I've deployed my app to Heroku however whenever I try to search for a
professor or even view an individual professor (without searching) I
just get "We're sorry, but something went wrong."
Running heroku logs returns:

I've seen a similar issue discussed on Stack Overflow and someone said
that elastic search may not be running. But if I run curl
localhost:9200 there is a hash so I believe it's running and I don't
think that's the problem.
Any help would be greatly appreciated I'm very lost this is my first app
I'm building mostly to teach myself rails so I've never deployed
anything before.
If you cannot even view an record then there it is something more than
a search problem. What does the log show when you just try to view?
Always fix the simplest problem first.
Wait, what?? "localhost" from your development system is not the
same as "localhost" from a Heroku-deployed application.
You need to sign up for a Heroku ElasticSearch add-on or run your
own ES instance somewhere; in either case, the access URL will
certainly not be for "localhost"
It seems to be having a problem with showing the name, I don't know why
this is a problem this page works fine on localhost. One possible thing
I can think of is that I created a column "firstname" in a recent
migration (still well before I pushed this to Heroku) could it be
possible that Postgres is using an earlier migration then SQLite?
This is my show.hm.erb where the offending method is:
Have a look at the database itself and see. I don't know how to do
that on Heroku but I am sure google will tell you if not some
documentation on Heroku.
However I note that the error is referring to fullname but you say you
added a column firstname so perhaps that is the issue.
So the problem displaying the record was indeed because Heroku was on an
older migration of the DB. So after migrating to the changed column
names I can access records.
Elasticsearch still eludes me I've been going through this resource:
Ruby on Rails - bonsai trying to get bonsai to work I
get to the last step "Index your documents" but I'm not sure what to put
for "curl -XPUT
http://username:password@redwood-12345.us-east-1.bonsai.io/users" is it
just my Heroku username, password and app? Sorry I just can't find a lot
of resources to help me deploy Searchkick via Elasticsearch anywhere.
I've tried to clean it up nicely (when it was private it was a little
untidy and still is). I have those gems installed but whenever I try to
load the app in Heroku it crashes:

and now whenever I view the app in localhost it also crashes:

That looks like you have a typo somewhere in your app - Eastic instead of Elastic.
Thank you so much! I've made those changes and pushed them to Github,
it's working on my localhost, after work if I have time I'll try to push
it to Heroku and see if it works.
Then I had to reindex the DB and migrate to Heroku. Just to see if it
would work I copied that code directly from an answer on Stack Overflow
but now I'm wondering about the AWS url in the if statement, because
that works for me but I have no idea where that URL is from since I
don't personally have an AWS account, is there another more free place
to host your Elasticsearch? By using this URL am I hijacking someone
else's AWS's account?

That does look like the the AWS provided elasticsearch hosting service. If that URL is part of the copied post, then yes you are using someone else's elasticsearch instance (if you're feeling helpful you could alert whoever posted their data)
