Question

I basically want to have the environment check done in javascript only, so I don’t have to litter my view files with Rails.env.production? checks.

Answer 1

The easiest way to do this I believe is to set a javascript variable to the value of Rails.env and then add a method in application.js to check it. The best place is probably in your layout so in app/views/layouts/my_layout.html.erb something like:

<script type="text/javascript">
  var rails_env = '<%= Rails.env %>';
</script>

Which you can then use in your javascript code.
