title: CakePHP Form action from other controller
body: <p>Well, I have a CakePHP 2.2.5 app which is basically management of users, and a user has a photo, and I create a PhotosController (as suggestion of this <a href="http://goo.gl/oglQn" rel="nofollow">tutorial</a>). I tested it and it works perfectly on <code>Photos/View</code>, including the ajax elements to be possible send a photo in a form without redirecting. And now I'm trying to connect all of this, but it ins't as easy as I think it should be.</p>
  
  <p>My Photo add method:</p>
  
  <pre><code>public function add()
  {
      if ( $this-&gt;request-&gt;is( 'post' ) ) {           
          $this-&gt;Photo-&gt;create();
          $json = array( 'result' =&gt; array( 'files' =&gt; array() ) );
          if ( $this-&gt;Photo-&gt;save( $this-&gt;request-&gt;data ) ) {
              $photo                             = $this-&gt;Photo-&gt;findById( $this-&gt;Photo-&gt;id );
              $json['files'][0]['name']          = $photo['Photo']['basename'];
              $json['files'][0]['size']          = $this-&gt;request-&gt;data['Photo']['file']['size'];
              $json['files'][0]['url']           = $this-&gt;webroot . 'media/transfer/img/' . $photo['Photo']['basename'];
              $json['files'][0]['thumbnail_url'] = $this-&gt;webroot . 'media/filter/thumbnail/img/' . $photo['Photo']['basename'];
          }
          else {
              $json = 'Error';
              $this-&gt;Session-&gt;setFlash( __( 'The photo could not be saved. Please, try again.' ) );
          }
          $this-&gt;RequestHandler-&gt;renderAs( $this , 'ajax' );
          Configure::write( 'debug' , 0 );
          $this-&gt;set( 'json' , json_encode( $json ) );
          $this-&gt;render( '/Elements/ajax' );
      }
  </code></pre>
  
  <p>My test View (on users controller):    </p>
  
  <pre><code>&lt;?php echo $this-&gt;Form-&gt;create(
          'Photo' ,
          array( 'url'     =&gt; array( 'controller' =&gt; 'photos' ,
                                     'action'     =&gt; 'add'
          ) ,
                 'id'      =&gt; 'fileupload' ,
                 'enctype' =&gt; 'multipart/form-data'
          )
      ); ?&gt;
  &lt;-- Some HTML HERE--&gt;
  &lt;?php
                  echo $this-&gt;TB-&gt;input(
                      'Photo.file' ,
                      array(
                          'prepend' =&gt; 'Upload' ,
                          'type'    =&gt; 'file' ,
                          'class'   =&gt; 'fileUpload' ,
                          //'multiple' =&gt; 'multiple',
                          'div'     =&gt; FALSE ,
                          'between' =&gt; FALSE ,
                          'after'   =&gt; FALSE ,
                          'label'   =&gt; FALSE ,
                          'help'    =&gt; NULL ,
                      )
                  );
                  ?&gt;
  &lt;/form&gt;
  &lt;-- Some (already tested) Javascript to make this work HERE--&gt;
  </code></pre>
  
  <p>The view renders without php errors, but when I upload a file I get an Javascript error, and the debug says:</p>
  
  <pre><code>GET http://&lt;server&gt;/&lt;app&gt;/users/add 404 (Not Found) jquery.min.js:1960
    send jquery.min.js:1960
    b.extend.ajax jquery.min.js:1840
    (anonymous function) main.js:59
    c jquery.min.js:215
    p.fireWith jquery.min.js:249
    b.extend.ready jquery.min.js:69
    H jquery.min.js:10
  </code></pre>
  
  <p>Actually, I get this error on both, GET and POST methods (with some different line of jQuery of course).</p>
  
  <p>Even the action is set to the PhotosController it is trying to access the Users. I think because of the view, as I din't specify users anywhere. I am trying to solve this problem for a week and I don't have more ideas.
  Any help would be greatly appreciated. </p>
  
  <p>Thanks in advance.</p>
