用Django1.x写一个考试系统

好的，下面是一个简单的考试系统的Django项目示例。

1. 创建Django项目

首先，我们需要使用Django创建一个新项目。在终端中运行以下命令：

django-admin startproject exam_system

2. 创建应用程序

接下来，我们需要创建一个名为“exam”的应用程序。在终端中运行以下命令：

python manage.py startapp exam

3. 编写模型

在“exam/models.py”文件中，我们定义了两个模型：一个是“Quiz”，一个是“Question”，其中“Quiz”模型与“Question”模型之间是一对多的关系。

from django.db import models

class Quiz(models.Model):
    title = models.CharField(max_length=100)
    description = models.TextField()

class Question(models.Model):
    quiz = models.ForeignKey(Quiz, on_delete=models.CASCADE)
    text = models.CharField(max_length=200)
    answer = models.CharField(max_length=200)

4. 编写视图

在“exam/views.py”文件中，我们定义了三个视图函数：一个是“quiz_list”，用于显示所有的考试；一个是“quiz_detail”，用于显示某个考试的详情；另一个是“take_quiz”，用于让用户参加某个考试并提交答案。

from django.shortcuts import render, get_object_or_404
from .models import Quiz, Question

def quiz_list(request):
    quizzes = Quiz.objects.all()
    return render(request, 'exam/quiz_list.html', {'quizzes': quizzes})

def quiz_detail(request, quiz_id):
    quiz = get_object_or_404(Quiz, pk=quiz_id)
    questions = quiz.question_set.all()
    return render(request, 'exam/quiz_detail.html', {'quiz': quiz, 'questions': questions})

def take_quiz(request, quiz_id):
    quiz = get_object_or_404(Quiz, pk=quiz_id)
    questions = quiz.question_set.all()
    if request.method == 'POST':
        score = 0
        for question in questions:
            answer = request.POST.get(str(question.id))
            if answer == question.answer:
                score += 1
        return render(request, 'exam/quiz_result.html', {'score': score})
    return render(request, 'exam/take_quiz.html', {'quiz': quiz, 'questions': questions})

5. 编写URL模式

在“exam/urls.py”文件中，我们定义了三个URL模式，分别对应于上面的三个视图函数。

from django.urls import path
from . import views

app_name = 'exam'
urlpatterns = [
    path('', views.quiz_list, name='quiz_list'),
    path('<int:quiz_id>/', views.quiz_detail, name='quiz_detail'),
    path('<int:quiz_id>/take/', views.take_quiz, name='take_quiz'),
]

6. 编写模板

最后，我们需要编写模板文件来渲染视图。在“exam/templates/exam”文件夹中，我们需要创建以下四个模板文件：

- “quiz_list.html”：显示所有的考试列表
- “quiz_detail.html”：显示某个考试的详情
- “take_quiz.html”：让用户参加某个考试并提交答案
- “quiz_result.html”：显示考试结果（即用户得分）

下面是一个简单的示例模板文件：

quiz_list.html：

{% extends 'base.html' %}

{% block content %}
  <h1>Quiz List</h1>
  <ul>
    {% for quiz in quizzes %}
      <li><a href="{% url 'exam:quiz_detail' quiz.id %}">{{ quiz.title }}</a></li>
    {% endfor %}
  </ul>
{% endblock %}

quiz_detail.html：

{% extends 'base.html' %}

{% block content %}
  <h1>{{ quiz.title }}</h1>
  <p>{{ quiz.description }}</p>
  <ul>
    {% for question in questions %}
      <li>{{ question.text }}</li>
      <form method="post" action="{% url 'exam:take_quiz' quiz.id %}">
        {% csrf_token %}
        <input type="text" name="{{ question.id }}">
      {% endfor %}
      <button type="submit">Submit</button>
      </form>
  </ul>
{% endblock %}

take_quiz.html：

{% extends 'base.html' %}

{% block content %}
  <h1>{{ quiz.title }}</h1>
  <ul>
    {% for question in questions %}
      <li>{{ question.text }}</li>
      <form method="post" action="{% url 'exam:take_quiz' quiz.id %}">
        {% csrf_token %}
        <input type="text" name="{{ question.id }}">
      {% endfor %}
      <button type="submit">Submit</button>
      </form>
  </ul>
{% endblock %}

quiz_result.html：

{% extends 'base.html' %}

{% block content %}
  <h1>Your score is {{ score }} out of {{ questions.count }}.</h1>
{% endblock %}

7. 运行Django项目

最后，我们需要在终端中运行以下命令来启动Django项目：

python manage.py runserver

然后，我们就可以在浏览器中访问“http://localhost:8000/”来查看考试系统了。
