Using Mutations API to populate a field in Sanity Studio

Last updated: Jan 6, 2022
Hey folks! I have a new field in Sanity Studio and I forgot to add an initial value for it...Is there a way for me to populate that field through the command lines for my hundreds of entries?

There is! You can use the Mutations API .

The weird thing is that I deployed with these initial values
initialValue: {
    saved: false,
    ash:3
  }

My field is in studio but the initial value is not...

In this situation, you wouldn't use
initialValue
. You would directly set the field. So, it would be something like:
{
  "saved": "false",
  "ash": "3"
}

You mean if I want to use Mutation?

But I would like to understand what I missed when deploying my schema.

Correct. Am I misinterpreting that second question 😅 ?

Sorry, I have been coding for the last 15 hours my brain is fried.
Jan 6, 2022, 12:36 AM
Could you please confirm that I used 'initialValue' properly in this case?
Jan 6, 2022, 12:36 AM
OK, cool. Thanks for that. Yes, that looks correct. That initial value would show up in a newly created document.
Jan 6, 2022, 12:38 AM
Ok.
Jan 6, 2022, 12:38 AM
Make sense. I deployed before the inital value.
Jan 6, 2022, 12:38 AM
So now I need to patch everything.
Jan 6, 2022, 12:39 AM
Thank you Rachael.
Jan 6, 2022, 12:39 AM
Appreciate the patience 🙂
Jan 6, 2022, 12:39 AM
For sure! Let me know if it's not working as intended!
Jan 6, 2022, 12:39 AM
Of course. Thanks.
