[Task] Solve the issue with user changing functionality
I went through this defect myself and have solved the issue. We should have a live working session so I can show you how I went through the pain to identify the issue and fix the bug. This can help you build up understanding the complicated connections among various parts of the codes.
-
First, the error message points directly to the
on_clicked
function in./processing/mantid/master_table/import_from_database/oncat_authentication_handler.py
. -
Put in some print-out message and compare the behavior when trying to get access to the login window from different approaches - right click and change user. It seems that both of them are pointing to the same location. So definitely it is not the issue of the hinted location - need to date back to execution history of each approach.
-
For right click approach, search for
Replace ...
and finally we get to the function_import_table_from_database
inprocessing/mantid/master_table/table_tree_handler.py
. -
Look for where
launch_import_from_database_handler
is defined. Needs to know a bit aboutself
and object oriented programming.self
->H3TableHandler
->./processing/mantid/event_handler.py
->h3_table_right_click
->main.py
->self
->launch_import_from_database_handler
->processing/mantid/event_handler.py
->ImportFromDatabaseHandler
->./processing/mantid/master_table/import_from_database/import_from_database_handler.py
-
Compare different between the calling of
OncatAuthenticationHandler
from two different approaches -> copy the properly working one to another.
