含代码

好的，下面我会给你提供一个基于Django框架的个人记账管理系统的示例代码，不过由于篇幅限制，我只能提供部分代码，希望对你有所帮助：

1. models.py

from django.db import models
from django.contrib.auth.models import User

class Category(models.Model):
    name = models.CharField(max_length=100)

class Record(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    category = models.ForeignKey(Category, on_delete=models.CASCADE)
    amount = models.DecimalField(max_digits=10, decimal_places=2)
    time = models.DateTimeField(auto_now_add=True)

    @staticmethod
    def get_total_amount(user_id):
        return Record.objects.filter(user_id=user_id).aggregate(models.Sum('amount'))['amount__sum']

2. views.py

from django.shortcuts import render, redirect
from django.contrib.auth.decorators import login_required
from .models import Record, Category

@login_required
def index(request):
    user_id = request.user.id
    total_amount = Record.get_total_amount(user_id)
    records = Record.objects.filter(user_id=user_id).order_by('-time')
    categories = Category.objects.all()

    return render(request, 'index.html', {
        'total_amount': total_amount,
        'records': records,
        'categories': categories
    })

@login_required
def add_record(request):
    if request.method == 'POST':
        category_id = request.POST['category']
        amount = float(request.POST['amount'])
        category = Category.objects.get(id=category_id)
        record = Record(user=request.user, category=category, amount=amount)
        record.save()

    return redirect('index')

3. templates/index.html

{% extends 'base.html' %}

{% block content %}
<h1>Welcome {{ request.user.username }}</h1>

<div>
    <p>Total amount: {{ total_amount }}</p>
    <p>
        <a href="{% url 'add_record' %}">Add Record</a>
    </p>
</div>

<div>
    <table>
        <thead>
            <tr>
                <th>Time</th>
                <th>Category</th>
                <th>Amount</th>
            </tr>
        </thead>
        <tbody>
            {% for record in records %}
            <tr>
                <td>{{ record.time }}</td>
                <td>{{ record.category.name }}</td>
                <td>{{ record.amount }}</td>
            </tr>
            {% endfor %}
        </tbody>
    </table>
</div>

<div>
    <form method="post" action="{% url 'add_record' %}">
        {% csrf_token %}
        <label for="category">Category:</label>
        <select name="category" id="category">
            {% for category in categories %}
            <option value="{{ category.id }}">{{ category.name }}</option>
            {% endfor %}
        </select>
        <br>
        <label for="amount">Amount:</label>
        <input type="number" name="amount" id="amount">
        <br>
        <button type="submit">Add</button>
    </form>
</div>
{% endblock %}
