I want to make a chat app. So I can get a list of patient but the top last message doesn’t have the patient.
How to solve my problem.

PHP :

$appointment = Appointment::with([
    'upcoming.consultant' => function($query) use ($user) {
        $query->where('consultant_id', $user->consultant_id);
    },
    'patient',
    'conversation' => function($query) {
        $query->latest();
    }
])
->groupBy('patient_id')
->get('patient_id');

Result Json Data :

            "deleted_at": null
        }
    }
]

With groupBy
(Actually I want this way with last message)

PHP :

$appointment = Appointment::with([
    'upcoming.consultant' => function($query) use ($user) {
        $query->where('consultant_id', $user->consultant_id);
    },
    'patient',
    'conversation' => function($query) {
        $query->latest();
    }
])->get();

Result Json Data :

[
    {
        "patient_id": 4,
        "upcoming": null,
        "patient": {},
        "conversation": null
    },
    {
        "patient_id": 5,
        "upcoming": null,
        "patient": {},
        "conversation": null
    }
]

to retrieve a list of appointments grouped by patient ID, with the last conversation message for each patient. However, the resulting JSON data only contains patient ID, upcoming appointment details, patient details, and conversation details, but not the patient name.

To include the patient name in the resulting JSON data, you can modify your code to include the first_name and last_name fields from the patient table in the select statement
```
$appointment = Appointment::with([
        'upcoming.consultant' => function($query) use ($user){
            $query->where('consultant_id', $user->consultant_id);
        },
        'patient' => function($query) {
            $query->select('patient_id', 'salutation', 'first_name', 'last_name');
        },
        'conversation' => function($query) {
            $query->latest();
        }
    ])
    ->groupBy('patient_id')
    ->get(['patient_id']);
```
This will select only the patient_id, salutation, first_name, and last_name fields from the patient table, and include them in the resulting JSON data. You can adjust the select statement to include more fields from the patient table if needed.

Note that the resulting JSON data will only include the fields that are selected in the get method. If you need to include more fields in the JSON data, you should add them to the get method. This will include the upcoming, patient, and conversation fields in the resulting JSON data.
```
$appointment = Appointment::with([
        'upcoming.consultant' => function($query) use ($user){
            $query->where('consultant_id', $user->consultant_id);
        },
        'patient' => function($query) {
            $query->select('patient_id', 'salutation', 'first_name', 'last_name');
        },
        'conversation' => function($query) {
            $query->latest();
        }
    ])
    ->groupBy('patient_id')
    ->get(['patient_id', 'upcoming', 'patient', 'conversation']);
```
