What are menu badges in odoo?

Adding menu badges in odoo

You do not need to do anything more than what's shown in the post. You just need toiInheriting from the "mixin" and "defining the method" named "_needaction_domain_get" is all that you need. Odoo will automatically pick it up and display next to all menu items pointing to actions for this particular model. Below are the code snippet, that you just need to copy and paste.

class your_model(models.Model):
    _name = 'your.model'
    _inherit = ['ir.needaction_mixin'] 
 state=fields.Selection([('Draft','Draft'),('Submitted','Submitted'),('Approved','Approved')],'State',default='Draft')

    @api.model
    def _needaction_domain_get(self):
  # getting login user groups
        user_groups = self.env['get.user.groups'].get_groups_function(self.env.user.login)
  
  # Check if "your_desired_group" is in above groups than show numeric values on the menu, for the state "Submitted"
        if set(['your_desired_group']) & set(user_groups):
            return [('state', '=', 'Submitted')]
        else:
            return False      
 

Code Description

To use badges in our menu we just need to inherit "ir.needaction_mixin". After inheriting, just define a method named "_needaction_domain_get" this method will return a domain that selects these states value that should be counted towards the number on the badge. In our case it would be "Submitted".
