On Ruby on Rails, how do we print debug info inside of a controller?
In the controller you can:
render :text => @some_object.inspectBut your view won't be rendered.
You could also:
Rails.logger.debug("My object: #{@some_object.inspect}")and run tail on log/development.log to see the output.
In the view the recommeneded way is:
<%= debug(@some_object) %>
Don't know about print, but puts never failed me. Your hello world will be in console and logs and normal flow will continue.
Did I understand you correctly?
You can debug in the view: <%= debug @post %>. More info: http://guides.rubyonrails.org/debugging_rails_applications.html
