Ruby on Rails "Couldn't find Customer with 'id'=links" - ruby-on-rails

Question

I want to have a page that displays links to other websites in my project. I created links.html.erb in my customers views but when I try access the page I get this error.
ActiveRecord::RecordNotFound in CustomersController#show
Couldn't find Customer with 'id'=links
Customers Controller:
class CustomersController < ApplicationController
before_action :set_customer, only: [:show, :edit, :update, :destroy]
before_action :authenticate_user!
# GET /customers
# GET /customers.json
def index
#customers = Customer.all
#q = Tour.search(params[:q])
#tours = #q.result.page(params[:page]).per(5)
#q.build_condition if #q.conditions.empty?
#q.build_sort if #q.sorts.empty?
end
def links
end
# GET /customers/1
# GET /customers/1.json
def show
#customers = Customer.all
end
def welcome
end
# GET /customers/new
def new
#customer = Customer.new
end
# GET /customers/1/edit
def edit
end
# POST /customers
# 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
# PATCH/PUT /customers/1
# PATCH/PUT /customers/1.json
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
# DELETE /customers/1
# DELETE /customers/1.json
def destroy
#customer.destroy
respond_to do |format|
format.html { redirect_to customers_url, notice: 'Customer record successfully deleted' }
format.json { head :no_content }
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(:name, :address, :telephone_no, :ticket_number)
end
end
Routes:
Rails.application.routes.draw do
devise_for :admin_users, ActiveAdmin::Devise.config
ActiveAdmin.routes(self)
resources :customers
resources :tours
devise_for :users
root 'customers#welcome'
In view:
<% if current_user.customer? %>
<div class="col-sm-4">
<%= link_to image_tag("image1.jpg", size: "300x300"), {:controller => 'customers', :action => "links" } %>
<h3>Links</H3>
</div>
<% end %>
Anyone help with what is wrong here? Thanks.

Answer 1

Add get 'links' => 'customers#links', as: :link to the routes.rb and update your link as:
<%= link_to image_tag("image1.jpg", size: "300x300"), link_path %>

Answer 2

Here's a bit of an expansion on Ganesh's answer.
When you do this:
<%= link_to image_tag("image1.jpg", size: "300x300"), {:controller => 'customers', :action => "links" } %>
You're creating a url to:
customers/links
In your routes, the first match for customers/links is customers/:id which routes to customers/show with params[:id] = 'links'. See the Guide if you don't understand why this is true. That's why you're getting the error:
ActiveRecord::RecordNotFound in CustomersController#show
Couldn't find Customer with 'id'=links
As Ganesh correctly points out, you can coerce the routes exactly as he says. To me, it is a little smelly to put this links page in the CustomerController and to coerce the routes. But, that's really a design decision based on the problem(s) you're trying to solve.
