问题
Searching around, I see that variations on this question used to be asked on StackOverflow fairly often, but nothing in recent years. That makes me wonder if perhaps I have something that is out of date, perhaps a Javascript library. We just started working on a new Rails 4 site, using Ruby 2, however we accepted the frontend code from our designer, and we used it mostly untouched. That includes:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
We have a log out link:
<%= link_to('LOG OUT', main_app.destroy_user_session_path, :method => :delete) %>
Sadly, when we click on this, the browser does a GET instead of a DELETE:

This could also be a conflict with RefineryCSM, which we are using for some of our site.
These are all the routes in our system:
