RailsController

Code to include within the controller modules.

###code A before action allows us to run some code before each other module has been done, this is good to return some data from active record or to check some authorization.

before_action :<function>, only: [:edit, :update, :destroy]
def <function>
   @<entity> = <Enitity>.find(params[:id])
   # check authorisiation
end

###code for apis

  def show
    @zombie = Zombie.find(params[:id])

    respond_to do |format|
      format.xml {render json: @zombie }
    end
  end

###Directing to views render action: '<viewname>' this is going to map to the view called status.html.erb redirect_to(<path>) or `redirect_to(, notice: "sorry can't do that")
