basic question ruby store value from table to array

I read that initialitation of array in ruby is like myarray = [apple.txt, house.txt]

How can I store the value of a table in an array

if !haus.blank?
            #from below, I will get a list of haus.name that I need to store in an array 
            haus.each do |f|
                   hausname = haus.name
          end
end

i need to store each of the haus.name that I get from iterating in haus table to

myarray=[listofhaus.name开发者_Python百科]

How can I do this in ruby?

Thank you for your help

You can get all the array of names using the map

 myarray = haus.map {|f| f.name} or
 myarray = haus.map(&:name)

myarray = haus.collect(&:name)

I take i you're on Rails. Since your each iteration doesn't really make sense, here's a generic example:

Haus.all.map {|h| h.name }

This get's all objects of model Hause and maps the name attribute of each into an array.
