Question

Is there any proper way to detect the environment (development or production) in the application layout? Say, I don’t want to render the GA code in my local sandbox.

In Django we use {% if not debug %}{% include '_ga.html' %}{% endif %}. What should I use in Rails? Thanks.

You can use:

Rails.env.production?
#or
Rails.env.development?
#or
Rails.env.test?

See docs for further information. So, you could do something like:

<% if Rails.env.development? %>
  <p>Dev Mode</p>
<% else %>
  <p>Production or test mode</p>
<% end %>
