「モジュール」オブジェクトは、Djangoのコンソールでサーバーランタイムで呼び出し可能けどOKではありません

Question

変なふうに、それは前に働いており、今ではない：私は変更する場合

Exception Value:  
'module' object is not callable 
Exception Location: C:\work\Portman\core\models\pmo_review_task.py in save, line 38 

：

は、次のエラーを取得"core.models import sc_review_task"を "from core.models import *"に変更すると、エラーメッセージが "global name sc_review_task is not defined"に変更されます。

私はDjangoの管理を実行し、実行している場合：core.modelsから がsc_review_task = sc_review_task（）

すべてがOKに見えるインポート - なしエラーメッセージを。

は私が、私は:)髪を失う

pmo_review_taskよこれを理解助けてください（ライン38は "付けたnewtask = sc_review_task（）" である）：

Answer 1

... pmo_review_taskで

をあなたの名前空間を確認します（ライン38 "は付けたnewtask = sc_review_task（）" である）、それは、newtask=sc_review_task.sc_review_task()

Answer 2

あるべきエラーはあなたが実行しようとしているということであるように見えますsc_review_task.sc_review_taskの代わりにsc_review_task

この種の間違いを防ぐために、小文字とクラスを大文字で指定する必要があります。すなわち、モジュールはsc_review_taskとクラスScReviewTaskです。よりinforationについては

Package and Module Names

Modules should have short, all-lowercase names. Underscores can be used in the module name if it improves readability. Python packages should also have short, all-lowercase names, although the use of underscores is discouraged.

...

Class Names

Almost without exception, class names use the CapWords convention. Classes for internal use have a leading underscore in addition.
