🌍 Extending Faker with Dynamic Fallback Locales for Content Variation

When localizing test data, you might need fallbacks if a translation is missing or empty. You can implement a dynamic fallback mechanism by cycling through a prioritized list of locales. This ensures robust data generation across cultures without interruptions.

# Setup primary and fallback locales
Faker::Config.locale = 'de'
Faker::Config.available_locales = ['de', 'es', 'en']

# Fallback method for any Faker call
def fallback_faker(method_chain)
Faker::Config.available_locales.each do |loc|
Faker::Config.locale = loc
value = method_chain.reduce(Faker) { |obj, m| obj.send(m) }
return value unless value.nil? || value.to_s.empty?
end
nil
end

# Example: Try German, then Spanish, then English
puts fallback_faker([:Book, :title]) #=> "Der Zauberberg" or first available
puts fallback_faker([:Name, :first_name]) #=> Fallback across locales
