Value error when trying to call a Wizard in Odoo 12

i am using odoo 12, and when trying to call a wizard in an action button it does not works

What is weird is if i use the wizard as a button (just for testing) it works.

Here is my code

This is the action dropdown button

    <!--action dropdown-->
    <record id="action_enviar_a_evaluacion" model="ir.actions.server">
        <field name="name">Enviar a evaluacion</field>
        <field name="model_id" ref="model_pdi_riesgo"/>
        <field name="state">code</field>
        <field name="code">
            pdi_riesgo_wizard_evaluacion.enviar_a_evaluar()
        </field>

        <field name="binding_model_id" ref="model_pdi_riesgo"/>
    </record>

And this is the method i am trying to call

@api.multi
    def enviar_a_evaluar(self,ids):
        r_fase_en_evaluacion=self.env['pdi.riesgo.fase'].search([('sequence','=',2)])
        #self.riesgo.fase_evaluacion=r_fase_en_evaluacion.id
        registros = self.browse(ids)

        for riesgo in registros:
            riesgo.fase_evaluacion=r_fase_en_evaluacion.id
            record=self.env['pdi.riesgo.evaluacion'].sudo().create({
                'riesgo':riesgo.id,
                'fase':r_fase_en_evaluacion.id,
                'comentario':'Se envia a evaluar',
                'fecha_limite':self.fecha_limite
            })

and this is the error i am getting

Error:

'pdi_riesgo_wizard_evaluacion.enviar_a_evaluar()'

Solution

A number of keys are available in the evaluation context of or surrounding server actions:

model: model object linked to the action via model_id
record/records: record/recordset on which the action is triggered, can be void. env Odoo Environment
datetime, dateutil, time, timezone: corresponding Python modules
log: log(message, level='info'): logging function to record debug information in ir.logging table
Warning: constructor for the Warning exception

Try to replace pdi_riesgo_wizard_evaluacion with records in the server action code:

<field name="code">records.enviar_a_evaluar()</field>

And change the signature of the method to:

enviar_a_evaluar(self):

Example:

@api.multi
def enviar_a_evaluar(self):
    r_fase_en_evaluacion = self.env['pdi.riesgo.fase'].search([('sequence', '=', 2)])
    for riesgo in self:
        riesgo.fase_evaluacion = r_fase_en_evaluacion.id
        self.env['pdi.riesgo.evaluacion'].sudo().create({
            'riesgo': riesgo.id,
            'fase': r_fase_en_evaluacion.id,
            'comentario': 'Se envia a evaluar',
            'fecha_limite': riesgo.fecha_limite
        })

You can find an example in the mrp module, It calls the button_plan method using records.
