how to get user name in a view instead of uid I have a drupal 7 website that uses a view to show the content.  The Content UID shows as a field I can display, but I want to display the username instead.  It says "The user authoring the content. If you need more fields than the uid add the content: author relationship"  , which I don't understand .  Where do I add the content author relationship?
thank you,
it's in the advanced configuration (click on add relationship):



search and select the uid field (this applies also for entity references for instance)



add a new field to the output, select User: name



select the relationship you created earlier (you can have multiple relationships, e.g. if you have multiple entity references)
