Hello, in Odoo 8 i created @api.onchange function that sets domain to many2one field if another field is changed. This works OK so far but the problem is if editing existing records.

For example if i have Selection field with options Yes and No and if Yes is selected then Many2one field must allow only ids 1,2,3. If No is selected the Many2one must allow 4,5.

Changing Selection applies the domain to Many2one.

If i edit already saved record having Selection=Yes i see all the values 1,2,3,4,5 in Many2one.

Why onchange and domain is not applied when editing records?

since the beginning, it's not a decent solution to add dynamic domain. there is no communication between server-client when view mode change.
Odoo is removing all the dynamic domain from V14 :)

have to add domain on many2one field with like 

options = fields.Selection(....)
my_m2o_id = fields.Many2one('my.model', domain=[('options',  '=?', options)])

Ah ok, this is an idea. 

I will add another field in my many2one model indicating the current value for which options is allowed and will assign the new fields values a per our needs. Thank you.
