Override devise registrations controller

Question

I have added a field to the sign-up form that is based on a different model  see How do I use nested attributes with the devise model for the gory details  This part is working fine   The problem now is when I save  it is failing in the create action of the registrations controller that is supplied by devise with an Activerecord  UnknownAttributeError on this field  company    I am assuming I need to override the registrations controller  or is there a better easier way I should be approaching this

A better and more organized way of overriding Devise controllers and views using namespaces:

Create the following folders:

app/controllers/my_devise
app/views/my_devise

Put all controllers that you want to override into app/controllers/my_devise and add MyDevise namespace to controller class names. Registrations example:

# app/controllers/my_devise/registrations_controller.rb
class MyDevise::RegistrationsController < Devise::RegistrationsController

  ...

  def create
    # add custom create logic here
  end

  ...    

end

Change your routes accordingly:

devise_for :users,
           :controllers  => {
             :registrations => 'my_devise/registrations',
             # ...
           }

Copy all required views into app/views/my_devise from Devise gem folder or use rails generate devise:views, delete the views you are not overriding and rename devise folder to my_devise.

This way you will have everything neatly organized in two folders.

In your form are you passing in any other attributes  via mass assignment that don t belong to your user model  or any of the nested models   If so  I believe the ActiveRecord  UnknownAttributeError is triggered in this instance   Otherwise  I think you can just create your own controller  by generating something like this     app controllers registrations controller rb class RegistrationsController  lt  Devise  RegistrationsController   def new     super   end    def create       add custom create logic here   end    def update     super   end end    And then tell devise to use that controller instead of the default with     app config routes rb devise for  users   controllers   gt    registrations   gt   registrations

Very simple methods Just go to the terminal and the type following  rails g devise controllers users   This will create devise controllers in controllers users folder   Next to use custom views   rails g devise views users   This will create devise views in views users folder   now in your route rb file  devise for  users  controllers                sessions   gt   users sessions               registrations   gt   users registrations      You can add other controllers too  This will make devise to use controllers in users folder and views in users folder   Now you can customize your views as your desire and add your logic to controllers in controllers users folder   Enjoy

You can generate views and controllers for devise customization   Use  rails g devise controllers users -c registrations   and  rails g devise views    It will copy particular controllers and views from gem to your application   Next  tell the router to use this controller   devise for  users   controllers   gt    registrations   gt   users registrations

I believe there is a better solution than rewrite the RegistrationsController  I did exactly the same thing  I just have Organization instead of Company    If you set properly your nested form  at model and view level  everything works like a charm   My User model   class User  lt  ActiveRecord  Base     Include default devise modules  Others available are       token authenticatable   confirmable   lockable and  timeoutable   devise  database authenticatable   registerable        recoverable   rememberable   trackable   validatable    has many  owned organizations   class name   gt   Organization    foreign key   gt   owner id    has many  organization memberships   has many  organizations   through   gt   organization memberships      Setup accessible  or protected  attributes for your model   attr accessible  email   password   password confirmation   remember me   name   username   owned organizations attributes    accepts nested attributes for  owned organizations       end   My Organization Model   class Organization  lt  ActiveRecord  Base   belongs to  owner   class name   gt   User    has many  organization memberships   has many  users   through   gt   organization memberships   has many  contracts    attr accessor  plan name    after create  set owner membership   set contract       end   My view    devise registrations new html erb    lt h2 gt Sign up lt  h2 gt    lt   resource owned organizations build if resource owned organizations empty    gt   lt    form for resource   as   gt  resource name   url   gt  registration path resource name   do  f    gt     lt    devise error messages    gt      lt p gt  lt    f label  name   gt  lt br   gt       lt    f text field  name   gt  lt  p gt      lt p gt  lt    f label  email   gt  lt br   gt       lt    f text field  email   gt  lt  p gt      lt p gt  lt    f label  username   gt  lt br   gt       lt    f text field  username   gt  lt  p gt      lt p gt  lt    f label  password   gt  lt br   gt       lt    f password field  password   gt  lt  p gt      lt p gt  lt    f label  password confirmation   gt  lt br   gt       lt    f password field  password confirmation   gt  lt  p gt      lt    f fields for  owned organizations do  organization form    gt        lt p gt  lt    organization form label  name   gt  lt br   gt         lt    organization form text field  name   gt  lt  p gt        lt p gt  lt    organization form label  subdomain   gt  lt br   gt         lt    organization form text field  subdomain   gt  lt  p gt        lt    organization form hidden field  plan name   value   gt  params  plan    gt      lt   end   gt      lt p gt  lt    f submit  Sign up    gt  lt  p gt   lt   end   gt    lt    render  partial   gt   devise shared links    gt
