CRM客户关系管理系统（十一）

第十一章、学员报名流程开发 1

11.1.面包屑的制作

（1）table_obj_list.html页面面包屑

def table_obj_list

返回数据改成locals()

table_obj_list.html

kingadmin_tags.py

@register.simple_tag
def get_model_verbose_name(admin_class):

    return admin_class.model._meta.verbose_name

（2）change页面的面包屑

table_obj_change.html

<ol class="breadcrumb">
      <li><a href="/kingadmin/">Home</a></li>
      <li><a href="/kingadmin/{{ app_name }}">{{ app_name }}</a></li>
      <li><a href="/kingadmin/{{ app_name }}/{{ model_name }}/">{% get_model_verbose_name admin_class %}</a></li>
      <li class="active">{{ form_obj.instance }}</li>
    </ol>
    <h4 class="page-header">修改{{ form_obj.instance }}</h4>

（3）add页面的面包屑

因为add和change共用tags和html。所以要添加判断是add还是change

table__obj_change_component.html

kingadmin_tags.py

table_obj_add.html

 <ol class="breadcrumb">
      <li><a href="/kingadmin/">Home</a></li>
      <li><a href="/kingadmin/{{ app_name }}">{{ app_name }}</a></li>
      <li><a href="/kingadmin/{{ app_name }}/{{ model_name }}/">{% get_model_verbose_name admin_class %}</a></li>
      <li class="active">ADD {{ model_name }}</li>
    </ol>

    <h2 class="page-header">{% get_model_name admin_class %}</h2>
    <h4 class="page-header">添加{% get_model_name admin_class %}</h4>

11.2.报名流程和models设计

（1）后台修改左侧“客户库”的url

（2）左侧menu菜单添加“active”样式

kingadmin/index.html

如果当前的url 跟menu的url_name就添加“active”

 <ul class="nav nav-sidebar">
                    {% for role in  request.user.userprofile.role.select_related %}
                        {% for menu in role.menus.select_related %}
                            {% if request.path == menu.url_name %}
                                <li class="active"><a href="{% if menu.url_type == 0 %}{{ menu.url_name }}{% else %}{% url menu.url_name %}{% endif %}">{{ menu.name }}</a></li>
                            {% else %}
                                <li ><a href="{% if menu.url_type == 0 %}{{ menu.url_name }}{% else %}{% url menu.url_name %}{% endif %}">{{ menu.name }}</a></li>
                            {% endif %}
                        {% endfor %}
                    {% endfor %}
                </ul>

报名流程

销售发起报名流程，选择班级，发报名链接给学员
学员填写在线报名表，提交gerenxinxi，上传证件信息，同意培训协议
销售审核报名表，审核通过后，创建一条缴费记录，自动把学员添加到相应的班级，报名成功

models设计

添加三张表 crm/models.py

class ContractTemplate(models.Model):
    '''存储合同模板'''
    name = models.CharField(max_length=64)
    content = models.TextField()
    date = models.DateField(auto_now_add=True)


class StudentEnrollment(models.Model):
    """学员报名表"""
    customer = models.ForeignKey('CustomerInfo',on_delete=models.CASCADE)
    class_grade = models.ForeignKey('ClassList',on_delete=models.CASCADE)
    consultant = models.ForeignKey('UserProfile',on_delete=models.CASCADE)
    contract_agreed = models.BooleanField(default=False)
    contract_signed_date = models.DateTimeField(blank=True,null=True)
    contract_approved = models.BooleanField(default=False)
    consultant_approved_date = models.DateTimeField('合同审核时间',blank=True,null=True)

    class Meta:
        unique_together = ('customer','class_grade')

    def __str__(self):
        return '%s'% self.customer


class PaymentRecord(models.Model):
    '''存储学员缴费记录'''
    enrollment = models.ForeignKey('StudentEnrollment',on_delete=models.CASCADE)
    payment_type_choices = ((0,'报名费'),(1,'学费'),(2,'退费'))
    payment_type = models.SmallIntegerField(choices=payment_type_choices,default=0)
    amount = models.IntegerField('费用',default=500)
    consultant = models.ForeignKey('UserProfile',on_delete=models.CASCADE)
    date = models.DateTimeField(auto_now_add=True)

    def __str__(self):
        return '%s' %self.enrollment

班级关联合同表

修改student跟customer为一对一的关系

11.3.报名页面

流程

销售填写客户跟班级，点“下一步”提交
后台获取到客户id和班级id，在数据库中创建记录，并生成一个报名链接，返回到前端
前端显示报名链接，然后销售把报名链接发给用户

（1）crm/urls.py

# crm/urls.py

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

urlpatterns = [
    url(r'^$', views.dashboard,name='sales_dashboard'),
    #学员报名
    url(r'^stu_enrollment/$', views.stu_enrollment,name='stu_enrollment'),
]

（2）crm/views.py

@login_required
def stu_enrollment(request):

    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')
        enrollment_obj = models.StudentEnrollment.objects.create(
            customer_id = customer_id,
            class_grade_id = class_grade_id,
            consultant_id = request.user.userprofile.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())

（3）新建templates/crm/stu_enrollment.html

crm/index.html

crm/stu_enrollment.html

{#templates/crm/stu_enrollment.html#}

{% extends 'index.html' %}


{% block right-content-container %}

    <h3>学员报名页</h3>


<form class="form-horizontal" method="post">
    {% csrf_token %}
    <div class="form-group">
        <label for="inputEmail3" class="col-sm-2 control-label">客户</label>
        <div class="col-sm-10">
            <select name="customer_id" class="form-control">
                {% for customer in customers  %}
                    <option value="{{ customer.id }}">{{ customer }}</option>
                {% endfor %}
            </select>
        </div>
    </div>

    <div class="form-group">
        <label for="inputEmail3" class="col-sm-2 control-label">报名班级</label>
        <div class="col-sm-10">
            <select name="class_grade_id" class="form-control">
                {% for class_grade in class_lists  %}
                    <option value="{{ class_grade.id }}">{{ class_grade }}</option>
                {% endfor %}
            </select>
        </div>
    </div>

    <input type="submit" class="btn btn-success pull-right" value="下一步">

</form>

    {% if enrollment_link %}
        <p>请将此报名链接复制并发送给学员填写 {{ enrollment_link }}</p>
    {% endif %}

{% endblock %}

11.4.学员填写报名信息

添加学员注册url
添加CustomerInfo字段，身份证信息，紧急联络人，性别
有些字段是只读的，填写信息的时候不能修改，因为如果设置了只读(添加属性disabled=true)，提交的时候会报这些字段为空，导致提交错误
所以在前段添加了js代码，BeforeFormSubmit 在提交前去掉disable=true（因为数据库中有默认值，提交的时候就不会报错）
防止用户通过前端改html代码的方式改只读字段的信息，所以在form.py里面添加了一个自定义的验证方法（clean）,如果只读字段提交的时候信息跟数据库中默认的不一样，就报错

（1）crm/urls.py

# crm/urls.py

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

urlpatterns = [
    url(r'^$', views.dashboard,name='sales_dashboard'),
    #学员报名
    url(r'^stu_enrollment/$', views.stu_enrollment,name='stu_enrollment'),
    #学员注册
    url(r'^enrollment/(\d+)/$', views.enrollment,name='enrollment'),
]

（2）crm/models.py

CustomerInfo表添加字段

（3）crm/form.py

# crm/form.py

from django.forms import ModelForm
from crm import models
from django import forms

class CustomerForm(ModelForm):
    class Meta:
        model = models.CustomerInfo
        fields = "__all__"
        #不显示的字段
        exclude = ['consult_content','status','consult_courses']
        #只读的字段
        readonly_fields = ['contact_type','contact','consultant','referral_from','source']

    #django是通过“__new__”方法，找到ModelForm里面的每个字段的，然后循环出每个字段添加自定义样式
    def __new__(cls, *args, **kwargs):
        #cls.base_fields是一个元祖，里面是 所有的  【(字段名，字段的对象),(),()】
        for field_name in cls.base_fields:
            field_obj = cls.base_fields[field_name]
            #添加属性
            field_obj.widget.attrs.update({'class':'form-control'})

            if field_name in cls.Meta.readonly_fields:
                field_obj.widget.attrs.update({'disabled':'true'})
        return ModelForm.__new__(cls)

    #只读字段不让用户通过浏览器改html代码的方式改
    def clean(self):
        # 表单级别的错误
        if self.errors:
            raise forms.ValidationError(("Please fix errors before re-submit."))
        # means this is a change form ,should check the readonly fields
        if self.instance.id is not None:
            #取出只读字段，是一个字符串形式
            for field in self.Meta.readonly_fields:
                #通过反射取出字段的值（数据库里的数据）
                old_field_val = getattr(self.instance, field)
                #提交过来的数据
                form_val = self.cleaned_data.get(field)
                #如果两个数据不匹配
                if old_field_val != form_val:
                    #就提示只读字段不能修改
                    #add_error是字段级别的错误
                    self.add_error(field, "Readonly Field: field should be '{value}' ,not '{new_value}' ". \
                                   format(**{'value': old_field_val, 'new_value': form_val}))

（4）crm/views.py

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)

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