Thanks for your prompt reply. It wasn't the new line, but that
difference was well spotted.
I found it... makes sense now... ArgumentError... it wasn't getting
passed an argument for a new form. The form worked for the edit action
when the field was populated.
I needed to initialize the formdate field with a value. So I added
this to the "new" action of the controller.
eg.
def new
@contract = Contract.new
@contract.formdate = Time.now.localtime.strftime("%Y-%m-%d")
end
Would you say this is good practice? or could I do it better elswhere
or with different code?
Cheers.
