Rails form_for edit not saving changes - ruby-on-rails

Question

I'm new to rails and having trouble getting my edit form to update attributes.
Here is my routes.rb for project and note:
resources :projects do
resources :notes
end
And this is my form_for in views/notes/edit.html.erb:
<%= form_for [#project, #note] do |f| %>
<div class="form-group">
<%= f.label :title %>
<%= f.text_field :title, class: "form-control" %>
</div>
<div class="form-group">
<%= f.label :body %>
<%= f.text_area :body, rows: 10, class: "form-control" %>
</div>
<div class="action">
<%= f.submit "Save Note", class: "btn btn-success" %>
</div>
<% end %>
And finally this is my notes_controller.rb:
class NotesController < ApplicationController
before_action :find_note, only: [:show, :edit, :update, :destroy]
def index
#notes = Note.all
end
def new
#project = Project.find(params[:project_id])
#note = #project.notes.new
end
def create
#project = Project.find(params[:project_id])
#note = #project.notes.build(note_params)
#note.project = #project
#note.save ? flash[:notice] = "Note created." : flash[:error] = "Note could not be created, please try again."
redirect_to [current_user, #project]
end
def show
end
def edit
end
def update
if #note.update_attributes(note_params)
#note.save
flash[:notice] = "Note updated."
redirect_to authenticated_root_path
else
flash[:error] = "Could not update note."
render :edit
end
end
def destroy
#note.delete ? flash[:notice] = "Note deleted." : flash[:error] = "Note could not be deleted."
redirect_to user_project_path
end
private
def note_params
params.require(:note).permit(:title, :body)
end
def find_note
#project = Project.find(params[:project_id])
#note = #project.notes.find(params[:id])
end
end
This is what my terminal is outputting:
Started GET "/projects/12/notes/13/edit?utf8=%E2%9C%93&_method=patch&authenticity_token=vnIoOSi0ksMNI7uU0aMnBpkTBWi75wy%2BYvbs3RxO5sPIbvFzDA30%2B32dJxurdcsiu9zsIpuDCR%2FARUamBRrYmg%3D%3D&note%5Btitle%5D=Transporter+Materials&note%5Bbody%5D=Star+dust%2C+data&commit=Save+Note" for 127.0.0.1 at 2015-05-25 08:38:16 -0700

Thanks in advance for any suggestions.

If you are using #project.notes.build(note_params).
No need of this #note.project = #project in create action
and in update
if you are using #note.update_attributes(note_params)
this is not required #note.save
and its better try to debug it using #note.update_attributes!(note_params)
it will give you why its not able to save.
<%= form_for [#project, #note], :url => project_note_path(#project,#note), :method => :put do |f| %>
