How do you create an array from the fields from a database resultset in Ruby on Rails?

Question

Basically I have 3 fields in the database table and I want to return a an array to represent each row.

sqlite database resultset:

row 1)
name: John
gender: male
email: john@john.com

row 2)
name: Sarah
gender: female
email: sarah@sarah.com

Desired format from the above resultset:

[['John',male,'john@john.com'],['Sarah',female,'sarah@sarah.com']]

I've tried using User.all.map(&:name) but that only gives me ['John','Sarah']

Answer 1

您将要使用map ，但是像这样：

User.all.map {|u| [u.name, u.gender, u.email]}

Answer 2

User.all.map {|u| [u.name, u.gender, u.email] }
