From 3b49d792231f8051a82cee37c46ac5b23de844db Mon Sep 17 00:00:00 2001 From: Rob Biedenharn Date: Thu, 11 Feb 2016 14:22:09 -0500 Subject: fix to_param to maximize content The documentation states that parameter values longer than 20 characters will be truncated by words, but the example shows that a parameter based on "David Heinemeier Hansson" (with id: 125) becomes "125-david" when "David Heinemeier".length == 16 so why so short? The answer lies in the use of the #truncate option omission: nil which seems to have been intended to mean "nothing", but which actually causes the default string "..." to be used. This causes #truncate to cleave words until the "..." can be added and still remain within the requested size of 20 characters. The better option is omission: '' (which is probably what was originally intended). Furthermore, since the use of #parameterize will remove non-alphanumeric characters, we can maximize the useful content of the output by calling parameterize first and then giving truncate a separator: /-/ rather than a space. --- activerecord/lib/active_record/integration.rb | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'activerecord/lib/active_record') diff --git a/activerecord/lib/active_record/integration.rb b/activerecord/lib/active_record/integration.rb index 466c8509a4..d729deb07b 100644 --- a/activerecord/lib/active_record/integration.rb +++ b/activerecord/lib/active_record/integration.rb @@ -86,7 +86,7 @@ module ActiveRecord # # user = User.find_by(name: 'David Heinemeier Hansson') # user.id # => 125 - # user_path(user) # => "/users/125-david" + # user_path(user) # => "/users/125-david-heinemeier" # # Because the generated param begins with the record's +id+, it is # suitable for passing to +find+.
