Question

I am using database with multiple language support. Now the problem is that I need to enter my language into query in order to get information and it is fine, but what would be optimal way to store that information.

On client side it will be stored in cookies, of course. Now only way I can think of is making global variable on class and then use it in my functions. Is that only way?

Example code

private string lang = Infrastructure.UserSettings.Language(); // I don't have this implemented yet

[HttpGet]
public dynamic List()
{
    string lang = "English"; // That's why I set it here manually for testing

    var items = _db.Items.OrderByDescending(x => x.ID).Select(x => new
    {
        ID = x.ID,
        Price = x.Price,
        Name = x.ItemTranslations.Where(y => y.Language.Name == lang).Select(y => y.Name).SingleOrDefault(),
        Category =  new {
            ID = x.Category.ID,
            Name = x.Category.CategoryTranslations.Where(y => y.Language.Name == lang).Select(y => y.Name).SingleOrDefault()
        }
    });

    return items;
}

My question: Is this good way of doing this or there is some more optimal way?

Answer 1

A cookie is sent to the server on every page request. If the setting is available in the cookie, just read the cookie when you need to do a query. There is no performance overhead for reading a cookie that is already present.
