我想保存这样的数据:
User.create(name:"Guy", properties:{url:["url1","url2","url3"], street_address:"asdf"})
我可以在Rails 4中这样做吗？到目前为止,我尝试过迁移:
add_column :users, :properties, :hstore, array: true
但是当我在hstore中保存数组时,它返回错误:
PG::InvalidTextRepresentation: ERROR: array value must start with "{" or dimension information
