I am having a field username = fields.Many2one('res.partner', String="username")in model1.

  Now i am trying to print a report for model 2.  I need to print the value in this field

now i am able to access  this model1 and print it  but when i am printing as

<t t-foreach="doc.member_name" t-as="o">      <!--to access model1 which is user.info -->
                             <tr>
                                 <td><t t-esc="o.username"/></td>
                                 <td><t t-esc="o.email"/></td>

                             </tr>
                         </t>

in my report i got email field as required but for username i am getting like  res.partner(60,)

Is there any way i could get actual username.
