我有Liquor的收藏品(https://github.com/evilmartians/liquor)。我这样用它:

{% for dot in: models.dots do: %}
{% end for%}

我在集合pos_down中有属性dots。我怎么订购这个系列? 这样的事情{% for dot in: models.dots.sort_by('pos_down') do: %}

如果您使用AcctiveRecord,请使用{ "_id" : "kSqH7QydFnPFHQmQH", "timestamp" : ISODate("2015-10-11T11:49:50.241Z"), "dealId" : "X5zTJ2y675PjmaLMx", "deal" : "Games", "price" : [{ "type" : "worth", "value" : "Bat" }, { "type" : "Persons", "value" : 4 }, { "type" : "Cost", "value" : 5 }], "company" : "Company1" } http://guides.rubyonrails.org/active_record_querying.html#ordering
