Question

我需要实现以下目标：

queryable.any_of(
      between(:average_nightly_min_price,  [10,100]),
      between(:average_nightly_max_price,  [110,1100])
  )

是否可以使用any_of和between的组合。还是其他任何替代方案？

Answer 1

queryable.any_of(
  queryable.between(:average_nightly_min_price,  [10,100]).selector,
  queryable.between(:average_nightly_max_price,  [110,1100]).selector
)

如果嵌入了iqueryable，它就不起作用。

对于2.0之前的ruby版本：

queryable.any_of(
      queryable.between(average_nightly_min_price => [10,100]).selector,
      queryable.between(average_nightly_max_price => [110,1100]).selector
    )

Answer 2

我还有ArgumentError（如@christofferjoergensen），但mongoid 3.1.5

使用hashrocket语法而不是传递两个参数解决了它：

queryable.any_of(
  queryable.between(:average_nightly_min_price => [10,100]).selector,
  queryable.between(:average_nightly_max_price => [110,1100]).selector
)

any_of和之间的mongoid组合
