bootstrap-vue表未填充我的数据库数据

Question

我想用数据库中的数据填充我的boots-vue表。我正在使用vuex尝试实现这一目标；但是，出于某种原因，bootstrap-vue表未获取数据。我检查了Vuex开发工具：

我在组件中添加了console.log('Getters: ' + this.$store.getters.allEmployees);，以查看将检索的内容，并且仅将Getters：输出到控制台。

为了进一步解决这个问题，我将[{"id":1,"name":"Jane Smith","email":"[email protected]","job_title":"Lead"},{"id":2,"name":"John Smith","email":"[email protected]","job_title":"Installer"}]硬编码为employees状态，现在将数据加载到表中。

Vuex模块employees.js

const state = {
    employees: [],
    employeesStatus: null,
};

const getters = {
    allEmployees: state => {
       return state.employees;
    },
};

const actions = {
    fetchAllEmployees({commit, state}) {
        commit('SET_EMPLOYEES_STATUS', 'loading');

        axios.get('/api/employees')
            .then(res => {
                commit('SET_EMPLOYEES', res.data);
                //console.log(state.employees);
                commit('SET_EMPLOYEES_STATUS', 'success');
            })
            .catch(error => {
                commit('SET_EMPLOYEES_STATUS', 'error');
            });
    },
};

const mutations = {
    SET_EMPLOYEES(state, employees) {
        state.employees = employees;
    },
    SET_EMPLOYEES_STATUS(state, status) {
        state.employeesStatus = status;
    } 
};

export default {
    state, getters, actions, mutations,
};

VueJS组件EmployeeDataTable.vue：

<template>
    <div class="overflow-auto pb-3" style="background: white; ">
        <b-card
        header="Employees"
        header-tag="header"
        >
            <b-pagination
            v-model="currentPage"
            :total-rows="rows"
            :per-page="perPage"
            aria-controls="my-table"
            ></b-pagination>

            <p class="mt-3">Current Page: {{ currentPage }}</p>

            <b-table
            id="employee-table"
            ref="employee-table"
            :items="items"
            :per-page="perPage"
            :current-page="currentPage"
            small
            ></b-table>
        </b-card>
    </div>
</template>

<script>
import { mapGetters } from 'vuex';

  export default {
    name: "EmployeeDataTable",

    data() {
      return {
        perPage: 3,
        currentPage: 1,
        items: [],
      }
    },
    computed: {
      ...mapGetters(['allEmployees']),

      rows() {
        return this.items.length
      }
    },
    methods: {
        getEmployees() {
          this.$store.dispatch('fetchAllEmployees').then(() => {
            this.items = this.$store.getters.allEmployees;
            console.log('Getters: ' + this.$store.getters.allEmployees); //<-Returns Getters:
          });
          //this.items = this.$store.getters.allEmployees;
        }
    },
    mounted() {
        this.getEmployees();
    }
  }
</script>

Answer 1

Phil的解释达到了目的。我更改的代码段是：

const actions = {
    fetchAllEmployees({commit, state}) {
        commit('SET_EMPLOYEES_STATUS', 'loading');

       return axios.get('/api/employees')
            .then(res => {
                commit('SET_EMPLOYEES', res.data);
                //console.log(state.employees);
                commit('SET_EMPLOYEES_STATUS', 'success');
            })
            .catch(error => {
                commit('SET_EMPLOYEES_STATUS', 'error');
            });
    },
};

和

    <b-table
    id="employee-table"
    ref="employee-table"
    :items="allEmployees"
    :per-page="perPage"
    :current-page="currentPage"
    small
    ></b-table>
