Rails 4.0.1 on Heroku, can't create database

Question

I can't get rake db:migrate to run on my rails 4.0.1 app on Heroku.

I'm guessing that I don't have postgres configured properly... but reading the docs on heroku hasn't really helped and I'm not sure what to do. I don't know too much about heroku or postgres.

Any help or resources would be greatly appreciated. Let me know if there's anything else I can post.

(Also, I'm using devise, if that matters)

When I run heroku run rake db:migrate I get this:

Running `rake db:migrate` attached to terminal... up, run.5077
PG::UndefinedTable: ERROR:  relation "users" does not exist
LINE 5:                WHERE a.attrelid = '"users"'::regclass
                                      ^
:               SELECT a.attname, format_type(a.atttypid, a.atttypmod),
                 pg_get_expr(d.adbin, d.adrelid), a.attnotnull, a.atttypid, a.atttypmod
            FROM pg_attribute a LEFT JOIN pg_attrdef d
              ON a.attrelid = d.adrelid AND a.attnum = d.adnum
           WHERE a.attrelid = '"users"'::regclass
             AND a.attnum > 0 AND NOT a.attisdropped
           ORDER BY a.attnum

rake aborted!

              ON a.attrelid = d.adrelid AND a.attnum = d.adnum

             AND a.attnum > 0 AND NOT a.attisdropped
           ORDER BY a.attnum

When I run heroku run rake db:setup I get this:

FATAL:  permission denied for database "postgres"
DETAIL:  User does not have CONNECT privilege.

Answer 1

I would first try

heroku restart

heroku rake db:migrate

If that doesn't work, then try.

heroku pg:reset DATABASE_URL   #Literally type in heroku pg:reset DATABASE_URL

heroku rake db:migrate

Answer 2

I should've read the stack trace more closely. My factories.rb was creating user objects as attributes for other factories. Wrapping them in a block fixed it:

FactoryGirl screws up rake db:migrate process
