title: Odoo 10 - Duplicate supplier info for a given product_template
body: <p>I have:</p>
  
  <ul>
  <li>a) given product_template_id (i.e. id 100)  and  </li>
  <li>b) a duplicated product_template_id (i.e. id 200) created using copy() method</li>
  </ul>
  
  <p>copy() method copies only product.template model, so suppliers for that specific product are not copied.</p>
  
  <p>I would like to duplicate all suppliers for that model, but now I am wondering which is the <em>right</em> way to do it in Odoo.</p>
  
  <p>If I understood the model properly suppliers prices for a given product are stored in product_supplierinfo table, where each record that points to a given product_tmpl_id specifices a supplier price/qty for a given product_template.</p>
  
  <p><strong>Which would be the way in Odoo to search for all records that point to a given product_tmpl_id (i.e. 100), duplicate them changing product_tmpl_id to the new one (i.e. 200)?</strong></p>
