Rails 4 issue: No route matches [PATCH] “/book.17”

manpreet Best Answer 2 years ago

I am working on an edit page which works. However, when I click the save button to save the changes I make, in rails 4, I get the following message: No route matches [PATCH] "/book.17" Any advice on how to fix this? I have been researching for a while and believe that it has something to do with my routes and not directing to the right page. Just not sure how I should change it. I have tried using patch/put instead of get for my edit action or putting patch 'books#update' to update but get the same error message. Any help will be appreciated! Here is the code:

Controller:

class BooksController < ApplicationController

def new
 #@book = Book.all
 @book = Book.new 
 @authors = Author.all
end

def edit 
  @book = Book.find_by_id(params[:id])
  @authors = Author.all
end 

def update 
 @book = Book.find_by_id(params[:id])
  if @book.update_attributes(book_params)
   flash[:success] = "Book Updated!"
   redirect_to @book
  else
      render 'edit'
  end 
end 

Routes Page:

Rails.application.routes.draw do

root 'welcome#index'

get 'author' => 'authors#new'

get 'name' => 'authors#show'

get 'book' => 'books#new'

get 'show' => 'books#show'

patch 'edit' => 'books#update'

resources :authors

resources :books

Edit Page:

<div class="move">
<h1>Update a book entryh2>

<div class="row">
<div class="col-md-6 col-md-offset-3">

<%= form_for(@book)  do |f| %>
