Rails console trick I had no idea about
.irbrc to make interactive console comfortable is a highly-rewarding activity. You gets instant boost of productivity and there are less frustrations. There were numerous posts and tips featured in Ruby Weekly on this topic recently.
I’ve been making my
.irbrc more useful too. The harder part was always distributing those changes to remote servers. For example to have those goodies available in Heroku console. And not only for me. There are multiple ways to achieve that, duh. The one that stick though was close to the app code:
# script/likeasir.rb # Nice things to have when entering production console # load 'script/likeasir.rb' def event_store Rails.configuration.event_store end def command_bus Rails.configuration.command_bus end # ...
You’d open the console first and load the helpers next to the IRB session with:
And then Kuba showed me a neat trick that made this load step completely obsolete:
# config/application.rb module MyApp class Application < Rails::Application # ... console do module DummyConsole def event_store Rails.configuration.event_store end def command_bus Rails.configuration.command_bus end end Rails::ConsoleMethods.include(DummyConsole) end end end
Now, whenever you load
bin/rails c, the
event_store methods will be present in the IRB session.
That’s it. That’s the trick I did not know about for years.
