pins controller: pins_controller.rb

class pinscontroller < applicationcontroller respond_to :html, :xml, :json before_filter :authenticate_user!, except: [:index] before_action :set_pin, only: [:show, :edit, :update, :destroy] def index @pins = pin.all respond_with(@pins) end def show respond_with(@pin) end def new @pin = current_user.pins.new respond_with(@pin) end def edit @pin = current_user.pins.find(params[:id]) end def create @pin = current_user.pins.new(pin_params) @pin.save respond_with(@pin) flash[:success] = "pin created successfully!" end def update @pin = current_user.pins.find(params[:id]) @pin.update(pin_params) respond_with(@pin) flash[:success] = "pin updated successfully!" end def destroy @pin = current_user.pins.find(params[:id]) @pin.destroy respond_with(@pin) flash[:alert] = "pin deleted!" end private def set_pin @pin = pin.find(params[:id]) end def pin_params params.require(:pin).permit(:description) end end

pins model = pin.rb

class pin < activerecord::base validates :user_id, presence: true validates :description, presence: true has_attached_file :image, :path => ":rails_root/public/system/:attachment/:id/:style/:filename", :url => "/system/:attachment/:id/:style/:filename" validates_attachment :image, content_type: { content_type: ['image/jpeg', 'image/jpg', 'image/png' 'image/gif'] }, size: { less_than: 5.megabytes } belongs_to :user end

on def pin_params should add together permission image file; be:

def pin_params params.require(:pin).permit(:description, :image) end
