mailing.mailing.form.email.templates
mailing.mailing











my module.py content is:

from odoo import models, fields, api


class EmailTemplates(models.Model):
   _inherit = 'mailing.mailing'
   _description = 'extension of the email marketing add custom email templates '

   email_template = fields.Html(string="TEST-22")



And my xml content is:



   
       
            Email template
            my_module.my_module
           
           
                 
                     
                         
                     
               
             
       
   




Also I'm trying to add a widget to show my email's templates but I don't know how to define the paths of my templates, drafts, sending and sents emails to show in it or if I should use a custom widget for this, and I tried to create a new module to modificate it with my module butthis got me the same error
