My question is similar to this SO problem, but it does not answer my question:

Rails 3 default datetime format without UTC

I understand that I can add

Time::DATE_FORMATS[:default] = "%Y/%m/%d"

to my environment.rb and it will change my default time format accordingly.

So when I do Time.now.to_s I get the correct format.

However, my question is, how come this does not work with a form_builder. For example:

<%= f.text_field :date %>

will return a full UTC timestamp: 2013-01-25 07:45:21

I am aware that I can do this

<%= f.text_field :date, :value => @post.date.to_s %>

And it will give me the correct format.

But this solution seems hacky to me. Is this really the only way to do it?

    How would you like your input to look like? The Rails [date_select](http://api.rubyonrails.org/classes/ActionView/Helpers/DateHelper.html#method-i-date_select) helper is really flexible to customize and might fit your needs better than a text-field. – Thomas Klemm Jan 25 '13 at 07:57

I am not 100% sure. But the answer is most likely no. The rails formhelper just gives you whatever value that is in your database.

Here is where the value is retrieved for your reference:

http://api.rubyonrails.org/classes/ActionView/Helpers/InstanceTag.html#method-i-to_input_field_tag

There is no special processing of it, such as localize or to_s, which is where formatting is applied.

If the date looks like a timestamp (2013-01-25 07:45:21 UTC),

You could do something like the following to views you localize timestamps with:

<%= localize(@post.date, :format => :long) %>

According to your problem, you could try using date_select rather than text_field.

<%= f.date_select :date, :order => [:day, :month, :year] %>

  • I am not sure this is the answer he is looking for. He is specifically asking how to get the correct format using the form builder. – vinhboy Jan 25 '13 at 16:54
