Webmapp Laravel wm-package

This is where your description should go. Limit it to a paragraph or two. Consider adding a small example.

Installation

You can install the package via composer:

You can publish and run the migrations with:

You can publish the config file with :

Usage

You can use Services with:

ServiceClass::make()->method() eg: GeometryComputationService::make()->convertToPoint($model)

You can use Models with or without extending them: class MyEcTrackModel extends Wm\WmPackage\Models\EcTrack {...}

You can use Nova resources extending them: class MyEcTrackNovaResource extends Wm\WmPackage\Nova\EcTrack {...}

You can use all package APIs with related controllers, see them with php artisan route:list

You can use all clients with dependency injection or with other instanciation methods: app( Wm\WmPackage\Http\Clients\DemClient::class)->getTechData($geojson);

Update

You can update the package via composer:

or updating it as submodule

Developing

To use docker containers you need to run docker compose up -d and enter inside with docker compose exec -it php bash or directly docker compose exec -it php composer test (check permissions on files before run it, if you have problems use the -u param on exec command with the id of the user who owns project files and directories, to check your current user id you can use the command id).

Docker has the following containers:

• php
• postgres
• redis
• elasticsearch

You can use them with testbench to run a complete Laravel instance with this package (see testing section for more details). Eg, you can use tesbench to run artisan commands: ./vendor/bin/testbench migrate

We use conventional commits for commit's messages (https://www.conventionalcommits.org/en/v1.0.0/). Create a feature/fix branch from main then ask a PR to merge it into develop branch.

On a laravel instance

If you need this package on full laravel instance you have to add this repository as submodule in the root path of Laravel with git submodule add {git repo}, then add a new composer path repository in the laravel composer.json file:

at last you can install the package with compose require wm/wm-package

JWT

JWT will be installed automatically as a dependency. Users only need to configure the JWT environment variables in the .env file using the command php artisan jwt:secret.

The JWT package is managed as a dependency of wm-package and does not need to be installed separately in the main application.

Elasticsearch

elasticsearch mapping and settings: config/wm-elasticsearch.php

elasticsearch controller: src/Http/Controllers/Api/ElasticsearchController.php

Geohub Import

This package provides an Artisan command to import data from Geohub. To ensure data integrity and correctly process all relationships, the import process must start from an app entity. The command will then import all related data in a cascading manner.

The import architecture is structured around a pattern of services, jobs, and a central configuration, with an Artisan command as the entry point.

Architecture Overview

The main components are:

1. CLI Command (WmImportFromGeohubCommand): The entry point to initiate imports.
2. Services (GeohubImportService, EcMediaImportService): Handle the core business logic, data transformation, and orchestration.
3. Jobs (e.g., ImportAppJob, ImportEcTrackJob): Perform specific import operations for different entities in the background.
4. Configuration (config/wm-geohub-import.php): Contains mappings, database connections for Geohub, and other settings that define how the import process behaves.

Command Usage

The main command is wm:import-from-geohub.

1. Import a specific application and its related data: This is the standard way to import a complete set of data related to a specific application.

   Replace <geohub_app_id> with the ID of the application in Geohub.

2. Import all applications and their related data: If no model or ID is specified (or if app is specified without an ID), the command will import all app entities from Geohub, subsequently triggering the import for all their related data.

   Or:

Import Process Deep Dive

The import process is orchestrated by GeohubImportService.

1. GeohubImportService - The Core Orchestrator

This service is central to the import system and manages:

• Geohub Database Connection: Connects to the Geohub source database using credentials and settings defined in config/wm-geohub-import.php.

• Orchestration: Coordinates the import of different entities. While the primary flow starts with an app and cascades, the service internally might respect a specific order for fetching or processing, defined by constants like MODEL_IMPORT_ORDER if applicable for broad imports.

• Data Transformation: Converts data from Geohub's format to the local application's format, often leveraging the DataTransformer utility.
• Relationship Management: Ensures that associations between entities are correctly established and maintained during the import.

2. Data Mapping and Configuration (config/wm-geohub-import.php)

This crucial configuration file defines how different entities are handled. For each entity type, it specifies:

• namespace: The local Eloquent model's namespace.
• job: The dedicated import Job class for that entity.
• geohub_table: The source table name in the Geohub database.
• identifier: The field used as a unique identifier (e.g., custom_properties->geohub_id).
• fields: Mapping of source fields to target fields.
• properties: Mapping for JSON properties.
• relations: Definitions for handling relationships with other entities.

Example: ec_media configuration snippet:

3. Job Hierarchy and Structure

Import jobs are organized hierarchically to share common logic:

• BaseImportJob: The base class for all import jobs. It manages the general import workflow (fetch, transform, import, process dependencies) and provides common data transformation utilities.
• BaseEcImportJob: Extends BaseImportJob specifically for "EC" entities (e.g., EcTrack, EcPoi). It handles common tasks like converting 2D geometries from Geohub to 3D and setting default values for missing geometries.
• Specific Jobs (e.g., ImportAppJob, ImportEcPoiJob, ImportEcTrackJob, ImportLayerJob, ImportTaxonomyJob and its derivatives): Implement logic tailored to each entity type.

Each job typically follows a structure with these key methods:

• fetchData(): Retrieves raw data from the Geohub database for the specific entity.
• transformData(): Converts the fetched data into the format required by the local models, often using DataTransformer.
• importData(): Creates or updates the entity in the local database.
• processDependencies(): Handles the import or linking of related entities.

4. Data Transformation (DataTransformer)

The DataTransformer class is a utility responsible for converting data types and structures.

• Key Features:
  • Format Conversion: Transforms data between JSON, arrays, booleans, dates, etc.
  • Normalization: Standardizes incoming data.
  • Multilingual Data Handling: Converts JSON strings containing translations (e.g., {"it":"Nome","en":"Name"}) into associative arrays for translatable model attributes.
  • Implicit Validation: Manages null or empty values appropriately.
• Core Methods:
  • jsonToArray(): Converts JSON strings to PHP arrays.
  • stringToBoolean(): Converts string representations of booleans to actual boolean values.
  • stringToDate() / dateToString(): Handles date conversions.
  • geojsonToGeometry(): Processes GeoJSON data into geometry objects.
• Integration: DataTransformer methods are typically invoked from the mapping configuration within config/wm-geohub-import.php or directly within job transformation logic.

Example: Transforming a translatable name field: Mapping in wm-geohub-import.php:

If Geohub name is {"it":"Sentiero del Monte","en":"Mountain Trail"}, it's transformed to ['it' => 'Sentiero del Monte', 'en' => 'Mountain Trail'].

5. Special Case: Media Import (ImportEcMediaJob & EcMediaImportService)

Media import (images, files) involves ImportEcMediaJob and potentially EcMediaImportService for more complex scenarios:

1. Data Retrieval: Fetches media metadata from Geohub.
2. Relationship Identification: Determines which local entity the media is associated with.
3. Download & Upload: Downloads the actual file from Geohub's storage and uploads it to the configured local storage (e.g., AWS S3 via Spatie Media Library).
4. Metadata Storage: Saves relevant metadata, including custom properties.

6. Queues, Batching, and Error Handling

• Asynchronous Processing: All import operations are dispatched as jobs to a configurable queue (default: geohub-import) for background processing, which is essential for handling large datasets.
• Batching: Jobs are often grouped into batches. Batches can be configured with failure tolerance, allowing the overall import to continue even if some individual jobs fail.
• Logging: Comprehensive logging is implemented. Operations are logged to a dedicated channel (configurable via wm-geohub-import.import_log_channel, e.g., storage/logs/wm-package-failed-jobs.log).
• Exceptions: Specific exceptions are used to provide detailed error messages, aiding in debugging.

7. Performance Considerations

The system is designed to handle potentially large volumes of data:

• Queues & Jobs: Laravel's queue system distributes the workload.
• Batching: Efficiently processes groups of jobs.
• Horizon: Laravel Horizon can be used to monitor and manage the queues.

Summary of Import Flow

When an import is initiated (typically for an app):

1. WmImportFromGeohubCommand delegates to GeohubImportService.
2. GeohubImportService connects to the Geohub DB and identifies entities to import (starting with the specified app or all apps).
3. It creates and dispatches a batch of jobs (e.g., ImportAppJob).
4. Each job in the sequence: a. Fetches data from Geohub (fetchData). b. Transforms data using mappings and DataTransformer (transformData). c. Creates or updates the entity in the local database (importData). d. Queues further jobs for dependent entities (processDependencies).
5. Media imports handle file downloads/uploads separately.
6. The process is logged, and errors are managed to ensure robustness.

This architecture provides a modular, robust, configurable, and scalable process for synchronizing data from Geohub.

Testing

These tools are used to test the stand alone instance of wm-package: https://packages.tools/

Execute these commands to runs tests:

./vendor/bin/testbench vendor:publish --tag="wm-package-migrations" ./vendor/bin/testbench migrate It migrates workbench tables on a postgres database.

composer test To run tests.

If an evaluation of testbench env I suggest to use the config() function (eg: config('database.connections')) with the testbench implementation of tinker ./vendor/bin/testbench tinker, it is also useful to understand which things are loaded on the testbench env.

Testbench reference: https://packages.tools/testbench.html Workbench reference: https://packages.tools/workbench.html

Also a simple php docker container is available to run tests, you can start it using docker compose up -d and enter inside with docker compose exec -it php bash or directly docker compose exec -it php composer test (check permissions on files before run it, if you have problems use the -u param on exec command with the id of the user who owns project files and directories, to check your current user id you can use the command id).
