Ruby on Rails: How can I use a redirect_to in a link_to?

I want to redirect to a certain page after an action (handled by a开发者_运维技巧 gem) is finished.

Redirects are handled in the controller.

Example:

def update
  @model.save
  redirect_to model_path(@model)
end

you can do this in 3 ways

1) using render :action

def update @model.save render :action => "page_name" end here it will take you on "page_name" page

2) render :template => "page_name" here it will take you on "page_name" page

3) using redirect_to
