How to remove id from select active record?

Question

Query on console

User.select('email','dob')

returns,

[#<User:0x000000084a9b08 id: nil, email: "[email protected]">,

Why am I getting id attributes in rails 4? How to get rid of this?

Answer 1

Pluck only returns the values if you want keys and values then try this:

User.select('email','dob').as_json(:except => :id) In my case the desired result was a JSON object. So, inside the as_json method you can exclude any column you desire

(additionally you can invoke object methods or access associated tables as well)

Answer 2

This will give you desired output

User.pluck(:email, :dob)
