Reference field computed index field in multiple language

Question

My sitecore item contains dropdown for City, state, category etc. It's all in multiple languages but on sitecore item dropdown, it's appearing in english only. I've created computed index field for all referenced dropdown. It's indexing only english language content for all languages. Below is my code to get refernce field.

 internal static Item GetTargetItemsFromField(this Item item, ID fieldId)
    {
        if (item.Fields.Contains(fieldId))
        {
            ReferenceField field = item.Fields[fieldId];
            if (field != null && field.TargetItem != null)
            {
                return field.TargetItem;
            }
        }

        return null;
    }

Debug mode:

Code is working fine but this code (item.Fields[fieldId]) return english language always. So it's indexing english content only.

I am using below code for language in config file:

 <field fieldName="_language" 
        storageType="YES" 
        indexType="TOKENIZED"    
        vectorType="NO" 
        boost="1f" 
        type="System.String"
        settingType="Sitecore.ContentSearch.LuceneProvider.LuceneSearchFieldConfiguration, Sitecore.ContentSearch.LuceneProvider">
              <analyzer type="Sitecore.ContentSearch.LuceneProvider.Analyzers.LowerCaseKeywordAnalyzer, Sitecore.ContentSearch.LuceneProvider" />
  </field>

As per luke output it's indexing only english content for all other language.

How to fix this code to return all language content?

Answer 1

The request for the targetitem does not take into account the language of the item the field is on:

public Item TargetItem
{
  get
  {
    return this.Database.Items[this.Path];
  }
}

This means that it just uses the context language. Your computed index field code is run in the context of an index update, and that will be in an English context. To solve your issue you could use a LanguageSwitcher. You can find some information here: https://ctor.io/correctly-switching-sitecore-contextes/ but you actually just need a using statement around the code:

using (new Sitecore.Globalization.LanguageSwitcher(item.Language.Name))
{
    ...
}
