0:00 Now, when we did this call here,
0:02 we did this post. We passed some data that was in the body.
0:05 It created this entity over here and everything worked.
0:09 So what did FastAPI do? It said "great,
0:11 everything worked. 200 ok". But let's drop over on our again
0:17 and see about these success codes. So Okay,
0:20 well, that's kind of the most generic term.
0:22 And here's a representation of the resource.
0:24 We actually did give that back, so
0:26 it's kind of okay. But what would make more sense would be created. Over
0:31 here, we're creating a new thing,
0:33 we've accepted their data. It was all good.
0:36 And we could either give them a location where it was created or something that describes
0:41 it. And what we're doing to describe it here is this is you know,
0:43 theoretically an ID You could do a lookup on in a database or some
0:47 other API right? That's the idea,
0:49 we're not fully fledged in this out.
0:51 But a 201 created makes a lot more sense than 200.
0:54 So does that mean we've got to go
0:56 write more complicated code instead of just doing this?
0:58 We've got a create a response and set all the information about it?
1:02 No. Just like this little name up here,
1:04 we could just say "status code equals 201".
1:06 So if everything goes okay, that's what's getting submitted, or returned.
1:11 Otherwise, it's whatever you explicitly set.
1:13 So like we would up here,
1:15 you know, 400 or 500 or whatever.
1:17 Let's just submit this again. Boom.
1:20 Check it out. 201
1:21 created. The request has been fulfilled and resulted in a new resource being created.
1:25 And guess what? That new resource
1:26 was returned as well. Awesome.
1:28 Now we're playing nice with status codes.
