流程思路

---

models.py

model设计思路：

具体参考：https://github.com/Fangqihan/CRM-Kingadmin/blob/master/crm/models.py

1、报名信息录入

urls.py

from django.conf.urls import url,include
from crm import views

urlpatterns = [
    url(r'^enroll/$', views.add_student, name='add_student'),  # 第一步：报名信息录入
]

views.py

@login_required
def add_student(request):
    """销售人员 添加 报名学生"""
    # 1、获取所有咨询用户信息
    customers = models.CustomerInfo.objects.all()
    # 2、获取所有校区
    branches = models.Branch.objects.all()
    # 3、获取所有销售人员
    consultants = models.UserProfile.objects.filter(role__title='销售').exclude(id=1)

    if request.method == 'POST':
        # 4、获取提交的信息，包括 学生、选择的班级、咨询顾问姓名的id
        customerid = request.POST.get('customer')
        class_gradeid = request.POST.get('class_grade')
        consultantid = request.POST.get('consultant')
        
        from crm.models import StudentEnrollment
        if consultantid and class_gradeid and consultantid:
            # 5、数据合法则创建 StudentEnrollment 对象
            student_enroll = StudentEnrollment.objects.create(
                customer_id=customerid,
                class_grade_id=class_gradeid,
                consultant_id=consultantid
            )
            print('学生创建成功')
            
            # 6、生成学生完善信息 链接
            enroll_links = 'http://127.0.0.1:8008/crm/enroll/%s/' % student_enroll.id
            print(enroll_links)

    return render(request, 'crm/student_enroll.html', locals())

创建StudentEnrollment对象的约束：

class StudentEnrollment(models.Model):
    """学员报名"""
    ...

    class Meta:
        # 在一个班级内，customer必须是唯一的，否则会报错
        unique_together = ['customer', 'class_grade']
        db_table = '学生报名'

student_enroll.html

                $('#class_lst').append(ele)
            }
        })
    })
</script>

动态获取对应校区的班级列表

1、urls.py

url(r'^get_classes/(d+)/$', views.get_classes, name='get_classes'),

2、views.py

from crm.models import Branch, ClassList
import json


def get_classes(request, id):
    # 1、确定校区
    branch = Branch.objects.filter(id=int(id)).first()
    
    # 2、获取校区内所有班级values信息
    classes = list(ClassList.objects.filter(branch=branch).values(
        'id', 'branch__name', 'course__name', 'semester'))
    # [{'id': 1, 'branch__name': '上海', 'course__name': 'go语言', 'semester': 1},]

    # 3、返回班级列表的json数据
    return HttpResponse(json.dumps(classes), content_type="application/json")

生成完善信息链接

1、前端：

{% if enroll_links %}
    <label class="control-label" style="color: green">创建成功，请将链接发送给学员</label>
    <div class="">
        <input value="{{ enroll_links }}" class="form-control">
    </div>
{% endif %}

2、views.py：

from crm.models import StudentEnrollment
if consultantid and class_gradeid and consultantid:
    student_enroll = StudentEnrollment.objects.create(
        customer_id=customerid,
        class_grade_id=class_gradeid,
        consultant_id=consultantid
    )
    print('学生创建成功')
    enroll_links = 'http://127.0.0.1:8008/crm/enroll/%s/' % student_enroll.id
    print(enroll_links)
