Prevent record creation in computed One2Many or Mayn2Many in Tree/Kanban field

Question

Hi,
I created a computed Many2Many field. To make it writable, I used the inverted argument to define a reverse function like so:
document_ids = fields.Many2many(..., compute='_compute_document_ids', inverse='_set_document_ids')
def _compute_document_ids(self):

def _set_document_ids(self):

Now I want to have the Kanban *not to be abl

Create a separate form view for editing the records and use it when clicking on a record in the

Hi. Thanks for your answer.
According to it I created another view for editing the detail data (in my case Document). Odoo also uses this view correctly to display the detail date and I am also able to edit the record with this view.
But as soon as I make the Many2Many / One2Many field *readonly* in the parent view then the detail data view is also *locked* so that I cannot edit data anymore.
The same result also if I replace the Kanbank Many2Many with a tree.
