具有不同数据源烧瓶的多个数据表，ajax

Question

我有 2 个数据table，我这样填充一个

{% block scripts %}
<script>
    $(document).ready(function () {
      $('#data').DataTable({
        ajax: '/api/data',
        columns: [
          {data: 'PR Number'},
          {data: 'Short Description'},
          {data: 'PR Text'},
          {data: 'Developer Scratchpad'},
          {data: 'Final Response'},
          {data: 'Rating'},
          { sortable: false,
            "render": function(data, type, row, meta) {
                return '<a href="http://webtac.industrysoftware.automation.siemens.com/webpr/webpr.php?objtype=shortcut&startlink=view&startoption=reuse_last_session&startdata='+ row['PR Number'] +'"  target="_blank">Show PR in WebTac</a>';
              }
            },
          { sortable: false,
            "render": function(data, type, row, meta) {
                return '<a href="' + window.location.origin + '/details/' + row['PR Number'] +'" class="btn btn-outline-success">Show additional details</a>';
              }
            }
        ],
      });
    });

</script>
{% endblock %}

当我想再做一个这样的时候

{% block scripts %}
<script>
    $(document).ready(function () {
      $('#dataDetails').DataTable({
        "ajax": {
        "url": '/api/dataDetails',
        "dataSrc": ""
        },
        "columns": [
          {dataDetails: 'PR id'},
          {dataDetails: 'Author'},
          {dataDetails: 'Date'},
          {dataDetails: 'Description'},
          {dataDetails: 'File name'},
          {dataDetails: 'Reviewer'},
          {dataDetails: 'Story id'}
        ],
      });
    });

</script>
{% endblock %}

它给我以下错误

DataTables 警告：tableid=dataDetails - 无法重新初始化 DataTable。有关此错误的详细信息，请参阅 http://datatables.net/tn/3

关于如何使具有不同数据源的两个数据table在同一个应用程序中工作有什么想法吗？谢谢

Answer 1

正如我之前解释的，我假设您对同一个 ID #dataDetails 使用了两次 DataTables(...) 命令。因此没有必要绕过该命令，只是为了避免使用相同的 id 调用它两次。

在下面的示例中，您可以看到可以使用多个 table，前提是每个 id 仅与 DataTables(...) 命令一起使用一次。
第一个调用引用 ID 为 #table-1 的 table，第二个调用引用 ID 为 #table-2.

的 table

from flask import (
    Flask,
    jsonify,
    render_template
)

app = Flask(__name__)

@app.route('/')
def index():
    return render_template('index.html')

@app.route('/api/data1')
def api_data1():
    data = [
        {
            'PR Number': i,
            'Short Description': 'Your description here.'
        } for i in range(10)
    ]
    return jsonify(data=data)

@app.route('/api/data2')
def api_data2():
    data = [
        {
            'PR id': (i + 1),
            'Author': f'Author-{i + 1}'
        } for i in range(20)
    ]
    return jsonify(dataDetails=data)
