Hi Team,
I am having a similar problem, also following along from railscast 32.
Any suggestions welcome. Is it an erb thing or something wrong with my
model code? Also :formdate is a date field not a datetime field.
==========
View throws this ERROR PAGE:
ArgumentError in Contracts#new
Showing app/views/contracts/new.html.erb where line #84 raised:

def formdate_string
formdate.to_s(:db)

end

<div class="onecol"><%= f.label :formdate, "Date" %><br />
<%= f.text_field :formdate_string %></

Thank you.
