I created a simple model x_ovh_phone to follow phone calls (data are pushed by our OVH call center).
Fields are x_date, x_description, x_call_duration and a many2one field to connect to helpdesk.ticket
In helpdesk formview, I used Studio to add a one2many field associated to the many2one of x_ovh_phone
<xpath expr="/form[1]/sheet[1]/group[1]" position="after">
<field name="x_studio_field_9WAxj" mode="tree">
<tree string="Liste des appels">
<field name="x_date"/>
<field name="x_call_direction"/>
<field name="x_studio_field_9Db5i"/>
<field name="x_call_duration_display"/>
</tree>
</field>
</xpath>
</xpath>
I would like to be able to show 'Search more' button instead to be only able to select a phone call fro a ticket.
