Answer 1

Looking at the error, it seems like there is no name attribute in users table. While creating a user record you are passing the non-existing attribute and getting the error.

To resolve this issue,

Either add a column to users table called name By:

Generating a migration
  rails generate migration AddNameToUsers name:string
Running 
  rake db:migrate

Or

Remove the name attribute and value from list of arguments passed to User.create method.
