Creating array, decimal

[Werner]

Hi
I have an attribute decimal => hour

If I do

hours.each do |h|
      h.my_hour
end
I get => 20.0 0.0 0.0 10.0

And this..
myhour = []
hours.each do |h|
myhour << hour
end
myhour.join(",")

I get =>
<Hour:0x007f81feec3330>,#<Hour:0x007f81feaa0c30>,

How do I get something like this ?
20.0, 0.0, 0.0, 10.0

Thanks for support

Here is the problem:

  myhour << h.my_hours 

end
myhour.join(",")

Well my be I am a litte stubborn today..
What I need is an array

After chaning the datatype to integer..
yes..works

 but as decimal (6,2)
stays : <Hour:0x007f81feec3330>,#<Hour:0x007f81feaa0c30>,

Thanks so far

That should be
myhour << h.myhour
though myhour is a very poor name for an array. It should be plural.

That it because you are adding Hour objects into the array, not decimal objects.

Carlos did point out the problem earlier. It is worth reading the answers
carefully when you ask a question.
