rails.vim

This is a massive (in a good way) Vim plugin for editing Ruby on Rails
applications.

• Easy navigation of the Rails directory structure. gf considers
  context and knows about partials, fixtures, and much more. There are
  two commands, :A (alternate) and :R (related) for easy jumping
  between files, including favorites like model to schema, template to
  helper, and controller to functional test. Commands like :Emodel,
  :Eview, :Econtroller, are provided to :edit files by type, along
  with S, V, and T variants for :split, :vsplit, and
  :tabedit. Throw a bang on the end (:Emodel foo!) to automatically
  create the file with the standard boilerplate if it doesn't exist.
  :help rails-navigation

• Enhanced syntax highlighting. From has_and_belongs_to_many to
  distance_of_time_in_words, it's here.

• Interface to the rails command. Generally, use :Rails console to
  call rails console. Many commands have wrappers with additional features:
  :Generate controller Blog generates a blog controller and loads the
  generated files into the quickfix list, and :Runner wraps rails runner
  and doubles as a direct test runner. :help rails-exec

• Default task runner. Use :Rails (with no arguments) to run the current
  test, spec, or feature. Use :.Rails to do a focused run of just the
  method, example, or scenario on the current line. :Rails can also run
  arbitrary migrations, load individual fixtures, and more.
  :help rails-default-task

• Partial and concern extraction. In a view, :Extract {file}
  replaces the desired range (typically selected in visual line mode)
  with render '{file}', which is automatically created with your
  content. In a model or controller, a concern is created, with the
  appropriate include declaration left behind.
  :help rails-:Extract

• Fully customizable. Define "projections" at the global, app, or gem
  level to define navigation commands and override the alternate file,
  default rake task, syntax highlighting, and more.
  :help rails-projections.

• Integration with other plugins. If [dispatch.vim][] is installed, :Rails
  and other command wrappers will use it for asynchronous execution. Users of
  dadbod.vim and
  dbext get easy access to
  their application's database. Users of
  abolish.vim get pluralize and
  tableize coercions, and users of [bundler.vim][] get a smattering of
  features. :help rails-integration

如果你要找一个文件

:Rfind routes.rb

如果你想打开一个model

:Rmodel user

如果你想打开一个conotroller

:Rcontroller users
:Rcont users

如果你想打开一个view

:Rview users/index
:Rview users/_user

如果你的当前窗口的文件是在app/views/users/下的话

:Rview show #相当于 :Rview users/show

如果你当前光标是controller的index方法中,直接按 R 可以中转到视图文件 index.html.erb中

其它的方法如

:Rserver #启动服务器
:Rserver! #停止服务器
:Rjavascript js_name #打开js文件

还有很多,输入帮助命令自己看吧
