Delete a row of data with a destroy button in Ruby - ruby-on-rails

Question

I have an index of all items from database listed in my view. I want to create a destroy button to destroy the current record in the database using Ruby on Rails 4. Here is my code:
<div>
<h1>All Incomes</h1>
<% #user_incomes.each do |income| %>
<div>
<p><%= income.title %></p>
<p><%= income.description %></p>
<p><%= number_to_currency(income.amount) %>
<p><%= income.user_id %></p>
<%= button_to "Destroy", {action: "destroy", id: income.id}, method: :destroy, data: { confirm: "Are you sure?" } %>
</div>
<br />
<%end%>
</div>
My Income Controller:
class IncomesController < ApplicationController
before_action :authorize, only: [:new, :index, :show, :create]
def index
#incomes = Income.all #income refers to the db model income
#user_incomes = Income.all.where(:user_id=>current_user.id)
end
def show
#income = Income.find(params[:id])
end
def new
#income = Income.new
end
def create
#income = Income.create(income_params)
end
def destroy
#income.destroy
end
## Strong Parameters alias Rails 3's attr_accessible
private
def income_params
params.require(:income).permit(:title, :user_id, :description, :type, :amount)
end
def declare_income
#income = Income.find(params[:id])
end
end
Here is my route file:
Rails.application.routes.draw do
get 'member_content/new'
#get 'sessions/new' ## this is generated with rails g controller sessions new
resources :sessions
resources :incomes
resources :users
resources :abl_deductions
get 'main/index'
# Example of regular route:
# get 'products/:id' => 'catalog#view'
get 'signup', to: 'users#new', as: 'signup'
get 'login', to: 'sessions#new', as: 'login'
get 'logout', to: 'sessions#destroy', as: 'logout'
get 'content', to: 'member_content#new', as: 'content'
get 'add_income', to: 'incomes#new', as: 'add_income'
get 'add_deduction', to: 'abl_deductions#new', as: 'add_deduction'
get 'deductions', to: 'abl_deductions#index', as: 'deductions'
end
I am newb to rails, would it be easier for this action if I had use a scaffold with rails generate scaffold?

Answer 1

Let's assume your controller is called IncomesController. When you run bin/rails routes in your app folder, you should also see something like:
DELETE /incomes/:id(.:format) incomes#destroy
To achieve this, you need to have proper routes.rb records. Easy thing to achieve standard CRUD operations over incomes is to have resources :incomes in routes.rb
You also need to have destroy method in IncomesController to perform actual destroy.
