Introduction

It seems that the plural definition of the reserve model automatically becomes reserf It was discovered by an error message.

NameError (uninitialized constant User::Reserf):

Solution

I was able to solve it by defining the plural as follows.

config/initializers/inflections.rb

ActiveSupport::Inflector.inflections(:en) do |inflect|
  inflect.irregular "reserve", "reserves"
end
