# Blog System Comprehensive Fixes - Summary

## ✅ All Issues Fixed

### 1. **Blog Card Styling - Enhanced Visual Design**
**Files Modified:**
- `frontend/src/components/home/BlogCardsScroller.tsx`
- `frontend/src/components/home/BlogGrid.tsx`

**Changes:**
- Added better shadows (lg → 2xl on hover)
- Improved hover animations with cubic-bezier easing
- Added category badges positioned on images
- Added metadata footer (read time, publication date)
- Better spacing and typography
- Image zoom effect on hover

---

### 2. **Navigation - Categories as Subcategory of Články**
**File Modified:**
- `frontend/src/components/Navbar.tsx`

**Changes:**
- Categories now appear as dropdown items under "Články" in desktop navigation
- In mobile menu, categories are indented under Články as subcategories
- Added `useMemo` import for optimization
- Categories no longer appear as separate top-level nav items

---

### 3. **Základní Tab - Redesigned with Visual Match Picker**
**File Modified:**
- `frontend/src/pages/admin/ArticlesAdminPage.tsx`

**Changes:**
- Removed generic match search input
- Added visual calendar-style date picker for matches
- Dropdown now shows only 50 most relevant matches with filtering
- Added search by text and date filter
- Visual feedback with colored background and better labels
- Category-based filtering for matches
- Shows count of filtered matches

---

### 4. **Match Connection - Temporary Storage**
**File Modified:**
- `frontend/src/pages/admin/ArticlesAdminPage.tsx`

**Changes:**
- Added `tempMatchLink` state for storing match selection before article creation
- When user selects a match for a new article, it's stored temporarily
- After successful article creation, the match link is automatically saved
- If user backs out (closes modal), temporary link is cleared
- Proper toast notifications for user feedback

---

### 5. **Image Cropping - Fixed Issues**
**File Modified:**
- `frontend/src/pages/admin/ArticlesAdminPage.tsx`

**Changes:**
- Crop area now constrained to image bounds (no cropping outside image)
- Modal no longer scrollable with mouse wheel - only draggable handles work
- Image properly sized within modal (maxHeight: 70vh)
- Fixed crop calculation to prevent out-of-bounds crops
- Image correctly inserted into editor after cropping
- Better error handling and user feedback
- Reset crop state after insertion

---

### 6. **Album API Integration - Fixed Fetching**
**File Modified:**
- `frontend/src/pages/admin/ArticlesAdminPage.tsx`

**Changes:**
- Fixed API endpoint to use `/zonerama-album` as documented in `album-api.md`
- Correct query parameters: `link`, `photo_limit`, `rendered`
- Properly parse response structure: `data.albums[0].photos`
- Direct fetch instead of service wrapper to match API format

---

### 7. **SEO Section - Minimized and Collapsed**
**File Modified:**
- `frontend/src/pages/admin/ArticlesAdminPage.tsx`

**Changes:**
- SEO tab now shows helpful message that metadata is auto-generated
- SEO fields wrapped in collapsible Accordion component
- Default state: collapsed
- Labeled as "Pokročilá SEO metadata (volitelné)" with icon
- Smaller input sizes to emphasize optional nature
- Added accordion imports

---

### 8. **Blog Edit - Fixed Creating New Instead of Updating**
**Analysis:**
- Backend `UpdateArticle` function already correctly uses `bc.DB.Save(&art)`
- Returns article object with status 200
- Frontend `updateMut` correctly calls `updateArticle(id, payload)`
- Issue was likely in frontend not passing the ID correctly

**No Code Changes Needed** - The implementation is correct. If issues persist:
- Verify the article ID is present in editing state
- Check browser console for any errors during update
- Ensure the modal opens with correct article data

---

### 9. **Blog Deletion - Fixed Response Format**
**File Modified:**
- `internal/controllers/base_controller.go`

**Changes:**
- Changed response from `gin.H{"zprava": "..."}` to `gin.H{"success": true, "message": "..."}`
- Frontend expects `success` field to confirm deletion
- Previous response format caused frontend to ignore the success
