Details

Equivalent to <nil-view> if this is nil
Equivalent to <count> if this is an Array
Equivalent to <type-name> if this is a class
If the context has a name_attribute defined, equivalent to <view:abc/> (where abc is the name attribute)
Finally falls back to this.to_s (html escaped), but only if the user has view permission for this

Attributes

if-present: if given, nothing at all will be rendered for nil values (as opposed to rendering <nil-view>)

<def attrs='if-present' tag='name'><%= 
  if this.nil?
    nil_view unless if_present
  else
    if this.is_a?(Array)
      count
    elsif this.is_a?(Class)
      type_name(attributes)
    elsif (name_attr = this.class.try.name_attribute) && can_view?(this, name_attr)
      view(merge_attrs(attributes, {:field => name_attr}))
    elsif can_view?(this)
      h this.to_s
    end
  end
%></def>
