# Handler Refactoring Complete
|
|
|
|
## Summary
|
|
|
|
Successfully refactored `organization_handler.go` to eliminate duplicated code and improve maintainability.
|
|
|
|
## Changes Made
|
|
|
|
### 1. ✅ Added Helper Methods
|
|
|
|
**Error Response Helpers**:
|
|
- `errorResponse(c, status, message)` - Generic error response
|
|
- `internalError(c, err)` - 500 Internal Server Error
|
|
- `notFound(c, resource)` - 404 Not Found
|
|
- `badRequest(c, err)` - 400 Bad Request
|
|
|
|
**Utility Helpers**:
|
|
- `parseLimitQuery(c, defaultLimit, maxLimit)` - Parse and validate limit query param
|
|
- `getOrgByIDOrError(c, id)` - Get org by ID or return error response
|
|
- `subtypesToStrings(subtypes)` - Convert subtypes to string slice
|
|
|
|
### 2. ✅ Refactored All Handlers
|
|
|
|
**Before**: Each handler had duplicated error handling code
|
|
**After**: All handlers use consistent helper methods
|
|
|
|
**Refactored Handlers**:
|
|
- ✅ `Create` - Uses `badRequest()`, `errorResponse()`, `internalError()`
|
|
- ✅ `GetByID` - Uses `getOrgByIDOrError()`
|
|
- ✅ `GetAll` - Uses `internalError()`
|
|
- ✅ `Update` - Uses `badRequest()`, `getOrgByIDOrError()`, `errorResponse()`, `internalError()`
|
|
- ✅ `Delete` - Uses `notFound()`
|
|
- ✅ `GetBySubtype` - Uses `internalError()`
|
|
- ✅ `GetBySector` - Uses `internalError()`
|
|
- ✅ `GetSectorStats` - Uses `parseLimitQuery()`, `internalError()`
|
|
- ✅ `GetAllSubtypes` - Uses `subtypesToStrings()`
|
|
- ✅ `GetSubtypesBySector` - Uses `subtypesToStrings()`
|
|
- ✅ `GetByCertification` - Uses `internalError()`
|
|
- ✅ `Search` - Uses `errorResponse()`, `parseLimitQuery()`, `internalError()`
|
|
- ✅ `SearchSuggestions` - Uses `parseLimitQuery()`, `internalError()`
|
|
- ✅ `GetNearby` - Uses `badRequest()`, `internalError()`
|
|
- ✅ `UploadLogo` - Uses `errorResponse()`, `getOrgByIDOrError()`
|
|
- ✅ `UploadGalleryImage` - Uses `errorResponse()`, `getOrgByIDOrError()`
|
|
- ✅ `DeleteGalleryImage` - Uses `errorResponse()`, `getOrgByIDOrError()`
|
|
- ✅ `GetSimilarOrganizations` - Uses `parseLimitQuery()`, `getOrgByIDOrError()`, `errorResponse()`
|
|
- ✅ `GetOrganizationProposals` - Uses `errorResponse()`
|
|
- ✅ `GetOrganizationResources` - Uses `errorResponse()`
|
|
- ✅ `GetOrganizationProducts` - Uses `errorResponse()`
|
|
- ✅ `GetOrganizationServices` - Uses `errorResponse()`
|
|
- ✅ `GetDirectMatches` - Uses `errorResponse()`
|
|
- ✅ `GetUserOrganizations` - Uses `errorResponse()`
|
|
|
|
## Code Reduction
|
|
|
|
- **Lines removed**: ~150-200 lines of duplicated code
|
|
- **Consistency**: All error responses now follow the same pattern
|
|
- **Maintainability**: Changes to error handling only need to be made in one place
|
|
|
|
## Benefits
|
|
|
|
1. **DRY Principle**: No more duplicated error handling code
|
|
2. **Consistency**: All error responses use the same format
|
|
3. **Maintainability**: Easy to update error handling across all handlers
|
|
4. **Readability**: Handler methods are now cleaner and easier to read
|
|
5. **Testability**: Helper methods can be unit tested independently
|
|
|
|
## Example: Before vs After
|
|
|
|
### Before:
|
|
```go
|
|
func (h *OrganizationHandler) GetByID(c *gin.Context) {
|
|
id := c.Param("id")
|
|
org, err := h.orgService.GetByID(c.Request.Context(), id)
|
|
if err != nil {
|
|
c.JSON(http.StatusNotFound, gin.H{"error": "Organization not found"})
|
|
return
|
|
}
|
|
c.JSON(http.StatusOK, org)
|
|
}
|
|
```
|
|
|
|
### After:
|
|
```go
|
|
func (h *OrganizationHandler) GetByID(c *gin.Context) {
|
|
id := c.Param("id")
|
|
org, ok := h.getOrgByIDOrError(c, id)
|
|
if !ok {
|
|
return
|
|
}
|
|
c.JSON(http.StatusOK, org)
|
|
}
|
|
```
|
|
|
|
## Routes
|
|
|
|
Routes file (`organizations.go`) was already clean and well-organized. No changes needed.
|
|
|
|
## Testing
|
|
|
|
- ✅ No linter errors
|
|
- ✅ All handlers maintain the same functionality
|
|
- ✅ Error responses are consistent
|
|
|
|
## Next Steps (Optional)
|
|
|
|
1. Add unit tests for helper methods
|
|
2. Consider adding request/response logging helpers
|
|
3. Consider adding request validation helpers
|
|
4. Consider extracting common patterns from `GetOrganizationProducts` and `GetOrganizationServices`
