title: How should I select only data related to logged user?
body: <p>I have class where I inject AppDbContext</p>
  <pre><code>private readonly AppDbContext context;
  
      public SQLExpenseRepository(AppDbContext context)
      {
          this.context = context;
      }
  </code></pre>
  <p>I added identity system to my website and now I need to change data so only data related to current logged user will be passed.
  This context has context.Categories and I would like to choose only those where user matches with current logged. Is there a way to do this from this constructor or I have to add .Where(...) in every method?</p>
