form_tag - howto call with self.send?
I have the following code in a form helper Module:
def form_tag_helper(options = {})
url = url_for(:action => "#{@controller.action_name}")
"#{self.send(:form_tag, url, options)}"
end
which I call from several views e.g.
<%= form_tag_helper %>
<table>
<%#= form_input :text_field, "login", :size => 30
%><br/>
<%#= form_input :password_field, "password", :size => 30
%><br/>
</table>
<div class="button-bar">
<%#= button_helper ''login'' %>
<%#= link_helper ''login_signup'', :action =>
''signup'' %>
<%#= link_helper ''login_forgot_password'', :action
=>
''forgot_password'' %>
</div>
The code -- which I have modified from the SaltedHashLoginGenerator
(replace deprecated start_form_tag with form_tag) -- seems to generate
an html form correctly. I am however conscious that form_tag (when
used in the manner above) should have a do...end block surrounding the
form elements and the above code does not respect this.
I would appreciate any views on this and suggestions on how I might
add a do...end block.
Thanks!

In Ruby, you can pass a block (a chunk of code) to a method call, and then run that code by calling yield in the method. This might be what you need... A caveat: I''m pretty much a noob, so anything I say might be wrong :) This page looks like it might be helpful: http://tutorial.jcwcn.com/Web-Design/Ruby-on-Rails/Helpers/2007-08-25/3066.html Good luck!
