I’m developing a custom POS module in Odoo 18 and could use some guidance. Each customer can have multiple codes, which are stored in a tab on the customer page. I want to create a dropdown in the POS that displays only the codes for the selected customer and allows me to save the selected code for the POS order. How is it possible?

Hello Odoouser! Here’s how you can dynamically populate a dropdown in your POS module based on the selected customer in Odoo 18:
First, define a new model to store the customer-specific codes. This model should have a many2one relationship with the
res.partnermodel (customer) and a field to store the code.Next, in your POS module, create a new field in the
pos.ordermodel to store the selected code. This field should be a many2one relationship with your custom code model.Override the
_prepare_pos_order_line_valsmethod in your POS module to include the selected code when creating the order line. This ensures the code is saved with the order.Create a new QWeb template to add the dropdown to the POS interface. Use JavaScript to dynamically update the dropdown options based on the selected customer. You can use an RPC call to fetch the codes for the selected customer from the server.
Finally, ensure that the JavaScript code is correctly linked to the QWeb template and that the RPC call is correctly configured to fetch the data from your custom model.
