11個のフィールドと1個の画像アップロードフィールドを持つフォームがあります。入力して送信を押すと、整数が必要であるというTypeErrorが表示されます。imagefieldを削除しても、このエラーは発生しません。イメージディレクトリを確認すると、エラーがスローされる前にファイルがサーバーに保存されます。

Forms.py：

    seller_email = forms.EmailField(max_length="", required=True, widget=forms.TextInput(attrs={'placeholder': "jsmith@stevens.edu"}))

    classcode= forms.CharField(required=True, widget=forms.TextInput(attrs={'placeholder':"MA115"}))

settings.pyスクリプトには、次の行があります。

FILE_UPLOAD_PERMISSIONS '0760'

周りに引用符を付けないでください。整数が必要な場合に、2番目の引数として文字列を使用してos.chmod（）を呼び出そうとしています。具体的には、8進数のパーミッション値です。Pythonでは、先行0が付いた数値は自動的に8進数値と見なされ、整数に変換されます。したがって、代わりに次の行を使用してください。

FILE_UPLOAD_PERMISSIONS = 0760

ちなみに、settings.pyで等号を使用しないのはなぜですか？

上記の問題に対する更新された解決策は、settings.pyファイルにこのスニペットを追加することです。

FILE_UPLOAD_PERMISSIONS = 0o760

を使用する必要があることに注意してくださいo。
