UserImages类的源:
class UserImages < ActiveRecord::Base
belongs_to :imageable ,polymorphic: true
has_attached_file :avatar,
:styles => { :medium => "300x300>", :thumb => "125x125>" },

结束
两种获取URL都没有问题。。。。两者都很好。。。
区别只是因为回形针从URL的最后一部分生成文件名。。。
所以在第一个URL中
图片?类型=大
在第二个URL中
10478546_662150043867205_2640371404472615909_n.jpg?oh=cb2fe9d421fef3d7d2220bb48a2a36e2&oe=5418E8FB
我已经将回形针用来生成文件名的URL部分加粗了。。。。在这两种情况下,你不应该为文件名而烦恼。。。因为你可以做任何你想做的手术
您可以通过检查路径
public/images/users/:id
(回形针路径配置)来确保文件已上载。非常感谢您的澄清!:)是,图像按指定路径存储。名称文件具有散列格式,但没有文件扩展名:d8146a48c0f4fc3d916e57257c6270e91205ccbc它对图像的解析方式有点混淆:PYeah如果回形针无法计算出将发生的扩展名。。。如果该文件存在于该路径中,您可以将其打开。然后就可以用回形针了。
