Hey, I can't make a new durable object :

Cannot create binding for class 'Trainer' because it is not currently configured to implement durable objects. Did you forget to apply a --new-class migration to it? [code: 10061]

Cannot create binding for class 'Trainer' because it is not currently configured to implement durable objects. Did you forget to apply a --new-class migration to it? [code: 10061]

But if I try to add it

npx wrangler deploy --new-class Trainer
✘ [ERROR] Unknown arguments: new-class, newClass

npx wrangler deploy --new-class Trainer
✘ [ERROR] Unknown arguments: new-class, newClass

In my wrangler I have

[[durable_objects.bindings]]
name = "DURABLE_TRAINER"
class_name = "Trainer"
[[migrations]]
tag = "v1"
new_classes = ["Trainer"]

[[durable_objects.bindings]]
name = "DURABLE_TRAINER"
class_name = "Trainer"
[[migrations]]
tag = "v1"
new_classes = ["Trainer"]

I already did it once and then I deleted my durable object via dashboard, how to remake one ?

Try just running wrangler deploy

Use a different tag, for example tag = “v1.1”

Thanks but I have read all the materials you guys provided. The reason why doing this is to remove errors. I understand that. But what I am saying is that only one read should not consume this number of read because it does not make sense to scan other tables when I just want to get one row. FYI, there is no foreign key in every 8 tables and there are only 6 records in total I will try researching good indices anyway. Thanks for the answer.

Cool 😎 thank you for the info!

Just an addendum here in case anyone sees this in the future that this is for typing only - if the row isn't actually a User no error will be thrown, it will show as a User to Typescript but not actually be a User object 😄

Hi guys, Is the latency between the Worker and the Durable object expected to be around 100-160ms provided that they both are in the same location?

Does write coalescing apply to SQLite storage? I'm particularly worried about the atomicity described in the docs (and quoted below) for non-SQL storage.

If you invoke put() (or delete()) multiple times without performing any await in the meantime, the operations will automatically be combined and submitted atomically. In case of a machine failure, either all of the writes will have been stored to disk or none of the writes will have been stored to disk.

Hello, I’m Allie!•7mo ago

AFAIK, no, but it doesn’t have to, since the storage is synchronous anyway
