[web2py] display fill text in a {{ row }} not the trucate one

[bussiere adrien]

I have this when i put a {{row}} in a template (liste_invitations) :
{{extend 'layout.html'}}
<h1>Records</h1>
{{=rows}}

it gives me :

Invitation.id Invitation.Code Invitation.Usage Invitation.Donneur 
Invitation.Receveur Invitation.Email Invitation.Used
1 Toto-5542 None None None None None
2 USER_INTERFAC... None None None None None

USER_INTERFAC...  is truncated how to have it in full ?

here is the the controller :
def liste_invitations():
    return dict(rows = db().select(db.Invitation.ALL))

it truncate the text of the invitation
