模板引擎使用示例
|
|
|
|
基础用法:
|
|
1. 简单变量替换: {{variable}}
|
|
2. 条件判断: {% if condition %}...{% endif %}
|
|
3. 循环结构: {% for item in items %}...{% endfor %}

from core.lax import TemplateParser
|
|
|
|
|
|
from core.models import Feed, Article
|
|
from core.db import DB
|
|
# 示例4: 使用Feed和Article模型数据
|
|
feed_template = """
|
|
### {{feed.mp_name}} 订阅消息：
|
|
{% if articles %}
|
|
{% for article in articles %}
|
|
- [**{{ article.title }}**]({{article.url}}) ()
|
|
{{=__import__('datetime').datetime.strftime(datetime.fromtimestamp(article.publish_time), "%Y/%m/%d %H:%M")}}
|
|
{{=__import__('datetime').datetime.now().strftime('%Y-%m-%d %H:%M:%S')}}
|
|
{% endfor %}
|
|
{% else %}
|
|
- 暂无文章\n
|
|
{% endif %}
|
|
|
|
Eval表达式示例:
|
|
1. 文章数量: {{=len(articles)}}
|
|
2. 名称大写: {{=feed['mp_name'].upper()}}
|
|
3. 最新日期: {{=__import__('datetime').datetime.strftime(__import__('datetime').datetime.fromtimestamp(articles[0]['publish_time']), "%Y/%m/%d %H:%M").split()[0] if articles else '无'}}
|
|
4. 数学函数: 圆周率≈{{=__import__('math').pi}}
|
|
5. 随机数: {{=__import__('random').randint(1, 100)}}
|
|
6. 正则提取: {{=__import__('re').search(r'\d+', str(articles[0]['publish_time'])).group() if articles else ''}}
|
|
7. 当前时间: {{=__import__('datetime').datetime.now().strftime('%Y-%m-%d %H:%M:%S')}}
