Django 练习班级管理系统五 -- 查看老师列表

models.py 对应的配置

class Classes(models.Model):

    caption = models.CharField(max_length=32)

class Teacher(models.Model):

    name = models.CharField(max_length=32)

    cls = models.ManyToManyField('Classes')

修改 views.py

@auth

def handle_teacher(request):

    current_user = request.session.get('username')

    # teacher_list = models.Teacher.objects.all()

    # for obj in teacher_list:

    #     print(obj.id, obj.name, obj.cls.all())

    # 分页，获取第一页5位老师对应的记录

    teacher_list = models.Teacher.objects.filter(id__in=models.Teacher.objects.all()[0:5]).values('id', 'name', 'cls__id', 'cls__caption')

    result = {}

    for t in teacher_list:

        # 判断是否已在 result 中

        if t['id'] in result:

            # 判断 cls__id 的值是否为空

            if t['cls__id']:

                result[t['id']]['cls_list'].append({'id': t['cls__id'], 'caption': t['cls__caption']})

        else:

            # cls__id 有值

            if t['cls__id']:

                temp = [{'id': t['cls__id'], 'caption': t['cls__caption']},]

            else:

                # cls__id 没值

                temp = []

            # 给 result 字典添加值

            result[t['id']] = {

                'nid': t['id'],

                'name': t['name'],

                'cls_list': temp

            }

    return render(request, 'teacher.html', {'username': current_user, 'teacher_list': result})

修改 teacher.html

{% extends "layout.html" %}

{% block css %}

        .tag{

            display: inline-block;

            padding: 5px;

            border: 1px solid red;

            background-color: lightpink;

            cursor: pointer;

        }

{% endblock %}

{% block content %}

    <h1>老师列表</h1>

    <table border="1">

        <thead></thead>

        <tbody>

            {% for dic in teacher_list.values %}

                <tr>

                    <td>{{ dic.nid }}</td>

                    <td>{{ dic.name }}</td>

                    <td>

                        {% for c in dic.cls_list %}

                            <span class="tag" nid="{{ c.id }}">{{ c.caption }}</span>

                        {% endfor %}

                    </td>

                </tr>

            {% endfor %}

        </tbody>

    </table>

{% endblock %}

{% block js %}

    <script>

        $(function () {

            $('#menu_teacher').addClass('active');

        })

    </script>

{% endblock %}
