title: Check if a user has a specific object with quick.db
body: <p>Hello I am trying to check if someone has an object in his inventory witch quick.db
  But when I try, whatever the artist is it always says that it's the inventory of the user. Here's the code that I use.</p>
  <pre class="lang-js prettyprint-override"><code>const db = require('quick.db');
  let discord = require('discord.js');
  
  module.exports = {
      name : 'test',
      description : &quot;commande test&quot;,
      async execute(message, args) {
  
          const artist = message.content.slice(7).trim();
  
          if(!artist){
              message.channel.send(&quot;Spécifier l'artiste&quot;)
          }
  
  
  
          if(db.has(message.author.id, artist)){
              message.channel.send(&quot;Artiste Present&quot;)
          }
          else{
              message.channel.send(&quot;Non présent&quot;)
          }
  
  
      }
  
  }
  </code></pre>
  <p>I use this to add information to the database</p>
  <pre class="lang-js prettyprint-override"><code>if (reaction.count == 2){
     db.push(user.id, name_artist);
  </code></pre>
