How to pass information from a form as an object?

Question

Ruby on Rails

In rails, you can collect information from several fields into an array in this way:
view:

<%= text_field_tag 'dogs[]' %>
<%= text_field_tag 'dogs[]' %>

controller:
puts params[:dogs] # => ["Bailey", "Max"]
How can I pass information from forms to the controller as an object?
for example: language - dropdown list, translation - text field. That is, the fields are the dynamic
structure of the transferred object:

{
  "ru": "собака",
  "en": "dog"
}

Answer 1

<%= text_field_tag 'dogs[ru]' %>
<%= text_field_tag 'dogs[en]' %>
