Check if the value is escaped. even(value)¶ Return true if the variable is even. iterable(value)¶ Check if it’s possible to iterate over an object. lower(value) Return true if the variable is lowercased.
Personally I would advise against testing non-boolean types for truthiness. There aren't that many cases where this could be useful and it might make your intent non-obvious. If you simply want to check if the variable exists thenis definedtest, which we'll look at shortly, is usually a ...
Check if the value is escaped. even(value) Return true if the variable is even. iterable(value) Check if it’s possible to iterate over an object. lower(value) Return true if the variable is lowercased. mapping(value) Return true if the object is a mapping (dict etc.). New in versi...

Looks up a variable like__getitem__orgetbut returns anUndefinedobject with the name of the name looked up. 实现 Python frame 中的局域变量在函数中是不可变的,出于同样的原因,上下文是不可 变的。 Jinja2 和 Python 都不把上下文/ frame 作为变量的数据存储,而只作为 主要的数据源。
If no such node exists the return value is None. find_all(node_type) Find all the nodes of a given type. If the type is a tuple, the check is performed for any of the tuple items. iter_child_nodes(exclude=None, only=None) Iterates over all direct child nodes of the node. This...

Closely related to 'ignore missing' is possibility of providing list of templates to include. Jinja will check templates for existence, including the first one that exists. In the below example, iflocal_users.j2does not exist butradius_users.j2does, then renderedradius_users.j2will end up bein...
