Arg, I've successully posted tags using gmail before, I don't know why
it failed this time. Trying again.
<!-- Repeats the body of the tag inside a `<ul>` list with one item
for each object in the collection (`this`). If no body is given,
renders a `<card>` inside the `<li>`.
Automatically adds 'even' and 'odd' CSS classes.
`empty-collection-message` is called from this tag. To suppress you
can use the `without-empty-message` pseudo-attribute:
<collection without-empty-message/>
If your collection is an ActiveRecord result set (and in Hobo it most
likely is), the best way to customize the empty message is via
translations. Example: for product models, the key to customize
would be `products.collection.empty_message`.
If your collection is a generic array, empty-collection-message
doesn't work. `<collection>` also sets the last_if flag, so you can
use the `<else>` tag to display a message:
<collection with="&[]"/>
<else>No items.</else>
### Attributes
- list-tag: set to 'ol' if you prefer that over 'ul'.
-->
<def tag="collection" attrs="list-tag">
<% list_tag ||= 'ul' %>
<call-tag tag="&list_tag" class="collection
#{collection_name :dasherize => true}" merge-attrs unless="empty?">
<li param="item" class="#{scope.even_odd} #{model_id_class}"
repeat="&select_viewable">
<do param="default"><card param/></do>
</li>
</call-tag>
<empty-collection-message param="empty-message"/>
<if/><%# set last-if so <else/> works %>
</def>
<!-- Renders a message such as "No products to display". If the
collection (`this`) is empty, `style="display:none"` is added. This
means the message is still present and can be revealed with JavaScript
if all items in the collection are removed via ajax remove buttons.
-->
<def tag="empty-collection-message">
<unless test="&this._?.member_class.nil?">
<div class="empty-collection-message" style="#{'display:none' if !
this.empty?}" param="default">
<ht
key="#{this.member_class.name.underscore}.collection.empty_message">
No <collection-name/> to display
</ht>
</div>
</unless>
</def>
