Ruby on rails 外键有问题的Rails引擎
我正在开发一个rails引擎,这是我的Ruby on rails 外键有问题的Rails引擎,ruby-on-rails,rspec,foreign-keys,rails-migrations,rails-engines,Ruby On Rails,Rspec,Foreign Keys,Rails Migrations,Rails Engines,我正在开发一个rails引擎,这是我的gem.gempec s.required_ruby_version = '~> 2.2' s.add_dependency 'rails', '>= 4.2.1' s.add_dependency 'enumerate_it' s.add_dependency 'slim-rails' s.add_dependency 'bootstrap-sass' s.add_dependency 'jquery-rails' s.add_develo

这是我的迁移文件,当我运行install命令时,它将复制到我的rails应用程序:

我省略了引擎的路径,因为它是私有的
好的,这就是我的问题,当我运行我的迁移RAILS\u ENV=test rake db:drop db:create db:migrate
然后运行我的specsrspec
时,我的配置都很好
但是当我尝试在gem.gempec
和Gemfile
中更新rails4.2.1
引擎时,如下所示:
gem.gemspec
s.required_ruby_version = '~> 2.2'
s.add_dependency 'rails', '>= 4.2.1'
s.add_dependency 'enumerate_it'
s.add_dependency 'slim-rails'
s.add_dependency 'bootstrap-sass'
s.add_dependency 'jquery-rails'
s.add_development_dependency 'rdoc'
s.add_development_dependency 'tomdoc'
s.add_development_dependency 'sqlite3'
s.add_development_dependency 'rspec-rails'
s.add_development_dependency 'timecop'
s.add_development_dependency 'shoulda-matchers'
s.add_development_dependency 'factory_girl_rails'
s.add_development_dependency 'database_cleaner'
s.add_development_dependency 'awesome_print'
s.add_development_dependency 'guard'
s.add_development_dependency 'guard-rspec'
s.add_development_dependency 'guard-migrate'
s.add_development_dependency 'guard-livereload'
s.add_development_dependency 'thor'
s.add_development_dependency 'simplecov'
s.add_development_dependency 'codeclimate-test-reporter'
使用我的引擎的my rails应用程序的Gemfile
gem'rails','4.2.1'
然后我为我的引擎和rails应用程序运行bundle update
当我运行RAILS\u ENV=test rake db:drop db:create db:migrate
时,迁移工作正常,但当我尝试运行rspec
时,我遇到了与外键相关的错误,如下所示:
==20150416144229 CreateMpaStorySchema:正在迁移=============================
--创建表格(:mpa\U故事\U原型)
->0.2872s
--创建表格(:mpa_故事_邻接矩阵)
雷克流产了!
StandardError:发生错误,此迁移和所有后续迁移已取消:
PG::UndefinedTable: ERRO: relação "archetypes" não existe :
ALTER TABLE "mpa_story_adjacency_matrices" ADD CONSTRAINT "fk_rails_2b6894b4f9"
FOREIGN KEY ("archetype_id")
REFERENCES "archetypes" ("id")
有人知道rails 4.2.1和引擎是否存在一些bug吗 这是因为您的迁移正在生成一个前缀表:mpa\u story\u原型 两种可能的解决办法: 1-使用references方法时,显式声明表的
t.references :mpa_story_archetype, index: true, foreign_key: true
2-自行添加外键,删除t.references上的外键选项,并调用Add\u-foreign\u-key方法:
add_foreign_key :mpa_story_adjacency_matrices, :mpa_story_archetypes, column: :archetype_id
我更喜欢解决方案2,并且您必须在每个具有外键的表中执行此操作您是否确认原型表已经存在?
add_foreign_key :mpa_story_adjacency_matrices, :mpa_story_archetypes, column: :archetype_id
