Devise and Strong Parameters

Question

I would like to know how to integrate both of this gems(devise + Strong Parameters), since strong params will likely be added to the rails core in 4.0

any help is welcome thanks

Answer 1

Update for devise 4.x

class ApplicationController < ActionController::Base   before_filter :configure_permitted_parameters, if: :devise_controller?    protected    def configure_permitted_parameters     devise_parameter_sanitizer.permit(:sign_up, keys: [:username])     devise_parameter_sanitizer.permit(:sign_in, keys: [:username])     devise_parameter_sanitizer.permit(:account_update, keys: [:username])   end end 

---

After adding both gems, devise will work as normal.

Update: With the latest version of Devise 3.x, as described at devise#strong-parameters, the authentication key (normally the email field), and the password fields are already permitted. However, if there are any additional fields on the signup form, you will need to let Devise know the extra fields to permit. The easiest way to do this is with a filter:

class ApplicationController < ActionController::Base   before_filter :configure_permitted_parameters, if: :devise_controller?    protected    def configure_permitted_parameters     devise_parameter_sanitizer.for(:sign_up) << :username   end end 

For Devise 2.x, if you use the safety feature requiring explicitly whitelisting tainted parameters in the user model:

include ActiveModel::ForbiddenAttributesProtection 

the changes needed are found at https://gist.github.com/3350730 which overrides some of the controllers.

Answer 2

The easy way is to add a simple before filter in your ApplicationController. If you have different roles and/or other more complex scenario there are other options on the link below:

Answer 3

before_filter :configure_sanitized_params, if: :devise_controller?

def configure_sanitized_params
  devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:firstname, :designation_id, :middlename, :previous_experiance_year, :previous_experiance_month, :lastname, :email, :username, :password, :password_confirmation, :previous_experiance, :empid, :dob, :timezone, :doj, :gender, :education, :comments, :locked, :deactivated, :reason, :phone, :deactivated_date, :image) }
  devise_parameter_sanitizer.for(:account_update) { |u| u.permit(:remove_image, :firstname, :designation_id, :middlename, :lastname, :email, :username, :empid, :dob, :timezone, :doj, :gender, :education, :comments, :locked, :deactivated, :reason, :phone, :deactivated_date, :image) }
end
