hello into python you can do like

def leave_filter_act(self):
    action = self.env.ref('module_name.action_server_leave_filter').read()[0]   
    return action

if you used the ir.actions.server if the user press back then forward from the browser the filter will be removed

Hi, I have slightly similar case. I am trying to call a method that calls a google maps report produced in python because with qweb was too difficult. 

<record id="action_map_report" model="ir.actions.server">
    <field name="name">Reporte Google Maps</field>
    <field name="condition">True</field>
    <field name="type">ir.actions.server</field>
    <field name="model_id" ref="model_operaciones_servicios"/>
    <field name="state">code</field>
    <field name="code">action=self.generar_reporte_gmaps_servicios(cr,uid,context.get('active_ids'), context=context)</field>
 </record>

<record model="ir.values" id="ir_operaciones_servicios_map_report">
    <field name="key2">client_action_multi</field>
    <field name="name">Analisis Recorrido en Google Maps</field>
    <field name="value" eval="'ir.actions.act_window,' + str(ref('operaciones.action_map_report'))" />
    <field name="key">action</field>
    <field name="model">operaciones.servicios</field>
 </record>

Here is the method that I am calling that is in the operaciones.servicios class:

@api.model
def generar_reporte_gmaps_servicios(self):
    fecha1 = self.fecha_reporte[:8] + '01'
    return {
        "type": "ir.actions.act_url",
        "url": "/web/operaciones/gmaps/servicios?ids=%s" % (self.ids),
        "target": "self",
        }

When a load the operaciones.servicios form returns this error:

When I delete the actions the form loads OK. What is wrong please?
