Require a gem in rails

Question

I'd like to include unitwise in my project, so I added it in the Gemfile and I want to use the core extensions of this gem in a model, so I have to require 'unitwise/ext' which isn't by default. Should I require this file in every models I use it, or is there a way to require it one time for the whole project?

Answer 1

You can require it once either by creating an initializer for it, or adding this line to application.rb.

require 'unitwise/ext'

Answer 2

You could create separate ruby file in config/initializer/ to require unitwise/ext which will be available in all place in the project or you could require in application.rb, here also it will be available everywhere in application.

It is better add one line in application.rb, instead creating separate file in initializer to require that file.
