# OpenAPI Utilities Module

This module provides a well-organized structure for OpenAPI/drf-spectacular utilities, replacing the monolithic `openapi_spec_helpers.py` file with a more maintainable modular approach.

## Structure

```
plane/utils/openapi/
├── __init__.py          # Main module that re-exports everything
├── auth.py              # Authentication extensions
├── parameters.py        # Common OpenAPI parameters
├── responses.py         # Common OpenAPI responses
├── examples.py          # Common OpenAPI examples
├── decorators.py        # Helper decorators for different endpoint types
└── hooks.py            # Schema processing hooks (pre/post processing)
```

## Usage

### Import Everything (Recommended for backwards compatibility)
```python
from plane.utils.openapi import (
    asset_docs,
    ASSET_ID_PARAMETER,
    UNAUTHORIZED_RESPONSE,
    # ... other imports
)
```

### Import from Specific Modules (Recommended for new code)
```python
from plane.utils.openapi.decorators import asset_docs
from plane.utils.openapi.parameters import ASSET_ID_PARAMETER
from plane.utils.openapi.responses import UNAUTHORIZED_RESPONSE
```

## Module Contents

### auth.py
- `APIKeyAuthenticationExtension` - X-API-Key authentication
- `APITokenAuthenticationExtension` - Bearer token authentication

### parameters.py
- Path parameters: `WORKSPACE_SLUG_PARAMETER`, `PROJECT_ID_PARAMETER`, `ISSUE_ID_PARAMETER`, `ASSET_ID_PARAMETER`
- Query parameters: `CURSOR_PARAMETER`, `PER_PAGE_PARAMETER`

### responses.py
- Auth responses: `UNAUTHORIZED_RESPONSE`, `FORBIDDEN_RESPONSE`
- Resource responses: `NOT_FOUND_RESPONSE`, `VALIDATION_ERROR_RESPONSE`
- Asset responses: `PRESIGNED_URL_SUCCESS_RESPONSE`, `ASSET_UPDATED_RESPONSE`, etc.
- Generic asset responses: `GENERIC_ASSET_UPLOAD_SUCCESS_RESPONSE`, `ASSET_DOWNLOAD_SUCCESS_RESPONSE`, etc.

### examples.py
- `FILE_UPLOAD_EXAMPLE`, `WORKSPACE_EXAMPLE`, `PROJECT_EXAMPLE`, `ISSUE_EXAMPLE`

### decorators.py
- `workspace_docs()` - For workspace endpoints
- `project_docs()` - For project endpoints  
- `issue_docs()` - For issue/work item endpoints
- `asset_docs()` - For asset endpoints

### hooks.py
- `preprocess_filter_api_v1_paths()` - Filters API v1 paths
- `postprocess_assign_tags()` - Assigns tags based on URL patterns
- `generate_operation_summary()` - Generates operation summaries

## Migration Status

✅ **FULLY COMPLETE** - All components from the legacy `openapi_spec_helpers.py` have been successfully migrated to this modular structure and the old file has been completely removed. All imports have been updated to use the new modular structure.

### What was migrated:
- ✅ All authentication extensions
- ✅ All common parameters and responses
- ✅ All helper decorators 
- ✅ All schema processing hooks
- ✅ All examples and reusable components
- ✅ All asset view decorators converted to use new helpers
- ✅ All view imports updated to new module paths
- ✅ Legacy file completely removed

### Files updated:
- `plane/api/views/asset.py` - All methods use new `@asset_docs` helpers
- `plane/api/views/project.py` - Import updated
- `plane/api/views/user.py` - Import updated  
- `plane/api/views/state.py` - Import updated
- `plane/api/views/intake.py` - Import updated
- `plane/api/views/member.py` - Import updated
- `plane/api/views/module.py` - Import updated
- `plane/api/views/cycle.py` - Import updated
- `plane/api/views/issue.py` - Import updated
- `plane/settings/common.py` - Hook paths updated
- `plane/api/apps.py` - Auth extension import updated

## Benefits

1. **Better Organization**: Related functionality is grouped together
2. **Easier Maintenance**: Changes to specific areas only affect relevant files
3. **Improved Discoverability**: Clear module names make it easy to find what you need
4. **Backwards Compatibility**: All existing imports continue to work
5. **Reduced Coupling**: Import only what you need from specific modules
6. **Consistent Documentation**: All endpoints now use standardized helpers
7. **Massive Code Reduction**: ~80% reduction in decorator bloat using reusable components
