Usage

<count:comments/> -> <span class="count">1 Comment</span>

<count:viewings/> -> <span class="count">3 Viewings</span>

The label can be customised using the label attribute, e.g.

<count:comments label="blog post comment"/> -> <span class="count">12 blog post comments</span>

Additional Notes

Use the prefix attribute to insert words before the count. If the prefix is “are” or “is” then it will be pluralised if needed:

  There <count:comments prefix="are"/> -> There <span class="count">is 1 Comment</span>
  There <count:viewings prefix="are"/> -> There <span class="count">are 3 Viewings</span>

Use the lowercase attribute to force the generated label to be lowercase:

  <count:comments lowercase/> -> <span class="count">1 comment</span>

Use the if-any attribute to output nothing if the count is zero. This can be followed by an <else> tag to handle the empty case:
```
  <count:comments if-any/><else>There are no comments</else>
```

<def attrs='label, prefix, if-any, lowercase' tag='count'><span class='count'><%=
  raise Exception.new("asked for count of a string") if this.is_a?(String)
   
  c = this.try.to_int || this.try.total_entries || (this.try.loaded? && this.try.length) || this.try.count || this.try.length

  label ||= if this.is_a?(Class)
              this.view_hints.model_name
            elsif (attr = this.try.origin_attribute)
              this.member_class.view_hints.field_name(attr).singularize
            else
              this.member_class.view_hints.model_name
            end.titleize

  label = label.downcase if lowercase
   
  Hobo::Dryml.last_if = c > 0 if if_any
  if if_any && c == 0
    ""
  else
    main = label.blank? ? c : pluralize(c, label)
   
    if prefix.in? %w(are is)
      prefix = c == 1 ? "is" : "are"
    end

    (prefix ? "#{prefix} #{main}" : main.to_s)

  end
