Code Block Error

[Drew Olson]

The following code works fine:

counter = 0;
semi_common_tbls.keys.each do |set|
semi_common_tbls[set].each do |table|
outfile << ["CommonTables"+counter.to_s,table]
end
end

However, when I change it like so:

counter = 0;
semi_common_tbls.keys.each do |set|
counter++
semi_common_tbls[set].each do |table|
outfile << ["CommonTables"+counter.to_s,table]
end
end

I get the following error:
tablebuildv2.rb:46: undefined method `+@' for ["table1", "table5"]:Array
(NoMethodError)
from tablebuildv2.rb:42:in `each'
from tablebuildv2.rb:42

What gives?

Thanks,
Drew

Well, it seems you can't use ++ as in Java, changed to +=1.

However, when I change it like so:

counter = 0;
semi_common_tbls.keys.each do |set|
counter++

Ruby doesn't have a ++ operator. Try:

counter += 1

semi_common_tbls[set].each do |table|
outfile << ["CommonTables"+counter.to_s,table]
end
end

I get the following error:
tablebuildv2.rb:46: undefined method `+@' for ["table1",
"table5"]:Array
(NoMethodError)
from tablebuildv2.rb:42:in `each'
from tablebuildv2.rb:42

semi_common_tbls.keys.each do |set|
counter++

'++' is not a Ruby operator, it doesn't have any of the
unary increment/decrement operators.

Closest is
counter += 1
