+Hi,
+
+i copied from
+`03_source/cms_backend/src/app/api/party-event`
+to
+`03_source/cms_backend/src/app/api/party-order`
+
+with knowledge in `schema.prisma` file, and take a look into the sibling files in the same directory.
+
+i want you to update `03_source/cms_backend/src/app/api/party-order` content to handle `party-order` (the purchase order of the party)
+`party-order.service.ts` is already prepared and you can use it
+please maintain same format and level of detail when you edit.
+
+thanks.
