Don’t like storing enums as integers in your database? Introducing...
String enums for Rails!! 🎉
- scopes
- validations
- accessor methods
- update methods
Add this line to your application’s Gemfile:
gem "str_enum"Add a string column to your model.
add_column :users, :status, :stringAnd use:
class User < ActiveRecord::Base
str_enum :status, [:active, :archived]
endThe first value will be the initial value. This gives you:
User.active
User.archivedAnd negative scopes
User.not_active
User.not_archiveduser = User.new(status: "unknown")
user.valid? # falseuser.active?
user.archived?user.active!
user.archived!<%= f.select :status, User.statuses.map { |s| [s.titleize, s] } %>Choose which features you want with (default values shown):
class User < ActiveRecord::Base
str_enum :status, [:active, :archived],
accessor_methods: true,
allow_nil: false,
default: true,
prefix: false,
scopes: true,
suffix: false,
update_methods: true,
validate: true
endPrevent method name collisions with the prefix and suffix options.
class User < ActiveRecord::Base
str_enum :address_status, [:active, :archived], suffix: :address
end
# scopes
User.active_address
User.archived_address
# accessor methods
user.active_address?
user.archived_address?
# update methods
