Hello everyone,

I'm using Odoo 8 (but I cannot access the code, so I cannot debug) and I'm connecting to its API through an app written in ruby. I'm able to create an order sale and confirm it but I cannot convert it into an invoice.

Here an example of my code, it's ruby but is not important for what I would ask.

#this is a wrapper to be more DRY and avoid to repeat code for every call
 def execute_odoo_command(odoo_model, odoo_command, values)
    @models.execute_kw(ODOO_DB, @uid, ODOO_PASSWORD, odoo_model, odoo_command, values)
  end

    invoice_values = { advance_payment_method: 'lines', active_ids: [odoo_order_lines] }

execute_odoo_command('sale.advance.payment.inv', 'create_invoices', [invoice_values])

I'm sure the wrapper works because I'm able to create order_sales and confirm them (moreover I use it somewhere else and everything goes well)I deduce that the mistake is in the way I pass the invoice_values to create_invoice, so my question is the following: which params and how structured I should pass to create_invoices to be able to convert a confirmed order sale into an invoice?

Thank you for your help
