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'],

'''
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)
'''

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'
},
title: {
text: '查看学生每天的成绩'
},
subtitle: {

},
xAxis: {

});
}
}) }); </script>
