Dynamical attr_accessible attributes

[HendrikRoth]

Instead of defining each several language for attr_accessible

class Product < ActiveRecord::Base
  attr_accessible :name_en, :name_de, :name_fr
  translates :name
end

it would be nice to set only one central attribute.

class Product < ActiveRecord::Base
  attr_accessible :name_translations
  translates :name
end

Is there a way to change this behavior?

You can certainly do this and assign the name_translations hash directly. Does it work for your use case?

Do you have an example?

robworley: my problem is the attr_accessible part. at the moment i have to add :name_en, :name_fr, etc.

Is there another way to have this dynamic for several locales?

[robworley]

Sorry for the late response. Here's one way to do it:

class Product < ActiveRecord::Base
  I18n.available_locales.each { |locale| attr_accessible "name_#{locale}" }
  translates :name
end

Then in the view template:

<%= form_for @product do |f| %>
  <% I18n.available_locales.each do |locale| %>
    <%= f.label "name_#{locale}" %>
    <%= f.text_field "name_#{locale}" %>
  <% end %>
  <%= submit_tag %>
<% end %>

 I18n.available_locales.each { |locale| attr_accessible "name_#{locale}" }

Is there a nice way to do this in Rails 4? I understand I have to list all fields as strong params, but I've been unable to find any nice looking solution if there are many locales and a lot of translated fields.
