Products controller 产品控制器
class ProductsController < ApplicationController
def new
@product = Product.new
@photo = Photo.new
end
def create
@photo = current_user.photos.build(params[:photo])
5.times { @product.photos.build }
@product = current_user.products.build(params[:product])
if @product.save
render "show", :notice => "Sale created!"
else
render "new", :notice => "Somehting went wrong!"
end
end
Product model 产品型号
class Product < ActiveRecord::Base
attr_accessible :description, :name, :price, :condition, :ship_method, :ship_price, :quantity, :photo
has_attached_file :photo
belongs_to :user
validates :user_id, presence: true
validates :name, presence: true, length: { minimum: 5 }
end
Photo model 照片模型
class Photo < ActiveRecord::Base
attr_accessible :product_id
belongs_to :product
has_attached_file :image,
:styles => {
:thumb=> "100x100#",
:small => "300x300>",
:large => "600x600>"
}
end
The syntax isn't correct - change: 语法不正确 - 更改:
= f.file_field :product.photo, multiple: 'multiple'
To: 至:
= f.file_field :photo, multiple: 'multiple'
