这是一个CRUD编辑页面的模板页面，当我们渲染这个编辑页面时，除了图像之外，所有已经上传的字段都会显示出来，我们如何在图像字段中看到已经上传的图像，希望你们明白了。
<body>
<div class="row">
<div class="col-sm-4">
<h1 class="text-center alert alert-info">Modify Order Details</h1>
<form action="" method="POST" enctype="multipart/form-data">
{% csrf_token %}
<label for="category">Select a Category :- </label>
<select name="category" id="category">
<option value="None"selected >None</option>
<option value="Tshirt" {% if products.category == 'Tshirt' %} selected {% endif %}>Tshirt</option>
<option value="Jeans" {% if products.category == 'Jeans' %} selected {% endif %}>Jeans</option>
<option value="Jacket" {% if products.category == 'Jacket' %} selected {% endif %}>Jacket</option>
<option value="Shoes" {% if products.category == 'Shoes' %} selected {% endif %} >Shoes</option>
<option value="Watch" {% if products.category == 'Watch' %} selected {% endif %} >Watch</option>
</select> <br><br>
<label for="product_name">Select a Product: </label>
<select name="product_name" id="product_name" value="{{products.product_name}}" >
<option value="{{products.product_name}}" selected readonly >{{products.product_name}}</option>
</select><br><br><br>
<label for="product_price">Product Price:</label>
<input type="text" id="product_price" class="form-control" name="product_price" value="{{products.product_price}}" pattern="^[^ ].+[^ ]$" title="Please Remove Extra Spaces" required><br>
<label for="supplier_images">Image:</label>
<input type="file" name="image"></a> <br><br>
<!-- <span>Current image:</span> <img src="{{products.image.url}}" alt="" width="40"> -->
<br><br>
<input type="submit" value="Update" class="btn btn-success">
</form>
</div>
</div><br><br>
<h3><a href="{% url 'supplier_dashboard' %}">Back</a></h3>
假设您使用 django 模板来显示上传的图像，您可以这样做：
{% if products.image.url %}
<span>Current image:</span> <img src="{{products.image.url}}" alt="Current Image" width="100">
{% endif %}
