just checking in for reference, trying to use artist name instead of artist id as part of the url, not quite working yet, I just want to check in so I have a record of how it *doesnt* work
changed to search for artists by permalink, might be able to get away with just using name turned into a string though
OH YEAH, find_or_create_by! Can now add artists to our db simply by searching for them.
some cosmetic changes to artists page
 add migration to add permalink column
removing the artists part of the path from the view, as it is looking in the wrong place on heroku...
add to_i to put a type on artist added_by, as it seems postgres needs that made explicit
reverse those last two changes, try making the added_by a string instead of an integer
