erb tempate issue

[Juan Sierra Pons]

Hi

I am creating a module to populate a file. The result should be like this:

uri ldap://10.10.10.1 ldap://10.10.10.2 ldap://10.10.10.3

To achieve this I am using an array with the IPs declared on the
ldap_servers array and the following erb template:

uri <% if !@ldap_servers.empty? -%>
ldap://<%= @ldap_servers %>
<% end -%>

The ouput I get is like this:

uri ldap://10.10.10.1ldap://10.10.10.2lado://10.10.10.3

Without the space between the ips.

I have also tried this (with no success):

uri <% if !@ldap_servers.empty? -%>
ldap://<%= @ldap_servers %> <%= %>
<% end -%>

I think this is an easy one but after several tries I have decided to ask here.

Thank you for your time

Best regards

Just add a space in front of ldap://<%= ….

Hi

uri ldap://http://10.10.10.1http://10.10.10.2http://10.10.10.2

Thank you for your time

Remove the space after uri and add the space in front of ldap://…

Hi

Finally I have changed to another kind on loop that works for my case

uri<% @ldap_servers.each do |server| -%>
ldap://<%= server -%>
<% end %>

Thank you for your time

Best regards

As you've found, an explicit loop, er, iterable is better than trying to use implicit conversion of an array to a string.

An alternative is to use the 'join' method; that will put the separator only between the elements, rather than having to have it before or after each. This would be clearly better with a comma or other non-whitespace separator.
