# Business Logic Specification
|
|
|
|
## Overview
|
|
AI StyleGallery is a web application that enables users to transform their uploaded images using various AI-generated artistic styles through integration with external AI services.
|
|
|
|
## Core Business Requirements
|
|
|
|
### Primary User Journey
|
|
1. **Image Upload**: Users can upload personal images to their gallery
|
|
2. **Style Selection**: Users can browse and select from available AI artistic styles
|
|
3. **AI Processing**: Selected images are sent to external AI services for style transformation
|
|
4. **Result Management**: Users can view styled results and choose to keep (make permanent) or discard them
|
|
5. **Gallery Management**: Users can view their collection of original and styled images
|
|
|
|
### Key Business Rules
|
|
- **Image Privacy**: Images are private by default, users control visibility
|
|
- **Temporary Processing**: AI-styled images are initially temporary until user confirms
|
|
- **Style Availability**: Only enabled styles from active AI models are available to users
|
|
- **Provider Flexibility**: Support multiple AI service providers (ComfyUI, RunwareAI, etc.)
|
|
- **Real-time Progress**: Users receive real-time updates during AI processing
|
|
|
|
## Core Business Workflows
|
|
|
|
### 1. Image Style Transformation Workflow
|
|
|
|
#### Process Flow
|
|
```
|
|
User selects image → Opens context menu → Chooses "Change Style" →
|
|
Browses style selector → Selects style → Initiates AI processing →
|
|
Receives real-time progress updates → Views styled result →
|
|
Chooses to keep or discard the styled image
|
|
```
|
|
|
|
#### Technical Implementation
|
|
- Frontend captures user selection via Vue.js components
|
|
- Backend validates request and loads appropriate AI plugin
|
|
- Plugin handles communication with external AI service
|
|
- Real-time progress tracked via WebSocket (ComfyUI) or polling (other providers)
|
|
- Styled image saved to storage and database record created
|
|
- User notified of completion and can manage result
|
|
|
|
#### Success Criteria
|
|
- Processing completes within reasonable time (typically 30-180 seconds)
|
|
- User receives clear progress feedback during processing
|
|
- Styled image maintains acceptable quality and resolution
|
|
- User can easily keep or discard results
|
|
|
|
### 2. Gallery Management Workflow
|
|
|
|
#### Image Synchronization
|
|
- Automatic sync between filesystem and database
|
|
- Missing files removed from database
|
|
- New files added to database with metadata
|
|
- Maintains data consistency across application restarts
|
|
|
|
#### Visibility Rules
|
|
- **Public Images**: Visible to all users
|
|
- **Private Images**: Only visible to image owner
|
|
- **Temporary Images**: Visible to owner during processing/review period
|
|
- **Authenticated Users**: See all their own images
|
|
- **Unauthenticated Users**: See only public images and their temporary results
|
|
|
|
### 3. Admin Management Workflow
|
|
|
|
#### Content Management
|
|
- **Styles**: Create, edit, enable/disable artistic styles
|
|
- **AI Models**: Configure available AI models and their parameters
|
|
- **API Providers**: Set up connections to external AI services
|
|
- **Users**: Manage user accounts and assign roles
|
|
- **Settings**: Configure application-wide settings
|
|
|
|
#### Quality Assurance
|
|
- Preview images for styles before publishing
|
|
- Test connections to AI services
|
|
- Monitor processing success rates
|
|
- Manage storage and cleanup old temporary files
|
|
|
|
## Business Entities & Relationships
|
|
|
|
### Primary Entities
|
|
- **Users**: Account holders with roles and preferences
|
|
- **Images**: Uploaded files with metadata and processing status
|
|
- **Styles**: AI artistic styles with prompts and parameters
|
|
- **AI Models**: Specific AI models (e.g., Stable Diffusion variants)
|
|
- **API Providers**: External AI services (ComfyUI, RunwareAI, etc.)
|
|
|
|
### Key Relationships
|
|
- **User → Images**: One-to-many (users own multiple images)
|
|
- **Image → Style**: Many-to-one (multiple images can use same style)
|
|
- **Style → AI Model**: Many-to-one (multiple styles can use same model)
|
|
- **AI Model → API Provider**: Many-to-one (multiple models can use same provider)
|
|

|
|
|
|
## Business Constraints & Validation Rules
|
|
|
|
### Data Validation
|
|
- **Image Files**: Must be valid image formats (JPEG, PNG, WebP), max 10MB

|
|
- **API URLs**: Must be valid, accessible endpoints
|
|
- **User Email**: Must be unique and valid format
|
