CRM - 讲师与学生

一、讲师与学生简介

1.初始化  course_record, study_record.
2.学习记录
3.录入成绩
4.显示成绩 ajax 查询 柱状图展示成绩 highcharts

5.上传作业（os模块）
6.下载作业

二、初始化course_record,study_record

录入courserecord数据

三、批量生成学习记录

知识点

1. 与course_record 关联得班级对应得学生

    students_list = Student.objects.filter(class_list__id = course_record.class_obj.pk)
    for student in students_list:
        student_obj = StudyRecord(course_record=course_record,student=student)
        temp.append(student_obj)

2. 批量插入

StudyRecord.objects.bulk_create(temp)  

    def patch_studyrecord(self,request,queryset):
        # print('queryset:--》',queryset)
        temp = []
        for course_record in queryset:
            # 与course_record 关联得班级对应得学生
            students_list = Student.objects.filter(class_list__id = course_record.class_obj.pk)
            for student in students_list:
                student_obj = StudyRecord(course_record=course_record,student=student)
                temp.append(student_obj)

        StudyRecord.objects.bulk_create(temp)

    actions = [patch_studyrecord]
    patch_studyrecord.short_description = "批量生成学习记录"

四、查看学习记录

知识点

1. ?course_record=%s 过滤；

 　　　 mark_safe("<a href='/stark/crm/studyrecord/?course_record=%s'>记录</a>"%(obj.pk))
        
　　　　改一下全局的：
        # if filter_field in self.list_filter:
        if filter_field !="page":
            filter_condition.children.append((filter_field, val))
        

2. record,score显示；get_field_display

        放到全局：
        if field_obj.choices:
            val = getattr(obj,"get_"+field+"_display")
        else:
            val = getattr(obj, field)

3. 批量处理迟到

 　　queryset.update(record="late")

    -----------------------

    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, record_score ]

    ---------------------

    class StudyRecordConfig(ModelStark):
        list_display = ['student','course_record','record','score']

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

        patch_late.short_description = "迟到"
        actions = [patch_late]

    site.register(StudyRecord,StudyRecordConfig)

五、录入成绩

知识点

1. mark_safe

 mark_safe("<a href='record_score/%s'>录入成绩</a>"%obj.pk)

2. 新增url

    def extra_url(self):
        temp = []
        temp.append(url(r'^record_score/(\d+)', self.score))
        return temp  

3. form表单提交数据

    request.post:
    '''
        <QueryDict: {'csrfmiddlewaretoken': ['muIrf7pwbxIueSJcKADRlZEGVbzzRZOaiGVkBV8DGYC2V9gmxZtyZgujddFtTojk'],
        'score_33': ['100'], 'homework_note_33': ['很好'],
        'score_34': ['85'], 'homework_note_34': ['棒'],
        'score_35': ['60'], 'homework_note_35': ['None']}>
    ''' 

4. 处理数据（ field, pk = key.rsplit('_', 1) ）

    data = {}  # data={"33":{"score":100,"homework_note":'xxx'},}
    for key,value in request.POST.items():
        if key == "csrfmiddlewaretoken":continue
        field, pk = key.rsplit('_', 1)

        if pk in data:
            data[pk][field] = value
        else:
            data[pk] = {field:value}

    print("data-->",data)
    '''
         {'33': {'score': '100', 'homework_note': '很好'},
         '34': {'score': '85', 'homework_note': '棒'},
         '35': {'score': '60', 'homework_note': 'None'}}
    '''

5. 更新数据

    for pk,update_data  in data.items():
        StudyRecord.objects.filter(pk=pk).update(**update_data)

6. 跳转当前页面

 return redirect(request.path)

7. get请求

    study_record_list = StudyRecord.objects.filter(course_record__id=course_record_id)
    score_choices = StudyRecord.score_choices
    return render(request,'score.html',locals())

    def score(self,request, course_record_id):
        if request.method == "POST":
            print('post::::', request.POST)
            '''
            <QueryDict: {'csrfmiddlewaretoken': ['muIrf7pwbxIueSJcKADRlZEGVbzzRZOaiGVkBV8DGYC2V9gmxZtyZgujddFtTojk'],
            'score_33': ['100'], 'homework_note_33': ['很好'],
            'score_34': ['85'], 'homework_note_34': ['棒'],
             'score_35': ['60'], 'homework_note_35': ['None']}>
            '''
            data = {}  # data={"33":{"score":100,"homework_note":'xxx'},}
            for key,value in request.POST.items():
                if key == "csrfmiddlewaretoken":continue
                field, pk = key.rsplit('_', 1)

                if pk in data:
                    data[pk][field] = value
                else:
                    data[pk] = {field:value}

            print("data-->",data)
            '''
             {'33': {'score': '90', 'homework_note': '很好'},
             '34': {'score': '80', 'homework_note': '帮帮哒'},
             '35': {'score': '50', 'homework_note': '没问题'}}

            '''
            for pk,update_data  in data.items():
                StudyRecord.objects.filter(pk=pk).update(**update_data)

            return redirect(request.path)

        else:
            study_record_list = StudyRecord.objects.filter(course_record__id=course_record_id)
            score_choices = StudyRecord.score_choices
            return render(request,'score.html',locals())

    def extra_url(self):
        temp = []
        temp.append(url(r'^record_score/(\d+)', self.score))
        return temp 

   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)

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

六、查看成绩 - highcharts

知识点

1. 查看成绩

mark_safe("<a href='/stark/crm/student/score_view/%s'>查看成绩</a>"%obj.pk)

2. 扩展url

temp.append(url(r'^score_view/(\d+)', self.score_view))

3. get

student = Student.objects.filter(pk=sid).first()
class_list = student.class_list.all()

4. request.is_ajax

sid = request.GET.get('sid')
cid = request.GET.get('cid')

5. 跨表查询

准备数据：[['day94', 85], ['day95', 85], ['day96', 60]]
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])

print('----',data_list)  # [['day94', 85], ['day95', 85], ['day96', 60]]

6. JsonResponse()

返回JsonResponse,非字典需要加上 safe = False
return JsonResponse(data_list,safe=False)

7. 前端

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>

<div id="container" style="width: 600px; height: 400px;"></div>

<script type="text/javascript">
    $('.check_chart').click(function () {
        $.ajax({
            url:"",
            type:"get",
            data:{
                cid:$(this).attr('cid'),
                sid:$(this).attr('sid')
            },
            success:function (data) {
                // 显示柱状图
                var chart = Highcharts.chart('container', {
                    chart: {
                        type: 'column'
                    },

                        labels: {

                        }
                    },
                    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
                        }
                    }]
                });
