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。
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。

請注意，塊content_wrapper用于呈現每個頁面的自定義內容。
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。

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 %}
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> <input type="text" class="form-control is-invalid" id="inputError" placeholder="Enter ..."> </div> <div class="row"> <div class="col-sm-6"> <!-- checkbox --> <div class="form-group"> <div class="form-check"> <input class="form-check-input" type="checkbox"> <label class="form-check-label">Checkbox</label> </div> <div class="form-check"> <input class="form-check-input" type="checkbox" checked> <label class="form-check-label">Checkbox checked</label> </div> <div class="form-check"> <input class="form-check-input" type="checkbox" disabled> <label class="form-check-label">Checkbox disabled</label> </div> </div> </div> <div class="col-sm-6"> <!-- radio --> <div class="form-group"> <div class="form-check"> <input class="form-check-input" type="radio" name="radio1"> <label class="form-check-label">Radio</label> </div> <div class="form-check"> <input class="form-check-input" type="radio" name="radio1" checked> <label class="form-check-label">Radio checked</label> </div> <div class="form-check"> <input class="form-check-input" type="radio" disabled> <label class="form-check-label">Radio disabled</label> </div> </div> </div> </div> <div class="row"> <div class="col-sm-6"> <!-- select --> <div class="form-group"> <label>Select</label> <select class="form-control"> <option>option 1</option> <option>option 2</option> <option>option 3</option> <option>option 4</option> <option>option 5</option> </select> </div> </div> <div class="col-sm-6"> <div class="form-group"> <label>Select Disabled</label> <select class="form-control" disabled> <option>option 1</option> <option>option 2</option> <option>option 3</option> <option>option 4</option> <option>option 5</option> </select> </div> </div> </div> <div class="row"> <div class="col-sm-6"> <!-- Select multiple--> <div class="form-group"> <label>Select Multiple</label> <select multiple class="form-control"> <option>option 1</option> <option>option 2</option> <option>option 3</option> <option>option 4</option> <option>option 5</option> </select> </div> </div> <div class="col-sm-6"> <div class="form-group"> <label>Select Multiple Disabled</label> <select multiple class="form-control" disabled> <option>option 1</option> <option>option 2</option> <option>option 3</option> <option>option 4</option> <option>option 5</option> </select> </div> </div> </div> </form>
刪除Landing.html和index.html中的多余表單代碼。使用{％ include ‘advanced_forms/general_elements_form.html’ ％}包含表單。設置好之后，這就是最終結果。
