interpolate(locale, string, values = {}) — I18n::Backend::Simple

interpolate(locale, string, values = {})

Interpolates values into a given string.

interpolate "file {{file}} opened by \\{{user}}", :file => 'test.txt', :user => 'Mr. X'  
# => "file test.txt opened by {{user}}"

Note that you have to double escape the \ when you want to escape the {{...}} key in a string (once for the string and once for the interpolation).

Parameters

locale req
