十二章、学员报名流程开发 2
12.1.学员报名合同和证件信息上传
功能：
- 必须勾选报名合同协议
- 必须上传个人证件信息
- 最多只能上传三个文件
- 文件大小2M以内
- 列出已上传文件
（1）crm/urls.py
urlpatterns = [ #上传个人证件信息 url(r'^enrollment/(\d+)/fileupload/$', views.enrollment_fileupload,name='enrollment_fileupload'),]
（2）crm./views.py
建一个上传文件的文件夹
import os,jsonfrom django.views.decorators.csrf import csrf_exemptfrom django import conf@csrf_exemptdef enrollment_fileupload(request,enrollment_id): '''学员报名文件上传''' enrollment_upload_dir = os.path.join(conf.settings.CRM_FILE_UOLOAD_DIR,enrollment_id) #第一次上传图片就创建目录，学员上传第二章图片的时候，会判断目录是否已经存在 #因为如果目录存在还mkdir就会报错，所以这里要做判断 if not os.path.isdir(enrollment_upload_dir): os.mkdir(enrollment_upload_dir) #获取上传文件的对象 file_obj = request.FILES.get('file') #最多只允许上传3个文件 if len(os.listdir(enrollment_upload_dir)) <= 3: #把图片名字拼接起来（file.name：上传的文件名字） with open(os.path.join(enrollment_upload_dir,file_obj.name),'wb') as f: for chunks in file_obj.chunks(): f.write(chunks) else: return HttpResponse(json.dumps({ 'status':False,'err_msg':'最多只能上传三个文件'})) return HttpResponse(json.dumps({ 'status':True,}),)def enrollment(request,enrollment_id): '''学员在线报名表地址''' enrollment_obj = models.StudentEnrollment.objects.get(id=enrollment_id) if request.method == 'POST': customer_form = form.CustomerForm(instance=enrollment_obj.customer,data=request.POST) if customer_form.is_valid(): customer_form.save() return HttpResponse("你已成功提交报名信息，请等待审核，欢迎加入仙剑奇侠传") else: customer_form = form.CustomerForm(instance=enrollment_obj.customer) # 列出学员已上传的文件 upload_files = [] enrollment_upload_dir = os.path.join(conf.settings.CRM_FILE_UOLOAD_DIR, enrollment_id) if os.path.isdir(enrollment_upload_dir): upload_files = os.listdir(enrollment_upload_dir) return render(request,'crm/enrollment.html',locals()) （3）settings.py
#学员个人信息图片上传路径CRM_FILE_UOLOAD_DIR = os.path.join(BASE_DIR,'crm/upload_files/enrollment_data',)
（4）crm/enrollment.html
css和js放到statics下面
{#templates/crm/enrollment.html#}{% extends 'index.html' %}{% load staticfiles %}{% block extra-css %} {% endblock %}{% block body %} 仙剑奇侠传|学员报名
学员在线报名
已上传文件列表
{% for file in upload_files %} - { { file }}
{% endfor %}
{% endblock %}{% block extra-js %} {% endblock %}
效果：
合同
上传证件信息（直接把文件拖进去就可以了）
12.2.合同审核
（1）学员提交报名信息后，把contract_agreed改为True，并保存提交的时间
（2）提交报名信息后，就应该是等待审核状态
（3）已经生产报名链接的，点“下一步”，跳转“合同审核”页面
- 没有生产报名链接的点“下一步”，生产报名连接
- 已经生成过的，点“下一步”，会报错，因为赢生成过了链接
- 所以在这里要抓住这个异常，生成过的点“下一步”，应该是跳到“合同审核”页面
抓住异常
@login_requireddef stu_enrollment(request): '''学员报名''' customers = models.CustomerInfo.objects.all() class_lists = models.ClassList.objects.all() if request.method == 'POST': #获取提交的客户id和班级id，然后生成报名链接 customer_id = request.POST.get('customer_id') class_grade_id = request.POST.get('class_grade_id') try: enrollment_obj = models.StudentEnrollment.objects.create( customer_id = customer_id, class_grade_id = class_grade_id, consultant_id = request.user.userprofile.id ) #已经生成过报名链接，就进入审核页面 except IntegrityError as e: enrollment_obj = models.StudentEnrollment.objects.get(customer_id = customer_id,class_grade_id = class_grade_id) if enrollment_obj.contract_agreed: return redirect("/crm/stu_enrollment/%s/contract_audit/"% enrollment_obj.id) #生成链接返回到前端 enrollment_link = "http://localhost:8000/crm/enrollment/%s"% enrollment_obj.id return render(request,'crm/stu_enrollment.html',locals())
合同审核
（4）crm/urls.py
#合同审核 url(r'^stu_enrollment/(\d+)/contract_audit/$', views.contract_audit,name='contract_audit'),
（5）crm/views.py
- 获取到学员信息表单
- 勾选审核后，提交
- 后台：把学生加到对应班级里面
- 把学生的状态改成报名
@login_requireddef contract_audit(request,enrollment_id): '''合同审核''' enrollment_obj = models.StudentEnrollment.objects.get(id=enrollment_id) if request.method == 'POST': enrollment_form = form.EnrollmentForm(instance=enrollment_obj,data=request.POST) if enrollment_form.is_valid(): enrollment_form.save() stu_obj = models.Student.objects.get_or_create(customer=enrollment_obj.customer)[0] #m2m, 添加班级 stu_obj.class_grades.add(enrollment_obj.class_grade_id) stu_obj.save() #改变报名 enrollment_obj.customer.status = 1 enrollment_obj.save() return redirect("/kingadmin/crm/customerinfo/%s/change"%enrollment_obj.customer.id) else: #拿到客户信息的表单 customer_form = form.CustomerForm(instance=enrollment_obj.customer) enrollment_form = form.EnrollmentForm(instance=enrollment_obj) return render(request,'crm/contract_audit.html',locals())
（6）crm/contract_audit.html
{#crm/contract_audit.html#}{% extends 'index.html' %}{% block right-content-container %}学员报名|合同审核
{% endblock %}
