Question

这是upload.rb（模型）

class Upload < ActiveRecord::Base
belongs_to :post
has_attached_file :name, :styles => { :medium => ["600x400>",:jpg], :thumb => ["122x122>",:jpg]}, url: "/post_images/post_:post_id/:style/:filename"

def self.image_url
    "/post_images/post_:post_id/medium/:filename"
end

end

如何获取上传文件的网址。

我的控制器：

def img_upload
    @image = Upload.new post_id: post_id, name: params[:Filedata]
        if @image.save
          render json: Upload.image_url
        end
end

任何人都可以帮助我。

Answer 1

在您的控制器中

path = @upload.name.url

您只需致电url附件

即可

对于拇指网址，只需添加(:thumb)

即可

path = @upload.name.url(:thumb)

一旦上传，Rails回形针就会上传图像路径
