# Use this hook to configure devise mailer, warden hooks and so forth. The first
# four configuration values can also be set straight in your models.
Devise.setup do |config|
  # Configure the e-mail address which will be shown in DeviseMailer.
  config.mailer_sender = "support@locomotiveapp.org"

  # ==> Configuration for any authentication mechanism
  # Configure which keys are used when authenticating an user. By default is
  # just :email. You can configure it to use [:username, :subdomain], so for
  # authenticating an user, both parameters are required. Remember that those
  # parameters are used only when authenticating and not when retrieving from
  # session. If you need permissions, you should implement that in a before filter.
  # config.authentication_keys = [ :email ]

  # Tell if authentication through request.params is enabled. True by default.
  # config.params_authenticatable = true

  # Tell if authentication through HTTP Basic Auth is enabled. True by default.
  # config.http_authenticatable = true

  # The realm used in Http Basic Authentication
  # config.http_authentication_realm = "Application"

  # ==> Configuration for :database_authenticatable
  # Invoke `rake secret` and use the printed value to setup a pepper to generate
  # the encrypted password. By default no pepper is used.
  # config.pepper = "rake secret output"

  # Configure how many times you want the password is reencrypted. Default is 10.
  # config.stretches = 10

  # Define which will be the encryption algorithm. Supported algorithms are :sha1
  # (default), :sha512 and :bcrypt. Devise also supports encryptors from others
  # authentication tools as :clearance_sha1, :authlogic_sha512 (then you should set
  # stretches above to 20 for default behavior) and :restful_authentication_sha1
  # (then you should set stretches to 10, and copy REST_AUTH_SITE_KEY to pepper)
  config.encryptor = :sha1

  # ==> Configuration for :confirmable
  # The time you want give to your user to confirm his account. During this time
  # he will be able to access your application without confirming. Default is nil.
  # config.confirm_within = 2.days

  # ==> Configuration for :rememberable
  # The time the user will be remembered without asking for credentials again.
  # config.remember_for = 2.weeks

  # ==> Configuration for :validatable
  # Range for password length
  # config.password_length = 6..20

  # Regex to use to validate the email address
  # config.email_regexp = /^([\w\.%\+\-]+)@([\w\-]+\.)+([\w]{2,})$/i

  # ==> Configuration for :timeoutable
  # The time you want to timeout the user session without activity. After this
  # time the user will be asked for credentials again.
  # config.timeout_in = 10.minutes

  # ==> Configuration for :lockable
  # Defines which strategy will be used to lock an account.
  # :failed_attempts = Locks an account after a number of failed attempts to sign in.
  # :none            = No lock strategy. You should handle locking by yourself.
  # config.lock_strategy = :failed_attempts

  # Defines which strategy will be used to unlock an account.
  # :email = Sends an unlock link to the user email
  # :time  = Reanables login after a certain ammount of time (see :unlock_in below)
  # :both  = Enables both strategies
  # :none  = No unlock strategy. You should handle unlocking by yourself.
  # config.unlock_strategy = :both

  # Number of authentication tries before locking an account if lock_strategy
  # is failed attempts.
  # config.maximum_attempts = 20

  # Time interval to unlock the account if :time is enabled as unlock_strategy.
  # config.unlock_in = 1.hour

  # ==> Configuration for :token_authenticatable
  # Defines name of the authentication token params key
  # config.token_authentication_key = :auth_token

  # ==> General configuration
  # Load and configure the ORM. Supports :active_record (default), :mongoid
  # (requires mongo_ext installed) and :data_mapper (experimental).
  require 'active_support/core_ext/class/attribute'
  require 'devise/orm/mongoid'

  # Turn scoped views on. Before rendering "sessions/new", it will first check for
  # "sessions/users/new". It's turned off by default because it's slower if you
  # are using only default views.
  config.scoped_views = true

  # By default, devise detects the role accessed based on the url. So whenever
  # accessing "/users/sign_in", it knows you are accessing an User. This makes
  # routes as "/sign_in" not possible, unless you tell Devise to use the default
  # scope, setting true below.
  config.use_default_scope = true

  # Configure the default scope used by Devise. By default it's the first devise
  # role declared in your routes.
  config.default_scope = :account

  # If you want to use other strategies, that are not (yet) supported by Devise,
  # you can configure them inside the config.warden block. The example below
  # allows you to setup OAuth, using http://github.com/roman/warden_oauth
  #
  # config.warden do |manager|
  #   manager.oauth(:twitter) do |twitter|
  #     twitter.consumer_secret = <YOUR CONSUMER SECRET>
  #     twitter.consumer_key  = <YOUR CONSUMER KEY>
  #     twitter.options :site => 'http://twitter.com'
  #   end
  #   manager.default_strategies(:scope => :user).unshift :twitter_oauth
  # end
