Vue-将v模型与vuex一起使用

Question

我正在构建搜索页面，并且难以在vuex商店中使用v-model更新我的计算属性。我正在使用基于Vue构建的this wordpress theme

在我的数据中，我有一个主要的帖子请求，该请求从wordpress rest api提取数据，并提供3个参数，这些参数我希望能够使用v-model进行设置并相应地获取帖子。

postsRequest: {
  type: 'quote',
  params: {
    per_page: 50,
    search: null,
    authors: null,
    tags: null
 },
 showLoading: true
},

然后，我要获取作者和标签的列表，以便能够获取需要在postsRequest参数中使用的ID。

authorsRequest: {
   type: 'authors',
   params: {
     cq_per_page: 500,
   },
},
topicsRequest: {
  type: 'tags',
  params: {
    per_page: 100,
  },
},

下面是我计算的属性和方法

computed: {
        authors () {
            return this.$store.getters.requestedItems(this.authorsRequest)
        },
        topics () {
            return this.$store.getters.requestedItems(this.topicsRequest)
        },
        posts() {
            return this.$store.getters.requestedItems(this.postsRequest)
        }
    },
    methods: {
        getAuthors() {
            return this.$store.dispatch('getItems', this.authorsRequest)
        },
        getTopics() {
            return this.$store.dispatch('getItems', this.topicsRequest)
        },
        getPosts() {
            return this.$store.dispatch('getItems', this.postsRequest)
        },
    },
    created() {
        this.getAuthors()
        this.getTopics()
        this.getPosts()
    },

我尝试在所有三个v模型属性上设置手表。在vue开发人员工具中查看，该手表确实更改了v模型更改中的postsRequest.params，但帖子保持不变。

watch: {
        "searchAuthor": function() {
            this.postsRequest.params.search = null
            this.postsRequest.params.authors = this.searchAuthor
            this.postsRequest.params.tags = null
            this.getPosts()
        },
        "searchTopic": function() {
            this.postsRequest.params.search = null
            this.postsRequest.params.authors = null
            this.postsRequest.params.tags = this.searchTopic
            this.getPosts()
        },
        "searchTerm": function() {
            this.postsRequest.params.search = this.searchTerm
            this.postsRequest.params.authors = null
            this.postsRequest.params.tags = null
            this.getPosts()
        }
    },

模板

<div class="advanced-search">
    <input type="text" 
       name="searchTerm"
       placeholder="Search title..." 
       tabindex="1"
       v-model="searchTerm">
    <select v-model="searchAuthor">
       <option value="">All</option>
       <option 
          v-for="author in authors"
          :value="author.id"
          :key="author.id">{{ author.name }}</option>
    </select>
    <select v-model="searchTopic">
       <option value="">All</option>
       <option 
          v-for="topic in topics"
          :value="topic.id"
          :key="topic.id">{{ topic.name }}</option>
    </select>
</div>

<section v-if="posts">
   <post-item
      v-for="post in posts"
      :key="post.id"
      :post="post"
      :postmeta=false
   />
</section>

我正在学习中，任何帮助都将受到高度赞赏。
