Hi,

Try the following code.

from odoo.addons.web.controllers.main import Database, db_list

class restrict_Database(Database):

    def _is_user_admin(self):

        uid=request.session.uid
        cr=request.cr
        context=request.context

        # Admin user allowed
        if uid==SUPERUSER_ID:
            return True

        # Get technical features group
        data_obj=request.registry['ir.model.data']
        admin_group_id=data_obj.search(cr, SUPERUSER_ID, [('model','=','res.groups' ),('name','=','group_no_one')], context=context)
        if admin_group_id:

                # Check if user belongs to group technical features
                groups_obj=request.registry['res.groups']
                user_id=groups_obj.search(cr, SUPERUSER_ID, [('id','=',admin_group_id[0]), ('users','in', [uid])], context=context)

                return user_id and True or False


        return False

# sample for the manager route, we can create the route for the create, delete, and all other manager options


 @http.route('/web/database/manager', type='http', auth="none")
    def manager(self, **kw):

        # Check if admin group
        if self._is_user_admin():
            # If admin group, call parent class method
            return super(restrict_Database, self).manager(**kw)

        # If not admin group, error page
        else:
            return  env.get_template("template_value").render({'conditions})
