Laravel Belongs To Not working - php

Question

this should be quite simple but i don't know what wrong . i have the following migrations .
create_players_table
public function up()
{
Schema::create('players', function (Blueprint $table) {
$table->increments('id');
$table->integer('club_id');
$table->string('first_name');
$table->string('last_name');
$table->double('price', 3, 2);
$table->enum('position', ['goalkeeper','defender','Midfielder','Striker']);
$table->timestamps();
});
}
create_clubs_table
public function up()
{
Schema::create('clubs', function (Blueprint $table) {
$table->increments('id');
$table->string('name');
$table->string('location');
$table->timestamps();
});
}
The relationship is straight forward as one player has one team (One to one) and one team can have many players (One to Many ) . The problem is i want to list all the players with their respective teams but somehow i end up with errors . This is my player model .
class Player extends Model
{
public function club()
{
return $this->belongsTo('App\Club');
}
}
And here is the controller :
public function index()
{
$players=Player::find(1);
echo $players->club()->location;
}
I get this error
ErrorException in TeamController.php line 15: Undefined property: Illuminate\Database\Eloquent\Relations\BelongsTo::$name
Any help will be appreciated...

Answer 1

Your relation is not really a database relation try to make you're relation like this:
public function up()
{
Schema::create('players', function (Blueprint $table) {
$table->increments('id');
$table->unsignedInteger('club_id');
$table->foreign('club_id')->references('id')->on('clubs');
$table->string('first_name');
$table->string('last_name');
$table->double('price', 3, 2);
$table->enum('position', ['goalkeeper','defender','Midfielder','Striker']);
$table->timestamps();
});
}

Answer 2

Player Model
class Player extends Model
{
public function club()
{
return $this->belongsTo('App\Club', 'club_id', 'id');
}
}
Player controller
public function index()
{
$players=Player::find(1);
echo $players->club->location;
}

Answer 3

it should be like this :
$players=Player::with('club')->find(1);
echo $players->club->location;

Answer 4

Try without () in ->club(),
public function index()
{
$players=Player::find(1);
echo $players->club->location;
}
As the error says, it refers to the "BelongsTo" relationship. i.e. Here ->club() returns the relationship object, not the club object. If you want to get the club object call as $players->club->location; .
