Question

我有一个包含名为typename的varchar字段的简单表。它的定义如下：

CREATE TABLE public.ref_community_types
(
  id integer NOT NULL DEFAULT nextval('ref_community_types_id_seq'::regclass),
  typename character varying,
  created_at timestamp without time zone NOT NULL,
  updated_at timestamp without time zone NOT NULL,
  CONSTRAINT ref_community_types_pkey PRIMARY KEY (id)
)

我想通过我的REST API对该表中的所有行运行一个简单的GET，但是我收到了这500个错误：

  RefCommunityType Load (2.5ms)  SELECT "ref_community_types".* FROM "ref_community_types"
  Rendered ref_community_types/_ref_community_type.json.jbuilder (48.6ms)
  Rendered ref_community_types/index.json.jbuilder (68.2ms)
Completed 500 Internal Server Error in 204ms (ActiveRecord: 5.0ms)

ActionView::Template::Error (undefined method `type' for #<RefCommunityType:0x00000007068270>):
    1: json.extract! ref_community_type, :id, :type, :created_at, :updated_at
    2: json.url ref_community_type_url(ref_community_type, format: :json)

app/views/ref_community_types/index.json.jbuilder:1:in `_app_views_ref_community_types_index_json_jbuilder__546876462_59109520'

我的浏览器返回以下内容：

Request URL:http://localhost:3000/ref_community_types
Request Method:GET
Status Code:500 Internal Server Error

我查看了可能导致此问题的所有典型位置（routes.rb，models/ref_community_type.rb，controllers/ref_community_types_controller.rb，migrate/[date]_create_ref_community_types.rb），但它们都包含名称{{1 }}

我还能在哪儿看？我正在对“类型”一词进行搜索，但它非常通用，我的搜索结果会返回很多不相关的结果。

在app/views/ref_community_types/_ref_community_type.json.jbuilder中，将type更改为typename

REST API返回模型未定义方法错误
