Configure generators for API only applications. It basically hides everything that is usually browser related, such as assets and session migration generators, and completely disable helpers and assets so generators such as scaffold won't create them. On Rails 6.1 this will be fixed hence the new query will be: SELECT users. FROM users WHERE users.active!= 't' OR users.admin!= 't' Here’s the rollout plan: Rails 5.2.3 acts as NOR Rails 6.0.0 acts as NOR with a deprecation message Rails 6.1.0 act as NAND This is the PR in case you want to know more.

Digest version to set up the secret key in the production environment in Rails 5.1
$ rails secrets:setup
-> copy the long secret key in the first line and set it as an environment variable RAILS_MASTER_KEY when executing rails$ rails secret
-> you will get the longer key; copy it$ EDITOR=vim rails secrets:edit
write the following and save it from vim
Errors in the production environment when I run 'rails server'
I've developped my application happily in the development environment. But it's high time I prepared for the production environment, and I tried
$ rails server --environment production
and got
An unhandled lowlevel error occurred. The application logs may have details.
Oh, no...
Next, I tried
Next, I tried
$ rails secrets:setup
which was introduced in Rails 5.1. But the error still remained. Going down in to the rails library, I got the point where I was wrong.
Anyway, you'll get the following output wehn you run rails secrets:setup
The encryption key 'a1e98ed29c40d7453a06bebeb815c0f3' in the first line is the most important key to protect the whole application and you must keep it secret. The key is automatically written down to config/secrets.yml.key.
Never commit it to your git repository, NEVER!
But usually you'll not commit it because the file config/secrets.yml.key is automatically added to .gitignore, so that the file is not to be committed.

But usually you'll not commit it because the file config/secrets.yml.key is automatically added to .gitignore, so that the file is not to be committed.
For rails execution, you need either to import config/secrets.yml.key from somewhere or to set the secret key in the environment variable RAILS_MASTER_KEY.
Actually, this in only the half of the necessary settings because what you did is to make a key to lock config/secrets.yml.enc, you treasure box. You still need to store your treasure.
This file, secrets.yml.enc is an encrypted yml file using your key. It looks like as follows.
This file, secrets.yml.enc is an encrypted yml file using your key. It looks like as follows.
To edit this file (if you use vim),
$ EDITOR=vim rails secrets:edit
The file looks like as follows.
Everything is commented out and nothing is specified above. You have to specify secret_key_base beneath production which is a secret key used for Cookie encryption. It is recommended to generate the secret key by using 'rails secret'.
Then, save it in your config/secrets.yml.enc by doing
Now, you have no error regarding the secret key in Rails.

By the way, you can store any kind of secret information here including database passwords. e.g.
Rails No Master.key Generated Video
You can use the encrypted database password from your code by
e.g. in config/database.yml.
Rails.application.secrets.postgresql_password
e.g. in config/database.yml.
