我在我的profie.html中有这样一行代码，它应该使用vue.js v-for和{{ val.division_name }}来显示除法运算的值。相反，这段代码返回的除法运算值是空白的，但我可以告诉你除法运算正在渲染的值，它只是空白值。

<select name="division_id" class="form-control form-select" id="division-id" aria-label="Default select example" v-model="formData.division_id" @change="onDivisionChange" required>
              <option value="0">Select Division</option>
              <option v-for="val in divisionListVue" :value="val.id">{{ val.division_name }}</option>
             </select>

这是console.log(data)返回的数据格式

的
这是console.log(this.divisionListVue);返回的数据格式

是什么原因导致vue显示空值？我已经有了vue使用这个脚本<script src="{% static 'js/vue.global.js' %}"></script>工作所需的静态文件。
