Slug Generating Document Action - How to Invalidate Fields or Display an Error

I am improving my

slug

generating document action, which replaces the default publish action. Can someone help me understand what my options are for invalidating fields or displaying an error, and then aborting a publish from within my custom publish action? Is there a place in the documentation where I may have missed this? Thanks!

Does this help? https://www.sanity.io/docs/validation#fcadf15930b3 looks like validation isn't very feature rich at the moment. There is a validateDocument function in sanity if you search GitHub though.

, I don't think that helps, unfortunately.
I am trying to ensure that the slug I am setting will be unique and I am doing that within the publish action. I would expect there to be a way to "cancel" or "abort" the publish action.

So your slug has a unique validation on it and when you patch it the document still gets saved?

in my document action, I can choose to publish the document or not. I'm choosing not to, when the slug is not unique. It is at that point that I'd like to send a message to the UI stating why the document cannot be published.

If you throw an error does it appear in a red box near the publish button? somehow the intl-input plugin does it when the doc references another one like that.

This enforced document linking and shows an error after the attempted action https://github.com/LiamMartens/sanity-plugin-intl-input

I will look into that plugin, if I throw an error I see it in the console but not in a popup of any kind.

Ah ok. Wonder if you need to push to the toast module in sanity?

Ill try it out myself on Monday as I'm interested now.

hmmm. I like the idea of using a toast. I just don't know how to get access to the

toast

object to push a new message to. Maybe I'm misunderstanding the docs.

Should be able to use the hook and call it.

Got it, thanks again !
