Ever wanted to try out any of Rails’ view helper methods in the console? Just include ActionView::Helpers after starting the Rails console: include ActionView::Helpers # => Object text_field(:post, :title) # => "<input id=\"post_title\" name=\"post[title]\" size=\"30\" type=\"text\" />"
Using “try” with a hash to check existence of a key The try method is awesome. Check the documentation. It is usually used to call a method on an object if it exists, or return nil if it doesn’t. But sometimes, it is not used with hashes, but this also works perfectly: params[:search] ? params[:search][:name] : nil # Can also be written as... params[:search].try(:[],:name)
