Rails - Nov 2005 - Problem with helper form_tag syntax

Hi,

the Rails book says i can use something like this in my view

   <%= form_tag :action => :new, {:class => ''more''} 
%>

This gives an syntax error, whereas only this (ugly looking) works:

   <%= form_tag( {:action => :new} , {:class =>
''more''} ) %>

some ruby syntax stuff i get wrong here?

AFAIK, Ruby collects any hash parameters at the *end* of the argument  
list into a hash. So,

<%= form_tag {:action => :new}, :class => ''more''
%>

may work. On the other hand, IIRC, it is considered deprecated to  
omit the parentheses on functions in views now. You would probably  
get a warning on the above. So the ''minimalist'' correct ERb
code
would probably look like this:

<%= form_tag( {action => :new}, :class => ''more'' )
%>

Hey Brad,

thanks for clarifying this.
