Rails - Oct 2005 - Actionless self-referential views , logic in my views, yes, but less LOC. One draw back, it dont work.

<%= render (:partial => "collapsed_blog" , :locals => {:be
=> be ,
:hide => "yes"}) %>

This above code is in a .rhtml page.

Here is the partial it renders:

<p class=<%="blog_content" + be.id.to_s%>>

<% if hide == "yes" %>
<%= be.blogshorttext %>
	<%= link_to_remote (''  [See Full Text ('' + be.wordcount +
'')]'',
	:update=> ("blog_content" + be.id.to_s),
	:url=> {:partial => ''collapsed_blog'' ,:id =>be.id},
	:locals =>{:hide => "no"})%>
	
<% else %>
<%= be.blog_text %>
	<%= link_to_remote (''  [Collapse]'',
	:update=> ("blog_content" + be.id.to_s),
	:url=> {:partial => ''collapsed_blog'' , :id =>be.id},
	:locals =>{:hide => "yes"})%>
	
<%end%>
</p>

You should notice that both link_to_remotes are attempting
self-reference. Which is not working. When the link is clicked it
should toggle the condition hide, I dont know if it is the framework
forbidding this or if my link_to_remote is malformed or another form
should be used.

I refactored to this code because I didnt like having two actions for
hide and show, I felt I didnt need that. Instead I thought once the
partial is rendered it can submit to itself (see above
link_to_remote). I tried having the locals params inside the :url =>
and also as above outside. Truth is my understanding of the parameters
to link_to_remote is iffy, because I cant find one that excepts locals
even though I am sure they must exist.

 The intial call from the parent correctly renders the partial but if
I click the link [See full text] nothing changes , I am assuming that
the local param is not being passed or set correctly. I want to know
what are your thoughts , should I be using an action here even though
it requires more code, or is there a solution to fix my above
implementation without changing back to action based rendering for
this particular functionality?

You can''t reference partials like that, it only works on render. View
source on the page and see what come up, I bet it won''t be what
you''re
expecting.

I''d use a route to interpret an addition argument for hide to pass to
the action like:
map.connect.blog = ''/blog_controller/collapse_blog/:id/:hide''

Look at the routing wiki for more on defaulting the :hide parameter and
limiting it to a yes or no
