django学习笔记-模板语法

1. 参数传递

    name = "张三"
    alist = ['a', 'b', 'c']
    adict = {"name": "张三", "role": "管理员", "gender": "男"}
    data_list = [
        {"name": "张三", "role": "管理员", "gender": "男"},
        {"name": "李四", "role": "成员", "gender": "男"},
        {"name": "王五", "role": "成员", "gender": "男"}
    ]
    return render(
        request,
        "test1.html",
        {"n1": name, "n2": alist, "n3": adict, "n4": data_list}
    )

2. 模板语法

2.1 普通参数

<div>{{ n1 }}</div>

2.2 列表参数

<div>{{ n2 }}</div>
<div>{{ n2.0 }}</div>
<div>{{ n2.1 }}</div>
<div>{{ n2.2 }}</div>
{% for item in n2 %}
    <span>{{ item }}</span>
{% endfor %}

2.3 字典参数

<div>{{ n3 }}</div>
<div>{{ n3.name }}</div>
<div>{{ n3.role }}</div>
<div>{{ n3.gender }}</div>
<ul>
    {% for key,value in n3.items %}
        <li>{{ key }}:{{ value }}</li>
    {% endfor %}
</ul>

2.4 列表字典混合

<table>
    <thead>
        <tr>
            {% for key in n4.0.keys %}
                <th>{{ key }}</th>
            {% endfor %}
        </tr>
    </thead>
    <tbody>
        {% for item in n4 %}
            <tr>
                <td>{{ item.name }}</td>
                <td>{{ item.role }}</td>
                <td>{{ item.gender }}</td>
            </tr>
        {% endfor %}
    </tbody>
</table>

2.5 if判断

{% if n1 == "a" %}
    <div>a</div>
{% elif n1 == "b" %}
    <div>b</div>
{% else %}
    <div>c</div>
{% endif %}
