Change plural form of generated model in rails?

Question

I\'m using this command:

rails generate model DayOfMonth day:integer

Rails generated the model \"DayOfMonth\" and the table \"day_of_months\".<

Answer 1

ActiveSupport::Inflector.inflections do |inflect|
 inflect.irregular 'day of month', 'days of month'
end

Answer 2

You have to say what's the plural form of 'day of month' in an initializer 'inflections.rb':

ActiveSupport::Inflector.inflections do |inflect|
     inflect.irregular 'day of month', 'days of month'
     inflect.irregular 'day_of_month', 'days_of_month'
end

That worked for me. Although, I'm still getting errors when defining associations to that model:

has_many :days_of_month

Answer 3

You could just edit the migration and then add

Rails 3.2+ / 4+

class DayOfMonth < ActiveRecord::Base
   self.table_name = "days_of_month"
end

Rails 3

class DayOfMonth < ActiveRecord::Base
  set_table_name "days_of_month"
end
