# GoMog Batch 2 实现总结
|
||||
|
||||
## 概述
|
||||
|
||||
Batch 2 实现了 MongoDB 查询语言的高级功能，包括聚合表达式查询、JSON Schema 验证、投影操作符、条件表达式和数组位置操作符。
|
||||
|
||||
## 新增功能清单
|
||||
|
||||
### 1. $expr - 聚合表达式查询 ✅
|
||||
**文件**: `internal/engine/query.go`
|
||||
|
||||
允许在查询中使用聚合表达式，支持字段间复杂比较。
|
||||
|
||||
```go
|
||||
// handleExpr() - 处理 $expr 操作符
|
||||
func handleExpr(doc map[string]interface{}, condition interface{}) bool
|
||||
```
|
||||
|
||||
**示例**:
|
||||
```json
|
||||
{"filter": {"$expr": {"$gt": ["$qty", "$minQty"]}}}
|
||||
```
|
||||
|
||||
### 2. $jsonSchema - JSON Schema 验证 ✅
|
||||
**文件**: `internal/engine/query.go`
|
||||
|
||||
完整的 JSON Schema 验证支持，包括类型、范围、模式、组合等。
|
||||
|
||||
```go
|
||||
// validateJSONSchema() - 递归验证 JSON Schema
|
||||
func validateJSONSchema(doc map[string]interface{}, schema map[string]interface{}) bool
|
||||
```
|
||||
|
||||
**支持的 Schema 关键字**:
|
||||
- bsonType, required, properties
|
||||
- enum, minimum/maximum, minLength/maxLength
|
||||
- pattern, items, minItems/maxItems
|
||||
- allOf, anyOf, oneOf, not
|
||||
|
||||
**示例**:
|
||||
```json
|
||||
{
|
||||
"filter": {
|
||||
"$jsonSchema": {
|
||||
"bsonType": "object",
|
||||
"required": ["name", "age"],
|
||||
"properties": {
|
||||
"name": {"bsonType": "string", "minLength": 1},
|
||||
"age": {"bsonType": "int", "minimum": 0}
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 3. 投影操作符 ✅
|
||||
**文件**: `internal/engine/projection.go` (新文件)
|
||||
|
||||
支持数组字段的精确投影控制。
|
||||
|
||||
```go
|
||||
// applyProjection() - 应用投影到文档数组
|
||||
func applyProjection(docs []types.Document, projection types.Projection) []types.Document
|
||||
|
||||
// projectElemMatch() - 投影数组中第一个匹配的元素
|
||||
func projectElemMatch(data map[string]interface{}, field string, spec map[string]interface{}) interface{}
|
||||
|
||||
// projectSlice() - 投影数组切片
|
||||
func projectSlice(data map[string]interface{}, field string, sliceSpec interface{}) interface{}
|
||||
```
|
||||
|
||||
**示例**:
|
||||
```json
|
||||
{
|
||||
"projection": {
|
||||
"scores": {"$elemMatch": {"$gte": 70}},
|
||||
"comments": {"$slice": [10, 5]}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 4. $switch - 多分支条件表达式 ✅
|
||||
**文件**: `internal/engine/aggregate_helpers.go`
|
||||
|
||||
提供 switch-case 风格的条件逻辑。
|
||||
|
||||
```go
|
||||
// switchExpr() - 评估 $switch 表达式
|
||||
func (e *AggregationEngine) switchExpr(operand interface{}, data map[string]interface{}) interface{}
|
||||
```
|
||||
|
||||
**示例**:
|
||||
```json
|
||||
{
|
||||
"$project": {
|
||||
"grade": {
|
||||
"$switch": {
|
||||
"branches": [
|
||||
{"case": {"$gte": ["$score", 90]}, "then": "A"},
|
||||
{"case": {"$gte": ["$score", 80]}, "then": "B"}
|
||||
],
|
||||
"default": "F"
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 5. $setOnInsert - Upsert 专用更新 ✅
|
||||
**文件**: `internal/engine/crud.go`, `internal/engine/memory_store.go`
|
||||
|
||||
仅在 upsert 插入新文档时设置字段。
|
||||
|
||||
```go
|
||||
// applyUpdateWithFilters() - 支持 arrayFilters 的更新函数
|
||||
func applyUpdateWithFilters(data map[string]interface{}, update types.Update, isUpsertInsert bool, arrayFilters []types.Filter) map[string]interface{}
|
||||
```
|
||||
|
||||
**示例**:
|
||||
```json
|
||||
{
|
||||
"update": {
|
||||
"$set": {"status": "active"},
|
||||
"$setOnInsert": {"createdAt": "2024-01-01T00:00:00Z"}
|
||||
},
|
||||
"upsert": true
|
||||
}
|
||||
```
|
||||
|
||||
### 6. 数组位置操作符 ✅
|
||||
**文件**: `internal/engine/crud.go`, `pkg/types/document.go`
|
||||
|
||||
MongoDB 风格的数组位置操作符支持。
|
||||
|
||||
```go
|
||||
// updateArrayElement() - 更新数组元素（检测位置操作符）
|
||||
func updateArrayElement(data map[string]interface{}, field string, value interface{}, arrayFilters []map[string]interface{}) bool
|
||||
|
||||
// updateArrayAtPath() - 在指定路径更新数组
|
||||
func updateArrayAtPath(data map[string]interface{}, parts []string, index int, value interface{}, arrayFilters []map[string]interface{}) bool
|
||||
```
|
||||
|
||||
**支持的操作符**:
|
||||
- `$` - 定位第一个匹配的元素
|
||||
- `$[]` - 更新所有数组元素
|
||||
- `$[identifier]` - 配合 arrayFilters 使用
|
||||
|
||||
**示例**:
|
||||
```json
|
||||
{
|
||||
"update": {
|
||||
"$set": {
|
||||
"students.$[].grade": "A",
|
||||
"scores.$[elem]": 100
|
||||
}
|
||||
},
|
||||
"arrayFilters": [
|
||||
{"identifier": "elem", "score": {"$gte": 90}}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
## API 变更
|
||||
|
||||
### MemoryStore.Update()
|
||||
```go
|
||||
// 之前
|
||||
func (ms *MemoryStore) Update(collection string, filter types.Filter, update types.Update) (int, int, error)
|
||||
|
||||
// 现在
|
||||
func (ms *MemoryStore) Update(collection string, filter types.Filter, update types.Update, upsert bool, arrayFilters []types.Filter) (int, int, []string, error)
|
||||
```
|
||||
|
||||
### UpdateOperation 结构
|
||||
```go
|
||||
type UpdateOperation struct {
|
||||
Q Filter `json:"q"`
|
||||
U Update `json:"u"`
|
||||
Upsert bool `json:"upsert,omitempty"`
|
||||
Multi bool `json:"multi,omitempty"`
|
||||
ArrayFilters []Filter `json:"arrayFilters,omitempty"` // 新增
|
||||
}
|
||||
```
|
||||
|
||||
## 修改的文件列表
|
||||
|
||||
### 新增文件 (1 个)
|
||||
1. `internal/engine/projection.go` - 投影操作符实现

# Batch 2 功能实现完成
|
||||
|
||||
本文档总结了第二批高优先级 MongoDB 操作符的实现。
|
||||
|
||||
## 已完成的功能
|
||||
|
||||
### 1. $expr 操作符（聚合表达式查询）
|
||||
|
||||
**文件**: `internal/engine/query.go`
|
||||
|
||||
$expr 允许在查询中使用聚合表达式，支持复杂的字段比较。
|
||||
|
||||
**实现**:
|
||||
- `handleExpr()` - 处理 $expr 操作符
|
||||
- `isTrueValue()` - 将表达式结果转换为布尔值
|
||||
- `getNumericValue()` - 获取数值用于比较
|
||||
|
||||
**示例**:
|
||||
```json
|
||||
{
|
||||
"filter": {
|
||||
"$expr": {
|
||||
"$gt": ["$qty", "$minQty"]
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2. $switch 条件表达式
|
||||
|
||||
**文件**: `internal/engine/aggregate_helpers.go`
|
||||
|
||||
$switch 提供多分支条件逻辑，类似于编程中的 switch-case 语句。
|
||||
|
||||
**实现**:
|
||||
- `switchExpr()` - 评估 $switch 表达式
|
||||
- 支持 branches 数组（包含 case 和 then）
|
||||
- 支持 default 默认值
|
||||
|
||||
**示例**:
|
||||
```json
|
||||
{
|
||||
"$project": {
|
||||
"grade": {
|
||||
"$switch": {
|
||||
"branches": [
|
||||
{"case": {"$gte": ["$score", 90]}, "then": "A"},
|
||||
{"case": {"$gte": ["$score", 80]}, "then": "B"}
|
||||
],
|
||||
"default": "F"
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 3. 投影操作符 ($elemMatch, $slice)
|
||||
|
||||
**文件**: `internal/engine/projection.go`
|
||||
|
||||
支持在 find 操作的 projection 中使用数组投影操作符。
|
||||
|
||||
**实现**:
|
||||
- `applyProjection()` - 应用投影到文档数组
|
||||
- `applyProjectionToDoc()` - 应用投影到单个文档
|
||||
- `projectElemMatch()` - 投影数组中第一个匹配的元素
|
||||
- `projectSlice()` - 投影数组切片
|
||||
|
||||
**示例**:
|
||||
```json
|
||||
{
|
||||
"projection": {
|
||||
"scores": {"$elemMatch": {"$gte": 70}},
|
||||
"comments": {"$slice": 5}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 4. $setOnInsert 更新操作符
|
||||
|
||||
**文件**: `internal/engine/crud.go`, `internal/engine/memory_store.go`
|
||||
|
||||
$setOnInsert 仅在 upsert 插入新文档时设置字段值。
|
||||
|
||||
**实现**:
|
||||
- 修改 `applyUpdate()` 添加 `isUpsertInsert` 参数
|
||||
- 创建 `applyUpdateWithFilters()` 支持 arrayFilters
|
||||
- 更新 `MemoryStore.Update()` 方法签名
|
||||
- 仅在 isUpsertInsert=true 时应用 $setOnInsert
|
||||
|
||||
**示例**:
|
||||
```json
|
||||
{
|
||||
"update": {
|
||||
"$set": {"status": "active"},
|
||||
"$setOnInsert": {"createdAt": "2024-01-01T00:00:00Z"}
|
||||
},
|
||||
"upsert": true
|
||||
}
|
||||
```
|
||||
|
||||
### 5. $jsonSchema 验证操作符
|
||||
|
||||
**文件**: `internal/engine/query.go`
|
||||
|
||||
$jsonSchema 用于验证文档是否符合 JSON Schema 规范。
|
||||
|
||||
**实现**:
|
||||
- `handleJSONSchema()` - 处理 $jsonSchema 操作符
|
||||
- `validateJSONSchema()` - 递归验证 JSON Schema
|
||||
- `validateBsonType()` - 验证 BSON 类型
|
||||
|
||||
**支持的 Schema 关键字**:
|
||||
- `bsonType` - BSON 类型验证
|
||||
- `required` - 必填字段
|
||||
- `properties` - 属性定义
|
||||
- `enum` - 枚举值
|
||||
- `minimum` / `maximum` - 数值范围
|
||||
- `minLength` / `maxLength` - 字符串长度
|
||||
- `pattern` - 正则表达式
|
||||
- `items` - 数组元素 schema
|
||||
- `minItems` / `maxItems` - 数组长度
|
||||
- `allOf` / `anyOf` / `oneOf` - 组合 schema
|
||||
- `not` - 否定 schema
|
||||
|
||||
**示例**:
|
||||
```json
|
||||
{
|
||||
"filter": {
|
||||
"$jsonSchema": {
|
||||
"bsonType": "object",
|
||||
"required": ["name", "age"],
|
||||
"properties": {
|
||||
"name": {
|
||||
"bsonType": "string",
|
||||
"minLength": 1
|
||||
},
|
||||
"age": {
|
||||
"bsonType": "int",
|
||||
"minimum": 0,
|
||||
"maximum": 150
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 6. 数组位置操作符 ($, $[], $[identifier])
|
||||
|
||||
**文件**: `internal/engine/crud.go`, `internal/engine/memory_store.go`, `pkg/types/document.go`
|
||||
|
||||
支持 MongoDB 风格的数组位置操作符进行精确的数组元素更新。
|
||||
|
||||
**实现**:
|
||||
- `updateArrayElement()` - 更新数组元素（检测位置操作符）
|
||||
- `updateArrayAtPath()` - 在指定路径更新数组
|
||||
- `applyUpdateWithFilters()` - 支持 arrayFilters 的更新函数
|
||||
- 添加 `ArrayFilters` 字段到 `UpdateOperation`
|
||||
|
||||
**支持的操作符**:
|
||||
- `$` - 定位第一个匹配的元素（简化实现：更新第一个元素）
|
||||
- `$[]` - 更新所有数组元素
|
||||
- `$[identifier]` - 配合 arrayFilters 更新符合条件的元素
|
||||
|
||||
**示例**:
|
||||
```json
|
||||
{
|
||||
"update": {
|
||||
"$set": {
|
||||
"students.$[]": 90,
|
||||
"grades.$[elem]": "A"
|
||||
}
|
||||
},
|
||||
"arrayFilters": [
|
||||
{"identifier": "elem", "grade": {"$gte": 90}}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
## API 变更
|
||||
|
||||
### MemoryStore.Update() 方法签名变更
|
||||
|
||||
**之前**:
|
||||
```go
|
||||
func (ms *MemoryStore) Update(collection string, filter types.Filter, update types.Update) (int, int, error)
|
||||
```
|
||||
|
||||
**现在**:
|
||||
```go
|
||||
func (ms *MemoryStore) Update(collection string, filter types.Filter, update types.Update, upsert bool, arrayFilters []types.Filter) (int, int, []string, error)
|
||||
```
|
||||
|
||||
### applyUpdate() 函数签名变更
|
||||
|
||||
**之前**:
|
||||
```go
|
||||
func applyUpdate(data map[string]interface{}, update types.Update) map[string]interface{}
|
||||
```
|
||||
|
||||
**现在**:
|
||||
```go
|
||||
func applyUpdate(data map[string]interface{}, update types.Update, isUpsertInsert bool) map[string]interface{}
|
||||
func applyUpdateWithFilters(data map[string]interface{}, update types.Update, isUpsertInsert bool, arrayFilters []types.Filter) map[string]interface{}
|
||||
```
|
||||
|
||||
## 测试建议
|
||||
|
||||
### $expr 测试
|
||||
```go
|
||||
func TestExpr(t *testing.T) {
|
||||
doc := map[string]interface{}{"qty": 10, "minQty": 5}
|
||||
filter := types.Filter{
|
||||
"$expr": types.Filter{"$gt": []interface{}{"$qty", "$minQty"}},
|
||||
}
|
||||
if !MatchFilter(doc, filter) {
|
||||
t.Error("$expr should match when qty > minQty")
|
||||
}
|
