Overview

The JSON Import module allows you to import Drupal content types, paragraph types, and content from JSON configuration via an admin form or drush command. This module is forked from dcloud_import but focuses specifically on JSON-based imports without API functionality.

Features

• Admin form interface for importing JSON configurations
• Drush command for command-line imports
• Support for content types, paragraph types, fields, and content
• Preview mode to see what would be imported
• Comprehensive validation of JSON structure

Installation

1. Place the module in modules/custom/json_import
2. Enable the module: drush en json_import

Usage

Admin Interface

Navigate to Configuration → Content authoring → JSON Content Import (/admin/config/content/json-import)

The form provides:

• JSON input field with validation
• Example JSON configuration
• Preview mode option

Drush Command

Import from command line:

# Import from a JSON file
drush json_import:import /path/to/config.json

# Preview what would be imported
drush json_import:import /path/to/config.json --preview

# Using alias
drush ji:import /path/to/config.json

JSON Structure

The module expects JSON with model and/or content arrays:

{
  "model": [
    {
      "bundle": "event",
      "description": "Content type for events",
      "label": "Event",
      "body": true,
      "fields": [
        {
          "id": "event_date",
          "label": "Event Date", 
          "type": "datetime"
        }
      ]
    }
  ],
  "content": [
    {
      "id": "event1",
      "type": "node.event",
      "values": {
        "title": "Sample Event",
        "event_date": "2024-03-15T09:00:00"
      }
    }
