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.
