以下代码中的 id 值是什么？id 究竟是什么生成的？它是生成选择 1 还是只生成 1？ [关闭]

Question

{% for choice in question.choice_set.all %}

        <input type="radio" name="choice" id="choice{{ forloop.counter }}" value="{{ choice.id }}">

        <label for="choice{{ forloop.counter }}">{{ choice.choice_text }}</label><br>
{% endfor %}

Answer 1

假设 question.choice_set.all 有 4 个项目。

[
    {"id": 0, "choice_text": "Choice 1"},
    {"id": 1, "choice_text": "Choice 2"},
    {"id": 2, "choice_text": "Choice 3"},
    {"id": 3, "choice_text": "Choice 4"},
]

生成的代码将如下所示：

<input type="radio" name="choice" id="choice1" value="0">
<label for="choice1">Choice 1</label><br>
<input type="radio" name="choice" id="choice2" value="1">
<label for="choice2">Choice 2</label><br>
<input type="radio" name="choice" id="choice3" value="2">
<label for="choice3">Choice 3</label><br>
<input type="radio" name="choice" id="choice4" value="3">
<label for="choice4">Choice 4</label><br>
