How to use HTTP_USER_AGENT in Ruby on Rails?

Question

Ruby on Rails

I want to create a table of visits (entry date, exit date, what computer I came from, etc.), and I was told that I would have to use the user agent, but somehow I can’t figure out how to use the user agent and display the values. Will you help?

Answer 1

You need to use request.env[], and inside the parameters, something like this:

<%= request.env['HTTP_USER_AGENT'] %>
<%= request.env['REMOTE_ADDR'] %>
