[英]How to add a root name and child name to drupal view REST?
I have a doubt, i've created a REST with View and i formated like JSON, but the output is like this:我有一个疑问,我已经创建了一个带有 View 的 REST 并且我的格式类似于 JSON,但是 output 是这样的:
[{"item1":"123","item2":"123","item3":"123","item4":"","item5":"123","item5":"123"}, {"item1":"345","item2":"345","item3":"345","item4":"","item5":"345","item5":"345"}]
And i need something like this:我需要这样的东西:
{"elements":
[
{"element":
{"item1":"123","item2":"123","item3":"123","item4":"123","item5":"123"}
},
{"element": {"item1":"345","item2":"345","item3":"345","item4":"345","item5":"345"}
}
]
}
How can i add a root name and child name?如何添加根名称和子名称? is some configuration on views that i can do?我可以对视图进行一些配置吗?
I've tried with views_post_execute hook like this:我试过像这样使用 views_post_execute 钩子:
function mymodule_views_post_execute(ViewExecutable $view) {
if (isset($view) && ($view->storage->id() == 'myrestjson')) {
$result = ['elements' => array_map(
function ($subarray) {
return ['element' => $subarray];
},$view->result
)];
$view->result = $result;
}
}
but i'm getting this error:但我收到此错误:
TypeError: Argument 1 passed to Drupal\views\Plugin\views\field\FieldPluginBase::advancedRender() must be an instance of Drupal\views\ResultRow,array given, called in mysite\core\modules\rest\src\Plugin\views\row\DataFieldRow.php on line 147 in Drupal\views\Plugin\views\field\FieldPluginBase->advancedRender() (line 1142 of core\modules\views\src\Plugin\views\field\FieldPluginBase.php).
Could you please help me?请你帮助我好吗? Regards Mario问候马里奥
You can use a custom Serializer
to alter the output:您可以使用自定义Serializer
程序来更改 output:
.../your_module/src/Plugin/views/style/CustomSerializer.php
.在您的自定义模块中创建一个新的自定义序列化程序 class ,路径为: .../your_module/src/Plugin/views/style/CustomSerializer.php
。Serializer
class: Drupal\rest\Plugin\views\style\Serializer.php
自定义序列化器 class 应从核心Serializer
器 class 扩展: Drupal\rest\Plugin\views\style\Serializer.php
render()
method (you can compare with core Serializer
class to see what I modified)覆盖render()
方法(可以和core Serializer
class比较看看我修改了什么)<?php
namespace Drupal\your_module\Plugin\views\style;
use Drupal\rest\Plugin\views\style\Serializer;
/**
* The style plugin for serialized output formats.
*
* @ingroup views_style_plugins
*
* @ViewsStyle(
* id = "custom_serializer",
* title = @Translation("Custom serializer"),
* help = @Translation("Serializes views row data using the Serializer
* component."), display_types = {"data"}
* )
*/
class CustomSerializer extends Serializer {
/**
* {@inheritdoc}
*/
public function render() {
$rows = [];
foreach ($this->view->result as $row_index => $row) {
$this->view->row_index = $row_index;
$rows[] = ['element' => $this->view->rowPlugin->render($row)];
}
unset($this->view->row_index);
if ((empty($this->view->live_preview))) {
$content_type = $this->displayHandler->getContentType();
}
else {
$content_type = !empty($this->options['formats']) ? reset($this->options['formats']) : 'json';
}
return $this->serializer->serialize(['elements' => $rows], $content_type, ['views_style_plugin' => $this]);
}
}
