Ruby on Rails

In the delete link, you need to use the delete method-Rails now expects a delete verb, where as your code is generating a get I believe
So
<%= link_to 'Delete', :controller => "people", :action
=> "destroy", :id => e, :method => :delete %>

Hello, thanks to you I have been able to add in the data. I also changed
and cleaned up the code and used the convention with regards to the
variables. I have another question regarding the destroy/deleting data,
when I click on delete, it directs me to show where i can view the data,
but does not delete anything. Here is my updated code
peoplecontroller:
class PeopleController < ApplicationController
def index
@people = Person.all
end
def show
@person = Person.find(params[:id])
end
def new
@person = Person.new
end
def create
@person = Person.new(person_params)
@person.save
redirect_to :action => :index
end
def edit
@person = Person.find(params[:id])
end
def update
@person = Person.find(params[:id])
@person.update(person_params)
redirect_to :action => :show, :id => @person
end
def destroy
@person = Person.find(params[:id])
@person.destroy
redirect_to :action => :index
end
private
def person_params
params.require(:person).permit(:name, :weight, :height, :color,
:age)
end
end

index:
<h1> People list</h1>
<table>

<tr>
<th>Name</th>
<th> Weight</th>
<th> Height</th>

<% @people.each do |e| %>

<% end %>

<%= link_to 'New Input', :controller => 'people', :action => 'new' %>
