In a Rails view helper, the t function is an invocation of the underlying internationalization or I18n functions. You do something like this:

<%= t('api.v1.success.update', klass: Tip)%>

and you get back a string like this:

"%{klass} updated successfully"

where klass was interpolated to be the name of the passed in klass variable.

If you want to do this in Rails console then you need to call I18n as the parent object i.e.:

I18n.t('api.v1.success.update', klass: Tip)
