Ruby On Rails Basic Show method failed still

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: It suppose to give me a Edit button, but actually it did not show up, confused

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
