Best_in_place display_with not finding helper

Question

There's not a lot of documentation as to how to use the display_with option in Best In place, but I'm trying to get Best_in_Place to display dates in condensed form, (mm/dd/yyyy). My db (sqlserver) has the dates stored in datetime format, and I use this command to display the field:

<%= best_in_place(@production, :budget_approval_internal,  type: :date, :nil => "[Not    set]")  %>

When clicked the gem works as expected, putting up a calendar control to select the date, and then displaying it in short form. But when I press refresh I get a date that looks like:

 2013-12-04 00:00:00 UTC    

So I thought I could use the :display_with option to have use a helper that looks like this:

def format_date(my_date)
   my_date.strftime('%m/%d/%Y')
end

I put this in the application_helper.rb module and then tried this:

 <%= best_in_place(@production, :budget_approval_internal,  type: :date, :display_with => :format_date, :nil => "[Not    set]")  %>

but I get an error in saying:

"can't find helper format_date. Any ideas?

Answer 1

Either you should include ApplicationHelper in your controller or add the method to the appropriate helper file.
Edit : You need to open the ActionView::Base class and add your method

module ActionView  
    class Base  
        def format_date(rec)  
            rec.strftime('%m/%d/%Y')  
        end  
    end  
end
