I have a model Products::Car. How can I translate its attributes?
I have already tried this:
activerecord: models: products: car: "Автомобиль" attributes: products: car: owner: "Владелец" And this:
activerecord: models: products_car: "Автомобиль" attributes: products_car: owner: "Владелец" But if I try to use Products::Car.model_name.human it still says "Car". My other translations work well, and the language is set to :ru.

The namespace in Ruby is defined by prefixing the keyword module in front of the namespace name. The name of namespaces and classes always start from a capital letter. You can access the sub members of double with the help of :: operator. It is also called the constant resolution operator.
What is the difference between a class and a module? Modules are collections of methods and constants. They cannot generate instances. Classes may generate instances (objects), and have per-instance state (instance variables).
The method definitions look similar, too: Module methods are defined just like class methods. As with class methods, you call a module method by preceding its name with the module's name and a period, and you reference a constant using the module name and two colons.
You can define and access instance variables within a module's instance methods, but you can't actually instantiate a module.
I have checked 'model_name.human' source code and found 'i18n_key' method. I have tried this:
irb(main):006:0> Products::Car.model_name.i18n_key => :"products/car" Then I changed my yml file to this:
activerecord: models: products/car: "Автомобиль" attributes: products/car: owner: "Владелец" and it works!
EDIT:
For further reference: the i18n_key is set in the initializer of ActiveModel::Name https://github.com/rails/rails/blob/375a4143cf5caeb6159b338be824903edfd62836/activemodel/lib/active_model/naming.rb#L147
and it is simply based on
MyClass.name.underscore If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
