value not stored in array ruby on rails

I initialize array 

k = Array.new

then something like 

@m = Modul.where(:rfp_id => @rfp.id)
i = 0
for ii in @m
  k = ii.name.to_s
  i = i + 1
end

and then 

 k.each do |a|
    ...
 end

but value is not stored in "k" how can i do this?

Change this k = ii.name.to_s to k.push(ii.name.to_s). It will work. You did not anywhere add the item ii.name.to_s to your array k. k = ii.name.to_s means in each loop iteration, you are going to reference a new string object to the local variable k. Read Array#push to get introduce yourself to the method.

Don't need to write k = Array.new, ratherk = [] is enough for your purpose.

Try write clean code, for example:

Modul.where(:rfp_id => @rfp.id).pluck(:name).each do |name|
  puts name
end
