Django实战【五】—教学管理模块代码实现

一、教学模块实现

1.班级课程记录展示

客户成功转化后,就成为我们教学机构的学生,既然是我们学生,那么他是报名的什么课程啊,还有报名的具体是哪一期啊?

学校根据学生报名课程来划分班级,而我们的班级记录表就是用来记录某个班级某一天课程的详细信息,比如课程节次,课程内容,课程作业内容等等。

学生学习记录表就是用来记录某个班级的每一位学生在某一天的课程学习信息,比如他的考勤,作业提交情况,老师对作业的批语等等。

对应的数据表结构之前已详细介绍,不再赘述。

from django.db import models

教学系统详细表结构

在实现需求之前我们模拟一些数据量,数据内容大致如下:

Django实战【五】—教学管理模块代码实现_第1张图片

班级课程url

项目下的url分发

url(r'^education/', include("education.urls")),

education下的url写法

from education.views import education
from django.conf.urls import url

urlpatterns = [
    # 班级课程记录展示
    url(r'^class/record/list/', education.ClassStudyRecord.as_view(), name="class_record"),
]

班级课程视图

班级信息展示url,展示课程的详细记录,在班级课程展示的页面中,有两个功能要实现:

  1. 对某个班级的学生进行批量创建学习记录。
  2. 通过点击班级详情可以批量修改该班级的所有学生的学习记录。
# 班级学习记录视图
class ClassStudyRecord(views.View):
    @method_decorator(login_required)  # 校验用户登录
    def dispatch(self, request, *args, **kwargs):
        res = super().dispatch(request,*args,**kwargs)
        return res

    def get(self,request):
        # 获取所有班级的课程记录
        all_records = models.ClassStudyRecord.objects.all()
        return render(request, "class_record_list.html", {"all_records":all_records})

    def post(self,request):
        # 获取批量操作类型
        operate = request.POST.get("operate")
        # 获取批量提交的班级课程记录id
        selected_id = request.POST.getlist("choose")
        print(operate)
        if hasattr(self,operate):  # 反射类中的批量操作方法
            getattr(self,operate)(selected_id)
        return self.get(request)

    def batch_create(self,selected_id):
        for class_record_id in selected_id:
            # 根据班级课程记录查到多有的学生对象.
            # 注意班级和学生,一对多关联,通过班级反向找学生,类名小写_set.all(),但是外键字段取了related_name,所以直接使用别名students.all()
            all_students = models.ClassStudyRecord.objects.get(pk=class_record_id).class_obj.students.all()
            # print(all_students)
            # 给所有学生创建一条学习记录,只填好学生姓名,和所属的哪一节课程.
            li = []
            for student in all_students:
                # 根据每一个学生实例化一个学生学习记录对象
                student_record = models.StudentStudyRecord(
                    student=student,
                    class_study_record_id=class_record_id
                )
                li.append(student_record)
            # 批量创建记录
            models.StudentStudyRecord.objects.bulk_create(li)

前端页面html写法

批量创建通过select和input的checkbox来提交批量创建的类型和需要批量创建的记录对象。

班级课程记录

班级课程记录页面效果

Django实战【五】—教学管理模块代码实现_第2张图片

2.学生学习记录展示和批量修改

我们在班级课程展示页面中实现了一个详情连接,点击详情可以批量修改这个班级所有学生的记录。

然后学生学习记录信息也有一个展示页面,这里学生学习信息页面展示视图和批量编辑视图我们通过一个视图来实现,get处理页面展示,post处理批量修改的数据保存。

urls.py文件

# 学员学习记录展示
url(r'^student/record/list/(\d+)?/?', education.StudentStudyRecord.as_view(), name="student_record"),

视图文件的写法

学生学习记录的批量修改,可以通过两种方式实现。

  1. 获取某个班级的所有学生学习记录,并且获取学生中字段的选项数据,生成下拉框,或者输入框,用来获取提交的批量数据。
  2. 通过modelformset组件,自动生成批量修改的前端页面。

这里我们详细介绍一下modelformset方法的使用:生成批量修改页面,并能根据提交的数据批量保存到数据库。

为什么使用modelformset?

我们知道modelform可以生成单条记录的修改页面,但是无法解决多条记录的批量修改页面。所以modelform对于这种场景无法适用。

而modelformset可以根据你传递的多条记录,根据这些记录对象生成批量修改的页面,并且批量保存到数据库。

具体使用方法:

使用modelfromset需要导入一个django的内置模块

from django.forms.models import modelformset_factory

既然是modelformset,那么也当然少不了modelform,我们在education应用下froms文件夹下新建formauth.py,写入我们需要的modelform

from django import forms
from student import models


class StudentStudyRecordMF(forms.ModelForm):
    class Meta:
        model = models.StudentStudyRecord  # 指定一个表
        # fields = '__all__'
        fields = ['score','homework_note']  # 只验证两个字段,其他字段放行

在视图中使用

# 第二种方式,通过使用modelformset来生成批量修改的页面
    def batch_edit_mfs(self,request,class_record_id):
        # 通过班级记录id,找到班级课程的那一条记录
        class_record_obj = models.ClassStudyRecord.objects.get(pk=class_record_id)

        # 通过班级对象,找到这节班级课程的所有学生学习记录
        all_records = models.StudentStudyRecord.objects.filter(
            class_study_record=class_record_obj,
        )

        # 实例化一个form_set对象
        form_set_obj = modelformset_factory(
            model=models.StudentStudyRecord,  # 指定一张表
            form=StudentStudyRecordMF,  # 指定一个modelform
            extra=0  # 可以指定生成表中,新建数据的行数,看页面效果就理解了
        )

        # 将所有的学生学习记录传给form_set对象的queryset
        all_records = form_set_obj(queryset=all_records)

        return render(request,"student_record_edit.html",{"class_record_obj":class_record_obj,"all_records":all_records})

前端页面中的使用modelformset

<form action="" method="post">
                        {% csrf_token %}
                        <div class="input-group" style="width: 220px;margin-bottom: 5px;margin-left: 15px">

modelformset前端使用

学生学习记录的视图

虽然我们只着重说了modelformset的使用,但是在视图函数处理中,我把普通方式(自己手动遍历数据,写标签展示)和modelformset自动生成的方式都写了。有兴趣可以详细查看。

学生学习记录展示

前端html文件

前端页面也有两个,当我们想直接访问所有学生的学习记录时,我们直接请求这个url,而并没有传递班级记录id,这个时候是返回页面展示的html。

student_record_list
