velt-py 0.1.6

Python SDK for integrating Velt comments, reactions, attachments, and user management into Django applications

Velt Python SDK

A Python SDK for integrating Velt comments, reactions, attachments, and user management into Django applications with MongoDB backend.

Installation

pip install velt-py

Requirements

• Python 3.8+
• Django 4.2.26+
• MongoDB (Percona Server or MongoDB Atlas)
• PyMongo 4.6.3
• MongoEngine 0.27.0

Quick Start

1. Initialize the SDK

from velt_py import VeltSDK

# Initialize SDK with your MongoDB configuration
sdk = VeltSDK.initialize(config={
    'database': {
        'host': 'localhost:27017',
        'username': 'your-username',
        'password': 'your-password',
        'auth_database': 'admin',
        'database_name': 'velt-integration'  # Your database name
    },
    'apiKey': 'your-velt-api-key',  # Optional: can use VELT_API_KEY env var
    'authToken': 'your-velt-auth-token'  # Optional: can use VELT_AUTH_TOKEN env var
})

2. Use Services

The SDK supports different backends. For self-hosted installations, use the selfHosting backend:

# Comments
result = sdk.selfHosting.comments.getComments(
    organizationId='org-123',
    commentAnnotationIds=['ann-1', 'ann-2'],
    documentIds=['doc-1']
)

sdk.selfHosting.comments.saveComments(
    organizationId='org-123',
    commentAnnotation={
        'ann-1': {
            'comments': {'comment-1': {'commentId': 'comment-1', 'commentText': 'Hello'}},
            'metadata': {}
        }
    },
    documentId='doc-1'
)

sdk.selfHosting.comments.deleteComment(
    organizationId='org-123',
    commentAnnotationId='ann-1'
)

# Reactions
result = sdk.selfHosting.reactions.getReactions(
    organizationId='org-123',
    reactionAnnotationIds=['reaction-1'],
    documentIds=['doc-1']
)

sdk.selfHosting.reactions.saveReactions(
    organizationId='org-123',
    reactionAnnotation={
        'reaction-1': {
            'icon': '👍',
            'metadata': {}
        }
    },
    documentId='doc-1'
)

# Attachments
result = sdk.selfHosting.attachments.getAttachment(
    organizationId='org-123',
    attachmentId=12345
)

sdk.selfHosting.attachments.saveAttachment(
    organizationId='org-123',
    attachment={
        'attachmentId': 12345,
        'name': 'document.pdf',
        'mimeType': 'application/pdf',
        'base64Data': '...',
        'size': 1024
    },
    documentId='doc-1'
)

# Users
result = sdk.selfHosting.users.getUsers(
    organizationId='org-123',
    userIds=['user-1', 'user-2']
)

sdk.selfHosting.users.saveUser(
    organizationId='org-123',
    user={
        'userId': 'user-1',
        'name': 'John Doe',
        'email': '[e-mail]',
        'photoUrl': 'https://example.com/photo.jpg'
    }
)

# Token
result = sdk.selfHosting.token.getToken(
    organizationId='org-123',
    userId='user-1',
    email='[e-mail]',
    isAdmin=False
)
token = result['data']['token']

Response Format

All service methods return a standardized response format:

Success Response

{
    'success': True,
    'data': {
        # Service-specific data
    }
}

Error Response

{
    'success': False,
    'error': 'Human-readable error message',
    'errorCode': 'ERROR_CODE'  # Optional
}

Data Isolation

All methods require organizationId as the first parameter to ensure data isolation between organizations. The SDK automatically filters all queries by organizationId.

Configuration

Database Configuration

The SDK accepts database configuration in the following format:

config = {
    'database': {
        'host': 'localhost:27017',  # or 'mongodb://...' connection string
        'username': 'your-username',
        'password': 'your-password',
        'auth_database': 'admin',
        'database_name': 'velt-integration'  # Your database name,
        # Optional: override with full connection string
        # 'connection_string': 'mongodb://...'
    }
}

Environment Variables

You can also use environment variables for API credentials:

• VELT_API_KEY - Velt API key
• VELT_AUTH_TOKEN - Velt auth token

Error Handling

The SDK uses custom exceptions:

• VeltSDKError - Base exception
• VeltDatabaseError - Database-related errors
• VeltValidationError - Validation errors
• VeltTokenError - Token-related errors

from velt_py import VeltSDKError, VeltDatabaseError

try:
    result = sdk.selfHosting.comments.getComments(organizationId='org-123')
except VeltDatabaseError as e:
    print(f"Database error: {e}")
except VeltSDKError as e:
    print(f"SDK error: {e}")
