180

[RAprogramm]

Closes #180.

#[auto] fields were included in generated INSERTs with Default::default() values — created_at: DateTime<Utc> wrote an explicit 1970-01-01, silently clobbering the table's DEFAULT now(). Found while validating the crate against a real backend.

Fix

• Context now carries separate columns_str (SELECT, all columns) and insert_columns_str/placeholders (INSERT, minus #[auto])
• Insertable struct, insert bindings and Entity→Insertable mappers skip auto fields; DB defaults apply and persisted values come back via RETURNING * (the default)
• All insert paths updated: create (all returning modes), create_many, upsert, aggregate-root save, transaction adapter
• Upsert DO UPDATE SET also stops overwriting auto columns (previously reset created_at on the update path)
• With returning = "id"/"none"/custom the returned pre-built entity still carries placeholder auto values — unchanged semantics, now documented by the column split

Testing

• 2 new unit tests pinning the insert column shape — 677 total green
• clippy --all-targets -D warnings clean, all-features suite green, deny ok
