Form.datetime_select/3 builder example uses deprecated `~e` sigil

[Michał Łępicki]

https://hexdocs.pm/phoenix_html/3.1.0/Phoenix.HTML.Form.html#datetime_select/3-builder
The def my_datetime_select example should probably use a ~H sigil?

@michallepicki can you please check if it works with ~H, and if it does, send a PR? Thank you.

[Michał Łępicki]

@michallepicki sorry, I couldn't figure it out, I settled on html_escape for my use case for now (I'm using it in a regular dead view)

[José Valim]

Did you get an error or something?

  def my_datetime_select(form, field, opts \\ []) do
    builder = fn b ->
      ~H"""
      Date: <%= b.(:day, []) %> / <%= b.(:month, []) %> / <%= b.(:year, []) %>
      Time: <%= b.(:hour, []) %> : <%= b.(:minute, []) %>
      """
    end

    datetime_select(form, field, [builder: builder] ++ opts)
  end

Maybe this needs to be a functional Phoenix.Component? Not sure how/if that would work, I don't have experience with them yet

[José Valim]

you always need an assigns attribute before, something like this would work:

assigns = %{b: b}

~H"""
"""

and then you use @b inside.
