Hi,

for example a teacher wants to display in dashboard courses which it is responsible.

Example create dashboards:

<record model="ir.actions.act_window" id="act_my_courses_tree">
            <field name="name">My Course Tree</field>
            <field name="res_model">openacademy.course</field>
            <field name="view_type">form</field>
            <field name="view_mode">tree,form</field>
            <field name="domain">[('responsible_id','=','uid')]</field>
</record>


   <record model="ir.ui.view" id="board_openacademy_form">
            <field name="name">OpenAcademy Dashboard Form</field>
            <field name="model">board.board</field>
            <field name="type">form</field>
            <field name="arch" type="xml">
                <form string="OpenAcademy Dashboard">
                    <hpaned>
                        <child1>
                            <action string="My Courses" name="%(act_my_courses_tree)d"
                                colspan="2" />                          
                        </child1>
                    </hpaned>
                </form>
            </field>
        </record>

<record model="ir.actions.act_window" id="openacademy_board">
            <field name="name">OpenAcademy Dashboard</field>
            <field name="res_model">board.board</field>
            <field name="view_type">form</field>
            <field name="view_mode">form</field>
            <field name="usage">menu</field>
            <field name="view_id" ref="board_openacademy_form" />
        </record>

<menuitem id="openacademy_menu" name="OpenAcademy"
            action="openacademy_board" />
