:following, :followers]

end
Confirms the correct user.
def correct_user

redirect_to(root_url) unless current_user?(@user)
end
Confirms an admin user.
def admin_user
redirect_to(root_url) unless current_user.admin?
end
end
users model is shown below
class User < ApplicationRecord
attr_accessor :remember_token, :activation_token, :reset_token
before_save :downcase_email
before_create :create_activation_digest
validates :name, presence: true, length: { maximum: 50 }
VALID_EMAIL_REGEX = /\A[\w+-.]+@[a-z\d-.]+.[a-z]+\z/i
validates :email, presence: true, length: { maximum: 255 },
format: { with: VALID_EMAIL_REGEX },
uniqueness: { case_sensitive: false }
has_secure_password
validates :password, presence: true, length: { minimum: 6 }, allow_nil: true
Returns the hash digest of the given string.
def User.digest(string)
cost = ActiveModel::SecurePassword.min_cost ? BCrypt::Engine::MIN_COST :
BCrypt::Engine.cost
BCrypt::Password.create(string, cost: cost)
end
Returns a random token.
def User.new_token
SecureRandom.urlsafe_base64
end
Remembers a user in the database for use in persistent sessions.
def remember
self.remember_token = User.new_token
update_attribute(:remember_digest, User.digest(remember_token))
end
Returns true if the given token matches the digest.
def authenticated?(attribute, token)
digest = send(“#{attribute}_digest”)
return false if digest.nil?
BCrypt::Password.new(digest).is_password?(token)
end
Forgets a user.
def forget
update_attribute(:remember_digest, nil)
end
Activates an account.
def activate
update_columns(activated: true, activated_at: Time.zone.now)
end
Sends activation email.
def send_activation_email
UserMailer.account_activation(self).deliver_now
end
Sets the password reset attributes.
def create_reset_digest
self.reset_token = User.new_token
update_attribute(:reset_digest, User.digest(reset_token))
update_attribute(:reset_sent_at, Time.zone.now)
end
Sends password reset email.
def send_password_reset_email
UserMailer.password_reset(self).deliver_now
end
Returns true if a password reset has expired.
def password_reset_expired?
reset_sent_at < 2.hours.ago
end
Returns a user’s status feed.
private
Converts email to all lower-case.
def downcase_email
email.downcase!
#self.email = email.downcase
end
Creates and assigns the activation token and digest.
def create_activation_digest
self.activation_token = User.new_token
self.activation_digest = User.digest(activation_token)
end
end
index.html.erb is shown below
<% provide(:title, ‘All users’) %>
All users
<%= will_paginate %>
<%= render @users %>
<%= will_paginate %>
Is it possible to alter the index file so that only admin users see it and the link in the header file?
Cheers Dave
