一、讲师与学生简介

1 初始化 course_record,studyrecord,

2 考勤

3 录入成绩

4 显示成绩 ajax 查询

二、 初始化 ,studyrecord

1、生成studyrecord

首先应该创建这一天的课程记录，然后批量生成所有学生到这一天的课程。

2、批量初始化迟到

    def path_late(self, request, queryset):
        queryset.update(record="late")
    path_late.short_description = "迟到"
    actions = [path_late]

    #点名这里因为大部分人是签到的，只有个别迟到，所以做一个批量迟到。

3、get_field_display()

这样显示的是迟到还是请假等具体，而不是choice的序号，但是老这样不行，后面会在源码进行优化。

class StudyRecordConfig(ModelStark):
    def display_record(self, obj=None, header=False):
        if header:
            return "记录"
        return obj.get_record_display()

    def display_score(self, obj=None, header=False):
        if header:
            return "成绩"
        return obj.get_score_display()

    list_display = ['student', 'course_record', display_record, display_score]

    def patch_late(self, request, queryset):
        queryset.update(record='late')

    patch_late.short_description = '批量迟到'
    actions = [patch_late]
site.register(StudyRecord, StudyRecordConfig)

 

在源码的这个地方做一下修改，以后只需要展示字段，会判定是否是choice，是的话直接显示对应的值，而不是序号。

三、初始化 course_record:批量生成学习记录

1、首先要生成当天的course_record

2、批量生成学习记录

比如今天是第95天,那么就是往这个95天的课程记录里把学生全部加进去。

    def path_studyrecord(self, request, queryset):
　　　　　print(queryset)       #　<QuerySet[<CourseRecord:python基础班（9期） day11>]>
        temp = []
        for course_record in queryset:
            #与course_record关联的班级对应的所有学生应该取出。
            #手里有一个课程的记录（python9期的94天课程），拿班级ID是这个记录的班级对象的主键值的学生过滤出来。
            student_list=Student.objects.filter(class_list__id=course_record.class_obj.pk)

            #用这些学生去创建一条条的StudyReord.
            for student in student_list:
                obj=StudyRecord(student=student,course_record=course_record)
                temp.append(obj)
        StudyRecord.objects.bulk_create(temp)
    path_studyrecord.short_description = "批量生成"
    actions = [path_studyrecord]
    #比如今天创建了一条9期95天的记录，然后应该把一个个的学生的情况加入到这里面来，可以用上面
    #的量生成一个班级的学生。不用一个一个的去添加。

四、 考勤  url跳转

1. ?course_record=%s 过滤；

from django.utils.safestring import mark_safe

class CourseRecordConfig(ModelStark):

    def record(self, obj=None, header=False):
        if header:
            return '学习记录'
        return mark_safe("<a href='/stark/crm/studyrecord/?course_record=%s'>记录</a>" % (obj.pk))

    list_display = ['class_obj', 'day_num', 'teacher', record]

site.register(CourseRecord, CourseRecordConfig)

全局修改

因为有着分页的过滤条件，所以原来的源码是只过滤list_filter列表中的字段。

想要过滤任意字段，就在源码中做了一下修改，直接让过滤字段不等于page，剩下的全过滤就好了。

五、录入成绩

代码

class CourseRecordConfig(ModelStark):
#这个就是录成绩的一个新建的页面。
    def score(self,request,course_record_id):
        if request.method == "POST":
            # 构建一个dict
            data = {}
            for key,value in request.POST.items():

                if key=="csrfmiddlewaretoken":
                    continue
                #前端的字段和主键是拼起来的，所以用spilt将字典和主键分割开。
                field,pk=key.rsplit("_",1)
                if pk in data:
                    data[pk][field]=value
                else:
                    data[pk]={field:value}

                #构建的字典格式：
                    data={1:{"score:90","homework_note":"xxx",2:{"score:80","homework_note":"qqq",}}

            for pk,update_data in data.items():
                #取到学习的主键值，过滤出来这条数据，把新的成绩和评语更新进入学习情况表内。
                StudyRecord.objects.filter(pk=pk).update(**update_data)
            return redirect(request.path)

        else:
        #这里表示是get请求，获取到某个班级某一条的所有学学习记录。
        #course_record里面有哪一个班级，也有哪一天。

        '''
        class CourseRecord(models.Model):
            """
            上课记录表
            """
            class_obj = models.ForeignKey(verbose_name="班级", to="ClassList",on_delete=models.CASCADE)
            day_num = models.IntegerField(verbose_name="节次", help_text="此处填写第几节课或第几天课程...,必须为数字")

            也就是上面2个字段。
        '''
            study_record_list=StudyRecord.objects.filter(course_record=course_record_id)
            record=StudyRecord.score_choices
            return render(request,"score.html",locals())

　　#构建URL
　　def extra_url(self):
        temp=[]
        temp.append(url(r'record_score/(\d+)',self.score))
        return temp
　　#构建录入成绩a标签
    def record_score(self,obj=None,header=False):
        if header:
            return "录入成绩"
        return mark_safe("<a href='record_score/%s'>录入成绩</a>"%obj.pk)

前端录入成绩的HTML模板form表单：

<form action="" method="post">
                {% csrf_token %}
                <table class="table table-bordered table-striped">
                    <thead>
                    <tr>
                        <th>学生姓名</th>
                        <th>考勤</th>
                        <th>成绩</th>
                        <th>评语</th>
                    </tr>
                    </thead>
                    <tbody>
                    {% for study_record in study_record_list %}
                        <tr>
                            <td>{{ study_record.student }}</td>
                            <td>{{ study_record.get_record_display }}</td>
                            <td style="width: 150px;padding: 10px 20px">
                                <select name="score_{{ study_record.pk }}" id="" class="form-control">
                                    {% for item in record %}
                                    这里做成一个select框选择评分，而且当学生的评分和循环的相等也就默认选中。
                                        {% if study_record.score == item.0 %}
                                            <option selected value="{{ item.0 }}">{{ item.1 }}</option>
                                        {% endif %}
                                        <option value="{{ item.0 }}">{{ item.1 }}</option>
                                    {% endfor %}

                                </select>
                            </td>
                            <td>
                                <textarea name="homework_note_{{ study_record.pk }}" id="" cols="30" rows="3"
                                          class="form-control">{{ study_record.homework_note }}</textarea>
                            </td>
                            这里的textarea标签也就默认取到数据展示在里面。
                            这样的意思是提交数据后，页面是最新的数据，而不是提交后刷新变为空。
                        </tr>
                    {% endfor %}
                    </tbody>
                </table>
                <input type="submit" class="btn btn-info pull-right">
            </form>

最后：

#老师录入成绩后，学生应该可以查看自己的成绩。
#查看成绩的URL。
#需要获取的是学生ID和班级ID，哪个学生查看自己某个班级的课程成绩。

#所以使用下面的柱状图来的更加直接。

六、highcharts表的应用

官网 https://www.hcharts.cn/

1、应用

2、下载中心，cdn服务

使用我们提供的 CDN 服务（免下载，高速、稳定）

您可以直接使用我们的 CDN 文件而不用下载，速度快和稳定是我们的 CDN 服务的优势

// Highcharts
<script src="https://cdn.hcharts.cn/highcharts/highcharts.js"></script>

// Highstock
<script src="https://cdn.hcharts.cn/highstock/highstock.js"></script>

// Highmaps
<script src="https://cdn.hcharts.cn/highmaps/highmaps.js"></script>

3、如何使用

1-导入code

2-引入js

3-引入html代码

4-引入js代码

5-替换data

七、 student学生表，显示成绩（ajax）

代码：

#查看成绩的URL。
    #需要获取的是学生ID和班级ID，哪个学生查看自己某个班级的课程成绩。
    def score_view(self,request,sid):
        if request.is_ajax():
            #ajax请求收到后
            cid=request.GET.get("cid")
            sid=request.GET.get("sid")
            #学习情况记录查找到学生id是sid的,并且通过字段course_record跨表到classlist表下拿到class_obj=cid等于这个班级ID的学习情况给取到。

            study_record_list=StudyRecord.objects.filter(student=sid,course_record__class_obj=cid)
            data_list=[]
            for study_record in study_record_list:
                day_num=study_record.course_record.day_num
                data_list.append(["day%s"%day_num,study_record.score])
            #构建柱状图需要的一个data结构，循环每一条学习记录，取到他的上课天数（day94）,和学习成绩
            #因为上课天数在CourseRecord里面，所以通过字段.course_record然后.day_num取到天数。
            return JsonResponse(data_list,safe=False)
        else:
            #取到这个学生对象。
            student=Student.objects.filter(pk=sid).first()
            class_list=student.class_list.all()   #一个同学可能报多个班，所以取到他的班级列表。
            return render(request,"score_view.html",locals())
 #生成url.
    def extra_url(self):
        temp=[]
        temp.append(url('score_view/(\d+)',self.score_view))
        return temp

    #创建查看成绩a标签的URL接口。
    def score_show(self,obj=None,header=False):
        if header:
            return "查看成绩"
        else:
            return mark_safe("<a href='score_view/%s'>查看成绩</a>"%obj.pk)
    list_display = ["customer","class_list",score_show]

知识点

1、 查看成绩a标签

 

    def score_show(self, obj=None, header=False):
        """查看成绩 a标签"""
        if header:
            return "查看成绩"
        return mark_safe('<a href="score_view/%s">查看成绩</a>' % (obj.pk))

    list_display = ['customer', 'class_list', score_show]

 

2、扩展url

    def extra_url(self):
        """查看成绩url"""
        temp = []
        temp.append(url(r"score_view/(\d+)", self.score_view))
        return temp

3、view视图

 

    def score_view(self, request, stu_id):
        """查看成绩 view"""

        student = Student.objects.filter(pk=stu_id).first()
        class_list = student.class_list.all()
        return render(request, 'score_view.html', locals())

 

4、request.is_ajax

        if request.is_ajax():
            cid = request.GET.get('cid')
            sid = request.GET.get('sid')

            print(cid,sid)

5、跨表查询

            study_record_list = StudyRecord.objects.filter(student=sid,course_record__class_obj=cid)

            print('study_record_list',study_record_list)
# study_record_list <QuerySet [<StudyRecord: python基础班(9期) day11-liang>, <StudyRecord: python基础班(9期) day12-liang>]>

6、构造数据

 

            # 方案1：构造数据 # [['day11', 85], ['day12', 90]]
            data_list = []
            for study_record in study_record_list:
                day_num = study_record.course_record.day_num
                data_list.append(['day%s' % day_num, study_record.score])

            print('data_list',data_list)

            #方案2：构造数据 dic = {day:[day11,day12],score:[85,90]}
            dic = {'day':[],'score':[]}
            for study_record in study_record_list:
                day_num = study_record.course_record.day_num
                dic['day'].append('day%s'%day_num)
                dic['score'].append(study_record.score)
            print(dic)
            print(dic['day'])
            print(dic['score'])

 

7、JsonResponse

返回JsonResponse,非字典需要加上 safe = False

from django.http import JsonResponse

return JsonResponse(data_list,safe=False)

8、前端显示table

            <tbody>
                {% for cls in class_list %}
                    <tr>
                        <td>{{ cls }}</td>   #班级名字
                        <td>{{ cls.tutor }}</td> #班主任
                        <td>
                            {% for teacher in cls.teachers.all %}
                                <span>{{ teacher }}</span>|   #取到每一个老师（可能多个老师）
                            {% endfor %}
                        </td>
                        <td><a class="check_chart" cid="{{ cls.pk }}" sid="{{ student.pk }}"><span>查看成绩</span></a></td>   给查看成绩一个点击事件。
                    </tr>
                {% endfor %}
                </tbody>
            </table>

        </div>
    </div>
</div>
<div id="container" style="width:900px;height:400px"></div>
<script>
    点击后发一个ajax请求，把点击的学生的iD和哪一个班的给发过去。
    $(".check_chart").click(function () {
        $.ajax({
            url: "",
            type: "get",
            data: {
                sid: $(this).attr("sid"),
                cid: $(this).attr("cid"),

            },
            #模板拿到数据以后，用hichart进行一个柱状图的展示。
            success: function (data) {
                var chart = Highcharts.chart('container', {
                    chart: {
                        type: 'column'
                    },
                    title: {
                        text: '课程成绩统计表'
                    },
                    subtitle: {
                        text: '数据截止 2018-06，来源: <a href="https://www.cnblogs.com/geogre123/">Student成绩表</a>'
                    },
                    xAxis: {
                        type: 'category',
                        labels: {
                            rotation: -45  // 设置轴标签旋转角度
                        }
                    },
                    yAxis: {
                        min: 0,
                        title: {
                            text: '分数 '
                        }
                    },
                    legend: {
                        enabled: false
                    },
                    tooltip: {
                        pointFormat: '分数: <b>{point.y:.1f}</b>'
                    },
                    series: [{
                        name: '总人口',
                        data: data,
                        dataLabels: {
                            enabled: true,
                            rotation: -90,
                            color: '#FFFFFF',
                            align: 'right',
                            format: '{point.y:.1f}', // :.1f 为保留 1 位小数
                            y: 10
                        }
                    }]
                });
            }
        })
    })
</script>

9、插入highchart代码

10、前端代码score_view.html

注意：cid sid 用法； ajax 显示 highcharts 柱状图
<a class="check_chart" cid="{{ cls.pk }}" sid="{{ student.pk }}">查看成绩</a>

八、代码总结

1、目录结构

2、stark.py
