How do I set the name of a form in Rails? -

i tried

<%= form_tag ("/ombcauth", name:"ombc_form") %>

but gave me syntax error:

syntax error, unexpected ',', expecting ')' ...append= form_tag ("/ombcauth", name:"ombc_form") @output...

i tried

<%= form_tag ({action:"/ombcauth"}, {name:"ombc_form"}) %>

but gave me syntax error

syntax error, unexpected ',', expecting ')' ...form_tag ({action:"/ombcauth"}, {name:"ombc_form"}) @outp...

i need reference form in link submit.

<%= link_to "ombc auth", "#", {onclick: "document.ombc_form.submit(); return false;"} %>

rails --version
rails 3.2.11

what did correct. problem in white space between form_tag , (:

<%= form_tag("/ombcauth", name:"ombc_form") %>

or without parenthesis:

<%= form_tag "/ombcauth", name:"ombc_form" %>

hope helps!
