Help for hash, thanks

Ruby
1

hello, I am newcomer in Ruby. These days I develop with ruby-sdk on
aws, when I put items into dynamoDB. First I use Array putItems:

ngrid=100
putItems = Array.new(ngrid)

every element in putItems is a hash instance

putItems[i]={:latitude => str[j], :longitude => str[j+1], :u

=>str[j+2]}

I use API to put items into DynamoDB as following:

batch.put('grb2datatest2', [putItems[1],putItems[2]])

this is ok, Now, I want put all elements in array putItems into table,
but I don’t know how to write this setence, the following is obviously
wrong,

batch.put('grb2datatest2',[putItems.join(",")])

for putItems.join return a string, while the params for batch.put is:

batch.put('tablename', [hash1, hash2, hash3, ...]
batch.process!

what I need is a hash with a ‘,’ list in [], who know how program the
code?
thanks!

putItems by himself is what you want, is an #Array of hashes.
Inspect objects with “puts(putItems.inspect)”, to see how they looks
like.
