Foolproof Guide to Developing Smart Reports in One Day

Travel back to the Tang Dynasty and see Your Majesty lead the beloved concubine through the wonderful world of Cursor intelligent development~

Concubine: Your Majesty, I’ve just received a request to develop a smart report, and I need to complete it in one day. I’m so anxious!

Your Majesty: Don’t worry, today I will teach you how to use the so-called “AI programming assistant” Cursor, which will help you easily tackle this challenge.

Concubine: Cursor? What kind of magical tool is that?

Your Majesty: This is a powerful editor based on VS Code, built with the GPT-4 large model. It’s like having a programming mentor online at all times, helping you write code, refactor code, explain code, and even discuss technical issues with you.

Concubine: Wow! That sounds amazing! How do I get started?

Your Majesty: Let me demonstrate for you. First, we need to download and install Cursor by visiting the official website cursor.sh. Once installed, let’s start creating a new project.

Concubine: Your Majesty, I’m ready! What should I do next?

Your Majesty: Let’s first create a basic report project structure using Cursor. Press Cmd/Ctrl + L to open the AI command panel and enter:

Please help me create a basic directory structure for a smart report project, including a front-end and back-end separation.

In an instant, Cursor provided the recommended directory structure:

smart-report/
├── frontend/
│   ├── src/
│   │   ├── components/
│   │   ├── pages/
│   │   ├── utils/
│   │   └── App.js
│   ├── package.json
│   └── README.md
└── backend/
    ├── src/
    │   ├── controllers/
    │   ├── models/
    │   ├── routes/
    │   └── app.js
    ├── package.json
    └── README.md

Concubine: Wow! That was so fast! How do we implement the specific functions of the report?

Your Majesty: Don’t rush, let’s first implement the back-end API. In Cursor, we can directly describe the requirements, and it will help us generate the code. For example, to create a data statistics interface:

// backend/src/controllers/reportController.js
const generateReport = async (req, res) => {
    try {
        const { startDate, endDate, reportType } = req.query;
        // Get statistical data based on query parameters
        const reportData = await Report.aggregate([
            {
                $match: {
                    createTime: {
                        $gte: new Date(startDate),
                        $lte: new Date(endDate)
                    }
                }
            },
            {
                $group: {
                    _id: "$category",
                    total: { $sum: "$amount" }
                }
            }
        ]);
        res.json({
            success: true,
            data: reportData
        });
    } catch (error) {
        res.status(500).json({
            success: false,
            message: error.message
        });
    }
};

Concubine: That’s amazing! What about displaying it on the front end?

Your Majesty: We can quickly generate a report component based on React using Cursor. Just describe the requirements in the AI command panel:

// frontend/src/components/ReportChart.jsx
import React, { useState, useEffect } from 'react';
import { Line } from '@antd/charts';
const ReportChart = ({ reportData }) => {
    const [chartConfig, setChartConfig] = useState({
        data: [],
        xField: 'date',
        yField: 'value',
        seriesField: 'category',
        smooth: true,
    });
    useEffect(() => {
        if (reportData) {
            setChartConfig(prev => ({
                ...prev,
                data: reportData
            }));
        }
    }, [reportData]);
    return (
        <div classname="report-chart">
            <line {...chartconfig}=""></line>
        </div>
    );
};
export default ReportChart;

Concubine: That’s fantastic! But I still don’t quite understand some of this code. Can Cursor explain it?

Your Majesty: Of course. Just select the code, press Cmd/Ctrl + K, and then enter “Please explain the function of this code”.

Concubine: Oh! I see now. What if I want to add new features or modify the code?

Your Majesty: The best part of Cursor is that it understands your intent. For example, if you want to add a PDF export feature, just enter a natural language description in the command panel:

// frontend/src/utils/exportPDF.js
import jsPDF from 'jspdf';
import 'jspdf-autotable';
export const exportToPDF = (reportData) => {
    const doc = new jsPDF();
    doc.text('Smart Report Statistics', 14, 15);
    const tableData = reportData.map(item => [
        item.category,
        item.total.toFixed(2)
    ]);
    doc.autoTable({
        head: [['Category', 'Amount']],
        body: tableData,
        startY: 20
    });
    doc.save('report.pdf');
};

Concubine: Your Majesty, this is incredible! I feel like my development efficiency has increased many times!

Your Majesty: That’s right, Cursor is that powerful. It can help you not only write code but also:

• Automatically complete code

• Real-time code review

• Intelligent refactoring suggestions

• Answer technical questions

• Generate unit tests

Concubine: Now that I’ve learned this, I won’t be afraid when similar requests come up again!

Your Majesty: Exactly. Remember the key shortcuts for using Cursor:

• Cmd/Ctrl + L: Open AI command panel

• Cmd/Ctrl + K: Get code explanation

• Cmd/Ctrl + I: Inline code completion

• Cmd/Ctrl + Shift + L: Open chat window

Concubine: I really learned a lot! Thank you, Your Majesty!

Your Majesty: You’re welcome, Concubine. Your after-class task: Try using Cursor to add a data filtering feature to make the report display more flexible. Remember, if you encounter problems, just ask Cursor; it will be your best programming assistant.

Concubine: Yes, Your Majesty! I will practice right away. With Cursor’s help, I believe I will complete it soon!
