To make Odoo 13 Forums send an email notification to all users (e.g., employees) whenever a new forum post is created, you need to configure automated actions or use Odoo’s built-in email notification system. Below are the steps to achieve this:

1. Enable Notifications for Forum Posts

By default, Odoo Forums allow followers of a forum or specific posts to receive notifications. To ensure all employees are notified:

1. Add All Employees as Followers:
   • Navigate to the forum you want to track:
     • Go to Website > Forums and open the specific forum.
   • Click on the Follow button and manually add all employees as followers.

   Tip: Ensure all employees have access to their Odoo accounts and valid email addresses.

2. Default Followers on Forum Creation (Optional):
   • Use Odoo Studio or development tools to make employees follow newly created posts automatically.

2. Use Automated Actions

To send an email notification to all employees when a new post is created, you can create a custom Automated Action.

Steps to Configure Automated Action:

1. Activate Developer Mode:
   • Go to Settings > Activate Developer Mode.
2. Create the Automated Action:
   • Navigate to Settings > Technical > Automation > Automated Actions.
   • Click Create and configure as follows:
     • Model: Forum Post (forum.post).
     • Trigger: On Creation.
     • Action To Do: Send Email.
3. Configure Email Template:
   • In the same automated action, set up an email:
     • Recipients:
       • Select All Employees.
       • Alternatively, you can create a mailing list of employees.
     • Email Template:
       • Create a new email template to format the message with details about the forum post.
       • Example template:

         <p>Hello,</p>
         <p>A new forum post has been created:</p>
         <ul>
           <li>Title: ${object.name}</li>
           <li>Author: ${object.create_uid.name}</li>
           <li>Link: <a href="${object.website_url}">${object.website_url}</a></li>
         </ul>
         <p>Best regards,<br/>Odoo Forums</p>
         

4. Test the Automated Action:
   • Create a new forum post and check if the email notification is sent successfully.

3. Enable Mailing via Odoo Studio

If you’re using Odoo Studio, you can directly add the email-sending logic without needing to write Python code.

Steps:

1. Open the Forum module in Studio.
2. Add a server action to the forum.post model:
   • Trigger: On Creation.
   • Action: Send Email.
3. Use the template you created earlier to notify all employees.

4. Custom Python Code (Optional)

If you want more control, you can create a custom module to handle email notifications for forum posts.

Example Code:

from odoo import models, api

class ForumPost(models.Model):
    _inherit = 'forum.post'

    @api.model
    create(vals):
        # Call the original create method
        post = super(ForumPost, self).create(vals)

        # Notify employees
        employees = self.env['res.users'].search([('groups_id', 'in', self.env.ref('base.group_user').id)])
        for employee in employees:
            template = self.env.ref('module_name.new_forum_post_email_template')
            self.env['mail.template'].browse(template.id).send_mail(post.id, email_values={'recipient_ids': [(4, employee.partner_id.id)]})
        
        return post

• Replace module_name.new_forum_post_email_template with the XML ID of your email template.
• Place the code in a custom module, and ensure the module is installed.

5. Additional Tips

• Unsubscribe Option:
  • If you notify all employees, provide a way for users to unsubscribe from notifications. Add a link in the email to manage subscriptions.
• Performance Optimization:
  • For large organizations, sending emails to many users might slow down the system. Consider batching or using a queue.
• Email Delivery Logs:
  • Navigate to Settings > Technical > Emails > Emails to check if emails are sent successfully.

By using these methods, you can ensure that all employees receive notifications whenever a new forum post is created. Let me know if you need further assistance or detailed guidance on implementing these steps!
