I am new to rails and found areally nice looking plugin for date selection here:
I have installed it according to the instructions, but when I try to
change one of the date selections to use the plugin, I get something
undefined method `calendar_date_select_tag' for #<ActionView::Base:0x176aa4c>
Extracted source (around line #45):
44: <%= f.date_select :date_of_birth %>
45: <!-- <%= calendar_date_select_tag "e_date" %> -->
How do I do this?
