How to remove last comma when iterating through hash in erb template
...ine in a config file in the format x = "ip1,ip2,ip3"
I am using the method below to sort the hash before iterating over it.
However, as you can see there will always be a final comma which breaks the
app that uses this config file. Does anyone know how I could remove the
final comma?
ipv4_bind_addresses = "<% routes.sort_by {|key, v| key}.each do |key, v|
-%><%= net %>.<%= v[''pubnet''] %>.1,<% end -%>"
