Ruby on Rails

May all the gods of all the religions bless you, your house, your family, your extended family, and your friends with health, happiness, long life, and great wealth.

Jesus, I spent an entire week on this!!!

Do you know of a document or link that explains how Turbolinks works?

This is my first post here.  Comments on style, etc., are appreciated.

An answer is even more appreciated.

This is a continuation of my question at https://stackoverflow.com/questions/44856528/how-to-trace-a-html-button-non-event-rails-authorization-with-pundit

The problem:

Figure 1:
I have a form:

The first time I visit this page, everything seems to work. I can click on "Change Role" and update the appropriate row in the Postgres table.  I can do it as many times as I like with no problems.


If I click on, for instance, somename@yahoo.com (highlighted in yellow), I get to the following page:
Figure 2:

The above is just fine.

If I click on Users on the upper right, I return to the webage denoted as Figure 1.



Now things get, hmm, (un)interesting.

When I click on Change Role, nothing happens. 

I have hooked up Wireshark and I am almost 100% sure I see no Post going out when I click on Change Role.  I am pretty sure I see no outbound http when I click on Change Role

If I refresh the page, Change Role starts working again!

I am clueless where to look or what is going on.
