title: BelongsTo in Laravel
body: <p>I have a table which is named <strong>cars</strong> with 2 fields <code>id, matriculation</code>. 
  Then, I have another table which is named <strong>series</strong> with 2 fields <code>id, name</code>.</p>
  
  <p>I have created my <code>fk_serie</code> on my table <strong>cars</strong>.</p>
  
  <pre><code>public function up()
      {
          Schema::create('cars', function (Blueprint $table) {
              $table-&gt;increments('id');
              $table-&gt;string('matriculation', 25);
              $table-&gt;integer('fk_serie')-&gt;unsigned();
              $table-&gt;foreign('fk_serie')-&gt;references('id_serie')-&gt;on('serie');
              $table-&gt;timestamps();
          });
      }
  </code></pre>
  
  <p>Here is my information about the table <strong>series</strong>.</p>
  
  <pre><code>public function up()
      {
          Schema::create('series', function (Blueprint $table) {
              $table-&gt;increments('id');
              $table-&gt;string('name', 30);
              $table-&gt;timestamps();
          });
      }
  </code></pre>
  
  <p>In my model, I only have a function on the model <strong>Car</strong>.</p>
  
  <pre><code>public function serie(){
      return $this-&gt;belongsTo('App\Serie', 'fk_serie');
  }
  </code></pre>
  
  <p>I don't have nothing in my model <strong>Serie</strong></p>
  
  <pre><code>class Serie extends Model
  {
      //
  }
  </code></pre>
  
  <p>Is it normal that the model <strong>Serie</strong> is empty? 
  Because, my join works.</p>
  
  <p>What do you think ?</p>
