Ash.Query.filter is a macro

Important: You must require Ash.Query if you want to use Ash.Query.filter/2, as it is a macro.

If you see errors like the following:

Ash.Query.filter(MyResource, id == ^id)
error: misplaced operator ^id

The pin operator ^ is supported only inside matches or inside custom macros...

iex(3)> Ash.Query.filter(MyResource, something == true)
error: undefined variable "something"
└─ iex:3

You are very likely missing a require Ash.Query
