Rails formatting date

Question

I am posting a date to an API and the required format is as follows:

2014-12-01T01:29:18

I can get the date from the model like so:

Answer 1

Create an initializer for it:

# config/initializers/time_formats.rb

Add something like this to it:

Time::DATE_FORMATS[:custom_datetime] = "%d.%m.%Y"

And then use it the following way:

post.updated_at.to_s(:custom_datetime)

⚠️ Your have to restart rails server for this to work.

Check the documentation for more information: http://api.rubyonrails.org/v5.1/classes/DateTime.html#method-i-to_formatted_s
