python manage.py test
を実行するとValueError
が表示されます。私のプロジェクトの名前はfellow_go
で、現在pickup
というアプリで作業しています。
このエラーは、比較的最近のDjangoへのコミットで追加されていることに注意してください: 修正#24452-ネストされたパスでのHashedFilesMixinの正確性を修正しました。 。

私のコードの何が問題なのか教えてください。
実行してみてください:
python manage.py collectstatic
テストは現在機能していますか?その場合、これは問題を引き起こす構成であるかもしれません:
STATICFILES_STORAGE = 'whitenoise.Django.GzipManifestStaticFilesStorage'
関連する:
https://stackoverflow.com/a/32347324/2596187
Django documentation: https://docs.djangoproject.com/en/1.11/ref/contrib/staticfiles/#Django.contrib.staticfiles.storage.ManifestStaticFilesStorage。 manifest_strict
この「Missing staticfiles manifest entry」エラーを防ぎながらDjango 1.11(またはそれ以降))プロジェクトで WhiteNoise モジュールを引き続き使用する場合は、無効にする必要があります。 Django documentation で説明されているように、継承を使用してmanifest_strict
属性。
それを達成する方法は?
まず、プロジェクトディレクトリにstorage.py
ファイルを作成します。
from whitenoise.storage import CompressedManifestStaticFilesStorage
class WhiteNoiseStaticFilesStorage(CompressedManifestStaticFilesStorage):
manifest_strict = False
次に、STATICFILES_STORAGE
ファイルのsettings.py
定数を編集して、次のようなこの新しいクラスを指すようにします。
STATICFILES_STORAGE = 'my_project.storage.WhiteNoiseStaticFilesStorage'
whitenoise
パッケージでは必ずしもそうとは限りません。 STATIC_STORAGE
をDjango.contrib.staticfiles.storage.ManifestStaticFilesStorage
に変更すると、 Django 1.11 で始まるテストの実行中に同じエラーが生成されます。
ManifestStaticFilesStorage
はstaticfiles.json
が存在することを期待し、 含む ファイルが要求されたために発生します。 ./manage.py collectstatic
を実行して再試行すると、これを確認できます。
DEBUG == True
、ManifestStaticFilesStorage
が 非ハッシュ urlsに切り替わると、開発時にこのエラーは通常表示されません。
これを克服するには、次のことを確認する必要があります。
STATICFILES_STORAGE = 'Django.contrib.staticfiles.storage.StaticFilesStorage'
これがデフォルトです。
1つの方法は、テストクラスの設定をオーバーライドすることです。
from Django.test import TestCase, override_settings
@override_settings(STATICFILES_STORAGE='Django.contrib.staticfiles.storage.StaticFilesStorage')
class MyTest(TestCase):
pass
またはメソッド:
from Django.test import TestCase, override_settings
class MyTest(TestCase):
@override_settings(STATICFILES_STORAGE='Django.contrib.staticfiles.storage.StaticFilesStorage')
def test_something(self):
pass
