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> " %(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> "%(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)

from django.conf.urls import url from django.shortcuts import HttpResponse,redirect class CusotmerConfig(ModelStark): def display_gender(self,obj=None,header=False):

temp=[]
for course in obj.course.all():

temp.append(s)
return mark_safe("".join(temp)) # list_display = ["name",'gender','course',"consultant",]
list_display = ["name",display_gender,display_course,"consultant",] def cancel_course(self,request,customer_id,course_id):
print(customer_id,course_id) obj=Customer.objects.filter(pk=customer_id).first()
obj.course.remove(course_id)
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)
