Activity 1Experiment with the following expressions:
<%= 1+2 %>
<%= "cow" + "boy" %>
- Time in one hour:
<%= 1.hour.from_now %>
Hint: pay close attention to the time zone as it will be reported in Universal Coordinated Time, some times referred to as GMT.
A call to the following Ruby method returns a list of all the files in the current directory:
@files = Dir.glob('*')
Use it to set an instance variable in a controller action, and then write the corresponding template that displays the filenames in a list on the browser.
Hint: you can iterate over a collection using something like this:
<% for file in @files %>file name is:
<%= file %>
<% end %>
Hint You might want to use a
<ul> for the list.
