Question

I’m using postgresql
Devise stores emails in db with downcase:
config.case_insensitive_keys = [ :email ]

But when i login with uppercased email – i got error that email is wrong.
I find solition for this, but this have 1 trouble:

def self.find_for_authentication(conditions = {})
    # Allow to log in with case insensitive email
    conditions[:email].downcase!
end

1) When I try to logged in with wrong uppercased email I got error and my email with downcase. (logged with [e-mail], got [e-mail], but i need to show [e-mail]). How can I change this behaviour ?

Answer 1

Solution was really simple. What you need is just copy params hash and change email in this hash when login, but when user got exception – we just return original hash with entered params

def self.find_for_authentication(conditions = {})
  # Allow to log in with case insensitive email
  new_hash = conditions.dup
  new_hash[:email] = conditions[:email].downcase
  where(new_hash).first
end
