Rails 4.1变体不起作用

Question

I'm trying to use actionpack Variants in my rails 4.1 website.

I'm following the rails guide, but it doesn't work.

In my application controller

before_action :set_request_variant

  private 

  def set_request_variant
    request.variant = :mobile if browser.mobile?
  end

I have Browser gem, and with iPhone user agent it return true so everything here is ok.

In my controller

  def show
    @event = Event.find params[:id]
    respond_to do |format|
      format.html
      format.html.mobile 
    end
  end

I have an application+mobile.html.haml and a _header+mobile.html.haml but the server serves always the standard layout and standards views...

Any idea?

Answer 1

I think your layout and view template names might be the problem. Does it work if you try application.html+phone.haml and _header.html+mobile.haml instead?

The format I've suggested is consistent with the Rails 4.1 release notes here .
