"Order" has become a pretty overloaded term in this project. In the following commits, I introduce a few renames in hope to reduce various terminology confusions. This first commit renames the `/order` path operations to `/register`. I chose the term "register" because the page acts kind of like a cash register: the page presents various buttons to properly handle incoming order requests. This clears up the distinction between the register as a machine and order sessions as intermediate states.
Although we could say "place an order" to mean registering an order, "placement," in and of itself, does not have the notion of product orders. Yet, I have been using "placement" to mean registered orders. As such, I decided to rename "placement" to simply "order." This renaming revolves around mainly four things: - Path operations and Jinja macros - `placement_t` dictionary - SQLModel definitions - Database tables This commit addresses the first piece. Changes to path operation names are: - `s#/placements/(incoming|resolved)#/orders/&1#` - `s#/placed-items/incoming#/ordered-items/incoming#` - `s#/placements#/orders`
Constraint names are required to properly downgrade foreign key constraints: https://alembic.sqlalchemy.org/en/latest/naming.html In order to make Alembic migrations work in tandem with SQLModel, I had to modify the metadata object managed internally in the SQLModel namespace. The code is partially inspired by this comment (by the way, who's Dan?): https://www.github.com/fastapi/sqlmodel/issues/85#issuecomment-1380418653
I should have named these "orders" and "ordered_items" from the start. Also, "placement_id" and "placed_at" columns are renamed to "order_id" and "ordered_at," respectively. Alembic provides operations for renaming tables, columns, and constraints. That said, I had to write down the migration functions myself because Alembic does not recognize the previous name corresponds to the changed name so automatic script generation did not help much. The execution order is important, and very subtle. The lesson learned: renaming stringly-typed things is hard.

Closes #88
placement(s)という単語の使用を廃止し、完了した注文はこれからorder(s)を用います。"placement"という単語自体には注文の意味がなく、"place an order" というフレーズになって初めて注文の意味が現れます。このままだと混乱を招く可能性があります。そのため、元々注文ページのことを指すために使用していた"order" を "register"に言い換えることでorderを完了した注文に当てはめるよう命名を変更しました。以下、変更前の命名と変更後の命名の対応表です。
order（注文ページ）からregister(注文を受け付けるレジ) への命名変更:order(products, session)register(products, session)placement(s)(確定注文) からorder(s)(注文) への命名変更:incoming_placements(placements)incoming_orders(orders)resolved_placements(placements)resolved_orders(orders)placed_item(s)(確定したアイテム) からordered_item(s)(注文されたアイテム) への命名変更:placed_items_incoming(placed_items)ordered_items_incoming(ordered_items)
