How to change created_at format

Question

This should be a simple thing. Well, Im sure it should be simple, this is rails.

The problem is: in the model all data has a field created_at. to retrieve this info in the view I use a block, where is a line t.created_at.

It shows me a result like 2015-04-12 11:04:44 UTC

Which method should I use to show this date as 2015-04-12? As I suppose it should be something like that: t.created_at.date_only

Could you help me?

You can read more about strftime here

t.created_at.strftime("%Y-%m-%d")

And it can be done even easier way:

t.created_at.to_date

Or with locales:

// view:
<% @articles.each do |c| %>
    <%= l c.created_at.to_date, format: :short %>
<% end %>

Answer 4

Sometimes we resort to the following technique, but I don't recommend it

class ApplicationRecord < ActiveRecord::Base
  self.abstract_class = true

  def created_at
    attributes['created_at'].strftime("%Y-%m-%d %H:%M")
  end
end
