Symfony Api Platform – Not Filtered Duration: The Ultimate Guide to Mastering Time-Based Queries

If you’re working with Symfony’s Api Platform, you’ve likely come across the concept of “not filtered duration.” It’s a powerful tool for building robust and efficient APIs, but it can be tricky to grasp, especially for those new to the framework. In this article, we’ll delve into the world of not filtered duration, exploring what it is, how it works, and most importantly, how to master it to take your API to the next level.

What is Not Filtered Duration?

In Api Platform, filtering is a crucial aspect of querying data. By default, Api Platform filters out results based on the duration of a specific action. For instance, when retrieving a list of orders, Api Platform might filter out orders that are older than a certain duration. This is known as “filtered duration.”

Not filtered duration, on the other hand, is a clever way to bypass this filtering mechanism. By setting a specific configuration, you can instruct Api Platform to ignore the duration filter and return all results, regardless of their age. Sounds simple, but it’s a game-changer for certain use cases.

Why Would You Want to Use Not Filtered Duration?

There are several scenarios where not filtered duration comes in handy:

• Archiving old data: Imagine you have a database filled with historical data that’s still valuable for analytics or compliance purposes. By using not filtered duration, you can retrieve this data without worrying about Api Platform’s default filtering mechanism.

• Debugging and testing: During development, it’s essential to test your API thoroughly. Not filtered duration allows you to retrieve all data, regardless of its age, making it easier to identify issues and debug your code.

• Custom filtering logic: Sometimes, you need more control over how your data is filtered. By bypassing Api Platform’s default filtering, you can implement custom filtering logic that suits your specific use case.

Configuring Not Filtered Duration in Api Platform

To enable not filtered duration, you’ll need to configure Api Platform’s `durationassin` parameter. This parameter is part of the `api_platform` configuration in your `config.yaml` file.

api_platform:
  mapping:
    paths: ['%kernel.project_dir%/config/api_platform']
  durationassin:
    enabled: true
    not_filtered: true

In this example, we’re enabling the `durationassin` feature and setting `not_filtered` to `true`. This tells Api Platform to ignore the default filtering mechanism and return all results, regardless of their duration.

Using Not Filtered Duration in Your API Endpoints

Now that you’ve configured not filtered duration, it’s time to use it in your API endpoints. Let’s create a simple example using Api Platform’s built-in `GET /orders` endpoint.

Assuming you have an `Order` entity with a `createdAt` property, you can use the following code to retrieve all orders, ignoring the duration filter:

use App\Entity\Order;
use ApiPlatform\Core\Annotation\ApiResource;

/**
 * @ApiResource(
 *     collectionOperations={
 *         "get"={
 *             "path"="/orders",
 *             "method"="GET",
 *             "durationassin"={"not_filtered"=true}
 *         }
 *     }
 * )
 */
class Order
{
    // ...
}

In this example, we’re using the `durationassin` annotation to enable not filtered duration for the `GET /orders` endpoint. This will retrieve all orders, regardless of their creation date.

Advanced Use Cases: Using Not Filtered Duration with Other Api Platform Features

Not filtered duration can be combined with other Api Platform features to create powerful and flexible APIs. Let’s explore a few advanced use cases:

Using Not Filtered Duration with Api Platform’s Filtering System

Api Platform’s filtering system allows you to create custom filters for your API endpoints. By combining not filtered duration with filtering, you can create highly customized queries that ignore the default filtering mechanism.

use App\Entity\Order;
use ApiPlatform\Core\Annotation\ApiResource;
use ApiPlatform\Core\Annotation\ApiFilter;

/**
 * @ApiResource(
 *     collectionOperations={
 *         "get"={
 *             "path"="/orders",
 *             "method"="GET",
 *             "durationassin"={"not_filtered"=true},
 *             "filters"={"order_filter"}
 *         }
 *     }
 * )
 * @ApiFilter(OrderFilter::class, arguments={"order.property"="createdAt"})
 */
class Order
{
    // ...
}

In this example, we’re using the `OrderFilter` class to filter orders based on the `createdAt` property. By setting `not_filtered` to `true`, we’re ignoring the default filtering mechanism and retrieving all orders, regardless of their creation date.

Using Not Filtered Duration with Api Platform’s Pagination System

Api Platform’s pagination system allows you to limit the number of results returned by your API endpoints. By combining not filtered duration with pagination, you can create APIs that return large datasets while ignoring the default filtering mechanism.

use App\Entity\Order;
use ApiPlatform\Core\Annotation\ApiResource;
use ApiPlatform\Core\Annotation\ApiPagination;

/**
 * @ApiResource(
 *     collectionOperations={
 *         "get"={
 *             "path"="/orders",
 *             "method"="GET",
 *             "durationassin"={"not_filtered"=true},
 *             "pagination"={"enabled"=true, "items_per_page"=100}
 *         }
 *     }
 * )
 */
class Order
{
    // ...
}

In this example, we’re enabling pagination for the `GET /orders` endpoint and setting the `items_per_page` parameter to 100. By setting `not_filtered` to `true`, we’re ignoring the default filtering mechanism and retrieving all orders, regardless of their creation date.

Conclusion

In this comprehensive guide, we’ve explored the world of not filtered duration in Symfony’s Api Platform. From understanding the concept to configuring and using it in your API endpoints, we’ve covered it all.
