[英]Blob Error with Active Storage Rails 5.2
I've just upgraded a 5.1.4. 我刚刚升级了5.1.4。 app to 5.2 and am trying to swap out Paperclip for ActiveStorage.
应用程序到5.2,我正在尝试将Paperclip替换为ActiveStorage。 At the moment when trying to update an existing record with an image, I get the following error:
在尝试使用图像更新现有记录时,我收到以下错误:
Unable to autoload constant ActiveStorage::Blob::Analyzable, expected /Users/Simon/.rvm/gems/ruby-2.4.0/gems/activestorage-5.2.0/app/models/active_storage/blob/analyzable.rb to define it
无法自动加载常量ActiveStorage :: Blob :: Analyzable,预期/Users/Simon/.rvm/gems/ruby-2.4.0/gems/activestorage-5.2.0/app/models/active_storage/blob/analyzable.rb来定义它
In my model: 在我的模型中:
has_one_attached :pic
In my controller: 在我的控制器中:
... ...
def update
respond_to do |format|
if @gin.update(gin_params)
format.html { redirect_to @gin, notice: 'Gin was successfully updated.' }
format.json { render :show, status: :ok, location: @gin }
else
format.html { render :edit }
format.json { render json: @gin.errors, status: :unprocessable_entity }
end
end
end
... ...
def gin_params params.require(:gin).permit(:name, :text, :snippet,
:pic, :slug, :abv, distillery_attributes: [:id, :name], botanical_ids:
[]) end
In storage.yml: 在storage.yml中:
amazon:
service: S3
access_key_id: <%= Rails.application.credentials.dig(:aws, :access_key_id) %>
secret_access_key: <%= Rails.application.credentials.dig(:aws, :secret_access_key) %>
region: xx-xxxx-x
bucket: xxxxxxx
I set the access keys via rails credentials:edit
我通过
rails credentials:edit
设置访问密钥rails credentials:edit
In development.rb: 在development.rb中:
config.active_storage.service = :amazon
In my views: 在我看来:
<%= image_tag @gin.pic, class: "border shadow-lg" %>
I've been reading though http://edgeapi.rubyonrails.org/classes/ActiveStorage/Blob/Analyzable.html but it doesn't make too much sense to me. 我一直在阅读http://edgeapi.rubyonrails.org/classes/ActiveStorage/Blob/Analyzable.html,但这对我来说并没有多大意义。
The error has made me look for the file at app/models/active_storage/blob/analyzable.rb
but I can't see it in my app? 该错误让我在
app/models/active_storage/blob/analyzable.rb
查找该文件,但我在我的应用程序中看不到它?
What have I missed? 我错过了什么?
I've got exactly same error. 我有完全相同的错误。 For me it was because credentials for AWS S3 were missing (it was missing from credentials.yml.enc )
对我而言,这是因为缺少AWS S3的凭据( 凭证中缺少凭证。 )
Resolved 解决
Whilst I already had gem 'aws-sdk-s3', '~>1'
I didn't have require: false
虽然我已经有了
gem 'aws-sdk-s3', '~>1'
我没有require: false
I had this exception but the cause of my issues was that active storage was silently failing to load its configurations from storage.yml: 我有这个例外,但我的问题的原因是主动存储无法从storage.yml加载其配置:
Loading the file in a rails console shows the exception (whereas rails swallows the exception when loading active storage config): 在rails控制台中加载文件会显示异常(而rails在加载活动存储配置时会吞下异常):
YAML.load(ERB.new(File.read("#{Rails.root}/config/storage.yml")).result)
NoMethodError: undefined method `[]' for nil:NilClass
I had a comment with an ERB interpolation that was invalid. 我的ERB插值评论无效。 Fixing this fixed my issue.
解决这个问题解决了我的问题。
Launch rails active_storage:install
and rails db:migrate
启动
rails active_storage:install
和rails db:migrate
Add this gem gem 'aws-sdk-s3', '~>1'
and bundle
添加这个gem
gem 'aws-sdk-s3', '~>1'
并bundle
Delete your credential.yml.enc
and your master.key
if exists 删除您的
credential.yml.enc
和master.key
如果存在)
Launch EDITOR=vim rails credentials:edit
and puts your credentials 启动
EDITOR=vim rails credentials:edit
并放置您的凭据
And normally rails s
it should work 通常它应该工作的
rails s
