## Setup and Installation
|
|
|
|
1. Clone the repository:
|
|
|
|
```bash
|
|
git clone <repository-url>
|
|
cd generic-rest-api-service
|
|
```
|
|
|
|
2. Create and activate a virtual environment (optional, but recommended):
|
|
|
|
```bash
|
|
python -m venv venv
|
|
source venv/bin/activate # On Windows: venv\\Scripts\\activate
|
|
```
|
|
|
|
3. Install dependencies:
|
|
|
|
```bash
|
|
pip install -r requirements.txt
|
|
```
|
|
|
|
4. Run database migrations:
|
|
|
|
```bash
|
|
# Make sure you are in the project root directory
|
|
alembic upgrade head
|
|
|
|
# If you encounter any module import errors, you can also try:
|
|
PYTHONPATH=$PWD alembic upgrade head
|
|
```
|
|
|
|
5. Start the application:
|
|
|
|
```bash
|
|
uvicorn main:app --reload
|
|
```
|
|
|
|
The application will be available at http://127.0.0.1:8000.
|
|
|
|
## API Documentation

|
|
|
Once the application is running, you can access the automatically generated API documentation:
|
|
|
|
- Swagger UI: http://127.0.0.1:8000/docs
|
|
- ReDoc: http://127.0.0.1:8000/redoc
