Feature #13706: Allow CSV#delete to delete multiple columns or add #delete_columns method
https://bugs.ruby-lang.org/issues/13706
* Author: wowinter13 (Vladislav Dyachenko)
* Status: Open
* Priority: Normal
* Assignee:
* Target version:
----------------------------------------
I duplicated the main report message from this PR: https://github.com/ruby/csv/pull/4
The basic idea is that now we can delete only one column using #delete
`csv_table.delete("PassengerId")
csv_table.delete("Survived")
csv_table.delete("Name")
csv_table.to_csv`
The best working way for me to do it with multiple columns:
`
to_del = ["Name", "Ticket"]
csv_table = datus.by_col!.delete_if { |name, values| !to_del.include? name}`
But maybe it should work like this?
`
to_del = ["Name", "Ticket"]
data.delete(to_del)`
