How can we pass a variable and use it inside a yml file

Question

I need to perform string interpolation inside yml file, to create a custom error message based on a value which I will pass to locale yml file.

something like

users:
  error1: "custom error message based on variable #{passed_in_var}"

Is this possible?

Answer 1

Use I18n interpolation!

users:
  error1: "custom error message based on variable %{passed_in_var}"

Then you call it like this:

t('users.error1', passed_in_var: 'foobar')
