Laravel 5.4 - Update an existing record - php

Question

I'm struggling to update an existing record through an Eloquent Model in Laravel 5.4
I have for creating a record that works perfectly fine, I took it and modified it to try and update the record:
public function commitEdit ($char_edit_id)
{
$edited_character = \DB::table('characters')->where('char_id', $char_edit_id)->first();
$edited_character->campaign_id = 1;
$edited_character->character_name = request('characterName');
$edited_character->Race = request('race');
$edited_character->Sub_Race = request('subRaceField');
$edited_character->Class = request('class');
$edited_character->Level = request('level');
$edited_character->Strength = request('strength');
$edited_character->Dexterity = request('dexterity');
$edited_character->Constitution = request('constitution');
$edited_character->Intelligence = request('intelligence');
$edited_character->Wisdom = request('wisdom');
$edited_character->Charisma = request('charisma');
$levelVar = request('level');
if ($levelVar >= 4) {
$edited_character->Proficiency = 2;
} else if ($levelVar >= 8) {
$edited_character->Proficiency = 3;
}
$edited_character->Trained_Skills = request('skillsField');
$edited_character->Languages = request('languagesField');
$edited_character->Hit_Die = 1;
$edited_character->max_HP = request('max-hp');
$edited_character->Alignment = request('alignment');
$edited_character->Armor_Class = request('armor-class');
$edited_character->Initiative = request('initiative');
$edited_character->Speed = request('speed');
$edited_character->Background = request('background');
$edited_character->update();
return redirect('./characters');
That gives this error:
Call to undefined method stdClass::update()
I have tried using save() but I get the same error with save() instead of update()
Thanks in advance c:

Documentation
If you just need to retrieve a single row from the database table, you may use the first method. This method will return a single StdClass object:
$edited_character is a stdClass, no Eloquent model.
You can try this code:
public function commitEdit ($char_edit_id)
{
$edited_character = \DB::table('characters')->where('char_id', $char_edit_id)->update([
'campaign_id' => 1,
'character_name' => request('characterName'),
'Race' => request('race'),
//others property
]);
}
Or create Characters model which will be extends from Illuminate\Database\Eloquent\Model and use save method:
public function commitEdit ($char_edit_id)
{
$edited_character = Characters::where('char_id', $char_edit_id)-first();
//your code with properties
$edited_character->save();
}

You can try this way:
public function commitEdit ($char_edit_id)
{
$edited_character = Characters::find($char_edit_id);
$edited_character->character_name = request('characterName');
$edited_character->Race = request('race');
$edited_character->Sub_Race = request('subRaceField');
$edited_character->Class = request('class');
$edited_character->Level = request('level');
$edited_character->Strength = request('strength');
$edited_character->Dexterity = request('dexterity');
$edited_character->Constitution = request('constitution');
$edited_character->Intelligence = request('intelligence');
$edited_character->Wisdom = request('wisdom');
$edited_character->Charisma = request('charisma');
$levelVar = request('level');
if ($levelVar >= 4) {
$edited_character->Proficiency = 2;
} else if ($levelVar >= 8) {
$edited_character->Proficiency = 3;
}
$edited_character->Trained_Skills = request('skillsField');
$edited_character->Languages = request('languagesField');
$edited_character->Hit_Die = 1;
$edited_character->max_HP = request('max-hp');
$edited_character->Alignment = request('alignment');
$edited_character->Armor_Class = request('armor-class');
$edited_character->Initiative = request('initiative');
$edited_character->Speed = request('speed');
$edited_character->Background = request('background');
if($edited_character->save()){
return redirect('./characters');
}else{
// show error message
}
}
