问题
I have existing category hierarchy with parent_id column. I have configured Gedmo Tree extension and update schema. I can see 'level' column is added to category table and category_closure table is created.
How do I populate the data in category_closure table. There are no
$repo->verify();
$repo->recover();
methods for ClosureTreeRepository. I have tried updating category records so that to trigger TreeListener but still there is no data in category_closure.
How do I populate hierarchy in category_closure table ?
回答1:
Methods verify and recover are available in 3.0.x-dev version.
You are supposed to populate closure data on your own.
