系统配置
Rails 版本:7.0.0
ruby 版本:3.0.3
最佳答案
首先您需要创建 blob 文件以用于事件存储。
def attach_doc(doc_param)
doc = ActiveStorage::Blob.create_and_upload!(
io: doc_param,
filename: doc_param.original_filename,
content_type: doc_param.content_type
)
document = context[:current_user].documents.doc.attach(doc)
end
In rails < 7.0 method is ActiveStorage::Blob.create_after_upload
关于ruby-on-rails - ActiveStorage - 无法找到或构建 blob:预期可附加，得到 #<ActionDispatch::Http::UploadedFile，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/70550808/
