I have added a field document to the project.project model and field attach_compulsory to project.config.settings model and extended the method called by the Create button on the project wizard view to make sure that a document is attached if the attach_compulsory field is selected in the Project settings. However, when i click on the attach_compulsory field in the settings, the button doesn't respond. Here are my codes: # -*- coding: utf-8 -*- from odoo import models, fields, api, _ from odoo.exceptions import UserError import logging from odoo.exceptions import Warning _logger = logging.getLogger(__name__) # Need for message in console. class ProjectWorkflow(models.Model): _inherit = "project.project" state = fields.Selection([ ('draft', 'In Progress'), ('cancelled', 'Cancelled'), ('pending', 'Pending'), ('closed', 'Closed'), ],string='State', readonly=True, default='draft', track_visibility='onchange' ) document = fields.Binary('Project Start File') @api.one def close_project(self): self.state="closed" @api.one def cancel_project(self): self.state = "cancelled" @api.one def pending_project(self): self.state="pending" @api.multi def close_dialog(self): print "=====================Check here=========================" config_set = self.env['project.config.settings'] if config_set.fields_get().get('attach_compulsory', None) is not None: if not self.document: raise UserError("Please attach a project commencement document!") return super(ProjectWorkflow, self).close_dialog() class ProjectConfig(models.TransientModel): _inherit = 'project.config.settings' attach_compulsory = fields.Boolean ('Project Start Document Compulsory', default=False) Here is the xml file: Project Workflow View project.project
