flickr-fu 简单示例不起作用
我在 Rails 应用程序中使用 flickr-fu gem 进行 flickr api 集成。我按照如下所示的设置 Web 应用程序的示例代码进行操作：
def flickr_create
flickr = Flickr.new(File.join(RAILS_ROOT, 'config', 'flickr.yml'))
redirect_to flickr.auth.url(:read)
end
def flickr_callback
flickr = Flickr.new(File.join(RAILS_ROOT, 'config', 'flickr.yml'))
flickr.auth.frob = params[:frob]
current_user.update_attribute :flickr_token, flickr.auth.token.token
flash[:notice] = "Succesfully authenticated with Flickr"
redirect_to :flickr_stream
end
我已将 flickr_callback 注册为 flickr 在授权过程后调用的回调方法。
当我尝试将 params[:frob] 分配给 flickr.auth.frob 时，问题出在 flickr_callback 中的行。我收到以下错误：
Flickr::Auth:0x24b3640 的未定义方法“frob=”
即使我只需要从控制台中调用'flickr_fu'，创建一个新的 flickr 实例，并尝试分配给 frob，我也会得到同样的错误。我查看了github上的gem源代码，setter frob=是在Flickr::Auth模块中设置的，所以我不知道错误在哪里。 API 调用成功，flickr 对象初始化正常。
I'm using flickr-fu gem within a rails application for flickr api integration. I'm following the sample code for setting up a web app shown below:
def flickr_create
flickr = Flickr.new(File.join(RAILS_ROOT, 'config', 'flickr.yml'))
redirect_to flickr.auth.url(:read)
end
def flickr_callback
flickr = Flickr.new(File.join(RAILS_ROOT, 'config', 'flickr.yml'))
flickr.auth.frob = params[:frob]
current_user.update_attribute :flickr_token, flickr.auth.token.token
flash[:notice] = "Succesfully authenticated with Flickr"
redirect_to :flickr_stream
end
I've registered flickr_callback as the callback method that flickr calls after the authorization process.
The problem is with the line in flickr_callback when I try and assign params[:frob] to flickr.auth.frob. I get the following error:
undefined method `frob=' for Flickr::Auth:0x24b3640
Even if I just require 'flickr_fu' from within console, create a new flickr instance, and attempt to assign to frob, I get the same error. I took a look at the gem source on github, and the setter frob= is set within the Flickr::Auth module, so I'm clueless as to where the error is. The API calls work successfully and the flickr object is initialized fine.

问题是来自gemcutter或github的flickr-fu gem版本为0.1.4，并且frob setter方法直到后续版本才实现。相反，从 github 安装 gem commonthread-flickr_fu v0.3.0，并且 frob 是可写的。
The issue is that the flickr-fu gem from gemcutter or github is at version 0.1.4, and the frob setter method wasn't implemented until subsequent version. Instead install the gem commonthread-flickr_fu v0.3.0 from github, and the frob is writeable.
