+      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 = {

+        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

+| 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/" \

+  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;
+}
+```

+
+## 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')
+```

+
+## 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
