How can I migrate a custom submenu with ir.actions.server from Odoo9 to Odoo12? - migration

Question

I have a module with custom submenu for transfers in Odoo9.
In the xml, I have this code:
<record id='action_menu_location_transfer_server' model='ir.actions.server'>
<field name="name">Custom Transfers</field>
<field name="model_id" ref="model_wizard_location_transfers_internal_transfer"/>
<field name="state">code</field>
<field name="code">action = self.custom_get_transfer_views(cr, uid, context=context)</field>
<field eval="True" name="condition"/>
</record>
<menuitem id="menu_refund_returns"
name="Custom Transfers"
action="action_menu_location_transfer_server"
parent="stock.menu_stock_warehouse_mgmt"
sequence="1"
groups="base.group_user"/>
But in Odoo12, if I try to use the code, it shows this error:
Odoo Server Error
Traceback (most recent call last):
File "/etc/odoo/server12/odoo/tools/safe_eval.py", line 350, in safe_eval

During handling of the above exception, another exception occurred:

'action = self.custom_get_transfer_views(cr, uid, context=context)'
What is the problem with the code for Odoo 12?
I have tried with self, record, object and nothing changes.

Answer 1

you can try this
<record id='action_menu_location_transfer_server' model='ir.actions.server'>
<field name="name">Custom Transfers</field>
<field name="model_id" ref="model_wizard_location_transfers_internal_transfer"/>
<field name="state">code</field>
<field name="code">model.custom_get_transfer_views()</field>
<field eval="True" name="condition"/>
</record>
the 'cr, uid,' no longer used in v12,
you can add the code of the 'custom_get_transfer_views' method to correct
