根据Odoo中的产品ID填充下拉列表

Question

我在制造商的产品表格中创建了一个标签。它有manufacturer_name和manufacturer_partno字段以及其他一些字段。每个产品都有多个制造商（一对多关系）。我想在添加供应商表格中获得manufacturer_partno的下拉列表，它们是相同的产品（相同的产品ID）。我只是想知道这是怎么可能的。如果可以，请帮帮我。

    class product_template(osv.osv):
    _inherit = "product.template"
    _columns = {
        'mrpproduct_partnumber': fields.char("Part Number", size=30, required=True),
        'mrpproduct_description': fields.text("Description", required=True),
