データテーブルにvuetifyを使用しています。検索フィルターを除き、ページネーションとソートは機能しています。検索フィルターからの応答データは正しいですが、問題はテンプレートへの応答をレンダリングしないことです。 vuetify docsには、ページネーションとソートのみがあります。サーバー側で検索機能を実装しようとしています。
My User.vue
export default{
data () {
return {
max25chars: (v) => v.length <= 25 || 'Input too long!',
tmp: '',
search: '',
totalItems: 0,
pagination: {
rowsPerPage: 1,
search: ''
},
headers: [
{
text: 'Name',
sortable: true,
value: 'name',
align: 'left'
},
{
text: 'Email Add',
sortable: true,
value:'email',
align: 'left'
},
{
text: 'Roles',
sortable: true,
value:'roles_permissions',
align: 'left'
},
{
text: 'Date joined',
sortable: true,
value:'created_at',
align: 'left'
}
],
items: [],
loading: false,
timer: null
}
},
watch:{
pagination:{
handler(){
this.getDataFromApi()
.then(data => {
const self = this;
self.items = data.items;
self.totalItems = data.total;
})
},
deep: true
}
},
mounted(){
this.getDataFromApi()
.then(data => {
this.items = data.items;
this.totalItems = data.total;
});
},
methods:{
getDataFromApi(search_val){
this.loading = true;
return new Promise((resolve, reject) => {
const { sortBy, descending, page, rowsPerPage } = this.pagination
const search = this.search;
//console.log(search);
clearTimeout(this.timer);
this.timer = setTimeout(function(){
axios({
url: '/prod/api/user_table',
method:'post',
data:{
sortBy : sortBy,
descending: descending,
page : page,
rowsPerPage : rowsPerPage,
search_val : search
}
})
.then(response=>{
if(response.status == 200){
let items = response.data.data;
const total = response.data.totalRecords;
this.loading = false;
resolve({
items,
total
});
}
})
.catch(error=>{
if(error.response){
console.log(error.response);
}
})
},1000);
})
},
fetchDataFromApi(value){
//console.log(value);
}
},
created(){
}
}
ここにlaravelを使用したバックエンド側があります
public function dataTable(Request $request){
//return Datatable::eloquent(User::query())->make(true);
$sortBy = $request->sortBy;
$descending = $request->descending;
$page = $request->page;
$rowsPerPage = $request->rowsPerPage;
$search_val = $request->search_val;
//echo $rowsPerPage;
if($descending){
$orderedBy = 'desc';
}else{
$orderedBy = 'asc';
}
$start = ($page - 1) * $rowsPerPage;
/*$totalRec = User::all();
if(empty(trim($search_val))){
$user = User::orderBy($sortBy,$orderedBy)->skip($start)->take($rowsPerPage)->get();
}else{
$user = User::where([
]);
}*/
$query = User::query();
$column = ['name', 'email'];
foreach ($column as $col) {
$query->orWhere($col, 'LIKE','%'.$search_val.'%');
}
$query->orderBy($sortBy,$orderedBy)->skip($start)->take($rowsPerPage);
$arr_items = [];
foreach ($query->get()->toArray() as $shit => $v) {
$arr_items['data'][] = array(
'value' => $v['id'],
'name' => $v['name'],
'email' => $v['email'],
'roles_permissions' => '',
'created_at' => $v['created_at']
);
}
$arr_items['totalRecords'] = User::count();
return response()->json($arr_items);
}
サーバー側が必要な場合searchandsortin vuetify .js datatable、vuejs部分にいくつかの変更を加える必要があります。
import {environment} from '../../environment';
export default {
name: "Category",
data() {
return {
categories: [],
search: '',
total: 0,
loading: false,
pagination: {},
headers: [
{text: 'ID', value: 'id'},
{text: 'Name', value: 'name'},
{text: 'Actions', value: 'name', sortable: false, align: 'center'}
],
rowsPerPageItems: [5, 10, 20, 50, 100],
}
},
watch: {
pagination {
this.getCategoriesByPagination();
},
search() {
this.getCategoriesByPagination();
}
},
methods: {
getCategoriesByPagination() {
this.loading = true;
// get by search keyword
if (this.search) {
axios.get(`${environment.apiUrl}/category-filter?query=${this.search}&page=${this.pagination.page}&per_page=${this.pagination.rowsPerPage}`)
.then(res => {
this.categories = res.data.data;
this.total = res.data.meta.total;
})
.catch(err => console.log(err.response.data))
.finally(() => this.loading = false);
}
// get by sort option
if (this.pagination.sortBy && !this.search) {
const direction = this.pagination.descending ? 'desc' : 'asc';
axios.get(`${environment.apiUrl}/category-order?direction=${direction}&sortBy=${this.pagination.sortBy}&page=${this.pagination.page}&per_page=${this.pagination.rowsPerPage}`)
.then(res => {
this.loading = false;
this.categories = res.data.data;
this.total = res.data.meta.total;
});
} if(!this.search && !this.pagination.sortBy) {
axios.get(`${environment.apiUrl}/category?page=${this.pagination.page}&per_page=${this.pagination.rowsPerPage}`)
.then(res => {
this.categories = res.data.data;
this.total = res.data.meta.total;
})
.catch(err => console.log(err.response.data))
.finally(() => this.loading = false);
}
}
}
}
in html part
<v-text-field v-model="search"
append-icon="search"
label="Search"
single-line
hide-details
></v-text-field>
<v-data-table :headers="headers"
:items="categories"
:pagination.sync="pagination"
:total-items="total"
:rows-per-page-items="rowsPerPageItems"
:loading="loading"
></v-data-table>
Laravel partでは、laravel scout
パッケージを使用しました。

サーバー側の検索を有効にするには、検索プロパティをv-data-tableに渡さないでください。そうしないと、「totalItems」プロパティを渡しても、データテーブルのページネーションと検索はクライアント側になります。
