1、講師與學生簡介

1.初始化  course_record, study_record.
2.學習記錄
3.錄入成績
4.顯示成績 ajax 查詢 柱狀圖展現成績 highcharts

5.上傳做業（os模塊）
6.下載做業

2、初始化course_record,study_record

錄入courserecord數據javascript

3、批量生成學習記錄

知識點css

1. 與course_record 關聯得班級對應得學生

    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:
            # 與course_record 關聯得班級對應得學生
            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 = "批量生成學習記錄"

4、查看學習記錄

知識點html

1. ?course_record=%s 過濾；

 　　　 mark_safe("<a href='/stark/crm/studyrecord/?course_record=%s'>記錄</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顯示；get_field_display

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

3. 批量處理遲到

 　　queryset.update(record="late")

    -----------------------
    
    def record(self, obj=None, header=False):
        if header:
            return "學習記錄"
        return mark_safe("<a href='/stark/crm/studyrecord/?course_record=%s'>記錄</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 = "遲到"
        actions = [patch_late]
    
    site.register(StudyRecord,StudyRecordConfig)

5、錄入成績

知識點前端

1. mark_safe

 mark_safe("<a href='record_score/%s'>錄入成績</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表單提交數據

    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. 處理數據（ 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. 更新數據

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

6. 跳轉當前頁面

 return redirect(request.path)

7. get請求

    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': '幫幫噠'}, 
             '35': {'score': '50', 'homework_note': '沒問題'}}

            '''

                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 "錄入成績"
        return mark_safe("<a href='record_score/%s'>錄入成績</a>"%obj.pk)

6、查當作績 - highcharts

知識點jquery

1. 查當作績

mark_safe("<a href='/stark/crm/student/score_view/%s'>查當作績</a>"%obj.pk)

2. 擴展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. 跨表查詢

準備數據：[['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,非字典須要加上 safe = False
return JsonResponse(data_list,safe=False)

7. 前端

注意：cid sid 用法； ajax 顯示 highcharts 柱狀圖
<a class="check_chart" cid="{{ cls.pk }}" sid="{{ student.pk }}">查當作績</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) {
                // 顯示柱狀圖
                var chart = Highcharts.chart('container', {
