Hi Miadi,

You want to call the python function when clicking the menu or when opening the form ?

If you want to call python function on clicking the menu, You can check this link, here it is a server action from the menu item.

If you want to call python function on loading a form view, you can give compute function to any of the field in the view. Compute function will get called once the view is called.

class RespartnerExtend(models.Model):
    _inherit = 'res.partner'

    sample_field = fields.Char(string="User", compute='call_function')
 
    @api.depends('sample_field')
    def call_function(self):
        #write the function body here

Hi Niyas,

I tried that I've found in your link. I've made this but it's gives me this error : ParseError:
"External ID not found in the system: miadi_packaging.miadi_poidsConditionnement" while parsing file:///C:/Program Files (x86)/Odoo 10.0/server/odoo/addons/miadi_packaging/views/miadi_poidsConditionnement_view.xml:62, near

<record id="action_chargement_ratio" model="ir.actions.server">
			<field name="name">Chargement Ratio</field>
                        <field name="type">ir.actions.server</field>
			<field name="model_id" ref="model_miadi_PC"/>
                        <field name="code">action = self.chargement_ratio()</field>
		</record>

There is my miadi_poidsConditionnement.py :

import odoo from odoo import models, fields, tools, api

class miadi_poidsConditionnement(models.Model):

    _name = 'miadi.poidsconditionnement' 

    conditionnement_id = fields.Char('Packaging', size=4, default='', required=True) 

    produit_id = fields.Char('Product', size=256, default='')

    nb_articles = fields.Integer(string='Number of products', default=0)

    poids = fields.Float(string='Packaging Weight', default=0)

    _sql_constraints = [

        ('uniq_id', 'unique(produit_id, conditionnement_id)', 'A product already exists with this packaging !'),

     @api.multi

    def chargement_ratio(self):

            conditionnements = self._cr.execute("SELECT conditionnement_id FROM miadi_packaging")

            productRatio = self.env['miadi.poidsconditionnement']

            products = self.env['product.product'].search([])

            for conditionnements in self.env.cr.dictfetchall():

                    nom_conditionnement = conditionnements['name']

                    for rec in products:

                            product = rec.display_name

                            productRatio.create({'conditionnement_id': nom_conditionnement, 'produit_id': product})

And my XML file where are the views of the menuitem on which I want to do the action (miadi_poidsConditionnement_view.xml) :
