二、注册表需要知道的知识点
1、部门表相关
需求：默认编辑不要了，通过字段变成可点击的，具体是哪个字段不知道，可以自定义
edit_link = ["title"]
方法：拿到字段后判断这个字段是都在edit_link里面，
- 值变成可点击的
- 反向生成url
- 获取url的参数，拼接成_listfilter
具体实现：
StarkConfig类 # =============编辑链接================ edit_link = [] def get_edit_link(self): result = [] if self.edit_link: result.extend(self.edit_link) return result ChangeList类 self.edit_link = config.get_edit_link() def edit_link_tag(self,pk,text): params = QueryDict(mutable=True) query_str = self.request.GET.urlencode() #page=1 params[self.config._query_param_key] = query_str #要跳转的路径http://127.0.0.1:8080/index/crm/department/1/change/?_listfilter=None%3D return mark_safe("<a href='%s?%s'>%s</a>"%(self.config.get_change_url(pk),params.urlencode(),text)) def body_list(): #用于定制编辑列 if field_name in self.edit_link: val = self.edit_link_tag(row.pk,val)
4、=============重写get_list_display()方法================= 实现： # 重写get_list_display(),因为父类有这个方法，如果这里不写就会继承父类的，写了就优先执行自己的 def get_list_display(self): result = [] result.extend(self.list_display) result.insert(0,v1.StarkConfig.checkbox) result.append(v1.StarkConfig.edit) result.append(v1.StarkConfig.delete) return result 重写构造方法需要注意的： 函数和方法的区别：由于我们 val = field_name(self.config, row) ，传了一个self， 所以用第二种方式。用方式一就报错了 方式一：self.edit自己没有就找父类的，自己有就用自己的 方式二；v1.StarkConofig.edit 如果是函数自己写一个self =========写代码的时候注意加注释========================== 对类的注释 对于文件的注释 对于函数的注释
2、员工表
1、错误信息的显示
add_view
给errors加上个样式
2、自定义ModelForm def get_model_form_class(self): '''自定义ModelForm''' class MyModelForm(ModelForm): class Meta: model = models.UserInfo fields = "__all__" error_messages = { "name":{"required":"姓名不能为空"}, "username":{"required":"用户名不能为空"}, "password":{"required":"密码不能为空"}, "email":{"required":"邮箱不能为空","invalid":"邮箱格式不正确"}, "depart":{"required":"用户名不能不选",}, } return MyModelForm
3、组合搜索的筛选条件出错了:
组合搜索的筛选条件出错了: 出的错误：当你看到明明有数据，但是却没有查到 出错原因：是由于关联的字段变了depart = models.ForeignKey(verbose_name='部门', to="Department",to_field="code") 以前关联的是pk,现在关联的是code。所以对应的值就不一样了。所以找不到了 解决办法： 在FilterOption又加了两个参数 text_func_name ：组合搜素时，组合搜索时，页面上生成显示文本的函数 val_func_name ：组合搜素时，页面上生成a标签的value值的函数，也就是pk class FilterOption: def __init__(self, field_name, is_multi=False, is_choice=False, condition=None,text_func_name=None,val_func_name=None): self.text_func_name = text_func_name self.val_func_name = val_func_name # ================普通按钮==================== for val in self.data: #单选 if self.option.is_choice: # ((1,'男'),(2,'女'),(1,'男')) pk, text = str(val[0]),val[1] else: # 外键或多对多 '''现在的做法，是由于关联的字段变了depart = models.ForeignKey(verbose_name='部门', to="Department",to_field="code")''' text = str(self.option.text_func_name(val)) if self.option.text_func_name else str(val) pk = str(self.option.val_func_name(val)) if self.option.val_func_name else str(val.pk) #原来的做法 pk, text = str(val.pk), str(val) stark.py comb_filter = [ v1.FilterOption("depart",val_func_name=lambda x: x.code,), ]
stark.py
comb_filter = [ v1.FilterOption("depart",val_func_name=lambda x: x.code,), ] #分组搜索
3、班级管理
4、学校
5、课程
6、客户以及跟进记录
客户信息; 需求： 咨询课程 吧咨询课程以标签的形式显示 并且加样式一点击X就给删除了， 额外的增加个url def extra_url(self): ... 客户的状态。对于未报名的学生，有个跟进记录 跟进记录：一点跳转到详细的根进记录，这个根进记录的url 加上是否显示组合搜索。。。。。 自己可以查看自己的根进记录，不可以查看别人的（自己写一个视图函数 继承父类的方法， ）
代码实现
class ConsultRecordConfig(v1.StarkConfig): def customer_display(self,obj=None,is_header=False): if is_header: return "所咨询客户" return obj.customer.name list_display = [customer_display,"consultant","date","note"] comb_filter = [ v1.FilterOption("customer"), ] #组合搜索默认不显示，但是却又筛选的功能 def change_views(self, request,*args, **kwargs): customer = request.GET.get('customer') # session中获取当前用户ID current_login_user_id = 6 ct = models.Customer.objects.filter(consultant=current_login_user_id, id=customer).count() if not ct: return HttpResponse('无权访问.') return super(ConsultRecordConfig,self).change_views(request, *args, **kwargs) v1.site.register(models.ConsultRecord,ConsultRecordConfig) v1.py # =============组合搜索==================== comb_filter = [] def get_comb_filter(self): result = [] if self.comb_filter: result.extend(self.comb_filter) return result show_comb_filter = False def get_show_comb_filter(self): return self.show_comb_filter self.show_comb_filter = config.get_show_comb_filter() 在页面 {% if cl.show_comb_filter %} <div class="list-filter"> {% for item in cl.gen_comb_filter %} <div> {% for col in item %} {{ col }} {% endfor %} </div> {% endfor %} </div> {% endif %}
