Django学习-5-模板渲染
1. {{ 变量名 }}
def func(request):
return render(request, "index.html", {'current_user': "alex"})
index.html
<html>
..
<body>
<div>{{current_user}}</div>
</body>
</html>
====> 最后生成的字符串
2.For循环
def func(request):
return render(request, "index.html", {'current_user': "alex", 'user_list': ['alex','eric']})
index.html
<html>
..
<body>
<div>{{current_user}}</div>
<ul>
{% for row in user_list %}
{% if row == "alex" %}
<li>{{ row }}</li>
{% endif %}
{% endfor %}
</ul>
</body>
</html>
3. 索引
def func(request):
return render(request, "index.html", {
'current_user': "alex",
'user_list': ['alex','eric'],
'user_dict': {'k1': 'v1', 'k2': 'v2'}})
index.html
<html>
..
<body>
<div>{{current_user}}</div>
<a> {{ user_list.1 }} </a>
<a> {{ user_dict.k1 }} </a>
<a> {{ user_dict.k2 }} </a>
</body>
</html>
4.条件判断
def func(request):
return render(request, "index.html", {
'current_user': "alex",
"age": 18,
'user_list': ['alex','eric'],
'user_dict': {'k1': 'v1', 'k2': 'v2'}})
index.html
<html>
..
<body>
<div>{{current_user}}</div>
<a> {{ user_list.1 }} </a>
<a> {{ user_dict.k1 }} </a>
<a> {{ user_dict.k2 }} </a>
{% if age %}
<a>有年龄</a>
{% if age > 16 %}
<a>老男人</a>
{% else %}
<a>小鲜肉</a>
{% endif %}
{% else %}
<a>无年龄</a>
{% endif %}
</body>
</html>
默认循环字典时，取的是key
｛%for i in dic%｝
{{i}} keys
{%endfor%}
｛%for i in dic.keys%｝
{{i}} keys 键
{%endfor%}
{%for i in dic.values%｝
{{i}} vaules 值
{%endfor%}
{%for i,j in dic.items%｝ 键值对
{{i}},{{j}} (key,vaules)
{%endfor%}
