API

from flask_wtf import FlaskForm

class DocumentUploadForm(FlaskForm):
    """
    A form for uploading documents that requires a file to be present.

    The form should:
    - Have a field named 'document' for file uploads
    - Ensure that a file is actually uploaded (not just an empty form submission)
    - Use appropriate validation to enforce file presence
    """
    pass


def process_upload(form):
    """
    Process the upload form and return the uploaded filename if validation succeeds.

        A dictionary with either:
        - {'success': True, 'filename': str} if validation passes
        - {'success': False, 'error': str} if validation fails
    """
