I would like to setup a nested form using a map. The form_for and to_form accept a map and this works for a single level form. %{"name" => "fred"} |> Phoenix.Component.to_form() # this works and allows editing the name field using html form. but would I expect the following to work? %{"name" => "…

Have you tried setting up addresses as embeds together with Phoenix.Component.inputs_for/1 within the form in the template?

I don’t have a Ecto schema for this, so not sure if embeds apply. I am trying to use the input_for and so far have not been able to get very far. Latest error I get is: * (ArgumentError) the Access calls for keywords expect the key to be an atom, got: "_persistent_id" (elixir 1.14.3) lib/access…

That‘s not true. It doesn‘t care for ecto. It requires a working Phoenix.HTML.FormData protocol implementation just like all other phoenix form APIs. The implementation for ecto certainly includes a lot of bells and whistles and I wouldn‘t call the map based implementation to be „feature complete“, …

[image] LostKobrakai: It requires a working Phoenix.HTML.FormData protocol implementation just like all other phoenix form APIs. Yup, good catch! To re-clarify, to_form/1 accepts either Ecto changesets or maps and converts them into a Phoenix.HTML.Form struct. And inputs_for/1 requires a Ph…
