# Create your models here. class Subject(models.Model): stem = models.CharField(max_length=1024, verbose_name='题干内容', blank=False, null=False) type = models.IntegerField(choices=Type, verbose_name='题目类型,单选还是多选') explain = models.CharField(max_length=512, verbose_name='题目答案解析', blank=False, null=False) class Meta: db_table = 'subject' verbose_name = '题干表' class Options(models.Model): options = models.IntegerField(choices=Option, verbose_name='选项ABCDEFGH') content = models.CharField(max_length=256, verbose_name='选项内容') subject = models.ForeignKey('Subject') class Meta: db_table = 'options' verbose_name = '选项表' unique_together = ('subject', 'content') ordering = ['options'] class Answer(models.Model): options = models.IntegerField(choices=Option, verbose_name='选项ABCDEFGH') subject = models.ForeignKey('Subject') class Meta: db_table = 'answer' verbose_name = '答案表' unique_together = ('subject', 'options') ordering = ['options']

这里题目类型对应的类型为choices即数字0对应单选数字1对应多选

选项表也是12345678分别对应选项ABCDEFGH

注意运行数据迁移命令的路径是在项目文件夹下 

D:\health>python manage.py makemigrations subject
D:\health>python manage.py migrate subject

　　登录数据库查看创建的表

E , 感觉功能、运动功能、联络功能系统 
人的心理现象包括心理过程和个性心理。 心理过程包括认识教程、情结与情感过程、意志教程三个相互联系的方面。 个性心理特征包括人的能力、气质、性格。具体表现在人的个性倾向性、个性心理特征和自我意识三个方面

　　首先插入题目和解析


mysql> insert into subject values(null,'人类心理现象包括',0,'人的心理现象包括心理过程和个性心理。 心理过程包括认识教程、情结与情感过程、意志教程三个相互联系的方面。 个性心理特征包括人的能力、气质、性格。具 体表现在人的个性倾向性、个性心理特征和自我意识三个方面');

　　id自增，题目为单选题


mysql> insert into options values(null,1,'心理活动过程',1);
Query OK, 1 row affected (0.00 sec)
mysql> insert into options values(null,2,'个性心理特征',1);
Query OK, 1 row affected (0.00 sec)
mysql> insert into options values(null,3,'认知，情感和意志力',1);
Query OK, 1 row affected (0.00 sec)
mysql> insert into options values(null,4,'心理活动过程和个性心理特征',1);
Query OK, 1 row affected (0.00 sec)
mysql> insert into options values(null,5,'感觉功能、运动功能、联络功能系统',1);
Query OK, 1 row affected (0.00 sec)

mysql> insert into answer values(null,4,1);
Query OK, 1 row affected (0.00 sec)

　　查看数据库


 　　三，在web页面展示数据


　　①设置路由

    {% for one in object_list %}
{#        显示题目题干 forloop.counter为显示序号 #}
        <p>{{ forloop.counter }}, {{ one.stem }}</p>
{#        显示选项以及对应选项的内容get_options_display为把选项1234显示成ABCD#}
        {% for options in one.options_set.all %}
            {{ options.get_options_display }}, {{ options.content }} </br>
        {% endfor %}
{#        显示答案get_options_display为把选项1234显示成ABCD#}
        {% for answer in one.answer_set.all %}
            {{ answer.get_options_display }}
        {% endfor %}
    {% endfor %}
</body>
</html>

　　web页面查看


 　　把答案和解析做成隐藏然后使用按键显示


<!DOCTYPE html>
<html lang="en">
    <meta charset="UTF-8">
    <title>健康管理师练习题</title>
</head>
{#    遍历数据库提取所有题目#}
    {% for one in object_list %}
{#        显示题目题干 forloop.counter为显示序号 #}
        <p>{{ forloop.counter }}, {{ one.stem }}</p>
{#        显示选项以及对应选项的内容get_options_display为把选项1234显示成ABCD#}
        {% for options in one.options_set.all %}
            {{ options.get_options_display }}, {{ options.content }} </br>
        {% endfor %}
{#        显示答案get_options_display为把选项1234显示成ABCD#}
        <p id="{{ one.id }}id" hidden>
        {% for answer in one.answer_set.all %}
            {{ answer.get_options_display }}
        {% endfor %}
        <input type = 'button' onclick=showp("{{ one.id }}id") value='答案'/>
        <p id="{{ one.id }}explain" hidden>{{ one.explain }}</p>
        <input type = 'button' onclick=showp("{{ one.id }}explain") value='解析'>
    {% endfor %}
<script>
    {#隐藏显示函数#}
    function showp(id){
        if (document.getElementById(id).style.display == 'inline') {
            document.getElementById(id).style.display = 'none';
        else {
            document.getElementById(id).style.display='inline';
</script>
</body>
</html>

　　把答案和解析先隐藏，添加按钮，如果答案是隐藏的则点击按钮显示答案如果答案是显示的则点击按钮隐藏答案，解析也是如此


　　这里把答案和解析包含在一个p标签内，id分别为使用one.id加字符串id拼接的即类似于1id 1explain的id这样保证每个p标签的id不重复并且在id内不会出现一些特殊字符导致id不可用的问题


 　　四，添加数据


class SubjectAddView(TemplateView):
    template_name = 'subject_add.html'
    def post(self, request):
        data = request.POST
        res = {'status': 0, 'msg': '添加成功'}
            subject = Subject()
            subject.stem = data.get('stem')
            subject.explain = data.get('explain')
            subject.type = data.get('type')
            print(data.getlist('option'))
            print(data.getlist('content'))
            print(data.getlist('explain'))
            print(data.getlist('answer'))
            subject.save()
            for one in data.getlist('option'):
                options = Options()
                options.subject_id = subject.id
                options.options = one
                options.content = data.getlist('content')[int(one)-1]
                options.save()
            for one in data.getlist('answer'):
                answer = Answer()
                answer.subject_id = subject.id
                answer.options = one
                answer.save()
        except Exception as e:
            print(e)
            res = {'status': 1, 'msg': '添加失败'}
        return JsonResponse(res)

 　　注意需要加载css js

　　首页增加一个跳转按钮至添加数据

　　注意：本次有bug 例如更新数据只能更新原有选项一样多的数量选项，不能添加选项，答案没有按原有答案选中，需要重新选


　　在首页添加一个更新数据的按键


　　这里直接删除题目应该会同时清除选修班表和答案表，如果删除是出现外键关联错误导致无法删除可以，修改代码先删除选修表和答案表以后再删除题目表


 Options.objects.filter(subject_id=data.get('id')).delete()
 Answer.objects.filter(subject_id=data.get('id')).delete()
 Subject.objects.get(id=data.get('id')).delete()

　　删除数据没有单独的模板，在index页面添加删除函数


function subject_delete(id) {
            if (confirm('确认删除吗？')) {
            {#alert(id)#}
                $.get("{% url 'subject_delete' %}?id=" + id,function (data) {
                if(data.status == 0) {
                    swal({
                        title: data.msg,
                        icon: "success",
                        confirmButtonText: '确定',
                    }, function () {
                        window.location.reload()
                    } else {
                    swal("删除失败", {
                        icon: "error",
