Welcome to another edition of This Week in #dev, a series of posts where we bring some of our most interesting Slack conversations to the public.
Understanding Rails.env.local?
Neil Carvalho shares a tip: Rails.env.local? returns true if the environment is either development or test.
Localizing models with Active Model
Joël Quenneville shares some exciting tips about ActiveModel. By using ActiveModel::Naming and ActiveModel::Translation, model-level translations can be applied to both persisted and in-memory models, like a Guest object for anonymous users. With a locale file, you can localize model and attribute names:
en:
activemodel:
models:
guest: Customer
attributes:
guest:
login: "Handle"
This allows access to methods for localized names:
@user.model_name.i18n_key #=> :guest
@user.model_name.human #=> "Customer"
@user.human_attribute_name("login") # => "Handle"
Additionally, Rails validation errors will also be localized. For more information, check out these resources:
