使用jbuilder的react-rails不起作用

标签: ruby-on-rails reactjs jbuilder react-rails

我尝试将react-rails与jbuilder一起使用。 例如,我使用this great sample app of react-rails并尝试重写以使用jbuilder作为json响应,使用react-railsthis part的引用。

这些是主要的重写部分:

# app/views/comments/index.html.erb
<%= react_component 'CommentBox', render(template: 'comments/index.json.jbuilder'), {prerender: true} %>
# app/views/comments/index.json.jbuilder
json.presenter do
  json.comments(@comments) do |comment|
    json.extract! comment, :id, :author
  end
  json.form do
    json.action comments_path
    json.csrf_param request_forgery_protection_token
    json.csrf_token form_authenticity_token
  end
end
json.imgSrc image_path("gundam.jpg")

但是我收到了以下错误:

Started GET "/comments" for 127.0.0.1 at 2015-04-07 18:26:40 +0900
Processing by CommentsController#index as HTML
  Comment Load (0.9ms)  SELECT  "comments".* FROM "comments"   ORDER BY "comments"."id" DESC LIMIT 5

你有任何想法解决这个错误吗? 提前谢谢。

看起来引发了意外的令牌,因为当this.props.presenter已经是JSON对象时,CommentBox组件正在调用JSON.parse() in getInitialState

您可以通过移除JSON.parse()中的getInitialState并仅返回this.props.presenter来修复此问题。

这是解析现有JSON对象的相关answer
