I have the following code:
@@available_columns = [
QueryColumn.new(:tracker, :sortable =>
"#{Tracker.table_name}.position"),
QueryColumn.new(:root_cause, :sortable =>
"#{RootCause.table_name}.position"),
QueryColumn.new(:project, :sortable =>
"#{Project.table_name}.name"),
.....
]
After array initalization I want to revise several elements and delete
them from the array. How can I delete?
