Rails - Devise, Email Case Insensitivity

Question

I'm using Devise with login credentials: email/password - no usernames

I just noticed that the login process is case sensitive for emails. so if you register with [email protected], and then try to log in with [email protected] you get an error. Very confusing.

How can I make devise log people in with their email/password, and the email being case insensitive?

Answer 1

You can easily fix the issue like below.

# config/initializers/devise.rb
Devise.setup do |config|
  config.case_insensitive_keys = [:email, :username]
end
