Ruby-on-Rails Rake导入意外的tASSOC

Question

I'm trying to load data from a csv as a rake task with the following code:

require 'csv'

desc "Import Users from csv file"
task :import_users => [:environment] do

file = "db/users.csv"

CSV.foreach(file, :headers => true) do |row|
User.create {
  :name => row[1],
  :email => row[2],
  :password => row[3],
  :password_confirmation => row[4],
  :admin => row[5]
}
end

end

and the CSV:

name,email,password,password_confirmation,admin
john smith,js@mail.com,password,password,TRUE

im getting the a unexpected tASSOC error for each attribute.

Answer 1

If you put brackets around your hash in the create method it will work fine:

User.create({
  :name => row[1],
  :email => row[2],
  :password => row[3],
  :password_confirmation => row[4],
  :admin => row[5]
})

Basically ruby doesn't understand that this is a method call with a hash as the parameter. By putting the brackets there you make it explicit that that is what you mean.
