Question

I want to print out some debug messages in my erb template when it is called in development mode, but not when it is called in production mode (i.e.)

<%= debug variable_name %>

However, this will be printed in any mode.

I found I can do

<% if logger.debug?
     debug variable_name
   end %>

which seems to work. Is this the proper way, or is there a more elegant solution?

You probably want to do something like this:

<%= debug(variable) if RAILS_ENV == 'development' %>

If you’re doing this often, you might want to create a quick helper method to clean up the code a little more:

def my_debug(debug_variable)
debug_variable if RAILS_ENV == 'development'
end

Then you can do this in your erb template/view

my_debug(variable_here)
