Question

I am using devise_invitable.

I am trying to find all users with invitation_token != nil

I thought that User.where(:invitation_token != nil)
will do.. but it returns all users..

when I do

pry(main)> User.where(:invitation_token != nil)[0].invitation_token
  User Load (1.0ms)  SELECT "users".* FROM "users" WHERE ('t')
=> nil

so I don’t understand what’s going on here.. How do I find models using where when the test is false?

Answer 1

You should do:

User.where('invitation_token IS NOT NULL')

Your solution does not work, because :invitation_token != nil will evaluate to true, so what you actually did was:

User.where(true)
