How to update alias column in Laravel - laravel

Question

I want to update records in Postgresql DB and Laravel.
The problem is that alias columns are not in relation with the table, but I made them in first place:
message: "SQLSTATE[42703]: Undefined column: 7 ERROR: column "nivo600" of relation "meas_kanal" does not exist↵LINE 1: update "meas_kanal" set "recordtime" = $1, "nivo600" = $2, "...↵
The function in controller:
$student = Stamboliiski::where('recordtime', $request->get('kanal_id'))
->selectRaw('recordtime')
->selectRaw('max(formattedvalue) filter (where fullname = \'text 1\') as nivo600')
->selectRaw('max(formattedvalue) filter (where fullname = \'text 2\') as razhod600')
->update([
'recordtime' => $request->input('recordtime'),
'nivo600' => $request->input('formattedvalueN'),
'razhod600' => $request->input('formattedvalueR'),
])
->where(function ($query) {
$query->where('fullname', 'like', "text 1")
->orWhere('fullname', 'like', "text 2");
})
->groupBy('recordtime')
->orderBy('recordtime')
->first();
$success_output = '<div class="alert alert-success">The record is updated!</div>';
Model:
class Stamboliiski extends Model
{
protected $connection = 'stamboliiski';
protected $table = 'meas_kanal';
protected $fillable = ['fullname','formattedvalue','recordtime','qualitydesc','statedesc','author','id'];
}
Why?
EDIT 1 after comment of #Dimitri Mostrey:
$student = Stamboliiski::where('recordtime', $request->get('kanal_id'))
->selectRaw('recordtime')
->selectRaw('max(formattedvalue) filter (where fullname = \'text 1\') as nivo600')
->selectRaw('max(formattedvalue) filter (where fullname = \'text 2\') as razhod600')
->where(function ($query) {
$query->where('fullname', 'like', "text 1")
->orWhere('fullname', 'like', "text 2");
})
->groupBy('recordtime')
->orderBy('recordtime')
->first();
$student->recordtime = $request->get('recordtime');
$student->nivo600 = $request->get('formattedvalueN');
$student->razhod600 = $request->get('formattedvalueR');
$student->author = Auth::user()->name;
$student->save();
The error now is this:
message: "SQLSTATE[42703]: Undefined column: 7 ERROR: column "nivo600" of relation "meas_kanal" does not exist↵LINE 1: update "meas_kanal" set "nivo600" = $1, "razhod600" = $2, "a...↵ ^ (SQL: update "meas_kanal" set "nivo600" = 1.86, "razhod600" = 9.76, "author" = John Doe, "updated_at" = 2020-04-30 10:22:28 where "id" is null)"
In this method it uses id column that I don't want, and even I don't know why it used instead using the timestamp.
EDIT 2 on reply of #Uzair Riaz
Unforchantly the problem is still here. After change the controller and model is getting success message, but nothing changes. For example if I want to change value of nivo600 to 1 in recordtime 2020-04-17 00:00:00. After I echo $student in dd:
App\StamboliiskiMeasCanal {#530

It seems that no update is maded...

Answer 1

If those are the only two aliases you are going to use, I suggest overriding the ->fill() method in your model. Map your aliases to the $fillable like so:
class Stamboliiski extends Model
{
protected $fillable = ['fullname', 'formattedvalue', 'recordtime', 'qualitydesc', 'statedesc', 'author', 'id'];
protected $mapping = [
'nivo600' => 'formattedvalue',
'razhod600' => 'formattedvalue'
];
public function fill(array $attributes)
{
foreach ($attributes as $key => $value) {
if (isset($this->mapping[$key])) {
$attributes[$this->mapping[$key]] = $value;
unset($attributes[$key]);
}
}
return parent::fill($attributes);
}
}
Then you can update like so:
$student->update([
'recordtime' => $request->get('recordtime'),
'nivo600' => $request->get('formattedvalueN'),
'razhod600' => $request->get('formattedvalueR'),
'author' => Auth::user()->name
]);
