Hi, I have a model of incidents with this field:-

team_ids = fields.Many2many( 'moderation.team', relation='incident_incident_moderation_team_rel', string='Moderation Teams',        column1='incident_incident_ids', column2='moderation_team_ids', ondelete='restrict',  required=True)​

And each logged in user will have a field called 'team_ids' that contains the teams that they are assigned to. 

team_ids = fields.Many2many('moderation.team', relation='res_users_moderation_team_rel',         column1='res_user_ids', column2='moderation_team_ids')

Now I want to create a record rule in the security.xml that will allow only those users who have in their 'user.team_ids' field, at least one of the team_ids that has been assigned to the incident record. 

I've tried a few things but my problem is that I don't understand the structure of these data types and I'm struggling. How do I write this record rule?
