小编use*_*341的帖子

如果我遗漏了任何东西,请告诉我.我无法弄清楚为什么我的views/references /文件夹无法访问.既不可用new.html.erb也不index.html.erb可用.当我转到localhost:3000/references我的错误是:

RuntimeError in ReferencesController#index
Circular dependency detected while autoloading constant ReferencesController

我相信这是设置,它不应该是一个Rails问题,因为我的其他控制器工作正常.

我的路线文件中有resources :references我的rake路线产生:

references GET    /references(.:format)          references#index
           POST   /references(.:format)          references#create
new_reference GET    /references/new(.:format)      references#new
edit_reference GET    /references/:id/edit(.:format) references#edit
reference GET    /references/:id(.:format)      references#show
           PATCH  /references/:id(.:format)      references#update
           PUT    /references/:id(.:format)      references#update
           DELETE /references/:id(.:format)      references#destroy

所以我试着通过这个到达我的索引页面,这应该是正确的路径.

<%= link_to 'References', references_path, class: 'navbar-brand' %>

我的模特:

class Reference < ActiveRecord::Base
  belongs_to :user
end

我的控制器:

class ReferencesControllers < ApplicationController
  def index
    @references = Reference.all
  end

谷歌搜索后,似乎每个类似的问题都是从Rails 3升级到Rails …

我可以使用postgres.app在Mac上使用postgres.app在应用内部输入rails而没有任何问题,但是,当我转到localhost:3000时,它给了我这个错误:

PG::ConnectionBad
FATAL: role "myapp" does not exist

我一开始认为问题是database.yml文件,但是heroku docs甚至说它的方式是这样的:https://devcenter.heroku.com/articles/getting-started-with-rails4

development:
adapter: postgresql
encoding: unicode
database: myapp_development
pool: 5
username: myapp
password:

这是我的完整日志.我见过类似的问题,但他们只是模糊地与此有关.
