Question

I’m a complete Rails newbie and I have a Rails Question about controllers and actions. In my controller, I have an action named vote. The code is as follows.

def vote
  @item = Item.find(params[:id])
  @item.increment(:votes)
  @item.save
  render :action => show
end

I have a button on a “show” view that activates this action as follows

<%= button_to "Vote", :action => "vote", :id => @item.id, %>

My issue is that when the button is pressed, I don’t want the application to try going to /items/:id/vote. I just want the code executed, then return back to the show view. I really appreciate all the advice!

Answer 1

Check out redirect_to, at the end of this code simply call redirect_to with a url or a path to go to and the user will be sent wherever you like.

If this vote function is in the same controller as show you can do

def vote

    @item = Item.find(params[:id])
    @item.increment(:votes)
    @item.save

    redirect_to :action => 'show'

end

This would send them back to your show controller (I would also look into Rails path and url functions – they’re extremely helpful)
