Views Config Field

A Drupal module that provides a Views field plugin to display configuration values from Drupal's configuration system.

Overview

The Views Config Field module allows site builders to add any Drupal configuration value as a field in Views. This is particularly useful for displaying site settings, module configuration, or any other configurable values directly in Views without requiring custom code.

Features

• Configuration Field Plugin: Adds a new field type to Views that can display any configuration value
• Nested Key Support: Supports dot notation for accessing nested configuration values (e.g., site.name or user.settings.anonymous)
• Flexible Configuration: Works with any Drupal configuration object
• Cache Integration: Properly integrates with Drupal's caching system
• Type Safety: Built with PHP 8.1+ features and strict typing

Requirements

• Drupal 10.3 or higher
• PHP 8.1 or higher

Installation

1. Download and install the module using Composer:

   composer require drupal/views_config_field

2. Enable the module:

   drush en views_config_field

   Or install via the Drupal admin interface at /admin/modules.

Usage

Adding a Config Field to a View

1. Edit any View that supports fields
2. Add a new field
3. Select "Config value" from the field list
4. Configure the field:
   • Configuration name: The configuration object to load (e.g., system.site, user.settings)
   • Configuration key: The property to display (e.g., name, email, anonymous)

Examples

Display Site Name

• Configuration name: system.site
• Configuration key: name

Display Site Email

• Configuration name: system.site
• Configuration key: mail

Display Anonymous User Name

• Configuration name: user.settings
• Configuration key: anonymous

Display Nested Configuration Values

For nested configuration values, use dot notation:

• Configuration name: system.performance
• Configuration key: css.preprocess

Advanced Usage

# my_module.settings.yml
api:
  endpoints:
    primary: "https://api.example.com"
    fallback: "https://backup.example.com"
  timeout: 30

You can access these values using:

• api.endpoints.primary for the primary endpoint URL
• api.endpoints.fallback for the fallback endpoint URL
• api.timeout for the timeout value

Configuration

The module provides a single Views field plugin with the following configuration options:

• Configuration name (required): The name of the configuration object to load
• Configuration key (required): The key or nested key path to the value to display

API

Views Field Plugin

The module provides a single Views field plugin:

• Plugin ID: views_config_field
• Class: Drupal\views_config_field\Plugin\views\field\ViewsConfigField

Hook Implementation

The module implements hook_views_data_alter() to register the field plugin with Views.

Caching

The field plugin properly implements CacheableDependencyInterface and uses CacheableDependencyTrait to ensure that Views containing config fields are properly invalidated when the underlying configuration changes.
