Unable to introduce seed data into deployed rails app

Questions / Help

Hi!
I am Japanese.
My English is poor, so I apologize if it is not clear.

This is a continuation of the question here.

I want to submit seed data, but it fails.
What are the possible causes?

hoge@MacBook-Air-2 sample_app % flyctl ssh console -C "/rails/bin/rails db:seed"

If there are any other files you would like me to show you, please let me know.
We will add them to the site as they become available.

bin/rails needs to be run from the ‘/rails’ directory. Specifying the full path doesn’t work.

Easiest thing to do is to split the command up:

flyctl ssh console
cd /rails
bin/rails db:seed

If this is something you expect to do frequently, you can adjust the files in your bin directory to set the current working directory using:

bin/rails generate dockerfile --bin-cd
fly deploy

This change will enable flyctl ssh console -C "/rails/bin/rails db:seed" to work as a single command.

The value of Rails.env.downcase will be production when deployed.

Thank you very much!
I created db/enviroment/production.rb and was able to resolve the issue!
