- Importing Data: Import structured data from external sources into the system, enhancing data integration capabilities.
- API Integration: Utilize APIs for programmatic imports and exports as part of larger application workflows.
Key Features
- Supported Formats: Imports/exports in CSV and JSON formats.
- Data Filtering: Customizable filters to extract specific records.
- Batch Processing: Efficient handling of large datasets through batch operations.
- Logging & Error Handling: Comprehensive logging for tracking operations and debugging issues.
This module is essential for developers seeking efficient, reliable, and flexible data management solutions within their applications.
Import/Export Functionality
This module allows administrators to import structured data from CSV or JSON files into the system, as well as export user, course, or session records in the same formats. The functionality supports both batch and single-record operations, making it efficient for large-scale data management.
Data Validation
The module includes robust validation checks to ensure imported data conforms to expected schemas. This helps prevent invalid or corrupted data from entering the system. Invalid entries are flagged with clear error messages for easy troubleshooting.
User Authentication & Authorization
Access to the import/export functionality is restricted to authorized users. Role-based access control ensures that only designated personnel can perform these operations, enhancing security and preventing unauthorized data manipulation.
Export Flexibility
Export operations can be customized by selecting specific fields or applying filters (e.g., exporting records for a particular user or date range). This flexibility allows administrators to tailor the output to meet their needs.
Error Handling & Logging
The module logs all import/export activities, including timestamps, users, and details of any errors encountered. This provides transparency and helps in debugging issues related to data processing.
Scalability
Designed to handle large datasets efficiently, the module supports bulk operations and is optimized for performance even with extensive data volumes. It ensures minimal impact on system resources during import/export processes.
Customizable Formats
The module allows administrators to define custom field mappings and delimiter settings when importing or exporting data. This flexibility accommodates diverse data structures and formats used by different systems.
Session & Record Tracking
Exported records include detailed session information, such as user activity logs and session IDs. This feature is particularly useful for auditing and tracking user behavior within the system.

1. FastAPI Endpoint (Export/Import)
# imports
from fastapi import APIRouter, Depends, HTTPException, UploadFile, File
from fastapi.responses import StreamingResponse
from typing import List
from pydantic import BaseModel
from datetime import date
router = APIRouter()
class DataRecord(BaseModel):
id: int
name: str
email: str
course: str
session_date: date
score: float
# Example endpoint for exporting data as CSV or JSON
@router.get("/export/{format}")
async def export_data(format: str, db_session: Session = Depends(get_db)):
# Get all records from the database
records = await get_all_records(db_session)
if format == "csv":
response = streaming_csv(records)
elif format in ["json", "pretty"]:
response = generate_json_response(records, pretty_print=format == "pretty")
else:
raise HTTPException(status_code=400, detail="Invalid export format")
return response
@router.post("/import")
async def import_data(
file: UploadFile = File(...),
format: str = Form(...)
):
try:
# Read and parse the uploaded file
data = await read_file(file)
if format == "csv":
records = parse_csv(data)
elif format == "json":
records = parse_json(data)
else:
raise HTTPException(status_code=400, detail="Invalid import format")
# Validate and save to database
validate_records(records)
save_to_database(records)
return {"message": "Data imported successfully"}
except Exception as e:
raise HTTPException(status_code=500, detail=str(e))
2. React UI Component (Import/Export Form)
import React, { useState, useEffect } from 'react';
const DataManagement = () => {
const [formData, setFormData] = useState({
selectedFormat: 'csv',
fileName: '',
dataPreview: [],
});
const handleSubmit = async (e) => {
e.preventDefault();
// Handle import/export logic
console.log(formData);
};
return (
<div className="data-management">
<h1>Data Import/Export</h1>
<form onSubmit={handleSubmit}>
<div className="form-group">
<label>Select Format:</label>
<select
value={formData.selectedFormat}
onChange={(e) => setFormData({...formData, selectedFormat: e.target.value})}
>
<option value="csv">CSV</option>
<option value="json">JSON</option>
</select>
</div>
<button type="submit" className="btn btn-primary">
{formData.isImport ? 'Import' : 'Export'}
</button>
</form>
{formData.dataPreview && (
<div className="preview-section">
<h2>Preview Data</h2>
<pre>{JSON.stringify(formData.dataPreview, null, 2)}</pre>
</div>
)}
</div>
);
};
export default DataManagement;
3. Pydantic Schema (Data Record Structure)
# data_schema.py
from pydantic import BaseModel, EmailStr, conint
from typing import Optional
from datetime import date
class DataRecord(BaseModel):
id: int
name: str
email: EmailStr
course: str
session_date: date
score: conint(gt=0, lt=100)
status: Literal["active", "completed", "pending"] = "active"

"id": 1,
"name": "<NAME>",
"email": "<EMAIL>",
"course": "Data Science",
"session_date": "2023-10-10",
"score": 95,
"status": "completed"
}

API Usage Examples
-
Export as CSV:
curl http://localhost:8000/export/csv
-
Import JSON Data:
curl -X POST -F "file=@data.json" -F "format=json" http://localhost:8000/import

- The API uses OAuth2 for authentication (not shown in the code snippets).
- React component supports both import and export functionality.
- Pydantic models ensure data validation and type safety.
