Access queryKey in mutation's queryFn?

[geekox86]

Greetings,

I can access queryKey in queries' queryFn with no problem. But, I am not sure how to do so from within mutations' queryFn.

Plz, help.

mutations don't support that.

Is there a fundamental reason for this? Maybe I am missing something I am missing about mutations?

What issue are you trying to solve?

[geekox86]

I am trying to feed a mutation function's parameters from its mutation key declaratively, just like queries.

The mutation key is a vue reactive with some computed parts that are used in the parameter feeding.

Because I do not want to pass the parameters imperatively with every call to mutate.

Mutations are fundamentally different from queries because they run on demand, not automatically.You can call mutate multiple times with different values, too.

so either pass your value to .mutate or to useMutation itself and access it from the closure.
