Question

我对redmine感到困扰。

当我使用Rest API（来自Microsoft Excel）创建新问题时，发生了内部错误500。从production.log看，发生了“NoMethodError”（见下面的消息）

Started POST "/redmine/issues.xml?key=XXXXXXX" for XX.XX.XX.XXX at 2016-05-30 14:44:10 +0900

所以，我尝试使用Web浏览器（IE11）创建新的issew。票证是正常创建的。这是production.log。

我已经尝试过迁移，清除缓存。我接下来该怎么做。

这是我在RHEL7.2上的环境

Environment:
  Redmine version                3.2.0.stable
  Ruby version                   2.2.4-p230 (2015-12-16) [x86_64-linux]
  Rails version                  4.2.5
  Environment                    production
  Database adapter               Mysql2
SCM:
  Subversion                     1.7.14
  Git                            1.8.3.1
  Filesystem                     
Redmine plugins:
  redmine_export_with_journals   0.0.8
  redmine_importer               1.2.2
  redmine_local_avatars          1.0.0
  redmine_xlsx_format_issue_exporter 0.1.2
  sidebar_hide                   0.0.7

这是assinable_versions源代码

# Versions that the issue can be assigned to
def assignable_versions
  return @assignable_versions if @assignable_versions

  versions = project.shared_versions.open.to_a #Here is line823

  if fixed_version
    if fixed_version_id_changed?
      # nothing to do
    elsif project_id_changed?
      if project.shared_versions.include?(fixed_version)
        versions << fixed_version
      end
    else
      versions << fixed_version
    end
  end
  @assignable_versions = versions.uniq.sort
end

Answer 1

发生错误是因为project为nil并且您正在尝试调用nil.shared_versions。所以改变if条件：

if !project.shared_versions.nil? 
  versions = project.shared_versions.open.to_a 
end

如下：

versions = project.shared_versions.open.to_a unless project.nil?

这将解决'未定义的方法'错误。

Answer 2

我已经解决了问题。 REST过程有一些不同。

至少redmine 2.4.4，我可以同时使用project_id = identifier和project_id = project_id进行创建。

但是，redmine 3.x，我只能使用project_id = project_id进行问题创建。

我无法通过REST API创建新问题
