# Tag and Search Feature - Implementation Plan
|
||||
|
||||
## Overview
|
||||
Add a comprehensive tag management system with search functionality to allow users to categorize articles with tags and search articles by keywords.
|
||||
|
||||
## Requirements
|
||||
Based on user request:
|
||||
1. **Tag Management**: Add tag functionality to articles
|
||||
2. **Tag Association**: When creating/editing articles, users can associate tags
|
||||
3. **Auto Tag Creation**: If a tag doesn't exist, create it automatically
|
||||
4. **Tag Display**: Show all tags in homepage right sidebar
|
||||
5. **Tag Filtering**: Filter articles by clicking on tags
|
||||
6. **Search Functionality**: Add search box in header to search articles by keywords
|
||||
|
||||
## Current Architecture Patterns
|
||||
|
||||
### Database Models
|
||||
- Models are in `/models/` directory
|
||||
- Use GORM with auto-migration in `models/db.go`
|
||||
- Multi-language support via `*Zh` and `*En` fields pattern
|
||||
- Article model in `models/article.go`
|
||||
|
||||
### Handlers
|
||||
- Article handlers in `handlers/article.go` and `handlers/home.go`
|
||||
- Settings handlers in `handlers/settings.go`
|
||||
- Pattern: `{Feature}Page()` for GET, `{Feature}()` for POST
|
||||
- Uses `DefaultData(c)` helper for common template data
|
||||
|
||||
### Templates
|
||||
- Home page at `templates/pages/home.html`
|
||||
- Article creation/edit at `templates/admin/article_create.html`
|
||||
- Layout header at `templates/layouts/base.html`
|
||||
|
||||
### Routing
|
||||
- Main routes in `main.go`
|
||||
- Public routes for home, article detail, search
|
||||
- Admin routes under `/admin` group with auth middleware
|
||||
|
||||
### i18n
|
||||
- Translation keys in `i18n/i18n.go`
|
||||
- Both EN and ZH translations required
|
||||
|
||||
## Proposed Implementation
|
||||
|
||||
### 1. Database Models
|
||||
|
||||
#### `models/tag.go`
|
||||
```go
|
||||
type Tag struct {
|
||||
ID uint `gorm:"primarykey"`
|
||||
NameZh string `gorm:"size:50;uniqueIndex:idx_tag_name_zh"`
|
||||
NameEn string `gorm:"size:50;uniqueIndex:idx_tag_name_en"`
|
||||
Slug string `gorm:"size:100;uniqueIndex"`
|
||||
Count int `gorm:"default:0"` // Article count cache
|
||||
CreatedAt time.Time
|
||||
UpdatedAt time.Time
|
||||
}
|
||||
|
||||
// Helper method to get tag name by language
|
||||
func (t *Tag) Name(lang string) string {
|
||||
if lang == "zh" {
|
||||
return t.NameZh
|
||||
}
|
||||
return t.NameEn
|
||||
}
|
||||
```
|
||||
|
||||
#### `models/article_tag.go` (Many-to-Many Join Table)
|
||||
```go
|
||||
type ArticleTag struct {
|
||||
ArticleID uint `gorm:"primaryKey;index"`
|
||||
TagID uint `gorm:"primaryKey;index"`
|
||||
CreatedAt time.Time
|
||||
}
|
||||
```
|
||||
|
||||
#### Update `models/article.go`
|
||||
```go
|
||||
type Article struct {
|
||||
// ... existing fields ...
|
||||
Tags []Tag `gorm:"many2many:article_tags;"`
|
||||
}
|
||||
```
|
||||
|
||||
### 2. Database Migration
|
||||
Update `models/db.go` `AutoMigrate()`:
|
||||
- Add `&Tag{}` and `&ArticleTag{}` to the migration list
|
||||
|
||||
### 3. Tag Management Functions
|
||||
|
||||
#### Add to `models/tag.go`:
|
||||
```go
|
||||
// FindOrCreateTag finds a tag by name or creates it if not exists
|
||||
func FindOrCreateTag(db *gorm.DB, nameZh, nameEn string) (*Tag, error)
|
||||
|
||||
// GetAllTags returns all tags ordered by count descending
|
||||
func GetAllTags(db *gorm.DB) ([]Tag, error)
|
||||
|
||||
// GetTagBySlug returns a tag by its slug
|
||||
func GetTagBySlug(db *gorm.DB, slug string) (*Tag, error)
|
||||
|
||||
// UpdateTagCount recalculates article count for a tag
|
||||
func UpdateTagCount(db *gorm.DB, tagID uint) error
|
||||
```
|
||||
|
||||
### 4. Article Handler Updates
|
||||
|
||||
#### Update `handlers/article.go`:
|
||||
|
||||
**Modify `articleForm` struct:**
|
||||
```go
|
||||
type articleForm struct {
|
||||
// ... existing fields ...
|
||||
Tags string // Comma-separated tag names
|
||||
}
|
||||
```
|
||||
|
||||
**Modify `parseArticleForm`:**
|
||||
```go
|
||||
func parseArticleForm(c *gin.Context) articleForm {
|
||||
return articleForm{
|
||||
// ... existing fields ...
|
||||
Tags: strings.TrimSpace(c.PostForm("tags")),
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Modify `applyFormToData`:**
|
||||
```go
|
||||
func applyFormToData(data gin.H, f articleForm) {
|
||||
// ... existing assignments ...
|
||||
data["FormTags"] = f.Tags
|
||||
}
|
||||
```
|
||||
|
||||
**Add `parseTags` helper:**
|
||||
```go
|
||||
// parseTags splits comma-separated tag string and returns tag names
|
||||
func parseTags(tagStr string) []string {
|
||||
if tagStr == "" {
|
||||
return []string{}
|
||||
}
|
||||
parts := strings.Split(tagStr, ",")
|
||||
var tags []string
|
||||
for _, part := range parts {
|
||||
trimmed := strings.TrimSpace(part)
|
||||
if trimmed != "" {
|
||||
tags = append(tags, trimmed)
|
||||
}
|
||||
}
|
||||
return tags
|
||||
}
|
||||
```
|
||||
|
||||
**Add `syncArticleTags` helper:**
|
||||
```go
|
||||
// syncArticleTags associates tags with an article (find or create tags)
|
||||
func syncArticleTags(db *gorm.DB, article *models.Article, tagNames []string) error
|
||||
```
|
||||
|
||||
**Modify `ArticleCreate` and `ArticleUpdate`:**
|
||||
- Parse tags from form
|
||||
- Call `syncArticleTags` after article is created/updated
|
||||
- Update tag counts
|
||||
|
||||
**Modify `ArticleEditPage`:**
|
||||
- Load article with tags preloaded
|
||||
- Format tags as comma-separated string for form
|
||||
|
||||
### 5. Search and Filter Handlers
|
||||
|
||||
#### Add to `handlers/home.go`:
|
||||
|
||||
```go
|
||||
// SearchArticles handles article search by keyword
|
||||
func SearchArticles(db *gorm.DB) gin.HandlerFunc {
|
||||
return func(c *gin.Context) {
|
||||
keyword := strings.TrimSpace(c.Query("q"))
|
||||
tagSlug := strings.TrimSpace(c.Query("tag"))
|
||||
|
||||
// Build query with filters
|
||||
// Return paginated results
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Modify `HomePage` and `HomeArticlesAPI`:**
|
||||
- Add tag filtering support via query parameter
|
||||
- Add search keyword filtering support
|
||||
|
||||
### 6. Template Updates
|
||||
|
||||
#### Update `templates/admin/article_create.html`:
|
||||
Add tag input field after content section:
|
||||
```html
|
||||
<!-- Tags -->
|
||||
<div>
|
||||
<label class="block text-sm font-medium text-gray-700 mb-1">{{index .Tr "article_tags"}}</label>
|
||||
<input type="text" name="tags" value="{{.FormTags}}"
|
||||
class="w-full px-4 py-2 border border-gray-300 rounded-lg focus:ring-2 focus:ring-blue-500 focus:border-blue-500 outline-none transition-colors"
|
||||
placeholder="{{index .Tr "article_tags_hint"}}">
|
||||
<p class="text-xs text-gray-400 mt-1">{{index .Tr "article_tags_hint"}}</p>
|
||||
</div>
|
||||
```
|
||||
|
||||
#### Update `templates/pages/home.html`:
|
||||
|
||||
**Add search box in header (top section):**
|
||||
```html
|
||||
<section class="max-w-5xl mx-auto px-4 py-6">
|
||||
<div class="flex justify-center">
|
||||
<form action="/search" method="get" class="w-full max-w-2xl">
|
||||
<div class="relative">
|
||||
<input type="text" name="q" placeholder="{{index .Tr "search_placeholder"}}"
|
||||
class="w-full px-4 py-3 pl-12 border border-gray-300 rounded-lg focus:ring-2 focus:ring-blue-500 focus:border-blue-500 outline-none transition-colors">
|
||||
<svg class="absolute left-4 top-1/2 transform -translate-y-1/2 w-5 h-5 text-gray-400" fill="none" stroke="currentColor" viewBox="0 0 24 24">
|
||||
<path stroke-linecap="round" stroke-linejoin="round" stroke-width="2" d="M21 21l-6-6m2-5a7 7 0 11-14 0 7 7 0 0114 0z"/>
|
||||
</svg>
|
||||
</div>
|
||||
</form>
|
||||
</div>
|
||||
</section>
|
||||
```
|
||||
|
||||
**Add sidebar for tags:**
|
||||
```html
|
||||
<section class="max-w-7xl mx-auto px-4 py-8">
|
||||
<div class="flex gap-8">
|
||||
<!-- Main content (articles) -->
|
||||
<div class="flex-1">
|
||||
<!-- existing articles container -->
|
||||
</div>
|
||||
|
||||
<!-- Sidebar (tags) -->
|
||||
<aside class="w-64 flex-shrink-0 hidden lg:block">
|
||||
<div class="sticky top-6">
|
||||
<h3 class="text-lg font-bold text-gray-900 mb-4">{{index .Tr "tags_title"}}</h3>
|
||||
<div class="flex flex-wrap gap-2">
|
||||
{{range .Tags}}
|
||||
<a href="/?tag={{.Slug}}"
|
||||
class="px-3 py-1 text-sm bg-gray-100 hover:bg-blue-100 text-gray-700 hover:text-blue-700 rounded-full transition-colors">
|
||||
{{if eq $.Lang "zh"}}{{.NameZh}}{{else}}{{.NameEn}}{{end}}
|
||||
<span class="text-xs text-gray-500">({{.Count}})</span>
|
||||
</a>
|
||||
{{end}}
|
||||
</div>
|
||||
</div>
|
||||
</aside>
|
||||
</div>
|
||||
</section>
|
||||
```
|
||||
|
||||
#### Create `templates/pages/search.html`:
|
||||
New template for search results page with similar layout to home.
|
||||
|
||||
### 7. Routing Updates
|
||||
|
||||
Update `main.go`:
|
||||
```go
|
||||
// Public routes
|
||||
router.GET("/", handlers.HomePage(db))
|
||||
router.GET("/search", handlers.SearchPage(db))
|
||||
router.GET("/api/articles", handlers.HomeArticlesAPI(db))
|
||||
```
|
||||
|
||||
### 8. i18n Translations
|
||||
|
||||
Add to `i18n/i18n.go` for both EN and ZH:
|
||||
```go
|
||||
// Tags
|
||||
"tags_title": "Tags"
|
||||
"article_tags": "Tags"
|
||||
"article_tags_hint": "Comma-separated tag names, e.g., golang, web, tutorial"
|
||||
"tag_filter": "Filter by tag"
|
||||
"tag_all": "All"
|
||||
|
||||
// Search
|
||||
"search_placeholder": "Search articles..."
|
||||
"search_title": "Search Results"
|
||||
"search_results_for": "Search results for"
|
||||
"search_no_results": "No articles found matching your search."
|
||||
"search_keyword": "Keyword"
|
||||
```
|
||||
|
||||
### 9. Homepage Handler Updates
|
||||
|
||||
Update `handlers/home.go`:
|
||||
|
||||
**Modify `HomePage`:**
|
||||
```go
|
||||
func HomePage(db *gorm.DB) gin.HandlerFunc {
|
||||
return func(c *gin.Context) {
|
||||
tr := getTr(c)
|
||||
data := DefaultData(c)
|
||||
|
||||
// Get tag filter if present
|
||||
tagSlug := c.Query("tag")
|
||||
|
||||
// Build query
|
||||
query := db.Where("status = ?", models.ArticlePublished)
|
||||
|
||||
if tagSlug != "" {
|
||||
// Join with article_tags to filter by tag
|
||||
query = query.Joins("JOIN article_tags ON article_tags.article_id = articles.id").
|
||||
Joins("JOIN tags ON tags.id = article_tags.tag_id").
|
||||
Where("tags.slug = ?", tagSlug)
|
||||
}
|
||||
|
||||
var articles []models.Article
|
||||
query.Preload("Tags").
|
||||
Order(publishedArticleOrder).
|
||||
Limit(10).
|
||||
Find(&articles)
|
||||
|
||||
// Load all tags for sidebar
|
||||
var tags []models.Tag
|
||||
db.Order("count DESC, name_zh ASC").Find(&tags)
|
||||
|
||||
data["Articles"] = articles
|
||||
data["Tags"] = tags
|
||||
if tagSlug != "" {
|
||||
data["FilterTag"] = tagSlug
|
||||
}
|
||||
|
||||
// ... existing comment counts logic ...
|
||||
|
||||
c.HTML(http.StatusOK, "home", data)
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Add `SearchPage` handler:**
|
||||
```go
|
||||
func SearchPage(db *gorm.DB) gin.HandlerFunc {
|
||||
return func(c *gin.Context) {
|
||||
keyword := strings.TrimSpace(c.Query("q"))
|
||||
// Search in title, summary, and content
|
||||
// Render search results template
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Implementation Order
|
||||
|
||||
1. **Create database models** (`models/tag.go`, `models/article_tag.go`)
|
||||
2. **Update article model** to add Tags relationship
|
||||
3. **Update database migration** (`models/db.go`)
|
||||
4. **Add tag helper functions** in `models/tag.go`
|
||||
5. **Add i18n translations** (`i18n/i18n.go`)
|
||||
6. **Update article handlers** (`handlers/article.go`) - form parsing, tag syncing
|
||||
7. **Update article templates** (`templates/admin/article_create.html`) - add tag input
|
||||
8. **Update home handler** (`handlers/home.go`) - add tag filtering, search
|
||||
9. **Update home template** (`templates/pages/home.html`) - add search box, tag sidebar
|
||||
10. **Create search page template** (`templates/pages/search.html`)
|
||||
11. **Add routes** (`main.go`)
|
||||
12. **Test the feature**
|
||||
|
||||
## Design Decisions
|
||||
|
||||
### Tag Storage
|
||||
- Store both Chinese and English names for multi-language support
|
||||
- Use slug for URL-friendly tag filtering
|
||||
- Cache article count in tag table for performance
|
||||
|
||||
### Tag Input Format
|
||||
- Simple comma-separated text input for ease of use
|
||||
- Auto-trim whitespace
|
||||
- No autocomplete in MVP (can be added later)
|
||||
|
||||
### Tag Creation
|
||||
- Auto-create tags on article save
|
||||
- No separate admin UI for tag management in MVP
|
||||
- Tags are created based on article associations
|
||||
|
||||
### Search Implementation
|
||||
- Full-text search in title, summary, and content fields
|
||||
- Case-insensitive matching
|
||||
- Simple LIKE query (can be upgraded to full-text search later)
|
||||
- Support pagination
|
||||
|
||||
### Tag Filtering
|
||||
- Filter by single tag via query parameter `?tag=slug`
|
||||
- Show filtered tag in UI for user clarity
|
||||
- Compatible with infinite scroll
|
||||
|
||||
### UI Layout
|
||||
- Search box prominent in header area
|
||||
- Tag sidebar on right (desktop only, hidden on mobile)
|
||||
- Tag cloud style with article count badges
|
||||
- Responsive design maintained
|
||||
|
||||
## Testing Checklist

||||
|
||||
- [ ] Create article with tags
|
||||

# 标签筛选功能修复总结
|
||||
|
||||
## 问题描述
|
||||
用户报告：无法通过tag筛选文章
|
||||
|
||||
## 根本原因
|
||||
SQL 查询中存在**列名歧义**错误：
|
||||
```
|
||||
SQL logic error: ambiguous column name: created_at (1)
|
||||
```
|
||||
|
||||
在使用 JOIN 查询时，`articles` 和 `article_tags` 表都有 `created_at` 字段，导致 ORDER BY 子句中的列名不明确。
|
||||
|
||||
## 修复方案
|
||||
|
||||
### 修改文件：`handlers/home.go`
|
||||
|
||||
**修改前：**
|
||||
```go
|
||||
const publishedArticleOrder = "is_top DESC, published_at DESC, created_at DESC"
|
||||
```
|
||||
|
||||
**修改后：**
|
||||
```go
|
||||
const publishedArticleOrder = "articles.is_top DESC, articles.published_at DESC, articles.created_at DESC"
|
||||
```
|
||||
|
||||
**说明：**
|
||||
在 ORDER BY 子句中为所有列名添加表前缀 `articles.`，明确指定是 articles 表的字段。
|
||||
|
||||
## 验证结果
|
||||
|
||||
### ✅ 修复后测试通过
|
||||
|
||||
1. **SQL 错误消失**
|
||||
- 不再出现 "ambiguous column name" 错误
|
||||
- 查询正常执行
|
||||
|
||||
2. **标签筛选正常工作**
|
||||
```
|
||||
访问: http://localhost:8080/?tag=fr
|
||||
```
|
||||
- 显示筛选提示：`Filter by tag: fr`
|
||||
- 显示"All"链接返回所有文章
|
||||
- 只显示包含该标签的文章
|
||||
|
||||
3. **标签侧边栏正常显示**
|
||||
- 显示所有标签及其文章数量
|
||||
- 例如：`fr (1)`, `fs (2)` 等
|
||||
|
||||
4. **API 也支持标签筛选**
|
||||
```
|
||||
GET /api/articles?tag=fr
|
||||
```
|
||||
|
||||
## 使用说明
|
||||
|
||||
### 创建带标签的文章
|
||||
1. 访问 http://localhost:8080/admin/articles/new
|
||||
2. 登录（用户名：admin，密码：admin）
|
||||
3. 填写文章信息
|
||||
4. 在"标签"字段输入：`golang, web, 教程`（逗号分隔）
|
||||
5. 点击"发布"或"保存草稿"
|
||||
|
||||
### 通过标签筛选文章
|
||||
1. 访问主页 http://localhost:8080/
|
||||
2. 在右侧标签云中点击任意标签
|
||||
3. 页面刷新，只显示包含该标签的文章
|
||||
4. 顶部显示筛选提示，点击"All"返回所有文章
|
||||
|
||||
### 通过URL直接筛选
|
||||
```
|
||||
http://localhost:8080/?tag=golang
|
||||
http://localhost:8080/?tag=web
|
||||
```
|
||||
|
||||
## 技术细节
|
||||
|
||||
### 修复影响的查询
|
||||
此修复影响以下两个处理器中的标签筛选查询：
|
||||
|
||||
1. **HomePage** (`handlers/home.go`)
|
||||
- 主页文章列表的标签筛选
|
||||
|
||||
2. **HomeArticlesAPI** (`handlers/home.go`)
|
||||
- 无限滚动 API 的标签筛选
|
||||
|
||||
### 为什么会出现这个问题？
|
||||
|
||||
当使用 JOIN 查询多个表时，如果多个表有同名字段，SQL 引擎无法确定 ORDER BY 或 WHERE 子句中引用的是哪个表的字段。
|
||||
|
||||
**原始查询：**
|
||||
```sql
|
||||
SELECT articles.*
|
||||
FROM articles
|
||||
JOIN article_tags ON article_tags.article_id = articles.id
|
||||
JOIN tags ON tags.id = article_tags.tag_id
|
||||
WHERE status = 1 AND tags.slug = "golang"
|
||||
ORDER BY is_top DESC, published_at DESC, created_at DESC
|
||||
-- ❌ created_at 既在 articles 表中，也在 article_tags 表中
|
||||
```
|
||||
|
||||
**修复后的查询：**
|
||||
```sql
|
||||
SELECT articles.*
|
||||
FROM articles
|
||||
JOIN article_tags ON article_tags.article_id = articles.id
|
||||
JOIN tags ON tags.id = article_tags.tag_id
|
||||
WHERE status = 1 AND tags.slug = "golang"
|
||||
ORDER BY articles.is_top DESC, articles.published_at DESC, articles.created_at DESC
|
||||
-- ✅ 明确指定使用 articles 表的字段
|
||||
```
|
||||
|
||||
## 相关功能测试清单

|
||||
|
||||
## 其他修复建议
|
||||
|
||||
为了避免类似问题，建议在所有使用 JOIN 的查询中：
|
||||
|
||||
1. **始终使用表前缀**
|
||||
- 在 SELECT、WHERE、ORDER BY 中明确指定表名
|
||||
|
||||
2. **使用表别名**
|
||||
```go
|
||||
query.Joins("JOIN article_tags at ON at.article_id = articles.id").
|
||||
Joins("JOIN tags t ON t.id = at.tag_id").
|
||||
Where("t.slug = ?", tagSlug).
|
||||
Order("articles.is_top DESC, articles.created_at DESC")
|
||||
```
|
||||
|
||||
3. **GORM 最佳实践**
|
||||
- 使用 `db.Table("articles a")` 定义别名
|
||||
- 在复杂查询中使用 Raw SQL 或子查询
|
||||
|
||||
## 文件变更
|
||||
|
||||
### 修改的文件
|
||||
- `handlers/home.go` - 修复列名歧义问题
|
||||
|
||||
### 测试状态

# 标签和搜索功能实施总结
|
||||
|
||||
## 概述
|
||||
成功实现了完整的标签管理系统和文章搜索功能，允许用户通过标签分类文章，并通过关键字搜索文章。
|
||||
|
||||
## 已完成的功能
|
||||
|
||||
### 1. 数据库模型
|
||||
|
||||
#### Tag 模型 (`models/tag.go`)
|
||||
- 支持中英文双语标签名称
|
||||
- 使用 slug 作为 URL 友好的标识符
|
||||
- 缓存文章计数以提高性能
|
||||
- 提供查找或创建标签的辅助函数
|
||||
- 自动生成 slug
|
||||
- 支持更新标签计数
|
||||
|
||||
#### ArticleTag 模型 (`models/article_tag.go`)
|
||||

|
||||
|
||||
#### Article 模型更新
|
||||
- 添加了 `Tags` 字段，建立多对多关系
|
||||
- 自动加载关联的标签
|
||||
|
||||
### 2. 数据库迁移
|
||||
- 在 `models/db.go` 中添加了 `Tag` 和 `ArticleTag` 的自动迁移
|
||||
- 数据库会在启动时自动创建相关表
|
||||
|
||||
### 3. 文章处理器增强 (`handlers/article.go`)
|
||||
|
||||
#### 新增功能
|
||||
- **标签解析**: `parseTags()` - 从逗号分隔的字符串解析标签
|
||||
- **标签同步**: `syncArticleTags()` - 同步文章与标签的关联关系
|
||||
- **标签格式化**: `formatArticleTags()` - 将标签数组转换为表单显示格式
|
||||
|
||||
#### 表单更新
|
||||
- `articleForm` 结构体添加了 `Tags` 字段
|
||||
- `parseArticleForm()` 解析标签输入
|
||||
- `applyFormToData()` 将标签数据传递给模板
|
||||
|
||||
#### 文章创建/编辑
|
||||
- **ArticleCreate**: 创建文章时自动关联标签，不存在的标签会自动创建
|
||||
- **ArticleUpdate**: 更新文章时同步标签关联
|
||||
- **ArticleEditPage**: 编辑页面预加载现有标签并显示在表单中
|
||||
|
||||
### 4. 主页和搜索处理器 (`handlers/home.go`)
|
||||
|
||||
#### HomePage 增强
|
||||
- 支持通过 `?tag=slug` 参数筛选文章
|
||||
- 加载所有标签用于侧边栏显示
|
||||
- 预加载文章的标签信息
|
||||
- 显示当前筛选的标签
|
||||
|
||||
#### HomeArticlesAPI 增强
|
||||
- API 支持标签筛选
|
||||
- 返回的文章包含标签信息
|
||||
- 保持无限滚动功能
|
||||
|
||||
#### SearchPage (新增)
|
||||
- 通过 `?q=keyword` 参数搜索文章
|
||||
- 在标题、摘要和正文中搜索关键字
|
||||
- 支持大小写不敏感搜索
|
||||
- 限制最多返回 50 条结果
|
||||
- 显示搜索关键字和结果数量
|
||||
|
||||
### 5. 模板更新
|
||||
|
||||
#### 文章创建/编辑表单 (`templates/admin/article_create.html`)
|
||||
- 添加标签输入框
|
||||
- 显示标签输入提示（逗号分隔）
|
||||
- 位于封面图片字段之后
|
||||
|
||||

||||
- **响应式布局**: 大屏幕显示侧边栏，小屏幕自动隐藏
|
||||
|
||||
#### 搜索结果页 (`templates/pages/search.html`)
|
||||
- 独立的搜索结果页面
|
||||
- 保留搜索框并显示搜索关键字
|
||||
- 显示搜索结果数量
|
||||
- 显示匹配的文章列表
|
||||
- 包含标签侧边栏
|
||||
- 支持图片布局的智能适配（横向/纵向）
|
||||
|
||||
### 6. 国际化支持 (`i18n/i18n.go`)
|
||||
|
||||
#### 新增翻译键（中英文）
|
||||
- `tags_title`: "标签" / "Tags"
|
||||
- `article_tags`: "标签" / "Tags"
|
||||
- `article_tags_hint`: 标签输入提示
|
||||
- `tag_filter`: "按标签筛选" / "Filter by tag"
|
||||
- `tag_all`: "全部" / "All"
|
||||
- `search_placeholder`: "搜索文章..." / "Search articles..."
|
||||
- `search_title`: "搜索结果" / "Search Results"
|
||||
- `search_results_for`: "搜索结果" / "Search results for"
|
||||
- `search_no_results`: "未找到匹配的文章。" / "No articles found matching your search."
|
||||
- `search_keyword`: "关键词" / "Keyword"
|
||||
|
||||
### 7. 路由配置 (`main.go`)
|
||||
- 添加 `/search` 路由，映射到 `SearchPage` 处理器
|
||||
- 保持现有路由不变
|
||||
|
||||
## 技术特性
|
||||
|
||||
### 性能优化
|
||||
1. **标签计数缓存**: 在 Tag 表中缓存文章数量，避免频繁联表查询
|
||||
2. **预加载关联**: 使用 GORM 的 Preload 功能一次性加载文章的标签
|
||||
3. **索引优化**: ArticleTag 表在 article_id 和 tag_id 上建立索引
|
||||
|
||||
### 用户体验
|
||||
1. **自动标签创建**: 用户输入不存在的标签时自动创建
|
||||
2. **智能搜索**: 支持在标题、摘要和正文中搜索
|
||||
3. **可视化标签**: 显示每个标签关联的文章数量
|
||||
4. **筛选提示**: 明确显示当前筛选状态
|
||||
5. **响应式设计**: 移动端友好的布局
|
||||
|
||||
### 数据一致性
|
||||
1. **标签同步**: 更新文章时先清除旧标签，再添加新标签
|
||||
2. **计数更新**: 修改标签关联后自动更新计数
|
||||
3. **错误处理**: 标签操作失败不影响文章的创建/更新
|
||||
|
||||
## 使用方法
|
||||
|
||||
### 创建带标签的文章
|
||||
1. 进入文章创建/编辑页面
|
||||
2. 在"标签"字段输入逗号分隔的标签名称，如：`golang, web, 教程`
|
||||
3. 保存文章后，标签会自动创建并关联
|
||||
|
||||
### 按标签筛选文章
|
||||
1. 在主页右侧标签列表中点击任意标签
|
||||
2. 页面刷新，只显示包含该标签的文章
|
||||
3. 点击"全部"返回查看所有文章
|
||||
|
||||
### 搜索文章
|
||||
1. 在页面顶部搜索框输入关键字
|
||||
2. 按回车或点击搜索
|
||||
3. 查看匹配的文章列表
|
||||
|
||||
