Trouble with relationships and form

I have the following:

    update :post_task do
      argument :task, :map do
        allow_nil? false
      end

      change manage_relationship(:task, :created_tasks, type: :create)
    end

    update :post_task do
      argument :task, :map do
        allow_nil? false
      end

      change manage_relationship(:task, :created_tasks, type: :create)
    end

and I want to have a form to post a task. What should the ash form init look like ? Currently I have

        socket.assigns.current_user |> AshPhoenix.Form.for_update(:post_task, as: "task")

        socket.assigns.current_user |> AshPhoenix.Form.for_update(:post_task, as: "task")

But this is giving me "task is required" error I'm sure I must be doing something wrong and it has to do with the form init. Could someone help ?

can you share the error, because I don't think it'scoming from that

This is my form for reference:

      <.form for={@form} id="task" phx-change="validate" phx-submit="save">
        <.input field={@form[:title]} type="text" label="Title" required />
        <.input field={@form[:price]} type="number" label="Price" required />
        <.input field={@form[:description]} type="textarea" label="Description" required />

        <.button phx-disable-with="Saving..." variant="primary">Save Task</.button>
        <.button navigate={return_path(@return_to, @task)}>Cancel</.button>
      </.form>

      <.form for={@form} id="task" phx-change="validate" phx-submit="save">
        <.input field={@form[:title]} type="text" label="Title" required />
        <.input field={@form[:price]} type="number" label="Price" required />
        <.input field={@form[:description]} type="textarea" label="Description" required />

        <.button phx-disable-with="Saving..." variant="primary">Save Task</.button>
        <.button navigate={return_path(@return_to, @task)}>Cancel</.button>
      </.form>

@Rebecca Le The error is "task is missing" "task is required" sorry, in the form errors

right, because your form doesn't have any task fields in it

QuentinOP•4mo ago

Should I use inputs_for ? It feels odd that I need to do a user update form when I'm trying to create a task

sevenseacat•4mo ago

indeed, that is kind of weird and I'm not sure why you'd do it that way usually you'd have a form to create a task and then use relate_actor to relate it to a user

QuentinOP•4mo ago

ah I never heard about relate_actor , maybe I'll check this out I kinda wanna understand how to make my setup work without it, though I'm mostly following the relationship docs in the ash docs what if my relationship isn't about the actor

sevenseacat•4mo ago

then yes, you'd probably use add_form to add a task form to the parent form, and use inputs_for to iterate over the (one) task and render fields for it

QuentinOP•4mo ago

okay cool, I think I'm missing the add_form part
