活动资源后缀
原标题:ActiveResource Suffix

使用ActiveResource,对MyObject.find(id)的调用将获得“[self.site]/[self.prefix]/:id.[self.format]”。但是,我们正在访问的API的配置略有不同。我们需要访问“[self.site]/:id/[self.suffix].[self.format]”,而不是id.file_type。

即:获取http://api_path/:id/tool.json

有没有办法为这种情况配置活动资源?我在文件中找不到什么。

最佳回答

ActiveResource::Base.element_path是创建路径的方法:

def element_path(id, prefix_options = {}, query_options = nil)
  prefix_options, query_options = split_options(prefix_options) if query_options.nil?
  "#{prefix(prefix_options)}#{collection_name}/#{URI.escape id.to_s}.#{format.extension}#{query_string(query_options)}"
end

我会创建一个类来重新定义element_path,如下所示:

class CustomApiPath < ActiveResource::Base
  def element_path(id, prefix_options = {}, query_options = nil)
    prefix_options, query_options = split_options(prefix_options) if query_options.nil?
    "#{prefix(prefix_options)}#{URI.escape id.to_s}/#{collection_name}.#{format.extension}#{query_string(query_options)}"
  end
end

(警告:未测试),然后其他ActiveResource模型将继承自CustomApiPath,而不是ActiveResource::Base。
