Ruby on Rails中的内联数据格式

Question

Within a rails app I have a .jst.eco template which includes the line...

<span> <%= @event.get 'create_at' %> </span> 

...which renders the date like so 2015-01-17 11:04:03.

However I only want to display 2015-01-17. Is there a neat formatting trick I can use within the <%= ... %>?

Answer 1

You can write as:

span> <%= @event.get('create_at').to_s(:db) %> </span>
# or
span> <%= @event.get('create_at').to_formatted_s(:db) %> </span>

:db means '%Y-%m-%d . Check out DATE_FORMATS .

Answer 2

It depends on the object you have. If it is a time object, you can do:

@event.get('create_at').strftime('%F')

if it is just a string, then first you should parse it:

Time.parse(@event.get('create_at')).strftime('%F')

According to .strftime docs %F is The ISO 8601 date format (%Y-%m-%d)
