I use odoo 10 and I created a custom module to plan trips. I create a view for the plans in which I will select the list of my travels. My problem now is how I can get the Start and Destination fields of each trip insert in this view knowing that the field that displays the list of trips is travel_ids = fields.Many2many ('tms.travel', copy = False, string = 'Travels'). I try a lot but no result. Any idea for help please ??

Ok, you are missing some information in your many2many relationship. here is what you need.

field_name = fields.Manmy2many('related.model', 'relational_table', 'current_model_id', 'related_model_id', string='other information')

and usually I put the inverse on the related model ex:

(On the hr.holidays model)

payslip_ids = fields.Many2many('hr.payslip', 'hr_payslip_holiday_rel', 'holiday_id', 'payslip_id', ...)

(On the hr.payslip model)

holiday_ids - fields.Many2many('hr.holidays', 'hr_payslip_holiday_rel', 'payslip_id', 'holiday_id', ...)

Then at some point you need to add one of the ids to the other model for ex:

holiday.payslip_ids |= current_payslip_id
