|
## Primary Reference: Documentation
|
|
|
|
**ALWAYS consult these files BEFORE implementing:**
|
|
|
|
```bash
|
|
# Main reference - read this FIRST
|
|
cat custom/docs/ESPOCRM_BEST_PRACTICES.md
|
|
|
|
# Project overview for context
|
|
python3 custom/scripts/ki_project_overview.py
|
|
|
|
# Specific topics
|
|
cat custom/docs/TESTERGEBNISSE_JUNCTION_TABLE.md # Junction Tables
|
|
cat custom/CUSTOM_DIRECTORY.md # File structure
|
|
cat custom/README.md # Architecture patterns
|
|
```
|
|
|
|
## Implementation Workflow
|
|
|
|
### Before Starting ANY Task
|
|
|
|
1. **Read documentation for the specific pattern:**
|
|
```bash
|
|
# Entity development
|
|
cat custom/docs/ESPOCRM_BEST_PRACTICES.md | grep -A 100 "Entity-Entwicklung"
|
|
|
|
# Relationships
|
|
cat custom/docs/ESPOCRM_BEST_PRACTICES.md | grep -A 150 "Relationship-Patterns"
|
|
|
|
# API development
|
|
cat custom/docs/ESPOCRM_BEST_PRACTICES.md | grep -A 150 "API-Entwicklung"
|
|
```
|
|
|
|
2. **Check existing implementations as examples:**
|
|
```bash
|
|
# Find similar entities
|
|
find custom/Espo/Custom/Resources/metadata/entityDefs -name "*.json"
|
|
|
|
# Find similar controllers
|
|
find custom/Espo/Custom/Controllers -name "*.php"
|
|
```
|
|
|
|
3. **Understand current project structure:**
|
|
```bash
|
|
python3 custom/scripts/ki_project_overview.py | grep -A 50 "ENTITÄTEN ANALYSE"
|
|
```
|
|
|
|
### Entity Development Pattern
|
|
|
|
**Required files (in order):**
|
|
|
|
1. **Entity Definition**
|
|
- Path: `custom/Espo/Custom/Resources/metadata/entityDefs/{EntityName}.json`
|
|
- Template from: ESPOCRM_BEST_PRACTICES.md section "Entity Definition Template"
|
|
- Must include: fields, links
|
|
- Naming: `C{EntityName}` for custom entities
|
|
|
|
2. **Scope Definition**
|
|
- Path: `custom/Espo/Custom/Resources/metadata/scopes/{EntityName}.json`
|
|
- Template from: ESPOCRM_BEST_PRACTICES.md section "Scope Definition"
|
|
- Configure: tab, acl, stream, calendar
|
|
|
|
3. **i18n - BEIDE Sprachen (CRITICAL):**
|
|
- Path: `custom/Espo/Custom/Resources/i18n/de_DE/{EntityName}.json`
|
|
- Path: `custom/Espo/Custom/Resources/i18n/en_US/{EntityName}.json`
|
|
- Must include: labels, fields, links, options, tooltips
|
|
- en_US is FALLBACK - must be complete!
|
|
|
|
4. **Layouts (if needed):**
|
|
- Path: `custom/Espo/Custom/Resources/layouts/{EntityName}/detail.json`
|
|
- Path: `custom/Espo/Custom/Resources/layouts/{EntityName}/list.json`
|
|
- **CRITICAL**: Use `{}` not `false` as placeholder (EspoCRM 7.x+)
|
|
|
|
5. **Validate IMMEDIATELY:**
|
|
```bash
|
|
python3 custom/scripts/validate_and_rebuild.py
|
|
```
|
|
|
|
### Relationship Implementation Pattern
|
|
|
|
**CRITICAL: Relationships must be BIDIRECTIONAL**
|
|
|
|
**One-to-Many Example:**
|
|
```json
|
|
// Parent Entity (CMietobjekt)
|
|
{
|
|
"links": {
|
|
"mietverhltnisse": {
|
|
"type": "hasMany",
|
|
"entity": "CVmhMietverhltnis",
|
|
"foreign": "mietobjekt" // ← Must point to link name in child
|
|
}
|
|
}
|
|
}
|
|
|
|
// Child Entity (CVmhMietverhltnis)
|
|
{
|
|
"fields": {
|
|
"mietobjektId": {"type": "varchar", "len": 17},
|
|
"mietobjektName": {"type": "varchar"}
|
|
},
|
|
"links": {
|
|
"mietobjekt": {
|
|
"type": "belongsTo",
|
|
"entity": "CMietobjekt",
|
|
"foreign": "mietverhltnisse" // ← Must point to link name in parent
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
**Many-to-Many with Junction Table:**
|
|
```json
|
|
// Both entities need identical relationName
|
|
// Entity 1
|
|
{
|
|
"links": {
|
|
"relatedEntities": {
|
|
"type": "hasMany",
|
|
"entity": "EntityB",
|
|
"foreign": "relatedFromA",
|
|
"relationName": "EntityAEntityB" // ← MUST MATCH
|
|
}
|
|
}
|
|
}
|
|
|
|
// Entity 2
|
|
{
|
|
"links": {
|
|
"relatedFromA": {
|
|
"type": "hasMany",
|
|
"entity": "EntityA",
|
|
"foreign": "relatedEntities",
|
|
"relationName": "EntityAEntityB" // ← MUST MATCH
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
**Junction Table with additionalColumns:**
|
|
- Follow: `custom/docs/TESTERGEBNISSE_JUNCTION_TABLE.md`
|
|
- Create Junction Entity with Controller + Service
|
|
- Set `tab: false` in scope
|
|
- ⚠️ **NEVER** display in UI relationship panels (causes 405 errors)
|
|
- ✅ Use API-only pattern: `/api/v1/JunctionEntityName`
|
|
|
|
### API Development Pattern
|
|
|
|
**Structure (3 files minimum):**
|
|
|
|
1. **Controller:**
|
|
```php
|
|
<?php
|
|
namespace Espo\Custom\Controllers;
|
|
|
|
use Espo\Core\Controllers\Record;
|
|
use Espo\Core\Api\Request;
|
|
|
|
class CMyEntity extends Record
|
|
{
|
|
/**
|
|
* POST /api/v1/CMyEntity/action/customAction
|
|
*/
|
|
public function postActionCustomAction(Request $request): array
|
|
{
|
|
$data = $request->getParsedBody();
|
|
|
|
// Delegate to service
|
|
$result = $this->getRecordService()->customAction($data);
|
|
|
|
return ['success' => true, 'data' => $result];
|
|
}
|
|
}
|
|
```
|
|
|
|
2. **Service:**
|
|
```php
|
|
<?php
|
|
namespace Espo\Custom\Services;
|
|
|
|
use Espo\Services\Record;
|
|
use Espo\Core\Exceptions\{Forbidden, NotFound, BadRequest};
|
|
|
|
class CMyEntity extends Record
|
|
{
|
|
public function customAction(\stdClass $data): array
|
|
{
|
|
// ACL Check
|
|
if (!$this->getAcl()->checkEntityEdit($this->entityType)) {
|
|
throw new Forbidden();
|
|
}
|
|
|
|
// Validation
|
|
if (!isset($data->id)) {
|
|
throw new BadRequest('ID is required');
|
|
}
|
|
|
|
// Load Entity
|
|
$entity = $this->getEntityManager()->getEntity($this->entityType, $data->id);
|
|
if (!$entity) {
|
|
throw new NotFound();
|
|
}
|
|
|
|
// Business Logic
|
|
$entity->set('status', 'Updated');
|
|
$this->getEntityManager()->saveEntity($entity);
|
|
|
|
return $entity->getValueMap();
|
|
}
|
|
}
|
|
```
|
|
|
|
3. **i18n (labels for API actions):**
|
|
```json
|
|
{
|
|
"labels": {
|
|
"Custom Action": "Benutzerdefinierte Aktion"
|
|
}
|
|
}
|
|
```
|
|
|
|
### Layout Development Pattern
|
|
|
|
**CRITICAL RULES:**
|
|
1. EspoCRM 7.x+ requires `{}` not `false` as placeholder
|
|
2. bottomPanelsDetail.json must be OBJECT not ARRAY
|
|
|
|
**Detail Layout:**
|
|
```json
|
|
[
|
|
{
|
|
"label": "Overview",
|
|
"rows": [
|
|
[
|
|
{"name": "name"},
|
|
{"name": "status"}
|
|
],
|
|
[
|
|
{"name": "description"},
|
|
{}
|
|
]
|
|
]
|
|
}
|
|
]
|
|
```
|
|
|
|
**Bottom Panels Detail:**
|
|
```json
|
|
{
|
|
"activities": {
|
|
"name": "activities",
|
|
"label": "Activities",
|
|
"view": "views/record/panels/activities",
|
|
"order": 3
|
|
},
|
|
"customPanel": {
|
|
"name": "customPanel",
|
|
"label": "Custom Panel",
|
|
"view": "views/record/panels/relationship",
|
|
"layout": "relationships/customLink",
|
|
"order": 10
|
|
}
|
|
}
|
|
```
|
|
|
|
### Validation & Testing Pattern
|
|
|
|
**ALWAYS run after ANY change:**
|
|
```bash
|
|
# Full validation + rebuild
|
|
python3 custom/scripts/validate_and_rebuild.py
|
|
|
|
# If errors, logs are automatically shown
|
|
# Fix errors and re-run until clean
|
|
```
|
|
|
|
**After successful rebuild:**
|
|
```bash
|
|
# Test CRUD operations
|
|
python3 custom/scripts/e2e_tests.py
|
|
|
|
# Manual API test
|
|
curl -X GET "https://crm.example.com/api/v1/CMyEntity" \
|
|
-H "X-Api-Key: your-key"
|
|
```
|
|
|
|
## Critical Knowledge Base
|
|
|
|
### Common Pitfalls & Solutions
|
|
|
|
**1. Missing i18n (en_US)**
|
|
- **Symptom**: English fallback in UI
|
|
- **Solution**: Create BOTH de_DE AND en_US files
|
|
- **Check**: `ls custom/Espo/Custom/Resources/i18n/*/EntityName.json`
|
|
|
|
**2. Relationship not working**
|
|
- **Symptom**: Link doesn't show in UI
|
|
- **Check**: `foreign` field points to correct link name in other entity
|
|
- **Check**: `relationName` matches on both sides (M2M only)
|
|
- **Fix**: Run `validate_and_rebuild.py` - it checks this automatically
|
|
|
|
**3. Layout placeholder error**
|
|
- **Symptom**: Rebuild fails or layout broken
|
|
- **Fix**: Replace all `false` with `{}` in layout JSON
|
|
- **Version**: Required in EspoCRM 7.x+
|
|
|
|
**4. 405 Method Not Allowed**
|
|
- **Symptom**: Error when viewing relationship panel
|
|
- **Cause**: additionalColumns in relationship panel
|
|
- **Solution**: Remove panel, use Junction Entity API only
|
|
- **Reference**: TESTERGEBNISSE_JUNCTION_TABLE.md
|
|
|
|
**5. ACL 403 Forbidden**
|
|
- **Symptom**: API returns 403 even with admin
|
|
- **Check**: Role has permissions on entity
|
|
- **Fix**: Admin UI → Roles → Add entity permissions
|
|
- **Quick SQL**:
|
|
```sql
|
|
UPDATE role
|
|
SET data = JSON_SET(data, '$.table.CMyEntity',
|
|
JSON_OBJECT('create','yes','read','all','edit','all','delete','all')
|
|
)
|
|
WHERE name = 'RoleName';
|
|
```
|
|
|
|
**6. Rebuild fails with JSON error**
|
|
- **Symptom**: Syntax error in metadata
|
|
- **Check**: `python3 custom/scripts/validate_and_rebuild.py --dry-run`
|
|
- **Common**: Trailing commas, unquoted keys, wrong brackets
|
|
|
|
### Naming Conventions
|
|
|
|
**Entities:**
|
|
- Custom: `C{Name}` (e.g., `CMietobjekt`)
|
|
- VMH prefix: `CVmh{Name}` (e.g., `CVmhMietverhltnis`)
|
|
- Junction: `{EntityA}{EntityB}` (e.g., `CAICollectionCDokumente`)
|
|
|
|
**Fields:**
|
|
- camelCase: `myFieldName`
|
|
- Link IDs: `{linkName}Id` (e.g., `mietobjektId`)
|
|
- Link Names: `{linkName}Name` (e.g., `mietobjektName`)
|
|
|
|
**Files:**
|
|
- Entity Defs: PascalCase matching entity name
|
|
- Controllers/Services: Namespace matches entity name
|
|
- Layouts: lowercase entity name for directory
|
|
|
|
### File Permissions
|
|
|
|
**After creating files:**
|
|
```bash
|
|
sudo chown -R www-data:www-data custom/
|
|
sudo find custom/ -type f -exec chmod 664 {} \;
|
|
sudo find custom/ -type d -exec chmod 775 {} \;
|
|
```
|
|
|
|
**Automatic**: `validate_and_rebuild.py` fixes permissions
|
|
|
