title: What is the best way to implement belongs to many logic in Rails?
body: <p>For example I have model Match and model Player. What I want is for Player to be able to participate in many matches.</p>
  <p>So it should look smth like this:</p>
  <pre><code>@match_first = Match.first
  @match_last  = Match.last
  
  @match_first.players
  #player1, player3, player4
  @match_last.players
  #player1, player4, player5
  </code></pre>
  <p>Both matches can have same players simultanously.</p>
