UsersController#edit - request.formats: ["text/html"] request.variant: []

[thomami244]

Thanks for a great tutorial! I am a new/intermediate Ruby programmer, who has been trying to run your code with newer versions of Ruby/ Webpacker, due to installation problems with the given Ruby version.

I have run the code on Ruby v 3.0.0 and v 3.1.2, and I keep getting the same error message when I try to edit a cell in the table. It appears that the "edit.js.erb" file is no longer accepted, as it is expecting an html file instead.

I have done some research and it appears that perhaps adding the option xhr: true may solve this issue:
