title: Odoo API with Ripcord library: how to post language parameter
body: <p>I'm working on connecting Magento with Odoo.  I run this call:</p>
  
  <pre><code>$records = $models-&gt;execute_kw($db, $uid, $pass, 'product.product', 'read', array(array(2))
                          , array('fields' =&gt; array(
                          'id',
                          'active',
                          'categ_id',
                          'display_name',
                          'description',
                          'image',
                          '__last_update',
                          'list_price',
                          'qty_available',
                          'taxes_id',
                          'write_date',
                          'promotion_note',
                          'publish_website'
                      ),
  
                          )
                  );
  </code></pre>
  
  <p>But how does the language parameter fit in? For the display_name and description I want the nl_BE translation. I was thinking of fitting</p>
  
  <pre><code>array("lang"=&gt;"nl_BE") 
  </code></pre>
  
  <p>in as argument but I get a</p>
  
  <pre><code>TypeError: execute_kw() takes at most 6 arguments (7 given)
  </code></pre>
  
  <p>error... .  Anyone who has dealt with the same issue?</p>
