The debugger you using in top of page is that scout apm ? 

It’s Rack Mini Profiler and comes standard by default with Rails 6.1.

What is 'Flaky' means in 16:23?

Sorry, my English is not so good.

'Flaky' is like 'unreliable.' Something you can't depend on to work properly 100% of the time.

Exactly. I wouldn't expect the form field to be nested within the canvas since the "tag" is not a block enclosing the form field. 

Hi David, can I ask how did you implement the "Code" section besides the "Comment" area? It's perfect to show the file structure and code. Did you use a gem? 

  jackc97  It was a custom solution. I have a gitlab server which hosts the files and this site communicates to the gitlab server via their open API. I basically then list out the files and folders and display whichever file that was clicked on.

Hello there, i'm a junior developer, i would like create a search by scan qr code, i created the barcode for each pets (in my case) but i don't how can create a search in the index method, can someone help me and thanks...

actually my problem is how can i use the camera on the index method??

 <%= form.label :name %>
  <%= content_tag :div, 'data-controller': 'scanner' do %>
    <%= content_tag :canvas, nil, width: 400, height: 240, 'data-scanner-target': 'canvas' %>
    <%= form.text_field :name, class: 'form-control', 'data-scanner-target': 'output' %>
  <% end %>

Hi Dave, I did everything like you did  (I believe :)) ) but my camera doesn't start. I don't see any errors in my console and my canvas is displayed. What I have different is the ruby '2.4.1' and 'rails', '~> 5.2.4', '>= 5.2.4.4'. Do you think those can block my camera?
Thanks

 

  ovi_tsb Look at your browser's console to see if there are any errors

I rebuild everything in rails 6  like you have and it's working.
Please help me with searching. I want something like when you scan a QRcode what exist in a product send to show page and if is not saved send to new product page.
After scanning the code it give me the path of the product not the name like in your case

A QR code is really just an encoded text. There isn't really any kind of data structure to it. So it can have text like the product name or a URL to it.
