Attribute Index Fix

Magento 2 supports custom source models for attributes except for indexing them into the catalog_product_index_eav table (which feeds layered navigation)., _(*1)

The original problem is found in \Magento\Catalog\Model\ResourceModel\Product\Indexer\Eav\Source:302 where it ensures that the values saved exist in the eav_attribute_option table. When using that custom source model, those values do not exist., _(*2)

The first / easy solution is to comment out those lines. That doesn't work for production so a more durable method needs to be had. While using a preference is not preferrable, this will solve the problem in the short term., _(*3)

After some research and many hours spent, I found that @maderlock has a good fix: https://github.com/magento/magento2/issues/417#issuecomment-265146285, _(*4)

Here is how to get this running:, _(*5)

• composer require swiftotter/attribute-index-fix
• php bin/magento module:enable SwiftOtter_AttributeIndexFix
• php bin/magento cache:clean
