evalcontextfilter and evalcontextfunction are replaced by pass_eval_context. environmentfilter and environmentfunction are replaced by pass_environment. 所以可能会有人在使用的过程中出现这样的问题module 'jinja2' has no attribute "'contextfunction'". 这种时候完全不用慌, 只需要安装最新版的fastapi即可, ...
Each node has two attributes: lineno (the line number of the node) and environment. The environment attribute is set at the end of the parsing process for all nodes automatically. find(node_type) Find the first node of a given type. If no such node exists the return value is None. ...
If no else node exists it has to be an empty list. For filtered nodes an expression can be stored as test, otherwise None. Node type: Stmt class jinja2.nodes.FromImport(template, names, with_context)¶ A node that represents the from import tag. It’s important to not pass unsafe ...
上下文过滤器工作方式相同,只是第一个参数是当前活动的 Context而 不是环境。求值上下文 求值上下文(缩写为 eval context 或 eval ctx )是 Jinja 2.4 中引入的新对象,并可以在运行时激活/停用已编译的特性。 当前它只用于启用和禁用自动转义,但也可以用于扩展。 在之前的 Jinja 版本中,过滤器和函数被标记为环境...

本方法只能用于python2,因为在python3中会报错'function object' has no attribute 'func_globals',猜测应该是python3中func_globals被移除了还是啥的,如果不对请师傅们指出 我们把上面的find.py脚本中的search变量赋值为linecache,去寻找含有linecache的类
