Hi , I am new to rails… I am having a line in the mailing queue.rb file  
as

subject =“Mail : Welcome to app”

I have added translation for Welcome to app as

str\_welcome: “Welcome to app”

Now i am trying to replace Welcome to app in the file with the  
str\_welcome

how to do that as i have another prefix (“Mail”) also …

Or you could try nesting a translation:

subject = I18n.t(:mail, :title =\> I18n.t(“str\_welcome”))

Your mail translation would look like:

mail: “Mail: %{title}”

Try subject=“Mail: #{I18n.t(“str\_welcome”)}”
