带有Vue的Rails 5.2 API不显示数据

Question

我有一个仅使用Rails API的应用程序，该应用程序可以在Story模型上执行基本的功能。 Vue模板应该使用API​​。这段时间运行良好，但突然似乎停止了。

在Postman中检查API，CRUD功能正在按预期运行。但是，Vue组件出现故障。例如。索引视图会呈现但不显示任何数据，即使“网络”标签显示的响应为200，也包含适当的数据。见下文：

以下是相关的前端文件：

List.vue：

<template>
  <div class="stories">
    <h1>Stories</h1>
    <div v-if="stories" class="table-wrap">
      <div>
        <router-link v-bind:to="{ name: 'NewStory' }" class="">Add Story</router-link>
      </div>
      <div v-for="story in stories" :key="story.id">
        <p>Title: {{story.id}}</p>
        <p>Overview: {{story.attributes.description}}</p>
        <button @click="deleteStory(story.id)">Delete {{story.attributes.title}} </button>
      </div>
    </div>
    <div v-else>
       There are no stories.. Let's add one now <br><br>
       <!-- <router-link v-bind:to="{ name: 'NewStory' }" class="add_story_link">Add Story</router-link> -->
    </div>
  </div>
</template>

<script>
import StoriesService from '@/services/StoriesService'
export default {
  name: 'stories',
  data () {
    return {
      stories: []
    }
  },
  mounted () {
    this.getStories()
  },
  methods: {
    async getStories () {
      const response = await StoriesService.fetchStories()
      this.stories = response.data.data
      console.log(this.stories)
    },
    async deleteStory (id) {
      await StoriesService.deleteStory(id)
      this.$router.push({ name: 'Stories' })
    }
  }
}

</script>

App.vue：

<template>
  <div id="app">
    <router-view/>
  </div>
</template>

<script>
export default {
  name: 'App'
}
</script>

<style>
#app {
  font-family: 'Avenir', Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
  color: #2c3e50;
  margin-top: 60px;
}
</style>

StoriesService.js：

import Api from '@/services/Api'

export default {
  fetchStories () {
    return Api().get('stories')
  },

  addStory (params) {
    return Api().post('stories', params)
  },

  getStory (params) {
    return Api().get(`/stories/${params.id}/`)
  },

  updateStory (params) {
    return Api().put(`/stories/${params.id}/`, params)
  },

  deleteStory (id) {
    return Api().delete(`stories/` + id)
  }
}

Api.js：

import axios from 'axios'

export default() => {
  return axios.create({
    baseURL: `http://localhost:3000/v1`
  })
}

main.js：

import Vue from 'vue'
import App from './App'
import router from './router'
import VueAxios from 'vue-axios'
import { securedAxiosInstance, plainAxiosInstance } from './backend/axios'

Vue.config.productionTip = false
Vue.use(VueAxios, {
  secured: securedAxiosInstance,
  plain: plainAxiosInstance
})

/* eslint-disable no-new */
new Vue({
  el: '#app',
  router,
  securedAxiosInstance,
  plainAxiosInstance,
  components: { App },
  template: '<App/>'
})
