Defining mandatory fields when creating a new issue

Added by steven gebbie over 8 years ago

I require the Description field to be mandatory and have the red * beside it,
I've been searching and edited app/models/issue.rb and added changed
validates_presence_of :subject, :priority, :project, :tracker, :author, :status
to also include , :description

so now this field is mandatory but it doesnt show the red *.
can anyone tell me what I am missing
