Yes, you can. If you have the respond_to block in the controller, then anything you put inside the block can do whatever it wants to. Here's one from a controller I made some time ago with the scaffold generator:

def update
respond_to do |format|
if @country.update(country_params)
format.html { redirect_to @country, notice: 'Country was successfully updated.' }
format.json { render :show, status: :ok, location: @country }
else
format.html { render :edit }
format.json { render json: @country.errors, status: :unprocessable_entity }
end
end
end

Only one block will respond to the action here, depending on the format and the result of #update. So this won't violate the single render/redirect constraint on controller method.

At the Ruby level, this is just a block inside a block.
