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?

What do you get in the text_area if you do that? -Dave -- Dave Aronson: Available Cleared Ruby on Rails Freelancer (NoVa/DC/Remote) -- see www.DaveAronson.com, and blogs at www.Codosaur.us, www.Dare2XL.com, www.RecruitingRants.com -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

What do you get in the text_area if you do that?---- .join("\r\n") did the trick. Needed to use double quotes and not single quotes (don''t understand why). Thanks... actually just stumbled onto this and was going back to my e-mail program to give it the old Roseanne Rosannadanna and saw your suggestion and the answer is yes (above) Thanks Craig -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

For the simple reason that single quotes in Ruby do not allow for string interpolation (such as \r and \n), while double quotes do.

sure but that was in the model and by the time the ''string'' reached the view, the \r and \n were ''bare'' (no quotes) so in my mind, they should not have been a factor at all.
