Magento 2 – Understanding ‘at_call’ in Layout File

layoutmagento2

I often see "at_call" in the tag of a layout like below, what is this for? what it functions as? Thank you.

<block class="Magento\Catalog\Block\Product\View\Description" name="product.info.sku" template="product/view/attribute.phtml" after="product.info.type">
    <arguments>
        <argument name="at_call" xsi:type="string">getSku</argument>
        <argument name="at_code" xsi:type="string">sku</argument>
        <argument name="css_class" xsi:type="string">sku</argument>
        <argument name="at_label" xsi:type="string">default</argument>
        <argument name="add_attribute" xsi:type="string">itemprop="sku"</argument>
    </arguments>
</block>

it is used in the template to determine the function call to get the attribute. I think this is short for attribute_call

Here is the location in the template: https://github.com/magento/magento2/blob/develop/app/code/Magento/Catalog/view/frontend/templates/product/view/attribute.phtml#L18

The arguments from the layout are inserted into the data array of the Block. The getAtCall() Method in the template is internally translated to getData('at_call') which then retrieves the value from the layout file.

Suppose package:Learning and module: Custom

Module.xml looks like

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../lib/internal/Magento/Framework/Module/etc/module.xsd">
    <module name="Learning_Custom" setup_version="2.0.0">
        <sequence>
            <module name="Magento_Catalog"/>
        </sequence>
    </module>
</config>

And then create a layout xml following path -> app/code/Learning/Custom/view/frontend/layout/catalog_product_prices.xml

<layout xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../../../lib/internal/Magento/Framework/View/Layout/etc/layout_generic.xsd">
    <referenceBlock name="render.product.prices">
        <arguments>
            <argument name="default" xsi:type="array">
                <item name="prices" xsi:type="array">
                    <item name="tier_price" xsi:type="array">
                        <item name="render_template" xsi:type="string">Learning_Custom::product/price/tier_prices.phtml
                    </item>
                </item>
            </argument>
        </arguments>
    </referenceBlock>
</layout>

Create template inside your module or copy base template file inside your module path should be -> app/code/Learning/Custom/view/frontend/templates/product/price/tier_prices.phtml
