NameError：グローバル名 'has_no_changeset'が定義されていません

Question

OK - Python newbie here - 私は本当に馬鹿なことをしていると思います。

私はエラーNameError: global name 'has_no_changeset' is not definedを55行目（ここでは、関数has_no_changesetを呼び出してみます）に取得します。

あなたは現在のクラスのメソッドを参照するときに、明示的にself（または、あなたのケースで、me）を指定する必要があります。

if me.has_no_changeset(ticket): 

あなたはme代わりのselfを使用している - それは法的なのですが、強く落胆した。メンバ関数の最初のパラメータは、self：

def validate_ticket(self, req, ticket): 
    # [...] 
    if self.has_no_changeset(ticket):
