【问题描述】：
我正在学习 vuetify 框架，我设法使用了大部分组件，但我遇到了自动完成组件的问题。 从头开始使用它工作正常，如果我在创建过程中尝试设置值，它根本不起作用。 我尝试扩展其中一个 vuetify 示例，但没有成功。
我想在创建期间从 API 加载第一个值，但它保持为空。
感谢您的帮助。
new Vue({
el: '#app',
data: () => ({
descriptionLimit: 60,

model: null,
search: "Cats"
}),

search="Cats"
},
computed: {
fields () {
if (!this.model) return []
return Object.keys(this.model).map(key => {
return {
key: key,
value: this.model[key] || 'n/a'
}
})
},
items () {
return this.entries.map(entry => {
const Description = entry.Description.length > this.descriptionLimit
? entry.Description.slice(0, this.descriptionLimit) + '...'
: entry.Description
return Object.assign({}, entry, { Description })
})

// Items have already been loaded

this.isLoading = true
console.log("loadgin data")
