application.rb paths.app.views未定义的方法‘`app’用于Rails::Paths::Root

Question

使用devise 2.1.0

我必须覆盖设备注册控制器。在这个过程中，我不得不移动我的devise views目录来与新的控制器相对应。我的config/applications.rb文件中有以下代码

    paths.app.views << "app/views/devise"

当我尝试使用rails s启动服务器时，它抛出了一个错误

    ...config/application.rb:65:in `<class:Application>': undefined method `app' for #<Rails::Paths::Root:0x00000103537740> (NoMethodError)

我是rails的新手。但是我知道在某个地方有一个根类并没有定义app。我得到了在堆栈中使用这个paths.app.views的建议。

这是完整的applications.rb

require File.expand_path('../boot', __FILE__)

require 'rails/all'

if defined?(Bundler)
  # If you precompile assets before deploying to production, use this line
  Bundler.require(*Rails.groups(:assets => %w(development test)))
  # If you want your assets lazily compiled in production, use this line
  # Bundler.require(:default, :assets, Rails.env)
end

module Growle
  class Application < Rails::Application
    # Settings in config/environments/* take precedence over those specified here.
    # Application configuration should go into files in config/initializers
    # -- all .rb files in that directory are automatically loaded.

    # Custom directories with classes and modules you want to be autoloadable.
    # config.autoload_paths += %W(#{config.root}/extras)

    # Only load the plugins named here, in the order given (default is alphabetical).
    # :all can be used as a placeholder for all plugins not explicitly named.
    # config.plugins = [ :exception_notification, :ssl_requirement, :all ]

    # Activate observers that should always be running.
    # config.active_record.observers = :cacher, :garbage_collector, :forum_observer

    # Set Time.zone default to the specified zone and make Active Record auto-convert to this zone.
    # Run "rake -D time" for a list of tasks for finding time zone names. Default is UTC.
    # config.time_zone = 'Central Time (US & Canada)'

    # The default locale is :en and all translations from config/locales/*.rb,yml are auto loaded.
    # config.i18n.load_path += Dir[Rails.root.join('my', 'locales', '*.{rb,yml}').to_s]
    # config.i18n.default_locale = :de

    # Configure the default encoding used in templates for Ruby 1.9.
    config.encoding = "utf-8"

    # Configure sensitive parameters which will be filtered from the log file.
    config.filter_parameters += [:password, :password_confirmation]

    #don't generate RSpec tests for views and helper
    config.generators do |g|
      g.view_specs false
      g.helper_specs false
    end

    # Use SQL instead of Active Record's schema dumper when creating the database.
    # This is necessary if your schema can't be completely dumped by the schema dumper,
    # like if you have constraints or database-specific column types
    # config.active_record.schema_format = :sql

    # Enforce whitelist mode for mass assignment.
    # This will create an empty whitelist of attributes available for mass-assignment for all models
    # in your app. As such, your models will need to explicitly whitelist or blacklist accessible
    # parameters by using an attr_accessible or attr_protected declaration.
    config.active_record.whitelist_attributes = true

    # Enable the asset pipeline
    config.assets.enabled = true

    # Version of your assets, change this if you want to expire all your assets
    config.assets.version = '1.0'

    paths.app.views << "app/views/devise"
  end
end

通过阅读你的最后一条评论，听起来你想要view_paths=或prepend_view_path。

这些可以在控制器中的类级别进行设置。

如果这不是您要查找的内容，请考虑阅读Override devise registrations controller获取信息。
