Revision history for DBIx::Class::Schema::GraphQL

v0.0.2  2026-06-08
        [New Features]
        - Added patchX mutations for every source alongside the existing
          updateX. patchX performs a sparse (partial) update: only the
          non-key columns explicitly supplied by the caller are written to
          the database; all omitted columns are left exactly as they are.
          The lookup mechanism (primary key or any declared unique
          constraint) is identical to updateX.

          Example:
           # change only the title - author_id is untouched
           mutation { patchBook(id: 1, title: "Dune Messiah") { id title } }

        [Behaviour Changes]
        - updateX description updated to clarify it is a full update and to
          direct callers toward patchX when sparse intent is deliberate.
          The resolver itself is unchanged; this is a documentation
          clarification only.

        [Error Handling]
        - patchX dies with a descriptive message ("patchX: no non-key columns
          supplied - nothing to update") when the caller provides only key
          columns and no data columns. The error surfaces in the top-level
          GraphQL errors array; the database is not touched.

        [Tests]
        - t/04-mutations.t: added six new test blocks covering patchX:
          * patchAuthor - single column patched, sibling column verified
            untouched in-both the GraphQL response and the database
          * patchAuthor - patch the other column, first column verified intact
          * patchAuthor - lookup by unique constraint
          * patchAuthor - unknown row surfaces in errors array
          * patchAuthor - no non-key columns supplied raises an error and
            leaves the database row unchanged
          * patchBook - patch a Float column (price) on a second source,
            title verified untouched; confirms patchX generation is correct
            across all sources, not only the seed source

        [Documentation]
        - MUTATIONS section: patchX documented with description, example,
          and behaviour notes. updateX example updated to show a
          full-column call.
        - DESCRIPTION: patchX added to the list of generated mutation entry
          points.
        - LIMITATIONS: "updateX is a full update" bullet updated to reference
          patchX as the supported path for partial updates.
        - SYNOPSIS: patchX example added.

v0.0.1  2026-06-07
        - First draft released.
