Update child attributes rails - ruby-on-rails

Question

I have a customer model and book_room model
class Customer < ApplicationRecord
has_many :book_rooms
accepts_nested_attributes_for :book_rooms
end
class BookRoom < ApplicationRecord
belongs_to :customer
end
in the book_room controller the create method is from its parent
class BookRoomsController < ApplicationController
def create
#customer = Customer.find(params[:customer_id])
#customer_room = #customer.book_rooms.create(book_rooms_params)
flash[:notice] = "Customer has been added to room"
redirect_to customer_path(#customer)
end
def destroy
#customer = Customer.find(params[:customer_id])
#customer_room = #customer.book_rooms.find(params[:id])
#customer_room.destroy
flash[:notice] = "Customer room has been deleted"
redirect_to customer_path(#customer)
end
def edit
#customer = Customer.find(params[:customer_id])
end
def update
#customer = Customer.find(params[:customer_id])
#customer.book_rooms.update(book_rooms_params)
flash[:notice] = "Customer has checked out"
redirect_to #customer
end
private
def book_rooms_params
params.require(:book_room).permit(:room, :first_name, :last_name, :phone_number, :checked_out)
end
end
in the Customer show page
<%= form_for [#customer, #customer.book_rooms.build] do |f| %>
<% #room = Room.all %>
<%= f.label "Room: "%>
<%= f.select(:room, #room.collect { |a| [a.room_number, a.id] }) %>
<%= f.submit "Enter" %>
<div class="col-md-12"><%= render #customer.book_rooms.order("created_at DESC") %></div>
This works perfectly and all child objects get created. now when I try to edit the child attributes it doesn't update at all
heres the edit form in the book_room edit page/action
<%= form_for #customer do |f| %>
<%= f.fields_for :book_rooms, #customer.book_rooms do |f| %>
<%= f.check_box :checked_out %>
<% end %>
<%= f.submit "Enter" %>
is there something i am doing wrong? why doesn't it update?
Customers controller
class CustomersController < ApplicationController
before_action :set_customer, only: [:show, :edit, :update, :destroy]
# POST /customers.json
def create
#customer = Customer.new(customer_params)
respond_to do |format|
if #customer.save
format.html { redirect_to #customer, notice: 'Customer was successfully created.' }
format.json { render :show, status: :created, location: #customer }
else
format.html { render :new }
format.json { render json: #customer.errors, status: :unprocessable_entity }
end
end
end
def update
respond_to do |format|
if #customer.update(customer_params)
format.html { redirect_to #customer, notice: 'Customer was successfully updated.' }
format.json { render :show, status: :ok, location: #customer }
else
format.html { render :edit }
format.json { render json: #customer.errors, status: :unprocessable_entity }
end
end
end
private
# Use callbacks to share common setup or constraints between actions.
def set_customer
#customer = Customer.find(params[:id])
end
# Never trust parameters from the scary internet, only allow the white list through.
def customer_params
params.require(:customer).permit(:first_name, :last_name, :phone_number, :sex, :book_rooms_attributes => [:checked_out])
end

Answer 1

In your customers controller :
Try to change your function customer_params like:
def customer_params
params.require(:customer).permit(:first_name, :last_name, :phone_number, :sex, {:book_rooms => [:checked_out]})
end
For more explications see here

Answer 2

Change your update method to:
def update
#customer = Customer.find(params[:customer_id])
if #customer.update_attributes(customer_params)
flash[:notice] = "Customer has checked out"
redirect_to #customer
else
...redirect to edit page with a flash error message ...
end
end
You also need to modify your edit page.
<%= form_for(:customer, :url => {:action => 'update', :id => #customer.id}, :method => 'PUT') do |f| %>

Answer 3

Try changing the URL to update and changing the method to patch you will go to update method.
<%= form_for :customer, url: customer_path(#customer),method: :patch do |f| %>
<%= f.fields_for :book_rooms, #customer.book_rooms do |f| %>
<%= f.check_box :checked_out %>
<% end %>
<%= f.submit "Enter" %>
