We define a SQLAlchemy model `LocalGovernment` with columns for `id`, `name`, and `county`. +2. We create a Pydantic schema `LocalGovernmentSchema` to validate the incoming data from the API request. +3. We define a FastAPI endpoint `@app.post('/local_govt')` that accepts a `LocalGovernmentSchema` object as input. +4. Inside the endpoint function, we create a SQLAlchemy session and try to add a new `LocalGovernment` object to the database using the data from the input schema. +5. If the operation is successful, we commit the changes and return a success message. +6. If an exception occurs, we roll back the transaction and raise an HTTP exception with a 500 status code and the error message. +7. Finally, we close the SQLAlchemy session. + +To use this endpoint, you can send a POST request to `/local_govt` with a JSON payload containing the `name` and `county` fields, like this: + +``` +POST /local_govt +Content-Type: application/json + +{ + "name": "Nairobi City County", + "county": "Nairobi" +} +``` + +This will create a new entry in the `local_governments` table with the provided name and county. \ No newline at end of file
