Hey guys, I've been checking out convex. I managed to do auth, get and post operations.
But I can't seem to find docs on how to delete an item from a table. I've attached the type error I'm getting. I'm also attaching the post mutation which works fine.
If there're docs for this, please point me to them, thanks!

hey @vivid viper ! thanks for trying convex
ids are database-unique. every id is the only id with that value in the whole database, not just for the table
in fact, ids embed information in them that lets convex know which table the id came from
so, the delete method doesn't need the table name. only the id. https://docs.convex.dev/api/interfaces/server.DatabaseWriter#delete
if you remove the 'decisions' argument from that method, everything should work

hi Jamie, thanks for the fast response, that's what I initially tried, but I get this type error:
am I missing something?

id isn't a v.string(), it's a v.id('table-name') . see example here: https://github.com/get-convex/convex-demos/blob/c0d84a85e533ed6fdf8a83f9469d88709335bbb0/relational-data-modeling/README.md?plain=1#L23
in your case I suppose it's a v.id('decisions')
this just gives you even more type safety that you're actually passing an id from the proper table into your convex functions

yooo, it works! Thanks for help Jamie. Keep up the great work!

glad to hear it!

The docs for delete are here, including validator example:
https://docs.convex.dev/database/writing-data#deleting-documents
Let us know if you had trouble finding this with the docs search.

hi @indigo thicket thanks for the docs link!
one thing that took me a bit of time to get used to is that in convex folder I have to reference type with "v", and in the app code I have to import them _generated/dataModel.
I think I saw it somewhere else in the docs, but not in the delete. Anyways, still a really cool product I love the analytics dashboard. This makes feel cloud function development achievable for mortals, I've been having a lot of fun 😄

in fact, ids embed information in them that lets convex know which table the id ...
is there a way for us to know this too? Having an id and knowing which table it comes from
