如何为ngFor中的每个元素显示模态?

我知道以前有人问过这个问题,我也尝试过提出的解决方案,但没有一个对我有效。

因此,我有一个带有书籍列表的仪表板,我制作了一个模式,在单击书籍时显示,以显示书籍详细信息

<div class="container">
  <div class="row">
    <div class="col-md-3" *ngFor="let p of (Publications | sort: pubSort)">
      <figure class="card card-product">
        <div class="img-wrap">
          <img
            src="{{ p.URL_couv }}"
            alt="{{ p.id }}"
            data-toggle="modal"
            data-target="#p"
          />
        </div>
        <figcaption class="info-wrap">
          <h6 class="title text-dots">{{ p.titre }} n° {{ p.numero }}</h6>
          <div class="action-wrap">
            <div class="price-wrap">
              {{ p.date_parution }}
