[英]Adding debug traces to Symfony 3.4 twig templates during/after render
I am looking for a seamless way to do this.我正在寻找一种无缝的方式来做到这一点。
With Symfony 3.4, I need a way to, having a rendered page, know, for any element/text, which twig template it comes from.使用 Symfony 3.4,我需要一种方法,让渲染页面知道,对于任何元素/文本,它来自哪个树枝模板。
NOTE: I have checked Twig - display template names if debug mode is enabled , but that thread is about using Twig but no Symfony.注意:我已经检查了Twig - 如果启用了调试模式,则显示模板名称,但该线程是关于使用 Twig 而不是 Symfony。 I have been following the examples there but without results.
我一直在关注那里的例子,但没有结果。
I would like to not just add tracing data in every template, but to have the minimum possible invasive code needed to, for example, add to the starting point of a twig file and at the end of the file.我不仅希望在每个模板中添加跟踪数据,而且还希望具有所需的最小侵入性代码,例如,添加到树枝文件的起点和文件末尾。
As there are blocks as well, the same but something like <trace twig="…" block="…"/>
, etc, to each one of those blocks.由于也有块,对于这些块中的每一个,相同但类似于
<trace twig="…" block="…"/>
等。
(Of course style=“display:none” in those marks) (当然这些标记中的样式=“显示:无”)
I have put the other quoted question template at templates/DebugTemplate.php, app/templates/debugTemplate.php, and src/AppBundle/Twig/DebugTemplate.php我已将另一个引用的问题模板放在 templates/DebugTemplate.php、app/templates/debugTemplate.php 和 src/AppBundle/Twig/DebugTemplate.php
I went to app/config/config.yml and added twig->base_template_class, but I do not know how to correctly make this configuration work.我去了 app/config/config.yml 并添加了 twig->base_template_class,但我不知道如何正确地使这个配置工作。
I have understood that you just have to write the template name directly like:我明白你只需要直接写模板名称,如:
# Twig Configuration
twig:
debug: '%kernel.debug%'
strict_variables: '%kernel.debug%'
base_template_class: DebugTemplate
But it crashes with Unexpected characters (}) at line 116 (near "base_template_class: {'DebugTemplate'}")但它在第 116 行(“base_template_class: {'DebugTemplate'}”附近)因意外字符 (}) 而崩溃
Same with同
base_template_class: Twig\DebugTemplate
base_template_class: 'Twig\DebugTemplate'
base_template_class: {'Twig\DebugTemplate'}
base_template_class: 'DebugTemplate'
base_template_class: "%kernel.root_dir%/templates/DebugTemplate"
base_template_class: "%kernel.root_dir%\\templates\\DebugTemplate"
base_template_class: templates\\DebugTemplate
Checking config via console: php bin/console debug:config twig通过控制台检查配置:php bin/console debug:config twig
Current configuration for extension with alias "twig"
=====================================================
twig:
debug: true
strict_variables: true
base_template_class: DebugTemplate
exception_controller: 'twig.controller.exception:showAction'
form_themes:
- form_div_layout.html.twig
globals: { }
autoescape: name
autoescape_service: null
autoescape_service_method: null
cache: /NFS/code/nabc/abc_frontal_service/var/cache/dev/twig
charset: UTF-8
default_path: /NFS/code/nabc/abc_frontal_service/templates
paths: { }
date:
format: 'F j, Y H:i'
interval_format: '%d days'
timezone: null
number_format:
decimals: 0
decimal_point: .
thousands_separator: ','
Using the next config example (others do not generate the cache file): base_template_class: templates\\DebugTemplate使用下一个配置示例(其他人不生成缓存文件):base_template_class:templates\\DebugTemplate
It is generated, in cache, a class that tryes to extend the configurated template:它在缓存中生成一个尝试扩展配置模板的类:
class __TwigTemplate_f3b8c130edb93e6c111c9714c114a4cede8e75482f6253fab3adbfd0ccca6c5e extends \templates\\DebugTemplate
This class is not always renewed when I change the config, so I suppose that what I typed in the config was not considered valid.当我更改配置时,这个类并不总是更新,所以我认为我在配置中输入的内容不被认为是有效的。
So I have two problems:所以我有两个问题:
How to do this in Symfony 3.4 (I do not know about other versions), based on Twig - display template names if debug mode is enabled and @DarkBee helping hands!如何在 Symfony 3.4(我不知道其他版本)中执行此操作,基于Twig - 如果启用调试模式和@DarkBee 帮助显示模板名称!
Create your template class.创建您的模板类。 Example: src/YourCompany/Application/TWIG/Helper/DebugTemplate.php
示例:src/YourCompany/Application/TWIG/Helper/DebugTemplate.php
\n namespace YourCompany\\Application\\TWIG\\Helper;命名空间 YourCompany\\Application\\TWIG\\Helper;\n use Twig_Template;
使用 Twig_Template;\n\n abstract class DebugTemplate extends Twig_Template {
抽象类 DebugTemplate 扩展了 Twig_Template {\n public function display(array $context, array $blocks = array())
公共函数显示(数组 $context,数组 $blocks = array())\n {
{\n // workaround - only add the html comment when the partial is loaded with @
// 解决方法 - 仅在使用 @ 加载部分时添加 html 注释\n if(substr($this->getTemplateName(),0,1) == '@') {
if(substr($this->getTemplateName(),0,1) == '@') {\n echo 'getTemplateName() .
echo 'getTemplateName() 。 ' -->';
'-->';\n }
}\n\n $this->displayWithErrorHandling($this->env->mergeGlobals($context), array_merge($this->blocks, $blocks));
$this->displayWithErrorHandling($this->env->mergeGlobals($context), array_merge($this->blocks, $blocks));\n\n if(substr($this->getTemplateName(),0,1) == '@') {
if(substr($this->getTemplateName(),0,1) == '@') {\n echo 'getTemplateName() .
echo 'getTemplateName() 。 ' -->';
'-->';\n }
}\n\n }
}\n }
}\n
go to config.yml.转到 config.yml。 In my project its path is app/config/config.yml.
在我的项目中,它的路径是 app/config/config.yml。 Add the base_template_class setting under the twig section using our new namespace\\className as the value.
使用我们新的 namespace\\className 作为值,在 twig 部分下添加 base_template_class 设置。 Example:
例子:
\n ......\n\n # Twig Configuration
# 树枝配置\n twig:
枝条:\n debug: '%kernel.debug%'
调试: '%kernel.debug%'\n strict_variables: '%kernel.debug%'
strict_variables: '%kernel.debug%'\n base_template_class: YourCompany\\Application\\TWIG\\Helper\\DebugTemplate
base_template_class: YourCompany\\Application\\TWIG\\Helper\\DebugTemplate\n\n
