Ruby Question

Requiring ActiveRecord on IRB - Ruby (NO Rails)

How can I load

on an IRB session?

I have the following

# config/app.rb
require 'active_record'

adapter: 'sqlite3',
database: 'db/mydb.sqlite3'

But when I start IRB and try to load it

irb#1(main):001:0> require config/application.rb

I get

NameError: undefined local variable or method `config' for main:Object
Did you mean? conf

I'd like to be able to interact with my ActiveRecord objects from IRB.
I'm NOT using Rails but only ActiveRecord.



Two things to change here:

  1. Always put quotes around the path you're requiring. The reason Ruby is saying "undefined local variable or method" is that it's trying to interpret config as a variable name. Put the name in quotes and it won't.
  2. Use require_relative when loading files that are part of your application. require only looks in the default

    require_relative 'config/application.rb'
