Get Settings with id of 1? Laravel5.4* - laravel

Question

I have the following tables:
Uses table:
Schema::create('users', function (Blueprint $table) {
$table->increments('id');
$table->string('firstname');
$table->string('surename');
$table->string('address')->nullable();
$table->string('city')->nullable();
$table->string('country')->nullable();
$table->string('postcode')->nullable();
$table->string('email')->unique();
$table->string('password');
$table->rememberToken();
$table->string('facebook_id')->nullable();
$table->string('linkedin_id')->nullable();
$table->string('twitter_id')->nullable();
$table->timestamps();
});
Setting table:
Schema::create('settings', function (Blueprint $table) {
$table->increments('id');
$table->string('value');
$table->timestamps();
});
Setting_user (Pivot table):
Schema::create('setting_user', function (Blueprint $table) {
$table->integer('user_id')->unsigned();
$table->foreign('user_id')->references('id')->on('users');
$table->integer('setting_id')->unsigned();
$table->foreign('setting_id')->references('id')->on('settings');
$table->timestamps();
});
Categories table:
Schema::create('categories', function (Blueprint $table) {
$table->increments('id');
$table->string('name');
$table->timestamps();
});
Setting_category (pivot table):
Schema::create('setting_category', function (Blueprint $table) {
$table->integer('category_id')->unsigned();
$table->foreign('category_id')->references('id')->on('categories');
$table->integer('setting_id')->unsigned();
$table->foreign('setting_id')->references('id')->on('settings');
$table->timestamps();
});
In my User model this I have a belongsToMany relationship:
public function settings()
{
return $this->belongsToMany(Setting::class, 'setting_user', 'user_id','setting_id')->with('category');
}
And in my setting model:
protected $table = 'settings';
public function category()
{
return $this->hasMany(Categories::class,'id');
}
When I access it like so:
public function settings()
{
$user = User::find(1);
return $user->settings()->with('category')->first();
}
This is the result I get:
{"id":1,"value":"87658675.jpg","created_at":"2017-07-04 00:00:00","updated_at":null,"pivot":{"user_id":1,"setting_id":1},"category":[{"id":1,"name":"avatar","created_at":"2017-07-06 00:00:00","updated_at":null}]}
How can I get only the settings with category->id == 1 ?
Many thanks

Answer 1

If you want to get only settings for specified user and specified category, use whereHas():
public function settings()
{
$categoryId = 1;
$userId = 1;
return Settings::whereHas('categories', function ($q) use ($categoryId) {
$q->where('id', $categoryId);
})
->whereHas('users', function ($q) use ($userId) {
$q->where('id', $userId);
})
->get();
}
To make this work, fix your relationships. Looks like all relations should be belongsToMany() and not hasMany()

Answer 2

I have changed the relationships in my Setting model to:
public function users()
{
return $this->belongsToMany(User::class, 'setting_user','setting_id', 'user_id');
}
public function categories()
{
return $this->belongsToMany(Categories::class,'setting_category','category_id','setting_id');
}
I still have the belongsToMany relationship in my User model :
public function settings()
{
return $this->belongsToMany(Setting::class, 'setting_user', 'user_id','setting_id');
}
And I have created another method to extract the Avatar which has id of "1" like so :
/**
* Get user's avatar.
*/
public function getAvatarAttribute() {
$categoryId = 1;
$userId = Auth::user()->id;
$avatar = $this->settings()->whereHas('categories', function ($q) use ($categoryId) {
$q->where('id', $categoryId);
})->whereHas('users', function ($q) use ($userId) {
$q->where('id', $userId);
})->first();
if(!$avatar)
{
return "default-avatar.jpg";
}
return $avatar->value;
}
