Question

我已经在Heroku上部署了我的Rails应用程序。但是，我无法通过Heroku控制台保存数据库编辑。

如果我想通过控制台更新模型，请执行以下步骤 -

rails console
@doc = Document.find_by_title('Test’)
@doc.status = 1
@doc.save*

然而，在Heroku模型中，保存不起作用

heroku run rails c
@doc = Document.find_by_title('Test’)
@doc.status = 1
@doc.save

控制台输出如下

   (1.9ms)  BEGIN
   (1.9ms)  BEGIN
  Commontator::Thread Load (1.7ms)  SELECT  "commontator_threads".* FROM "commontator_threads" WHERE "commontator_threads"."commontable_id" = $1 AND "commontator_threads"."commontable_type" = $2 LIMIT 1  [["commontable_id", 40], ["commontable_type", "Document"]]
  Commontator::Thread Load (1.7ms)  SELECT  "commontator_threads".* FROM "commontator_threads" WHERE "commontator_threads"."commontable_id" = $1 AND "commontator_threads"."commontable_type" = $2 LIMIT 1  [["commontable_id", 40], ["commontable_type", "Document"]]
  Approval Load (1.8ms)  SELECT "approvals".* FROM "approvals" WHERE "approvals"."document_id" = $1  [["document_id", 40]]
  Approval Load (1.8ms)  SELECT "approvals".* FROM "approvals" WHERE "approvals"."document_id" = $1  [["document_id", 40]]
  Review Load (1.8ms)  SELECT "reviews".* FROM "reviews" WHERE "reviews"."document_id" = $1  [["document_id", 40]]
  Review Load (1.8ms)  SELECT "reviews".* FROM "reviews" WHERE "reviews"."document_id" = $1  [["document_id", 40]]
   (2.1ms)  ROLLBACK
   (2.1ms)  ROLLBACK

对于我尝试更新的任何属性，这都是相同的。

有什么想法吗？

Answer 1

我想我明白了。它受到验证的影响，如果你想保存并跳过验证，那么

@document.update_columns(status: 1)

或

@document.attribute['status'] = 1
@document.save

两者都会跳过验证。

Answer 2

您也可以试试这个。

heroku run rails c
doc = Document.find_by_title("Test")
doc.status = 1
doc.save(validate: false)

Heroku上的Rails - 通过控制台编辑数据库而不保存
