class StaffInfoAdmin(admin.ModelAdmin): inlines = [EmergencyInline, BackgroundInline, WorkInline, FamilyInline] search_fields = ['NAME', 'RES_ID'] list_display = ['NAME', 'BIRTH', 'RES_ID'] list_filter = ['POST'] def clean_fields(self, request, obj): mobile_pattern = re.compile(r'^1[3456789]\d{9}$') if not re.match(mobile_pattern, obj.TEL): raise ValidationError("请输入11位电话号码，且不包含'-'") super().clean_fields(request, obj)代码如上，但是没有完成合法性检查的功能，电话号码输入123依旧可以提交数据

根据你提供的代码，可以看出在`clean_fields`函数中进行了电话号码的合法性检查，但是这个函数并没有被调用。为了实现这个功能，你需要在`save_model`函数中手动调用`clean_fields`函数。修改后的代码如下：

class StaffInfoAdmin(admin.ModelAdmin):
    inlines = [EmergencyInline, BackgroundInline, WorkInline, FamilyInline]
    search_fields = ['NAME', 'RES_ID']
    list_display = ['NAME', 'BIRTH', 'RES_ID']
    list_filter = ['POST']
    
    def clean_fields(self, request, obj):
        mobile_pattern = re.compile(r'^1[3456789]\d{9}$')
        if not re.match(mobile_pattern, obj.TEL):
            raise ValidationError("请输入11位电话号码，且不包含'-'")
        super().clean_fields(request, obj)
        
    def save_model(self, request, obj, form, change):
        self.clean_fields(request, obj)
        super().save_model(request, obj, form, change)

这样就可以在保存数据之前进行合法性检查了。
