So I just started with rails a few days ago and I am wondering why this  
does not work. I get an ArgumentError in User#create

Extracted source (around line #2):

1:  
2: \<% form.for :user, @user, :url =\> {:action =\> “create”}, :html =\>  
{:class =\> “create\_form”} do |f| %\>  
3:  
4:

5: \<%= f.label :username %\>

I believe this is what is relevant to what is causing the error

views/user/create.html.erb

\<% form.for :user, @user, :url =\> {:action =\> “create”}, :html =\>  
{:class =\> “create\_form”} do |f| %\>

\<%= f.label :username %\>  
 \<%= f.text\_field :username %\>

\<%= f.label :password %\>  
 \<%= f.text\_field :password %\>

\<%= f.label :first %\>  
 \<%= f.text\_field :first %\>

\<%= f.label :last %\>  
 \<%= f.text\_field :last %\>

\<%= f.label :email %\>  
 \<%= f.text\_field :email %\>

\<%= f.submit\_tag 'Sign Up' %\>

\<% end %\>

controllers/user\_controller.rb

class UserController \< ActionController::Base  
def index  
@users = User.all  
end  
def create  
p params  
@user = User.new  
#@user.first = params[:user][:first]  
#@user.last = params[:user][:last]  
#@user.username = params[:user][:username]  
#@user.password = params[:user][:password]  
end  
end

Yes? And what’s the rest of the error message?

That looks like a typo - it’s form\_for, not form.for

Try to understand the standard 7 object method called restfull API and  
it will make your life easier in rails. Application. Try checking  
[http://railscas.com](http://railscas.com) for a start.

I’m not sure if this is the reason or not, but “form.for” should be  
“form\_for” in views/user/create.html.erb.

Hope this helps.
