Ruby On Rails Basic Show method failed still - ruby-on-rails

Question

In this block of code, i want to put a button "edit" inside the "show" views. However, due to some reason, it did not works out
My home_controller.rb
class HomeController < ApplicationController
def index
#inputs = Person.all
end
def new
#input = Person.new
end
def create
#input = Person.new(input_params)
respond_to do |x|
if #input.save
x.html {redirect_to :action => 'index'}
else
x.html {render :action => 'new'}
end
end
end
def show
#input = Person.find(params[:id])
end
def edit
#input = Person.find(params[:id])
end
def update
#input = Person.find(params[:id])
respond_to do |x|
if #input.update(input_params)
x.html {redirect_to :action => 'index'}
else
x.html {render :edit}
end
end
end
private
def input_params
params.require(:inputs).permit(:name, :weight, :height, :color, :age)
end
end
My routes file only have two lines:
resources: home
root 'home#index'
My index.html.erb
<p id="notice"><%= notice %></p>
<h1>Listing</h1>
<table>
<thead>
<tr>
<th>Name</th>
<th> Weight</th>
<th> Height</th>
<th> Color</th>
<th> Age</th>
<th colspan="3"></th>
</tr>
</thead>
<tbody>
<% #inputs.each do |person| %>
<tr>
<td><%= person.name %></td>
<td><%= person.weight %></td>
<td><%= person.height %></td>
<td><%= person.color %></td>
<td><%= person.age %></td>
<td><%= link_to 'Show',home_path(person.id) %></td>
<td><%= link_to 'Edit', edit_home_path(person.id) %></td>
</tr>
<% end %>
</tbody>
</table>
<br>
<%= link_to 'New Test', new_home_path %>
my show.html.erb:
<p>
<strong>Name:</strong>
<%= #input.name %>
</p>
<p>
<strong>Weight:</strong>
<%= #input.weight %>
</p>
<p>
<strong>Height:</strong>
<%= #input.height %>
</p>
<p>
<strong>Color:</strong>
<%= #input.color %>
</p>
<p>
<strong>Age:</strong>
<%= #input.age %>
</p>
<% link_to 'Edit', edit_home_path(#input) %>
<%= link_to 'Back', home_index_path%>
My form.html.erb
<%= form_for #input, url: {action: "update"} do |person| %>
<div class="field">
<%= person.label :name %><br>
<%= person.text_field :name %>
</div>
<div class="field">
<%= person.label :weight %><br>
<%= person.number_field :weight %>
</div>
<div class="field">
<%= person.label :height %><br>
<%= person.number_field :height %>
</div>
<div class="field">
<%= person.label :color %><br>
<%= person.text_field :color %>
</div>
<div class="field">
<%= person.label :age %><br>
<%= person.number_field :age %>
</div>
<div class="actions">
<%= person.submit %>
</div>
<% end %>
My edit.html.erb
<h1>Editing Data</h1>
<%= render 'form' %>
<%= link_to 'Show', home_path %> |
<%= link_to 'Back', home_index_path %>
The error i get is:
My code <% link_to 'Edit', edit_home_path(#input) %> is point the Edit button to the route home/edit with the obeject #input, that is how i understand it, but it still not working.
Any idea how can i fix this?
Many thanks

The problem is in your show.html.erb. You need to change #person to #input as you have #input defined in your show method
