单个哈希插入数组的多个 SQL 语句

Question

I am doing something like this to insert multiple records at the same time in my rails app.

VoteRecord.create(
  [
    { :prospect_id => prospect.id, :state => "OH", :election_type => "GE" },
    { :prospect_id => prospect.id, :state => "OH", :election_type => "PR" }
    ...
   ]  
)

When I check the log i see that the insert query is fired multiple times by sql. Is it possible to do this in a single query?

Answer 1

您可以尝试使用活动记录导入进行批量导入、签出 wiki 和示例页面。

Answer 2

我自己没有使用过它，但你应该查看 activerecord-import 项目（对于 Rails 3） github更多关于这方面的信息可以在这里找到： wiki
