I have seem this question posted before but the normal "add :content to model" doesn't work for my situation. I have already added it and the error still occurs.

This a modified version of a codecademy project if it looks familiar.

Model

 class CreateNotes < ActiveRecord::Migration
    def change
      create_table :notes do |t|
        t.text :content
        t.timestamps
      end
    end
 end

Controller

class NotesController < ApplicationController
    def index
       @notes = Note.all
    end

    def new
       @note = Note.new
    end

    def create
       @note = Note.new(note_params)
           if @note.save
               redirect_to '/notes'
           else
               render 'new'
           end
    end

    private
    def note_params
       params.require(:note).permit(:content)
    end
end

Route

Rails.application.routes.draw do

     root 'notes#index'
     get "notes" => "notes#index"
     get "notes/new" => "notes#new"
     post "notes" => "notes#create"

index.html.erb

<div class="header">
  <div class="container">
    <h1>Notes</h1>
  </div>
</div>

<div class="notes">
  <div class="container">

    <% @notes.each do |note| %>
        <div class="note">
        <p class="content"><%= note.content %></p>
        <p class="time"><%= note.created_at %></p>
        </div>
    <% end %>
    <%= link_to 'New Note', "notes/new" %>

  </div>
</div>

new.html.erb

<div class="header">
  <div class="container">
    <h1>Notes</h1>
  </div>
</div>

<div class="create">
  <div class="container">

    <%= form_for(@note) do |f| %>
        <div class="field">
            <%= f.label :note %><br>
            <%= f.text_area :content %>
        </div>
        <div class="actions">
            <%= f.submit "Create" %>
        </div>
        <% end %>
  </div>
</div>

If anyone can figure out why I am still getting this error after :content is already in the model, that would be awesome!

P.S. First post so sorry if it is terrible.
