如何在 Template Toolkit 模板文件中覆盖 WRAPPER? [英] How can I override WRAPPER in a Template Toolkit template file?

问题描述

有没有办法禁用在 WRAPPER="noreferrer">new(\%config)，通过模板，还是使用 parse() 临时覆盖?我想要一个默认的 WRAPPER(我将用于 99.9% 的模板)，但排除一些.

Is there a way to disabling a WRAPPER that was set in new(\%config), through either the template, or a temporary override with parse()? I want to have a single default WRAPPER (that I'll use for 99.9% of my templates), but exclude a few.

我正在通过 Catalyst::View::TT 完成这一切，就像 配置概要，除非我不希望 WRAPPER 应用于所有我的模板.

I'm doing this all through Catalyst::View::TT just like the example in the configuration synopsis, except I don't want the WRAPPER to apply to all of my templates.

推荐答案

编辑包装器，以包含如下条件:

Edit the wrapper, to include a conditional like:

[% IF no_wrapper OR template.no_wrapper %] [% content %] [% ELSE %]
  top;
    [% content %]
  bottom;
[% END %]

这允许我在 (1) 模板内部或 (2) 从存储中禁用包装器.

This allows me to disable the wrapper either (1) inside of template, or (2) from the stash.

1. [%- META no_wrapper = 1 -%]
2. $c->stash->{no_wrapper} = 1

META var ...; 是一个指令，它使 var 可以通过 template 哈希作为 template.var 访问代码>

META var ...; is a directive that makes var accessible through the template hash as template.var
