Rails - Jun 2006 - Specifying a Form name using start_/form_tag

Hey all.

I''m trying use the form tag(s) to create a named / id''d form. 
I.e.,
I need to use JS to access the form via the DOM and submit it -  
support for a reusable navigation component which will persist app  
state on each jump.

However, from reading the form_tag APIs and searching google, I don''t  
see where either :name or :id is an option which can be passed into  
the form* tags.  And having tried a number of permutations for  
specifying the additional parameter based on the conventions for  
other tags all result in error.

Any thoughts?

Thanks much,
mx.

I struggled with this same problem for a while. The issue, as you say, 
is how to specify the DOM id of a form when using the form_tag method. 
This is helpful when using things like ''observe_form'', which
requires
the form''s ID.

Try this:

  <%= form_tag( {:action=>''xyz''},
{:id=>''my_form_id''} ) %>

*** The key is to surround your arguments with parenthesis. ***

I could swear that passing multiple hashes without surrounding parens 
works in many other methods, so I''m not sure why it''s a
problem here.

I hope this helps anyone who''s struggled with this.

Ruby doesn''t know if it''s a hash or a block - that''s
why you need
parentheses.  ie:

foo.bar { .... }

the intent of the braces is ambiguous (and is most likely a block),
but

foo.bar( { .... } )

clearly is taking a hash as an argument.
