這是錯誤追溯。的account_voucher模型

根據代碼，button_proforma_voucher方法應被調用，但控制不來高達是與錯誤之前提出。

Answer 1

有小數精確定義digits_compute，同時數字不與舊的API代碼浮法領域工作的工作的問題。

發生這種情況是因爲我從v8的github中提取了最新的代碼，但它並沒有使用最新的代碼，所以我需要更新該字段定義。

import openerp.addons.decimal_precision as dp 


_columns = { 
    'currency_rate' : fields.float(digits_compute=dp.get_precision('Account'), string='Currency Rate'), 
}
