PG :: UndefinedTable - 错误：关系＆＃34; active_storage_attachments＆＃34;不存在

时间：2018-06-11 19:51:27

标签： ruby-on-rails ruby devise rails-admin

我刚为产品和购物车创建了一个简单的应用程序，其中包含名称，价格和附件。它没有任何问题，工作正常。我决定分别使用rails-admin gem和devise创建管理和身份验证。

我按照here所述的说明进行操作。这一切都很好，直到我到达rails_admin部分。除了使用github页面上描述的rails_admin 1.3版本之外，我完成了所描述的所有操作。我也在链接上尝试了旧版本，但每次都遇到此错误

PG::UndefinedTable - ERROR:  relation "active_storage_attachments" does    not exist
 LINE 8:                WHERE a.attrelid = '"active_storage_attachmen...

我没有名称＆＃39; active_storage_attachments＆＃39;的任何表格。我在配置文件中找到了active_storage，所以我猜这可能是由R​​ails配置引起的。任何帮助将不胜感激。如果需要从我的应用中显示一些代码，我会这样做，虽然它已经是一个非常庞大的代码。

提前致谢。

您是否按this page所述运行webpack: Failed to compile. Microsoft.AspNetCore.SpaServices:Error: ERROR in ./node_modules/bootstrap/dist/css/bootstrap.min.css Module build failed: BrowserslistError: Unknown browser major at error

了？我相信这个错误可能是由于您的产品附件和您提到的配置造成的。
