instance method
rewhere
Ruby on Rails edge
Since v4.1.16Signature
rewhere(conditions)Allows you to change a previously set where condition for a given attribute, instead of appending to that condition.
Post.where(trashed: true).where(trashed: false)
# WHERE `trashed` = true AND `trashed` = false
Post.where(trashed: true).rewhere(trashed: false)
# WHERE `trashed` = false
Post.where(active: true).where(trashed: true).rewhere(trashed: false)
# WHERE `active` = true AND `trashed` = false
This is short-hand for unscope(where: conditions.keys).where(conditions). Note that unlike reorder, we’re only unscoping the named conditions – not the entire where statement.
