生成迁移时Rails错误的参数数量错误

Question

我正在尝试运行bin/rails generate migration ClientsUsersXrefTable

我得到这个错误：

/Users/user/.rbenv/versions/2.7.3/lib/ruby/gems/2.7.0/gems/activerecord-5.2.6/lib/active_record/
persistence.rb:138:in `destroy': wrong number of arguments (given 0, expected 1) (ArgumentError)

我在 ruby​​ 2.7.3p183 和 rails 5.2.6 上。我错过了什么？这是完整的跟踪。

Answer 1

每当您运行 Rails 命令时，它可能会在执行实际工作之前设置一堆类，并且与许多其他语言不同，在 Ruby 中，此设置由实际的 Ruby 代码完成（这就是 DSL 的工作方式），并且在此期间运行的任何损坏的代码都会阻止任何命令运行。

它不会运行任何实例方法，但任何损坏的类级代码都会导致问题。

所以迁移的事情只是一个红鲱鱼，大概你所有的 Rails 命令都坏了。

根据您的堆栈跟踪，app/models/user.rb:8（您尚未提供）正在初始化期间运行。在初始化期间加载模型很常见，但在这种情况下，代码会被破坏。

查看 ActiveRecord 源代码（使用 less -N `bundle show activerecord`/lib/active_record/persistence.rb 并查看第 138 行），您似乎正在调用 destroy 类方法（例如 User.destroy(1)）但没有参数，就像您使用 destroy 实例方法一样（例如User.find(1).destroy)。所以你应该确保你了解这两者之间的区别。

我不确定您为什么要在实例方法之外调用User.destroy，但没有相关的用户模型代码，我不能说。那里只有一个流浪的“毁灭”吗？
