我今晚在部署时遇到了一些问题,我正试图尽快解决这个问题

我不知道为什么会这样。在本地一切正常,但在heroku上却不行。在研究之后,我尝试了各种不同的修复方法,但我可能不得不完全重命名这个类 CommentsController(希望这有效)。最好的方法是什么?我对 Rails 很陌生,所以我需要一些帮助来正确更改这些内容。

这是 CommentsController 的样子,仅供参考:

class CommentsController < ApplicationController
  def new
    @post = Post.new(params[:post])
  end

  def show
    @comment = Comment.find(params[:id])
    respond_to do |format|
      format.js
    end
  end

  def create
    @post = Post.find(params[:post_id])
    @comment = Comment.new(params[:comment])
    @comment.micropost = @post
    @comment.user = current_user
    if @comment.save
      redirect_to(:back)
    else
      render partial: 'shared/_comment_form', locals: { post: @post }
    end
  end
end

评论与每个帖子相关联(用户可以对帖子发表评论)。如果需要,我也会发布其他代码。

这是heroku日志中的错误

路由.db

SampleApp::Application.routes.draw do
  resources :posts, :path => "posts"

  resources :users do
    resources :messages do
      collection do
        post :delete_selected
      end
    end
  end

  ActiveAdmin.routes(self)

  devise_for :admin_users, ActiveAdmin::Devise.config

  resources :users do
    member do
      get :following, :followers
    end
  end

  resources :sessions, only: [:new, :create, :destroy]
  resources :posts, only: [:create, :destroy]
  resources :relationships, only: [:create, :destroy]
  resources :posts do
    resources :comments
  end

  root to: 'static_pages#home'

  match '/signup',   to: 'users#new'
  match '/signin',   to: 'sessions#new'
  match '/signout',  to: 'sessions#destroy', via: :delete

  match '/post',    to: 'static_pages#post'
  match '/post1',   to: 'static_pages#post1'
  match '/faq',     to: 'static_pages#faq'
  match '/review',  to: 'users#review'
  match "/posts/:id/review" => "posts#review"
end

当我在 rails app 文件夹中运行高级索引搜索时,出现了以下相关文件

- comments_controller.rb
- comments_helper.rb
- comments_helper_spec.rb
- comments_controller_spec.rb
- 3 migration files
- routes.rb (posted above)
- schema.rb (table called "active_admin_comments" and table called "comments')
- post.rb model (has_many :comments)
- user.rb model (has_many :comments)
- comment.rb model
- active_admin.rb in config/initializer (any instance where I find "comments" has been #'ed out")

我遇到了几乎相同的问题(服务器正确启动,但 RSpec 失败并出现同样的错误)。就我而言,问题出在 ActiveAdmin (0.6.0) 中。不知道到底是什么,也许与命名空间有关。

刚刚降级到 0.5.0 在那个版本上,我对 CommentsController 没有任何问题。

我与管理命名空间有类似的冲突,因为我Admin::CommentsController在我的应用程序中定义了一个。

尝试将 ActiveAdmin 的默认命名空间更改为“admin”以外的名称

配置/初始化程序/active_admin.rb

config.default_namespace = :activeadmin # Default :admin

我假设 ActiveAdmin 有自己的 CommentsController 来自另一个基类。它只影响运行测试,所以我只是将路线更改为:

unless Rails.env.test?
  devise_for :admin_users, ActiveAdmin::Devise.config
  ActiveAdmin.routes(self)
end

除非您想针对 ActiveAdmin 中的路由进行测试,否则此解决方案效果很好。

从 Active Admin 0.6.1 开始,您可以重命名 Active Admin 包含的评论模块,使其不会与您自己的冲突。这些是选项:

# == Admin Comments
#
# This allows your users to comment on any resource registered with Active Admin.
#
# You can completely disable comments:
# config.allow_comments = false
#
# You can disable the menu item for the comments index page:
# config.show_comments_in_menu = false
#
# You can change the name under which comments are registered:
# config.comments_registration_name = 'AdminComment'
