如何找到由 Dragonfly with Cucumber/Capybara 生成的图像？

我似乎不知道如何得到这个使用生成的 URL 蜻蜓。它们看起来像这样： /media/BAh_some_long_string_AwIw/12_11_52_810_5x5.jpg?s=7e360000，其中 5x5.jpg 是我的文件名。我已经尝试过类似的东西： //img[@src="/media//#{image}?s=*"] 但它不起作用。有什么建议吗？ – Ramon Tayag 2 月 25 日 4:18

我遇到了类似的问题，甚至更糟 - 就我而言，生成的图像路径甚至不包含（jpg | png | gif）文件名，它们只有这些非常长的ID：（

<img src="/media/BAhbB1sHOgZmSSIdNGQ4MTEyOGU3ZjViZmQwZTQ4MDAwMDAyBjoGRVRbCDoGcDoKdGh1bWJJIg0yMDB4MjAwIwY7BlQ" />

使用蜻蜓与mongo / gridfs）

这些路径渲染得很好，但我不知道如何找到他们在黄瓜/水豚步骤中：P

有什么想法吗？我查看了 Dragonfly 的功能，但它们只测试图像的渲染本身，而不检测它是否存在于 html 页面中。

In the comments to the solution for How do I find an image on a page with Cucumber/Capybara, somebody asked:

I can't seem to figure how to get this
to work with URLs generated by
Dragonfly. They look like this:
/media/BAh_some_long_string_AwIw/12_11_52_810_5x5.jpg?s=7e360000, where 5x5.jpg is my file name. I've
tried something like:
//img[@src="/media//#{image}?s=*"]
but it doesn't work. Got any tips? – Ramon Tayag Feb 25 at 4:18

I have a similar problem, only worse - in my case, the generated image paths don't even include a (jpg|png|gif) file name, they only have these really long ids:

<img src="/media/BAhbB1sHOgZmSSIdNGQ4MTEyOGU3ZjViZmQwZTQ4MDAwMDAyBjoGRVRbCDoGcDoKdGh1bWJJIg0yMDB4MjAwIwY7BlQ" />

(Using dragonfly with mongo/gridfs)

These paths get rendered alright, but I can't figure out how to find them in a Cucumber/Capybara step :P

Any ideas? I looked at the Dragonfly's features, but they only test the rendering of the image itself, without detecting it's existence within an html page.

在与 Dragonfly 的作者交谈之后回答我自己的问题（他正在努力使这变得更容易）：

#route
match '/media/:dragonfly/:file_name', :to => Dragonfly[:images]  

#model
class Store
  include MongoMapper::Document
  key :photo_uid, String
  key :photo_name, String
  image_accessor :photo
end

#view
<%= image_tag @store.photo.thumb('274x207#').url(:suffix => "/#{@store.photo_name}") if @store.photo %>

#cucumber
Then I should see the image "my_photo.png"

Then /^I should see the image "(.+)"$/ do |image|  
  page.should have_xpath("//img[contains(@src, \"#{image}\")]")
end

关键是将 [attachment]_name 字段添加到模型中，Dragonfly 会自动填充该字段，然后将其作为后缀传递给 url()。除了生成的蜻蜓标识符之外，路由还需要允许 :file_name 参数。

Answering my own question, after talking to Dragonfly's author (he's working on making this easier):

#route
match '/media/:dragonfly/:file_name', :to => Dragonfly[:images]  

#model
class Store
  include MongoMapper::Document
  key :photo_uid, String
  key :photo_name, String
  image_accessor :photo
end

#view
<%= image_tag @store.photo.thumb('274x207#').url(:suffix => "/#{@store.photo_name}") if @store.photo %>

#cucumber
Then I should see the image "my_photo.png"

Then /^I should see the image "(.+)"$/ do |image|  
  page.should have_xpath("//img[contains(@src, \"#{image}\")]")
end

The key is adding an [attachment]_name field to the model, which Dragonfly populates automatically, and then passing it on as a suffix to url(). And the routes needs to allow for a :file_name param besides the generated dragonfly identifier.
