Rails redirect_to https while keeping all parameters

Question

I'm redirecting to https like so:

redirect_to :protocol => 'https://', :status => :moved_permanently

However, the parameters don't go through like this. I can pass specific parameters through like this:

redirect_to :protocol => 'https://', :status => :moved_permanently, :param1 => params[:param1], :param2 => params[:param2]

How would I make it so that it just passes through every parameter on the url instead of having to explicitly declare each parameter?

With Rails 4.2 and above, passing the whole params hash will result in adding ?controller=foo&action=bar to the querystring. Instead, you should do this:

redirect_to protocol: 'https', params: request.query_parameters
