Rails - How To Destroy Users Created Under Devise?

Question

For my application, I have user accounts that people can sign up. I use the devise gem for the setup.

I also have a users page that lists out all the u

Answer 1

At least the latest version of Devise does provide such functionality out of the box, if a Devise-backed model has :registerable included.

class User < ApplicationRecord
  devise :database_authenticatable, :registerable
end

Somewhere in app/views/layouts/application.html.erb:

<%= link_to 'Delete my account', user_registration_path, method: :delete if user_signed_in? %>

Answer 2

According to devise 4.1 rake routes and views, using the following will help you delete the account once logged in as a user.

<%= link_to "Cancel my account", registration_path(current_user), data: { confirm: "Are you sure?" }, method: :delete %>

Answer 3

Devise doesn't provide this functionality out of the box. You have created your own destroy action, but you also have to create a custom route to that action.

In your routes:

 match 'users/:id' => 'users#destroy', :via => :delete, :as => :admin_destroy_user

And then when creating the link:

<%= link_to "Destroy", admin_destroy_user_path(user), method: :delete, data: { confirm: "You sure?" } %>

Answer 4

Or from rails c you can do something like this where "x" is user id.

user = User.where(id: x)
user.destroy(1) 

Answer 5

I think you have in your routes.rb: resources :users

The problem is that you are not passing the user that you want to delete when clicking:

users/_user.html.erb

<%= link_to "Destroy", user, method: :delete, data: { confirm: "You sure?" } %>

See that in second param I added user instead of user_url.

users_controller.rb

 def destroy
    @user = User.find(params[:id])

    if @user.destroy
        redirect_to root_url, notice: "User deleted."
    end
  end

In controller I removed an @user.destroy. You were calling it twice.

Hope it helps!
