未设置必需的参数名称 - Django + Amazon S3

Question

我正在尝试为我的 Django 应用程序设置 Amazon S3，但我一直被告知“未设置必需的参数名称” '.当需要显示图像时，似乎会发生此错误。例如，它在没有图像的主页上工作正常。真的不知道我哪里做错了。我在 settings.py 中进行了以下设置。

INSTALLED_APPS = [
    'projects',
    'users.apps.UsersConfig',
    'crispy_forms',
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'storages',
]

#S3 BUCKET CONFIG

AWS_ACCESS_KEY_ID = 'acccess key'
AWS_SECRET_ACCESS_KEY = 'secret access key'
AWS_BUCKET_NAME = 'bucket name'


AWS_S3_FILE_OVERWRITE = False
AWS_DEFAULT_ACL = None
DEFAULT_FILE_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage'

Exception Type: ValueError at /projects/createListing
Exception Value: Required parameter name not set

Answer 1

正如@jordanm2 所说，我有 AWS_BUCKET_NAME 而不是 AWS_STORAGE_BUCKET_NAME

Answer 2

我刚刚将密钥 AWS_STORAGE_BUCKET_NAME = 'bucket-name' 粘贴到 settings.py 文件的顶部，它对我有用。

未设置必需的参数名称 - Django + Amazon S3

Required parameter name not set - Django + Amazon S3

django

amazon-s3

django-storage

boto3
