Hi there,

I’m creating a simple login form, and I want the password to be  
validated only on creation (when a user edits, they will edit their  
profile on a separate screen). Therefore, my model looks like this:

validates\_presence\_of :password, :password\_confirmation, :on =\> :create

When I break the form on purpose (don’t fill in a password on creation),  
I get this:

Missing template users/create.html.erb in view path  
cookingfriend/app/views

Why would it be doing that? I can only think it might have something to  
do with my routes? Here’s what I have:

map.resources :users

What could it be?

Thanks!

Show your controller code.

Here’s how it should be:

def new  
@user = User.new  
end

def create  
@user = User.new(params[:user])  
if request.post?  
if @user.save  
session[:user] = User.authenticate(@user.email, @user.password)  
flash[:message] = “You are now a member of Cooking Friend!”  
redirect\_to :action =\> “show”, :id =\> @user.id  
else  
flash[:warning] = “Uh oh. You aren’t signed up.”  
render :action =\> “new” #this is the missing line  
end  
end  
end
