How to output a different date format. Rails

Question

I am using Ruby On Rails 4 and twitter-bootstrap-rails, to the client wants to dislay dates in this format:

14 September 2013 Well pretty cool, there we go:

    var start = $("#project_start_date").datepicker({
        format: 'dd MM yyyy',
        autoclose: true
    })

However when the date is saved to the database it is saved as "2013-09-14". Well cool, however when I want to edit the page I see the following:

2013-09-14 as the output of the field :( Not good hey.

So how would you output the date in a given format (I probably need @start_date.stftime("%d %B %Y").

Just wanted to say, that:

getter methods didn't do the job: def start_date() @start_date.stftime("%d %B %Y") end
before_validation also didn't do:

 
before_validation :date_validation

  def date_validation
    @start_date = self.start_date.strftime("%D %m %Y")
    @end_date =   self.end_date.strftime("%d %m %Y")
  end

PS I am using Postgres.

Are you saving the date as as a string or date in the database? — Zero Fiber

When you say 'didn't do the job', you mean it didn't work as expected or was there an error? If so, what was the error? — Rajesh Kolappakam

In any case, instead of adding the date formatting code in your model, you should consider using draper or any other presentation layer concept. railscasts.com/episodes/286-draper — Rajesh Kolappakam

Check whether the date is being stored as a string in the database as thats what it seems.

Try generating a migration and making sure you have a date column, something like this

def change    
   change_column :table_name, :start_date, :datetime
   change_column :table_name, :end_date, :datetime
end

That way, you can then use strftime to format it as you mentioned above.

To change the format in which the date is saved in the database, add this piece of code to the environment.rb file.

# environment.rb :

ActiveSupport::CoreExtensions::Date::Conversions::DATE_FORMATS.merge!(
     :default => "%d %B %Y"
)

I decided to make this old Q complete by answering it.

Aside from using draper that was mentioned in a comment, the easiest way is to override AR getter, not in a validation, i.e.

# in your model
def start_date
  self[:start_date].strftime("%D %m %Y")
end
