# 处方用量功能完整实现总结
|
||||
|
||||
## 概述
|
||||
在两个处方页面中实现了用量、单位和代煎功能：
|
||||
1. **处方组件** (`admin/src/components/tcm-prescription/index.vue`) - 创建/编辑处方
|
||||
2. **处方列表** (`admin/src/views/consumer/prescription/index.vue`) - 查看/编辑处方
|
||||
|
||||
## 已实现的功能
|
||||
|
||||
### 1. 数据库层 ✅
|
||||
**文件**: `add_prescription_dosage_fields.sql`
|
||||
|
||||
```sql
|
||||
ALTER TABLE `zyt_tcm_prescription`
|
||||
ADD COLUMN `dosage_amount` decimal(10,2) DEFAULT NULL COMMENT '用量数值',
|
||||
ADD COLUMN `dosage_unit` varchar(10) NOT NULL DEFAULT '' COMMENT '用量单位(g/ml)',
|
||||
ADD COLUMN `need_decoction` tinyint(1) NOT NULL DEFAULT 0 COMMENT '是否代煎(0否1是,仅饮片)';
|
||||
```
|
||||
|
||||
### 2. 后端层 ✅
|
||||
|
||||
#### 模型 (`server/app/common/model/tcm/Prescription.php`)
|
||||
```php
|
||||
protected $type = [
|
||||
'dosage_amount' => 'float',
|
||||
'need_decoction' => 'integer',
|
||||
];
|
||||
```
|
||||
|
||||
#### 业务逻辑 (`server/app/adminapi/logic/tcm/PrescriptionLogic.php`)
|
||||
- ✅ `add()` 方法：保存新处方
|
||||
- ✅ `edit()` 方法：编辑处方
|
||||
|
||||
### 3. 前端层 ✅
|
||||
|
||||
#### 3.1 处方组件 (`admin/src/components/tcm-prescription/index.vue`)
|
||||
|
||||
**数据结构**:
|
||||
```typescript
|
||||
interface PrescriptionForm {
|
||||
prescription_type: string
|
||||
dosage_amount: number | undefined
|
||||
dosage_unit: string
|
||||
need_decoction: boolean
|
||||
// ...
|
||||
}
|
||||
```
|
||||
|
||||
**响应式数据**:
|
||||
```typescript
|
||||
const formData = reactive<PrescriptionForm>({
|
||||
prescription_type: '浓缩水丸',
|
||||
dosage_amount: 1,
|
||||
dosage_unit: 'g',
|
||||
need_decoction: false,
|
||||
// ...
|
||||
})
|
||||
```
|
||||
|
||||
**自动切换逻辑**:
|
||||
```typescript
|
||||
watch(() => formData.prescription_type, (newType) => {
|
||||
if (newType === '浓缩水丸') {
|
||||
formData.dosage_unit = 'g'
|
||||
formData.dosage_amount = 1
|
||||
formData.need_decoction = false
|
||||
} else if (newType === '饮片') {
|
||||
formData.dosage_unit = 'ml'
|
||||
formData.dosage_amount = 50
|
||||
} else {
|
||||
formData.dosage_unit = 'g'
|
||||
formData.dosage_amount = undefined
|
||||
formData.need_decoction = false
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
#### 3.2 处方列表 (`admin/src/views/consumer/prescription/index.vue`)
|
||||
|
||||
**数据结构**:
|
||||
```typescript
|
||||
const editForm = reactive({
|
||||
prescription_type: '浓缩水丸',
|
||||
dosage_amount: 1 as number | undefined,
|
||||
dosage_unit: 'g',
|
||||
need_decoction: false,
|
||||
// ...
|
||||
})
|
||||
```
|
||||
|
||||
**自动切换逻辑**:
|
||||
```typescript
|
||||
watch(() => editForm.prescription_type, (newType) => {
|
||||
if (newType === '浓缩水丸') {
|
||||
editForm.dosage_unit = 'g'
|
||||
editForm.dosage_amount = 1
|
||||
editForm.need_decoction = false
|
||||
} else if (newType === '饮片') {
|
||||
editForm.dosage_unit = 'ml'
|
||||
editForm.dosage_amount = 50
|
||||
} else {
|
||||
editForm.dosage_unit = 'g'
|
||||
editForm.dosage_amount = undefined
|
||||
editForm.need_decoction = false
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
## UI 组件实现
|
||||
|
||||
### 浓缩水丸 (1-10g)
|
||||
```vue
|
||||
<el-select v-model="formData.dosage_amount">
|
||||
<el-option label="1g" :value="1" />
|
||||
<el-option label="2g" :value="2" />
|
||||
<!-- ... 3-10g -->
|
||||
</el-select>
|
||||
```
|
||||
|
||||
### 饮片 (50-250ml)
|
||||
```vue
|
||||
<el-select v-model="formData.dosage_amount">
|
||||
<el-option label="50ml" :value="50" />
|
||||
<el-option label="100ml" :value="100" />
|
||||
<el-option label="150ml" :value="150" />
|
||||
<el-option label="200ml" :value="200" />
|
||||
<el-option label="250ml" :value="250" />
|
||||
</el-select>
|
||||
|
||||
<!-- 代煎选项 -->
|
||||
<el-radio-group v-model="formData.need_decoction">
|
||||
<el-radio :label="true">代煎</el-radio>
|
||||
<el-radio :label="false">不代煎</el-radio>
|
||||
</el-radio-group>
|
||||
```
|
||||
|
||||
### 其他类型
|
||||
```vue
|
||||
<el-input-number
|
||||
v-model="formData.dosage_amount"
|
||||
:min="0"
|
||||
:precision="2"
|
||||

|
||||
```
|
||||
|
||||
## 部署清单
|
||||
|
||||
### 1. 数据库迁移 ⚠️ 必须执行
|
||||
```bash
|
||||
mysql -u用户名 -p数据库名 < add_prescription_dosage_fields.sql
|
||||
```
|
||||
|
||||
### 2. 后端文件
|
||||
- ✅ `server/app/common/model/tcm/Prescription.php`
|
||||
- ✅ `server/app/adminapi/logic/tcm/PrescriptionLogic.php`
|
||||
|
||||
### 3. 前端文件
|
||||
- ✅ `admin/src/components/tcm-prescription/index.vue`
|
||||
- ✅ `admin/src/views/consumer/prescription/index.vue`
|
||||
|
||||
## 测试清单

|
||||
- [ ] 切换处方类型，验证用量自动调整
|
||||
- [ ] 保存处方，验证数据正确存储
|
||||
|
||||
### 处方列表测试
|
||||

- [ ] 查看处方详情，验证显示正确
|
||||
|
||||
### 数据验证测试
|
||||
- [ ] 浓缩水丸用量范围：1-10g
|
||||
- [ ] 饮片用量范围：50-250ml
|
||||
- [ ] 饮片用量步进：50ml
|
||||
- [ ] 代煎选项仅在饮片时显示
|
||||
- [ ] 切换类型时代煎选项自动隐藏
|
||||
|
||||
## 文件清单
|
||||
|
||||
### 数据库
|
||||
- `add_prescription_dosage_fields.sql` - 数据库迁移文件
|
||||
|
||||
### 后端
|
||||
- `server/app/common/model/tcm/Prescription.php` - 处方模型
|
||||
- `server/app/adminapi/logic/tcm/PrescriptionLogic.php` - 处方业务逻辑
|
||||
|
||||
### 前端
|
||||
- `admin/src/components/tcm-prescription/index.vue` - 处方组件
|
||||
- `admin/src/views/consumer/prescription/index.vue` - 处方列表
|
||||
|
||||
### 文档
|
||||
- `PRESCRIPTION_DOSAGE_FEATURE.md` - 功能说明
|
||||
- `PRESCRIPTION_DOSAGE_DATABASE_IMPLEMENTATION.md` - 数据库实现
|
||||
- `PRESCRIPTION_DOSAGE_COMPLETE_SUMMARY.md` - 本文档
|
||||
|
||||
## 注意事项
|
||||
|
||||
1. **数据库迁移必须先执行**，否则保存时会报错
|
||||
2. **旧数据兼容**：旧处方的用量字段为NULL，不影响显示
|
||||
3. **类型切换**：切换处方类型时，用量和单位会自动调整
|
||||
4. **代煎选项**：仅在选择"饮片"时显示
|
||||
5. **数据验证**：前端使用下拉选择确保数据有效性
|
||||
|
||||
## 后续优化建议
|
||||
|
||||
1. **后端验证**：添加用量范围的后端验证逻辑
|
||||
2. **打印显示**：在处方打印时显示用量和代煎信息
|
||||
3. **统计报表**：按处方类型和用量统计
|
||||
4. **价格联动**：根据用量自动计算处方价格
|
||||
5. **库存检查**：代煎选项关联药房库存
|
||||
|
||||
## 总结
|
||||
|
||||
✅ **数据库层**：3个字段已定义
|
||||
✅ **后端层**：模型和业务逻辑已实现
|
||||
✅ **前端层**：2个页面都已实现
|
||||
✅ **UI组件**：下拉选择器和单选按钮
|
||||
✅ **自动切换**：watch监听实现
|
||||
✅ **数据流转**：完整的保存和读取
|
||||
|
||||
**状态**: 功能完整实现，只需执行数据库迁移即可使用！🎉
