How can I implement content versioning for tracking and managing the collaborative editing platform?

In the context of Salesforce, you can implement content versioning for a collaborative document editing platform by using these steps:-

Database schema for document version

You can design a database schema that can include a table for scoring document versions. Each version should have the attributes such as version numbers, timestamps, author, and the content of the document:-

CREATE TABLE DocumentVersions (
    VersionId INT AUTO_INCREMENT PRIMARY KEY,
    DocumentId INT,
    VersionNumber INT,
    Timestamp DATETIME,
    AuthorId INT,
    Content TEXT,
    FOREIGN KEY (DocumentId) REFERENCES Documents(DocumentId),
    FOREIGN KEY (AuthorId) REFERENCES Users(UserId)
);

API endpoint for saving document versions

You can Create an API endpoint that can allow users to save new versions of documents. The endpoint should receive the document content, author ID, and Document ID as parameters and then you can insert a new record into the table of “DocumentVersion”:-

From flask import Flask, request, jsonify
Import datetime
Import mysql.connector
App = Flask(__name__)
# Database connection
Db = mysql.connector.connect(
    Host=’localhost’,
    User=’username’,
    Password=’password’,
    Database=’your_database’
)
Cursor = db.cursor()
@app.route(‘/save_version’, methods=[‘POST’])
Def save_version():
    Data = request.json
    Document_id = data[‘document_id’]
    Content = data[‘content’]
    Author_id = data[‘author_id’]
    Timestamp = datetime.datetime.now()
    # Insert new version into the database
    Insert_query = “INSERT INTO DocumentVersions (DocumentId, VersionNumber, Timestamp, AuthorId, Content) “ 
                   “VALUES (%s, (SELECT COALESCE(MAX(VersionNumber), 0) + 1 FROM DocumentVersions WHERE DocumentId = %s), %s, %s, %s)”
    Cursor.execute(insert_query, (document_id, document_id, timestamp, author_id, content))
    Db.commit()
    Return jsonify({‘message’: ‘Version saved successfully’}), 200
If __name__ == ‘__main__’:
    App.run(debug=True)

Retrieving and displaying document versions

You can create another API endpoint to retrieve and display document versions. The users can view the history of changes made to a document and revert to a previous version if needed:-

@app.route(‘/get_versions/’, methods=[‘GET’])
Def get_versions(document_id):
    # Fetch all versions of the document from the database
    Select_query = “SELECT VersionId, VersionNumber, Timestamp, AuthorId FROM DocumentVersions WHERE DocumentId = %s ORDER BY VersionNumber DESC”
    Cursor.execute(select_query, (document_id,))
    Versions = cursor.fetchall()
    Version_data = []
    For version in versions:
        Version_data.append({
            ‘VersionId’: version[0],
            ‘VersionNumber’: version[1],
            ‘Timestamp’: version[2].strftime(‘%Y-%m-%d %H:%M:%S’),
            ‘AuthorId’: version[3]
        })
    Return jsonify(version_data), 200
