How to combine a <div> with a Rails "link_to"? - ruby-on-rails

Question

I am creating a "to-do website". Users can log in and generate tasks as well as notes. The tasks work perfectly but I have some issues with notes for some reason. I don't use any partials for notes. If I use this on my index.html.erb as I did for the tasks:
<div class="notes">
<%= link_to 'New Note', new_note_path %>
<div class="note">
<div>
<%= link_to note_path(note) do %>
<%= note.content %>
<%= link_to 'X', note, :class => 'task-destroy', method: :delete, data: {confirm: 'Are you sure?'} %>
<% end %>
</div>
<div>
<%= link_to edit_note_path(note) do %>
<%= time_ago_in_words(note.updated_at) %> ago
<% end %>
</div>
</div>
</div>
I get:
"NameError in NotesController#index" - "undefined local variable or
method `note' for #..."
notes_controller.rb
class NotesController < ApplicationController
before_action :logged_in_user
before_action :set_note, only: [:show, :edit, :update, :destroy]
def index
#notes = current_user.notes
end
def show
end
def new
#note = Note.new
end
def edit
end
def create
#note = current_user.notes.new(note_params)
if #note.save
flash[:success] = "You successfully created a Note!"
redirect_to notes_path
else
render 'new_note_path'
end
end
def update
#note.update(note_params)
if #note.save
flash[:success] = "You successfully updated a Note!"
redirect_to notes_path
else
render 'edit_note_path'
end
end
def destroy
#note.destroy
flash[:success] = "You successfully deleted a Note!"
redirect_to notes_path
end
private
def set_note
#note = Note.find(params[:id])
end
def note_params
params.require(:note).permit(:content)
end
end
Question: What is wrong with my instance variable on my controller and how can I make it work?

Answer 1

add loop before <div class="note"> to loop through list of notes stored in #notes in your index action.
Html should look like this:
<% #notes.each do |note| %>
<div class="note">
<div>
<%= link_to note_path(note) do %>
<%= note.content %>
<%= link_to 'X', note, :class => 'task-destroy', method: :delete, data: {confirm: 'Are you sure?'} %>
<% end %>
</div>
<div>
<%= link_to edit_note_path(note) do %>
<%= time_ago_in_words(note.updated_at) %> ago
<% end %>
</div>
</div>
</div>
<% end %>

Answer 2

Your index.html.erb view doesn't have access to a note variable.
The instance variable from the following method is the only variable being passed to the view:
def index
#notes = current_user.notes
end
You would probably need to do something like,
<% #notes.each do |n| >
<%= link_to(n) >
<% end >
