Select on nested form raises ArgumentError

[rgraff]

Using select(conn, "Users", from: "Metric") will error on fields generated with <inputs_for .../>

     ** (ArgumentError) value for hidden "automation[trigger][_touched]" must be one of ["_form_type,_persistent_id,_touched,name,type"], got: "name,type"
    code: |> select(metric.name, from: "Metric")
    stacktrace:
      (phoenix_live_view 0.20.17) lib/phoenix_live_view/test/live_view_test.ex:1102: Phoenix.LiveViewTest.call/2
      (phoenix_test 0.3.1) lib/phoenix_test/live.ex:219: PhoenixTest.Live.fill_form/3

It works with <inputs_for skip_hidden={true} .../>

Thanks for opening the issue @rgraff!

Any chance you could include some code that makes this easy to reproduce?

[rgraff]

Unfortunately, I can't reproduce the error in the test suite. I'm not exactly sure what happens with <.inputs_for .../> so I'm not confident my test setup is correct.

@rgraff can you use reproduce the error in a sample Phoenix app that you can share with us? Would that be easier than trying to add a test in phoenix_test?

[rgraff]

@germsvel yes, I will do that in the next couple weeks. Have a deadline right now and have worked-around this issue for now.

Excellent! 👍 Glad to hear it's not blocking you
