I have an index page that builds a table, and I am trying to allow users to edit line\'s in the table. I am trying to do this in the most basic way possible - no javascript
I have to share my experience :
I played with Turbolinks, like you. But suddently, I had an issue : the previous pages needed to have turbolinks disabled too, to work.
After many & many & many hours on the issue, I found the solution :
Correct:<% f.submit %> was separated by 2
<%= f.file_field :brand_picture %>
<%= f.file_field :brand_picture %>
