Array field ids

[yamila-fraiman]

Hello, in the doc says that keyName will be removed in the next major version. How will it work? Using always id? Without ids?

Thank you.

you won't need to change keyName prop anymore, field array will return id for each input group and not be part of your submission data.

Thank you. Will it be part of fields array? Because I have my own id and actually I am using uuid as keyName to prevent overriding my mongodb id

Will it still override existing id properties in arrays?

@bluebill1049 I can see that in the latest version keyName should not be needed and IDs are handled automatically, but it doesn't seem to work for me. I've created a code sandbox to show the issue:

https://codesandbox.io/s/wispy-https-8y2uuo?file=/src/App.tsx:936-953

So if I don't specify keyName in FieldArray, my ids are overridden, but at the same time typescript doesn't seem to accept anything else than id as a value for keyName. Am I missing something?

EDIT: for anyone else wondering, it seems like bringing back original IDs happens in handleSubmit, which misled me. I am doing some transformations before sending my data to the API but I've done that too early when the id property stores form keys still.

Please use getValues() method or data object returned from on valid callback of handleSubmit(onValid) from useForm hook to get current form values.

The documentation of fields object from useFieldArray hook already described clearly that it only contains default value and key for React component, not the current field array value.
