[英]Rails 5 Fog CarrierWave Photo Upload to Amazon S3 no implicit conversion of String into Array
I am an absolute beginner of Ruby on Rails.我是 Ruby on Rails 的绝对初学者。 There is an error that I encountered and do not know to deal with.
我遇到了一个错误,不知道如何处理。
WHAT I'D LIKE TO DO: Uploading a photo to Amazon S3 bucket.我想要做什么:将照片上传到 Amazon S3 存储桶。
Error: no implicit conversion of Array into String .错误:没有将 Array 隐式转换为 String 。
The Error comes out when @prototype.save fails in prototype#create action in prototypes_controller.rb当@prototype.save 在prototypes_controller.rb 中的prototype#create 操作失败时出现错误
Question: In order to solve this issue, when exactly should I convert Array into String?问题:为了解决这个问题,我应该在什么时候将 Array 转换为 String?

If anyone has encountered the error below, can you give me some clues?如果有人遇到下面的错误,你能给我一些线索吗? Any advice would be appreciated!
任何建议将不胜感激! Thanks in advance!
提前致谢!
I suggest you to add following lines inside CarrierWave.configure
block:我建议您在
CarrierWave.configure
块中添加以下几行:
config.ignore_integrity_errors = false
config.ignore_processing_errors = false
config.ignore_download_errors = false
It could help to get more understandable error.它可以帮助获得更容易理解的错误。
Take a look at the line where the fog_directory
is being set看一下设置
fog_directory
行
config.fog_directory = 'my_bucket_name',
See that comma at the end?看到最后那个逗号了吗? It turns it into an array.
它把它变成一个数组。
Easy mistake to make when the fog_credentials
bit is set to an object which requires commas at the end of every line.当
fog_credentials
位设置为需要在每行末尾使用逗号的对象时,很容易犯错误。
