How to translate content item obtained from GetContentItemIdAsync & GetAsync when using decoupled CMS with Blazor?

[lamualfa]

Query Content Item

Inject Interfaces

@inject IContentHandleManager HandleManager
@inject IContentManager ContentManager

Get by Content Item ID

string ContentId = await HandleManager.GetContentItemIdAsync("contentitemid:{id}");

Get by Alias

string ContentId = await HandleManager.GetContentItemIdAsync("alias:{alias}");

Get by Path

string ContentId = await HandleManager.GetContentItemIdAsync("/{path}");

Then get the content item using retrieved ID

ContentItem = await ContentManager.GetAsync(ContentId);

Question

Now, how to translate the obtained ContentItem to the desired culture/locale?

Short answer the content need to be localized

[lamualfa]

It's already localized. But by default, GetAsync method return en-US content item. How to change it to the desired culture/locale?

[hishamco]

The above extension methods are part of contents module which doesn't know anything about content localization

You could use ISession to fetch the localized version with the help of content localization index or simply you create a SQL query to do that. For last solution you could use Queries feature

After reading the documentation & the Orchard Core source code, this is my workaround. Is there any other methods to optimize this so we don't need to querying the content item twice?

@inject IContentHandleManager HandleManager
@inject IContentManager ContentManager
@inject OrchardCore.ContentLocalization.IContentLocalizationManager ContentLocalizationManager;

@code
{
  protected string? ContentId { get; set; }
  protected ContentItem? ContentItem { get; set; }

  protected override async Task OnParametersSetAsync()
  {
    @* Get Content ID *@
    ContentId = await HandleManager.GetContentItemIdAsync("alias:header");

    @* Get Content Item in the default culture *@
    ContentItem = await ContentManager.GetAsync(ContentId);

    @* Translate the Content Item to the desired culture *@
    ContentItem = await ContentLocalizationManager.LocalizeAsync(ContentItem, "id-ID");
  }
}
