TypeError：_get_category（）需要恰好6個參數（給出4個參數）

究竟是什麼錯？TypeError：_get_category（）需要恰好6個參數（給出4個參數）

我試圖運行的代碼和我收到以下錯誤

我重視的回溯。

您正在將錯誤的參數傳遞給函數。

嘗試使用此代碼：

def _get_category(self, cr, uid, ids, field_names, arg, context=None): 
    #function logic 
    return

我想這還是同樣的問題 –

編輯與回溯你的問題編寫代碼。 –

我貼有traceback –

檢查壓痕，你_name和_description縮進看起來是錯誤的。

你可以這樣

def _get_category(self, cr, uid, ids, field_names, arg, context=None): 
    # Your Logic 
    # I need to know where is category_id ?? 

_name = 'module.level' 
_description = "Module Level" 
_columns = { 
    'name': fields.char('Level', size=20), 
    'category_id': fields.function(_get_category, type='many2one', relation="module.category", method=True, string='Session'), 
}
