Hello,

Try this

from odoo import models, fields, api
from odoo.exceptions import ValidationError

class MyClass(models.Model):
_name = 'my.class'
name = fields.Char('Name')

@api.model
def create(self, vals):
if not self.name:
raise ValidationError("Write your message ")
return super(MyClass, self).create(vals)


@api.model
def write(self, vals):
if not self.name:
raise ValidationError("Write your message ")
return super(MyClass, self).create(vals)





In the provided code, if we want the message after creating a record and then save use the create method, and if we want the message after editing the created record we can use the write method

1. Create a new module or identify the existing module where you want to add the customization.

2. Inside your module, create a new JavaScript file, let's call it custom_script.js, and add your custom JavaScript code in it. For example:

odoo.define('your_module.custom_script', function (require) {
"use strict";

var FormController = require('web.FormController');
var core = require('web.core');
var Dialog = require('web.Dialog');

FormController.include({
_saveRecord: function () {
var self = this;
var confirmMessage = "Are you sure you want to save?"; # Custom confirmation message

Dialog.confirm(this, confirmMessage, {
confirm_callback: function () {
self._super.apply(self, arguments);
},
cancel_callback: function () {
#Perform actions when the user cancels the save action
# ...
},
});
},
});
});

In the above code, we define a new JavaScript module named your_module.custom_script. We include the necessary dependencies web.FormController, web.core, and web.Dialog. We extend the FormController and override the _saveRecord method, which is responsible for handling the Save action.

Inside the overridden method, we create a confirmation dialog using web.Dialog.confirm(). The confirm_callback function is executed when the user confirms the save action, and the default save behavior is invoked. The cancel_callback function is executed when the user cancels the save action, allowing you to perform any additional actions if needed.
