Code challenge for CareDash
I wanted to make sure this app worked on more than just my machine so I double checked on a different computer and was getting an issue booting to the server saying there was a pending migration. I migrated and re-pushed code and issue persisted.
Migrating on the other machine creates a database issue.
Deploying to heroku yields same result:

rails aborted!
StandardError: An error has occurred, this and all later migrations canceled:
PG::UndefinedTable: ERROR: table "users" does not exist
: DROP TABLE "users"
And then a whole bunch of other errors.
I have a migration with a users table:
class CreateUsers < ActiveRecord::Migration[5.0]
def change
create_table :users do |t|
t.string :first_name
t.string :last_name
t.string :email
t.timestamps
end
end
end
My Gemfile is set up for production:
source 'https://rubygems.org'
git_source(:github) do |repo_name|
repo_name = "#{repo_name}/#{repo_name}" unless repo_name.include?("/")
"https://github.com/#{repo_name}.git"
end
