Using Rails 3.1.1 and trying to switch over to Ruby 1.9.3-p125 (I've got 1.9.3-p125 running via NGINx and 1.8.7 running via webrick so I can side by side).
I've got the following in my 'host' model (activeldap but I don't that matters) def hostipnumbers_columnized if self.ipHostNumber == nil then results = else results = self.ipHostNumber.to_a.sort {|a,b| a <=> b }.collect { |ipnumber| ipnumber + "\n" } end return results end
# Note: had to add '.to_a' to the method because sort is no longer a string option and in 1.8.7 when only 1 ipHostNumber is returned, it's just a simple string but ruby 1.8.7 never complained but ruby 1.9.3 comes to a screeching halt
Anyway, in my view, I've got...
<%= text_area 'host', 'hostipnumbers_columnized', :cols => '30', :rows => '8' %>
which when running on 1.8.7 was never an issue. Each ip address was put onto a new line because of the '\n' like this: 10.200.0.100 208.100.300.100
but when running on 1.9.3-p125 the text_area shows the array with all of it's raw markup like this: ["10.200.0.100\n", "208.100.300.100\n"]
I've done various things such as flattening, joining, etc. the hostipnumbers_columnized but it appears impossible to get them to display on individual lines in ruby-1.9.3 - without even considering code that will work equally as well with 1.8.7
Any suggestions?
