title: Where is the list of the types of exceptions?
body: <p>Please help me find the official documentation with a list of the types of  of exceptions. I wrote this action:</p>
  
  <pre><code>def show
    begin
      @user = User.find(params[:id])   
    rescue ActiveRecord::RecordNotFound =&gt; e
      logger.debug e
      logger.debug "Error #{$!}"
      render_404      
    end
  end
  </code></pre>
  
  <p>I need to mention several types of exceptions:</p>
  
  <pre><code>def show
    begin
      @user = User.find(params[:id])   
    rescue ActiveRecord::RecordNotFound =&gt; e
      logger.debug e
      logger.debug "Error #{$!}"
      render_404  
    rescue anotherExceptionType1 =&gt; e   
      ......
      ......
      ..... 
    rescue anotherExceptionType2 =&gt; e   
      ......
      ......
      ..... 
    rescue anotherExceptionType3 =&gt; e   
      ......
      ......
      .....         
    end
  end
  </code></pre>
  
  <p>but I did not find the list of exceptions in the documentation.</p>
