What is the simplest way to get translated name of ActiveRecord model class when I have an instance of it?
For example - I have model class like this:
class Category < ActiveRecord::Base ... end I have an instance of the class:
category = Category.first And I have YAML file config/locales/cs.yml:
cs: activerecord: models: category: Kategorie And I need to do this dynamicaly, even when I don't previously know with what model class' instance I will be dealing. So I don't want to explicitly specify "activerecord.models.category".
Is there an easy way to do this? I know, that I can do something like this
"activerecord.models.#{category.class.name.underscore}" But there has to be a better way to do this.

ActiveRecord::Base indicates that the ActiveRecord class or module has a static inner class called Base that you're extending.
In Active Record, objects carry both persistent data and behavior which operates on that data. Active Record takes the opinion that ensuring data access logic as part of the object will educate users of that object on how to write to and read from the database.
What is ActiveRecord? ActiveRecord is an ORM. It's a layer of Ruby code that runs between your database and your logic code. When you need to make changes to the database, you'll write Ruby code, and then run "migrations" which makes the actual changes to the database.
A model is a Ruby class that is used to represent data. Additionally, models can interact with the application's database through a feature of Rails called Active Record. To define a model, we will use the model generator: $ bin/rails generate model Article title:string body:text Copy.
See:

So, for example, on an AR class use:
Person.model_name.human or from an AR instance:
person.class.model_name.human If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
