Django中for循环中的动态值更改

Question

您好如何在for循环中传递动态值。在value={{ product.size.0.size }}中 而不是0，我想传递索引值

{% for no_of in product.size %}
{{ forloop.counter }}
<div class="row">
    <div class="col-sm-6">
        <div class="form-group">
            <label or="">Product Size</label> <input class="form-control" placeholder="Alpha-Numeric characters"
                required="required" type="text" name="product_size" id="product_size" value="{{ product.size.0.size }}">
            <div class="help-block form-text with-errors form-control-feedback"></div>
        </div>
    </div>
</div>

不，你不知道。您已经在遍历实际列表，而不是数字。

$services = Service::all()->makeHidden(['appendField1', 'appendField2'])->toArray();
