title: Model X is not associated with Model Y cakephp
body: <p>I have Image which belongsTo User, and I have Coupon which belongsTo User.  Each of the images and coupons table have a foreignKey of 'user_id' in my db.  When I debug the output of this controller logic:</p>
  
  <pre><code>$f=$this-&gt;Coupon-&gt;find('all', array(
  
              'conditions'=&gt;array(
                  'OR'=&gt; array (
                      'Coupon.expires' =&gt;0,
                      'Coupon.end_date &gt;'=&gt;date('y-m-d')
                      )
                  ),
              'contain'=&gt;array(
                  'Image',
                  'Location'=&gt;array('id','address','city','state','zip','area_code','exchange','sln','website'),
                  'User'=&gt;array('id')
                  )
              )
  
         );
        $this-&gt;set('printcoupons', $f);
        }
  </code></pre>
  
  <p>I get all of my data except an Image array, which cake tells me is not associated with Coupon.  I have tried setting the recursiveness of Coupon to 2, and I get no change in what gets retrieved.  I tried loading the User model and doing a find that way, with disastrous results.  I just don't understand how better to get Image and Coupon to play together, considering I don't want them directly associated with each other.</p>
