难道 find 有缓存
def find_one(id)
id = id.id if ActiveRecord::Base === id
if IdentityMap.enabled? && where_values.blank? &&
limit_value.blank? && order_values.blank? &&
includes_values.blank? && preload_values.blank? &&
readonly_value.nil? && joins_values.blank? &&
!@klass.locking_enabled? &&
record = IdentityMap.get(@klass, id)
return record
end
column = columns_hash[primary_key]
substitute = connection.substitute_at(column, @bind_values.length)
relation = where(table[primary_key].eq(substitute))
relation.bind_values = [[column, id]]
record = relation.first
unless record
conditions = arel.where_sql
conditions = " [#{conditions}]" if conditions
raise RecordNotFound, "Couldn't find #{@klass.name} with #{primary_key}=#{id}#{conditions}"
end
record
end
如果 IdentityMap 没开应该没缓存啊。
装了什么插件吗?
#3 楼 @Rei https://github.com/lshgo/mongo_organizational 可能是转换模型 database 的问题吧!但是 where 怎么会没有查到呢!
