    def set_properties 
 
     @property = Property.find(params[:id]) 
 
    end 
 

 
    # Never trust parameters from the scary internet, only allow the white list through. 
 
    def properties_params 
 
     params.require(:property).permit(:Space_name,:user_id,:address,:pincode,:image,property_dates_attributes: [ :start_date, :end_date ])
