语言后备/在 Sitecore.Globalization.Translate.TextByLanguage(key, language) 中设置语言；？

Question

我正在使用 Language Fallback 提供程序。这似乎对存储在 System > Dictionary 中的项目没有任何影响。

我希望它回退到 Language 项的“Fallback”属性中指定的语言。

更糟糕的情况，我想回退到英语。

我从字典中获取文本的方法可以调用它。

Globalization.Translate.TextByLanguage(key, ????);

我被困住了：

1. 如何找到当前指定语言的“Fallback”属性值
2. 如何将它传递给 TextByLanguage。它似乎需要一个 Language 属性，但 Language 似乎没有 任何构造函数。

历史：按照@Jammykam 的建议，我查看了 Verndale 示例，但我的运气为零。它似乎从来没有开过火。

我在我的解决方案中添加了以下类：

using Sitecore.Diagnostics;
using Sitecore.Globalization;
using Sitecore.Pipelines.GetTranslation;
using Sitecore.SharedSource.PartialLanguageFallback.Extensions;
using System;
using System.Collections.Generic;

namespace Sitecore.Web.Pipelines
{
    public class DictionaryFallback : TryGetFromFallbackDomains
    {
        public static bool EnableFallback
        {
            get
            {
                return Sitecore.Context.Site != null &&
                       Sitecore.Context.Site.SiteInfo.Properties["enableFallback"] != null &&
                       Sitecore.Context.Site.SiteInfo.Properties["enableFallback"].Equals("true", StringComparison.InvariantCultureIgnoreCase);
            }
        }

        /// <summary>
        /// Runs the processor.
        /// 
        /// </summary>
        /// <param name="args">The arguments.
        ///             </param>
        public void Process(GetTranslationArgs args)
        {
            Assert.ArgumentNotNull((object)args, "args");
            List<string> processedDomains = new List<string>();
            if (args.HasResult || Context.Site == null || string.IsNullOrEmpty(Context.Site.DictionaryDomain))
                return;
            this.Args = args;
            this.Database = args.Options.Database ?? args.ContentDatabase;
            DictionaryDomain domain;
            if (!DictionaryDomain.TryParse(Context.Site.DictionaryDomain, this.Database, out domain) || domain == null) {
                Log.Info("Error Parsing Dictionary: " + domain.FullyQualifiedName, this);
                return;
            }


            string result;
            if (this.TryGetTranslation(domain, processedDomains, out result) && result != null)
            {
                Log.Info("Normal Translation: " + domain.FullyQualifiedName + ": " + result, this);
                args.Result = result;
            }
            else if (EnableFallback)
            {
                if (this.TryTranslateTextByFallbackLanguage(args, domain, out result) && result != null)
                {
                    Log.Info("Fallback Translation: " + domain.FullyQualifiedName + ": " + result, this);
                    args.Result = result;
                }
            }

        }

        protected virtual bool TryTranslateTextByFallbackLanguage(GetTranslationArgs args, DictionaryDomain domain, out string result)
        {
            result = null;
            List<string> processedDomains = new List<string>();

            // check if the the language passed in with the args has fallback assigned
            // if so, then get that fallback language
            // must try to get the translation based on that language
            var languageFallsBack = args.Language.HasFallbackAssigned(args.ContentDatabase);
            if (languageFallsBack)
            {
                Language fallbackLanguage = args.Language.GetFallbackLanguage(args.ContentDatabase);

                // the following cannot be called from here, because it is an internal method to the Sitecore.Kernel library
                //Translate.TryTranslateTextByLanguage(args.Key, domain, fallbackLanguage, out result, args.Parameters);

                // therefore, we set Args.Language to the fallbacklanguage
                // this.Args is the Args object in TryGetFromFallbackDomains processor
                // then we call this.TryGetTranslation, which is a method in the TryGetFromFallbackDomains processor, 
                // which IS in the Sitecore.Kernel library and therefore can make the call to TryTranslateTextByLanguage

                this.Args.Language = fallbackLanguage;

                if (this.TryGetTranslation(domain, processedDomains, out result) && result != null)
                {
                    return true;
                }
                else
                {
                    // if no results if found, try to see if this fallback language falls back itself to another language
                    // and then if so, try the translation with that
                    // pass into the recursive call this.Args (instead of args), since the language has been updated in this.Args
                    if (result == null)
                    {
                        var isSuccess = TryTranslateTextByFallbackLanguage(this.Args, domain, out result);
                        return isSuccess;
                    }
                    else
                        return false;
                }
            }
            else
            {
                return false;
            }

        }


    }
}

我在补丁文件中添加了以下代码：

<pipelines>
            <getTranslation>
                <processor patch:after="*[@type='Sitecore.Pipelines.GetTranslation.TryGetFromCoreDatabase, Sitecore.Kernel']" type="Sitecore.Web.Pipelines.DictionaryFallback, Sitecore.Web" />
            </getTranslation>
        </pipelines>

我可以使用 showconfig.aspx 看到它：

<getTranslation>
<processor type="Sitecore.Pipelines.GetTranslation.ResolveContentDatabase, Sitecore.Kernel"/>
<processor type="Sitecore.Pipelines.GetTranslation.TryGetFromDomain, Sitecore.Kernel"/>
<processor type="Sitecore.Pipelines.GetTranslation.TryGetFromFallbackDomains, Sitecore.Kernel"/>
<processor type="Sitecore.Pipelines.GetTranslation.TryGetFromSiteDomain, Sitecore.Kernel"/>
<processor type="Sitecore.Pipelines.GetTranslation.TryGetFromContextDatabase, Sitecore.Kernel"/>
<processor type="Sitecore.Pipelines.GetTranslation.TryGetFromCoreDatabase, Sitecore.Kernel"/>
<processor type="Sitecore.Web.Pipelines.DictionaryFallback, Sitecore.Web" patch:source="SitecoreSettings.config"/>
</getTranslation>

您会在我的课堂上看到我投入了一些日志记录，但我从未看到记录的项目。具有所选语言版本的项目正确呈现。但如果他们没有版本，它会显示密钥而不是后退。

关闭更新：我使用了下面接受的答案并对其进行了修改以适合我：https://gist.github.com/eat-sleep-code/0ea3f1bd2be19bbf9fc6

Answer 1

我已经解决了这个问题，请查看以下博客文章，与字典项相关的部分：

Dictionary Items Language Fallback

我还为此构建了一个模块，上传到 sitecore 仍在等待审核。

Answer 2

默认情况下，字典项不适用于语言后备模块，您必须使用额外的处理器修补 getTranslate 管道，以进行后备语言检查并在后备语言中获取正确的字典项。

您可以在本文中找到有关Using Fallback with the Dictionary 的更多详细信息，之后您可以继续正常使用字典，而无需通过Globalization.Translate.TextByLanguage(key) 的语言。
