Redirection in ruby on rails

I am a beginner in ruby on rails. So the scenario is that I am in an index page and I am performing an update in a form displayed on that page. Once the update is done I wish to redirect it back to the index page and reflect the update. i tried this,

 def update
    format.html { redirect_to action: "index"}
  end

This does not seem to work. Any place I am going wrong?

It does not work, becuase format is not defined. Either use

def update
  # some logic...
  respond_to do |format|
    format.html { redirect_to action: "index"}
  end
end

or drop respond_to and leave just:

def update
  # some logic...
  redirect_to action: "index"
end

respond_to is a method that lets you define how your controller action will respond to given format, e.g:

def update
  # some logic...
  respond_to do |format|
    format.html { redirect_to action: "index"}
    format.json { render json: {bleh: :blah} }
  end
end
