20,594 Points'Customer' and 'Employee' not inheriting from 'Account'
I made sure I followed along with Hampton and yet when I run 'Customer.first' and/or 'Employee.first' I don't get any reference to the Account table. I've included lots of my code below; please let me know if you see any obvious errors.
Here's my code from Sublime:
class RemoveOldTables < ActiveRecord::Migration
def up
Customer.all.each do |c|
Account.create(name: c.name, about: c.about)
end
Employee.all.each do |e|
Account.create(name: e.name, email: e.email)
end
drop_table :customers
drop_table :employees
end
def down
end
end
class Employee < Account
has_many :time_entries
end
class Customer < Account
has_many :time_entries
end
class Account < ActiveRecord::Base
end
And the output from Terminal:
2.2.1 :003 > Employee.first
Employee Load (0.4ms) SELECT `employees`.* FROM `employees` ORDER BY `employees`.`id` ASC LIMIT 1
=> #<Employee id: 1, name: "Thomas", email: "tmurray@wholesale.com", created_at: "2015-11-30 05:48:17", updated_at: "2015-11-30 05:48:17">
2.2.1 :004 > Customer.first
Customer Load (0.2ms) SELECT `customers`.* FROM `customers` ORDER BY `customers`.`id` ASC LIMIT 1
=> #<Customer id: 1, name: "Bob's Wholesale", about: nil, balance: nil, created_at: "2015-11-30 02:11:06", updated_at: "2015-11-30 02:11:06", email: "bob@wholesale.com">

56,414 PointsDid you get any errors or odd messages when you did 'rake db:migrate'? Because those tables shouldn't exist anymore if it run correctly.

20,594 PointsThanks for the help Seth. Here's the output from my 'rake db:migrate' command. The only odd thing I notice is that there's no reference to the 'Customer' or 'Employee' models - just 'RemoveOldTables'.

28,888 PointsAnd you did create the Accounts table that Hampton does at 2:00 in right?
