I have a drop down in my forms.

Year Manufactured The value needs to be from 1970 – current year

In the new form i am using the following code

-- Select -- \<%= options\_from\_collection\_for\_select((1970..Time.now.year).collect {|p| [p, p] }, "first", "last") %\>

I want to be able to show the items in reverse order. Where the most  
recent year shows first.

Also in the edit form i want similar code but with the selected item to  
be the one that is present in the database. How can i achieve this?

You could use select\_year

You could start by reading the api docs  
([ActionView::Helpers::DateHelper](http://api.rubyonrails.org/classes/ActionView/Helpers/DateHelper.html#M001677)  
)

Thanks for the help so far, but using this i am running into more issues  
that before, I am not getting the field name as i want it using  
:field\_name to specify the vehicle[year\_made] gives me  
date[vehicle[year\_imported]] and also the prompt does not show.

So guiding me to the API is not helping me solving my problem. Any other  
solutions.

you need to play with the the :prefix option to change date to  
something else.

Thanks for this, now two more questions remain.

I still need to have a custom value like – Select – added in there.

And also for edit time, how do i make it that it shows the value from db  
already selected?
