Laravel belongsTo relationship returning null?












-1















I'm trying to fetch matches that are scheduled for today, but it seems my relationships aren't working and returning null.



How I fetch todays matches:



$scheduledMatches = ClanMatch::whereDate('created_at', Carbon::today())->get(); 
// ->count() of the above line is 0 if I add 'has('homeClan', 'awayClan')'


What's returning null exactly?



$firstMatch = $scheduledMatches->first();
dd($firstMatch->homeTeam); // returns null


Also, when trying to foreach $scheduledMatches it throws the null error when accessing fields that I'm trying to access fields on something that is null (a record in $scheduledMatches).



How do I know that it's actually not null?



$firstMatch = $scheduledMatches->first();
$clan = Clan::find($firstMatch->home_team); // exists


Here is the ClanMatch model:



class ClanMatch extends Model
{
protected $table = 'clan_matches';

public function homeTeam() {
return $this->belongsTo('AppClan', 'home_clan');
}

public function awayTeam() {
return $this->belongsTo('AppClan', 'away_clan');
}
}


Clan model as requested



<?php

namespace App;

use IlluminateDatabaseEloquentModel;
use AppClanMatches;

class Clan extends Model
{
public function homeMatches() {
return $this->hasMany('AppClanMatch', 'home_clan');
}

public function awayMatches() {
return $this->hasMany('AppClanMatch', 'away_clan');
}

public function matches() {
return ClanMatch::where('home_clan', $this->id)->orWhere('away_clan',$this->id);
}

public function points() {
return ($this->matchesWon()->count() * 3) + $this->matchesDrawn()->count();
}

public function seasons()
{
return $this->belongsToMany(Season::class);
}

public function tournaments() {
return $this->belongsToMany(Tournament::class);
}
}


Migrations (table strucuture)



// clans table
Schema::create('clans', function (Blueprint $table) {
$table->increments('id');
$table->string('name');
$table->string('tag');
$table->string('logo');
});

// clan matches table
Schema::create('clan_matches', function (Blueprint $table) {
$table->increments('id');
$table->integer('tournament_id');
$table->integer('home_clan');
$table->integer('home_score');

$table->integer('map');
$table->enum('participants', [4,5,6]);
$table->timestamp('scheduled_for');
$table->timestamps();
});

  • Its 0 if I add has('homeClan', 'awayClan'), 1 if I don't add the has('homeClan', 'awayClan').

some debugging tips:



make sure your migrations are like this



clan_matches
$table->increments('id');

clans
$table->unsignedInteger('home_team')->nullable();
$table->unsignedInteger('away_team')->nullable();
$table->foreign('home_team')->references('id')->on('clan_matches');
$table->foreign('away_team')->references('id')->on('clan_matches');


now make sure your tables has some data like



clan_matches
id|name|
1|home
2|away

clans
id|name|home_team|away_team
1|home|1|null
2|away|2|null


now this should return you results

    you can print this code:



    ClanMatch::with('homeTeam', 'awayTeam')
    ->whereDate('created_at', Carbon::today())
    ->toSql();


    and check the result in phpmyadmin or other database program.

    • The data definitely exists, as its returning something. It's just the relationships that link it with the clan's table are returning null. I think this answer would be better as a comment also, but many thanks for your suggestion.
