OrangeJetpack.Localization

Orange Jetpack Localization is a library that simplifies the storage and retrieval of multi-language POCOs in a database. It provides interfaces and attributes for setting up localizable classes and extension methods for setting and getting objects and properties.

Getting Started

Install-Package OrangeJetpack.Localization

Creating Localizable Classes

Localization provides an interface and a property attribute for setting up classes that can be localized:

public class Planet : ILocalizable
{
    [Localized]
    public string Name { get; set; }
}

Settings Properties from Dictionaries

You can use the Set() extension method to set properties directly:

var planet = new Planet();

var name = new Dictionary<string, string>
{
    {"en", "Earth"},
    {"ru", "Земля"},
    {"ja", "地球"},
    {"ar", "أرض" }
};

planet.Set(i => i.Name, name);

Setting Properties from Model Binding:

[HttpPost, ValidateAntiForgeryToken]
public ActionResult Edit(Planet planet, LocalizedContent[] name)
{
    planet.Set(i => i.Name, name);
    
    //...

    return View();
}

Localizing an Object

You can use Localize() extension methods to get a localized instance of an ILocalizable class or collection.

Single Object

var planet = _db.Planets.SingleOrDefault(i => i.Id == 1).Localize("en");

Localizing a Collection

var planets = _db.Planets.Localize<Planet>("en");

Localizing Specific Properties

var planets = _db.Planets.Localize("en", i => i.Name);

Controlling Depth of Localization

// localizes only root objects (DEFAULT)
var planets = _db.Planets.Localize<Planet>("en", LocalizationDepth.Shallow);

// localizes only root objects and immediate children (properties and collections)
var planets = _db.Planets.Localize<Planet>("en", LocalizationDepth.OneLevel);

// localizes only root objects and all children recursively
var planets = _db.Planets.Localize<Planet>("en", LocalizationDepth.Deep);
