Friendly GUI for managing your I18n translations.
By default it uses Redis as I18n backend for translations, but you can add your own key-value backend.
Bundle Riddick gem:
# Gemfile
gem 'riddick'
Mount Riddick server:
# config/routes.rb
require 'riddick/server'
MyApp::Application.routes.draw do
mount Riddick::Server.new, at: 'riddick', as: 'riddick'
end
Add a link to the GUI:
# app/views/layouts/application.html.erb
<%= link_to t('.translations'), :riddick %>
Tell I18n to use key-value-backend (if you haven't already):
# config/initializers/i18n.rb
I18n.backend = I18n::Backend::Chain.new I18n::Backend::KeyValue.new(Redis.new), I18n.backend
You can also change the translations of Riddick GUI. Following keys can be changed:
riddick:
head:
title: 'Welcome to Riddick!'
nav:
brand: 'Riddick'
all: 'All translations'
my: 'My translations'
default: 'Default translations'
form:
select:
placeholder: 'en.greeting'
button: 'Change'
textarea:
placeholder: 'Hello World!'
table:
header:
path: 'Path'
translation: 'Translation'
actions: 'Actions'
popover:
my: 'My translation'
default: 'Default translation'
edit:
my: 'Edit'
default: 'Edit'
delete: 'Delete'
confirm: 'Are you sure?'
notice:
empty: 'You have no translations yet.'
set:
success: 'Translation successfully stored!'
error: 'Error: either path or translation is empty!'
del:
success: 'Translation successfully deleted!'
error: 'Error: no such key or key empty!'
truncation: '...'
For example to change the page title of the GUI on the German page:
# config/locales/riddick.de.yml
de:
riddick:
head:
title: 'Willkommen bei Riddick!'
By default Riddick will try to guess which backends to use, assuming your using a chained backend.
For the key-value backend it will ask the chain backend for it's backends with I18n.backend.backends
and will use the first one of type I18n::Backends::KeyValue
.
For the fallback backend it will ask the chain backend for it's backends with I18n.backend.backends
and will use the first one of type I18n::Backends::Simple
.
You can change this behavior by setting one or both backends (or even the chain explicitely):
# config/initializers/riddick.rb
Riddick::Backends.chain = MyChainBackend
Riddick::Backends.simple = MySimpleBackend
Riddick::Backends.key_value = MyKeyValueBackend
MyChainBackend
can be any backend which is kind ofI18n::Backend::Chain
.MySimpleBackend
can be any backend which is kind ofRiddick::Backends::Simple
.MyKeyValueBackend
can be any backend which is kind ofRiddick::Backends::KeyValue
.
Example:
MySimpleBackend = Riddick::Backends::Simple.new I18n.backend
MyKeyValueBackend = Riddick::Backends::KeyValue.new I18n::Backend::KeyValue.new(Redis.new)
You can also write your own backends by subclassing apropriate backend from Riddick and adding to it needed methods (see RDoc for details).
WARNING: Custom backends feature is still under development. You should NOT use it unless you want to help me to develop it.
Example:
class MyRedisBackend < Riddick::Backends::Redis
def delete_translation(k)
Rails.logger.info "Translation #{k} deleted"
super
end
end
If you want to write a completely different backend, you can subclass Riddick::Backends::KeyValue
.
In this case you can also implement the appropriate Value
class if needed (see RDoc for details).
Example:
class ActiveRecordBackend < Riddick::Backends::KeyValue
def delete_translation(k)
MyModel.find_by_key(k).destroy
end
def translations
hash = {}
MyModel.all.pluck(:key, :value).map { |k, v| hash[k] = ActiveRecordBackend::Value.new v }
hash
end
class Value < Riddick::Backends::KeyValue::Value
def initialize(string)
@object = MultiJson.decode string
end
def to_s
@object.inspect
end
end
end
We recommend you to switch to YAJL gem:
# Gemfile
gem 'yajl-ruby', require: 'yajl/json_gem'
Details: I18n uses MultiJson gem internally to encode / decode translation objects in key-value-backends. Unfortunately the default JSON gem is too strict about this and doesn't allow to decode plain strings, which is essential for a key-value-based backend.
Just copy assets from Riddick to you app's public directory:
# config/deploy.rb:
after :deploy do
target = File.join %W[#{release_path} public riddick]
run "cp -r `cd #{release_path} && bundle show riddick`/lib/riddick/public #{target}"
end
Details: Normally your using a proxy server like NGinx or Apache in front of your app.
Unfortunately the assets from a mounted Sinatra app will not be served because
they aren't in the public
directory of your app.
If your are using redis to store other stuff you can separate your I18n translations in namespace. Please use redis-namespace gem.
# Gemfile
gem 'redis-namespace'
Change your configuration in i18n.rb
# config/initializers/i18n.rb
I18n.backend = I18n::Backend::Chain.new I18n::Backend::KeyValue.new(Redis::Namespace.new(:riddick)), I18n.backend
Your I18n translations will be stored in riddick
namespace.
