Question

我有一条看起来像这样的路线：

resources :property_searches, :path => 'search'

这将产生以下路线：

 property_searches GET    /search(.:format)                                                             property_searches#index
                   POST   /search(.:format)                                                             property_searches#create
new_property_search GET    /search/new(.:format)                                                         property_searches#new
edit_property_search GET    /search/:id/edit(.:format)                                                    property_searches#edit
    property_search GET    /search/:id(.:format)                                                         property_searches#show
                    PUT    /search/:id(.:format)                                                         property_searches#update
                    DELETE /search/:id(.:format)                                                         property_searches#destroy

这就是我的PropertySearchesController#Index中的内容：

@properties = Property.first(5) #This is just a test

respond_to do |format|
  format.html {}

  format.json {}

  format.fullsearch do
    render :formats => [ :js ]
  end

  format.livesearch do

  end

  format.filtersearch do
    render :formats => [ :quicksearch ]
  end
end

然后在我的views/property_searches/index.json.jbuilder中，我有以下内容：

json.properties do
  json.array!(@properties) do |property|
    json.name property.name
  end
end

当我访问地址栏中的/search.json时，这就是我在日志中看到的内容：

我还尝试将其放在我的respond_to块中：

  format.json { render json: {properties: []} }

尽管它不会产生相同的错误，但是当我转到页面时，我实际上只是在页面上看到了这一点：

{"properties":[]}

它没有显示我设置的@properties中的值。

是什么原因造成的，我该如何解决？

当我直接渲染集合时，它可以工作，即当我这样做时：

format.json { render json: @properties }

但是，这并没有遍历它。它只是吐出值，日志看起来像这样：

Answer 1

愚蠢的我。我以为Rails会自动将jbuilder宝石添加到我的Gemfile中，但是事实证明，直到Rails 3.2才发生。我正在使用的这个应用程序是一个旧的Rails 3应用程序，已升级到3.2，因此jbuilder gem不在我的Gemfile中。

一旦我添加了它，它就像一个饰物。

为什么Rails找不到我的jbuilder模板或不呈现它？
