        在本文中,我將介紹在Django應用程序開發中設計Django模板的方法。目的是保持Django應用程序的UI部分井井有條,并避免重復編碼。Django在模板引擎中提供了各種機制來幫助我們實現這一目標。在本教程中,我將說明如何使用Django內置模板標記塊,擴展和包含來使模板易于維護。

        準備工作:

        1、Python 3.6

        2、Django 2.2

        3、AdminLTE 3.0.5

        我們目標是將模板文件有效組織起來,避免重復的代碼引用,我們分四個步驟來實現。

        步驟1/4:base.html

        將模板分為多個部分,我們知道除了菜單和內容外,其他所有內容都是可重復的。 我們將制作一個基本模板來容納那些常見的部分,如圖:

        在項目文件夾中創建一個文件夾模板。 在其中創建一個base.html。 將所有常見的片段添加到其中。只需復制并粘貼以下內容,僅是load.html和index.html共享的一部分代碼。

        步驟2/4:刪除冗余的通用代碼

        由于我們在上一步中創建了base.html,因此不再需要將通用代碼保留在Landing.html和home.html中。 我們應該得到如下結果。

            </div><!-- /.container-fluid -->

          <!-- /.content -->
        </div>
        

        步驟3/4:繼承base.html

        為了將base.html用作每個頁面的基礎模板,我們需要通過在模板的開頭使用{%extended‘base.html’%}來聲明base.html為“父”模板。 最重要的是,不要忘記content_wrapper塊。 將全部內容包裝到該塊中。 我們應該得到如下結果。

        landing.html:
        
        {% extends 'base.html' %}
        {% load static %}
        {% block content_wrapper %}
          <div class="content-wrapper">
            . . .
          </div>
        {% endblock %}
        

        在index.html:

        {% extends 'base.html' %}
        {% load static %}
        {% block content_wrapper %}
          <div class="content-wrapper">
            . . .
          </div>
        {% endblock %}
        

        步驟4/4:將常見的內容單獨存放

        現在我們可能會意識到,兩個模板中都存在相同的巨型形式。幾乎一半的代碼是它。由于此表單已在兩個模板中重復使用,因此我們將其維護在一個可以包含任何模板的地方。

        在模板文件夾中創建一個文件夾advanced_forms。 在advanced_forms文件夾中,創建如下的general_elements_form.html,代碼如下:

        <form role="form">
          <div class="row">
            <div class="col-sm-6">
              <!-- text input -->
              <div class="form-group">
                <label>Text</label>
                <input type="text" class="form-control" placeholder="Enter ...">
              </div>
            </div>
            <div class="col-sm-6">
              <div class="form-group">
                <label>Text Disabled</label>
                <input type="text" class="form-control" placeholder="Enter ..." disabled>
              </div>
            </div>
          </div>
          <div class="row">
            <div class="col-sm-6">
              <!-- textarea -->
              <div class="form-group">
                <label>Textarea</label>
                <textarea class="form-control" rows="3" placeholder="Enter ..."></textarea>
              </div>
            </div>
            <div class="col-sm-6">
              <div class="form-group">
                <label>Textarea Disabled</label>
                <textarea class="form-control" rows="3" placeholder="Enter ..." disabled></textarea>
              </div>
            </div>
          </div>
        
          <!-- input states -->
          <div class="form-group">
            <label class="col-form-label" for="inputSuccess"><i class="fas fa-check"></i> Input with
              success</label>
            <input type="text" class="form-control is-valid" id="inputSuccess" placeholder="Enter ...">
          </div>
          <div class="form-group">
            <label class="col-form-label" for="inputWarning"><i class="far fa-bell"></i> Input with
              warning</label>
            <input type="text" class="form-control is-warning" id="inputWarning" placeholder="Enter ...">
          </div>
          <div class="form-group">
            <label class="col-form-label" for="inputError"><i class="far fa-times-circle"></i> Input with
              error</label>

        寫在最后,模板是Web應用程序中的核心部分之一。 不要寫重復代碼,我認為該原則適用于前端和后端開發,這樣我們才可以制作出可伸縮的應用程序。
