不允许的参数将新字段添加到Rails中的Devise中

Question

when a user make a sign up and press sign up i get this error

undefined method `for' for #<Devise::ParameterSanitizer:0x007fe4c2821988> Did you mean? fork

  }
elsif params[:action] == 'create'
  devise_parameter_sanitizer.for(:sign_up) { 
    |u| u.permit(registration_params) 
  }
end

this is my application controller

class ApplicationController < ActionController::Base
  protect_from_forgery with: :exception
  before_action :configure_devise_permitted_parameters, if: :devise_controller?

  protected
  def configure_devise_permitted_parameters
    registration_params = [
       :first_name, :last_name, :address, :gender, :DOB, 
       :email, :password, :password_confirmation, 
       :image, :thumb, :medium
    ]

    if params[:action] == 'update'
      devise_parameter_sanitizer.for(:account_update) { 
        |u| u.permit(registration_params << :current_password)
      }
    elsif params[:action] == 'create'
      devise_parameter_sanitizer.for(:sign_up) { 
        |u| u.permit(registration_params) 
      }
    end
  end
end

can i know what is the problem and how to solve it

Answer 1

In order to fix this problem, replace for with permit in your code.

Explanation:

The method #for on Devise::ParamsSanitizer has been removed in devise 4.2, and replaced with two new methods #sanitize and #permit .

#permit takes a block argument, so it is probably what you want to use here.

see:

Answer 2

You may use this code for reference and change the params of your column name in user table that you want.i am using username Add this in your application_controller.rb

  before_filter :configure_permitted_parameters, if: :devise_controller?

###### PROTECTED METHODS #######################
  protected
  def configure_permitted_parameters
    devise_parameter_sanitizer.for(:account_update) << :username
    devise_parameter_sanitizer.for(:sign_up) << :username
  end

Hope this helps :)

Answer 3

you have problem on signup time so permit params this way. also check Strong Parameters on device gem.

before_filter :update_sanitized_params, only: [:create], if: :devise_controller?

    protected
        def update_sanitized_params
          devise_parameter_sanitizer.for(:sign_up) {|u| u.permit(:first_name, :last_name, :address, :gender, :DOB,:email, :password, :password_confirmation,:image, :thumb, :medium)}
        end

Answer 4

well, actually i fixed it but the thing is when i go to console do User.last and i get nill

class ApplicationController < ActionController::Base
protect_from_forgery with: :exception
before_action :configure_devise_permitted_parameters, if: :devise_controller?

protected
def configure_devise_permitted_parameters
registration_params = [
   :first_name, :last_name, :address, :gender, :DOB, 
   :email, :password, :password_confirmation, 
   :image, :thumb, :medium
]

if params[:action] == 'update'
  devise_parameter_sanitizer.for(:account_update) { 
    |u| u.permit(registration_params << :current_password)
  }
elsif params[:action] == 'create'
  def configure_devise_permitted_parameters
  devise_parameter_sanitizer.fot(:sign_up).push(registration_params)
end
end
end

end
