Ruby on rails Rails ActiveResource:：基本或Redmine错误？

我正试图通过RESTAPI使用Redmine，以保持和更新项目成员资格，如中所述

为此，我在以RoR编写的客户机应用程序中加入了以下“redmine_项目”模型：

class RedmineProject < ActiveResource::Base
  self.site ='http://localhost:3001'
  self.format = :json
  self.user = 'admin'
  self.password = 'admin'
  self.element_name = 'project'
  self.collection_name = 'projects'

end

Redmine正确地处理了文件的第一部分（事实上，如果我只是尝试RedmineProject.find（4）我的项目数据中确实有JSON），但是。。 我无法使用发布新成员身份

.post（：成员身份，：用户id=>12，：角色id=>4]）

以下是我的应用程序控制台的结果：

ActiveResource::ServerError: Failed.  Response code = 500.  Response message = Internal Server Error .
    from /home/marc/.rvm/gems/ruby-1.9.3-p448/gems/activeresource-3.2.13/lib/active_resource/connection.rb:148:in `handle_response'

这是redmine终端的结果：

我的代码有问题吗？还是（不太可能）有错误？

我假设您使用的是Redmine v2.3

查看引发错误的位置，我看到

成员

是空数组！ 查看构建

成员的过程

我可以假设

params[：membership]

为空，请查看您的日志：

{"project"=>{"created_on"=>"2013-10-23T00:58:15Z", "description"=>"azfazfazf zaf azffza", "homepage"=>"", "id"=>4, "identifier"=>"team-35", "name"=>"azfazf", "updated_on"=>"2013-10-23T00:58:15Z"}, "role_ids"=>["4"], "user_id"=>"12", "project_id"=>"4"}

尝试更改发送参数以将其包装为

成员身份

。 类似的内容在

我认为这应该行得通

.post(:memberships,:membership => {:user_id => 12, :role_ids => [4]})

您好，非常感谢您的帮助@gotva，唯一的一件事是我需要在param:membership（无S）中包含，因此我们有：

.post（：memberships，：memberships=>{:user\u id=>12，：role\u id=>[4]}）

非常感谢，没有您我无法做到：）

{
  "membership":
  {
    "user_id": 27,
    "role_ids": [ 2 ]
  }
}

.post(:memberships,:membership => {:user_id => 12, :role_ids => [4]})
