过度提交 RailsS​​chemaUpToDate 在 --run 时通过，但在提交时失败

我遇到了一个奇怪的问题overcommit and Rails 5.0.2应用程序与ruby 2.4.0 :

$ overcommit --run
Running pre-commit hooks
Check if database schema is up to date..........[RailsSchemaUpToDate] OK
Check YAML syntax........................................[YamlSyntax] OK
Check Gemfile dependencies..............................[BundleCheck] OK
Check for vulnerable versions of gems...................[BundleAudit] OK
Analyze with RuboCop........................................[RuboCop] OK
Analyze with haml-lint.....................................[HamlLint] OK

✓ All pre-commit hooks passed
$ git ci -m "Overcommit and Linters added"
Running pre-commit hooks
Check if database schema is up to date..........[RailsSchemaUpToDate] FAILED
It looks like you're adding a migration, but did not update the schema file

✗ One or more pre-commit hooks failed

这是我的相关部分Gemfile:

group :lint do
  gem 'overcommit', '~> 0.41', require: false  # hook event pre-commit, pre-push
  gem 'brakeman', '~> 3.7.2', require: false  # A static analysis security vulnerability scanner
  gem 'haml-lint', '~> 0.26', require: false  # Syntax checker for HAML
  gem 'ruby_css_lint', '~> 0.1', require: false  # Syntax checker for CSS
  gem 'rubocop', '~> 0.50', require: false  # A Ruby static code analyzer
  gem 'bundler-audit', '~> 0.6'  # Check dependencies
end

In my .overcommit.yml I have:

PreCommit:
  ALL:
    exclude:
      - 'bin/**'
      - 'public/**'
      - 'vendor/**'
  # ...

  # Migration Check
  RailsSchemaUpToDate:
    enabled: true
    on_warn: fail

我的 db 文件夹结构是：

+-- db
| +-- seeds.rb
| +-- migrate
  | +-- 20170922082256_devise_create_users.rb
  | +-- 20170922084050_create_fans.rb
| +-- schema.rb

这是我的相关部分db/schema.rb:

ActiveRecord::Schema.define(version: 20170922084050) do
# ...
end

我尝试降级到ruby 2.3.1但我仍然遇到同样的问题。

有人遇到同样的问题吗？

我其实想通了。 看起来overcommit --run针对整个项目运行（除了未暂存提交的更改），而预提交挂钩仅在要提交的更改上触发。

我在该提交中添加了所有的短绒，我跑了bundle exec rubocop --auto-correct排除db/schema.rb in my .rubocop.yml对于所有警察。

这导致了存在migration_files（之前编辑的迁移文件）没有schema_files（没有进行任何更改schema.rb), so:

if migration_files.any? && schema_files.none?

发现引发了错误来源由布莱恩链接 https://github.com/brigade/overcommit/blob/master/lib/overcommit/hook/pre_commit/rails_schema_up_to_date.rb#L8.

因此，我刚刚承诺禁用过度使用，并且从下一次提交开始，此错误不再重现
