I'm working with ruby 2.5.5 and I'm starting the server like so:

RAILS_MASTER_KEY=[MY_KEY] RAILS_ENV=staging MY_DATABASE_PASSWORD=[MY_PW] bin/rails server -b 0.0.0.0

that works, now I want to generate migrations like so:

RAILS_MASTER_KEY=[MY_KEY] RAILS_ENV=staging MY_DATABASE_PASSWORD=[MY_PW] bin/rails generate migration CreateJoinTableMyTable column1 foreignKey

And I get the following error:

/path/to/.rvm/gems/ruby-2.5.5/gems/activesupport-5.2.3/lib/active_support/encrypted_file.rb:96:in `handle_missing_key': Missing encryption key to decrypt file with. Ask your team for your master key and write it to /Users/BaxterStockman/empiric/hyperion-backend-webapp/config/master.key or put it in the ENV['RAILS_MASTER_KEY']. (ActiveSupport::EncryptedFile::MissingKeyError)

I also wrote the RAILS_MASTER_KEY into ~/.bashrc and reload the profile but that didn't do anything.

Anyone an idea why this error gets thrown?

CodePudding user response：

What's the rails version? It shows you the error that you should have a file config/master.key in app folder. It's required to decrypt the credentials.yml.enc.

Just add that file by asking your colleagues or if you don't have one, generate via

EDITOR="code --wait" rails credentials:edit

You might google which EDITOR= instead of code you'd use as I don't know that. Just make sure the editor won't be closed immediately, that's why for VSCode I had to use --wait argument.

Afterwards, you might place RAILS_MASTER_KEY in credentials.yml.enc.

Since Rails 5.2 credentials file appeared, so you don't need to store keys in operating system's ENV variables.
