Hello, I’m trying to create a form but my form use a changeset with embeed schema like:

%{
  name: "Name",
  address:  %{
    name: "Street Alpha",
    number: 412
    postal_code: 12312321
  }
}

How to do the same without input_for like 1.6 version? Thank you.

yeah strange I have the same issue here, actually ist should come from Phoenix.HTML right? seems like no functions from this module are available somehow

ok its from Phoenix.HTML.Form, so you can

import Phoenix.HTML.Form

e.g. in MyAppWeb.html_helpers

Hmmm Ok. But I understood that we should use components from core_components.ex where it’s all components now.
I don’t know if we should continue using this Phoenix.HTML

Did you ever manage to figure out how to use inputs_for with the new core components? I’m trying to follow the Contexts guide for 1.7.0-rc.2 and I’m having a hard time to make it work.

Do we still need to use Phoenix.HTML.Form.inputs_for and <.form /> or is there another way of doing it with the simple_form component?

Okay, I think I got it. Not sure if this is the best way but I made it work using core components:

<.simple_form :let={f} for={@changeset} action={~p"/cart"}>
  <ul>
    <li :for={item_form <- inputs_for(f, :items)}>
      <% item = item_form.data %>
      <%= hidden_inputs_for(item_form) %>
      <%= item.product.title %>
      <.input field={{item_form, :quantity}} type="number" label="Quantity" />
      <%= currency_to_str(ShoppingCart.total_item_price(item)) %>
    </li>
  </ul>

  <:actions>
    <.button>update cart</.button>
  </:actions>
</.simple_form>
