In the court, a young concubine is worried about writing the IoT platform.
“Your Majesty, I recently received a task to develop an IoT platform, but I always feel that writing code is too slow. Is there any magical tool that can help me improve my efficiency?”
“Do not worry, my dear. Today I will introduce you to a capable assistant – Cursor. It is not only a smart code completion assistant but also a caring programming mentor.”
“Really? Then please demonstrate for me, Your Majesty~”
“Alright, let me help you install Cursor first. It is developed based on VS Code, has a clean interface, and is very user-friendly. After downloading, let’s create a simple IoT device management interface.”
●●●
from fastapi import FastAPI
from pydantic import BaseModel
app = FastAPI()
class Device(BaseModel):
id: str
name: str
status: bool
@app.post(“/devices/”)
async def create_device(device: Device):
return device
“Wow! Your Majesty only entered a few keywords, and Cursor automatically helped complete so much code!”
“Not only that, my dear. When you want to add new features, just write a comment in the code, and Cursor will understand your intention. Let me demonstrate how to add an interface to get the device list.”
●●●
# Add an in-memory database to store device information
devices_db = []
# Create device interface
@app.post(“/devices/”)
async def create_device(device: Device):
devices_db.append(device)
return device
# Get all device list
@app.get(“/devices/”)
async def get_devices():
return devices_db
“So amazing! Is this the legendary AI programming assistant? How can I implement the function to update device status?”
“My dear, just watch. In Cursor, we can directly describe our requirements, and it will generate the corresponding code.”
●●●
# Interface to update device status
@app.put(“/devices/{device_id}”)
async def update_device(device_id: str, device: Device):
for i, d in enumerate(devices_db):
if d.id == device_id:
devices_db[i] = device
return device
return {“error”: “Device not found”}
“I understand now! Not only does the code generate automatically, but Cursor also handles error situations automatically. What if I want to add a function for device data reporting?”
“Good! Let me show you how to add the data reporting function. We need to create a new model and interface.”
●●●
from datetime import datetime
class DeviceData(BaseModel):
device_id: str
timestamp: datetime
temperature: float
humidity: float
device_data_db = []
@app.post(“/devices/{device_id}/data”)
async def report_device_data(device_id: str, data: DeviceData):
data.device_id = device_id
device_data_db.append(data)
return data
“Awesome! Now our IoT platform has basic device management and data reporting functions. But I still have a question, how can we make the code easier to maintain?”
“You ask a good question! Cursor can not only write code but also help us refactor and optimize code. Let me show you how to organize the code more clearly.”
●●●
from typing import List
from fastapi import HTTPException
# Encapsulate database operations into a class
class DeviceRepository:
def __init__(self):
self.devices = []
self.device_data = []
def add_device(self, device: Device) -> Device:
self.devices.append(device)
return device
def get_devices(self) -> List[Device]:
return self.devices
def update_device(self, device_id: str, device: Device) -> Device:
for i, d in enumerate(self.devices):
if d.id == device_id:
self.devices[i] = device
return device
raise HTTPException(status_code=404, detail=”Device not found”)
device_repo = DeviceRepository()
“I see! Cursor not only helps us write code but also teaches us better programming practices.”
“Indeed. Cursor is like a programming assistant always on standby, which not only improves development efficiency but also helps us learn and grow. My dear, you can practice more and believe you will soon master this magical tool.”
“Thank you for your guidance, Your Majesty! I will study Cursor diligently and strive to complete the development task of the IoT platform as soon as possible!”
Through this exchange, we not only learned the basic usage of Cursor but also how to quickly develop the core functions of an IoT platform using it. Remember, Cursor is not just a tool, but a good partner on your path to growth.
Would you like me to explain or break down any of the code examples?
