Question

given a string of emails like:

emails = "[e-mail], [e-mail], [e-mail], [e-mail]"

With one query, I would like to return all matching User records where:

User.rb (id,email)

Here is my query, but it does not return results if I have emails set to more than one email:

User.where("email IN (?)", emails)
  User Load (1.0ms)  SELECT "users".* FROM "users" WHERE (users.deleted_at IS NULL) AND (email IN ('[e-mail],, [e-mail], [e-mail], [e-mail]'))
 => [] 

Suggestions on how to update this User.where query to get all matching Users from the emails provided? Thank you.

Answer 1

First, turn the emails into an Array:

emails = "[e-mail], [e-mail], [e-mail], [e-mail]".split(', ')

Then you can call:

User.where(:email => emails)
