how to display individual listings? Ruby on Rails - ruby-on-rails

Question

I am currently working on a simple website where people can list postings. Most of the code is based on Michael Hartl's tutorial.
I want users to have the ability to click on a link that displays the listing individually.
currently, the listings' of each user are found under
http://localhost:3000/users/id
Every listing has it's own id
Here are my routes
Rails.application.routes.draw do
resources :users
resources :sessions, only: [:new, :create, :destroy]
resources :listings
root 'static_pages#home'
match '/signup', to: 'users#new', via: 'get'
match '/signin', to: 'sessions#new', via: 'get'
match '/signout', to: 'sessions#destroy', via:'delete'
match '/help', to: 'static_pages#help', via: 'get'
match '/contact', to: 'static_pages#contact', via: 'get'
match '/about', to: 'static_pages#about', via: 'get'
match '/new', to: 'listings#new', via: 'get'
Here is my listing_controller.rb
class ListingsController < ApplicationController
before_action :signed_in_user, only: [:create, :destroy, :edit]
before_action :correct_user, only: :destroy
def create
#listing = current_user.listings.build(listing_params)
if #listing.save
flash[:success] = "Job Post created"
redirect_to current_user
else
render 'listings/new'
end
end
def edit
end
def show
#listing = Listing.find(params[:id])
end
def new
#listing = Listing.new
#listings = Listing.paginate(page: params[:page])
end
def destroy
#listing.destroy
redirect_to current_user
end
private
def listing_params
params.require(:listing).permit(:description, :location, :title)
end
def correct_user
#listing = current_user.listings.find_by(id: params[:id])
redirect_to current_user if #listing.nil?
end
def current_listing
#listings = listing.find(params[:id])
end
end
I also created a show page for each listing under listings the listings folder.
The show page itself works.
Here is the show.html.erb for the listing
<div class="show_listing">
<div class="col-md-6">
<div class="col-md-6">
<h3><%= #listing.title %></h3>
<h3><%= #listing.location %></h3>
<p><%= #listing.description %></p><br>
<div class="center">
<%= link_to "Apply Now", '#', class: "btn btn-info", data: {no_turbolink: true} %>
</div>
</div>
</div>
</div>
<div class="show_link_position">
<% if current_user == #listing.user %>
<%= link_to 'Edit', '#', class: "btn btn-link" %> |
<% end %>
<%= link_to 'Back', current_user, class: "btn btn-link" %>
</div>
Now I would like to have a link on the user page (under each listing) that would link to each post individually.
I'm looking for something like this

Thank you
Let me know if you need more information

Answer 1

To create a link from a page where you have the collection of listings as #listings, you might have something like this...
<ol class="listings">
<% #listings.each do |listing| %>
<div class="listing">
<h2><%= listing.title</h2>
<h3><%= listing.location</h3>
<p><%= listing.description</p>
<%= link_to "Show", listing, class: "btn btn-link" %>
</div>
<% end %>
</ol>

Answer 2

Here is what I did to get it to work (with the help of the following stackoverflow post how to display a link to individual microposts? (ruby on rails 3))
Routes rb.
match '/users/:id/:id', to 'listings#show', via: :get, as: :user_listing
users view file
add the link
<li><%= link_to "Show", user_listing_path(id: #user.id, id: listing.id) %></li>
Changed my listing_controller file
def show
#user = User.find_by_id(params[:id])
#listing = Listing.find_by_id(params[:id])
end
