Creating Customer Data on Rails Console

Hi, I have managed to follow along this video until the very end where Hampton creates customer data for Bob's Emporium. In the Rails Console, he entered: Customer.create(name: "Bob's Emporium", email: "bob@emporium.com"). When I tried to enter this I got the following error:

    from bin/rails:4:in `<main>'irb(main):011:0> Customer.create(name: "Bob's Emporium", email: "bob@empor

ium.com") ActiveRecord::UnknownAttributeError: unknown attribute 'name' for Customer. from C:/Ruby200-x64/lib/ruby/gems/2.0.0/gems/activerecord-4.2.3/lib/active_record/attribute_assignment .rb:59:in rescue in _assign_attribute' from C:/Ruby200-x64/lib/ruby/gems/2.0.0/gems/activerecord-4.2.3/lib/active_record/attribute_assignment .rb:54:in_assign_attribute' from C:/Ruby200-x64/lib/ruby/gems/2.0.0/gems/activerecord-4.2.3/lib/active_record/attribute_assignment .rb:41:in block in assign_attributes' from C:/Ruby200-x64/lib/ruby/gems/2.0.0/gems/activerecord-4.2.3/lib/active_record/attribute_assignment .rb:35:ineach' from C:/Ruby200-x64/lib/ruby/gems/2.0.0/gems/activerecord-4.2.3/lib/active_record/attribute_assignment .rb:35:in assign_attributes' from C:/Ruby200-x64/lib/ruby/gems/2.0.0/gems/activerecord-4.2.3/lib/active_record/core.rb:564:ininit _attributes' from C:/Ruby200-x64/lib/ruby/gems/2.0.0/gems/activerecord-4.2.3/lib/active_record/core.rb:281:in init ialize' from C:/Ruby200-x64/lib/ruby/gems/2.0.0/gems/activerecord-4.2.3/lib/active_record/inheritance.rb:61:in new' from C:/Ruby200-x64/lib/ruby/gems/2.0.0/gems/activerecord-4.2.3/lib/active_record/inheritance.rb:61:in new' from C:/Ruby200-x64/lib/ruby/gems/2.0.0/gems/activerecord-4.2.3/lib/active_record/persistence.rb:33:in create' from (irb):11 from C:/Ruby200-x64/lib/ruby/gems/2.0.0/gems/railties-4.2.3/lib/rails/commands/console.rb:110:in star t' from C:/Ruby200-x64/lib/ruby/gems/2.0.0/gems/railties-4.2.3/lib/rails/commands/console.rb:9:instart'

It seems when you made your own Customer model or when you were creating the migration for the Customer model, you may have left out the name attribute. If we look at the error, we see: 

ActiveRecord::UnknownAttributeError: unknown attribute 'name' for Customer

Check your model and/or migration for Customer and try again. Hope this helps!
