我在Docker下运行的RAILS中有一个应用程序,我希望它使用Gem Carrierwave将文件上传到S3存储桶上
当我上传文件时,一切似乎都很好,但是文件从未出现在我的存储桶中。
我想念什么吗?也许是权限还是开放端口?
我的配置与之相同:
aws.rb
require 'aws-sdk'
Aws.config.update({
region: ENV['aws_region'],
credentials: Aws::Credentials.new(ENV['aws_access_key_id'],ENV['aws_secret_access_key'])
})
carrierwave.rb
CarrierWave.configure do |config|
config.storage = :aws
config.aws_bucket = ENV['aws_bucket']
config.aws_acl = 'public-read'
config.aws_authenticated_url_expiration = 60 * 60 * 24 * 7
config.aws_attributes = {
expires: 1.week.from_now.httpdate,
cache_control: 'max-age=604800'
}
config.aws_credentials = {
:region => ENV['aws_region'],
:force_path_style => true,
:signature_version => 'v4',
:credentials => Aws::Credentials.new(ENV['aws_access_key_id'],ENV['aws_secret_access_key']),
}
end

def store_dir

end

end
def cache_dir

end
def extension_whitelist

end
def filename
"#{File.basename(file.filename,".*")}__#{secure_token}.#{file.extension}" if original_filename.present?
end
protected
def secure_token
var = :"@#{mounted_as}_secure_token"
model.instance_variable_get(var) or model.instance_variable_set(var, SecureRandom.uuid)
end
end
答案 0 :(得分:0)
第一:
我向自己保证,“ cache_dir
”文件夹是可访问的,并设置为系统和Docker之间的共享卷
我向自己保证,我的AWS Bucket文件夹已创建,并且可以从公众访问
问题似乎来自我的“ secure_token
”的“ filename
”和“ DocumentUploader
”方法
我不得不更改
"#{File.basename(file.filename,".*")}__#{secure_token}.#{file.extension}" if original_filename.present?
作者
"#{File.basename(original_filename,".*")}__#{secure_token}.#{file.extension}" if original_filename.present?
错误消息是
无法修改冻结的NilClass模型。instance_variable_get(var)或 model.instance_variable_set(var,SecureRandom.uuid)
我很难找到它,因为它基本上保持沉默。它没有显示在任何日志,输出或屏幕中。当我到处都放痕迹时,我就留茬了;)
