Introduction to Expertiza
Background
Expertiza is an open source project based on Ruby on Rails framework. Expertiza allows the instructor to create new assignments and customize new or existing assignments. It also allows the instructor to create a list of topics the students can sign up for. Students can form teams in Expertiza to work on various projects and assignments. Students can also peer review other students' submissions. Expertiza supports submission across various document types, including the URLs and wiki pages.
Problem Statement
The following were the tasks identified to accomplish through this project. These tasks are part of the review_response_map.rb, assignment.rb and metareview_response_maps.
- P1: Code Climate shows import method is complex, because of lots of checks. This method can be fixed by adding private methods for raising import error. However, you need to check if this functionality is called anywhere.
- P2: Get_assessments_round_for method can be renamed to get_responses_for_team_round. Team_id private variable is not needed.
- P3: metareview_response_maps rename, refactoring can be done. No need to do second iteration.
- P4: Assignment Branch Condition size for final_versions_from_reviewer is too high.
- P5: Assignment Branch Condition size for get_assessments_round_for is too high, try to get rid of the nested if.
- P6: Use find_by instead of where.first, e.g. line 60, 65, etc.
- P7: Wrap the over-long lines: 58, 62 and 181.
- P8: Write missing unit tests for existing methods.
Reason for Refractor
The purpose of this work is to rewrite the code of seven file for several reason listed below.
Files Modified in this Project
- review_response_map.rb
- assignment.rb
- metareview_response_maps
Solutions implemented and Delivered
P1: Code Climate shows import method is complex, because of lots of checks. This method can be fixed by adding private methods for raising import error. However, you need to check if this functionality is called anywhere.
We could find a call to the import method from 4 relevant places in the importFile method in the ImportFileController. Of them 2 are for different models and the other 2 are having different number of parameters. Therefore we concluded that the import method in the review_response_map.rb is not called from anywhere and so we dropped the method.
