ruby-on-rails-5.2

问题 I just upgraded from 5.1 to 5.2 and I'm quite confused about this 'better' methodology to storing secrets... Maybe I'm not understanding, but it seems like now development and production have been 'merged' into a SINGLE SECRET_KEY_BASE as well as master.key ... is this correct? If not, how do I use a separate master key and SECRET_KEY_BASE in development? What if I have developers helping me and I don't want them to know my master key (or secrets) I use in production? 回答1: Rails 5.2 changed

问题 Is there a way to validate attachments with ActiveStorage? For example, if I want to validate the content type or the file size? Something like Paperclip's approach would be great! validates_attachment_content_type :logo, content_type: /\Aimage\/.*\Z/ validates_attachment_size :logo, less_than: 1.megabytes 回答1: Well, it ain't pretty, but this may be necessary until they bake in some validation: validate :logo_validation def logo_validation if logo.attached? if logo.blob.byte_size > 1000000

问题 First, let me describe the problem. I'm using RSpec to run a script to generate some test data. RAILS_ENV=development rspec spec/dev/food/food_upload.rb The script looks like this. image = fixture_file_upload(Rails.root.join('spec', 'resources', 'test2.png'), 'image/png') (0..200).each { food = FactoryBot.build :food p "Loading #{food.name}" expect { post :upload, params: { "foodUpload_foodName"=> food.name, "foodUpload_image"=> image } }.to change(Food, :count).by(1) .and change(Image,

NOTE: I'm using Rails 5.2 回答1: This question challenged me, so I did some test on my dummy app with local storage. I have the usual model User which has_one_attached :avatar On local storage files are saved on /storage folder, under subfolders named randomly with a string of two characters. Informations related to files are stored in two

问题 I pushed out to heroku last night, and now today my pushes are failing with the following error. Heroku status appears to be ok. My heroku config has RAILS_MASTER_KEY set to my master.key. That did not help. Any experience this...or, able to point me towards a fix? Command: 'bin/rails runner "puts %Q{heroku_detecting_active_storage_config=#{Rails.application.config.active_storage.service}}"' failed unexpectedly: remote: !

问题 We have a use case for mounting a mock engine to process sessions when developing locally in which a custom session middleware calls the mock engine via Net::http request when a request comes through. When there is code change, the reloader is triggered and here calls the ActiveSupport::Dependencies to start unloading. Then the request is pass down to our custom session middleware and the http request is fired. However since the http request calls to a mountable engine, it goes thought the

问题 I have a dropdown.yml file that stores all my dropdown values for my multi-select fields in my forms. It is not environment dependent, so I do not have :development, :production, etc. I would like cache the file into a constant so I can use across my app. I found this command. config = Rails.application.config_for(:payment) However, it looks like it is environment dependent. What is the best way to add the yml? Second, should I use locales for this instead of a custom yml file? config
