MongoDB只有一个项目，发布还是放置？

Question

POST to create a new item, PUT to update an item.. but what if there's only one item in the database?

Do I code: 'if item already exists, find it and PUT' else 'POST'

or am I missing something very obvious?

I briefly thought of doing post everytime, and on the first line of the post just delete everything, then post, but that seems dumb

Answer 1

Personally, I prefer to POST for the original creation, and PATCH for updates...

If you have the id, or can generate it on the client (such as a uuid):

PUT /myresources/:id

If you don't have the id, or need to generate it on the server:

POST /myresources

should return a location header with the generated path, as well as an acceptable response body.

{
  id: "someid",
  location: "/myresources/someid"
}
