Rails：Rake在提及另一个模型类时会出现Zeitwerk错误

发布于 2025-02-06 19:18:34 字数 9972 浏览 2 评论 0原文

因此，我有一个非常奇怪的铁轨问题（6.1.4）。一切都在正常操作中运行良好，但是当我尝试从耙子任务中使用我的某些模型（例如Seeds.rb中的代码），我会收到以下错误：typeerror：typeerror：superClass不匹配类别的类评论

之后进行一堆挖掘，我将罪魁祸首缩小到了一个事实，即在我的一个模型类中，我会引用另一个名称。具体而言，以下代码足以创建问题，

class Question < ApplicationRecord
  include JsonHelpers
  include PostableHelpers

  puts "#{Comment.inspect}"
end

请注意，当我评论注释类的整个正文时，仍然会发生错误，因此这只是

class Comment < ApplicationRecord
end

注释是另一个模型（在Models/comment.rb中。如果我删除有关评论的参考，则没有问题（但是任何此类参考会引起问题），当我简单地响应Web请求时，也没有问题。 （在我的真实代码中，我有一个类宏，该宏可创建一个多态性属于_TO，并占用允许的相关类来定义某些实用方法和验证）。

感觉就像是加载常数的某种问题，但我不知道该如何修复它。即使是在正确方向上的简单指针也会非常有帮助。

我在下面包含了整个错误以进行完整。如果有帮助，我很乐意添加更多代码，但是仅仅发布了整个应用程序，我不确定什么是相关的。

So I'm having a really weird rails problem (6.1.4). Everything runs fine in normal operation but when I try to use some of my models from inside a rake task (e.g. code in seeds.rb) I get the following error: TypeError: superclass mismatch for class Comment

After doing a bunch of digging, I've narrowed the culprit down to the fact that inside one of my model classes I reference the name of another. Specifically, the following code suffices to create the problem

class Question < ApplicationRecord
  include JsonHelpers
  include PostableHelpers

  puts "#{Comment.inspect}"
end

Note that the error still happens when I comment out the whole body of the Comment class so it is just

class Comment < ApplicationRecord
end

Where Comment is another model (in models/comment.rb inheriting from ApplicationRecord). If I delete the reference to Comment in Question there is no problem (but any such reference causes the issue), nor is there a problem when I simply respond to web requests. (In my real code I have a class macro which creates a polymorphic belongs_to and takes the allowed related classes to define some utility methods and validation).

It feels like it's some kind of problem with loading constants but I have no idea how to go about fixing it. Even a simple pointer in the right direction would be super helpful.

I've included the whole error below for completeness. I'm happy to add more code if it helps, but short of just posting the whole application I'm not sure what would be relevant.

好的，感谢Xavier Noria的惊人帮助，我终于对其进行了追踪。如果有人遇到问题，我将在此处包含答案。

最终，问题是我执行了一个耙式任务，该任务定义为如下：

require 'rexml/document'
include REXML

namespace :db do
  desc "Delete all unconfirmed users after 1 day"
  task :import_journal_abbrevs => :environment do

  ...

end

不幸的是，Rexml定义了一个名为“评论”的类，该级别与我的同名模型类相抵触。作为此答案警告将包含放置在顶级污染对象名称空间。相反，我应该写

require 'rexml/document'

namespace :db do
  desc "Delete all unconfirmed users after 1 day"
  task :import_journal_abbrevs => :environment do
  include REXML
  ...
end

Ok, thanks to the amazing help by Xavier Noria I finally tracked it down. I'll include the answer here in case anyone else runs into the problem.

Ultimately, the issues was that I had a rake task that was defined as follows:

require 'rexml/document'
include REXML

namespace :db do
  desc "Delete all unconfirmed users after 1 day"
  task :import_journal_abbrevs => :environment do

  ...

end

Unfortunately, REXML defines a class named Comment which was conflicting with my model class of the same name. As this answer warns placing the include at the top level pollutes the Object namespace. Instead, I should have written

require 'rexml/document'

namespace :db do
  desc "Delete all unconfirmed users after 1 day"
  task :import_journal_abbrevs => :environment do
  include REXML
  ...
end
