TLDR: How to refresh a field (one2many Tree) from the custom widget used by it in Odoo13.
I created a widget to make it possible to select lines on a one2many field and call a python function on the selected items. When the user clicks the button defined in the widgets XML template I call python function via RPC from the widget. I would like to achive the following:
Save the main parent (Sale Order) form
I would need this so if the user added any new items to the on2many field I can use and manioulate them in my bulk called python function. Without this I'm getting `record does not exists`
Refresh the parent form (Sale Order)
Refresh one2many field only (tree)
Important: I would like to do this in Odoo13.
Python field definition:
class SaleOrder(models.Model):
_inherit = 'sale.order'
one2many_field = fields.One2many(compute='_compute_one2many_field',
comodel_name='some.other.model',
inverse_name='sale_order_id',
string='One 2 Many Field')
XML field definition:
<field
name="one2many_field"
widget="one2many_selectable"
action="bulk_add"
options="{'some_custom_option)': true}">
<tree>
<field name="field_value_foo"/>
<field name="field_value_bar"/>
</tree>
</field>
