第二章 View的编写

前言

　　基于 ModelViewSet 来写各个试图, 编写逻辑按照Mode开始.

TableClassify

　　这个表就是前面将到的分类表, 也是整个项目的入口.

　　这个表基本上是比较简单的, 此表设计为二级表, 即有主分类, 主分类下才是真正实际应用的表.如下图

新增数据

　　新增数据主要关注 PID 字段, 如果上传 PID 则 PID 必须是存在的且它的 PID 为 Null.

11         return super(TableClassifyViewSet, self).create(request, *args, **kwargs)

修改数据

　　新增数据主要关注 PID 字段,

如果修改的数据为主类型, 则需要判断此表下有没有分类表, 如果有则禁止修改.
判断要修改的目标PID是否为主类型表, 判断方法, 取到 id = pid 的实例, 实例.pid 为空则是主分类.

13         return super(TableClassifyViewSet, self).update(request, *args, **kwargs)

表关系绑定

　　表关系绑定这里用到了 TableRelation 表来确定绑定管理,

字段说明:

TableClassify 的 is_forbid_bind, 这个值用来判断是否可以绑定, 如果设置为True, 其他的表就无法跟此表绑定.
TableRelation 的 parent_table, 主表ID.
TableRelation 的 child_table, 子表ID
TableRelation 的 is_foreign_key, 表示绑定之后数据的对应关系, 为True 则是一对多, 为 False 则是一对一.

验证逻辑:

验证上传的 parent_table_id 和 child_table_id 是否存在 TableClassify 实例. 并且不是主分类表.
验证 parent_table_id 和 child_table_id 实例 is_forbid_bind 如果为 True 则禁止进行数据绑定.
验证 parent_table_id 和 child_table_id 实例有没有自己的字段表, 如果没有禁止绑定, 这个规则可以删掉, 逻辑问题.

验证逻辑
- 确定存在绑定记录
- 清理资产绑定记录
- child_table is_forbid_bind 字段如果为True 修改为False.

无试图代码, serializers 代码如下

class TableClassifySerializer(serializers.ModelSerializer):
    class Meta:
        model = TableClassify
        fields = '__all__'

    def to_representation(self, instance):
        representation = super(TableClassifySerializer, self).to_representation(instance)
        representation['fields'] = TableFieldSerializer(instance.fields).data['fields'] if hasattr(instance,
                                                                                                   'fields') else None
        representation['rules'] = TableFieldSerializer(instance.fields).data['rules'] if hasattr(instance,
                                                                                                 'fields') else None
        return representation

TableField

　　字段表, 主要用于类型表的字段存储, 以及校验规则.

字段说明:

fields 字段

 1 "fields": {
 2     "hostname": {
 3         "name": "主机名",      # key 字段, val 是中文, 前端展示以及后端校验使用. 
 4         "guid": true,          # 全局唯一, 用来标识唯一Key的. 只可以出现一次
 5         "order": 0               # 排序 ID, 前端使用
 6     },
 7     "manage_ip": {
 8         "name": "管理IP",
 9         "order": 1
10     }
11     ... 
12 }

rules

 1 "rules": {
 2     "hostname": {               # key 跟 fields 字段 key 一一对应.
 3         "type": "Str",
 4         "lens": 46,                # 限制属性可选
 5         "unique": true,            # 如果 fields 中设置了全局唯一 key.必须这是 unique 为 True
 6         "not_null": false
 7     },
 8     "manage_ip": {
 9         "type": "IP",
10         "unique": true,
11         "prefix": "172.16.0."
12     }
13     ...
14 }

现支持的类型及属性:

类型
- ```
["Str", "Int", "Choice", "IP"]
```

属性

["default", "unique", "not_null", "lens", "choice", "prefix", "max", "min"]

新增数据

验证逻辑
- 1. 如果分类表是主分类表禁止绑定.
- 2. 上传数据验证, 使用 check_fields

数据绑定

验证逻辑
- 验证有没有分类关系表为 parent_table_id 和 child_table_id
- 判断分类表有没有响应的资产数据, 即查询条件 table_classify_id = parent_table_id & id = parent_asset_id
- 如果关系绑定实例的 is_foreign_key == False, 需要判断子资产有没有被其他资产绑定过.
