I have some code that I would like to automatically execute on a per-project basis when I start up rails c. In one of my Rails 6 projects, I just created a .irbrc file at the top-level of the project, and it successfully executes as expected.
However, for a new Rails 7 (API-only) project that I am working on, the .irbrc file is ignored. I am using rvm, which wants to set the IRBRC environment variable to another file. However, even this config file isn't executed. I've tried both unset IRBRC and export IRBRC=.irbrc, but neither of these by themselves solves the issue.
I finally added gem "irb" to my GEMFILE, ran bundle install. I then ran IRBC=.irbc rails c and then within the console session I invoked IRB.start and it finally loaded the script!
How can I get Rails 7 to properly load my project specific .irbrc file when using the console (only)?
Found a solution here: https://stackoverflow.com/a/57526113/8005367
Apparently you can now add an initializer file (ex: /config/initializers/console.rb) to configure the console when it runs:
Rails.application.console do
puts "Initializing the Rails console..."
# console configuration here!
end
I've tested and confirmed that this properly executes only when running the console
