# Blog Match Link Fix - October 2025
|
||||
|
||||
## Problem
|
||||
React Error #310 (Maximum update depth exceeded) - infinite render loop caused by backend returning `map[string]interface{}` instead of Article structs. Each map created new object references, triggering infinite re-renders in React useEffect hooks.
|
||||
|
||||
## Root Cause
|
||||
Previous attempt to add match link data to article JSON responses used helper functions that returned maps instead of structs. This broke React's referential equality checks.
|
||||
|
||||
## Solution
|
||||
|
||||
### 1. Added MatchLink Field to Article Model
|
||||
**File**: `internal/models/models.go`
|
||||
|
||||
```go
|
||||
type Article struct {
|
||||
// ... existing fields ...
|
||||
|
||||
// Match link (loaded separately, not stored in this table)
|
||||
MatchLink *ArticleMatchLink `gorm:"-" json:"match_link,omitempty"`
|
||||
}
|
||||
```
|
||||
|
||||
The `gorm:"-"` tag prevents GORM from treating it as a database column, and `omitempty` keeps it out of JSON if nil.
|
||||
|
||||
### 2. Updated Backend Controllers
|
||||
**File**: `internal/controllers/base_controller.go`
|
||||
|
||||
#### GetArticle (single article by ID)
|
||||
- Loads match link after fetching article
|
||||
- Sets `art.MatchLink` if found
|
||||
|
||||
#### GetArticles (paginated list)
|
||||
- Batch loads all match links for returned articles in single query
|
||||
- Maps match links to articles by ID for O(1) lookup
|
||||
- Efficient: one extra query regardless of result set size
|
||||
|
||||
#### GetArticleBySlug (single article by slug)
|
||||
- Same as GetArticle - loads match link if exists
|
||||
|
||||
### 3. Simplified Frontend
|
||||
**File**: `frontend/src/pages/admin/ArticlesAdminPage.tsx`
|
||||
|
||||
- **Removed**: Redundant useEffect that fetched match link separately
|
||||
- **Kept**: openEdit() function that extracts match_link from article data
|
||||
- **Result**: Fewer API calls, no infinite loops
|
||||
|
||||
## Benefits
|
||||
|
||||
1. **No Infinite Loops**: Article structs maintain referential equality
|
||||
2. **Complete Data**: Article JSON now includes both competition AND match data
|
||||
3. **Better Performance**: Batch loading for lists (N+1 → 2 queries)
|
||||
4. **Backward Compatible**: Match link is optional (`omitempty`)
|
||||
5. **Cleaner Code**: No complex map transformations
|
||||
|
||||
## Album Link Reuse
|
||||
|
||||
The album link reuse feature was **already implemented** (lines 400-415 in ArticlesAdminPage.tsx). When photos are selected in the Obsah tab, both the album link AND photos are automatically populated in the Media tab.
|
||||
|
||||
**Enhancement made**: Improved UI feedback with green background and clear status messages when album is loaded.
|
||||
|
||||
## Article JSON Structure
|
||||
|
||||
Articles now include:
|
||||
|
||||
```json
|
||||
{
|
||||
"id": 123,
|
||||
"title": "Match Report",
|
||||
"category_name": "A třída",
|
||||
"gallery_album_url": "https://eu.zonerama.com/...",
|
||||
"youtube_video_id": "abc123",
|
||||
"match_link": {
|
||||
"external_match_id": "match-abc-123",
|
||||
"title": "Home Team vs Away Team"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Testing
|
||||
|
||||
Test that:
|
||||
1. ✅ No React infinite loop errors
|
||||
2. ✅ Match link appears in article JSON responses
|
||||
3. ✅ Match link displays correctly in admin UI
|
||||
4. ✅ Album link persists between Obsah and Media tabs
|
||||
5. ✅ All article endpoints work (GetArticle, GetArticles, GetArticleBySlug)
|
||||
|
||||
## Files Modified
|
||||
|
||||
- `internal/models/models.go` - Added MatchLink field
|
||||
- `internal/controllers/base_controller.go` - Load match links in 3 endpoints
|
||||
- `frontend/src/pages/admin/ArticlesAdminPage.tsx` - Removed redundant fetch, improved UI

# Rich Text Editor Image Editing - Critical Fixes Applied
|
||||
|
||||
**Date:** October 19, 2025
|
||||
**Component:** CustomRichEditor.tsx
|
||||
**Status:** ✅ Fixed and Ready for Testing
|
||||
|
||||
## Issues Fixed
|
||||
|
||||
### 1. ✅ Popup Disappearing Immediately
|
||||
**Problem:** Image editing toolbar appeared for a split second and disappeared.
|
||||
|
||||
**Root Cause:** Event propagation was not properly stopped, causing click events to bubble up and trigger the deselect logic.
|
||||
|
||||
**Fix Applied:**
|
||||
- Added `e.stopImmediatePropagation()` to image click handlers
|
||||
- Enhanced toolbar event handlers with comprehensive event stopping
|
||||
- Added better event detection for toolbar and resize handle clicks
|
||||
- Prevented click events from bubbling through the DOM hierarchy
|
||||
|
||||
**Code Changes:**
|
||||
```typescript
|
||||
// Image click handler now properly stops all propagation
|
||||
e.preventDefault();
|
||||
e.stopPropagation();
|
||||
e.stopImmediatePropagation();
|
||||
|
||||
// Toolbar with complete event isolation
|
||||
onClick={(e) => { e.preventDefault(); e.stopPropagation(); e.stopImmediatePropagation(); }}
|
||||
onMouseDown={(e) => { e.preventDefault(); e.stopPropagation(); e.stopImmediatePropagation(); }}
|
||||
onMouseUp={(e) => { e.preventDefault(); e.stopPropagation(); e.stopImmediatePropagation(); }}
|
||||
```
|
||||
|
||||
### 2. ✅ Image Copying When Dragging
|
||||
**Problem:** Moving an image would duplicate it instead of repositioning it.
|
||||
|
||||
**Root Cause:** The drag handler was changing alignment on every mouse move without tracking the current state, causing multiple style changes that appeared as copying.
|
||||
|
||||
**Fix Applied:**
|
||||
- Track current alignment state during drag operations
|
||||
- Only update alignment when it actually changes
|
||||
- Reset start position after each alignment change
|
||||
- Require significant movement (50px) before triggering alignment change
|
||||
- Store initial alignment to prevent unwanted changes
|
||||
|
||||
**Code Changes:**
|
||||
```typescript
|
||||
// Store initial alignment to prevent copying behavior
|
||||
const initialMarginLeft = selectedImage.style.marginLeft || '';
|
||||
const initialMarginRight = selectedImage.style.marginRight || '';
|
||||
let currentAlignment: 'left' | 'center' | 'right' = 'center';
|
||||
|
||||
// Determine initial alignment
|
||||
if (initialMarginLeft === '0' || initialMarginLeft === '0px') {
|
||||
currentAlignment = 'left';
|
||||
} else if (initialMarginRight === '0' || initialMarginRight === '0px') {
|
||||
currentAlignment = 'right';
|
||||
}
|
||||
|
||||
// Only update if alignment actually changed
|
||||
if (newAlignment !== currentAlignment) {
|
||||
currentAlignment = newAlignment;
|
||||
startX = e.clientX; // Reset start position
|
||||
// Apply new alignment
|
||||
}
|
||||
```
|
||||
|
||||
### 3. ✅ Enhanced Resize Handles
|
||||
**Problem:** Only corner resize handle, no edge handles.
|
||||
|
||||
**New Features:**
|
||||
- **4 Edge Handles:** Right, Bottom, Left, Top (thin blue bars, 60% height/width)
|
||||
- **4 Corner Handles:** All corners (circular blue dots)
|
||||
- Proper cursor indicators for each handle type
|
||||
- Smooth hover effects
|
||||
- Maintains aspect ratio for vertical edge resizing
|
||||
|
||||
**Handle Types:**
|
||||
- **Corners:** `nwse-resize` / `nesw-resize` cursors, circular blue dots with white borders
|
||||
- **Horizontal Edges:** `ew-resize` cursor, vertical blue bars
|
||||
- **Vertical Edges:** `ns-resize` cursor, horizontal blue bars
|
||||
|
||||
### 4. ✅ Delete Button
|
||||
**Location:** Image editing toolbar
|
||||
**Icon:** Trash icon (red)
|
||||
**Functionality:** Immediately removes selected image
|
||||
**Keyboard Shortcut:** Delete or Backspace keys

# MyUIbrix - Hlavní Opravy a Vylepšení (Říjen 2025)
|
||||
|
||||
## 📋 Přehled
|
||||
|
||||
Kompletní přepracování MyUIbrix editoru s opravami kritických chyb, vylepšeným UX a optimalizací výkonu.
|
||||
|
||||
---
|
||||
|
||||
## 🔧 Opravené Problémy
|
||||
|
||||
### 1. **Responzivní Viewport - OPRAVENO** ✅
|
||||
|
||||
**Problém:**
|
||||
- Viewport switcher používal relativní šířky (50%, 70%)
|
||||
- Nezobrazoval reálné rozlišení mobilů a tabletů
|
||||
- Lagoval a nefungoval správně
|
||||
- Neposkytoval přesný náhled různých zařízení
|
||||
|
||||
**Řešení:**
|
||||
- ✅ Mobilní viewport: **375px** (iPhone standardní šířka)
|
||||
- ✅ Tablet viewport: **768px** (iPad portrait)
|
||||
- ✅ Desktop viewport: **100%** (plná šířka)
|
||||
- ✅ Přidány toast notifikace při změně viewportu
|
||||
- ✅ Vizuální indikátory (border + shadow) pro non-desktop režimy
|
||||
- ✅ Tooltip s přesným rozlišením
|
||||
|
||||
**Výsledek:**
|
||||
```typescript
|
||||
// PŘED
|
||||
case 'mobile': return '50%'; // ❌ Relativní
|
||||
case 'tablet': return '70%'; // ❌ Relativní
|
||||
|
||||
// PO
|
||||
case 'mobile': return '375px'; // ✅ Reálná šířka iPhonu
|
||||
case 'tablet': return '768px'; // ✅ Reálná šířka iPadu
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 2. **Auto-otevření Editoru - NOVÁ FUNKCE** ✅
|
||||
|
||||
**Problém:**
|
||||
- Nutnost klikat na ikonu ⚙️ pro otevření stylu
|
||||
- Dva kroky místo jednoho
|
||||
- Zbytečné komplikace v UX
|
||||
|
||||
**Řešení:**
|
||||
- ✅ **Přímý klik na element** otevře style panel
|
||||
- ✅ Tlačítko ⚙️ stále funguje (pro uživatele, kteří jsou zvyklí)
|
||||
- ✅ Automatické otevření Visual Style Panel
|
||||
- ✅ Okamžité zobrazení dostupných variant
|
||||
|
||||
**Kód:**
|
||||
```typescript
|
||||
// Přidáno do overlay event listeners
|
||||
overlay.addEventListener('click', (e) => {
|
||||
if ((e.target as HTMLElement).closest('.elementor-actions')) {
|
||||
return; // Ignorovat akční tlačítka
|
||||
}
|
||||
e.stopPropagation();
|
||||
setSelectedElement(elementName);
|
||||
setShowStylePanel(true); // 🎯 Auto-otevření
|
||||
});
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 3. **Pády při Změně Stylů - OPRAVENO** ✅
|
||||
|
||||
**Problém:**
|
||||
- Některé změny stylů způsobovaly crash stránky
|
||||
- Elementy mizely po změně varianty
|
||||
- DOM konflikty při rychlých změnách
|
||||
- Chybějící error handling
|
||||
|
||||
**Řešení:**
|
||||
- ✅ **Validace variant** před aplikací
|
||||
- ✅ Try-catch bloky s user-friendly chybovými hláškami
|
||||
- ✅ `requestAnimationFrame()` pro prevenci DOM konfliktů
|
||||
- ✅ Čekání na dokončení reorderu před změnou stylu
|
||||
- ✅ Debouncing (100ms) pro style changes
|
||||
|
||||
**Kód:**
|
||||
```typescript
|
||||
const handleVariantChange = useCallback((elementName: string, variant: string) => {
|
||||
// 1. Validace
|
||||
const variants = ELEMENT_VARIANTS[elementName];
|
||||
if (!variants || !variants.find(v => v.value === variant)) {
|
||||
console.warn(`Invalid variant "${variant}"`);
|
||||
return;
|
||||
}
|
||||
|
||||
try {
|
||||
// 2. Bezpečná aplikace
|
||||
setLocalChanges(newChanges);
|
||||
setConfigs(updated);
|
||||
|
||||
// 3. RAF pro prevenci konfliktů
|
||||
if (isEditing) {
|
||||
requestAnimationFrame(() => {
|
||||
window.dispatchEvent(new CustomEvent('myuibrix-change', {...}));
|
||||
});
|
||||
}
|
||||
} catch (error) {
|
||||
// 4. Error handling
|
||||
toast({
|
||||
title: 'Chyba při aplikaci stylu',
|
||||
status: 'error',
|
||||
});
|
||||
}
|
||||
}, [localChanges, visibleElements, isEditing, toast]);
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 4. **Optimalizace Výkonu** ✅
|
||||
|
||||
**Problémy:**
|
||||
- Lagování při rychlých změnách
|
||||
- Příliš mnoho DOM manipulací
|
||||
- Event listeners neuklízeny
|
||||
- Memory leaky
|
||||
- Zbytečné re-renders
|
||||
|
||||
**Řešení:**
|
||||
|
||||
#### A) Debouncing Style Changes
|
||||
```typescript
|
||||
const debounceTimerRef = useRef<NodeJS.Timeout | null>(null);
|
||||
|
||||
const handleStyleChange = useCallback((elementName, styles) => {
|
||||
setElementStyles(prev => ({ ...prev, [elementName]: styles }));
|
||||
|
||||
// Debounce dispatch
|
||||
if (debounceTimerRef.current) {
|
||||
clearTimeout(debounceTimerRef.current);
|
||||
}
|
||||
|
||||
debounceTimerRef.current = setTimeout(() => {
|
||||
window.dispatchEvent(new CustomEvent('myuibrix-style-change', {...}));
|
||||
}, 100); // 🚀 100ms debounce
|
||||
}, [isEditing]);
|
||||
```
|
||||
|
||||
#### B) Memoization
|
||||
```typescript
|
||||
// PŘED - Každý render
|
||||
const currentVariants = selectedElement ? ELEMENT_VARIANTS[selectedElement] : [];
|
||||
|
||||
// PO - Pouze když se změní selectedElement
|
||||
const currentVariants = useMemo(() =>
|
||||
selectedElement ? ELEMENT_VARIANTS[selectedElement] || [] : [],
|
||||
[selectedElement]
|
||||
);
|
||||
```
|
||||
|
||||
#### C) Cleanup Event Listeners
|
||||
```typescript
|
||||
return () => {
|
||||
// Odstranění všech event listeners
|
||||
document.querySelectorAll('.elementor-overlay').forEach(el => {
|
||||
const clone = el.cloneNode(true);
|
||||
el.replaceWith(clone); // 🧹 Odstraní všechny listeners
|
||||
clone.remove();
|
||||
});
|
||||
|
||||
// Vyčištění timers
|
||||
if (debounceTimerRef.current) {
|
||||
clearTimeout(debounceTimerRef.current);
|
||||
}
|
||||
};
|
||||
```
|
||||

## 🐛 Debug Tips
|
||||
|
||||
### Pokud element mizí po změně:
|
||||
```javascript
|
||||
// Console check:
|
||||
console.log(ELEMENT_VARIANTS['elementName']);
|
||||
// Ujistěte se, že varianta existuje
|
||||
```
|
||||
|
||||
### Pokud viewport nefunguje:
|
||||
```javascript
|
||||
// Check wrapper:
|
||||
const wrapper = document.querySelector('.myuibrix-viewport-wrapper');
|
||||
console.log(wrapper?.style.width); // Mělo by být '375px', '768px', nebo '100%'
|
||||
```
|
||||
|
||||
### Pokud je lagování:
|
||||
```javascript
|
||||
// Check debounce:
|
||||
// V DevTools > Performance > zaznamenejte změnu stylu
|
||||
// Mělo by být pouze 1 dispatch každých 100ms
|
||||
```

## Umami v2 Compatibility Update (Latest Fix)
|
||||
|
||||
### Problem with Umami v2
|
||||
In Umami v2, when users are part of teams, creating a website may require specifying a `teamId`. Without this parameter, the website creation request could fail.
|
||||
|
||||
### Solution Implemented
|
||||
Updated `CreateWebsite()` method in `umami_service.go` to:
|
||||
|
||||
1. **Fetch current user information** via `POST /api/auth/verify`
|
||||
2. **Retrieve user's teams** via `GET /api/users/:userId/teams`
|
||||
3. **Automatically use the first available team** when creating a website
|
||||
4. **Gracefully degrade** if teams cannot be fetched (continues without teamId)
|
||||
|
||||
### New Methods Added
|
||||
```go
|
||||
// GetCurrentUser - Retrieves authenticated user info from Umami
|
||||
func (u *UmamiService) GetCurrentUser() (map[string]interface{}, error)
|
||||
|
||||
// GetUserTeams - Retrieves user's teams from Umami
|
||||
func (u *UmamiService) GetUserTeams(userID string) ([]UmamiTeam, error)
|
||||
```
|
||||
|
||||
### Updated CreateWebsite Flow
|
||||
```
|
||||
1. Authenticate with Umami
|
||||
2. Get current user info (to obtain user ID)
|
||||
3. Fetch user's teams (if user has teams)
|
||||
4. Prepare website creation request with:
|
||||
- name: Website name
|
||||
- domain: Website domain
|
||||
- teamId: First available team ID (optional)
|
||||
5. Send POST /api/websites with Authorization Bearer token
|
||||
6. Return website ID on success
|
||||
```
|

### Enhanced Error Logging
|
||||
All error messages now include detailed response bodies from Umami API for easier debugging:
|
||||
- Authentication failures show full error response
|
||||
- Website creation errors display Umami's error message
|
||||
- Team fetch failures log warnings but don't block website creation
|
||||
|
||||
### Testing the Fix
|
||||
To verify the fix works:
|
||||
|
||||
1. **Check backend logs** during website creation - you should see:
|
||||
```
|
||||
Creating Umami website: name='...', domain='...'
|
||||
Using team ID: xxx-xxx-xxx (team name: ...)
|
||||
Sending website creation request to Umami API: https://umami.tdvorak.dev/api/websites
|
||||
Successfully created Umami website: ... (ID: xxx, Domain: ...)
|
||||
```
|
||||
|
||||
2. **If teams aren't available**, you'll see:
|
||||
```
|
||||
Failed to fetch user teams (continuing without team): ...
|
||||
Successfully created Umami website: ... (ID: xxx, Domain: ...)
|
||||
```
|
||||
|
||||
3. **Monitor for creation errors** - detailed error messages will help diagnose issues
|
||||
|
||||
This update ensures compatibility with both Umami v1 (no teams) and Umami v2 (with teams).
