Rails 4 Strong Parameters opposite permit all attributes - ruby-on-rails

I am using rails 4 with strong parameters and trying to figure out how to set the strong parameters to not allow any attribute with the parameter.
I read this Rails 4 Strong parameters : permit all attributes? And would like to do the opposite of that.
params.require(:user).permit!
would permit all attributes, how could I do the opposite?
UPDATE THIS IS MY FULL CODE:
in app/controllers/application_controller.rb
class ApplicationController < ActionController::Base
# Prevent CSRF attacks by raising an exception.
# For APIs, you may want to use :null_session instead.
protect_from_forgery with: :exception
before_filter :configure_permitted_parameters, if: :devise_controller?
protected
def configure_permitted_parameters
devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:username, :email, :password, :password_confirmation, :remember_me) }
devise_parameter_sanitizer.for(:sign_in) { |u| u.permit(:signin, :password, :remember_me) }
devise_parameter_sanitizer.for(:account_update) {|u| u.permit(:username, :email, :password, :password_confirmation, :current_password)}
devise_parameter_sanitizer.for(:sign_in) { |a| a.permit(:signin, :password, :remember_me) }
devise_parameter_sanitizer.for(:account_update) {|a| a.permit(:username, :email, :password, :password_confirmation, :current_password)}
end
end
in app/models/admin.rb
class Admin < ActiveRecord::Base
# Include default devise modules. Others available are:
# :confirmable, :lockable, :timeoutable and :omniauthable, :registerable
devise :database_authenticatable, :registerable, :recoverable, :rememberable, :trackable, :validatable
attr_accessor :signin
def self.find_first_by_auth_conditions(warden_conditions)
conditions = warden_conditions.dup
if login = conditions.delete(:signin)
where(conditions).where(["username = :value OR lower(email) = lower(:value)", { :value => login }]).first
else
where(conditions).first
end
end
validates :username, presence: true, length: {maximum: 255}, uniqueness: { case_sensitive: false }, format: { with: /\A[a-zA-Z0-9]*\z/, message: "may only contain letters and numbers." }
end
The users.rb model is the same as the admin.rb model. This leads to two different sign up/sign in links- 1 for each model. Also I need to leave the :registerable module so that I can override the default devise's registerable module. However I modified the views to not show the admin page when typed in a browser. --- I only need to block it via command line now.
I also have posted a previous question similar to this:
Rails 4 Devise Strong Parameters Admin Model

If you're not using any user-inputted parameters (like for a GET), you don't need to use params at all. Your controller will just work, and there won't be a security issue.

The default behavior is the opposite of .permit. If you don't mention an attribute in your params arguments, it is like denying the user access to do anything with those attributes.

Rails 5 - Devise - When I login it always logs me in as the same user regardless of what credentials are used

Everything was set up fine and seemed to be working. Suddenly I have an issue where if I log out and then log back in again with a different username it just logs me back in always as the first user.
Example:
user one - first#domain.com / password1
user two - second#domain.com / password2
Even if I log out and then log back in again as user two (verified as signed up correctly) it will log me in as user one.
Here is my user.rb file
class User < ApplicationRecord
# Include default devise modules. Others available are:
# :confirmable, :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
acts_as_voter
has_many :links
has_many :comments
# Virtual attribute for authenticating by either username or email
# This is in addition to a real persisted field like 'username'
attr_accessor :login
def self.find_for_database_authentication(warden_conditions)
conditions = warden_conditions.dup
if login = conditions.delete(:login)
where(conditions.to_h).where(["lower(username) = :value OR lower(email) = :value", { :value => login.downcase }]).first
elsif conditions.has_key?(:username) || conditions.has_key?(:email)
where(conditions.to_h).first
end
conditions[:email].downcase! if conditions[:email]
where(conditions.to_h).first
end
validates :username, presence: :true, uniqueness: { case_sensitive: false }
validates_format_of :username, with: /^[a-zA-Z0-9_\.]*$/, :multiline => true
validate :validate_username
def validate_username
if User.where(email: username).exists?
errors.add(:username, :invalid)
end
end
end
Application Controller
class ApplicationController < ActionController::Base
protect_from_forgery with: :exception
before_action :configure_permitted_parameters, if: :devise_controller?
protected
def configure_permitted_parameters
added_attrs = [:username, :email, :password, :password_confirmation, :remember_me]
devise_parameter_sanitizer.permit :sign_up, keys: added_attrs
devise_parameter_sanitizer.permit :account_update, keys: added_attrs
end
end
You might want to check your controllers. If you're determining the logged in user by using anything other than current_user, you may have used the wrong query or perhaps were using a specific user for testing purposes.
Check your User model. You're using :rememberable and might be passing a session cookie without realizing.

How to permit a new parameter in rails (devise) when implementing role based authorization

I'm working on creating an application with role based authorization.So,In i have created a migration to devise users to add a new column "role"
And I have the following code block in my applications controller to permit the new parameter(role).But still when i try to sign up as a new user.I get the error that the parameter role is unpermitted.Please help me to solve this issue.
class ApplicationController < ActionController::Base
protect_from_forgery with: :exception
before_action :configure_permitted_parameters, if: :devise_controller?
protected
def configure_permitted_parameters
devise_parameter_sanitizer.permit(:sign_up) { |u| u.permit( :email, :password, :password_confirmation, roles: [] ) }
end
end
This is what i've got in my user model
class User < ApplicationRecord
belongs_to :role
# has_many :Product
# Include default devise modules. Others available are:
# :confirmable, :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
ROLES = %i[admin manager customer]
def user_params
params.require(:user).permit(:name, :email, :password, :password_confirmation, :role)
end
end
migration is as follows
class AddRoleToUsers < ActiveRecord::Migration[5.0]
def change
add_column :users, :role, :string
end
end
Please help me to solve this issue.Thank you.
Your user model doesn't have access to params, so you can remove the user_params method from there. Unless you're nesting attributes, you won't need to pass in the array for the role attribute, so change
devise_parameter_sanitizer.permit(:sign_up) { |u| u.permit( :email, :password, :password_confirmation, roles: [] ) }
to
devise_parameter_sanitizer.permit(:sign_up) { |u| u.permit( :email, :password, :password_confirmation, :role ) }
#
And you should be good to go.

Devise with nested_attributes—field showing data but not updating the model

I have the following code (in Slim format), which displays a form for users. The user's data displays and updates on submit. However, phone which is a nested attribute from publisher displays current data when I load the form, but wont update on submit.
View
= form_for current_user, url: user_registration_path, html: {class: 'account'} do |user_form|
.row
.control-group.text-center
label.col-9 Email
= user_form.text_field :email, class: 'col-7'
= fields_for :publisher, current_user.publisher do |publisher_form|
.row
.control-group.text-center
label.col-9 Phone
= publisher_form.text_field :phone, class: 'col-7'
Registrations Controller
class RegistrationsController < Devise::RegistrationsController
def update_resource(resource, params)
resource.update_without_password(params)
end
end
Application Controller
class ApplicationController < ActionController::Base
# Prevent CSRF attacks by raising an exception.
# For APIs, you may want to use :null_session instead.
protect_from_forgery with: :exception
before_action :configure_permitted_parameters, if: :devise_controller?
protected
def configure_permitted_parameters
devise_parameter_sanitizer.for(:account_update) {|u| u.permit(
:first_name,
:last_name,
:email,
:password,
:password_confirmation,
:current_password,
publisher_attributes: [:phone, :payment_details],
banner_attributes: [:website, :banner_msg, :signup_msg, :bg_col, :txt_col, :btn_col]
)}
end
end
User Model
class User < ActiveRecord::Base
has_one :publisher
# Include default devise modules. Others available are:
# :confirmable, :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
accepts_nested_attributes_for :publisher
validates_presence_of :first_name, :last_name
validates_length_of :first_name, maximum: 100
validates_length_of :last_name, maximum: 100
end
I finally discovered that
= fields_for :publisher, current_user.publisher do |publisher_form|
should be:
= user_form.fields_for :publisher, current_user.publisher do |publisher_form|

Devise: I added a username field, but it's not working

I've added my a username field to my User model, but it seems that devise isn't recognizing it when creating a new user record. I fill out the email, username and password, but I get a validation error "Username can't be blank" even though my params hash clearly has it. I don't need to have people log in with their username, but I just need them to set it when registering for a new account.
I'm using rails 4 and I've implemented the strong parameters thing mentioned on devise's github README.
Here is my user.rb file
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
before_save { |user| user.username = user.username.downcase }
validates_presence_of :username
validates_uniqueness_of :username, case_sensitive: false
Here's my application_controller.rb file
class ApplicationController < ActionController::Base
protect_from_forgery with: :exception
before_filter :configure_permitted_parameters, if: :devise_controller?
protected
def configure_permitted_parameters
devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:email, :username, :password, :password) }
end
end
I've also added my registrations/new.html.erb file:
<div><%= f.label :username %>
<%= f.text_field :username %></div>
Here's what my params hash has when I submit a new user record:
user: !ruby/hash:ActionController::Parameters
username: David
email: david#example.com
password: foobar12
password_confirmation: foobar12
Any ideas?
As it turns out, my strong params above was incorrect.
I fixed it by changing it to this:
devise_parameter_sanitizer.for(:sign_up) do |u|
u.permit(:email, :username, :password, :password_confirmation)
end

Rails 4 + Devise 3.0.0 Adding Username

I'm working with Rails 4 and Devise 3.0.0 and am new to using these new strong paramters. I added a username to the User model using the documentation on the Devise wiki. The problem I'm running into is the strong parameters change in Rails 4.
How do I add the :login attribute to the user model to enable logging in with either the username or email?
From the rails4 readme on devise: https://github.com/plataformatec/devise/tree/rails4#strong-parameters
class ApplicationController < ActionController::Base
before_filter :configure_permitted_parameters, if: :devise_controller?
protected
def configure_permitted_parameters
devise_parameter_sanitizer.for(:sign_in) { |u| u.permit(:login, :email) }
end
end
#justin.chmura
Here is a gist of how we ended up getting it working.
https://gist.github.com/AJ-Acevedo/6077336
Gist contains:
app/controllers/application_controller.rb
app/models/user.rb
config/initializers/devise.rb
You should make sure that you include the
attr_accessor :login
in the user model. Here is where I found the question explaining that attr_accessible is deprecated.
Rails 4 + Devise Login with email or username and strong parameters
Difference between attr_accessor and attr_accessible
This is what my app/models/user.rb file looks like.
class User < ActiveRecord::Base
# Include default devise modules. Others available are:
# :confirmable, :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
attr_accessor :login
def self.find_first_by_auth_conditions(warden_conditions)
conditions = warden_conditions.dup
if login = conditions.delete(:login)
where(conditions).where(["username = :value OR lower(email) = lower(:value)", { :value => login }]).first
else
where(conditions).first
end
end
validates :username,
:uniqueness => {
:case_sensitive => false
}
end
It will works fine if you add an module in config/initializers as followings with all parameters,
File config/initializers/devise_permitted_parameters.rb with following contents:
module DevisePermittedParameters
extend ActiveSupport::Concern
included do
before_filter :configure_permitted_parameters
end
protected
def configure_permitted_parameters
devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:username, :email, :password, :password_confirmation) }
end
end
DeviseController.send :include, DevisePermittedParameters
