Duplicates in the search result can be removed using the distinct option like so:

@pagy, @discussions = pagy(@q.result(distinct: true))

Use target="_top" as shown in https://github.com/hotwired/turbo-rails/blob/main/app/helpers/turbo/frames_helper.rb:
<%= turbo_frame_tag "tray", src: tray_path(tray), target: "_top" %>
The issue is that Turbo Frames hijacks links as described quite well here: https://blog.cloud66.com/taking-rails-to-the-next-level-with-hotwire/

What is the thinking behind moving the javascript components back to the asset pipeline?

There is some initial unfamiliarity when switching to minitest, but in my experience this passes very quickly and minitest seems much more standard when you get used to it. Would not go back to rspec.

Hi Rino

One option is Andy Leverenz's https://justalever.com/work/hello-rails

You can also look at one of the Rails courses. This site gives an overview of some of them (note that these are on Rails 4 and Rails 5): https://digitaldefynd.com/best-ruby-on-rails-course-certification/.

A good Rails 6 basic course if the one from Pragmatic Studio but this costs a lot more: https://pragmaticstudio.com/rails.

Good luck with your studies.

Many thanks Chris. This tutorial is excellent.

This was due to erroneous check in a containing loop which caused a blank model name to be used in the eval. The code is fine.

Any idea why the following code :

<% model_set = instance_variable_set("@#{table_name}", eval("#{model_name}.all")) %>

produces this runtime error:

(eval):1: syntax error, unexpected '.'

The code correctly sets the instance variable @countries to the output from executing Country.all in the console or when using byebug (model_name is "Country" and table_name is "countries").

Should this be in a helper anyway?

Thanks in advance for assistance.

I have an error where the iframe is not being displayed. Clicking the Submit Payment button shows the Your card number is incomplete error message. I also see the error reported by Andrew. Looking at Stackoverflow there seem to be a number of current issues with Stripe and Turbolinks.
