Handle form_for in liveview

https://hexdocs.pm/phoenix_html/Phoenix.HTML.Form.html#module-phoenix-liveview-integration

<%= f = form_for @changeset, url, opts %>
  <%= text_input f, :name %>
</form>

The only way to fix it right now, it to replace <%= form_for %> with <form> and at the end replace it again with the original expression.

Other solution would be to add do at the end of form_for expression and replace </form> with <% end %> before encoding step. I actually prefer this, because it wouldn't require too many changes in encoder/decoder.

I was just coming to report this. I would be happy to help if I knew how to fix it. I'm trying to understand your other solution though. If I try to use a do block with the form I get a compile error: undefined function f/0

I've temporarily fixed it like this:

<% f = form_for @changeset, "#" %>
<form action="#" id="change_email_form" method="post" phx-submit="update_email">
  ...
</form>

I don't love it though.

I have a working solution, I need to wrap it up and release. Will try to do it today.
