Creating array, decimal

Rails
1

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

override Hour’s to_s method to return my_hour

Here is the problem:
myhour << h.my_hours

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

[20.0, 0.0, 0.0, 10.0]

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

end
myhour.join(“,”)

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

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

After chaning the datatype to integer…
yes…works

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

Thanks so far

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