How should a record be removed from a database which is using a model that was inherited from the \Magento\Framework\Model\AbstractModel class?
The 'delete' method on the \Magento\Framework\Model\AbstractModel class is used to remove a record from the database. This method will also cascade the delete to any related records.
In Magento, models that inherit from the \Magento\Framework\Model\AbstractModel class interact with the database through the ORM (Object-Relational Mapping) layer. To remove a record from the database using such a model, the delete method is used. This method encapsulates the logic for deleting the record associated with the model instance from its corresponding database table. By calling $model->delete(), where $model is an instance of a model inheriting from AbstractModel, Magento will perform the necessary operations to remove the record from the database, ensuring data integrity and consistency within the application.
A developer has informed the Adobe Support team about a planned traffic surge on an Adobe Commerce Cloud project that will take place in a little over 48 hours.
What is an advantage of this prior notice?
Informing the Adobe Support team about a planned traffic surge allows them to monitor the website during that time. With prior notice, the support team can ensure that they are prepared to quickly respond to any issues that arise due to the surge. While extra server resources or an upgraded Fastly plan may be possible outcomes, the primary advantage of advance notice is proactive monitoring and support during expected high traffic events.
Which two methods add sorting to collections inherited from the \Magento\Framework\Model\ResourceModel\Db\Collection\AbstractCollection class? (Choose two.)
The two methods that add sorting to collections inherited from the \Magento\Framework\Model\ResourceModel\Db\Collection\AbstractCollection class are setOrder and addOrder. These methods allow adding one or more order clauses to a collection query.
The setSorting and addSorting methods do not exist in Adobe Commerce.
Verified Reference: [Adobe Commerce Developer Guide - Collections]
In Magento 2, collections inherited from \Magento\Framework\Model\ResourceModel\Db\Collection\AbstractCollection class can be sorted using the setOrder and addOrder methods. The setOrder method is used to set the order for a field in the collection, specifying the field by which to sort and the direction of the sorting (ASC or DESC). The addOrder method is similar but allows for adding multiple sorting orders to the collection, enabling more complex sorting scenarios. There are no setSorting or addSorting methods in the standard Magento 2 collection classes.
Which action, if any, should be taken to enable filtering by attribute in the category's layered navigation?
To enable filtering by attribute in a category's layered navigation, you should set the category's 'Is Anchor' setting to 'Yes'. This setting is found in the category's display settings within the admin panel. When a category is set as 'Anchor', Magento will automatically include filtering options in the layered navigation block for all attributes that are configured to be used in layered navigation.
Which log file would help a developer to investigate 503 errors caused by traffic or insufficient server resources on an Adobe Commerce Cloud project?
To check the access.log file on an Adobe Commerce Cloud project, a developer can use the following command in the CLI:
grep -r '\' 50 [0-9]' /path/to/access.log
Alternatively, if the error has occurred in the past and the access.log file has been rotated (compressed and archived), the developer can use the following command in the CLI (Pro architecture only):
zgrep '\' 50 [0-9]' /path/to/access.log.<rotation ID>.gz
