    业务场景:

    2、数据库表设计

    1 、表之间的对应关系

    from django.db import models
    
    class Customer(models.Model):
        '''客户信息表'''
        pass
    
    class CustomerFollowUp(models.Model):
        '''客户跟进表'''
        pass
    
    class Course(models.Model):
        '''课程表'''
        pass
    
    class ClassList(models.Model):
        '''班级表'''
        pass
    
    class CourseRecord(models.Model):
        '''上课记录'''
        pass
    
    class StudyRecord(models.Model):
        '''学习记录'''
        pass
    
    class Enrollment(models.Model):
        '''报名表'''
        pass
    
    
    class UserProfile(models.Model):
        '''账号表'''
        pass
    
    class Role(models.Model):
        '''角色表'''
        pass

     2、详细表设计models.py

    View Code

     3、起步

    1、urls

    from django.conf.urls import url
    from django.contrib import admin
    
    from stark.service.stark import site
    urlpatterns = [
        url(r'^admin/', admin.site.urls),
        url(r'^stark/', site.urls),
    ]

    2、导入stark组件,配置

      将组件直接可以复制到CRM系统中,然后在app的setting中进行注册。

    3、CRM的Stark配置

    from .models import *
        from stark.service.stark import site
        
        site.register(Department)
        site.register(UserInfo)
        site.register(Course)
        site.register(School)
        site.register(ClassList)
        site.register(Customer)
        site.register(ConsultRecord)
        site.register(Student)
        site.register(CourseRecord)
        site.register(StudyRecord)
     

     将CRM的所有表全部注册到Stark组件中。

    4、录入数据

    注册完成开始录入一些测试数据,注册成功会出现下面的URL。

    1、School表

    2、员工表UserInfo

    3、班级表Classlist

    4、客户表Customer

    5、部门表Department

    6、课程表Course

     5、知识点

    1、limit_choices_to

    model与form组件的多对多关系如何渲染的

    limit_choices_to

        teachers = models.ManyToManyField(verbose_name='任课老师', to='UserInfo', related_name="abc",
                                          limit_choices_to={"depart__in": [1002, 1005]})
    tutor
    = models.ForeignKey(verbose_name='班主任', to='UserInfo', related_name='classes', limit_choices_to={"depart": 1001}, on_delete=True)

        #首先有一个limit_choice_to字段:
        teachers = models.ManyToManyField(verbose_name='任课老师', to='UserInfo',related_name="abc",limit_choices_to={"depart__in":[1002,1005]})
        #这样限定他的部门只能是linux和python学部的员工为任课老师,可以把班主任限制在销售部的员工。

    如下图:

     2、自定制 display_classname

    class ClassConfig(ModelStark):
    
    
        def display_classname(self,obj=None,header=False):
            if header:
                return "班级名称"
            class_name="%s(%s)"%(obj.course.name,str(obj.semester))
            return class_name
    
        list_display = [display_classname,"tutor","teachers"]
    
    
    site.register(ClassList,ClassConfig)

     

    3、obj.get_gender_display()  显示option的值(Django自带方法)

    #通过这个方法,可以取到对应的choice的值,而不是序号1或者2
    class
    CusotmerConfig(ModelStark): def display_gender(self,obj=None,header=False): if header: return "性别" return obj.get_gender_display() # list_display = ["name",'gender',"consultant",] list_display = ["name",display_gender,"consultant",]

     对比:

                                              

    4.mark_safe()

    通过mark_safe()可以让模板不进行转义,渲染成想要的标签等。

    from django.utils.safestring import mark_safe
    
    class CusotmerConfig(ModelStark):
         def display_course(self,obj=None,header=False):
            #通过这个方法,可以取到对应的choice的值,而不是序号1或者2
            if header:
                return "咨询课程"
            else:
                temp=[]
                #这里的obj是customer表的实例对象,也就是当前记录的对象
                #对象正向查询按字段,直接.字段名.all()取出所有课程对象。
                #然后course.name取到所有的课程。
                for course in obj.course.all():
                #在这里拼一个a标签,url是取消课程用的,应该是某一个人取消某一门课程,
                所以取到谁取消的,(obj.pk),取消哪一个课程(course.pk) ,课程名字(用于展示)
                    s = "<a href='/stark/crm/customer/cancel_course/%s/%s' style='border:1px solid #369;padding:3px 6px'><span>%s</span></a>&nbsp;" %(obj.pk, course.pk, course.name)
                    temp.append(s)
    
                return mark_safe("".join(temp))
    # list_display = ["name",'course',"consultant"]
    list_display = ["name",display_course,"consultant"]

    5、extra_url()  额外的url接口

        
    #在stark组件中构建一个空的列表,别的表没有额外URL就是空列表,如果前面定义了extra_url方法,那么就可以添加额外的URL接口。
    def extra_url(self): return []
    def get_urls_2(self): temp = [] model_name=self.model._meta.model_name app_label=self.model._meta.app_label temp.append(url(r"^add/", self.add_view,name="%s_%s_add"%(app_label,model_name))) temp.append(url(r"^(d+)/delete/", self.delete_view,name="%s_%s_delete"%(app_label,model_name))) temp.append(url(r"^(d+)/change/", self.change_view,name="%s_%s_change"%(app_label,model_name))) temp.append(url(r"^$", self.list_view,name="%s_%s_list"%(app_label,model_name)))      #在这里调用这个方法,直接加继承一个额外的URL。 temp.extend(self.extra_url()) return temp

    #在CRM的Stark里面,这样调用方法,可以额外添加一个URL。

      def extra_url(self):
        temp=[]
        temp.append(url(r'record_score/(d+)',self.score))
        return temp

    
    

    6、课程点击取消

    class CusotmerConfig(ModelStark):
    
        def display_course(self,obj=None,header=False):
            if header:
                return "咨询课程"
            temp=[]
            for course in obj.course.all():
           #这里渲染出来课程的a标签。 s
    ="<a href='/stark/crm/customer/cancel_course/%s/%s' style='border:1px solid #369;padding:3px 6px'><span>%s</span></a>&nbsp;"%(obj.pk,course.pk,course.name,) temp.append(s) return mark_safe("".join(temp)) # list_display = ["name",'gender','course',"consultant",] list_display = ["name",display_gender,display_course,"consultant",]

       #点击a标签,从那个接口的url发一个请求,
       def cancel_course(self,request,customer_id,course_id):
         # print(customer_id,course_id)
           obj=self.model.objects.filter(pk=customer_id).first() #取到这个取消课程的客户对象。
          obj.course.remove(course_id) #这个客户把课程ID为某一个的课程取消掉。 #把对象通过字段找到的课程remove掉,传入remove的课程ID
          #最后重新定向回来展示页面,这样可以做出一个点击课程就可取消的效果。
          return redirect(self.get_list_url())

    def extra_url(self):
            temp=[]
            temp.append(url(r"cancel_course/(d+)/(d+)",self.cancel_course))
            return temp
    
    site.register(Customer,CusotmerConfig)
