Have a look at the following code: from simple_wsgi import route, dbsession from myapp.dbmodel import Job, Result @route("/api/v2/merge_jobs?uuids=") def merge_jobs(uuids): """Merge results from multiple jobs with the""" jobs_to_delete = [] job_query = dbsession.query( raw("SELECT id, uuid FROM job WHERE uuid IN %s ORDER BY id;" % str(tuple(uuids))) ) primary = job_query.next() for job in job_query: result_query = dbsession.query( raw("SELECT id, job_id FROM result WHERE job_id = '%s';" % job.id) ) for result in results_query: result.job_id = primary.id dbsession.add(result) jobs_to_delete.append(job) dbsession.commit() for job in jobs_to_delete: dbsession.delete(job) dbsession.commit() This is a part of a RESTful API for an application implemented in simple WSGI framework and database engine. The application stores test Results for the test Jobs. Each job can have multiple results, and sometimes the Results from multiple Jobs are merged into one Job. The method shown in the code sample takes a list of UUIDs from the URL-encoded data, and moves the Results from all the Jobs to the first one, deleting the 'empty' Jobs. Assume the code executes, but there are some conceptual design flaws. Can you identify them?
