编写一个从表中复制数据的按钮(Python3、Odoo 14)

Question

我试图编写一个复制函数，将数据从表复制到同一个表。

def formmst_copy_func(self):
_logger.info('=== formmst_copy_func start ===')
for record in self:
formbas_obj = self.env['hre.formmst']
defaults = {
'form_no': record.form_no,
'hre_orgbas_id': record.hre_orgbas_id.id if record.hre_orgbas_id else False,
'form_name': record.hre_formmst_id.form_name,
'form_type': record.hre_formmst_id.form_type,
'calculate_type': record.hre_formmst_id.calculate_type,
'total_score': record.hre_formmst_id.total_score,
'hre_formdtl_ids': record.hre_formmst_id.hre_formdtl_ids,
}
formbas_obj.create(defaults)
_logger.info('=== formmst_copy_func end ===')

hre_formmst_id是Many2one字段。hre_formdtl_ids是一个2任意字段。

使用按钮调用此函数。

<record id="form_hre_formbas_copy_wizard" model="ir.ui.view">
<field name="name">form.hre.formbas.copy.wizard</field>
<field name="model">hre.formbas.copy.wizard</field>
<field name="arch" type="xml">
<form>
<group col="4">
<field name="hre_formmst_id"/>
<newline/>
<field name="form_no"/>
<field name="hre_orgbas_id"/>
</group>
<footer>
<button string="Copy" name="formmst_copy_func" type="object" class="oe_highlight"/>
or
<button string="Cancel" special="cancel" type="object" class="oe_link"/>
</footer>
</form>
</field>
</record>

该功能可以成功复制数据
但是原始数据中的hre_formdtl_ids消失了
如何修复该功能？请给我一些建议。谢谢

Answer 1

尝试将one2many字段更新为[(6，0，id(]或[(4，id(]

用于填充多个和一个：

(0, 0,  { values })    link to a new record that needs to be created with the given values dictionary
(1, ID, { values })    update the linked record with id = ID (write *values* on it)
(2, ID)                remove and delete the linked record with id = ID (calls unlink on ID, that will delete the object completely, and the link to it as well)
(3, ID)                cut the link to the linked record with id = ID (delete the relationship between the two objects but does not delete the target object itself)
(4, ID)                link to existing record with id = ID (adds a relationship)
(5)                    unlink all (like using (3,ID) for all linked records)
(6, 0, [IDs])          replace the list of linked IDs (like using (5) then (4,ID) for each ID in the list of IDs)

因此，在您的情况下，您可以尝试：

def formmst_copy_func(self):
_logger.info('=== formmst_copy_func start ===')
for record in self:
formbas_obj = self.env['hre.formmst']
defaults = {
'form_no': record.form_no,
'hre_orgbas_id': record.hre_orgbas_id.id if record.hre_orgbas_id else False,
'form_name': record.hre_formmst_id.form_name,
'form_type': record.hre_formmst_id.form_type,
'calculate_type': record.hre_formmst_id.calculate_type,
'total_score': record.hre_formmst_id.total_score,
'hre_formdtl_ids': [(4, l.id for l in record.hre_formmst_id.hre_formdtl_ids)],
}
formbas_obj.create(defaults)
_logger.info('=== formmst_copy_func end ===')
