## 使用示例
### JavaScript (Fetch API)
```javascript
async function createParameter(paramData) {
const response = await fetch('/api/v1/parameters/', {
method: 'POST',
headers: {
'Authorization': `Bearer ${token}`,
'Content-Type': 'application/json'
},
body: JSON.stringify({
key: paramData.key,
value: paramData.value,
description: paramData.description,
is_required: paramData.isRequired || false,
is_image_path: paramData.isImagePath || false
})
});
if (!response.ok) {
const error = await response.json();
if (error.key) {
throw new Error('参数键已存在，请使用其他名称');
}
throw new Error('创建失败');
}
return await response.json();
}
// 使用示例
try {
const newParam = await createParameter({
key: 'fabric_color',
value: '红色',
description: '面料颜色',
isRequired: true,
isImagePath: false
});
console.log('创建成功:', newParam);
} catch (error) {
console.error('创建失败:', error.message);
}
```
### JavaScript (Axios)
```javascript
import axios from 'axios';
async function createParameter(paramData) {
try {
const response = await axios.post('/api/v1/parameters/', {
key: paramData.key,
value: paramData.value,
description: paramData.description,
is_required: paramData.isRequired || false,
is_image_path: paramData.isImagePath || false
}, {
headers: {
'Authorization': `Bearer ${token}`
}
});
return response.data;
} catch (error) {
if (error.response?.data?.key) {
throw new Error('参数键已存在');
}
throw error;
}
}
```
### Python (requests)
```python
import requests
def create_parameter(token, key, value=None, description='', is_required=False, is_image_path=False):
url = 'https://your-domain.com/api/v1/parameters/'
headers = {
'Authorization': f'Bearer {token}',
'Content-Type': 'application/json'
}
data = {
'key': key,
'value': value,
'description': description,
'is_required': is_required,
'is_image_path': is_image_path
}
response = requests.post(url, json=data, headers=headers)
if response.status_code == 201:
return response.json()
elif response.status_code == 400:
error = response.json()
if 'key' in error:
raise ValueError('参数键已存在')
raise ValueError(f'创建失败: {error}')
else:
response.raise_for_status()
# 使用示例
try:
new_param = create_parameter(
token='your_jwt_token',
key='fabric_weight',
value='300g/m²',
description='面料克重',
is_required=True
)
print(f'创建成功: {new_param}')
except ValueError as e:
print(f'错误: {e}')
```
### cURL
```bash
# 基本创建
curl -X POST https://your-domain.com/api/v1/parameters/ \
-H "Authorization: Bearer your_jwt_token" \
-H "Content-Type: application/json" \
-d '{
"key": "print_method",
"value": "丝网印刷",
"description": "印刷方式",
"is_required": true,
"is_image_path": false
}'
# 最小请求（只创建 key）
curl -X POST https://your-domain.com/api/v1/parameters/ \
-H "Authorization: Bearer your_jwt_token" \
-H "Content-Type: application/json" \
-d '{"key": "simple_param"}'
```
---
## 常见使用场景
### 场景1：创建普通文本参数
```javascript
const textParam = await createParameter({
key: 'fabric_type',
value: '纯棉',
description: '面料类型',
isRequired: true,
isImagePath: false
});
```
### 场景2：创建图片路径参数
```javascript
const imageParam = await createParameter({
key: 'design_preview',
value: '/uploads/designs/preview_001.jpg',
description: '设计预览图',
isRequired: false,
isImagePath: true // 标记为图片路径
});
```
### 场景3：创建必填参数（用于流程验证）
```javascript
const requiredParam = await createParameter({
key: 'customer_approval',
value: '待确认',
description: '客户审批状态',
isRequired: true, // 标记为必填
isImagePath: false
});
```
### 场景4：批量创建参数
```javascript
const paramsToCreate = [
{ key: 'color', description: '颜色' },
{ key: 'size', description: '尺寸' },
{ key: 'quantity', description: '数量' }
];
const results = await Promise.all(
paramsToCreate.map(param => createParameter(param))
);
console.log('批量创建完成:', results);
```
---
## 注意事项
1. ⚠️ **key 必须唯一**：如果 key 已存在，会返回 400 错误，创建前可以先查询是否存在
2. 📝 **value 可为空**：value 字段是可选的，可以先创建参数，后续再更新值
3. 🔐 **必须认证**：请求头必须包含有效的 JWT Token
4. 🏷️ **is_image_path 标记**：如果 value 存储的是图片路径，建议设置 `is_image_path: true` 以便前端正确处理
5. ✅ **is_required 标记**：用于标识该参数在业务流程中是否为必填项，方便表单验证
---
## 与其他接口的配合使用
### 创建后查询详情
```javascript
// 1. 创建参数
const newParam = await createParameter({
key: 'logo_position',
description: 'Logo位置'
});
// 2. 查询详情
const detail = await fetch(`/api/v1/parameters/${newParam.id}/`, {
headers: { 'Authorization': `Bearer ${token}` }
}).then(r => r.json());
```
### 创建后立即更新
```javascript
// 1. 先创建
const param = await createParameter({
key: 'temp_param'
});
// 2. 立即更新值
const updated = await fetch(`/api/v1/parameters/${param.id}/`, {
method: 'PATCH',
headers: {
'Authorization': `Bearer ${token}`,
'Content-Type': 'application/json'
},
body: JSON.stringify({
value: '最终值',
description: '更新后的描述'
})
}).then(r => r.json());
```
---
## 测试状态
✅ 所有相关测试用例已通过：
- 创建普通参数
- 创建最小参数（仅 key）
- 重复 key 验证
- 字段验证
- 认证验证
接口已可用于生产环境。

# Products API 文档
## 概述
Products API 提供轻量级的产品查询接口，专门为前端下拉框和自动完成功能设计。
**特点**:
- 只返回 `id` 和 `name` 字段，减少数据传输
- 支持分页（LimitOffset）
- 支持按名称模糊搜索
- 需要 JWT 认证
**基础路径**: `/api/v1/products/quick/`
---
## 认证
所有接口都需要 JWT 认证。在请求头中添加：
```
Authorization: Bearer <access_token>
```
---
## 接口详情
### 获取产品列表
**请求**
```
GET /api/v1/products/quick/
```
**查询参数**
| 参数 | 类型 | 必填 | 说明 |
|------|------|------|------|
| limit | integer | 否 | 返回结果数量，不提供则返回所有 |
| offset | integer | 否 | 偏移量，默认 0 |
| search | string | 否 | 按产品名称模糊搜索（不区分大小写） |
**请求示例**
```bash
# 获取所有产品
curl -X GET "http://localhost:8000/api/v1/products/quick/" \
-H "Authorization: Bearer YOUR_TOKEN"
# 分页获取（前10条）
curl -X GET "http://localhost:8000/api/v1/products/quick/?limit=10&offset=0" \
-H "Authorization: Bearer YOUR_TOKEN"
# 按名称搜索
curl -X GET "http://localhost:8000/api/v1/products/quick/?search=布料" \
-H "Authorization: Bearer YOUR_TOKEN"
# 搜索 + 分页
curl -X GET "http://localhost:8000/api/v1/products/quick/?search=布料&limit=5&offset=0" \
-H "Authorization: Bearer YOUR_TOKEN"
```
**成功响应 - 不分页** (200 OK)
```json
{
"count": 5,
"results": [
{
"id": 1,
"name": "纯棉布料"
},
{
"id": 2,
"name": "涤纶布料"
},
{
"id": 3,
"name": "丝绸布料"
},
{
"id": 4,
"name": "麻布"
},
{
"id": 5,
"name": "牛仔布"
}
]
}
```
**成功响应 - 带分页** (200 OK)
```json
{
"count": 50,
"next": "http://localhost:8000/api/v1/products/quick/?limit=10&offset=10",
"previous": null,
"results": [
{
"id": 1,
"name": "纯棉布料"
},
{
"id": 2,
"name": "涤纶布料"
}
]
}
```
**错误响应**
| 状态码 | 说明 |
|--------|------|
| 401 Unauthorized | 未认证或 Token 无效 |
| 403 Forbidden | 无权限访问 |
```json
{
"detail": "Authentication credentials were not provided."
}
```
---
## 使用场景
### 1. 前端下拉框
```javascript
// React 示例
import { useState, useEffect } from 'react';
function ProductSelect() {
const [products, setProducts] = useState([]);
const [loading, setLoading] = useState(false);
useEffect(() => {
const fetchProducts = async () => {
setLoading(true);
const response = await fetch('/api/v1/products/quick/?limit=100', {
headers: {
'Authorization': `Bearer ${token}`
}
});
const data = await response.json();
setProducts(data.results);
setLoading(false);
};
fetchProducts();
}, []);
return (
<select>
{products.map(product => (
<option key={product.id} value={product.id}>
{product.name}
</option>
))}
</select>
);
}
```
### 2. 自动完成（Autocomplete）
```javascript
// Vue 3 + Element Plus 示例
<template>
<el-autocomplete
v-model="searchText"
:fetch-suggestions="queryProducts"
placeholder="搜索产品"
@select="handleSelect"
/>
</template>
<script setup>
import { ref } from 'vue';
const searchText = ref('');
const queryProducts = async (queryString, cb) => {
const url = queryString
? `/api/v1/products/quick/?search=${encodeURIComponent(queryString)}&limit=10`
: '/api/v1/products/quick/?limit=10';
const response = await fetch(url, {
headers: {
'Authorization': `Bearer ${token}`
}
});
const data = await response.json();
// 转换为 Element Plus 需要的格式
const suggestions = data.results.map(p => ({
value: p.name,
id: p.id
}));
cb(suggestions);
};
const handleSelect = (item) => {
console.log('选中产品:', item.id, item.value);
};
</script>
```
### 3. 搜索框实时搜索
```javascript
// Vanilla JavaScript 示例
const searchInput = document.getElementById('product-search');
const resultsContainer = document.getElementById('search-results');
let debounceTimer;
searchInput.addEventListener('input', (e) => {
clearTimeout(debounceTimer);
debounceTimer = setTimeout(async () => {
const searchText = e.target.value.trim();
if (searchText.length < 2) {
resultsContainer.innerHTML = '';
return;
}
const response = await fetch(
`/api/v1/products/quick/?search=${encodeURIComponent(searchText)}&limit=10`,
{
headers: {
'Authorization': `Bearer ${token}`
}
}
);
const data = await response.json();
// 渲染搜索结果
resultsContainer.innerHTML = data.results.map(product => `
<div class="search-result" data-id="${product.id}">
${product.name}
</div>
`).join('');
}, 300); // 300ms 防抖
});
```
---
## Python 使用示例
### 基础查询
```python
import requests
BASE_URL = "http://localhost:8000"
TOKEN = "your_jwt_token"
headers = {"Authorization": f"Bearer {TOKEN}"}
# 获取所有产品
response = requests.get(f"{BASE_URL}/api/v1/products/quick/", headers=headers)
products = response.json()
print(f"共有 {products['count']} 个产品:")
for product in products['results']:
print(f" - {product['id']}: {product['name']}")
```
### 分页查询
```python
def get_all_products(token):
"""获取所有产品（自动处理分页）"""
BASE_URL = "http://localhost:8000"
headers = {"Authorization": f"Bearer {token}"}
all_products = []
offset = 0
limit = 50
while True:
response = requests.get(
f"{BASE_URL}/api/v1/products/quick/?limit={limit}&offset={offset}",
headers=headers
)
data = response.json()
all_products.extend(data['results'])
if data['next'] is None:
break
offset += limit
return all_products
# 使用
products = get_all_products(token)
print(f"总共获取了 {len(products)} 个产品")
```
### 搜索查询
```python
def search_products(token, query, limit=10):
"""搜索产品"""
BASE_URL = "http://localhost:8000"
headers = {"Authorization": f"Bearer {token}"}
response = requests.get(
f"{BASE_URL}/api/v1/products/quick/?search={query}&limit={limit}",
headers=headers
)
return response.json()['results']
# 使用
results = search_products(token, "布料", limit=5)
for product in results:
print(f"{product['id']}: {product['name']}")
```
---
## 性能优化建议
### 前端缓存
```javascript
// 使用本地缓存避免重复请求
class ProductCache {
constructor() {
this.cache = new Map();
this.cacheTimeout = 5 * 60 * 1000; // 5分钟
}
async getProducts(search = '', limit = 100) {
const cacheKey = `${search}:${limit}`;
const cached = this.cache.get(cacheKey);
if (cached && Date.now() - cached.timestamp < this.cacheTimeout) {
return cached.data;
}
const url = search
? `/api/v1/products/quick/?search=${encodeURIComponent(search)}&limit=${limit}`
: `/api/v1/products/quick/?limit=${limit}`;
const response = await fetch(url, {
headers: {
'Authorization': `Bearer ${token}`
}
});
const data = await response.json();
this.cache.set(cacheKey, {
data: data.results,
timestamp: Date.now()
});
return data.results;
}
clear() {
this.cache.clear();
}
}
const productCache = new ProductCache();
```
### 防抖搜索
```javascript
// 防抖函数避免频繁请求
function debounce(func, wait) {
let timeout;
return function executedFunction(...args) {
const later = () => {
clearTimeout(timeout);
func(...args);
};
clearTimeout(timeout);
timeout = setTimeout(later, wait);
};
}
const searchProducts = debounce(async (query) => {
const response = await fetch(
`/api/v1/products/quick/?search=${encodeURIComponent(query)}&limit=10`,
{
headers: {
'Authorization': `Bearer ${token}`
}
}
);
const data = await response.json();
updateSearchResults(data.results);
}, 300);
```
---
## 常见问题
### Q: 为什么只返回 id 和 name？
**A**: 这是一个轻量级接口，专门为下拉框和自动完成设计。只返回必要的字段可以：
- 减少数据传输量
- 提高响应速度
- 降低服务器负载
如果需要完整的产品信息，请使用完整的产品 API。
### Q: 搜索是否区分大小写？
**A**: 不区分。搜索使用 `icontains` 查询，对大小写不敏感。
### Q: 最多能返回多少条数据？
**A**: 建议使用 `limit` 参数限制返回数量。对于下拉框，建议 `limit=100`；对于自动完成，建议 `limit=10`。
### Q: 如何实现"加载更多"功能？
**A**: 使用 `offset` 参数进行分页。每次增加 `offset` 的值来获取下一页数据。
```javascript
let offset = 0;
const limit = 20;
async function loadMore() {
const response = await fetch(
`/api/v1/products/quick/?limit=${limit}&offset=${offset}`,
{ headers: { 'Authorization': `Bearer ${token}` } }
);
const data = await response.json();
appendProducts(data.results);
offset += limit;
// 检查是否还有更多数据
return data.next !== null;
}
```

## 测试
完整的测试套件位于 `api_v1/views/products/test_products_api.py`。
运行测试：
```bash
# 运行所有产品 API 测试
python manage.py test api_v1.views.products
# 运行特定测试
python manage.py test api_v1.views.products.test_products_api.ProductQuickAPITestCase.test_search_products_by_name
```
测试覆盖：
- ✅ 基础列表查询（带/不带分页）
- ✅ 名称模糊搜索
- ✅ 搜索 + 分页组合
- ✅ 大小写不敏感搜索
- ✅ 空结果处理
- ✅ 认证检查
- ✅ 响应格式验证

# Products API 模块总结
## 概述
为 `api_v1` 创建了独立的 `products` 模块，提供轻量级产品查询接口，专门为前端下拉框和自动完成功能设计。
**完成日期**: 2025-11-18
---
## 模块结构
```
api_v1/views/products/
├── __init__.py # 模块导出
├── views.py # ProductQuickViewSet
├── test_products_api.py # API 测试（11个测试）
└── API.md # 完整API文档
```
---
## 功能特性
### 1. 轻量级接口
- 只返回 `id` 和 `name` 两个字段
- 减少数据传输，提升响应速度
- 专为前端组件优化
### 2. 分页支持
- 使用 LimitOffsetPagination
- 支持 `limit` 和 `offset` 参数
- 不提供 `limit` 时返回所有结果
### 3. 模糊搜索
- 支持按产品名称搜索（`search` 参数）
- 大小写不敏感
- 支持部分匹配
### 4. 认证保护
- 需要 JWT Token 认证
- 使用 `IsAuthenticated` 权限类
---
## API 端点
**URL**: `GET /api/v1/products/quick/`
**查询参数**:
| 参数 | 类型 | 必填 | 说明 |
|------|------|------|------|
| limit | integer | 否 | 返回结果数量 |
| offset | integer | 否 | 偏移量，默认 0 |
| search | string | 否 | 按产品名称模糊搜索 |
**响应格式**:
```json
{
"count": 5,
"results": [
{"id": 1, "name": "纯棉布料"},
{"id": 2, "name": "涤纶布料"}
]
}
```
带分页时增加 `next` 和 `previous` 字段。
---
## 测试覆盖
**测试文件**: `api_v1/views/products/test_products_api.py`
**测试数量**: 11 个
**测试项**:
1. ✅ `test_list_products_without_pagination` - 无分页列表
2. ✅ `test_list_products_with_pagination` - 带分页列表
3. ✅ `test_search_products_by_name` - 按名称搜索
4. ✅ `test_search_products_by_partial_name` - 部分名称搜索
5. ✅ `test_search_with_pagination` - 搜索+分页组合
6. ✅ `test_search_no_results` - 无搜索结果
7. ✅ `test_unauthorized_access` - 未认证访问
8. ✅ `test_response_format` - 响应格式验证
9. ✅ `test_empty_database` - 空数据库处理
10. ✅ `test_case_insensitive_search` - 大小写不敏感搜索
11. ✅ `test_pagination_edge_cases` - 分页边界情况
**运行测试**:
```bash
python manage.py test api_v1.views.products.test_products_api
```
**测试结果**: ✅ 11/11 passed
---
## 代码实现
### ViewSet 实现
```python
class ProductQuickViewSet(viewsets.GenericViewSet):
"""产品快速查询接口"""
queryset = Product.objects.all()
permission_classes = [IsAuthenticated]
pagination_class = LimitOffsetPagination
filter_backends = [DjangoFilterBackend, filters.SearchFilter]
search_fields = ['name']
def list(self, request, *args, **kwargs):
# 只返回 id 和 name
queryset = self.filter_queryset(self.get_queryset())
page = self.paginate_queryset(queryset)
if page is not None:
data = [{'id': p.id, 'name': p.name} for p in page]
return self.get_paginated_response(data)
data = [{'id': p.id, 'name': p.name} for p in queryset]
return Response({'count': len(data), 'results': data})
```
### URL 注册
```python
# api_v1/urls.py
from .views.products import ProductQuickViewSet
main_router.register(r'products/quick', ProductQuickViewSet, basename='product-quick')
```
---
## 文档
完整的 API 文档位于: `api_v1/views/products/API.md`
**文档内容**:
- 接口说明和参数
- 请求/响应示例
- 使用场景（下拉框、自动完成、搜索框）
- Python/JavaScript/curl 示例代码
- 性能优化建议（缓存、防抖）
- 常见问题解答
---
## 使用示例
### Python
```python
import requests
headers = {"Authorization": f"Bearer {token}"}
response = requests.get(
"http://localhost:8000/api/v1/products/quick/?search=布料&limit=10",
headers=headers
)
products = response.json()['results']
```
### JavaScript
```javascript
const response = await fetch('/api/v1/products/quick/?search=布料&limit=10', {
headers: { 'Authorization': `Bearer ${token}` }
});
const { results } = await response.json();
```
### curl
```bash
curl -X GET "http://localhost:8000/api/v1/products/quick/?search=布料&limit=10" \
-H "Authorization: Bearer YOUR_TOKEN"
```
---
## 前端集成
### React Select 示例
```jsx
function ProductSelect() {
const [products, setProducts] = useState([]);
useEffect(() => {
fetch('/api/v1/products/quick/?limit=100', {
headers: { 'Authorization': `Bearer ${token}` }
})
.then(res => res.json())
.then(data => setProducts(data.results));
}, []);
return (
<select>
{products.map(p => (
<option key={p.id} value={p.id}>{p.name}</option>
))}
</select>
);
}
```
### Vue AutoComplete 示例
```vue
<el-autocomplete
v-model="search"
:fetch-suggestions="queryProducts"
@select="handleSelect"
/>
<script setup>
const queryProducts = async (query, cb) => {
const url = `/api/v1/products/quick/?search=${query}&limit=10`;
const res = await fetch(url, {
headers: { 'Authorization': `Bearer ${token}` }
});
const data = await res.json();
cb(data.results.map(p => ({ value: p.name, id: p.id })));
};
</script>
```
---
## 性能考虑
1. **只查询必要字段**: 只返回 id 和 name，减少数据传输
2. **支持分页**: 避免一次性加载大量数据
3. **模糊搜索**: 使用数据库索引优化查询
4. **前端缓存**: 建议缓存常用数据5分钟
5. **防抖搜索**: 建议搜索输入延迟300ms

| `api_v1/views/products/API.md` | 完整文档 |
| `api_v1/urls.py` | URL 路由配置 |
| `basic_info/models.py` | Product 模型定义 |
---
## 扩展建议
### 未来可能的扩展
1. **增加更多字段**: 如需要，可添加 `color`, `spec` 等字段
2. **批量查询**: 支持通过 ID 列表批量查询产品
3. **最近使用**: 记录用户最近选择的产品
4. **推荐功能**: 根据历史记录推荐产品
5. **多语言支持**: 支持产品名称国际化
### 类似接口
可以参考此模式为其他实体创建类似接口：
- `CustomerQuickViewSet` - 客户快速查询
- `WarehouseQuickViewSet` - 仓库快速查询
- `EmployeeQuickViewSet` - 员工快速查询
---
## 总结
✅ **完成状态**: 100%
