In Active Record internal, `arel_table` is not directly used but `arel_attribute` is used, since `arel_table` doesn't normalize an attribute name as a string, and doesn't resolve attribute aliases. For the above reason, `arel_attribute` should be used rather than `arel_table`, but most people directly use `arel_table`, both `arel_table` and `arel_attribute` are private API though. Although I'd not recommend using private API, `arel_table` is actually widely used, and it is also problematic for unscopeable queries and hash-like relation merging friendly, as I explained at #39863. To resolve the issue, this change moves Arel attribute normalization (attribute name as a string, and attribute alias resolution) into `arel_table`. |
