Create associated record

[manuelmeurer]

I have a "A has_one B" association, and on the "show B" view, I want to click on a link to get to the "new A" form with the B selected.
For example, I'm viewing a user invite and I want to create a user for this invite.
How would I do that in Avo?

In the docs there is an explanation on how to make the has_one field visible in the "edit" view, but nothing about the "new" view.
Is that on purpose?

Hi @manuelmeurer, this discussion slipped under the radar. Thank you for your patience.

I can think of some solutions, but none are plug and play. Before we dive in, could you please confirm if this question is still relevant for your case or if you already found and applied a solution?

You can use nested on the new view. Check the docs about it here https://docs.avohq.io/3.0/associations/has_one.html#nested-in-forms

I've solved it like this:

def render_avo_button(
  url_or_action,
  icon:,
  title:,
  resource: nil)

  url, data =
    case url_or_action
    when Class
      unless url_or_action < Avo::BaseAction
        raise "Expected an Avo Action class, got #{url_or_action}"
      end
      url_or_action.link_arguments(resource: resource || self.resource)
    when String
      [url_or_action, {}]
    else raise "Unexpected URL or action: #{url_or_action.class}"
    end

  data[:tippy] = :tooltip
  render Avo::ButtonComponent.new(
    url,
    icon:,
    title:,
    data:,
    style:   :outline,
    color:   :blue,
    size:    :xs,
    is_link: true
  )
end

render_avo_button(
  avo.new_resources_message_path(recipient_gid: record.to_gid.to_s),
  icon:  "heroicons/outline/envelope",
  title: "New Message"
)

This lets me render buttons to random URLs or even existing actions.
The message resource has:

field :recipient, as: :belongs_to, default: params[:recipient_gid]&.then { GlobalID.find(it) }
