Render comments outside of resource show

[kochis]

I can't seem to find a way to render the ActiveAdmin comments outside of the show action. Is this even possible?

I've tried calling the active_admin_comments method directly on ActiveAdmin::Comments::ShowPageHelper, but can't seem to get it to work.

What I'm trying to do is render the comments in the view from a member_action method. Is there perhaps a better way to do this?

I think this should work:

  ActiveAdmin::Comments::Views::Comments.active_admin_comments_for(@your_resource)

I tried that in both view, and controller methods, and got an undefined method error. I think this tends to be an issue when calling this method outside the context of the ActiveAdmin show method.

Arbre components can only be rendered within an Arbre context. The blocks for member_action and collection_action run directly within the controller and do not provide a context for Arbre components. It is possible to render an Arbre view template such as custom_action.html.arb and within that template active_admin_comments_for(resource) is available.

# custom_action.html.arb
active_admin_comments_for(resource)

A second method is to create an Arbre::Context within the view rendered by another template language like ERB.

<h2>Custom Action ERB</h2>
<%= 
  Arbre::Context.new({}, self) do
    active_admin_comments_for(resource)
  end
%>

This method works for all Arbre components provided by ActiveAdmin. See Arbre::Context for more information.

Thanks @zorab47, that was able to solve my issue 👍

Thank you very much for this hint!

I've tried to use this advice and finally comments are shown just once on the page, but at the same time comments addition form is missing.

Could you advice me, how to fix this?

@BRZInc I assume you try to add the comments form to the edit view. That will not work since you cant put a form into a form. The edit view looks like this with (not working) the comments form:

form do |f| 
  # form fields
  active_admin_comments_for(resource)
end

You will see the comments and the form but not the comments form will be submitted but the whole resource form.

If you just want to see the comments, you can recreate the comments by yourself without creating a form:

form do |f|
  # form fields

  panel "Comments", class: 'comments player panel' do
    ActiveAdmin::Comment.where(resource_id: params[:id]).each do |comment|
      admin = AdminUser.find(comment.author_id)
      div class: 'active_admin_comment' do
        div class: 'active_admin_comment_meta' do
          h4 class: 'active_admin_comment_author' do
            a admin.email, href: admin_admin_user_path(comment.author_id)
          end
          span l admin.created_at
        end
        div class: 'active_admin_comment_body' do
          text_node "<p>#{comment.body}</p>".html_safe
        end
      end
    end

    text_node "#{button_to 'Neuer Kommentar', edit_admin_player_path(player.id)}".html_safe
  end
end

You could also take the result from active_admin_comments_for(resource) and throw away the form in the string. But that's fishy imho.

EDIT: see the next two comments ...

@andywenk I think don't need the join.html_safe and you can use each

[andywenk]

@timoschilling yup you are right - that was still the code when I debugged the values without creating any HTML. Updated my comment. Thanks!
