📝 Blog Post: Override Devise Registrations Controller

Hey there tech enthusiasts! Welcome back to another awesome blog post where we tackle tech dilemmas with style and ease. Today, we're diving into the world of Devise and overcoming the common issue of overriding the registrations controller. Let's get right into it!

🔎 Identifying the problem

So, you've added a fancy new field to your sign-up form, but things aren't going as smoothly as you'd hoped. Upon hitting that save button, an ominous Activerecord::UnknownAttributeError pops up, pointing directly at the newly added field (in this case, "company"). Don't stress, we've got your back!

🔄 Why would you want to override the registrations controller?

Now, you may be wondering why on earth you would need to override the registrations controller. Well, in certain scenarios, like yours, where additional customizations are required, overriding the default controller becomes essential. It allows you to take control and tailor the sign-up process to your exact needs.

🛠️ Easy solution: Overriding the Devise Registrations Controller

To override the registrations controller, follow these steps:

1. Create a new file in your controllers directory (if it doesn't exist already) named registrations_controller.rb. This will be your customized registrations controller.

2. Open the newly created file and define the class RegistrationsController which inherits from Devise::RegistrationsController. Your code should look something like this:

   class RegistrationsController < Devise::RegistrationsController # Your custom code goes here end

3. Now, we'll specifically address the issue with the "company" field causing the UnknownAttributeError. Override the sign_up_params method inside your RegistrationsController and permit the "company" attribute. Here's an example:

   class RegistrationsController < Devise::RegistrationsController private def sign_up_params params.require(:user).permit(:email, :password, :password_confirmation, :company) end end

4. Almost there! We need to inform Devise to use our customized registrations controller instead of the default one. Add the following line at the bottom of your routes.rb file:

   devise_for :users, controllers: { registrations: 'registrations' }

📢 Time for action!

It's showtime, folks! Fire up your sign-up form, fill in all the required details, including the fantastic "company" field, and hit that glorious save button. 🚀
