In Ruby, why is it not enough to alias `method_missing` to catch call to undefined methods?


In Ruby, why is it not enough to alias `method_missing` to catch call to undefined methods?



That seems all the more unexpected when defining a dummy method passing all arguments do the job. That is the following works:


def method_missing(ago, *lokatoj, &bloko)
mistrafe(ago, *lokatoj, &bloko)
end

def mistrafe(ago, *lokatoj, &bloko)
# faru ion
end



While the following doen't


alias mistrafe method_missing



Why is that so?

alias mistrafe method_missing does not work because the syntax of alias is:


alias mistrafe method_missing


alias


alias OLD_NAME NEW_NAME



That said, the following will work:


alias method_missing mistrafe

Export result set on Dbeaver to CSV

Export result set on Dbeaver to CSV Normally I use Dbeaver for windows and always export my result set like this: run my query --> select the result --> export the result set --> select export to clipboard --> done This step by step puts my result set in my clipboard and I can paste it wherever I want to work with it. The problem is that now I am using dbeaver for mac and this guide is not working. I can go on until the moment that I select my result set like in the image below: exporting data set But once I go further in the process, in the last step I get: no query Note that in "source" it was suppose to show the query that originated the result set, but instead it says just "select.
