], 200);
} else {
return response()->json(['status'=>'Data not updated'], 404);
}
}
and it worked but instead of updating it is adding new column when the message is seen. But first I don't understand why do I have to do $result[0]['key'] in the first place.

Answer 1

You need to specify which fields in your table can be mass assigned, by adding or updating the $fillable property of your model:
protected $fillable = [..., 'is_seen', 'message', ...];
This is required for the create() and update() methods, as those accept "mass" variables in the array you pass in. Whereas with save() you have to manually, explicitly, assign the properties on the model, so there is no risk of accidentally saving something you didn't mean to. And this is exactly the behaviour you are seeing - update() is not working, but save() is.

Answer 2

You should try this
public function messageSeen(Request $request) {
$input = Request::all();
$data = Message::find($input['id']);
if (!empty($data)) {
$update = array();
$update['is_seen'] = 1;
$success = Message::where('id', $input['id'])->update($update);
if ($success) {
return response()->json(['status' => 'success'], 200);
} else {
return response()->json(['status' => 'Something went wrong'], 400);
}
} else {
return response()->json(['status' => 'Data not updated'], 404);
}
}
Value depends on data type of is_seen are string or integer
