Django materializecss datatable jquery

Я пытаюсь получить Uncaught ReferenceError: jQuery is not defined и Uncaught ReferenceError: $ is not defined при попытке загрузить выпадающий Select2 с datepicker. Я использую Materializecss, Datatables и jQuery с Django. Как я могу правильно структурировать base.html, чтобы все необходимые css, javascript и jquery загружались только один раз? Ниже приведен мой код для base.html, topsearchbar.html и dashboard.html (который выдает вышеуказанные ошибки)

base.html

topsearchbar.html

<div class="row" style="margin-top: 25px;">
    <div class="col s3 center">
        <select id="selItemType" name="itemtype">
            <option disabled-selected value="">
                Select Item Type
            </option>
            <option value="1">Item 1</option>
            <option value="2">Item 2</option>
            <option value="3">Item 3</option>
        </select>
    </div>


    <div class="col s3 center">
        <div class="input-field">
            <input class="datepicker" id="start_date" name="start_date" required type="text">
            <label for="start_date">From Date</label>
        </div>
    </div>
    <div class="col s3 center">
        <div class="input-field">
            <input class="datepicker" id="end_date" name="end_date" required type="text">
            <label for="end_date">To Date</label>
        </div>
    </div>

</div>

<script>
    $(document).ready(function(){
        $('#selItemType').select2();
    });
</script>

<script>
  $(document).ready(function(){
    $('#start_date').datepicker({
        dateFormat: 'dd-M-yy'
    });
    $('#end_date').datepicker({
        dateFormat: 'dd-M-yy'
    });
  });
</script>
