| 12 | +# Week 2 |
| 13 | + |
| 14 | +_(June 10, 2025 - June 16, 2025)_ |
| 15 | + |
| 16 | +## Meeting 1 |
| 17 | + |
| 18 | +Meeting for this week didn't happen because I was busy with my end semester examinations |
| 19 | + |
| 20 | +## Progress |
| 21 | + |
| 22 | +Didn't make much progress this week because of my end semester examinations, but still got some work done this week. |
| 23 | + |
| 24 | +- Created a new page under Admin --> Text Management to allow the user to perform CRUD operations for the custom text phrases he want to add. |
| 25 | +- For this, I created a new table called custom_phrase table and made the creation of this table with the existing build process of FOSSology. |
| 26 | +- Tested everything with both docker build process and bare metal installation setup of FOSSology. |
| 27 | + |
| 28 | +### Implementation of the new page |
| 29 | + |
| 30 | +I divided the implementation of the new page into 4 steps. |
| 31 | + |
| 32 | +- Database Foundation |
| 33 | +- Backend Logic |
| 34 | +- User Interface |
| 35 | +- Comprehensive Test Coverage |
| 36 | + |
| 37 | +## Feature Architecture |
| 38 | + |
| 39 | +The implementation follows FOSSology's plugin architecture and MVC pattern: |
| 40 | + |
| 41 | +``` |
| 42 | +├── Database Layer (PostgreSQL) |
| 43 | +│ ├── custom_phrase table |
| 44 | +│ └── Migration scripts |
| 45 | +├── Backend Layer (PHP) |
| 46 | +│ ├── AdminCustomTextManagement controller |
| 47 | +│ └── Database operations |
| 48 | +├── Frontend Layer (Twig Templates + JavaScript) |
| 49 | +│ ├── Management interface |
| 50 | +│ ├── Edit/Add forms |
| 51 | +│ └── Ajax interactions |

| 96 | +## Technical Implementation Details |
| 97 | + |
| 98 | +### Database Schema |
| 99 | + |
| 100 | +The `custom_phrase` table was designed with the following structure: |
| 101 | + |
| 102 | +```sql |
| 103 | +CREATE TABLE custom_phrase ( |
| 104 | + cp_pk SERIAL PRIMARY KEY, -- Auto-incrementing primary key |
| 105 | + rf_fk INTEGER REFERENCES license_ref(rf_pk), -- Foreign key to license |
| 106 | + user_fk INTEGER, -- User who created the entry |
| 107 | + group_fk INTEGER, -- Group association |
| 108 | + text TEXT NOT NULL, -- Main custom text content |
| 109 | + acknowledgement TEXT, -- Acknowledgement text |
| 110 | + comments TEXT, -- Additional comments |
| 111 | + created_date TIMESTAMP DEFAULT CURRENT_TIMESTAMP, -- Creation timestamp |
| 112 | + is_active BOOLEAN DEFAULT TRUE -- Active/inactive status |
| 113 | +); |
| 114 | +``` |
| 115 | + |
| 116 | +**Key Design Features:** |
| 117 | + |
| 118 | +- Foreign key relationship to `license_ref` for data integrity |
| 119 | +- Audit trail with user tracking and timestamps |
| 120 | +- Soft delete mechanism using `is_active` flag |
| 121 | +- Performance indexes on commonly queried fields |
| 122 | + |
| 123 | +### Backend Controller Features |
| 124 | + |
| 125 | +The `AdminCustomTextManagement` controller implements: |
| 126 | + |
| 127 | +**Core Functionality:** |
| 128 | + |
| 129 | +- Full CRUD operations with proper validation |
| 130 | +- Admin-only access with authentication checks |
| 131 | +- Ajax endpoints for real-time operations |
| 132 | +- POST-redirect-GET pattern to prevent duplicate submissions |
| 133 | + |

| 139 | +- CSRF protection and admin access control |
| 140 | + |
| 141 | +**Ajax Endpoints:** |
| 142 | + |
| 143 | +```php |
| 144 | +GET ?action=get_phrases // Data retrieval for DataTables |
| 145 | +POST ?action=delete // Phrase deletion |
| 146 | +POST ?action=toggle // Status toggle |
| 147 | +``` |
| 148 | + |
| 149 | +### Frontend User Interface |
| 150 | + |
| 151 | +**Management Interface Features:** |
| 152 | + |
| 153 | +- Professional DataTables-based listing with sorting and pagination |

| 156 | +- Responsive design for different screen sizes |
| 157 | + |
| 158 | +**Form Interface Features:** |
| 159 | + |
| 160 | +- User-friendly add/edit forms with proper validation |

| 174 | +function createBrowseTable() { |
| 175 | + tableColumns = [ |
| 176 | + { sTitle: "Edit", sClass: "center", bSearchable: false }, |
| 177 | + { sTitle: "Text", sClass: "left", bSearchable: true }, |
| 178 | + // ... more columns |
| 179 | + ]; |
| 180 | +} |
| 181 | + |
| 182 | +function deletePhrase(phraseId) { |
| 183 | + /* Ajax deletion with confirmation */ |
| 184 | +} |
| 185 | +function togglePhraseStatus(phraseId, currentStatus) { |
| 186 | + /* Status toggle via Ajax */ |
