Because you aren't doing anything in the create action to adjust the
result if there is a failure. You want something more like this:
def create
@contact = Contact.new(params[:contact])
unless @contact.save
render :action => 'new'
return
end
end
Or this which is pretty close to the default generated by Rails
scaffolding.
def create
@contact = Contact.new(params[:contact])
if @contact.save
flash[:notice] = 'Contact was successfully created.'
redirect_to(contact_path(@contact))
else
render :action => "new"
end
end
