How can I print each element of an array on its own line in the Rails console?
rails-console, ruby, ruby-on-rails
Solution
Try:
Post.all.each {|e| puts e.inspect }
Thing to notice here is that `puts` function automatically adds a newline character after the statement, and if you instead use `print` it will function in a similar manner as `puts` without the newline character at the end.
If you are using awesome_print, try:
ap Post.all.to_a
Further, when you issue the first command, the output will be repeated at the end (as per your comment) to show the output of the current expression. You can suppress it by appending a ; (semi-colon) at the end of the command, like this:
Post.all.each { |e| puts e.inspect };
Problem
When I run the Rails console, how can I display each item on its own line? Instead of ``` > Post.all => #<ActiveRecord::Relation [#<Post id: 1, title: "Post #0", comment: nil, link: "http://yahoo.com", user_id: 1, created_at: "2013-09-30 02:29:28", updated_at: "2013-09-30 02:29:28">, #<Post id: 2, title: "Post #1", comment: nil,... ``` it would display as ``` > Post.all => #<ActiveRecord::Relation [ #<Post id: 1, title: "Post #0", comment: nil, link: "http://yahoo.com", user_id: 1, created_at: "2013-09-30 02:29:28", updated_at: "2013-09-30 02:29:28">, #<Post id: 2, title: "Post #1", comment: nil,... ``` Similar to `x` in Perl debugger. I tried Post.all.each{|e| e.inspect + "\n"} But that only made it worse, and wasn't very convenient. I saw Ruby on Rails: pretty print for variable.hash_set.inspect ... is there a way to pretty print .inpsect in the console? and https://github.com/michaeldv/awesome_print but that doesn't seem to work ``` irb(main):005:0> require "awesome_print" => false irb(main):006:0> ap Post.all #<ActiveRecord::Relation [#<Post id: 1, title: "Post #0", ```
