The question I want to ask is this: How does knockout data binding work in Magento 2.3.5?
I have migrated data from Magento 22.214.171.124 using Magento Data Migration Tool.
The backend Catalog -> Categories -> (any category) does not pull the data from the database. It seems the values are just defaults.
SELECT block.content, eea.attribute_code, eea.attribute_id, cat.*, ccet.*, block.* FROM catalog_category_entity_int ccet INNER JOIN catalog_category_entity AS cat ON ccet.entity_id = cat.entity_id INNER JOIN eav_attribute eea ON ccet.attribute_id = eea.attribute_id INNER JOIN cms_block as block ON block.block_id = ccet.value WHERE eea.attribute_code = 'landing_page' AND ccet.entity_id = 7 ORDER BY eea.attribute_code ASC;
The results of the database data for ID 7 (as image above):
The query I ran targets
landing_page attribute (all other attributes and categories have same issue as discussed here), which returns
brands-landing-page (this is the correct item) and all other information - Brands category with Brands Landing Page.
The data-binding (or something else) does not work correctly. This means I cannot save the Category, (as Category Name is EMPTY but required).
How and where can I start to investigate what is wrong, how will I be able if Knockout (or PHP that populates the data and binds to Knockout) works correctly?
Frontend also doesn't display the landing page for the categories where set.
- Most important thing - Data is migrated using
data-migration-tool:2.3.5from Magento 126.96.36.199
- The landing pages also doesn't show on the frontend (same issue with bindings maybe?)
- No errors in log files, no errors displayed on page, or browser console
- I have two Store IDs -
1 custom storeChanging Store IDs from 0 to 1 has no effect!
My instance was 100% related to
data-migration-tool that doesn't correctly update all the related tables. See LitExtension Magento Migration or my answer below for tables involved.
