How in Laravel filter by relationship? - laravel

Question

I have two models which linked with each other:
class Task extends Model{
public function user(){
return $this->belongsTo('App\User', 'user_id');
}
}
class User extends Model{
public function tasks(){
return $this->hasMany('App\Task', 'user_id');
}
}
Now I want to create some search or filter system.
There is a form where the user can choose Task only then the User's parameters (age, sex etc)
How can I do this kind of things? I tried to use newQuery on relation but...
Any help, thanks

Answer 1

I hope i understood you well.
Use nested where and whereHas as such
$tasks = Task::where('condition', $var)
->orWhereHas('user', function($q) use ($var){
$q->where('condition', 'LIKE', '%'. $var.'%');
});

try this. i hope it will work for you.
use join to get data from two tables
function getBuildings($request) {
if (isset($request->keyword) && $request->keyword != '') {
$data = $this->where(function($query) use ($request) {
$query->orWhere('users.column_name', 'LIKE', '%' . $request->keyword . '%');
$query->orWhere('users.column_name', 'LIKE', '%' . $request->keyword . '%');
});
}
$datacount = $this->count();
$dataArray = $this->select('users.*,task.whatever data you want to get from task');
if ($request->length == -1) {
$dataArray = $dataArray->get();
} else {
$dataArray = $dataArray->skip($request->start)->take($request->length)->get();
}
return [$datacount, $dataArray];
}
