+    Setting `strict: true` adds `STRICT_ALL_TABLES` to `sql_mode`. Setting
+    `strict: false` removes `STRICT_TRANS_TABLES`, `STRICT_ALL_TABLES`, and
+    `TRADITIONAL` from `sql_mode`.

+*   Limit record touching to once per transaction.

+        Message belongs_to :project, touch: true
+        Project belongs_to :account, touch: true

     has no explicit order defined.
