Compute field not working when using Store attribute.

Question

@api.depends("product_tmpl_id")
def _computeBOMLine(self):
for record in self:
bom_lines = record.product_tmpl_id.bom_ids.mapped("bom_line_ids").filtered(lambda x: record.id in x.bom_product_template_attribute_value_ids.ids)
if any(bom_lines):
record.computed_bom_line_id = bom_lines[0].id
else:
record.computed_bom_line_id = False

computed_bom_line_id = fields.Many2one("mrp.bom.line",compute="_computeBOMLine", store=True)

Compute method is not getting called, unless I remove store attribute not

Hi,
If you have a compute field in your model and if you give store=True for
the field, the field value will not get recomputed if proper depends is
not given for the compute function. As the compute function is not
getting recomputed you will have wrong value in the field.
See:-  Why Stored Computed Fields Are Not Recomputing in Odoo [1]

Thanks

Hi,
yes It was related to store=True. I had to remove it since I couldn't figure out any other hook point to trigger it.

Thanks for the response.

Sunil
