Syntax with link_to using block, remote, parameters and class/id
Rails 3rc, Ruby 1.9.2
Newish to rails; very new to rails3
I''m trying to create a link using a block so I can wrap the name
contents in a span, for an ajax request using multiple parameters and finally,
also specifying the class and id of the generated link element. Here''s
what I''ve got so far:
<%= link_to(
:url=>{
:controller => ''themes'', :action =>
''remove_tag'',
:entity_id => entity_id, :theme_id => theme_id,
:entity => entity, :element_id => element_id,
:parent_id=>parent_id
},
:remote => true,
:id => "theme-tag-#{entity}-#{entity_id}",
:class => "tag") do %>
<span class=''subtract''><%= tag %></span>
<% end %>
This generates the following:
<a
href="/explore/index/theme-tag-user-3?url[controller]=themes&url[action]=remove_tag&url[entity_id]=3&url[theme_id]=16&url[entity]=user&url[element_id]=filter-contributor-3&url[parent_id]=filter-contributors&remote=true&class=tag"><span
class="subtract">Test Descriptor</span></a>
So, the href isn''t correct, no class or id attributes as
they''re being treated like parameters instead, and normally with
:remote=>true, I''d expect to see data-remote=true in the element.
Also, and this is just my desire to learn more about why... but a link_to
without a block would be something like link_to "Link Name",
{url_stuff...}, :remote=>true, :class="my-class",
:id=>"1" and so on, and these all work, but why do I have to
specify the :url=> when using the block, but not otherwise? It just seems
there''s a significant syntactical difference between the two and I
don''t understand why there would be and I''d like to. Thanks.
Bill

yeah, you were passing a hash and not a helper method On Thu, Sep 9, 2010 at 11:39 AM, William K.
