Rails: number_field isn't showing up when outputting a form?

I have a basic form at the moment, I inserted a it has a title, body and a number_field. All three of them are working it seems, except when I go to my index to view the posts only the title and body show up, no number.

the controller: class AuctionsController < ApplicationController

  def index
    @auctions = Auction.all
  end

  def new
    @auctions = Auction.new
  end

  def create
    @auctions = Auction.new(auction_params)
    if @auctions.save
      redirect_to auctions_path
    else
      render "new"
    end
  end


  def destroy
    @auctions = Auction.find(params[:id])
    @auctions.destroy
    redirect_to auctions_path
  end


  private
  def auction_params
    params.require(:auction).permit(:title, :details)
  end

end

_form.html.erb

<%= form_for Auction.new do |f| %>
  <%= f.text_field :title %> <br>
  <%= f.text_area :details %> <br>
  <%= f.number_field :price %> <br>
  <%= f.submit "Submit" %>
<% end %>

and my index.html.erb

<% @auctions.each do |auction| %>
  <%= auction.title %> <br>
  <%= auction.details %> <br>
  <%= auction.price %> <br>
  <%= link_to "Delete", auction, :method => :delete %> 
<% end %>

You forgot to permit the price in your strong params helper method, try this:

  def auction_params
    params.require(:auction).permit(:title, :details, :price)
  end

Your price value was never saved, so that's why it's not showing up. Try saving it again after these changes and it should work!
