2 CRM 讲师与学生，highcharts应用
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
5 上传作业(os模块)
6 下载作业
二、 初始化 ,studyrecord,
1、生成studyrecord
2、批量初始化迟到
class StudyRecordConfig(ModelStark): def patch_late(self, request, queryset): queryset.update(record='late') patch_late.short_description = '迟到' actions = [patch_late] site.register(StudyRecord, StudyRecordConfig)
3、get_field_display()
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 = '迟到' actions = [patch_late] site.register(StudyRecord, StudyRecordConfig)
三、初始化 course_record:批量生成学习记录
1、生成course_record
2、批量生成学习记录
class CourseRecordConfig(ModelStark): def patch_studyrecord(self, request, queryset): print(queryset) # <QuerySet [<CourseRecord: python基础班(9期) day11>]> temp = [] for course_record in queryset: student_list = Student.objects.filter(class_list=course_record.class_obj.pk) for student in student_list: obj = StudyRecord(student=student, course_record=course_record) temp.append(obj) StudyRecord.objects.bulk_create(temp) # 批量生成数据 patch_studyrecord.short_description = '批量生成学习记录' actions = [patch_studyrecord, ] site.register(CourseRecord, CourseRecordConfig)
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
2、 mark_safe
from django.utils.safestring import mark_safe
return mark_safe("<a href='/stark/crm/studyrecord/?course_record=%s'>记录</a>" % (obj.pk))
五、录入成绩
代码
class CourseRecordConfig(ModelStark): def score(self, request, course_record_id): """录入成绩view""" study_record_list = StudyRecord.objects.filter(course_record=course_record_id) print(study_record_list) score_choices = StudyRecord.score_choices if request.method == "POST": print(request.POST) # <QueryDict: 'score_4': ['100'], 'homeword_note_4': ['33']}> data = {} # dic = {1:{'homework_note':'good','score':'90'},2:{'homework_note':'nonono','score':'80'},} 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, val in data.items(): StudyRecord.objects.filter(pk=pk).update(**val) ''' # 方式1 if field == 'score': StudyRecord.objects.filter(pk=pk).update(score=value) else: StudyRecord.objects.filter(pk=pk).update(homework_note=value.strip()) ''' return redirect(request.path) # 跳转到当前url return render(request, 'score.html', locals()) def extra_url(self): """录入成绩url""" temp = [] temp.append(url('record_score/(\d+)', self.score)) return temp def record_score(self, obj=None, header=False): """录入成绩a标签""" 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_score] site.register(CourseRecord, CourseRecordConfig)
知识点
1、mark_safe
def record_score(self, obj=None, header=False): """录入成绩a标签""" if header: return "录入成绩" return mark_safe("<a href='record_score/%s'>录入成绩</a>" % (obj.pk))
2、添加额外的 extra_url
def extra_url(self): """录入成绩url""" temp = [] temp.append(url('record_score/(\d+)', self.score)) return temp
全局修改
3、form表单提交数据
class CourseRecordConfig(ModelStark): def score(self, request, course_record_id): """录入成绩view""" if request.method == "POST": print(request.POST) # <QueryDict: 'score_4': ['100'], 'homeword_note_4': ['33']}>
4、处理数据（ field, pk = key.rsplit('_', 1) ）
data = {} 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)
# dic = {1:{'homework_note':'good','score':'90'},2:{'homework_note':'nonono','score':'80'},}
5、更新数据
for pk, val in data.items(): StudyRecord.objects.filter(pk=pk).update(**val) ''' # 方式1 if field == 'score': StudyRecord.objects.filter(pk=pk).update(score=value) else: StudyRecord.objects.filter(pk=pk).update(homework_note=value.strip()) '''
6、跳转到当前页面
return redirect(request.path) # 跳转到当前url
7、get请求
study_record_list = StudyRecord.objects.filter(course_record=course_record_id) print(study_record_list) score_choices = StudyRecord.score_choices return render(request, 'score.html', locals())
8、上传数据
<select name="score_{{ study_record.pk }}" class="form-control"> {% for item in score_choices %} {% if study_record.score == item.0 %} <option selected value="{{ item.0 }}">{{ item.1 }}</option> {% endif %} <option value="{{ item.0 }}">{{ item.1 }}</option> {% endfor %} </select> <textarea name="homework_note_{{ study_record.pk }}" id="" cols="30" rows="3" class="form-control"> {{ study_record.homework_note }} </textarea>
9、score.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> <link rel="stylesheet" href="/static/bootstrap/css/bootstrap.css"> <script src="/static/js/jquery-1.12.4.min.js"></script> </head> <body> <h3>录入成绩</h3> <div class="container"> <div class="row"> <div class="col-md-9 col-md-offset-1"> <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>批语</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 }}" class="form-control"> {% for item in score_choices %} {% 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> {{ study_record.homework_note }} {% if study_record.homework_note %} <textarea name="homework_note_{{ study_record.pk }}" id="" cols="30" rows="3" class="form-control"> {{ study_record.homework_note }} </textarea> {% else %} <textarea name="homework_note_{{ study_record.pk }}" id="" cols="30" rows="3" class="form-control"></textarea> {% endif %} </td> </tr> {% endfor %} </tbody> </table> <input type="submit" class="btn btn-success pull-right"> </form> </div> </div> </div> </body> </html>
六、highcharts表的应用
1、应用
2、下载中心，cdn服务

更多文件详见 简数 CDN
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）
class StudentConfig(ModelStark): def score_view(self, request, stu_id): """查看成绩 view""" if request.is_ajax(): cid = request.GET.get('cid') sid = request.GET.get('sid') print(cid,sid) study_record_list = StudyRecord.objects.filter(student=sid,course_record__class_obj=cid) print('study_record_list',study_record_list) # 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']) return JsonResponse(dic,safe=False) else: student = Student.objects.filter(pk=stu_id).first() class_list = student.class_list.all() return render(request, 'score_view.html', locals()) def extra_url(self): """查看成绩url""" temp = [] temp.append(url(r"score_view/(\d+)", self.score_view)) return temp 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] list_display_links = ['customer'] site.register(Student, StudentConfig)
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
{% for cls in class_list %} <tr> <td>{{ cls }}</td> <td>{{ cls.tutor }}</td> <td> {% for teacher in cls.teachers.all %} <span>{{ teacher }}</span> {% endfor %} </td> <td><a class="check_chart" cid="{{ cls.pk }}" sid="{{ student.pk }}">点击查看</a> </td> </tr> {% endfor %}
9、ajax的get提交
<script type="text/javascript"> $('.check_chart').click(function () { $.ajax({ url: '', type: 'get', data: { cid: $(this).attr('cid'), sid: $(this).attr('sid') }, success: function (data) { console.log(data) } }) }) </script>
10、插入highchart代码
11、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>
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> <link rel="stylesheet" href="/static/bootstrap/css/bootstrap.css"> <script src="/static/js/jquery-1.12.4.min.js"></script> <script src="/static/charts/highcharts.js"></script> </head> <body> <h3>查看{{ student }}成绩</h3> <div class="container"> <div class="row"> <div class="col-md-9 col-md-offset-1"> <form action="" method="post"> {% csrf_token %} <table class="table table-bordered table-striped"> <thead> <tr> <th>班级</th> <th>班主任</th> <th>任课老师</th> <th>课程成绩</th> </tr> </thead> <tbody> {% for cls in class_list %} <tr> <td>{{ cls }}</td> <td>{{ cls.tutor }}</td> <td> {% for teacher in cls.teachers.all %} <span>{{ teacher }}</span> {% endfor %} </td> <td><a class="check_chart" cid="{{ cls.pk }}" sid="{{ student.pk }}">点击查看</a> </td> </tr> {% endfor %} </tbody> </table> </form> <div id="container" style="min-width:400px;height:400px"></div> </div> </div> </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) { {# console.log(data)#} {# console.log(data['day'])#} //显示chart图表 var chart = Highcharts.chart('container', { chart: { type: 'line' }, title: { text: '该学生的成绩记录' }, subtitle: { text: '数据来源: WorldClimate.com' }, xAxis: { categories: data['day'] }, yAxis: { title: { text: '分数' } }, plotOptions: { line: { dataLabels: { // 开启数据标签 enabled: true }, // 关闭鼠标跟踪，对应的提示框、点击事件会失效 enableMouseTracking: true } }, series: [{ //name: 'alex', data: data['score'] }] }); } }) }) </script> </body> </html>
八、 上传作业(os模块)、下载作业（未完成）
九、代码总结
1、目录结构
2、stark.py

5、stark/apps中 启动stark组件
6、settings设置templates路径，static路径
