如何在rails(V4.2.3)中创建批量记录

Question

我尝试一次创建多个记录，但出现错误。

示例：

  Job.find(5601).job_permissions.insert_all(recruiter_id: recruiter.id, job_access_action_id: job_access_action_id.id)

  Job.find(5601).job_permissions.bulk_insert(recruiter_id: recruiter.id, 
  job_access_action_id: job_access_action_id.id)

错误： NoMethodError：JobPermission Load (0.3ms) SELECT job_permissions.* FROM job_permissions WHERE job_permissions.job_id = 5601 #JobPermission::ActiveRecord_Associations_CollectionProxy:0x0055c4da1ceea0

的未定义方法“insert_all”

Answer 1

您需要在 ActiveRecord class 上调用 insert_all，而不是像现在这样 association_proxy，因此：

Job.insert_all([{recruiter_id: ..., {recruiter_id: ...}])

Answer 2

create方法也接受一个数组作为参数。

JobPermission.create(
  [
    { job_id: job.id, recruiter_id: recruiter.id, job_access_action_id: job_access_action_id.id },
    ...
  ]
)
