django客户管理系统源码
一、客户管理系统增删改查
1.业务回顾
大家还记得我们项目的三大块吧，第一个就是客户管理。
客户管理系统是提供给网咨、销售人员来查看客户信息、增加客户、修改客户信息的。当然客户在我们项目中还有公户和私户的区别，公户私户实际是由销售总监根据销售的业务能力来合理分配，从而使客户转化率最大化。
销售人员通过分配到的客户，存放在自己的私户中，通过不断的跟进，交流，让客户报名。期间的跟进记录我们应当都存入数据库，以便以后的继续跟进。
由于该博客仅用于知识点的分享实现，所以我们这里只实现一个完整的功能块，其他类似的就不展示了，所以我们这里只实现客户的信息增删改查，也就是customer应用下的客户数据。
2.公共客户数据的增删改查url
项目下urls路由分发对应的请求到customer应用下
url(r'^customer/', include("customer.urls")),
- 1
customer应用下的增删改查url
from django.conf.urls import url
from customer.views import customer
urlpatterns = [
# 公户数据展示url
url(r'^common/list', customer.CommonList.as_view(), name="common_list"),
# 公户信息添加url
url(r'^common/add/', customer.CommonAdd.as_view(), name="common_add"),
# 公户信息修改url
url(r'^common/edit/(\d+)/', customer.CommonEdit.as_view(), name="common_edit"),
# 公户信息删除
url(r'^common/del/(\d+)/', customer.CommonDel.as_view(), name="common_del"),
]

3.公户数据的展示视图和模板
关于客户信息的相关视图我们放在customer下的views文件夹下的customer.py中。
公户信息展示几点注意点：
- 在客户数据展示的视图中我们使用了django自带的auth认证装饰器，装饰器在验证失败后会跳转login页面，但是django默认配置的跳转login页面url并不是我们想要的，需要我们在settings中配置一下。
# 配置登录认证失败跳转的页面
LOGIN_URL = '/crmweb/login/'

- 在数据展示页面中，还使用了自定义分页，自定义分页博客中有，就不详述了，想要查看点这里：Django框架—分页器paginator 过滤器部分
公户展示视图写法
公户信息展示中实现了两个额外功能
- 查询功能
查询功能的实现，是基于form表单通过get提交select框和input框，select框用来提交查询的条件，input框提交查询的查询参数。
后端从get请求中获取前端参数，根据select提交的值来确定通过什么字段来查询，根据input的值来确定查询条件。
<form action="" method="get" class="navbar-form navbar-left"> <div class="input-group"> <div class="input-group-btn btn-info"> <select name="condition" id="search" class="btn input-group-sm btn-info" style="border: 0"> <option value="" readonly>条件</option> <option value="qq_name">昵称</option> <option value="qq">QQ号</option> </select> </div> <input type="text" name="q" class="form-control" placeholder="Search..."> <span class="input-group-btn"> <button type="submit" id="search-btn" class="btn btn-flat"> <i class="fa fa-search"></i> </button> </span> </div> </form>

- 批量操作功能
批量操作功能的实现，也是通过form表单post请求提交数据，在类中定义一系列批量操作的方法。
根据前端select提交的option选项中的value值，也就是字符串来反射类中的批量操作方法，根据表格中提交的记录id来批量修改。
from django import views from customer import models from django.db.models import Q, Count from django.shortcuts import ( render, redirect, reverse, HttpResponse ) from customer.forms import formAuth from django.contrib.auth.decorators import login_required from django.utils.decorators import method_decorator from utils.customPaginator import Paginator # 公户数据展示 class CommonList(views.View): @method_decorator(login_required) # 装饰器函数验证是否登录 def dispatch(self, request, *args, **kwargs): res = super().dispatch(request, *args, **kwargs) return res def get(self, request): # 查询公户全部数据 all_customers = models.Customer.objects.filter(consultant__isnull=True, status="unregistered").order_by( "-pk") # 使用Q查询拼接查询条件 condition = request.GET.get("condition", "") # 获取搜索的条件分类 query = request.GET.get("q", "") # 获取搜索的条件 if condition and query: # 如果有查询调参数，两个参数都有，根据查询参数查询后找到数据 condition = condition + "__contains" q = Q() # Q实例化生成q对象，q对象可以帮我们拼接字符串为 condition__contians= xx的关键字参数传到filter中。 q.children.append((condition, query)) all_customers = all_customers.filter(q) # 开始分页展示 data_counts = all_customers.count() # 获取分页的总数据数量 # 生成一个分页对象 paginator = Paginator(request, data_counts, 10) # 获取当前页展示数据的范围 try: # 异常是否查到了数据，查到了才切片，不然会报错 all_customers = all_customers[paginator.start:paginator.end] except Exception: pass # 获取分页的标签 paginator_tag = paginator.paginate() # 调用定义好的分页方法 # 获取跳转页的标签 jump_tag = paginator.jump_page() # 调用定义好的跳转页方法获取跳转页标签 jump_js = paginator.jump_js() # 调用定义好的跳转页方法获取跳转页js代码 # fixme 这里我实现的用户被选走的提示方式有点low，暂时先这样吧，而且在实际业务中，公户转私户应该是由销售总监分配的，而不是比谁先抢到。 name_str = None # 客户被选走的错误提示 if "*customer*" in request.path: name_list = request.path.split("*customer*")[1:] name_str = ','.join(name_list) # 返回response对象，以及需要渲染的数据 return render(request, "common_list.html",{"all_customers": all_customers, "paginator_tag": paginator_tag,"jump_tag": jump_tag, "jump_js": jump_js, "name_str": name_str}) def post(self, request): operate = request.POST.get("operate") # 获取用户提交的批量操作类型 if operate: # 如果有，去反射类中对应的批量操作方法 if hasattr(self, operate): func = getattr(self, operate) if callable(func): ret = func(request) # 执行批量操作方法 if ret: # 函数有返回值，也就是有被别的销售提前选走的客户 info = "" for obj in ret: # fixme 客户被任选走，在前端提示哪些客户被选走，这里我放在路径中，并不太好，目前就这样实现，以后有更好的办法再更新 info = info + "*customer*" + obj.__str__() url = request.path + info # 拼接url，携带提示信息 return redirect(url) return redirect(request.path) else: return HttpResponse("访问连接有误！") return HttpResponse("访问连接有误！") return redirect("common") def batch_delete(self, request, *args, **kwargs): """批量删除客户""" # 实际工作场景中并不是真的删除，而是修改该条数据在数据库的修改状态 choose_list = request.POST.getlist("choose") models.Customer.objects.filter(pk__in=choose_list).delete() def batch_update(self, request, *args, **kwargs): """批量更新客户状态""" choose_list = request.POST.getlist("choose") models.Customer.objects.filter(pk__in=choose_list).update(status="studying") def batch_c2p(self, request, *args, **kwargs): """批量公户转私户操作""" choose_list = request.POST.getlist("choose") # 获取选中的客户id，注意通过getlist来获取，获取一个列表 customer_list = models.Customer.objects.filter(pk__in=choose_list) # 根据客户id查到客户 has_choosed = [] # 定义一个列表 for customer_obj in customer_list: if customer_obj.consultant: # 如果客户被别人选了，放到已选列表 has_choosed.append(customer_obj) else: # 如果还没有备选则选择并保存 customer_obj.consultant = request.user customer_obj.save() # 通过save方法保存到数据库 return has_choosed # 返回已经被选择的用户 公户展示及批量操作视图

base.html
我们之前说过项目模板是用的开源的模板，这里我们是使用一个base页面，其他页面结构相同的都来继承这个base页面。
话说还记得模板继承的用法把，这里简单回顾：
先提取公共页面到一个base.html文件中，对于需要根据具体页面内容个性化定制的地方，使用block块来包裹，block块尽量多。
在继承的页面中，通过extends来继承base页面，对于需要自己定制的部分，在block中写入自己的内容。

实现后的页面效果
4.添加公户数据的视图和模板
添加公户视图函数
公户数据的添加，我们这里是通过modelform组件写的，所以先在customer应用下forms文件夹下formAuth.py中定义一个ModelForm。
from django import forms from customer import models # 顾客添加form认证 class CustomerAddMF(forms.ModelForm): # 定义添加数据使用的ModelForm class Meta: model = models.Customer # 指定一张表 fields = "__all__" # 指定字段，排除用exclude def __init__(self,*args,**kwargs): """重写init方法，批量添加标签样式""" super().__init__(*args,**kwargs) # 执行父类的init方法，必须 for field in self.fields: if field != "course": # 课程是多选框，不设置标签样式 self.fields[field].widget.attrs.update({"class":"forms-control",})

添加公户视图写法：
添加公户是通过modelform来实现的，get请求根据modeform实例化对象，返回前端，前端遍历对象来生成标签。post请求根据后端提交的数据给modelform去实例化，然后验证数据合法性，合法后才写入数据库。
# 添加公共客户记录 class CommonAdd(views.View): """添加公户记录视图""" @method_decorator(login_required) # 登录验证 def dispatch(self, request, *args, **kwargs): res = super().dispatch(request, *args, **kwargs) return res def get(self, request): form_obj = formAuth.CustomerAddMF() # 通过modelform实例化生成对象 return render(request, "common_add.html", {"form_obj": form_obj}) def post(self, request): # 实例化modelform并传入前端提交的数据 form_obj = formAuth.CustomerAddMF(request.POST) if form_obj.is_valid(): # 对提交数据验证 form_obj.save() # 合法保存到数据库 return redirect("common_list") else: # 不合法将原有数据返回给页面，并显示错误提示 return render(request, "common_add.html", {"form_obj": form_obj}) 添加公户视图

{% extends 'BASE.html' %} {% block head %} {{ block.super }} {% endblock head %} {% block title %} 新增客户 {% endblock title %} {% block content %} <div class="container-fluid"> <div class="row"> <div class="col-sm-7"> <form action="" method="post" class="form-horizontal" novalidate> {% csrf_token %} {% for field in form_obj %} <div class="form-group"> <label for="{{ field.id_for_label }}" class="control-label col-sm-2">{{ field.label }}</label> <div class="col-sm-8"> {{ field }} <span class="text-danger">{{ field.errors.0 }}</span> </div> </div> {% endfor %} <input type="submit" class="btn btn-success pull-right" value="添加"> </form> </div> </div> </div> {% endblock content %} {% block js %} {{ block.super }} {% endblock js %} common_add.html

5.编辑客户的视图和模板
编辑客户视图写法
# 修改公共客户记录 class CommonEdit(views.View): @method_decorator(login_required) # 登录验证状态 def dispatch(self, request, *args, **kwargs): res = super().dispatch(request, *args, **kwargs) return res def get(self, request, n): """ get请求，展示修改页面，其中展示原始数据 :param request: request请求 :param n: 前端传递过来的记录id :return: 返回response对象 """ customer_obj = models.Customer.objects.filter(pk=n).first() # 找到需要修改的客户对象 form_obj = formAuth.CustomerAddMF(instance=customer_obj) # 通过modelform实例化的instance参数指定一个客户对象，可以在前端页面中直接渲染原始数据。 return render(request, "common_add.html", {"form_obj": form_obj}) def post(self, request, n): """修改客户记录post请求""" customer_obj = models.Customer.objects.filter(pk=n).first() # 通过modelform实例化，传递页面提交的post数据，指定instance实例 form_obj = formAuth.CustomerAddMF(request.POST, instance=customer_obj) if form_obj.is_valid(): form_obj.save() # 合法后保存，注意如果实例化时，没有传实例，是创建记录，指定了实例才是修改数据 return redirect("common") else: # 数据不合法，保留页面和原始数据，并给出错误提示 return render(request, "common_add.html", {"form_obj": form_obj}) 编辑客户视图

修改客户记录html文件
modelform组件有一个功能，就是在实例化的时候，指定instance的对象，可以直接获取对象的值，并在页面中渲染出来，不需要我们再通过render单独传递数据渲染了。所以我们修改数据的页面的html文件与添加的页面没有差别，这里就直接使用上面common_add.html文件即可。
其次，在post请求提交数据后，modelform实例化对象的时候，如果直接传递request.post数据，通过modelform对象.save方法可以新建数据；如果指定了instance为哪个记录对象，save方法就是修改这个记录对象的数据。
6.删除客户的视图和模板
删除客户数据视图
# 删除公共客户记录
class CommonDel(views.View):
@method_decorator(login_required)
def dispatch(self, request, *args, **kwargs):
res = super().dispatch(request, *args, **kwargs)
return res
def get(self, request, n):
# 根据前端传递的客户id，查找客户对象
customer_obj = models.Customer.objects.filter(pk=n)
customer_obj.delete() # fixme 对象的delete方法删除，其实实际工作中不应是真的删除，而是修改该记录的删除状态为True，即可。
return redirect("common_list")

删除数据不需要页面展示，其实我们本应该在删除前有一个确认过程，而不是点击一下，就直接删除，这样可能会导致误删。至于确认删除的过程，我们可通过js代码来实现，这里我就不详细写了。
