Javascript Vue js2 vuex更新表格v-model值

我已经安装了vuex，我想稍后获取数据并更新表单模型，但失败了

在我的vuex中

  //state
  const state = {
   profile: [],
  }

  //getter
  const getters = {
   profileDetails: state => state.profile,
  }

 //the actions
 const actions = {
    getProfileDetails ({ commit }) {
        axios.get('/my-profile-details')
             .then((response) => {
               let data = response.data;
               commit(types.RECEIVED_USERS, {data});
              },
             );
     }
  }



 const mutations = {
  [types.RECEIVED_USERS] (state, { data }) {
    state.profile = data;
   state.dataloaded = true;
  },

}

现在在我的vue js文件中

export default{

    data: () => ({
       profile_form:{
           nickname:'',
           first_name:'',
           last_name:'',
           email:''
       }

    }),

    computed:{
        ...mapGetters({
            user: 'profileDetails',
        }),

    },

   methods:{
       setUpDetails(){
            this.profile_form.email = this.user.email; //the value is always undefined
        }
    },

    mounted(){
        this.$store.dispatch('getProfileDetails').then(
            (res)=>{
                console.log(res); //this is undefined
             this.setUpDetails(); ///this is never executed
            }
        );
        this.setUpDetails(); //tried adding it here
    }

通过使用vue developer工具进行检查，我可以看到vuex中有数据，但我的组件在操作中调用dispatch以获取数据后无法在vuex中获取数据

我哪里做错了

注意：我正在使用这些数据更新这样的表单

<input  v-model="profile_form.email" >

您装载的方法需要从

getProfileDetails

返回（res），但操作没有返回任何内容，因此您可以简单地尝试

 const actions = {
    getProfileDetails ({ commit }) {
      return axios.get('/my-profile-details')
        .then((response) => {
          let data = response.data;
          commit(types.RECEIVED_USERS, {data});
          return data // put value into promise
        },
      );
    }
  }

但是，更常见的做法是从操作（您正在执行的操作）中提交存储，并让组件从getter（您拥有的）中获取新值，即单向数据流

我就是这样安排的

data: () => ({
  profile_form:{
    nickname:'',
    first_name:'',
    last_name:'',
    email:''
  }
}),

mounted(){
  this.$store.dispatch('getProfileDetails')
}

computed: {
  ...mapGetters({
    user: 'profileDetails',
  }),
}

watch: {
  user (profileData){
    this.profile_form = Object.assign({}, profileData);
    }
},

methods:{
  submit(){
    this.$store.commit('submituser', this.profile_form)
  }
},
