[WIP] Allow multiple db_fields for a column in Djblets
Review Request #10241 — Created Oct. 18, 2018 and discarded
Some columns require multiple db_fields in order to properly query
and process the related data. One example of this is the fullname
column, which displays data from a user as a concatenation of their
firstname and lastname. Moving to allow multiple db_fields will make
some functionality easier, such as making the fullname column
sortable on the Users page.
